Implementing reset password for different user app in django
PLease I have two two apps that handle two kinds of users in my project. The two kinds of user have different privileges on the site (I also have groups based on these two user account apps). The problem am having is that the default. from django.contrib.auth import views as auth_views has only one file structure in contrib/admin/templates/registration. I have this in urls.py for the diferent apps: path('reset_password/', auth_views.PasswordResetView.as_view(template_name="users/reset_password.html"), name="reset_password"), path('reset_password_sent/', auth_views.PasswordResetDoneView.as_view(template_name="users/password_reset_sent.html"), name="password_reset_done"), path('reset/<uidb64>/<token>/', auth_views.PasswordResetConfirmView.as_view(template_name="users/password_reset_form.html"), name="password_reset_confirm"), path('reset_password_complete/', auth_views.PasswordResetCompleteView.as_view(template_name="users/password_reset_done.html"), name="password_reset_complete"), For the second app, I have this in the urls.py path('reset_password/', auth_views.PasswordResetView.as_view(template_name="companyusers/reset_password.html"), name="reset_password"), path('reset_password_sent/', auth_views.PasswordResetDoneView.as_view(template_name="companyusers/password_reset_sent.html"), name="password_reset_done"), path('reset/<uidb64>/<token>/', auth_views.PasswordResetConfirmView.as_view(template_name="companyusers/password_reset_form.html"), name="password_reset_confirm"), path('reset_password_complete/', auth_views.PasswordResetCompleteView.as_view(template_name="companyusers/password_reset_done.html"), name="password_reset_complete"), but django does not seem to find the template paths unless I put the html files in the general templates folder for the project thus: path('reset_password/', auth_views.PasswordResetView.as_view(template_name="reset_password.html"), name="reset_password"), path('reset_password_sent/', auth_views.PasswordResetDoneView.as_view(template_name="password_reset_sent.html"), name="password_reset_done"), path('reset/<uidb64>/<token>/', auth_views.PasswordResetConfirmView.as_view(template_name="password_reset_form.html"), name="password_reset_confirm"), path('reset_password_complete/', auth_views.PasswordResetCompleteView.as_view(template_name="password_reset_done.html"), name="password_reset_complete"), So when a user resets to password, the final login page points to just the login page for one user. Meanwhile the two apps in the project has two different login pages. when I try to use url name-spacing for the reset password url paths, django is not able to find them since they are not in the root directly.

How to change Django static files
I know this might be a really obvious question, but I'm doing a Django project where I have Javascript in my static files. However, I have noticed that whenever I make a change to those files, my web server doesn't reflect the changes. Is there some migration or something else I need to do to make my web server reflect changes to my static Javascript files? Thanks. -

How can i set permission on url
I am new on Django, I have implemented a valid form and now i want to set permission on url. When a form is submit then it redirects me to this url http://127.0.0.1:8000/success/. Without submitting a form i can manually type the name of the url "http://127.0.0.1:8000/success/" and it will take me to the same page.

Django: can I make db queries async?
In my app I have a template that I wish to make it like a control center that would display a ton of information, so I have to make a ton of queries to grab that info. So of course, the page is slow as heck and now I'm thinking how to fix this. I thought about making indexes but I don't have the space for this. I already optimized my queries to the minimun waste possible but it still takes like 1:30 minutes to load the page. I'm looking into assynchronous support on Django, but the version of Django I'm using doesn't seem to support (2.1). Does anybody got any tip that could help me in this? I didn't showed my code because I figured it's not nescessary, for this question is more abstract. It's not about my problem especifics but more about optimization in general. -
Django: make an addition inside of a model.objects.filter.update()
I have this view that has a form and I want to update a field of a model based on the user input. I cannot find a way to do that. The pytonic way =+ does not seem to work in this situation.

Django: Can't add field to custom user model
So, I've got a well running Django 3 app with a custom user model running on a MySQl db. I've been doing makemigrations and migrate successfully for months. Today I tried to add a field to my custom User Model called Account. The second I add a field to that model, the dev server attempts to process the change and crashes with this error: django.db.utils.OperationalError: (1054, "Unknown column 'account_account.lifetimeuser' in 'field list'") Doesn't matter the type of the field or the name. The base exception is: MySQLdb._exceptions.OperationalError: (1054, "Unknown column 'account_account.lifetimeuser' in 'field list'") Understand that this is NOT at runtime. It's right after I change the model and stop typing. Or in this case uncomment the lifetimeuser field (BTW, this is for testing only. I know I have an is_lifetime_user. That's the real field that was added sometime ago. Also note that this is ONLY with the Account model. Every other model in the file works as expected. Add, remove, edit: no problem as long as the syntax is correct. Since the error happens immediately, I can't makemigrations or migrate. I know my DB is in sync everywhere else. Can anyone give me a hint as to what is … -
Different One-To-Many relationships with same entities in Django
How would one go about implementing two different One-To-Many Relationships between the same entities in Django? For example: Suppose we have two relationships between a physical movement and muscles involved. For each movement I want to be able to distinguish between its main acting muscles and its supporting muscles. In practice I would introduce two tables (movement2primarymuscle, movement2supportingmucsle) and create a row with foreign keys for each relationship in each table. What's the Django way of implementing this with Django models? -

(Django) Can you access model methods in Create & List View?
I have a StaffProfile Model and an Establishment Model. I'm using Class Based Views, and in each of the CRUD views for the StaffProfile Model I need to check that the User logged in is an admin at the Establishment the StaffProfile is a member of. To do this I have a get_establishment() method in the views and a UserIsAdmin mixin that checks the User is an admin of the Establishment. My question is: instead of having to copy and paste the exact same method in each view, can I put it in the model itself and then reference it? I know I can for DetailView, UpdateView, DeleteView... but for CreateView and ListView it doesn't work as there is no object to reference, so I'm wondering if there is another way to access the method? Or a different approach I should be taking? My Code (shortened & simplified): views.py # URL for view is: <slug:establishment_slug>/staff/create/ class StaffProfileCreate(LoginRequiredMixin, UserIsAdminMixin, generic.CreateView): form_class = CustomStaffProfileCreationForm template_name = 'profiles/create_staffprofile.html' login_url = "login" def get_establishment(self): establishment_slug = escape(self.kwargs.get('slug')) establishment = Establishment.objects.get(slug=establishment_slug) return establishment # URL for view is: <slug:establishment_slug>/staff/<int:staff_pk>/ class StaffProfileDetail(LoginRequiredMixin, UserIsAdminMixin, generic.DetailView): model = StaffProfile template_name="profiles/detail_staffprofile.html" login_url = "login" def get_establishment(self): establishment_slug = escape(self.kwargs.get('slug')) … -

Some fields are common to both the types of Users that I want my Django app to support and hence I add those fields in the extended User model. My User model is as follows. class User(AbstractUser): is_a = models.BooleanField(default=False) # a boolean flag to determine if this user is of type a is_b = models.BooleanField(default=False) # a boolean flag to determine if this user is of type b Name = models.CharField(max_length=128) Email = models.EmailField() MobileNumber = PhoneNumberField(null=False, blank=False, unique=True) Age = models.PositiveIntegerField() Gender = models.CharField(max_length=1, choices=GenderChoices) Organisation = models.CharField(max_length=128) Designation = models.CharField(max_length=128) def __str__(self): return self.Name I then make migrations.
