Django: csrf_exempt doesn't work when other server send request?
views.py class OrderPayCheckView(View): @method_decorator(csrf_exempt) def dispatch(self, request, *args, **kwargs): return super(OrderPayCheckView, self).dispatch(request, *args, **kwargs) def post(self, request, *args, **kwargs): return redirect(reverse("home")) I used 3rd-party service (I'm client) and it sends sort of Notification request(POST) to OrderPayCheckView. Since this POST request is not from my application, I thought that this view should be decorated with csrf_exempt so that it doesn't require csrf token anymore. When I tested with POSTMAN it works very well: it shows redirected template page as a response body. However, when this 3rd-party service(server) tried sending POST request to this view, it shows an csrf-token authentication errors like this: (Since errors are in Korean, I translate it) REQUEST HTTP BODY : imp_uid=imp_1234567890&merchant_uid=merchant_1234567890&status=ready REQUEST HTTP STATUS : 403 REQUEST HTTP BODY : <!DOCTYPE html> <html lang="en"> <head> <meta http-equiv="content-type" content="text/html; charset=utf-8"> <meta name="robots" content="NONE,NOARCHIVE"> <title>403 Forbidden</title> </head> <body> <div id="summary"> <h1>Forbidden <span>(403)</span></h1> <p> CSRF authentication failed. </p> <p> The reason this message shown up is that this https site require "reference header" from your browser, but didn't receive anything abuout it. This header is required for security.</p> </div> </body> </html> What's wrong with it? Do sender have to add specific reference header to its request? -

I know i could pass a parameter from the view that calls the template but i am not sure how I can set a value through a template that calls that template ? -

How to create a custom entry style for field in django admin
I have this project where i have to store two dates (month and year) in the hebrew calendar in a model and get the model if the current date is between the two. My solution to this is to store them as SmallIntegerFields in the database in the MMDD format so that I can do a quick search after converting the date. Is there any way for me to modify the admin display of this field to show two dropdowns one for the months and one for the dates? (and convert them back and forth on load and save) -

django reverse match problems
I have been trying to figure out why I'm having trouble with this. Everything seems to be fine, and I have no problems with other urls reversing. When I enter the URL manually, the page comes up fine. This is the template tag that causes the problems: {% url 'schedule:calendar' %} Here is urls.py: app_name = 'schedule' urlpatterns = [ url(r'^$', login_required(views.CalendarView.as_view(), login_url='/login/'), name='calendar'), ] I don't think it's necessary, but my views file has only this in it: class CalendarView(TemplateView): template_name = 'schedule/index.html' def get_context_data(self, **kwargs): context = super(CalendarView, self).get_context_data(**kwargs) context['template'] = 'calendar_view' return context I don't see naming conflicts at all, yet when I put {% url 'schedule:calendar' %} in my template, anywhere, it throws the error, even if that is the only thing in the template page.

use single-sign-on/remote-user authentication with django restframework to get authentication token
I have a django application implementing a REST API using the django-rest-framework. The authentication is to be implementated using apache/single-sign-on/remote-user method, for the non-API part of the URL Tree. and for the API portion of the tree we would like to use token based authentication. What is the simplest way to retrieve the authentication token, through a restframework APIview under the non-SSO protected part of the URL subtree. Using rest_framework.authtoken.views.obtain_auth_token seems to look for user/password in the json data. What is the best way of doing this using single-sing-on/remote_user, where the authentication is taken care of the apache. I was thiking there should be an existing authentication class that should help. But can't seem to find it. -
Django CSRF Error for Registration
I've thoroughly searched and applied code to the best of my current ability fixes to what solved other peoples similar problems, except I still get a 403 CSRF error when the user presses 'register' on my registration form, but admin login works. If any one can point me in the right direction it would be much appreciated. The things Ive tried and checked so far is: to put the CSRF middleware at the top of the middleware list, make sure the html registration form has {% csrf_token %}, make sure the register view contains render_to_response with RequestContext, and now im at a loss of what to try next.

Django template structure issues
I have a base.html template that every page on my site will be extending. However, from what I've gathered, Django requires that templates should be in the app directory. From an app, how can I extend a template that I have located in my project's basedirectory/templates/ ? Here is how my directories are ordered: project/ |----templates/ | |----base.html | |----app1/ | |----templates/ | |----app1/ | |----base.html | |----index.html | |----app2/... Currently, I have index.html extending app1/base.html: {% extends 'welcome/base.html' %} However, this is not ideal, because I want to extend project/templates/base.html. Logically, my app1 shouldn't have a template in it. -

Logging with email/password not with username using djangorestframework-jwt and django-rest-framework
I'm using rest-framework-jwt and just wanna know a few things. First, I make the login with the email and password, and I get the token. It works well. but I also wanna create a token in my register. so, I use this function: def create_token(user): jwt_payload_handler = api_settings.JWT_PAYLOAD_HANDLER jwt_encode_handler = api_settings.JWT_ENCODE_HANDLER payload = jwt_payload_handler(user) token = jwt_encode_handler(payload) return token The problem is that I don't have an username. So, it doesn't work. :) I thought, if it works with the login, it should work with the register. But not. :smiley: Even if I wrote this USERNAME_FIELD = 'email' in my model. It always asks for a username in my "create_token" function. But second, I would like to create the token with just the email, password, and uuid And third... Is the same token from my register and from my login? To make the requests, it should be the same. Thank you! -
