Upload multiple photos in Django REST admin panel
I can't find a solution to upload multiple photos to one ImageField in admin panel. I had StackedInline but it's not what I need because there each photo must be upload to new ImageField. I've gone through many questions which might have been close to mine but haven't got a solution yet. Admin panel is pretty much main part of my app. Is is possible to achieve this result in admin panel? This is how I want to see it models.py from django.db import models class User(models.Model): first_name = models.CharField(verbose_name='Имя', max_length=40) last_name = models.CharField(verbose_name='Фамилия', max_length=40) rfid_mark = models.CharField(verbose_name='RFID', max_length=10, editable=True, unique=True) registration_date = models.DateTimeField(verbose_name='Дата регистрации', auto_now=True, editable=False) def __str__(self): return self.first_name + ' ' + self.last_name class UserImage(models.Model): user = models.ForeignKey(User, verbose_name='Пользователь', on_delete=models.CASCADE) photo = models.ImageField(verbose_name='Фото') def __str__(self): return '' -
How to scale mysql table to keep historic data without increasing table size
I have a questionnaire in my app, using which I am creating data corresponding to user who have submitted it and at what time(I have to apply further processing on the last object/questionnaire per user). This data is saved inside my server's MySQL db. As this questionnaire is open for all my users and as it will be submitted multiple times, I do not want new entries to be created every time for same user because this will increase the size the table(users count could be anything around 10M), But I also want to keep the old data as a history for later processing. Now I have this options in mind: Create two tables. One main table to keep new object and one history table to keep history objects. Whenever a questionnaire is submitted it will create a new entry in history table, but update the existing entry in main table. So, is there any better approach to this and how other companies tackle such situations? -
How can I split orders by attributes in my API

How to create the login and signup urls/views with django rest framework + firebase auth
I was trying to configure django rest framework with firebase auth. I had a look into a few tutorials and firebase doc.

Tockenizing any model instance in django (DRF)
So i am working with Django and django-rest-knox for token based authentication. It works fine but what i want now is to tokenize any other model instance instead of a user istance. Normal way; from knox.models import AuthToken AuthToken.objects.create(user=myuser) What i tried; AuthToken.objects.create(some_other_model_instace) Which gives an error; AuthToken.user" must be a "User" instance Is there any way to do so? -
Django Makemigrations fails on new autoscaling instances (shows no new changes)
We have a django backend hosted on Autoscaling ec2 instances, and during the deployments it has found that makemigrations and migrate fails (with new models added) when the new ec2 replaces in auto scaling group, as the migrations were done from the old instances, it shows no new migrations on the latest ec2. What could be the efficient solution for this - To have a separate server only for database migrations To push the migrations file directly on git/bitbucket with code so that during deployments new changes are reflected. Is there any other good solutions for this in general? -
How to view contents of one model to another model?

I want to seperate the items in Inventory class in tabs, for example i have a tab inside the Test class and have all the items in it. How can i do this? -
Changing primary key in Django caused constraint does not exist error
I have Django project with DigestIssue model among others and there were Django auto created primary key field id and my field number. I wanted to get rid of duplication and set number as PK because number is unique and with same values as id. But I have foreign keys referencing this model. I doubt that they will migrate automatically after such operation. I tried, hoping for such automigration and got constraint "idx_16528_sqlite_autoindex_gatherer_digestissue_1" of relation "gatherer_digestissue" does not exist error ("sqlite" in constraint name is historical thing, I switched to PostgreSQL a time go). I tried more complicated way, following https://blog.hexack.fr/en/change-the-primary-key-of-a-django-model.html but got same error on PK switching step. So the question is - how to replace in Django old primary key with new one with same values and referenced by other models? -
CSRF follies when trying to log in to Django with Python requests/sessions
I'm trying to log in to Django using Python requests. There are old questions about this, but none of them are answered due to inadequate details. There are two CSRF tokens involved in this. One is the cookie, and the other is part of the login form. I've verified that Chrome returns the cookie token in the cookies and the form token in the body, and my url encoded body matches the format of one my browser passes back. And yet I still get "Forbidden (CSRF token missing or incorrect.)" as my response. Can any one suggest what I might be doing wrong? My Python looks like this: def login(url, username, password): session = requests.Session() response = session.get(f"{url}/accounts/login/") print(f"First headers: {response.headers}") header_csrftoken = session.cookies['csrftoken'] print(f"Header csrftoken: {header_csrftoken}") soup = BeautifulSoup(response.text, "html.parser") form = soup.find("form", {"id":"login-form"}) found = form.find("input", {"name":"csrfmiddlewaretoken"}) form_csrftoken = found['value'] print(f"csrftoken2: {form_csrftoken}") data = {'csrfmiddlewaretoken': form_csrftoken, 'username': username, 'password': password, 'next': '/'} response2 = session.post(f"{url}/accounts/login/", data=data, headers={'content-type': 'x-www-form-urlencoded'}) print(f"outgoing: {response2.request.body}") print(f"Headers: {response2.request.headers}") First headers: {'Date': 'Mon, 20 Sep 2021 03:37:17 GMT', 'Server': 'WSGIServer/0.2 CPython/3.8.12', 'Content-Type': 'text/html; charset=utf-8', 'Expires': 'Mon, 20 Sep 2021 03:37:17 GMT', 'Cache-Control': 'max-age=0, no-cache, no-store, must-revalidate, private', 'Vary': 'Cookie, Origin', 'X-Frame-Options': 'DENY', 'Content-Length': '20609', 'X-Content-Type-Options': … -

