I get the following error when running:
class page_generator extends Page_SchemaGenerator {
}
Application Error: requires jQuery or jUI support
BaseException, code: 0
C:\projects\wamp\atk4\atk4\lib\Form\Submit.php:33
Where did you get such class? What version of ATK4 are you using?
Anyway, you have to add jUI class iun your Frontend class.
Sorry, but I couldn't remain silent and will say that - schema generators are evil !!! :)
There are only very rare case when they are OK. One of such cases is if you actually require dynamically changeable DB structure. If that's the case, then better use this add-on: https://github.com/atk4/atk4-addons/tree/master/dynamic_model
Add the following to your lib/Frontend.php
$this->add('jUI');
And as #DarkSide said - schema generators are evil.
There is also on-the-fly generator controller for model:

I inherited a project that was created with Yii2, ver. 2.0.4, with the task to update said project to a more current version of Yii2 (2.0.15) because of the incompatibility of the older one with PHP 7.2+.
I noticed that there is a lot of use of assigning arrays to a model:
$model->_attributes = $array;
With the new version this results in an exception
'yii\base\UnknownPropertyException' with message 'Setting unknown property: app\models\model::_attributes'
For the time being I created a workaround with the following function:
function customSetAttributes(&$model, $array) {
foreach($model->attributeLabels() as $model_key => $model_label) {
if(!isset($array[$model_key])) continue;
$model->$model_key = $array[$model_key];
}
}
Also, the getter function now has a similar issue.
What I would like to know:
Was this type of assignment never intended in the first place (and I just haven't found the previous developer's code that enables it)? I skimmed over the Yii2 changelog but didn't notice anything related.
Is there a way to "salvage" the previous behaviour so I don't have to replace each occurence with my workaround function?
ActiveRecord::$_attributes was always private and never should be used in this way. I guess that previous developer edited framework core files in vendor directory and make this property protected/public.
You may try to emulate this behavior by creating virtual attribute using getter and setter:
public function get_attributes() {
return $this->getAttributes();
}
public function set_attributes($values) {
$this->setAttributes($values, false);
}
But this will not always work and it is more like an ugly hack to make crappy code work. I strongly suggest to fix code to use setAttributes() instead of _attributes.
Also you should compare yii2 package from vendor directory with source from https://github.com/yiisoft/yii2-framework/releases/tag/2.0.4 - you may find more places where core was edited.
I'm in the process of trying to make a laravel compatible composer/packagist package. I'm using Laravel 5.5.
I've created a package : floor9design/machine-identifier. Composer downloads this to vendors/floor9design fine, but despite reading/googling how to do this, I'm unsure of how to include this in my laravel projects.
PHP Storm is correctly picking up the class, auto-completing as expecting.
I have not modified any files so far. If I add the following to a controller:
use Floor9design\MachineIdentifier\MachineIdentifier;
(alongside some class usage on the page).
PHP storm autocompletes this (as it does with other classes validly called).
When I try to load this, the following error comes:
Class 'Floor9design\MachineIdentifier\MachineIdentifier' not found
I've had a look round plenty of tutorials, and this final step seems to be missing from a lot of information.
I realise there are three approaches:
Firstly:
Direct include_once, which while working, is not the normal approach
Secondly:
Pre-laravel 5.5 approach (add something to app.php)
Thirdly
Laravel 5.5 approach and up, autodetection of something.
I've deliberately said something as the documentation seems to speak about ServiceProviders, and I simply don't get how they work.
Let me rephrase this into a question and a follow up question:
Question: apart from include_once, how do I load the MachineIdentifer class from floor9design/machine-identifier in Laravel.
Question 2: If the answer is via a service provider, can you simply explain how they relate to one another.
Thanks
Answer (as accepted below)
On the composer repo I was incorrectly specifying the PSR4 namespace, which is now corrected to:
"autoload": {
"psr-4": {
"Floor9design\\MachineIdentifier\\": "src"
}
}
The previous namespace had a -, which is an illegal character. Many thanks to lawrence-cherone.
Your PSR4 is wrong in the package
floor9design\\machine-identifier\\": "src"
Will cause the composer/autoload_psr4.php to map to:
'floor9design\\machine-identifier\\' => array($vendorDir . '/floor9design/machine-identifier/src'),
Which is not a valid class namespace.
You should change the PSR4 to match your class namespace:
Floor9design\\MachineIdentifier\\": "src"
Once you fix that you will be able to use it like normal from anywhere in your project.
We have used Zend_Log, which is configured in application.ini differently for different circumstances. We initialize it/get it in the bootstrap and store it in the registry:
$r = $this->getPluginResource('log');
$logger = $r->getLog();
But we've subclassed Zend_Log (say, Our_Log) to add customized features, and want to get it the same way. So then we have to make a new Resource Plugin. That seems quite easy - just copy Application/Resource/Log.php, rename the file to Ourlog.php, rename the class to class Zend_Application_Resource_Ourlog. For now, let's not worry about "Our_Log", the class -- just use the new Resource Plugin to get a Zend_Log, to reduce the variables.
