Static files from AWS not served when they contain a Django {{variable}}
I have a Django App, deployed on Heroku with AWS S3. All static and dynamic files are being served, except when the static file name contains a Django variable. <div class="sibling" id="left"> <a href="{% url 'showtree' sibling_left_id %}"> <img src="{%static '/img/siblingsLeftFrame'%}{{no_siblings_left}}.png"> </a> </div> The generated URL should be (for example): ...amazonaws.com/img/siblingsLeftFrame02.png But looks like this: ...amazonaws.com/img/siblingsLeftFrame?X-Amz-Algortihm=AWS-4-etc.(credentials, date etc.).png Locally it works, but on Heroku/AWS I get a 403 Response. Is this a CORS problem? Here are the settings: INSTALLED_APPS = [ ... "corsheaders", ] MIDDLEWARE = [ 'corsheaders.middleware.CorsMiddleware', 'django.middleware.security.SecurityMiddleware', ... ] CORS_ALLOW_ALL_ORIGINS = True -
Module not found un uwsgi.ini when setting up Django and Docker
I'm getting a weird error when trying to run a Django server in Docker with uWSGI, for some reason the configuration file can't pick up the path to Django's wSGI file. I've run the app with just the regular "runserver" and things work fine, so I'ts not t an issue with the Django app, rather with the configuration file and how it accesses the directories in the Docker environment. I've also tried running: docker system prune -a --volumes To make sure that there isn't a problem with a redundant structure of volumes that got into the way. The error message: web_container | Traceback (most recent call last): web_container | File "/code/./docker/projectile/projectile/wsgi.py", line 16, in <module> web_container | application = get_wsgi_application() web_container | File "/usr/local/lib/python3.9/site-packages/django/core/wsgi.py", line 12, in get_wsgi_application web_container | django.setup(set_prefix=False) web_container | File "/usr/local/lib/python3.9/site-packages/django/__init__.py", line 19, in setup web_container | configure_logging(settings.LOGGING_CONFIG, settings.LOGGING) web_container | File "/usr/local/lib/python3.9/site-packages/django/conf/__init__.py", line 82, in __getattr__ web_container | self._setup(name) web_container | File "/usr/local/lib/python3.9/site-packages/django/conf/__init__.py", line 69, in _setup web_container | self._wrapped = Settings(settings_module) web_container | File "/usr/local/lib/python3.9/site-packages/django/conf/__init__.py", line 170, in __init__ web_container | mod = importlib.import_module(self.SETTINGS_MODULE) web_container | File "/usr/local/lib/python3.9/importlib/__init__.py", line 127, in import_module web_container | return _bootstrap._gcd_import(name[level:], package, level) web_container | ModuleNotFoundError: No module named … -
Django and DRF - checks for constraint before ID
In my Django project I use DRF. One of my models, Type, has a constraint; the name field should be unique. Another model, Project, relation to Type; a project always has a type. The serializer for Project has another relationship that I'd like to write in. For this purpose, ProjectSerializer implements WritableNestedModelSerializer from this package. Here's the problem: when making a new Project, one shouldn't also (be able to) create a new Type at the same time. However, it seems that Django does check if this would be allowed. This leads to an error, because when sending a Project object in a POST, it checks if the Type object given is allowed to be created before checking if it contains and ID field, indicating that it's using an already existing type. Because of this, I get an error that says the name field for the Type already exists, and I can't create the new project. How do I indicate that this isn't what I want? I could just remove the constraint on the name field in Type, but I do kind of want it there. Here is relevant code: class ProjectType(models.Model): id = models.AutoField(primary_key=True) name = models.CharField(max_length=50, unique=True) is_active = … -

List from django view past to template is not showing any elements

How to change moderation in Django comments-xtd library

How to retrieve object with lookup field in Django Rest through React?
I am using the Django Rest framework as an API and React for front-end. I have everything configured to display React through Django. And everything works in development. However when using the production build I run in to an issue when trying to retrieve a single object from the database using 'slug' as the lookup field. For example I can make a call using the id field axiosInstance .get('/articles/1') which targets this view class ArticleViewSet(viewsets.ModelViewSet): ... and returns the desired article. However when I change the lookup field to 'slug' # views.py class ArticleViewSet(viewsets.ModelViewSet): lookup_field = 'slug' ... # serializers.py class ArticleSerializer(serializers.Serializer): class Meta: ... lookup_field = 'slug' and the axios call to console.log(slug) # Logs "article-1" as it should axiosInstance .get(`/articles/${slug}`) # This results in /articles/article-1 Then the index.html file is returned to me. The ArticleViewSet's retrieve method never even gets called. What's more strange is that I can still view the article using a slug by going directly to the api with, for example "localhost:8000/articles/article-1" in my browser. This returns the desired article. How can I call the retrieve method using a slug with the production build? Any help is much appreciated, thank you. -

Why doesn't this django form accept my input if it also generates the options itself?
It is a competition manager that matches the participants of a competition randomly, I call these pairs games. The game is a django model with an attribute called "ganador" to store the winner of the game. To choose the winner I use a modelform_factory called formaGanador and exclude all the attributes of the model except the "ganador" attribute. The attribute "ganador" has an option of "choices" so that the form only allows to choose one of the participants of that game and not participants of other games. Finally, when I select a participant from the list and press the submit button on the form, I receive the following response: Select a valid choice. Player A is not one of the available choices. model for games in model.py: class Juego(models.Model): torneo = models.ForeignKey(Torneo, on_delete=models.CASCADE, null=False) ronda = models.ForeignKey(Ronda, on_delete=models.CASCADE, null=False) jugadorA = models.ForeignKey(Jugador, on_delete=models.SET_NULL, null=True, related_name='jugadorA') jugadorB = models.ForeignKey(Jugador, on_delete=models.SET_NULL, null=True, related_name='jugadorB') puntuacionA = models.IntegerField(default=0) puntuacionB = models.IntegerField(default=0) ganador = models.ForeignKey(Jugador, on_delete=models.SET_NULL, null=True, default=None, choices=[('Jugador A', 'Jugador A'), ('Jugador B', 'Jugador B')]) creating the form in the views: GanadorForm = modelform_factory(Juego, exclude=['torneo', 'ronda', 'jugadorA', 'jugadorB', 'puntuacionA', 'puntuacionB']) passing and receiving the form "formaganador" from the template : def detalleTorneo(request, id): torneo … -

How to create dynamic queries with Django Q objects from parenthesis inside a string
I don't know if the title of the question is formed well enough. But essentially I would like to be able to do something like this from front end : (name="abc" OR name="xyz") AND (status="active" OR (status="available" AND age=30)) I want to the user to send this string. I will parse it in backend and form a query. I have looked at this answer and this but couldn't figure out how to solve the parenthesis here. I am thinking about using a stack (the way we solve infix expressions) to do this, but don't want to go that long route unless I am sure there isn't another/ready solution available. If someone can do this with that method, would be great too. -
