Laravel Resource route NotFoundHttpException - php

I am using the resource route to access several crud functions on my site but I am getting a NotFoundHttpException error when accessing one of several pages. This was working this earlier and I don't think I have changed anything.
Route::resource('/contractors', 'ContractorController');
The specific ContractorController method:
public function skills($id)
{
$contractor = Contractor::find($id);
return View::make('contractors.skills')
->with('contractor', $contractor);
}
I have all of the basic crud methods located in the ContractorController too. I am using the skills method to create a new view that edits tags in a pivot table
my url is public/contractors/1/skills and this blade view:
contractors/skills.blade.php
Do you see anything that I am doing wrong?

There's only a few routes that Resource controllers by default will handle, you can see a full list of them (7 in all) in the documentation entry for Resource Controllers.
The skills URI segment is not one of them. You will need to add a separate route for that:
Route::get('/contractors/{contractorId}/skills', 'ContractorController#skills');
However, this isn't really RESTful design. You may be better off with a separate skills resource.

How to organize views in Laravel breeze?

This may be a dumb question, but I've started exploring Laravel Breeze with vue and I'm not sure how to manage resources and their views. (Using Laravel 9)
For example, if I have a table 'members' and a resource controller 'MemberController', ordinarily in the web.php file I would do something like:
Route::resource('members', MemberController::class)->names('members');
Then I'd create a 'member' folder in my resource/views folder to store the views for that table. I could then call the view from the MemberController something like:
public function index()
{
$members = Member::all();
return view('member.index', compact('members'));
}
I'm trying to do something similar using vue in breeze, so I guess I'd have the vue pages in the 'resources/js/Pages' folder. But this didn't seem to work properly.
I don't know how to transition from the previous approach of handling resources and views to Breeze using vue.
What's the recommended way to handle resources in an SPA with Breeze/vue?
After following Djave's suggestion, I took a look at the sample app from inertia.js and that answered everything.
The problem I had was due to using the dot notation when specifying the path to the vue page. So, in my example above, it should instead be like this:
return view('Member/Index', compact('members'));
The inertia sample app code has a lot of good examples!

Wrong controller is being used for edit route ( using Laravel resource helper )

I'm currently using laravel 5.4 and I have stumbled upon something I can't fix.
I'm currently trying to bind a route to a controller using the Laravel resource helper as such :
Route::resource('campaigns', 'CampaignsController');.
I correctly see my route being there when I do a PHP artisan:route list, I have all my CRUD endpoints tied to the appropriate controller function. Also, note that I'm currently doing that for all my route that need to be tied to a CRUD system ( what I'm working with is mostly form ) without any problem
With this being said, whenever I'm trying to edit a Campaign, I get an error : Class App\Http\Controllers\Ads\Campaigns does not exist
I do not know why it's trying to look for a Campaigns controller while I specify the CampaignsController controller. Everything is behaving correctly in campaigns route, except the edit one. Also, all my other routes have the same logic and never faced this problem.
Any idea why it is looking for the wrong Controller ?
Here's my namespace declaration and folder hierarchy, which is ok ( please note that the adsController has its routes declared the same way and is used the same way too )
here's my edit method
and here's the error
It's quite possible that you try to inject not existing class in your controller.
Take a look at controller constructor or edit route if you don't have something like this:
public function edit(Campaigns $campaigns)
{
}
and make sure you import Campaigns from valid namespace (probably it's not in App\Http\Controllers\Ads namespace.
If it doesn't help try to find in your app directory occurrences of Ads\Campaigns to see where it's used. Sometimes problem can be in completely different part of your application.
EDIT
Also make sure you didn't make any typo. In error you have Campaigns but your model is probably Campaign - is it possible that in one place you have extra s at the end?
Try with Route::resource('campaigns', 'Ads\CampaignsController'); in your web.php file

