how to save search input query from url
I'm trying to implement a way to have my url search value carried over from one view to another. For example. if I have the url http://127.0.0.1:8000/post/search_result/posts?search=harry It would use my SearchPostView view to display all filtered posts with the authors name being harry. However on that same page I want users to be able to click a button that would take them to a page where it would show all users on the site with the name harry. My problem stems from when I try to use redirect the user to the page of filtered users, I dont understand how I could carry over the ?search=harry url value to my SearchUserView view. A good visual example is how github implements this. in the url they have search?q=harry where it would show the filtered repo page with harry in the name. If I were the click on Users button on the side navbar, it would then show the url being search?q=harry&type=users with the filtered users page Although I'm not trying to completely copy github, I essentially just want to know how to keep that url query in different views. Thanks! -

Save file with Django Model to JSONField
I need to save files, but the number of files is uncertain, and in one request I can add a file, then in another request post, I can add one more file ... For this reason I thought that creating a JSONField type field could help me in this matter, but I don't know if it is possible and if it is possible I have no idea how to implement it in Django. Here is an example of how I currently upload a single file to Django Model: import uuid import time from users.models import User from django.db import models def upload_location(instance, filename): filebase, extension = filename.split('.') milliseconds = int(round(time.time() * 1000)) return 'events/thumbnail_images/%s__%s__%s.%s' % (instance.user_id, instance.name, milliseconds, extension) class Test(models.Model): id = models.UUIDField(primary_key=True, unique=True, default=uuid.uuid4, editable=False, null=False) image_link = models.FileField(upload_to=upload_location) user = models.ForeignKey( User, null=True, blank=False, on_delete=models.CASCADE ) As I'm using Postgres relational database, and I'm not sure how many files the user will want to save, I figured using JSONField, so that as the user adds files, the 'path+filename' is also added. It's possible? How to make? -

Django login error, LOGIN_REDIRECT_URL is not working

Best way to display a field site-specific using the Django Sites framework
