It's a fairly simple idea, but I'm not sure where I should start reading.
All I want to do is add an extra action to a model in the Django Admin.
For example, I have a basic client management system, in that I have models for Clients, Companies, and Invoices to keep track of who owes what. All I want to do is add an action or button that when used, pulls information from the Invoices, Clients, and possibly Companies and then puts that information into a PDF document.
Any suggestions?
You'll have to override your admin templates for each of your models to add a button => Overriding Admin Templates
To generate a PDF define a view that is called once your button is pressed. Make sure to set the right permissions for your admin users.

My use case is to implement something like a messaging form, allowing an administrator to write a message, then send it to group that they will filter from a list of users, from the User model. This is similar to the messaging to usergroups functionality in Joomla! so it's not too weird a use case.
So my admin page for the "Message" model would need to contain the Message creation form and a second recordset of site Users, which could be filtered down to those who the administrator wishes to contact.
Is this kind of thing possible in Django Admin, or do I need to dip into heavily customising an admin page?
I am working to achieve a flexible form region where a user can add additional forms. My tables are users and wallets, a user can have many wallets. The end goal is to allow a user to add as many wallets they would like in one page, to do this I will need to add Dynamic Forms. Normally in the MEAN stack, It is common for us to loop the form, so if a user clicks on a button it will generate a form and send the JSON Request as an array. I don't know how to get this done as I am a beginner in Oracle Apex
I'm still a complete newbie on Django, so now I'm a little bit lost on what I could do to structure my server to suit my needs.
The situation is like this: my Django admin could be accessed by the admin and multiple users. Each user can add multiple item to the server, and the server will only allow them to retrieve, modify and delete item added by them and not the other users. They will also have some custom option they can pick: like receiving notifications through emails or another channels. Meanwhile, admin can see all items, and have a filter to see all items added by one user and all users's custom option.
Any help would be appreciated.
take a look here. this is where i started with custom user models. https://wsvincent.com/django-custom-user-model-tutorial/
Django has builtin user models with basic fields like username email and password and authentication. The above link will help you create custom user models and it will be a good place to start
My web features two user types, Client and Professional. There are also two 'main modules', one for clients to buy stuff and so on (the main site), and the other for professionals to manage operations. For auth, I would like to have:
A single 'sign in' form, which detects whether the user is a client or a professional and forwards her to the right module (main site or management site).
Two 'sign up' forms, one for clients and other for professionals. Probably, the site will ask the user whether she wants to register as a professional or as a client, to trigger the right registration flow for each case.
Clients will use the 'main site' and should not be authorized to use the 'management site'.
Professionals will use the 'management site' but should not be authorized to sign in to the main site.
Both professionals and clients are registered as Users, and share common fields, such as username, phone, email, etc...
Since Django won't let me use two models for authentication. I've created custom model subclassing AbstractBaseUser and which serves me as a base auth class for Client and Professional.
class BaseUser(AbstractBaseUser):
...
class Client(BaseUser):
...
class Professional(BaseUser):
...
I've also changed the AUTH_USER_MODEL setting to:
AUTH_USER_MODEL = 'myapp.BaseUser'
I've also included django-allauth to manage user registration and authentication. But now I'm stuck. I just began playing with Django/Python and I'm not sure how to solve this.
It seems there is no official recommended way for doing this (Implementing multiple user types with Django 1.5). Should I stick to the subclassing approach, or should I do the OnetoOne relationship pointed out in the docs ?
Once I have the models properly setup, how should I proceed with the two registration forms? Is it possible to accomplish this with django-allauth, or do I need to do it manually?
As far as I know, when a new user is registered, a new base user is created in the User table. But since I will be creating user specializations (Client or Professional), how should I specify that I also want to create the client-related data or professional-related data in the corresponding table?
I'm pretty new to Django, so any advise will help
I think the easiest way for you to do what you are talking about is going to be to have 3 apps in your project: your top level app, a "professional" app and a "client" app. At the top level app, all you really need to do is give the users a login form, and 2 links, one for registering as a Professional and one for registering as a Client.
In this case, I believe it will be easiest for you to use Django's built in Permissions system, and assign each type of user to a corresponding group (eg. professionals and clients). You can use a decorator on your views to ensure that only members of a particular group can access that view (since you have 2 separate apps for each group, you can add a decorator to all views in each of them, or you can import Django's authorization functions into your urls.py and check it there, although that is beyond the scope of this answer).
Registration is easy enough, use your urls.py file to forward the user that wants to register to the correct app. Once you do that, you should be able to use django-allauth registration on each app, allowing you to create 2 different kinds of users. Make sure when the register, you assign them to the correct group membership.
As for the login redirection, once you receive the POST data, I would check for which type of user logged in, and use that to forward the user to the correct URL that goes with the Professional or Client app. You can see the below link for an idea of redirecting a user after login.
Django - after login, redirect user to his custom page --> mysite.com/username
In my Django app a user can register to the site and receive staff_user privileges from the admin.
After that the staff user can create and manage some other users (normal users) using default django admin site.
Now, I would like to let the staff user see and manage only the users he created from the admin site, I don't want him to see other users created by another staff user.
how can I do that? I imagine I need to modify admin.py right?
Don't modify the admin site.
In general, you have the following tools available:
Create groups
Add users to groups
Create custom permissions on your models, to indicate certain actions
https://docs.djangoproject.com/en/1.4/topics/auth/#custom-permissions
However, what you are asking: Now, I would like to let the staff user see and manage only the users he created from the admin site is not possible in django-admin.
The Django-admin site is only intended as a glorified development tool for fully trusted users, not as a customizable app for end users.
If your project requires an admin site with any of the following ...
Customized administraion functionality.
Exposure to any user that is not completely trusted.
... then I'm afraid you have to create your own custom app.
You can replace the stock UserAdmin with your own which overrides queryset() and does the filtering. The bigger issue is what to filter by. The default User model does not store a "created_by" in the model instance. So you would need to add this information whenever a User is added.
How best to do this depends on your Django version.
Django 1.5 introduced a "Configurable User model" which makes this very easy.
https://docs.djangoproject.com/en/dev/releases/1.5/#configurable-user-model
In earlier versions you would either have to monkeypatch the User model, or store that information in a separate "user profile" attached 1:1 to the User.
https://docs.djangoproject.com/en/dev/topics/auth/customizing/#extending-the-existing-user-model
Regarding the trusting of users (which wasn't a topic but I feel the need to comment on thnee's answer) in the Django admin, check out the links in my answer here: Should I use Django's Admin feature?