Dealing with Views in Phalcon Controllers

I am working on a newly created Phalcon project, and I don't really know how to actually use multiples views.
What is the entry point? I don't really know when each method in the controller is called, under which conditions, etc.
Where is the control flow defined? is it based in the name of the view? or is there a place where you can register them?
Phalcon is a bit different than other well-known PHP frameworks, in that not much is pre-configured or pre-built by default. It's quite loosely-coupled. So you have to decide where and how your control flow will work. This means that you will need to dig deeper in the documentation and also that there could be different way to achieve the same thing.
I'm going to walk you through a simple example and provide references, so you can understand it more.
1) You would start by defining a bootstrap file (or files) that will define the routes, or entry points, and will setup and create the application. This bootstrap file could be called by an index.php file that is the default file served by the web server. Here is an example of how such bootstrap file will define the routes or entry points (note: these are just fragments and do not represent all the things that a bootstrap file should do):
use Phalcon\Di\FactoryDefault;
// initializes the dependency injector of Phalcon framework
$injector = new FactoryDefault();
// defines the routes
$injector->setShared('router', function () {
return require_once('some/path/routes.php');
});
Then it the routes.php file:
use Phalcon\Mvc\Router;
use Phalcon\Mvc\Router\Group as RouterGroup;
// instantiates the router
$router = new Router(false);
// defines routes for the 'users' controller
$user_routes = new RouterGroup(['controller' => 'users']);
$user_routes->setPrefix('/users');
$user_routes->addGet('/show/{id:[0-9]{1,9}}', ['action' => 'show']);
$router->mount($user_routes);
return $router;
Im defining routes in an alternate way, by defining routes groups. I find it to be more easy to organize routes by resource or controller.
2) When you enter the url example.com/users/show/123, the routes above will match this to the controller users and action show. This is specified by the chunks of code ['controller' => 'users'], setPrefix('/users') and '/show/{id:[0-9]{1,9}}', ['action' => 'show']
3) So now you create the controller. You create a file in, let's say, controllers/UsersController.php. And then you create its action; note the name that you used in the route (show) and the suffix of Action:
public function showAction(int $id) {
// ... do all you need to do...
// fetch data
$user = UserModel::findFirst(blah blah);
// pass data to view
$this->view->setVar('user', $user);
// Phalcon automatically calls the view; from the manual:
/*
Phalcon automatically passes the execution to the view component as soon as a particular
controller has completed its cycle. The view component will look in the views folder for
a folder named as the same name of the last controller executed and then for a file named
as the last action executed.
*/
// but in case you would need to specify a different one
$this->view->render('users', 'another_view');
}
There is much more stuff related to views; consult the manual.
Note that you will need to register such controller in the bootstrap file like (Im also including examples on how to register other things):
use Phalcon\Loader;
// registers namespaces and other classes
$loader = new Loader();
$loader->registerNamespaces([
'MyNameSpace\Controllers' => 'path/controllers/',
'MyNameSpace\Models' => 'path/models/',
'MyNameSpace\Views' => 'path/views/'
]);
$loader->register();
4) You will also need to register a few things for the views. In the bootstrap file
use Phalcon\Mvc\View;
$injector->setShared('view', function () {
$view = new View();
$view->setViewsDir('path/views/');
return $view;
});
And this, together with other things you will need to do, particularly in the bootstrap process, will get you started in sending requests to the controller and action/view defined in the routes.
Those were basic examples. There is much more that you will need to learn, because I only gave you a few pieces to get you started. So here are some links that can explain more. Remember, there are several different ways to achieve the same thing in Phalcon.
Bootstrapping:
https://docs.phalconphp.com/en/3.2/di
https://docs.phalconphp.com/en/3.2/loader
https://docs.phalconphp.com/en/3.2/dispatcher
Routing: https://docs.phalconphp.com/en/3.2/routing
Controllers: https://docs.phalconphp.com/en/3.2/controllers
More on Views (from registering to passing data to them, to templating and more): https://docs.phalconphp.com/en/3.2/views
And a simple tutorial to teach you some basic things: https://docs.phalconphp.com/en/3.2/tutorial-rest
The application begins with the routing stage. From there you grab the controller and action from the router, and feed it to the dispatcher. You set the view then call the execute the dispatcher so it access your controller's action. From there you create a new response object and set its contents equal to the view requests, and finally send the response to the client's browser -- both the content and the headers. It's a good idea to do this through Phalcon rather than echoing directly or using PHP's header(), so it's only done at the moment you call $response->send(); This is best practice because it allows you to create tests, such as in phpunit, so you can test for the existence of headers, or content, while moving off to the next response and header without actually sending anything so you can test stuff. Same idea with exit; in code, is best to avoid so you can write tests and move on to the next test without your tests aborting on the first test due to the existence of exit.
