Django custom user createsuperuser

Many projects choose to use a custom user model from the start of their development, even if it begins as a copy of the default model, in order to avoid the difficulty of migrating to a custom user model later on. In general, django-registration will work with a custom user model, though at least some additional configuration is always required in order to do so.

Django provides a number of helpers to make it easier for code to generically work with custom user models, and django-registration makes use of these. However, the built-in registration workflows must still make some assumptions about the structure of your user model in order to work with it. The two-step activation workflow requires that the following be true of your user model:.

The one-step workflow places the following requirements on your user model:. The base RegistrationView contains code which compares the declared model of your registration form with the user model of your Django installation. If these are not the same model, the view will deliberately crash by raising an ImproperlyConfigured exception, with an error message alerting you to the problem.

This will happen automatically if you attempt to use django-registration with a custom user model and also attempt to use the default, unmodified RegistrationForm.

In the case where your user model is compatible with the default behavior of django-registration, you will be able to subclass RegistrationFormset it to use your custom user model as the model, and then configure the views in django-registration to use your form subclass.

For example, you might do the following in a forms. You may also need to specify the fields to include in the form, if the set of fields to include is different from the default set specified by the base RegistrationForm. Then in your URL configuration example here uses the two-step activation workflowconfigure the registration view to use the form class you wrote:. If your custom user model is not compatible with the built-in workflows of django-registration, you have several options.

One is to subclass the built-in form and view classes of django-registration and make the necessary adjustments to achieve compatibility with your user model. Finally, it may sometimes be the case that a given user model requires a completely custom set of form and view classes to support.

The process for using a custom user model with django-registration can be summarized as follows: Compare your custom user model to the assumptions made by the built-in registration workflows. If your user model is compatible with those assumptions, write a short subclass of RegistrationForm pointed at your user model, and instruct django-registration to use that form. If your user model is not compatible with those assumptions, either write subclasses of the appropriate views in django-registration which will be compatible with your user model, or modify your user model to be compatible with the built-in views.

These steps are covered in more detail below.

The username and email fields must be distinct. If you wish to use the email address as the username, you will need to write your own completely custom registration form.

Read the Docs v: 3.Opened 8 years ago. Closed 8 years ago. There is a dependency in the createsuperuser management command on the existence of a field called 'username' in a user model. Since was fixed, user models do not necessarily have that field. As a result, if syncdb installs django. I have a one line patch which fixes this, and will try to get tests written for it later today. Please feel free to mark this as invalid if that's the case, and I'll add a note to the docs instead :.

However, that interpretation does mean that you wouldn't be able to create a model like this:. It's an edge case, but one that we can easily get around by not constraining the parameter names in the manager methods. It also assumes that there's a username. If you can find a way, that's great. Clarifying in the docs that these commands currently only work with User models that look a lot like the default model is easy and easy to approve.

If neither of those are specified, you will get an error that username field does not exist, which could be the problem being experienced? At that point I ran syncdb on a brand new database. However, then it calls SocialUserManager. That failed, of course, since the method I wrote required an 'email' parameter instead. As I said in comment:1absolutely feel free to close this as invalid; what I wrote was not what was in the instructions.

Right now, from my reading of the code I haven't tested this or run into it in a real situation, it looks like we have an undocumented restriction on user model fields:. The issue is that creating superusers with a 'username' has been around a while - so we can't change the signature of that method without breaking backwards compatibility. I generally prefer the explicitness of passing named kwargs rather than positional - as there is less chance for mistakes assuming the first position is one thing when it is something else.

I do agree this particular detail of legacy needs to be highlighted in the docs - and I'm considering a major refactor of the auth docs currently. That was the subtle point that I didn't pick up in the docs originally. In that case, though, the docs definitely need to be clearer about the exact method signature. No, I stand by my point. If you try to run manage.How do I fully replace the username field with an email field for Django authentication?

