I've having trouble passing off an object to my 'edit' view in Laravel 4. The URL is generated correctly "localhost/edit/1" however this is the returned error:
Some manadatory parameters are missing ("offer") to generate a URL for route "get edit/{offer}
My related routes.php snippet:
Route::get('edit/{offer}','OfferController#edit');
The OfferController#edit action:
public function edit(Offer $offer)
{
return View::make('edit',compact('offer'));
}
Just some extra detail, here's the snippet from the 'index' view that initiates the action:
Edit
I should also mention when I remove the Blade form in '/views/edit.blade.php' the view is created, including the header which specifies the $offer->id:
<h1>Edit Offer {{ $offer->id }}</h1>
What am I missing here?
You need to pass an array to action():
Edit
Your Edit function needs to be changed. You are passing id in link, but expects Instance of Offer in edit function. Assuming Offer is an Eloquent model,
public function edit($id)
{
$offer = Offer::find($id);
return View::make('edit',compact('offer'));
}
Hope this helps.

I'm trying to change my ways in Laravel, but I find it quite frustrating
Normally, in a controller I'd write something like this
public function edit($id) {
$question = Question::findOrFail($id);
return view('question.edit', compact('question');
}
This obviously works. In the HTML the route that calls this is {{ route('question.edit', $question->id) }}. Now I want to use the method it is written by Artisan when you create the controller. If I do:
public function edit(Question $question) {
return view('question.edit', compact('question');
}
This doesn't work (of course I'm changing the blade directive to {{ route('question.edit', $question) }}), this always passes an empty Question model, it doesn't have id or any of the other fields that were accessible in the blade file. If I do a dd() in the blade file, it'll show the correct model, when passed to the Controller is empty.
What am I doing wrong?
You need to match your type hinted variable name to the name of the route parameter if you want Implicit Model Binding to work, otherwise you are just asking for a dependency and it will inject a new instance of that model:
// vvvvvvvv
Route::get('question/{question}/edit', 'YourController#edit');
// vvvvvvvv
public function edit(Question $question)
I'm trying to call controller with href, but I'm getting error, I need pass a parameter.
Im doing like this
<i class="material-icons" title="Delete"></i>
Controller Code
public function destroy(Story $story)
{
$story = Story::find($id);
$story->delete();
return redirect('/stories')->with('success', 'Historic Removed');
}
Error Missing required parameters for Route: stories.destroy -> error
The link_to_action() helper generates an actual HTML link, which is an <a> tag. You're therefore already using it wrong.
However the error you're getting is likely not related to this.
The best way to link to routes is using the route() helper:
link
And the route definition:
Route::get('/someroute/{:param}', ['uses' => 'IndexController#index', 'as' => 'index.index']);
Note the as key, it assigns a name to this route. You can also call
Route::get(...)->name('index.index')
which yields the same result.
I might be wrong but in html you're passing an integer, in controller though, function is expecting an object of Story. Just change Story story to $id and it should be good.
Anyway, can't say much more without actual error.
Since you are accepting $story as model object so you don't have to use Story::find() and also you haven't define $id in your destroy method therefor Change your code to:
public function destroy(Story $story)
{
$story->delete();
return redirect('/stories')->with('success', 'Historic Removed');
}
Hope it helps.
Thanks
You should use it in this way: since according laravel explanation for function link_to_action first param will be controller function path, 2nd will be name and 3rd will be array of required params:
<i class="material-icons" title="Delete"></i>

I want to pass a object from the blade file to the controller file. The purpose is when the user click an edit button the user will get a form which is filled with the previous input data. I am using this code in the blade file:
Edit
But When I want to get the passed object from the controller's edit method I get a null. My Controller code is like this now:
public function edit(FeesType $feesType)
{
//
dump($feesType->name);
return view('feestype.edit',['feesType'=>$feesType]);
}
Here I have dump the $feesType object but I get a null. Please help me how can I solve this problem.
Thanks in advance
Route model binding works a bit different here is the documentation
What you need to do is have your route like this:
Route::get('feestype/{feesType}/edit', 'YourController#edit')->name('feestype.edit');
then in your view
Edit
-- EDIT
using a resource file:
Route::resource('feestype', 'YourController')
the link will be built the same as above:
{{ route('feestype.edit', $feesType) }}
you should change your Route to :
Route::put('feestype/{id}/edit', 'YourController#edit');
For update and edit you should use put not get.
Note that for this code:
Edit
first you should compact $feestype in YourController then use your code in blade.
Now the code in the blade file is
Edit
The controller file contains this code:
public function edit(FeesType $feesType)
{
//
$feesType = FeesType::find($feesType->id);
dump($feesType->name);
return view('feestype.edit',['feesType'=>$feesType]);
}
And here is my Route definition:
Route::resource('feestype','FeesTypesController');
And the browser shows this message:
I have a problemwith my routes. When I call 'editPolicy' I dont know what execute but is not method editPolicy. I think I have got problem beteweeb this two routes:
My web.php ##
Route::get('admin/edit/{user_id}', 'PolicyController#listPolicy')->name('listPolicy');
Route::put('/admin/edit/{policy_id}','PolicyController#editPolicy')->name('editPolicy');
I call listPolicy route in all.blade.php view like this:
{{ $user->name }}
And call editPolicy route in edit.blade.php view like this:
Remove</td>
My PolicyController.php is:
public function listPolicy($user_id)
{
$policies = Policy::where('user_id', $user_id)->get();
return view('admin/edit',compact('policies'));
}
public function editPolicy($policy_id)
{
dd($policy_id);
}
But I dont know what happend when I call editPolicy route but editPolicy method not executing.
Any help please?
Best regards
Clicking an anchor will always trigger a GET request.
route('listPolicy', $user->id) and route('editPolicy', $policy->id) will both return admin/edit/{an_id} so when you click your anchor, listPolicy will be executed. If you want to call editPolicy, you have to send a PUT request via a form, as defined when you declared your route with Route::put.
Quick note, your two routes have the same URL but seem to do very different things, you should differentiate them to avoid disarray. It's ok to have multiple routes with the same url if they have an impact on the same resource and different methods. For example for showing, deleting or updating the same resource.
Have a look at the documentation.
I have a Data model that I want people to be able to view individual records of and then edit/add data to. I have managed to get the view route working;
Route::get('/data/{data_token}', 'DataController#show');
Data_token, is a unique string. This then uses this DataController function;
Public function show($data) {
$data = Data::where('data_token',$data)->first();
return view('data.show', compact('data'))
}
After which I can display the data on the page, and have a form for editing (actually its for adding data that doesn't exist, but whatever, same principle right).
On the form on the data.show view, I am sending it to a different view;
Route::get('/data/{data_token}/edit', 'DataController#edit');
This can use the $request variable to return the forms values, but I can't relate it to the data row I was previously editing?
how do I get the {data_token} passed to the edit function of the controller?
Edit( adding route files)
Noticed I forgot the {'data_token'} in the post route.
/Begs forgiveness
I think you've misunderstood how the routes and controllers work. What you're looking at is a fairly simple CRUD setup like the following;
Route::get('/data/{data_token}', 'DataController#show');
Route::get('/data/{data_token}/edit', 'DataController#edit');
Route::post('/data/{data_token}/edit', 'DataController#update');
Now your controller would have;
public function show($dataToken) { ... }
public function edit($dataToken) { ... }
public function update($dataToken, Request $request) { ... }
Then you'd have your form on the edit view like so;
<form action="{{ route('DataController#update') }}" method="post">
Laravels router will always try to pass in the URI variables as arguments to the methods provided.
Providing that I have understood what you need, this should suffice.
