How to model this field/relation using Django
I'm creating an API using the django rest framework want to store an array of pictures inside my user model. For each picture I should have an URL and boolean flag indicating whether it is the display picture or not. There should be atleast 2 and maximum 6 pictures. One and only one of those pictures should have the display_picture_flag set as true. What would be a good way to model this. My approach (Might not be best) - I'm thinking of creating another model class with user id from user class as the foreign key. It will have an URL field and a boolean field aswell. My doubts with this are, How will I validate number of objects as lying in [2,6]. Validating that only one flag is true. Creating [2,6] objects at the same time (single Create API call). Using JSON field. probably store as dictionary with URL mapped to flag. Again, confused with validations. Please suggest better approaches, or expand upon my approaches. Thanks! -
How to manage and save nested arrays to django models
I'm receiving the data from the frontend app in the form of Arrays, or say List of objects. I want to create and save the data using Django models and views. I'm a little confused about how can make a structure of tables to save this type of data That's how would be I receiving data: [ { question: 'Screen Works Properly', parentId: 1, child: [] }, { question: 'Theres issue of Hardware', parentId: 2, child: [ { id: 15, sub_question: 'Broken Speakers' }, { id: 18, sub_question: 'Battery Damaged' } ] } ] There could an unlimited number of objects in the list and every object has a child array which can have an unlimited number of objects as well. I can see there I can make a model Data and then can link the objects with ForeignKey, But how will I manage the child Array/list in the object. Can anybody give me an idea of how can I create models to save this type of data? -
How to submit form using jquery submit

how can I receive notification by another user using channels in django?
actually, this is the first time I use channels but it's an easy concept to understand. I followed a tutorial that took me to the way in which I can send the notification the real-time but there's a part that I can't see at any tutorial where they are oblivious to it. all tutorials show how can send a notification or messages via chat when I do that for a single user after I open the new page, the page works fine. for example, if I logged in by username "test" and opened a new browser logged in by username "test" will be working fine the problem is that: when I try to open for example an "incognito page" by google chrome to use a different user such as "new test" username that I want him to receive the notification we can consider him a target user from the sender on the main page "test". now the data is changing in the data but I can't see that change in front of my eyes unless I reload the web page. when I tested that out I see javascript doesn't receive any of the data in the "new test" user and … -

Specific Viewing Privilege's in HTML and Python
I'm making a college events website for a project and one of the requirements is to be able to make events that are private for your student organization or your university. So all events should be tagged as either Public, Private(can only view if you attend the same university as the event creator), or RSO(can only view if you are in the same student organization as the event creator). I have managed to make a page where you can view all the events but I can't figure out how to make it so you can only view these events under the provided circumstances. Right now all the events no matter what the tag is show up for everyone looking at the events list page. Any ideas on how to do this? -