As far as how the Phalcon application works, and in what steps, it's much easier to follow the flow by looking at manual bootstrapping:
https://docs.phalconphp.com/en/3.2/application#manual-bootstrapping
At the heart of Phalcon is the DI, the Dependency Injection container. This allows you to create services, and store them on the DI so services can access each other. You can create your own services and store them under your own name on the DI, there's nothing special about the names used. However depending on the areas of Phalcon you used, certain services on the DI are assumed like "db" for interacting with your database. Note services can be set as either shared or not shared on the DI. Shared means it implements singleton and keeps the object alive for all calls afterwards. If you use getShared, it does a similar thing even if it wasn't initially a shared service. The getShared method is considered bad practice and the Phalcon team is talking about removing the method in future Phalcon versions. Please rely on setShared instead.
Regarding multiple views, you can start with $this->view->disable(); from within the controller. This allows you to disable a view so you don't get any content generated to begin with from within a controller so you can follow how views work from within controllers.
Phalcon assumes every controller has a matching view under /someController/someView followed by whatever extension you registered on the view, which defaults to .volt but can also be set to use .phtml or .php.
These two correspond to:
Phalcon\Mvc\View\Engine\Php and Phalcon\Mvc\View\Engine\Volt
Note that you DON'T specify the extension when looking for a template to render, Phalcon adds this for you
Phalcon also uses a root view template index.volt, if it exists, for all interactions with the view so you can use things like the same doctype for all responses, making your life easier.
Phalcon also offers you partials, so from within a view you can render a partial like breadcrumbs, or a header or footer which you'd otherwise be copy-pasting into each template. This allows you to manage all pages from the same template so you're not repeating yourself.
As far as which view class you use within Phalcon, there's two main choices:
Phalcon\Mvc\View and Phalcon\Mvc\View\Simple
While similar, Phalcon\Mvc\View gives you a multiple level hierarchy as described before with a main template, and a controller-action based template as well as some other fancy features. As far as Phalcon\Mvc\View\Simple, it's much more lightweight and is a single level.
You should be familiar with hierarchical rendering:
https://docs.phalconphp.com/en/3.2/views#hierarchical-rendering
The idea is with Phalcon\Mvc\View that you have a Main Layout (if this template exists) usually stored in /views/index.volt, which is used on every page so you can toss in your doctypes, the title (which you would set with a variable the view passed in), etc. You'd have a Controller Layout, which would be stored under /views/layouts.myController.volt and used for every action within a controller (if this template exists), finally you'd have the Action Layout which is used for the specific action of the controller in /views/myController/myAction.volt.
There are all types of ways you can break from Phalcon's default behavior. You can do the earlier stated $this->view->disable(); so you can do everything manually yourself so Phalcon doesn't assume anything about the view template. You can also use ->pick to pick which template to use if it's going to be different than the controller and action it's ran in.
You can also return a response object from within a controller and Phalcon will not try to render the templates and use the response object instead.
For example you might want to do:
return $this->response->redirect('index/index');
This would redirect the user's browser to said page. You could also do a forward instead which would be used internally within Phalcon to access a different controller and/or action.
You can config the directory the views are stored with setViewsDir. You can also do this from within the controller itself, or even within the view as late as you want, if you have some exceptions due to a goofy directory structure.
You can do things like use $this->view->setTemplateBefore('common') or $this->view->setTemplateAfter('common'); so you can have intermediate templates.
At the heart of the view hierarchy is <?php echo $this->getContent(); ?> or {{ content() }} if you're using Volt. Even if you're using Volt, it gets parsed by Phalcon and generates the PHP version with $this->getContent(), storing it in your /cache/ directory, before it is executed.
The idea with "template before" is that it's optional if you need another layer of hierarchy between your main template and your controller template. Same idea with "template after" etc. I would advise against using template before and after as they are confusing and partials are better suited for the task.
It all depends on how you want to organize your application structure.
Note you can also swap between your main template to another main template if you need to swap anything major. You could also just toss in an "if" statement into your main template to decide what to do based on some condition, etc.
With all that said, you should be able to read the documentation and make better sense of how to utilize it:
https://docs.phalconphp.com/en/3.2/api/Phalcon_Mvc_View

