Django model creating new migration after change in model choices
I have a model named UserRole and there is a field role, in which choices are present to select the role. The problem is that whenever I am adding a new choice and running makemigrations, django creating a new migration for that. I don't want a new migration everytime I add a choice. I know about ForeignKey, but in my case there will be at most 10 choices. Right now I have 3 predefined choices. How can I add choices without creating a new migrations? models.py class UserRoleModel(BaseModel): ROLE_1, ROLE_2, ROLE_3 = 1, 2, 3, USER = 'user' SUPPORT = 'support' ANALYST = 'analyst' CHOICES = ( (ROLE_1, USER), (ROLE_2, SUPPORT), (ROLE_3, ANALYST), ) user = models.ForeignKey(get_user_model()) role = models.SmallIntegerField(choices=CHOICES) migration file class Migration(migrations.Migration): operations = [ migrations.AlterField( model_name='userrolemodel', name='role', field=models.SmallIntegerField(choices=[(1, 'user'), (2, 'support'), (3, 'analyst'), (4, 'lol')]), ), ] I have removed redundant code. -
Wagtail manually login user
I have a wagtail application that needs to login and authenticate users for the /admin section using OAuth. The interaction with the OAuth provider works fine is just at the end of the authorize view I am getting a Too many redirects error. Here is my gist: SESSION_KEY = 'access_token' oauth = OAuth() oauth_client = oauth.remote_app(#oauth client setup here) Views def login(request): """ This view is redirecting to my oauth provider, log the user and redirect back to /authorize with the data in the request. """ return HttpResponseRedirect(oauth_client.authorize( callback='http://localhost/admin/authorize')) def authorize(request): resp = oauth_client.authorized_response(request.GET) request.session[SESSION_KEY] = (resp['access_token'], '') data = baton.get('/oauth/me') username = json.loads(data.data).get('username') user, _ = User.objects.get_or_create( username=username, defaults={'password': username, 'is_superuser': True} ) auth_user = authenticate(username=username, password=username) login(auth_user) return HttpResponseRedirect('/admin') Urls urlpatterns = [ url(r'^admin/login', login, name='login'), url(r'^admin/authorize', authorize, name='authorize'), url(r'^admin/', include(wagtailadmin_urls)), ] The Too many redirects I see in the browsers happens when the authorize view validates all the logic and tries to redirect to /admin but I think what is happening is that Wagtail then is redirecting again to /login but I though authenticating and login a user should be enough for Wagtail, apparently not. Any ideas how to overcome this issue, or programmatically login a user … -

Using multiple Django forms in single View which are dependent through OnetoOneField/ForeignKey
I have two models:- class User(AbstractUser): is_customer = models.BooleanField('customer status',default=False) is_manager = models.BooleanField('manager status',default=False) def __str__(self): return self.username class Customer(models.Model): user = models.OneToOneField(User,on_delete=models.PROTECT,primary_key=True,related_name="customers") full_name = models.CharField(max_length=264,) roll_no = models.IntegerField() mobile_no = models.IntegerField() hostel = models.CharField(max_length=264) room_no = models.CharField(max_length=264,) Here Customer's user object is dependent on the User model. forms.py:- class UserCreateForm(UserCreationForm): class Meta: fields =('username','email','password1','password2') model = User def __str__(self,*args,**kwargs): super().__init__(*args,**kwargs) self.fields["username"].label ="Display name" self.fields["email"].label = "Email address" class CustomerForm(forms.ModelForm): class Meta: model = Customer fields = ['full_name','roll_no','hostel'] What I want is to take Customer's details along with User details.

Unable to insert the data into model users group
I have created a custom User model in Django app users_and_auth to use the default authentication of the Django. models.py class Users(AbstractBaseUser, PermissionsMixin): email = models.EmailField(max_length=255, unique=True) first_name = models.CharField(max_length=255, blank=False, null=False) last_name = models.CharField(max_length=255, blank=False, null=False) profile_picture = models.ImageField(upload_to='profile_pictures/', max_length=None, null=True, blank=True) is_active = models.BooleanField(default=True) objects = managers.UserManager() USERNAME_FIELD = 'email' I want to categorize registered users in two different user groups say x and y. So, I added two new records in Group model of auth app i.e auth_group which was created when I run the first migration of the app. Then I run the migration of app users_and_auth which created 3 new models users_and_auth_users, users_and_auth_users_groups and users_and_auth_users_user_permissions. Now, these are the tables of database - As, shown in screenshot there is table in database called users_and_auth_users_groups which categorize users in groups listed in table auth_group. The table is described as below - I want to push the user_id and group_id in this database table from an APIView. What I don't understand is which exact app or model I will have to import so that I could use model.object.create(). -

How to create a fillable and savable pop-up form in Django project?
How do I trigger a fillable pop-up when the user clicks on an image, on a Django web app that the winds up sorting the following result ? There many features that come after that as shown in here, that can wind up like that, and resulting on this final result, but so far I couldn't find a solution to that first step (my sole focus) on other websites. Is this something that can be done with HTML, CSS, and JS only, or do I have to use python to then save the data to the SQLite database ? If someone can suggest or hint at the steps that I need to follow to get this done I would really appreciate it. -

Cannot populate database table during Heroku deployment?
I have a django app that runs perfectly well on my local server. Unfortunately, when I deploy it onto Heroku, the behaviour doesn't work as expected. I can see that it's a database related issue as my dropdowns which are supposed to load a list of values from my database are empty in production. I have checked on Heroku in the 'Ressources' section of my application and there is a database; it also contains all my project tables (django default tables + my main table). All the django default tables are properly populated (I compared them with my local postgres tables and it matched). Unfortunately, my main table is empty on Heroku, whereas it is populated as expected locally. I'm not sure to understand what has gone wrong, especially considering that the table itself has been recognized, yet it is empty. I've applied the command heroku run python manage.py migrate but it didn't fix the issue. My guess is that my database settings are correct for local deployment but not for Heroku deployment. Nevertheless, I'm not sure at all. I've tried replacing my db settings by the user/host/password/name provided by Heroku but it didn't work. Any guidance will be much … -

Django Reverse Not Found when reversing a url in main app
I can not get my head around why this simple reverse() call for one of my Django-Views is not working. The error occurs in some of my tests: Reverse code snippet: # myapp/tests.py response = self.client.get(reverse('index', args=([element1],))) URL registry: # myapp/urls.py urlpatterns = [ path('', views.index, 'index'), path('configuration/', include('configuration.urls')), path('admin/', admin.site.urls), ] view: #myapp/views.py def index(request): elements_list = DB_ELEMENTS.objects.all() return render(request, "startpage.html", {'elements': elements_list}) The error I keep getting is Reverse for 'index' not found. 'index' is not a valid view function or pattern name. Any help appreciated. -
Integrate CoreUi React Template and python (Flask or Django)
I'm very new to CoreUi and I'm trying to connect CoreUi (Frontend) and Python (Backend) but everything I tried didnt work.. Does anyone of you know a good video or documentation which could help me ? I integrated React and Python (Flask) before in another project a couple of month before where I used this instruction from youtube: https://www.youtube.com/watch?v=YW8VG_U-m48&t=179s . I tried to integrate CoreUi and Flask the exact same way but it didnt work. I dont care if I use Django or Flask, I only want the connection to work... I also deleted the code where I tried to connect the frontend with the backend so I cant give you any code snippets or my webpack.config file. Hopefully anyone can give some instructions to simply connect the coreUi Template to python. I downloaded the coreUi template from GitHub (https://github.com/coreui/coreui-free-react-admin-template) -
