Django - How to create multiple users for a single app
myproject ---myapp I have created a django project which has an app in it that does viewing , adding data to database etc. Now I want to create multiple users who can use this app with their own data. What is the best way about it. Lets say there are 3 users user1, user2, user3 Currently I am planning to do this. I copy the myapp code and create 3 apps corresponding to each user. So the project directory looks something like this myproject ---myapp ---myappuser1 ---myappuser2 ---myappuser3 So I now have 3 apps with similar functionality and each of the user has their own data. Now, the hurdle is how do I restrict access so that each user can see his own app. For instance, user1 should be able to only see myappuser1 contents and user2 should only see myappuser2 contents. How can I do this ? I tried creating groups in django admin but that only gives me permissions to edit the items under the myapp. It doesn't restrict user to not allow other user pages. Option 2: Create seperate django project for each user. This solves the user restriction but to deploy in heroku I should register … -
list object has no attribute "values"
In Django, this is my code and it is working fine. from myapp.models import Users user = Users.filter(organization ="abc").order_by("-created_at")[offset:offset+limit] user.values("id") But when I try to break the code into smaller parts, it throws an error on the third line saying: attribute error: list object has no attribute "values" from myapp.models import Users user = Users.filter(organization ="abc").order_by("-created_at") user = user[offset:offset+limit] user.values("id") I was just wondering why it is happening? -
Django Use a String as ForeignKey
I have a quick conceptual question that I would like to solve. I have a model that upon saving an instance of that model, saves the id as an md5 hash (ex. '11db608cba69c0a09b4d5abde2553b56'). Saving this model works fine, but now I am trying to save additional information by creating a new model that references this model as a foreign key. Upon saving that additional model I get the following error: invalid literal for int() with base 10: '11db608cba69c0a09b4d5abde2553b56'. Doing some searching I found a nice stack post that answers what I believe to be happening. It said that by default, a ForeignKey field is of type integer. Therefore whatever value is referenced by it must be an integer. I would like to be able to define a model that uses a str-based foreign key (or anything that will allow it to except the md5 hash). Is that solution possible? The only other thing I could think of doing is generating an integer based on the md5 and using that as a reference, but it seems like an unnecessary step. I also found some other posts that referenced GenericForeignKey. I'm having a bit of trouble wrapping my head around it, but … -
How to implement Giphy into blog post comments in Django?
I would like to offer the option to insert Gifs via the Giphy API into blog post comments for my readers. I have a plain vanilla comment form + model like so: forms.py # Blog Post Comment Form class CommentForm(forms.ModelForm): class Meta: model = Comment fields = ('name', 'text',) models.py # Comment Model class Comment(models.Model): post = models.ForeignKey('blog.Post', on_delete=models.CASCADE, related_name='comments') name = models.CharField(max_length=200) text = models.TextField() created_date = models.DateTimeField(default=timezone.now) approved_comment = models.BooleanField(default=True) def approve(self): self.approved_comment = True self.save() def __str__(self): return self.text Now I am stuck when it comes to the basic concept of how I could implement the Giphy API into the form/model instances. My idea is to make an async Ajax call to the Giphy API endpoint once the user entered a search term. Then the API would return a bunch of gifs and the user selects one. I guess that the Django Textfield isn't capable for this purpose. Now how to insert the selected gif into the comment and save it to the database? -

AWS Elastic Beanstalk failed to install Python package using requirements.txt - Firebase-Admin
I have searched similar questions, but no answers solve my problem. I am trying to install firebase-admin using pip. Everything works well locally, but when I push to aws elastic beanstalk it gives me the error below When I remove firebase-admin and its dependencies everything works fine. I think it may specifically have an error with grpcio being installed but not completely sure, and firebase needs it installed to work. Some answers say that firebase-admin is dynamic and aws else does not support that. I am wondering if there is a solution to this problem so I can install firebase.

django ckeditor set with different s3 bucket
I'm implementing ckeditor with my django app, the problem I have is: Django-ckeditor doesn't work with s3 buckets that are not public. I need the s3 bucket to be private to prevent abuse. My thoughts are setting the django-ckeditor upload to a different s3 bucket and setting it as public. I want to know if that is possible as that isn't documented by django-ckeditor. If I set the s3 bucket to be public, will people be able to upload files outside my sites (does setting it public ignores CORS settings)? If the above thought is incorrect, is there an alternative way of doing it without affecting my main media storage?, or an alternative package for rich text editor. Thanks in advance. -
Use entire set of views in two different URL confs in Django
I'm building a web app that displays TV Shows and Episodes. All my urls are geared towards TV Shows being the top level concept: mysite.com/tv-show-name/episode-name mysite.com/tv-show-name/episode-name/cast mysite.com/tv-show-name/episode-name/reviews I've gotten interest from Networks for consolidated pages with their shows as subdirectories mysite.com/network-name/tv-show-name/episode-name mysite.com/network-name/tv-show-name/episode-name/cast mysite.com/network-name/tv-show-name/episode-name/reviews I'll need to support both, and obviously I dont want to repeat all my non-network URL confs. Is there a simple way to do this? -

Controlling duplicate entries with Django
Django offers the possibility to use the * exists * function which returns a boolean a = Predicates.objects.filter(predicate = predicate).exists() print (a) True I need to occupy the ID (PK) of that record if it exists so I use get try: return Predicates.objects.get(predicate = predicate) except Predicates.DoesNotExist as errorNoExiste: return None That code in a function exists = self.search_predicate (predicate) now on reaching the conditional if exists is None: if or if you enter and proceed to save, which produces a Duplicate Entry in the model the attribute is obviously unique. Any ideas as I said I need the ID of the record if there is to make another record and why this ID is your FK (instance). -

Django channels zero downtime code update?
I have a django channels based app in production environment. I am using supervisord to manage processes. Also I am using uvicorn via gunicorn to handle asgi requests as mentioned here. Whenever I have something new to deploy, I have to restart gunicorn process and it will destroy all old websocket connections and connect them again. Is there a way to persist those websocket connections. Basically, it puts a sudden load on server as every device tries to reconnect after few seconds of disconnection. There is concept of sending HUP signal Link to gunicorn so that only workers processes restart, but even restarting worker processes disconnects websocket connection. Is there a way to do it without losing old websocket connections? Or if not is there a way to avoid sudden load on server on server restart? Can I do it using some proxy server? -
Nginx will not serve django media files, but will serve static files
