django cms picture resize - django-cms

I'm freshly new with Django CMS. I'm able to resize something by CSS in Django but that process slows me down so I think it would be faster by using Django CMS. Ok now I got the Welcome page with Django CMS, then I start by adding a picture and surprised that there is not an option to resize it. I found something like sorl_thumbnail package but can't figure out how to integrate the code to my template. Here is from the tutorial of sorl_thumbnail:
{% load thumbnail %}
{% thumbnail item.image "100x100" crop="center" as im %}
<img src="{{ im.url }}" width="{{ im.width }}" height="{{ im.height }}">
{% endthumbnail %}
In my feature.html template:
{% extends "base.html" %}
{% load cms_tags staticfiles sekizai_tags menu_tags %}
{% block content %}
<div>
{% placeholder "feature" %}
</div>
<div>
{% placeholder "content" %}
</div>
{% endblock content %}
The tutorial of sorl_thumbnail is useless, it doesn't say where to put their code. I tried to paste the whole thing but no luck. Can you guys help please!

djangocms-picture plugin is rather basic, please check cmsplugin-filer (https://pypi.python.org/pypi/cmsplugin-filer/0.10) plugins for more advanced image plugin

I would also recommend cmsplugin_filer_image as mentioned by #yakky
See: https://github.com/stefanfoulis/cmsplugin-filer/tree/develop/cmsplugin_filer_image
But if you want to continue use djangocms-picture, you'll need to override the plugin template.
Copy the snippet below to cms/plugins/picture.html in your template directory.
{% load thumbnail %}
<span class="plugin_picture{% if picture.float %} align-{{ picture.float }}{% endif %}">
{% if link %}<a href="{{ link }}">{% endif %}
{% thumbnail picture.image "100x100" crop="center" as im %}
<img src="{{ im.url }}" width="{{ im.width }}" height="{{ im.height }}">
{% endthumbnail %}
{% if link %}</a>{% endif %}
</span>

Reuseable blocks inside of custom form themes in symfony

I want to call a custom block inside an overwritten theme-block:
{% block file_widget %}
{% if image is not null %}
{{ block('imagePreview') }}
{% endif %}
{{ block('form_widget') }}
{% endblock %}
{% block imagePreview %}
<img src="{{ image.getFullPath | imagine_filter('medium_square') }}"
alt="{{ image.filename }}"/>
{% endblock %}
The imagePreview is not shown.
But it is working when I don't use a block.
And it is also working when I dont use a FormTypeExtension and create an ImageType instead.
So I guess the file_widgetblock still has the scope of the parent form_div_layout.html.twig and there in fact no imagePreview block exists.
So how can I solve this.
I mean now I solved it by removing the block.
But I just want to know if someone has a solution to this.
Maybe there is a way for using reuseable blocks inside of custom form themes in symfony?
Finally I found the solution:
I just did not 'use' the base template explicit.
The form theme worked without this - because symfony falls back the the base form theme when it does not find a block inside the new theme file.
But it seems then you also can not use custom blocks inside this new theme file.
So this works now:
{% use 'form_div_layout.html.twig' %}
{% block file_widget %}
{% if image is not null %}
{{ block('imagePreview') }}
{% endif %}
{{ block('form_widget') }}
{% endblock %}
{% block imagePreview %}
<img src="{{ image.getFullPath | imagine_filter('medium_square') }}"
alt="{{ image.filename }}"/>
{% endblock %}

How to change CSS properties from within django HTML template logic

Newbie question I presume: How do I change some CSS property (// change background image of parent div) of the parent element from within the logic in the HTML template? Do I really need to implement JS for this?
<div class="exercise-items-wrapper">
{% if error %}
{{ error }}
{% else %}
{% for x in exercise %}
<div class="exercise-item">
{{x.name}}
{% if x.primary_focus == 'CO' %}
// change background image of parent div
{% endif %}
{% if x.friend_verified %}
<img src="{% static 'main/images/fv.svg' %}" height="14px">
{% endif %}
<p id="exercise-level" class="exercise-level">lv. VII</p>
{% if x.video_verified %}
<img src="{% static 'main/images/vv.svg' %}" height="14px">
{% endif %}
</div>
{% endfor %}
{% endif %}
</div>
If by parent div you're referring to the div with class exercise-item, then the way I've always done this is to simply also write the if-then template block within the class attribute:
<div class="exercise-item {% if x.primary_focus == 'CO' %}special-background-class{% endif %}">
And then define special-background-class in your CSS. Admittedly it doesn't look nice to read, but it works and it's much more maintainable than anything that has to use JS, unless your JS is already well-integrated into your Django app.