Laravel resourceful controller - differentiate an API call from a browser

I have a single route defined like this:
Route::resource('problem', 'ProblemController');
The moment I POST to /problem, a ProblemController#store method is fired.
Now what I want is to return a JSON response if it's an API call or a view (or maybe redirect) if I'm on the "web-side" of my application. How can I approach this problem?
Should I create separate controllers? Should I (in every method/controller) detect the type of the request and respond accordingly? Should I use middlewares? Route groups? Separate application?
The main goal is to have multiple application types (API + versioning + web) in one package but share the business logic, models and most of the code (to avoid repeating).
I am using Laravel 5.2.
Thank you!
Request object offers a method wantsJson() that checks Accept header of the request and returns TRUE if JSON was requested.
In your controller you can do the following:
if( request()->wantsJson() )
{
return ['foo' => 'bar'];
}
return view('foo.bar');
You can read more about content negotiation in Laravel here: http://fideloper.com/laravel-content-negotiation
You can create a route group like this:
Route::group(['prefix'=>'api'], function(){
//All routes in this route become domain.com/api/route
});
This makes the most sense to me because a route that returns a view and an API route are two separate things. You should have a controller for the pages and views you want to show in your app, and another one for the api routes that update and change your data, returning JSON.

Laravel :: Routes Vs. Controller

As I am new to the laravel 4 after spending some few months in Codeigniter, I went through the lots of tutorials about laravel and one thing I want to be clear is what is the actual difference between Routes and Controller in laravel, because we can create and generate view in both controller and routes too. Will anyone explain me in brief when to use routes and Controller in laravel? Because in other Framework we need routes to specify some particular URL's within the apps and Controller were used to do some real tasks but in laravel I didnt get the main concept of Routes except the routing mechanism?
In Laravel, you can totally skip controllers and do the task of performing business logic and generating the view in the routes.
E.g I have a link b2.com/getUsers so in routes.php I can write:
Route::get('/getUsers',function()
{
$users=User::all(); //select * from users
return View::make('allUsers')->with('users',$users);
}
So, here to serve the request b2.com/getUsers, we didn't use controller at all and you can very well do this for handling all requests in your application, both get and post.
But then, if your application is large and have 500+ url's with complex business logic then imagine putting everything in one routes.php. It will totally make it criminally messy and whole purpose of architecture will be defeated. Hence what we usually do is, reserve routes.php for routing only and write all business logic (along with generation of views inside controllers)
So the same example can be solved as:
To handle link: b2.com/getUsers, in routes.php
Route::get('/getUsers', array('before' => 'auth', 'uses' => 'MyController#getUsers'));
MyController has the method getUsers defined like this:
public function getUsers()
{
$users=User::all(); //select * from users
return View::make('allUsers')->with('users',$users);
}
I usually create a controller for related activities e.g for login/signup/logout. I create AuthController and all the links related to those activities are routed to AuthController through routes.php.
The fact that you can get views or do a lot of things in Routes::any() is against MVC and separation of logic.
In Route::get("admin", function(){}), you indeed have a fast access to your route callback, which otherwise in a standard fashion must just be bound to controller. But Laravel allows you to do your job there in a closure (function(){}), instead of binding it to a controller. Anyway, it lets you, but you'd better avoid it. In Route::get() you only should go with your 'routing' and nothing more.
There is no reason for you to use callbacks in Route unless for testing or some trivial requests. So, better to avoid this:
Route::get("admin", function(){
return View::make("admin_index");
});
And rather go with this:
Route::controller("admin", "AdminController");
And in your AdminController.php :
// I mean create a file named AdminController.php in controllers directory under app.
class AdminController extends Controller
{
function getIndex()
{
return View::make("admin_index");
}
}
Read more about Route::controller and restful controllers.
Some Notes:
Having the ability to add closures in your Routes allows you to make
complex decisions on Routes and have a powerful routing system.
These callbacks let you add conditions to your route.
Having Controller separated from you Routes makes you application
more extensible, less confusing and makes other coders more
comfortable in future.
It allows you to focus better on your problem and finding solution,
this physical separation is very important. Having View::make()
inside your Route stirs all problems into each other and makes up a
confusion for the coder.
Let's see what we have in both cases:
In CodeIgniter, a route is just pointing your request to a specific method of your controller:
$route['blog/joe'] = "blogs/users/34";
Here when you visit application.com/blog/joe, you will invoke the controller BlogsController, call the method users() and pass 34 as the first parameter. Nothing else. As they put it, a route in CI is just a one-to-one relationship between a URL string and its corresponding controller class/method.
Now, in Laravel, you have a lot of possibilities:
You can directly return a simple response
You can return a view
You can point the request to a specific controller and a method
You can write some logic in a closure and then decide what you want to do
You can add some additional functionality to them, like attaching filters, checking parameters upon a regex, give them separate names, etc., but this is the main functionality.
What's the reason for being able to do so much stuff? It gives you the power to use them in any way you need. Examples:
Need a small website, rendering static HTML? Use them like this:
Route::get('/', function()
{
return View::make('greeting');
});
Need a bigger application using the traditional MVC pattern? Use like this:
Route::get('user/{id}', 'UserController#showProfile');
Need a RESTful approach? No problem. This will generate routes for all the CRUD methods:
Route::resource('photo', 'PhotoController');
Need something quick and dirty to handle a specific Ajax request? Keep it simple:
Route::post('foo/bar', function()
{
return 'Hello World';
});
TL;DR: For very simple things without or with very little logic, use them instead of controllers. Otherwise, always stick to the MVC principles and route to your controllers, so that they're the ones who do the actual work.
