Hi, I'm using odoo 14 and here is my situation:

class User(Model):
_name = "user"
name = fields.Char()

class Project(Model):
_name = "project"
name = fields.Char()

class Task(Model):
_name = "task"
name = fields.Char()
user_id = fields.Many2one("user")
project_id = fields.Many2one("project")

Both User and Project have the inverse fields to Task.

Is it possible to put a Project tree view with all the records in the User form view? I would like to create a new Task from the User form view and clicking on the Project record to which the task is to be assigned I would like a Task form view to appear with the Task user_id and project_id fields already set according to the context.
