I have no idea how to do it. thanks in advance. -

Django Ajax form
I want to use Ajax in Django to handle the view of my checkout form after it has been submitted. After the form is submitted, I want it to go to : return HttpResponseRedirect(reverse(str(next_page))+"?address_added=True") , i.e http://127.0.0.1:8000/checkout/?address_added=True But for some reason, it is not going there. Rather it's being going to http://127.0.0.1:8000/checkout/?csrfmiddlewaretoken=W4iXFaxwpdtbZLyVI0ov8Uw7KWOM8Ix5GcOQ4k3Ve65KPkJwPUKyBVcE1IjL3GHa&address=123+Main+Street&address2=&state=MA&country=USA&zipcode=55525&phone=%28877%29+314-0742&billing=on As a result, the form data is also not getting saved. I was thinking if it were because of the new version of Django. What I want to do is that after they submit the place order button, the form is going to be None, i.e disapper and then I would add a credit card form there for payment. But it is not happening. What is wrong here? Can anyone please help me out of this or is there a better way to do this?

How to implement ownership roles for specific models through DRF
Have two types of models, User and Object. Each User can have different ownership level of Object which will come attached with different permissions when accessing DRF endpoints (ownership=ManyToManyField(Object, through='UserObject')). e.g. A User with ownership.permission='Owner' for Object would have CRUD permissions while a User with ownership.permission='Manager' would only have RU permissions while a User with no ownership would have only C permissions. I'm currently storing the relationship with two tables OwnershipLevel with M2M to Permissions which states which of the CRUD permissions the role has but every API transaction is DB heavy as I have to retrieve the user permissions at the beginning. Looking for a way to lessen the load on the DB if possible, by caching role permissions on load or something. Thank you! -

I have the following in history.html <table> {% for i in itemsid %} <tr> <td>{{ i }}</td> ... but I don't know how to code it (how to loop it) to show the table with the lists as source.