This post explains step-by-step how to create a custom User model in Django so that an email address can be used as the primary user identifier instead of a username for authentication. Keep in mind that the process outlined in this post requires significant changes to the database schema. Because of this, it's only recommended for new projects.

If this is for an existing legacy project, you'll probably have to back up the data and recreate the database. For more on this, review the following resources:. The default User model in Django uses a username to uniquely identify a user during authentication. If you'd rather use an email address, you'll need to create a custom User model by either subclassing AbstractUser or AbstractBaseUser.

It's highly recommended to set up a custom User model when starting a new Django project. Without it, you will need to create another model like UserProfile and link it to the Django User model with a OneToOneField if you want to add new fields to the User model.

Feel free to swap out virtualenv and Pip for Poetry or Pipenv. DO NOT apply the migrations. Remember: You must create the custom User model before you apply your first migration. First, we need to add a custom Managerby subclassing BaseUserManagerthat uses an email as the unique identifier instead of a username.

Add the following line to the settings. Now, you can create and apply the migrations, which will create a new database that uses the custom User model. Before we do that, let's look at what the migration will actually look like without creating the migration file, with the --dry-run flag:.

Django Custom User Model

Make sure the migration does not include a username field. Then, create and apply the migration:. Refer to Referencing the User model from the official docs for more info. Also, when you create a superuser, you should be prompted to enter an email rather than a username:. That's it. Run the server and log in to the admin site. You should be able to add and change users like normal.

In this post, we looked at how to create a custom User model so that an email address can be used as the primary user identifier instead of a username for authentication. You can find the final code for both options, AbstractUser and AbstractBaseUserin the django-custom-user-model repo. The final code examples include the templates, views, and URLs required for user authentication as well. Generated by Django 3. Unselect this instead of deleting accounts.

A user will get all permissions granted to each of their groups. System check identified no issues 0 silenced. Recommended Tutorials.It is the mechanism for identifying the users of your web application.

A user will log in by providing their username and password. Then depending on your authentication backend the identity of that user is preserved across requests either through a session, a token, or some other mechanism. When a request is made to your web application, Django loads an instance of the User model that represents and identifies the user of your web application.

Making a Custom Django User Model Tutorial

All the fields on the built-in Django User model are used for authenticating the user, communicating with the user, and understanding what the user is authorized to access. Most Django projects have application-specific data associated with a user, such as a profile image or application preferences.

Data like this could be stored or associated directly via the model, or you could alternatively create a Profile model that stores the application-specific data. There are a few advantages to storing application-specific data on the User model. There are fewer objects you need to keep track of and fewer objects that you need to load from the database.

Anything your application needs to know about the user and their preferences can easily be stored and accessed in a single place. The risk here is that your model ends up being bloated with extra fields that you may not always need to apply to every user in the system, which can make your user table in the database a little unwieldy.

The alternative to keeping this data is to store application-specific data on another model that has a one-to-one relationship with the User model. This keeps your model simple, lean, and authentication-specific. When application data is separate from authentication data, the decoupling makes it easier to make changes in the future. Although, depending on your application, it could be worth it.

Another reason you may want to change the default model is if you want authentication to behave differently from the default behavior. Perhaps you want to support a phone number for communication purposes, or even use it as a unique identifier for the user. We want our custom user to look very similar to the default Django User, but instead of a username field, we want the email field to be the unique identifier.

When you override the User model, there are a number of steps you have to take to make sure the interface is what Django expects, so that all the provided Django features still work. To help with this, Django provides an AbstractBaseUser class and a BaseUserManager class that help provide some default behaviors and interfaces that Django expects to be present.

This tells Django and any third party applications where to find the model we need to use for authentication. Now that we have our custom User model defined and registered with Django, we can generate the migrations required to create the database table s for our new structure:.

Now, we want to see our User model in action. The easiest way for us to do so within our application is to see what it looks like in the Django admin. Before we can see our model in action, we need to get the database setup. We do this by applying the migrations we created previously:. To gain access to the Django Admin site, we need to create a user with admin access.

