Do I need cstf protection when backend and frontend have different domains?
I have: React app: https://myreact.com Django + DRF: https://mydjango.com React has a form that when submitted sends a POST request to mydjango.com/handle-form with all the cookies, because I speicfy withCredentials: true in my ajax request (thus all the cookies are sent). As I can see it, there's no way to perform csrf attack, because browser stores cookies only for myreact.com. And if an attacker creates a domain myreact2.com with the same exact form (that upon submitting sends POST request to mydjango.com/handle-form), cookies from myreact.com won't be sent, meaning there's no csrf attack. The questions: Am I right? Will browser store cookies only in myreact.com or in both domains, when I make an ajax request from myreact.com to mydjango.com and mydjango.com in response sends a Set-Cookie header? I understand how it would work, when both frontend and backend shared the same domain. CSRF attack could be very possible without csrf token or something else. But my case bothers me. -

How do I add another field to my model without getting an error?
I added another field to my Listing() model called highest_bid. However, when I try to look at the listing model in the /admin page I get the OperationalError: no such column: auctions_listing.highest_bid After adding this field I tried using makemigrations, but it said that there were no changes and I also tried using migrate but that also said that there was nothing to migrate. I also tried removing null=True on the field but that did not change anything.

Remote Access to Django's Internet Server
I have a remote (virtual) Ubuntu development station, on which I installed Django, and on which I'm running "manage runserver". Now, I need to browse my project's URLs, and debug their view functions line by line. But I fail to remotely use the web browser on the remote development station (there was time that I succeeded doing so, but it was horribly slow). I therefore would like to enable the web browser on my own laptop to connect the web server of Django that's running on the remote development station. Is there a way to do so? -

MODELS.PY : class Question(BaseModel): class QuestionType(models.IntegerChoices): SINGLE_ANSWER = 1 MULTIPLE_ANSWER = 2 ESSAY = 3 CODE = 4 VIDEO = 5 UPLOAD = 6 class DifficultyLevel(models.IntegerChoices): EASY = 1 MEDIUM = 2 HARD = 3 question_text = models.TextField() type = models.IntegerField(choices=QuestionType.choices) level = models.IntegerField(default=1, choices=DifficultyLevel.choices) def get_absolute_url(self): self.get_type_display() def __str__(self): return truncatewords(self.question_text, 7) ADMIN : @admin.register(Question) class QuestionAdmin(admin.ModelAdmin): inlines = [ OptionInline, CodeInline, TestCaseInline, ] By this code all inlines(OptionInline,CodeInline,TestCaseInline) will be shown in admin page like the picture bellow: question admin panel pic but i want the inlines appear whenever the user choose the type, for example the OptionInline shows when user choose multiple_answer or CodeInline shows when user choose CODE from type dropdownlist what i did for this purpose is overriding the get_inlines method ADMIN : def get_inlines(self, request, obj: Question): if obj: if obj.type in [Question.QuestionType.SINGLE_ANSWER, Question.QuestionType.MULTIPLE_ANSWER]: return [OptionInline] elif obj.type == Question.QuestionType.CODE: return [CodeInline, TestCaseInline] else: return [] else: return [] but i have a problem when i want to change the type after saving the question this error appears : (Hidden field INITIAL_FORMS) This field is required.
