django oauth2 authentication with client_id and client_Secret hardcded
I implement Oauth2 in django and my refresh token is under o/token/ url, I want to define another url like this: path('api/v1/login',Login.as_view()), and inside my login view I want to have something like this: class login(APIView): def post(self,request): client_id = "123" client_Secret = "123" username = request.query_params.get('username') .... *problem is here* I want to define those parameters inside login class and then pass it to o/token/ url and get the token as a result. In fact, when the user enters www.example.com/api/v1/login address, it enters just username and password and previously inside my code I said to OAuth what my client info is and then the token will generate. -

Django is putting empty string by default while excepting it to be null
I am using postgresql version 10.6 with my Django 2.1 application. The problem is that when I am using null=True in my model field it is translating to empty string ('') in database column as default where I am trying default it as null. In my following code sample image column should be null: class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) image = models.ImageField(upload_to='profile_pics', null=True, blank=True) And I am calling this class from a signal like this: @receiver(post_save, sender=User) def create_profile(sender, **kwargs): if kwargs.get('created') is True: Profile.objects.create(user=kwargs.get('instance')) In this snapshot you can see that image column is inserting as empty string instead of null I have also tried to use default value for my model field as: image = models.ImageField(default=None, upload_to='profile_pics', null=True, blank=True) but it doesn't work either. -
problem with setting & accessing a variable value in django template
I want to set a variable err for errors in the form fields (using django 2.1.3): {% for field in form %} {% if field.errors %} {% with field.errors as err %}{% endwith %} {% endif %} {% endfor %} {% if err %} <div class="alert alert-danger fade show"> <button type="button" class="close" data-dismiss="alert" aria-label="Close"> <span aria-hidden="true">&times;</span> </button> {{ err }} </div> {% endif %} But, while rendering to html the value of the variable has no output. Though, there are errors, which I've raised using forms.ValidationError. Also, try this like ... {% for field in form %} {% if field.errors %} <div ... > ... ... {{ field.errors }} </div> {% endif %} {% endfor %} In this case, output or the errors are showing, but with multiple <div> elements & n no. of times. I know that, it can be done by another way in the views.py: using 'django.contrib.messages'. Then sending errors to messages.error(), inside form.is_valid(), then ... {% if messages %} {% for message in messages %} {{ message }} {% endfor %} {% endif %} But, I want to manipulate it from forms.py file. So, how do I do it? 🙄️😕️🤔️🤨️ Thanks in advance!! -
Django CKEditor 404 image not found
On my Django admin panel, I can upload an image using CKEditor. However, the image doesn't apear and it return a 404 not found on the image file path. Actually, my image files are available on a dedicated url : media.mysite.com But, CKEditor is trying to GET the file from mywebsite.com/media/uploads/..., so this is normal that I get a 404 error. What is the good parameter to do for telling to CKEditor to use media.mysite.com to get any images ? Settings.py MEDIA_ROOT = "/var/www/media/mysite/" MEDIA_URL = "/media/" CKEDITOR_BASEPATH = "/static/ckeditor/ckeditor/" CKEDITOR_JQUERY_URL = 'https://ajax.googleapis.com/ajax/libs/jquery/2.2.4/jquery.min.js' CKEDITOR_UPLOAD_PATH = 'uploads/' CKEDITOR_IMAGE_BACKEND = "pillow" CKEDITOR_CONFIGS = { 'default': { 'toolbar': 'full', 'height': 300, 'width': '100%', }, } I visited many topics, but I found no answer. Thank you. -

django2 migrations ProgrammingError
Since I moved from django 1.8 to 2.1 I frequently get db migration errors. It doesn't occur during the migration directly, but when manage.py is called: django.db.utils.ProgrammingError: relation "obj1_obj2" does not exist LINE 1: .... Migration doesn't even start but it defines the relation or any model changes that cause the errors. When working locally I usually rollback code and then make migrations, but on cloud providers it is useless solution. I work on python 3.6 -

authentication from mobile to backend django
Good day everyone. I am stumped at the moment and would appreciate some guidance. I feel like I am a great googler to usually find my answers or resources but for the life of me I can't seem to find any good learning material on JSON requests and responses. So I took a course that builds a 3 part app. Web app with Django, and 2 mobile apps that make API calls to it. The instructor uses Facebook authentication from the mobile apps and I am trying to set up the apps for username and login and a registration page as well. I have django models setup and and can make users from the web app but I can't seem to wrap my head around how to make JSON calls from app to Django. When I search for possible terms like authenticate django I get results that talk about only django usage. Does anyone have some tips or links to resources that would help me understand the login process better. I realize that almost every app has a login which is why I'm surprised that I can't find any good learning material on how its done. Or I'm just searching … -
