How to change user password not in a separated view?
I want to let user change his password and edit his profile on the same page.

Django: list User details and Group for every User-Group (Many-To-Many) relationship in template
How to query and show User info and their Group for every User-Group (Many-To-Many) relationship in Django template? The result should look like: | User username | User email | Group name | | ------------- | -------------- | ----------- | | user1 | user1@mail.com | groupA | | user1 | user1@mail.com | groupB | | user2 | user2@mail.com | groupA | | user2 | user2@mail.com | groupC | | user3 | user3@mail.com | groupA | My question is similar to Vanilla Django Query to show 'flattened' User/Group (ManyToMany) Listing, but would like show more user details on the table. I naively thought something like this would have worked, but didn't. {% for group in groups %} {% for user in group.users.all %} <tr> <td>{{user.username}}</td> <td>{{user.email}}</td> <td>{{group.name}}</td> </tr> {% endfor %} {% endfor %} Using the raw SQL query has solved my problem: https://stackoverflow.com/a/38780451/991505 , but I am looking for better answers in the Django/Python way. -
