Creating models

For the To-Do tasks to have a kanban board, we need stages. Stages are board columns, and each task will fit into one of these columns:

1. Edit todo_stage/__init__.py to import the models submodule:

from . import models 

2. Create the todo_stage/models directory and add to it an __init__.py file with this:

from . import todo_task_tag_model
from . import todo_task_stage_model

3. Add the todo_stage/models/todo_task_tag_model.py Python code file:

from odoo import fields, models

class Tag(models.Model):
    _name = 'todo.task.tag'
    _description = 'To-do Tag'
    name = fields.Char('Name', translate=True) 

4. Then, add the todo_stage/models/todo_task_stage_model.py Python code file:

from odoo import fields, models

class Stage(models.Model):
    _name = 'todo.task.stage'
    _description = 'To-do Stage'
    _order = 'sequence,name'

    name = fields.Char('Name', translate=True)
    sequence = fields.Integer('Sequence') 

Here, we created the two new models that will be referenced in the To-Do tasks.

Focusing on the task stages, we have a Python class, Stage, based on the models.Model class, which defines a new Odoo model called todo.task.stage. We also have two fields: name and sequence. We can see some model attributes (prefixed with an underscore) that are new to us. Let's have a closer look at them.
