A user with that username already exists, when create a new project

My actions before raising this issue

• Read/searched the docs

Allow: GET, POST, HEAD

Vary: Accept

{
    "owner": {
        "username": [
            "A user with that username already exists."
        ]
    },
    "assignee": {
        "username": [
            "A user with that username already exists."
        ]
    }
}

Expected Behaviour

A project should be created, owned by the provided owner and assigned to the provided assignee.

I am runing the `python manage.py runserver `, and using the REST API `create` to create a new project. the `owner` and `assignee` name are required. and I assign the exists username info, the validation error is : "A user with that username already exists.", but i assign the no exists username, i meet other error: Cannot assign "OrderedDict([('username', 'xxx'), ('first_name', ''), ('last_name', '')])": "Project.assignee" must be a "User" instance. ### Current Behaviour

Possible Solution

Steps to Reproduce (for bugs)

1. git clone repo.
   2.install requirement python env.
2. run python manage.py runserver
3. http://localhost:8080/api/v1/projects

{
    "name": "test",
    "labels": [],
    "owner": {
        "username": "testuser",
        "first_name": "",
        "last_name": ""
    },
    "assignee": {
        "username": "testuser",
        "first_name": "",
        "last_name": ""
    },
    "owner_id": null,
    "assignee_id": null,
    "bug_tracker": "",
    "task_subsets": [],
    "training_project": {
        "host": "test",
        "username": "testuser",
        "password": "testuser",
        "enabled": false,
        "project_class": null
    },
    "dimension": "2D"
}

Hi @CvHadesSun

Try to omit assignee and owner fields, setting owner_id and assignee_id in POST and PATCH requests.

[CvHadesSun]

Yes, I want to omit two fields, but I set the owner and assignee blank, and get the error:

    "owner": {
        "username": [
            "This field may not be blank."
        ]
    },
    "assignee": {
        "username": [
            "This field may not be blank."
        ]
    }

How should I do to omit two fields and create a new project?

[bsekachev]

I referred to UI to see what requests it sends to the server:

POST:

PATCH:

Try to do the things your are doing this way in two requests.
Owner field is set automatically (owner is a user who sent the POST request), you probably can't set it via API.

[CvHadesSun]

ok, I understand. Thanks for your reply.