Django: How to import CSS libraries in Ajax template

I am using Ajax in my Django project to implement some simple searching. In my template folder, I have created an html file called "ajax_search.html" where I write how I want my objects to be displayed on a page. Right now it looks like this:
{% if puzzles.count > 0 %}
{% for puzzle in puzzles %}
<a href="{% url 'puzzle' puzzleID=puzzle.id %}">
{{puzzle.title}}
</a>
<br>
{% endfor %}
{% elif search_len < 3 %}
{% else %}
No puzzles match the search
{% endif %}
This works fine, but I wanted to style it to look better. Is there any way I could import some CSS into this template?
Thank you!

Symfony2 Twig: embedding a template - Where to put JS

On some of my pages I want to embed a toolbar with some generic functionality like sharing, reporting and bookmarking. Currently I do it like this
{# page-detail.html.twig #}
{% extends 'layout.responsive.html.twig' %}
{% block content %}
{% include "toolbar/index.html.twig" with {'foo':'bar'} %}
{# further content... #}
{% endblock %}
As the features of the toolbar require some information about the context it's embedded in, I pass this information in the with-clause. So far so good.
Now, all the buttons are invoking some JavaScript on clicking. Modal windows are popping up, dialogs are displayed, etc. I would like to put the related JS inside the toolbar template but here is the problem:
All my JS-libraries are loaded at the bottom of the page before the closing body-tag. Means, in my toolbar template I have no access to them.
So I thought of the following solutions which I am not really happy with:
move the inclusion of the JS-libraries to the top (loading js slows down page display, also JS would be scattered)
put the respective JS in the javascripts-block in "page-detail.html.twig" (toolbar code is separated from the template code and mixed with the JS-Code needed there)
use the "embed"-Tag and define a JS-Block in the toolbar-Template (won't help as I can access the blocks in the embedding parent template only within the "embed"-Tag)
use the "use"-Tag instead. Well that sounds best so far, however, Code would look like this (assuming toolbar-template defines the blocks "toolbar_content" and "toolbar_js"):
Code:
{# page-detail.html.twig #}
{% extends 'layout.responsive.html.twig' %}
{% use "toolbar/index.html.twig" %}
{% block content %}
{% block toolbar_content %}
{{ parent() }}
{% endblock %}
{# further content... #}
{% endblock %}
{% block javascripts %}
{{ parent() }}
{% block toolbar_js %}
{{ parent() }}
{% endblock %}
... local JS
{% endblock %}
Also in this solution I cannot pass the environment variables anymore using the "with"-clause as it is now used for resolving name-conflicts of the blocks.
I feel like I am missing something. How is it done right? It seems like such a common task.
Additional information
I think not essential for the question but for more clarity, here is how my layout template looks like (not complete just the relevant blocks).
{# layout.responsive.html.twig #}
{% block stylesheets %}
{# bootstrap.css, custom.css, ... #}
{% endblock %}
{% block content %}
{% endblock %}
{% block javascripts %}
{# jquery, bootstrap, ... #}
{% endblock %}
And my toolbar:
{# toolbar/index.html.twig #}
<div class="toolbar btn-toolbar" role="toolbar">
<div class="btn-group" role="group">
<button type="button" class="btn btn-default" data-toggle="modal" data-target="#report">Report</button>
</div>
<!-- more buttons -->
</div>

Unable to embed templates in Symfony2

I want to add some content in Symfony 2. I do it as follow:
{% embed "sub.html.twig" %}
{% block sourcecode %}
<div class="tab-pane" id="5" name="textsource">
<textarea id="source" class="span6"></textarea>
</div>
{% endblock %}
{% endembed %}
When I run this then it is showing that it is unable to find sub.html.twig. What should I do??
And in sub.html.twig I am using the following code:
{% embed 'AcmeTaskBundle:Default:index.html.twig' with {} %}
Please try to change
{% embed "sub.html.twig" %}
to
{% embed "AcmeTaskBundle:Default:sub.html.twig" %}
