I'm having problems with my child twig templates properly resolving their assets.
My assets lie in web/bundles/mlbp/images|js|css
In my parent twig template that all my other templates inherit from I have something like:
{% block javascripts %}
<script src="{{ asset('bundles/mlbp/js/jQuery.js') }}" type="text/javascript"></script>
{% endblock %}
When looking at source this resolves properly to /bundles/mlbp/js/jQuery.js
But in one of my child templates I'm doing something like this:
{% block javascripts %}
{{parent()}}
<script src="{{ asset('bundles/mlbp/js/tableSortInit.js') }}" type="text/javascript"></script>
{% endblock %}
This for some reason resolves to /js/tableSortInit.js which does not exist. I don't see why it would work in one but not the other so any help will be very appreciated
You should try checking any other templates that relate to that one, it may be coming from those especially if you do a lot of in template rendering etc.

Is this possible to use assetic with inheritance ? With the code below I get this error :
An exception has been thrown during the rendering of a template ("Unable to generate a URL for the named route "_assetic_41351d9" as such route does not exist.
My app layout :
{# app/Resources/views/layout.html.twig
{% block javascripts %}
{% javascripts
'assets/js/jquery-2.2.0.min.js'
'assets/js/main.js'
output='assets/compiled/app.js'
%}
<script src="{{ asset_url }}"></script>
{% endjavascripts %}
{% endblock %}
My child layout :
{% extends "::layout.html.twig" %}
...
{% block javascripts %}
{{ parent() }}
{% javascripts
'assets/js/jquery.owl.min.js'
output='assets/compiled/page.js'
%}
<script src="{{ asset_url }}"></script>
{% endjavascripts %}
{% endblock %}
Yes you can use inheritance with Twig, and there is nothing inherently wrong with what you are trying to do in your code. I would try completely clearing your cache and loading the page again, and make sure all of the assets you are trying to load properly exist.
I believe it's not working the way we wanted it, but I discovered named assets
You name all your parent template assets in the config file
assetic:
assets:
jquery_and_ui:
inputs:
- '#AppBundle/Resources/public/js/thirdparty/jquery.js'
- '#AppBundle/Resources/public/js/thirdparty/jquery.ui.js'
And then you include the jquery_and_ui name in all children, along with any other assets:
{% javascripts
'#jquery_and_ui'
'#AppBundle/Resources/public/js/*' %}
<script src="{{ asset_url }}"></script>
{% endjavascripts %}
It's obviously a hassle to do but I can't find the easy way to do this and don't understand why it doesn't generate parent template assets.
EDIT
Are you by any chance using LiipThemeBundle? This could solve the problem:
# app/config/config.yml
liip_theme:
# ...
assetic_integration: true
That should work fine. Extending block javascripts is ok for assets as well.
Actually such a message
Unable to generate a URL for the named route "_assetic_41351d9" as
such route does not exist
says about outdated cache. Did you clear it? That helped me.
php app/console cache:clear --env=dev
Hope it makes sense.
In my case it appeared that error was caused by fact that the base file extension was .html.twig, while child file had only .twig - changing extensions of both files to .html.twig solved the problem...
I just run on Gassetics, seems to be the next gen of SF assets management. So far I used Assetics.
One question though : with Assetics I used to split files in order to load only needed one, using Twig parent() method :
{% block scripts %}
{{ parent() }}
{% javascripts
'#LCHAdminBundle/Resources/public/js/jquery.specific.addition.js'
%}
<script src="{{ asset_url }}"></script>
{% endjavascripts %}
{% endblock scripts %}
SO I could add on a specific page, only script needed and so was "forced" (in the noble way) to think and split my twig files accordingly.
Is it possible to do so with Gassetics? I jsut saw that you can specify back-end and front-end files, nothing more.
If I nest Twig files with Gassetic tag, will it do the trick?
EDIT : thanks to Wouter J. comment, I adjust my question :
In Assetics you explicitely specify files you want to include, giving the nesting ability. As in Gassetics you just add the tag which will be replaced during CSS/JS file generation, how do you achieve the same?
You can do all of this in the gassetic config (see section yaml example with gassetic.yml in https://github.com/romanschejbal/gassetic).
Example gassetic.yml:
js:
files:
common.js:
- assets/vendor/jquery/jquery.js
- assets/vendor/angular/angular.js
page1.js:
- assets/vendor/lchadminbundle/jquery.specific.addition.js
common.html.twig:
{% block scripts %}
<!-- prod:common.js --><!-- endbuild -->
{% endblock scripts %}
page1.html.twig
{% extends 'common.html.twig' %}
{% block scripts %}
{{ parent() }}
<!-- prod:page1.js --><!-- endbuild -->
{% endblock scripts %}
This approach is better than nesting scripts in children templates, since the commonly needed files can be cached between page requests.
I have a one-page webapp written with Symfony 2 where all css and javascript assets sit in web/static/all.js and web/static/all.js. These a linked from the intex.html.twig template in a standard way:
{% javascripts output='static/all.js' filter="?closure"
'#MyBundle/Resources/assets/vendor/jquery/jquery.js'
'#MyBundle/Resources/assets/...'
