isEmpty in JavaScript

The best way to check if an object is empty is by using a utility function like the one below. function isEmpty(obj) { for(var key in obj) { if(obj.hasOwnProperty(key)) return false; } return true; } So if you have an empty object, you can check whether it is empty by using the above function. var myObj = {}; // Empty Object if(isEmpty(myObj)) { // Object is empty (Would return true in this example) } else { // Object is NOT empty }

Check One Checkbox for all

function checkOneForAll(ele, main) { var checkAll = 1; $('input' + ele).each(function () { if ($(this).prop("checked") === false) { checkAll = 0; $('input' + main).prop("checked", false); return false; } else { checkAll = 1; } }); if (checkAll === 1) { $('input' + main).prop("checked", true); } }

Create Bundle In Symfony 3.3.*

composer create-project symfony/framework-standard-edition s334 "3.3.4"
bin/console generate:bundle
Share across multiple apps: yes
namespace: Paul\ArtBundle
bundle name: PaulArtBundle
Target Directory: src/


Refreshed the browser and sure enough I got the class not found message.

The generate:bundle command is not updating the autload section of composer.json when a new namespace is introduced. Edit composer.json and:


# composer.json
"autoload": {
    "psr-4": {
        "AppBundle\\": "src/AppBundle",
        "Paul\\": "src/Paul"
    },
    "classmap": [ "app/AppKernel.php", "app/AppCache.php" ]
},


Then run


composer dumpautoload


And restart the server(maybe). That should fix the bundle class not found problem.

I have not used the generate:bundle command is quite some time ever since the standard was to put everything under AppBundle so I don't know how long this has been "broken". But at least three questions in the last week or so indicates it was something recent.

And by the way, when I refreshed the browser I got "Hello World" which threw me for a bit. Turns out the new bundle overrides the / route which is also sort of special.

And in case anybody is wondering why this started happening, Symfony 3.2 changed from


#composer.json
"psr-4": { "": "src/" },
To
"psr-4": { "AppBundle\\": "src/AppBundle" },


You could always just change it back though I think spelling out individual namespaces might be "better". Not sure.

And here is an issue with more details: https://github.com/symfony/symfony-standard/issues/1098

Looks like the maintainer favored a tiny speed improvement over breaking an existing command. Oh well. Symfony Flex is supposed to make everything great again
