Why are uploaded images via Django admin not showing up in the production server?
I have the following model field logo = models.ImageField(upload_to=municipality_logo_file_name) and function that uploads the image to the desired location. def municipality_logo_file_name(instance, filename): name, extension = os.path.splitext(filename) return os.path.join('municipality', 'logo', str(uuid.uuid4()) + extension.lower()) In the development mode, a file uploads correctly to for example /media/municipality/logo/1e3cc24a-841b-4577-aa59-b53e5b10420b.png and then displays correctly in the template using <img src="{{ municipality.logo.url }}" alt="Logo obce" style="max-height: 8rem; width: auto"> In the production, file uploads well, but does not display in the template and the url cannot be followed to display image, the response is Not Found The requested resource was not found on this server. Any hint as to why this might be happening would be much appreciated. -
DJANGO translate complex template variable
I would like to translate a more 'complex' template variable, however I am running into unexpected error. The simple texts on my template are translated properly. I have a template variable that looks like this: {{ days|index:class.gym_class.day }} days is a list of week days, index is a custom tag that looks looks like this: @register.filter def index(List, i): return List[int(i)] The variable evaluates to "Monday" I have this in my .po file, and the .po file is compiled msgid "Monday" msgstr "Hétfő" Now if I want to translate the variable like this: <td>{% trans days|index:class.gym_class.day %}</td> I get an error: AttributeError at /hu/login 'list' object has no attribute 'replace' To me it seems, that the translation tries to happen before the template tag evaluation? I also tried <td>{% blocktrans %}{{ days|index:class.gym_class.day }}{% endblocktrans %}</td> Which interestingly returned nothing. Neither "Monday" neither "Hétfő" is printed. How can this problem be solved? -
DJANGO translate template variable
I am having problems translating template variables according to this thread: django translate variable content in template Simple text on the template get translated perfectly, however evaluated template variables dont. I have a template that looks like this: <td>{{ days|index:class.booking.day }}</td> The variable there evaluates to "Monday", with capital M and no spaces. In my .po file, I have msgid "Monday" msgstr "Hétfő" After compiling the .po file I thought I should be able to translate this by <td>{% trans days|index:class.booking.day %}</td> But only "Monday" is shown, not its translation. I also tried blocktrans to no avail <td>{% blocktrans %}{{ days|index:class.booking.day }}{% endblocktrans %}</td> What am I doing wrong? -

Angular CRUD backend frontend
In Django I build a backend, with the Model Person, which contains of two foreign keys: 'gender' and 'work'. I have build the REST API for the app and it is working as intended.

I will do edits with code, if you tell me which files are needed. Because I have no idea where my error is. -

Save position in sortable list
I'm trying to make an sortable list for a website with Django, I need to keep the order of the cards when they are changed position, saving this in a database table. The POST method below, returns me the old position of the card, the new position and the ID of a card. $(function() { var start_pos; var end_pos; var id; $('#sortable').sortable({ start: function(event, ui) { start_pos = ui.item.index(); ui.item.data('start_pos', start_pos); }, stop: function(event, ui) { end_pos = ui.item.index(); id = ui.item.attr("id"); $.ajax({ url: "/project/", data:{ start_pos, end_pos, id, csrfmiddlewaretoken:$('input[name=csrfmiddlewaretoken').val() }, method: 'POST', }) }, update: function(event, ui) { $('#sortable li').removeClass('highlights'); } }); }); In the database, each card have a ID and and "order_number" fields, when the card changes, I want to keep the ID the same and the "order_number" change, replacing the older "order_number". I don't have any idea how make an SQL statement to save this order or something in the jQuery code. Thanks in advance! -
Django Datatables View filter/search

In which Model should I include approved status of a labour getting a particular job?
So I have created 2 models namely JobModel and LabourModel and I have used Many-to-Many relation between them because 1 labour can apply for multiple jobs and there can be multiple labours applying for 1 job.

How do you containerize a Django app for the purpose of running mulptiple instances?
The idea is to create a Django app what would serve as the backend for an Android application and would serve an web admin interface for managing the mobile application's data. Different sites of the company sometimes need different backends for the same android app (data has to be manageable completely separately). Application will be hosted on Windows server/s. How can I containerize the app so I can run multiple instances of it (listening on different ports of the same IP) and I can move it to different servers if needed and set up a new instance of it there? The Django development part I'm familiar with but I have never used Docker(nor other) containers before. What I need: Either a tutorial or documentation that deals with this specific topic OR Ordered points with some articles or tips how to get this done. Thank you. -

When I try to apply the migration, I get the following error message: psycopg2.errors.UndefinedObject: constraint "actstream_follow_user_id_content_type_id_object_id" of relation "actstream_follow" does not exist Inspecting my database as it is without the migration, tho, I see the following: What am I missing?
