Django - How set headers for external resources?
At my Django application, I want to display an image from an external web server. This web server only returns the image if an Authorization token (JWT) is set in the request header. At my Django template, I do: <img src="{{ blabla.cover_url }}"> Where cover_url is a model function, which looks like this at the moment: def cover_url(self, *args, **kwargs): jwt_payload = jwt_payload_handler(get_request().user) access_token = str("Bearer " + jwt_encode_handler(jwt_payload)) cover_url = "https://cdn.mydomain.com/Images/123456789.jpg" My question now is how I return the cover_url with the Authorization header set? -
Login Failed Error Message Django Based Views
I have a project made in django based view. I need to show an error message when the user enters the wrong password, but in every forum I've seen so far there is a suggestion to use a 'Form'.

Password reset using graphene-django?
In our on going project we are migrating all our views from django to react using graphene. Originally, we used the built in django authentication system for user registration, login and password reset. To migrate the login view, we used authenticate and login from django.contrib.auth which worked great. But now we are stuck on the password reset view. We cannot find a way to send the password reset email. Are there any built in functions like the ones mentioned before that we could use? I checked the following project https://github.com/PedroBern/django-graphql-auth, but it seems abandoned, so I would like to avoid it. -
Losing data in db.sqlite3 when deploying django project to heroku
Whenever I make updates to my website I lose all data that has been added to my models. For example my models include users and service_calls and when I push a deploy it overwrites my db.sqlite3 file and I'm back to just my superuser being the only user and 0 service calls in my database. How can I push an update without having my db.sqlite3 file overwritten? Is that possible or do I need to have my local db.sqlite3 file updated before deploying and if so how would I go about that. Thanks in advance -
Django - How to process authorization headers?
At my Django application, I display pictures which are stored on an external web server. To make the picture accessible, the client needs to call the resource with an attached authorization Barer token in the request header, like this: Authorization: Bearer eyJ0eXAiO... To get the actual URL to the picture, I have a function in my models.py which I can simply call at my template.html: def cover_url(self): cover_url = self.libera_backend.endpoint + '/' + self.libera_backend.assets_bucket + '/' + self.cover_path return cover_url As I have to generate a JWT token to make the resource accessible, I have to do something like this: jwt_payload = jwt_payload_handler(user) access_token = str("Bearer " + jwt_encode_handler(jwt_payload)) Where I'm not sure how to implement this. Does it have to be part of a template tag, or is there any way to find out what user calls def cover_url? If so, how can I add the Authorization header here? -
Dynamic SECRET_KEY in Django disadvantages
I just started learning Django and I'm wondering what the drawbacks of using a randomly generated SECRET-KEY would be. So far I've started with using this code... from pathlib import Path import random, string Build paths inside the project like this: BASE_DIR / 'subdir'. BASE_DIR = Path(file).resolve().parent.parent Quick-start development settings - unsuitable for production See https://docs.djangoproject.com/en/4.0/howto/deployment/checklist/ Randomized security key size = 100 SECRET_KEY = ''.join(random.choices(string.ascii_uppercase + string.ascii_lowercase string.punctuation + string.hexdigits + string.digits, k = size)) For now, this seems to work well for a simple blog that I made but I'm wondering what drawbacks this might have in other uses and if there are better ways of making the key secure. Thanks in advance! -

AJAX only picks first element id in a DJANGO loop
AJAX only picks first element id in a DJANGO loop. Wherever I click the "edit" button it brings the first post content. I've just similar metholodogy in other functions (for example a like button) but in this one I don't really see what it only picks the top element of the loop in every template. Please help.

SUBMIT button for Django Modal Forms not working, no url to direct to
So, I am trying to add data into a db with the usage of a modal, for this, I am using django-bootstrap-modal-forms. I followed the steps on the manual, step by step and I finally made it work. Well, everything except the buttons on the modal. First, to dismiss data, it had to be data-ds-dismiss instead of the data-dismiss appearing on the code, but that's fine. The only thing that I cannot get to work is the CREATE button, to add data to the database. Here is my code (which is pretty much what appears on the site previously mentioned): #contform.html <form method="post" action=""> {% csrf_token %} <div class="modal-header"> <h5 class="modal-title">Create new contract</h5> <button type="button" class="close" data-bs-dismiss="modal" aria-label="Close"> <span aria-hidden="true">&times;</span> </button> </div> <div class="modal-body"> {% for field in form %} <div class="form-group{% if field.errors %} invalid{% endif %}"> <label for="{{ field.id_for_label }}">{{ field.label }}</label> {{ field }} {% for error in field.errors %} <p class="help-block">{{ error }}</p> {% endfor %} </div> {% endfor %} </div> <div class="modal-footer"> <button type="button" class="btn btn-default" data-bs-dismiss="modal">Close</button> <button type="submit" class="btn btn-primary">Create</button> </div> </form> What appears on my console is django.core.exceptions.ImproperlyConfigured: No url to direct to and yes, it makes sense bc Im not adding any … -

