Django - Hierarchical relation between 3 models. Post references a Goal and Goal references a Category
So I'm trying to think of how to organize this weird relation I have. So posts are always associated with a goal, they can't not be associated with a goal. This of it like this so if your goal is to "lose weight" then your post can be an update like "ate a salad today!" So all posts must reference a goal in this way, then each goal type can have a category type. For example, 'weight loss' goal is of type 'health & fitness' category. I need to be able to query all posts related to a category quickly as well as all posts related to a goal. I have 2 ways of doing this Method 1: class GoalAndPostCategory(AbstractBaseModel): category = models.ForeignKey(Category, on_delete=models.CASCADE) goal_id = models.ForeignKey(Goal, on_delete=models.CASCADE) post_id = models.OneToOneField(Post, on_delete=models.CASCADE) Create a table where each row is just the category, goal and post, but this doesn't ensure that let's say goal 1 with post id 1 is the same category as goal 1 with post id 2. Since they're separate rows there's the possibility of inconsistency (Not sure how big of a deal this is). Method 2: class Goal(AbstractBaseModel): creator_id = models.ForeignKey( User, on_delete=models.SET_NULL, null=True, related_name="goal_creator_id") end_date = … -

Recreate Django table without affecting the frontend experience
Every month, I need to delete all data in a table and refill that table with new data. Since the frontend fetches and display data from the said table through a serializer, users might experience a crash when the old data is deleted but the new data hasn't written in. So, to not disrupt users' experience, I'm thinking about the following procedure: Clone the existing table Write new data to the new table Rename the new table to match the Django model name Delete the old table I was wondering if there's any Django built-in method to achieve this? The cloned table must match everything defined in the model so that upon deleting the old table, the frontend would continue working smoothly. -
Django - UpdateView changes are not saved, success_url is not used
I think I have a pretty basic UpdateView but the object is not saved when I submit the form. The success_url is never called. When I click the Update button, the form refreshes and I stay on the same page. I am able to update the object via admin, so I believe the model is working fine.

How to handle multiple ClientId s for single social auth provider
I am trying to implement social auth for my backend that will serve mobile apps on different platforms (IOS, Android). I am using django-allauth.socialaccounts to accomplish the task. The problem is that for ex Google requires to have an OAuth client ID per each platform. That said I cannot create multiple social apps with the same provider because I am starting to get MultipleInstancesReturned error. I am thinking about attaching different Site instances to the applications, but not sure if sites framework is good for distinguishing mobile platforms. The resulting question is pretty simple - how to implement social login having more than 1 client id for provider? -

How can I allow users to create their own posts in Django?
I am trying to build a discussion forum with Django. I first did a test post with Django admin, but now wanted to implement a form so that any user can post. The idea is that the home page of the forum has a list of all existing posts, and clicking on the "Create a Post" button would take them to the post form, and after submitting they can see their post on the list. I have the code for the form ready and thought I had hooked it up correctly to the URL, but I am getting a blank page when I click on "Create a Post". I am new to Django, and need some help solving this.

Save Calculated Value from View to Model in Django