Why is my upload directory relative to the project directory but Django is trying to get it from an app related path?
I am building a Dev-blog to store and refer to project I've coded for my portfolio, and I've been trying to add a media upload capability to my post text boxes. I started off by using a standard RichTextField, which had a built-in function to add Images through URL(No uploading). It worked fine, but I wanted the ability to upload photos from my machine. The blog is fully operational (on a local server for development), so all irrelevant code was disregarded.

Django manytomany field automatically populates with all objects of related Model
I just added two manytomany fields to a django model; however, when I create a new instance of the model with the manytomany fields, the fields automatically contain all instances of the models they are related to.

Django MySQL Row size too large. The maximum row size for the used table type, not counting BLOBs, is 65535
I am currently migrating my tables to a new MySQL database from SQLite. There were no issues when I migrate to SQLite but when I try to migrate on to MySQL, I get the error above. I think it was due to my textfields taking up much of the space so I added a max_length=500 attribute to all of them but the error persists. This is the error: Is there a way to resize the textfield, or resize the maximum row size? Thanks in advance. -
Django URL Not Matching with Intended View
I'm having trouble figuring out why tag pages for my blog are trying to pass to a different view than the one I intend. My /tag/ url's should go to TagsListView, but instead are going to PostDetail. My url structure: app_name = 'blog' urlpatterns = [ path('', views.home, name='home'), path('search/', SearchResultsView.as_view(), name='search_results'), path('tag/<slug:slug>', views.TagsListView.as_view(), name='blog_tag'), path('<slug:slug>/', views.CategoriesDetail.as_view(), name='categories_detail'), path('<slug:categories_detail>/<slug:slug>/', views.PostDetail.as_view(), name='post_detail'), path('<slug:categories_detail>/<slug:slug>/comment', views.CommentCreateView.as_view(), name='post_comment_create'), ] View: class TagsListView(ListView): model = Tag template_name = 'blog/tags.html' Template (implementation has to be dynamic): <a href="/{{ tag.slug }}"><h4><span class="badge badge-primary">{{ tag }}</span></h4></a> For some reason the url, domain.com/tag/tagname will try to match and run through the PostDetail view and 404, instead of the TagListView. Everything seems like it should match, so I'm not sure why it's skipping that over. Also, I believe I should have the model for the TagListView set to Post (blog posts), and create a custom queryset that filters based on the slug for the requested tag. Correct? Or is it the other way around? I haven't gotten to that point to test yet and wondering the best approach there. Thanks. -
Axios is sending OPTIONS instead of POST to Django
I'm using Django Rest Framework with a front-end in Vue. I'm using axios to make POST requests to Django, but the Django server is receiving OPTIONS requests, as you can see in the server log. "OPTIONS /save/ HTTP/1.1" 200 0 Broken pipe from ('127.0.0.1', 59396) The problem doesn't appear to be in the server, since CORS is configured correctly and I can send a POST request with Postman. Here's the javascript code async save() { let data = { "name": this.name, "title": this.title, } let config = { header : { "Content-Type": "application/json", } } response = await axios.post( 'http://127.0.0.1:8000/save/', data, config ) } -
Django: ModuleNotFoundError: No module named (django unable to import modules?)
When attempting to debug a file named "formulas.py", I got the following error: ModuleNotFoundError: No module named 'ingredients'. This was strange, as yesterday I debugged the file and it worked perfectly. To my knowledge, I didn't change anything that should have impeded django's ability to load my module. My file structure is the following: Blocky_alchemists blocky_alchemists ingredients media playground database manage.py In playground there are (among others) my formulas.py and views.py, and in ingredients I have my models.py which contains the model called "Ingredient".

Basically, when something happens in relation to a certain app on the server end of things, I want to send a notification to that client app to react accordingly. Almost like a webhook but for mobile. It's important to know that in practice, I won't be the owner and developer of both the client-side app and the server-side software, just the server-side. If anyone knows how to do it natively on either Android or iOS that would be appreciated too.