The simplest way of doing this is to create a superuser through the command line client:. Once the command has been completed, the user has been created! Using the email address and password provided to the createsuperuser command lets you log in to the admin site. This tells Django to create an admin page for the model with default settings.I'm a passionate software developer and researcher from Brazil, currently living in Finland.

I write about Python, Django and Web Development on a weekly basis. Read more. For the most part we can use it out-of-the-box, saving a lot of development and testing effort.

It fits most of the use cases and is very safe. But sometimes we need to do some fine adjustment so to fit our Web application. Commonly we want to store a few more data related to our User. If your Web application have an social appeal, you might want to store a short bio, the location of the user, and other things like that.

Generally speaking, there are four different ways to extend the existing User model. Read below why and when to use them. What is a Proxy Model? It is a model inheritance without creating a new table in the database. It is used to change the behaviour of an existing model e.

When should I use a Proxy Model? What is a One-To-One Link?

We usually call it a User Profile. It is an entirely new User model that inherit from AbstractBaseUser. It requires a special care and to update some references through the settings. Ideally it should be done in the begining of the project, since it will dramatically impact the database schema. Extra care while implementing it. You should use a Custom User Model when your application have specific requirements in relation to the authentication process.

For example, in some cases it makes more sense to use an email address as your identification token instead of a username. It is a new User model that inherit from AbstractUser. Yet, you want to add some extra information directly in the User model, without having to create an extra class like in the Option 2.

This is the less intrusive way to extend the existing User model. But it is very limited in many ways. In the example above we have defined a Proxy Model named Person. It is worth noting that User. The only difference is in the behavior we define for the Proxy Model. There is a good chance that this is what you want.

Personally that is the method I use for the most part. We will be creating a new Django Model to store the extra information that relates to the User Model. Bear in mind that using this strategy results in additional queries or joins to retrieve the related data. Basically all the time you access an related data, Django will fire an additional query.

But this can be avoided for the most cases. I will get back to that later on. Everything is done through the User model. Oh, right.GitHub is home to over 50 million developers working together to host and review code, manage projects, and build software together. Work fast with our official CLI.

The reason is if you want to make any changes to the User model down the road--for example adding a date of birth field--using a custom user model from the beginning makes this quite easy. But if you do not, updating the default User model in an existing Django project is very, very challenging.

So always use a custom user model for all new Django projects. However the official documentation example is not actually what many Django experts recommend using.

There is a far easier yet still powerful approach to starting off new Django projects with a custom user model which I'll demonstrate here. If you're brand new to user authentication in Django, I recommend first reviewing how to implement a regular login, logout, signup flow in Django which covers the basics in detail.

Note that we did not run migrate to configure our database. It's important to wait until after we've created our new custom user model before doing so. In both cases we can subclass them to extend existing functionality however AbstractBaseUser requires much, much more work.

Seriously, don't mess with it unless you really know what you're doing. And if you did, you wouldn't be reading this tutorial, would you? So we'll use AbstractUser which actually subclasses AbstractBaseUser but provides more default configuration.

In settings. We'll call our custom user model CustomUser. We need new versions of two form methods that receive heavy use working with users. Finally we update admin. And we're done! We can now run makemigrations and migrate for the first time to create a new database that uses the custom user model. On the command line type the following command and go through the prompts.

Our goal is a homepage with links to log in, log out, and sign up. Start by updating settings. Then set the redirect links for log in and log out, which will both go to our home template. Add these two lines at the bottom of the file. Create a new project-level templates folder and within it a registration folder as that's where Django will look for the log in template.

We will also put our signup. Last step is our views. Start up the server with python manage. Upon successful submission you'll be redirected back to the homepage and see a personalized greeting. Create a new user. Mine is called testuser. After successfully submitting the form you'll be redirected to the login page. Log in with your new user and you'll again be redirected to the homepage with a personalized greeting for the new user.
