How to change form field label in Django using template language only?
I have tried using django-widget-tweaks to override default form field attributes, where you can set various form field attributes like this: {{ form.username|attr:"name:email"|as_crispy_field}} but when I inspect the element in the Chrome Dev Tools I can see that the element still has the default username name attribute. I was trying to change the name attribute so that the label for this field would display "Email" instead of "Username". So I was wondering if there is a way to change Django form field label using Django template language only? 3rd party tools are OK too. -
Group by specific attribute in Django using ORM
I have a model as below: class Revenue(BaseModel): revenue_type = models.ForeignKey(RevenueType, blank=True, null=True, max_length=256, on_delete=models.SET_NULL, related_name='revenue') external_account_id = models.CharField(blank=True, null=True, max_length=256) external_user_id = models.CharField(blank=True, null=True, max_length=256) Now I want to get all the revenues ids but grouped by similar external_account_id. Suppose the below are the model instances details: revenue1 = Revenue("external_account_id": 1, "external_user_id": 1) revenue2 = Revenue("external_account_id": 1, "external_user_id": 2) revenue3 = Revenue("external_account_id": 1, "external_user_id": 3) revenue4 = Revenue("external_account_id": 1, "external_user_id": 4) revenue5 = Revenue("external_account_id": 2, "external_user_id": 5) revenue6 = Revenue("external_account_id": 2, "external_user_id": 6) revenue7 = Revenue("external_account_id": 3, "external_user_id": 7) revenue8 = Revenue("external_account_id": 3, "external_user_id": 8) revenue9 = Revenue("external_account_id": 4, "external_user_id": 9) revenue10 = Revenue("external_account_id": 5, "external_user_id": 10) I want the queryset or dict like this: {1: [1, 2, 3, 4], 2: [5, 6], 3: [7, 8], 4: [9], 5: [10]} Where the keys are the external_account_id and the values are either external_user_id or ids of the model instances. How can I query for the same? -

"Change password system" does not work in user authentication.(Django)
I'm trying to configure Django app with a user authentication model(django-allauth). It almost works well but when a user tries to change his password, a problem occurs. Let's say when a user want to change his password, he goes to Password reset page Example http://3.129.xx.xxx/accounts/password/reset/ He put his Email address on the form and submit, then he recieve a "Password Reset E-mail" with a link to reset the password. Example https://u22207100.ct.sendgrid.net/ls/click?upn=EGpFlOkd4a3JZnFjHjqKqsCiiinSf51vqFvV..... Cliking above link, the user redirected to http://3.129.xx.xxx/accounts/password/reset/key/1-set-password/ But that page has only links "Sign In" and "Sign Up". It does not have any form to put new password the user want to set. Change password page's image In this situation, the user can not change password. should I set something to allauth system?? I just mentioned the above settings in this question but still if more code is required then tell me I'll update my question with that information. Thank you -

i am trying to implement a Paypal payment system.

I am trying to modify a user's username in his profile. I'm not using Django's User model and had created a custom user model (MyRegistration) by inheriting AbstractBaseUser.

why my remote server not able to connect to postgres instance on another Django server?
I have two Ubuntu server A and B. Initially I had Django, postgres, celery on single server A. Everything was working fine. Now A has Django, postgres, and B has celery and Django project installed. DB migrations are done on A, and database connectivity is proper on A. This I can say that because when I am trying to start the celery server on server A, I am able to successfully launch the celery through the command prompt. No problem. As per the requirements, I have to only run Django and postgres on server A, and Celery on server B. Since I am using the same Django server settings on server B that I have in A, so the Django settings.py has the same DB connectivity settings as shown below. i.e. the DB settings are same on A and B DATABASES = { 'default': { 'ENGINE': 'django.db.backends.postgresql_psycopg2', 'NAME': 'xyz', 'USER': 'smthing', 'PASSWORD': 'smthing', 'HOST': 'some_IP', 'PORT': '5432', } } To see if the postgres is running or not on server A. I executed the service command $ service postgresql status ● postgresql.service - PostgreSQL RDBMS Loaded: loaded (/lib/systemd/system/postgresql.service; enabled; vendor preset: enabled) Active: active (exited) since Thu 2021-06-10 10:57:11 IST; … -