Avoid duplication in Django for loop with a many to many relationship
My goal is to list the tag_titles for each note created. I am having issues because the tag_title and note are linked through a Many to Many relationship. How I would normally do this is: {% for note_tag in note_tags %} {% if note_tag.note == note %} {{note_tag.tag_title}} {% endif %} {% endfor %} However, because tag_title has a many to many relationship with NoteModel, note_tag.note gives out notes.NoteModel.None My models.py are as follows: class NoteModel(models.Model): note = models.CharField( max_length = 5000, ) note_title = models.CharField( max_length = 500, blank = False, null = True, ) project = models.ForeignKey( IndividualProject, on_delete=models.CASCADE, related_name = "note_projects", blank = False, null = True, ) tag = models.ManyToManyField( 'NoteTagModel', related_name="tags", blank= False, through = "TaggedModel" ) def __str__(self): return f"{self.note_title}" class NoteTagModel(models.Model): note = models.ManyToManyField( 'NoteModel', related_name="tag_notes", blank= False, through = "TaggedModel" ) tag_title = models.CharField( max_length = 200, default = "General", ) def __str__(self): return f"{self.tag_title}" class TaggedModel(models.Model): note = models.ForeignKey(NoteModel, on_delete = models.CASCADE) tag = models.ForeignKey(NoteTagModel, on_delete = models.CASCADE) def __str__(self): return f"{self.note} | {self.tag}" class TagCommentaryModel(models.Model): tag_title = models.ForeignKey( NoteTagModel, on_delete=models.CASCADE, related_name="tag", blank = False, null = True, ) tag_commentary = models.CharField( max_length = 5000 ) def __str__(self): return f"Tag: {self.tag_title} … -
Querying a Django model and comparing its fields for similarities or near duplicates
I have a model that records changes to other models in my database. I would like to query for changes that only add a newline character -- \n. My changes model looks like this: class Change(models.Model): object_type = models.ForeignKey( ContentType, related_name="object_change_set", on_delete=models.CASCADE, ) object_id = models.CharField(max_length=255, db_index=True) object = GenericForeignKey("object_type", "object_id") old_fields = models.JSONField(encoder=JSONEncoder, null=True, blank=True) new_fields = models.JSONField(encoder=JSONEncoder, null=True, blank=True) Essentially, I want to find instances of Change where the difference between a value for a key in old_fields and new_fields is \n. Here's what new_fields look like: { "body": "Had a great time on Wednesday.", "created": "2022-06-15T19:49:06.784Z", } And similarly, old_fields: { "body": "Had a great time on Wednesday.\n", "created": "2022-06-15T19:49:06.784Z", } Note that new_fields and old_fields are both JSONFields. Ultimately, I want to remove the Change instances that only add \n to the body. I realize that I could do this by iterating over the queryset and looking for these discrepancies, but I'm wondering if there's a more elegant solution. -

Is there a way to set a Django model IntegerField default to the ID of the newly created record?
Lets say we have the following model: class MyModel(models.Model): some_int = models.IntegerField() I would like the value of MyModel.some_int to default to the value of MyModel.id. For example, immediately after creating a new record in an empty version of MyModel, I could call MyModel.objects.get(id=1) and receive an object with id=1 and some_int=1. Is there a way to do this? Edit: My current workaround is to set the default to 0, then go back and populate the value with the id of the created record, but that is messy. For context: On an existing model similar to MyModel, I am being asked to add a new column that will render using the MyModel index obsolete as the reference point for the records in that model. Instead, I am adding a new, secondary column, that should store the values of the old IDs for previous records, and new values for future records. To do that though, I need to populate the column first.
