Why do I fail Django migration in heroku server while succeeding in local server?
So I have deployed my Django project to Heroku, and now trying to migrate the database. I have everything working fine in my local sever. Then I tried to run the commands in heroku, as below. python manage.py makemigrations This worked fine. Migrations for 'app_name': contents\migrations\0001_initial.py - Create model Book - Create model Category - Create model Content Then of course, I tried : git add .git commit -m "migration" git push heroku master heroku run python manage.py migrate app_name But then I got this error CommandError: App 'app_name' does not have migrations. Strange thing is, after running python manage.py migrate, everything works fine in my local server. It's only the heroku server where the error occurs. I've done some research for possible issues, none of which were relevant to mine. For example I do have init.py in the migrations folder inside app_name directory. Also, I've tried heroku run python manage.py migrate as well as heroku run python manage.py migrate app_name but neither worked. I'm very confused. What do you think is the problem? Thanks in advance. :) -

Django REST Framework: Updating via UpdateAPIView vs RetrieveUpdateDestroyAPIView / Prefilled Form in Browsable API
When I try to update a model instance via the generics.RetrieveUpdateDestroyAPIView I can see the instance's values prefilled in the form in the browsable API. However, when I use generics.UpdateAPIView I can't. Is this due to the fact that UpdateAPIView does not allow GET methods, so the view can't get the data to prefill the form or is there a special setting I need to add in my generics.UpdateAPIView to have the form prefilled automatically -

Deploying Django on IIS and ngrok
I am trying to deploy Django on local host and "tunnel" using ngrok. The ngrok works but the IIS (Internet Information Manager) gives 500 Error <handler> scriptProcessor could not be found in <fastCGI> application configuration. Reference into fastcgi shows that this feature is deprecated but what is the replacement for serving Django using local server and ngrok. I also pip installed pyngrok. Can you suggest a clear solution? -

Password is not saving to data base after hashing
I am creating user registration api in django_rest_framework. I created a serializer and class view. but there is some problem with password. I use Registration class which inherits CreateAPIView to create user-registration and user a ModelSerializer to serialize it. Before saving the data, I validate email and passwords.

Django - updating user account breaks the user password
I'm trying to set up an account update form, where a user can update its info but only when he/she provides its password at the end of the form. Unfortunately, when I try to update it (even with a correct password), I get logged off and I cannot log back in. I don't know why, but the password breaks completely and I have to reset it via shell. Also, when I look into the database, the password for each user that I tried to update, it's not hashed anymore, it's just in plain text. forms.py class UserProfileForm(forms.ModelForm): username = forms.CharField(label="Username", min_length=4, max_length=50, help_text="Required") email = forms.EmailField( label="Email", max_length=100, help_text="Required", error_messages={"required": "Sorry, you will need an email"}, ) password = forms.CharField(label="Password", widget=forms.PasswordInput) class Meta: model = UserAccount fields = [ 'username', 'email', 'first_name', 'last_name', 'about', 'password' ] def __init__(self,*args, **kwargs): super(UserProfileForm, self).__init__(*args, **kwargs) self.fields["username"].widget.attrs.update( { "class": "card bg-dark text-light form-control mb-3", "id": 'profile-username' } ) self.fields["email"].widget.attrs.update( { "class": "card bg-dark text-light form-control mb-3", "id": 'profile-email' } ) self.fields["first_name"].widget.attrs.update( { "class": "card bg-dark text-light form-control mb-3", "id": 'profile-first_name' } ) self.fields["last_name"].widget.attrs.update( { "class": "card bg-dark text-light form-control mb-3", "id": 'profile-last_name' } ) self.fields["about"].widget.attrs.update( { "class": "card bg-dark text-light form-control mb-3", "id": 'profile-about' … -

how to make a char field behave like URLField in django

Add more than 1 folder (network path) to static files with Django on IIS
I have a django website deployed on an IIS Server. in it, I have 2 different network paths I need to access via static STATICFILES_DIRS = [ "//server1/Shared1/folder/", "//Server2/folder2/", ] Now, currently my IIS has a static virtual directory that is set to "server1" this allows me to work with all the files I have in that shared network drive and opertate properly. The issue comes when I try to work with any files in the "server2" I don't know how to add it. I understand that exists something called "static root" but for that I need to do a "collect static" in this case, I can't do a collect static since both servers have over 60gb of data that I need to access. Is there a way I'm not seeing for adding this second server to be able to be used via IIS? -
How to apply multiple filters in a Django query without knowing if some filters are null or not
Let's say we have the following filters: filter1 = request.GET.get("blabla") filter2 = request.GET.get("blabla") filter3 = request.GET.get("blabla") filter4 = request.GET.get("blabla") filter5 = request.GET.get("blabla") filter6 = request.GET.get("blabla") Let's say we have the following query: user_projects = Project.objects.filter(element1=filter1, element2=filter2, element3=filter3, element4=filter4, element5=filter5, element6=filter6).distinct().values("id", "name", "customer_id", "dev_status", "manager_id", "total_billable") Some of the filters might be of type None (depends on the request) I would like to create a dynamic query that based on whether the filter exists or not, executes the query only with the non-null filters. Let's say for example filters 1, 2, and 3 have values, but filters 4, 5, and 6 are empty/null/None. Expected query: user_projects = Project.objects.filter(element1=filter1, element2=filter2, element3=filter3).distinct().values("id", "name", "customer_id", "dev_status", "manager_id", "total_billable") What I've tried: if filter1 is None or filter1.strip() == "": filter1 = "" elif is_valid_queryparam(filter1): user_projects = Project.objects.filter(element1=filter1).distinct().values("id", "name", "customer_id", "dev_status", "manager_id", "total_billable") And it works, but only for one filter, if I want that for 6 or N filters, it's extremely inefficient to execute multiple queries. Is it possible to achieve the desired result with a simple query? -

Why are django-q scheduled tasks delayed randomly?
I'm finding that django-q is not executing tasks I schedule on time. There can be delays of several seconds to almost a minute.