So then, our new code in the bootstrap is:
$r = $this->getPluginResource('ourlog');
$logger = $r->getLog();
but of course this doesn't work, error applying method to non-object "r". According to the documentation,
"As long as you register the prefix path for this resource plugin, you
can then use it in your application."
but how do you register a prefix path? That would have been helpful. But that shouldn't matter, I used the same prefix path as the default, and I know the file is being read because I "require" it.
Anyway, any guidance on what simple step I'm missing would be greatly appreciated.
Thanks for the pointers -- so close, so close (I think). I thought I was getting it...
Okay, so I renamed the class Xyz_Resource_Xyzlog, I put it in library/Xyz/Resource/Xyzlog.php
Then, because I don't love ini files, in the bootstrap I put:
$loader=$this->getPluginLoader();
$loader->addPrefixPath('Xyz_Resource','Xyz/Resource/');
$r = $this->getPluginResource('xyzlog');
if (!is_object($r)) die ('Not an object!!');
Sudden Death. So, okay, do the ini:
pluginPaths.Xyz_Resource='Xyz/Resource/'
The same. No help. I believed that the basepaths of the plugin paths would include the PHP "include" paths. Am I mistaken in that? Any other ideas? I'll happily write up what finally works for me to help some other poor soul in this circumstance. Something to do with Name Spaces, maybe?
Plugin classes are resolved using the plugin loader, which works slightly differently to the autoloader; so just requiring the class in doesn't help you here. Instead, add this to your application.ini:
pluginPaths.Application_Resource = "Application/Resource"
you should then be able to use the class as normal. Since your path above will be checked before the default Zend one, you can also name your class 'Log' and still extend the Logger resource to override the standard functionality.
I'm used to Zend Framework, when you write your own component, you make it's own Exception file, but on per file basis, then you have such structure:
Zend/View/Exception.php
Zend/View/Helper/Exception.php
Zend/View/Renderer/Exception.php
etc.
I'm ok with, I also use Doctrine2 and Exception are "stored" in a different way
something like (in a Zend way)
and in Zend/View/Exception.php
class Exception {
public static function invalidArguement() {
return new self('Invalid arguement was given, etc..');
}
I understand that the second approach is less flexible but more accurate because it throws exception according the error.
The first approach is just a way to be able to throw a Zend_View_Exception with a custom messagE.
Also, what about one Exception file per, Exception.
Like the following structure :
Exception/InvalidArguement.php
Exception/AuthentificationFailed.php
Exception/QuantityLimit.php
Is there any best practices? Any pros/cons?
For me the best practice is to group exceptions related to their issue.
For example if you have a number of Auth exceptions, like InvalidDetails, UserNotFound put them here
Library/Auth/Exceptions/InvalidDetails.php
Library/Auth/Exceptions/UserNotFound.php
Each exception should be an extension of Zend_Exception ( unless you've extended it yourself )
this way you can do:
throw new Library_Auth_Exception_InvalidDetails("Invalid details when trying to login");
the benefit of using this method is you DONT need to have a message, the Exception name can cover it enough.
My assumptions here is you setup a namespace for Library called Library and everything is within there.
I tend to group everything, so a typical Auth library could be:
Auth/Forms/Login.php
Auth/Exception/InvalidUser.php
Auth/Orm/Abstract.php
Auth/Orm/Doctrine.php
HTH
I've never worked with Zend framework but if this at all helps, I would at least make a common Exception class and all those other ones extend that rather than just make one for each.
I am trying to use Searchable Behaviour hosted here: http://code.google.com/p/searchable-behaviour-for-cakephp/
To initialize the search_index table with existing data, I have used this: http://code.google.com/p/searchable-behaviour-for-cakephp/issues/detail?id=1&q=controller Reply No. 2 which creates the class SearchController.
The code was working fine on my local test server which runs PHP5.
However, the server has PHP 4 and when I tried the code on server it gives this error:
Fatal error: Cannot redeclare class searchcontroller in LONG_PATH/cake/app/models/behaviors/searchable.php on line 2
Does it really has to do something with the PHP version or have I done some logical mistake?
Not sure, but you could try my Searchable plugin instead
I just changed the name of the search Initialization controller and it worked. Looks like there is a Search Class created with Searchable behaviour.
Also, while using searchable plugin for CakePHP 4.x.x, if html_entity_decode and iconv are giving problems(as they did to me), use ut8_decode for decoding in place of html_en... and just comment out the iconv. The result may look ugly, but it works for most cases.