'#MyBundle/Resources/assets/...'
%}
<script type="text/javascript" src="{{ asset_url }}"></script>
{% endjavascripts %}
{% stylesheets output='staic/all.css' filter="?yui_css" combine=true
'#MyBundle/Resources/assets/css/reset.css'
'#MyBundle/Resources/assets/css/...'
'#MyBundle/Resources/assets/css/...'
%}
<link rel="stylesheet" href="{{ asset_url }}" type="text/css" media="all" />
{% endstylesheets %}
This is pretty cool already, because the browser only has to do 3 requests during the first launch and 1 or 0 requests later (all.css and all.js are cached using .htaccess).
But I want to go further and just dump all css and js into index.html similar to what google does on their homepage. This will result only one http request during the first run, which will speed up the app a little. It would be ideal to have a flag that I pass to the template or keep in twig globals that will enable switching between two modes on demand.
{%if dumpAssetsIntoTemplate %}
{# all js and css here #}
{% else %}
{# asset urls #}
{% endif %}
How could this be done with minimum pain?
If you look at Twig reference about Twig extensions you can see that the render function takes a path or a URL.
{{ render(path('route', {params})) }}
{{ render(url('route', {params})) }}
Quoting the usage from the doc "This will render the fragment for the given controller or URL".
So I would try that:
<style type="text/css">
{% stylesheets output='static/all.css' filter="?yui_css" combine=true
'#MyBundle/Resources/assets/css/reset.css'
'#MyBundle/Resources/assets/css/...'
'#MyBundle/Resources/assets/css/...'
%}
{{ render(asset_url) }}"
{% endstylesheets %}
</style>
Same approach with your Javascript files.
If it doesn't work, you'll probably want to tweak the settings of the Assetic bundle in particular the setting named use_controller.
I am new to Symfony 2. Previously I worked a lot with Codeigniter. Now that I am exploring assetic, I am not able to understand how I can add a single file to the stack of JS files which are already being loaded.
I have a main page twig file which has something like this:
{% javascripts '#BlogBlogBundle/Resources/public/js/vendor/*' output='js/combined.js' %}
<script type="text/javascript" src="{{ asset_url }}"></script>
{% endjavascripts %}
Now this works fine if all the JS files are inside the vendor folder. But what if I have a JS file contact.js inside a folder called contact and I want that to be visible only on contact page. So, when I added such a code inside block body of contact page twig file
{% javascripts '#BlogBlogBundle/Resources/public/js/home/*' output='js/home_combined.js' %}
<script type="text/javascript" src="{{ asset_url }}"></script>
{% endjavascripts %}
the contact.js is coming before all other js files which are being loaded before the body ends.
In codeigniter, using the Carabiner library I could set up the default files which I want to load on all pages like jQuery. And if there are any specific file for a page, I can do that inside that particular controller.
Please let me know how I can do this inside Symfony also.
You can add a file to your assets like this:
{% javascripts
'#YourBundle/Resources/public/js/*'
'#AnotherBundle/Resources/public/js/some.js'
'#YourBundle/Resources/public/vendor/someother.js'
output="filename.js"
%}
<script src="{{ asset_url }}"></script>
{% endjavascripts %}
In order to have pre-defined asset collections which you can then use as for example '#js_default' you can add these in your assetic.assets configuration as suggested in my answer here.
To add the contact.js after the main file js files you can do something like this.
{% block javascripts %}
{{- parent() -}}
{% javascripts "#AcmeBundle/Resources/public/js/contact.js" %}
<script type="text/javascript" src="{{ asset_url }}" ></script>
{% endjavascripts %}
{% endblock %}
I'm including CSS stylesheets in my template like so:
{% stylesheets
"#SomeBundle/Resources/assets/css/default.css.twig"
"#SomeBundle/Resources/assets/css/global.css.twig"
%}
<link rel="stylesheet" href="{{ asset_url }}" />
{% endstylesheets %}
However I want to run these CSS files through Twig, is this in any way possible while using the {% stylesheets %} tag or does this require some other approach. I've already tried enabling a twig filter but that does not exist.
You could do it if you load the css as an internal stylesheet. Something like this:
{% block stylesheets %}
{{ parent() }}
{% include 'AcmeBundle:Bundle:mycss.css.twig' %}
{% endblock %}
And then the mycss.css.twig template would contain:
<style type="text/css">
/* */
</style>
Most common things you'd want to do by processing CSS with Twig should be possible with Sass, LESS or similar, which can be applied as Assetic filters. First tutorial Google threw up was this one: http://alexandre-salome.fr/blog/Sass-Compass-Assetic-In-Ten-Minutes
Admittedly, that doesn't look like much help if you're unable to run Ruby/Node.js/whatever on the production server you're developing for, but it should be possible to create an Assetic filter based on one of the PHP ports of Sass/LESS (assuming they're any good) if that's the case.
