Does anyone know how to resolve this error please? I have checked and the admin site is registered in the URLS file. In all the admin.py files the relevant models are all registered. I have moved django.contrib.auth to the top of my applications in settings.py. I have also dropped and re-created the default database.
Please note I use database routers

I am trying to learn to use encore webpack.
Well, following this guideEncore + webpack + bootstrap sass and this guide Symfony 4+ enconre + Bootstrap 4 I got symfony to use the scss and js assets I use.
But the problem is when I insert an image in my scss code (for a bg) the relative url I see in the browser is wrongly generated.
Webpack is generating the image here:
public\build\images\2.f26e9a05.jpg
But the url in the browser ends up like this:
/public/build/build/images/2.f26e9a05.jpg
(if I delete the second "build/" the image loads like it should)
this is my folder estructure:
assets:
css:
app.scss
js:
app.js
public:
images:
2.jpg
app.scss:
#import '~bootstrap/scss/bootstrap';
...
.parallax {
background-image: url("images/2.jpg");
}
Webpack.config.js:
var Encore = require('#symfony/webpack-encore');
Encore
// the project directory where compiled assets will be stored
.setOutputPath('public/build/')
// the public path used by the web server to access the previous directory
.setPublicPath('build')
// the public path you will use in Symfony's asset() function - e.g. asset('build/some_file.js')
.setManifestKeyPrefix('build/')
.cleanupOutputBeforeBuild()
.enableSourceMaps(!Encore.isProduction())
// the following line enables hashed filenames (e.g. app.abc123.css)
//.enableVersioning(Encore.isProduction())
// uncomment to define the assets of the project
.addEntry('app', './assets/js/app.js')
//.addStyleEntry('css/app', './assets/css/app.scss')
// uncomment if you use TypeScript
//.enableTypeScriptLoader()
// uncomment if you use Sass/SCSS files
.enableSassLoader()
// uncomment for legacy applications that require $/jQuery as a global variable
.autoProvidejQuery()
;
module.exports = Encore.getWebpackConfig();

I am responding to this rather old question, because I assume some things have changed in the meantime concerning yarn watch and the setting of the public path:
If I do a:
.setPublicPath('./')
yarn watch feels offended, and shows a:
WARNING The value passed to setPublicPath() should *usually* start with "/" or be a full URL (http://...). If you're not sure, then you should probably change your public path and make this message disappear..
So I think the way this is meant to be is more like this:
Encore
// directory where compiled assets will be stored
.setOutputPath('public/build/')
// public path used by the web server to access the output path
.setPublicPath('/public/build')
// only needed for CDN's or sub-directory deploy
.setManifestKeyPrefix('public/build/')
So the public path should still be absolute while the "manifest prefix" takes care of the set up as a subdirectory.
Information on this can be found here:
webpack-encore-readme
webpack-encore-issue-13
Just added this for correctness, as I stumbled over it and others might as well...
I resolved it at the end, after testing many things. There was 2 problem I kept repeating.
First, the path was generated in a not relative way, solve it changing webpack with this:
.setPublicPath('./')
But then the scss didn't load, what happen? Well, the prefix was the problem, because when you put the prefix in the asset function it takes the prefix and change it for the public path... so I changed the prefix for
.setManifestKeyPrefix('webpack/')
(something random really)
Consider the following loop
{% for product in collections.settings[collection_setting].products %}
{{ settings[collection_setting] }} - {{ product.title }}
{% endfor %}
Here settings[collection_setting] is equal to green but this does not work. If I have this static it works example
{% for product in collections.green.products %}
{{ settings[collection_setting] }} - {{ product.title }}
{% endfor %}
Can anyone please explain why this happens and how to solve this.
Answer
Sorry for wasting your time. This helps me to work.
Working
{% for product in collections[settings[collection_setting]].products %}
{% endfor %}
collection_setting seems to be a ruby variable. Hence to have the liquid template engine evaluate this, you'll need to have it in double braces ({{collection_setting}}).
Where you have this:
{% for product in collections.settings[collection_setting].products %}
...are you sure you don't mean this?
{% for product in collections[collection_setting].products %}
Your non-working example has a .settings where your working example does not.
I would like to include a file in a swig template without swig parsing it as a swig template. Something like raw tag for files.
Using swig-highlight I would like to get this working.
{% highlight 'html' %}
{% import 'some-template-file.html' %}
{% endhighlight %}
Problem is 'some-template-file.html' is a Jekyll template and throws errors in swig.
You can try using the raw tag. This ignores any inside swig syntax and should, presumably, ignore any other syntax as well.
// inside (e.g.) index.html
{% import 'some-template-file.html' %}`
// inside some-template-file.html
{% raw %} {{ testVar }} {% endraw %}
// results in "{{ testVar }}"
How is it possible to extend "erlydtl"?
I really like django templates, and the way the template language can be extended. For example, I like the extensions such as "sekizai".
It is possible to have custom tag modules for erlydtl. But how do I add support for more complex tags such as provided by sekizai?
In django, using sekizai I can do following (taken from sekizai documentation).
{% render_block "css" %}
And add following to add to the above block
{% addtoblock "css" %}
<link href="/media/css/stylesheet.css" media="screen" rel="stylesheet" type="text/css" />
{% endaddtoblock %}
And this will add the contents at the place where {% render_block %} is called.
You need to write your own module and define functions that are called and provide the data for your template tags.
Example:
File perc_filter.erl:
-module(perc_filter).
-export([percentage/2]).
percentage(Input, Whole) when is_integer(Input), is_integer(Whole) ->
[Result] = io_lib:format("~.2f", [Input / Whole * 100]),
Result.
In template:
{{ x|percentage:1000 }}
I have the following in my template.
{% block content %}
{% for album in albumsList %}
{% if fotosList %}
<div class="photoalbum-wrapper">
<h3>{{ album.title }}</h3>
<ul class="photoalbum">
{% for foto in fotosList %}<li>item</li>{% endfor %}
</ul>
{% if fotosList|length > 4 %}
больше <span>▼</span>
{% endif %}
</div>
{% endif %}
{% endfor %}
{% endblock %}
And it raises TemplateDoesNotExist: 500.html.
If i write simple {{ fotoList|length }} it works okay.
This is a very old question. Since then, newer versions of Django support operators in if-statement out of the box, so the following code will work just fine:
{% if fotosList|length > 4 %}
{% endif %}
Use fotosList.count instead of fotosList|length. you will get desired result.
FYI if tags with the operators ==, !=, <, >, <=, >= are supported now in the development version of Django.
{% if fotosList|length > 4 %} is not a valid tag; you can't use greater than/less than operators in the Django if tag. (You can use operators in the latest development release, but I'm assuming you're not using the latest version from Django's SVN repository.)
The reason you get the TemplateDoesNotExist error is because Django is throwing a 500 Internal Server Error (due to the invalid tag), but you haven't supplied a 500.html error template, as noted here.
