QUESTION
I want to dispatch an event from my controller in cakephp2.10. Therefore I need to register the event listener for the controller. It is simple to achieve this when the event is emitted from my model, but I cannot figure it out for my controller. From the book: https://book.cakephp.org/2/en/core-libraries/events.html#global-event-manager:
...ANSWER
Answered 2021-Feb-04 at 14:13You should never manually instantiate a controller (except for maybe in unit tests), if you feel the need to do that, then this indicates a possible flaw in your application's architecture.
Unlike models, there can be only one controller involved per request (if there were more than one, this would again indicate an architectural flaw), so ideally there should be no reason for you to attach your listener to a specific controller instance.
I would go out on a limb and say that also if you have multiple controllers that dispatch that event, but you only want to listen to one of them, then that's again a possible architectural flaw, which could most likely be resolved by scoping the event properly in that specific controller, for example using a specific controller name like Controller.Test.myEvent. In your listener you could also check the subject whether it's a specific instance, but if the listener needs to know that much about the subject, then that's probably not good.
All that being said, yes, use the global event manager instead, it's the same principal as in the linked answer, for example:

QUESTION
We have the below contents on composer.json with dependencies and scripts. This comes from a legacy project where the vendors directory was pushed to GitHub. We're trying to remove that vendors directory from the repository to make its creation a part of the build process.
ANSWER
Answered 2020-Sep-29 at 19:06I copied your composer.json to my local environment and ran composer update and had the same results. The problem is, that the class Sensio\Bundle\DistributionBundle\Composer\ScriptHandler does not exist with your config. So I executed composer require sensio/distribution-bundle, but then I got a version conflict:

The last composer update completely broken my project based on Symfony5:
php.CRITICAL: Uncaught Error: Argument 1 passed to Sensio\Bundle\FrameworkExtraBundle\Request\ParamConverter\DoctrineParamConverter::__construct() must be an instance of Doctrine\Common\Persistence\ManagerRegistry or null, instance of Doctrine\Bundle\DoctrineBundle\Registry given
I've already updated all the references of Doctrine\Bundle\DoctrineBundle\Registry to Doctrine\Common\Persistence\ManagerRegistry a long time ago, according to the Symfony documentation
Any help would be appreciated

QUESTION
I'm having a really hard time to figure out what's happening when there is nothing being used to trigger re-render the component.
Events.js Component renders twice when I remove the useState() from the Event.js it renders once, but I need to keep it. when I use useEffect() inside Event components, renders fourth time.
I just kept the dummy data to give you to fill the emptiness and tried to remove React.memo, nothing happens. the problem is with the Event.js component I believe. I'm also using the Context API, but forth time rendering is too much.
useEffect inside App.js is getting some value from the localStorage, I can't access that direct 'cause the value is undefined by default

The Events.js file is located on /Pages/Events/Events.js
example code is below
Event.js ( child component )
...ANSWER
Answered 2020-Jun-08 at 09:39Well actually this is caused by your usage of React.memo, its second parameter is called areEqual, and you pass in () => false, so you are basically telling React that the props are always changing. Therefore whenever App rerenders, Events rerenders too.

ANSWER
Answered 2020-Jul-07 at 13:13So not sure how you're saving your meta_key in the first place? It looks like what you have is a serialized array with just a single, numerically indexed entry. So what you probably want to do is change wherever that's saved to just store the URL?
That said, you could access that meta value like this:
QUESTION
React memo isn't capturing the props neither the prevProps nor the nextProps and the component render well. The react docs say
- If your function component renders the same result given the same props, you can wrap it in a call to React.memo for a performance boost.
my problem is to stop twice rendering using react memo, but memo seems to be not working and the component renders twice with the same props.
The component renders when the Create New Event is clicked on /events
Child Component located at
/components/Event/CreateEvent/CreateEvent.jsthe parent component is located at
/Pages/Event/Event.jsline number999' from where the child component is being triggered
Here is the Code:
...ANSWER
Answered 2020-Jun-09 at 06:48In your example, you don't have an additional render for React.memo to work.
According to your render logic, there aren't any nextProps, you unmount the component with conditional rendering (creating).

Install event-manager
PHP requires the Visual C runtime (CRT). The Microsoft Visual C++ Redistributable for Visual Studio 2019 is suitable for all these PHP versions, see visualstudio.microsoft.com. You MUST download the x86 CRT for PHP x86 builds and the x64 CRT for PHP x64 builds. The CRT installer supports the /quiet and /norestart command-line switches, so you can also script it.
