Need help using placeholders for auth_views in django
I created a forgot password functionality using django.contrib.auth.views which is working fine. However the styling does not go with the rest of the site. I want to use only placeholders for the form fields. But since I am using the mentioned view, i don't know how. I want to remove the Email label here and write that as a placeholder This is the general theme of the site: For the login and register pages, I am mentioning the fields separately as shown in the figure: If i try do that for my forgot-password page, I get this result with no visible fields. If I try using form.password1 and form.password2, it doesn't work and I don't get the form fields at all. Here i use only the form option. I want to have the labels as placeholders(no labels). And the other stuff removed. Here are the views used in the urls.py file: Is the view using the second form? Also is there an option for a redirect here so I can just redirect my users to login page instead of a separate page? please help -

Django returns only default image URL
I am new to Django and building a simple social media type app for adding and viewing posts. I am using admin side to upload profile images for users and it works well. I am yet to create a frontend to upload profile images. I am using PostgreSQL and I can query to see the correct URLs being saved in the table for profile images. But when I try to fetch these images and render, the default image (set in models.py) always renders. I am able to open the right images from admin side but Django only returns the default image. My frontend has Javascript in which I am using fetch API to get URLs of profile images. It works well except it returns only the default image. Please help me find out where I am going wrong or why only 'defaultpp.jpg' always shows up. I have tried using print statements in models.py and views.py and only see the URL for 'defaultpp.jpg' being returned. models.py def user_directory_path(instance, filename): return f'{instance.profile_user.id}/{filename}' class User(AbstractUser): def __str__(self): return f"User ID: {self.id} Username: {self.username}" class UserProfile(models.Model): profile_user = models.OneToOneField(User, on_delete=models.CASCADE, primary_key=True) profile_picture = models.ImageField(upload_to = user_directory_path, blank=True, null=True, default='defaultpp.jpg') def __str__(self): return f"User: {self.profile_user} …
