How to Implement a 3 way relationship in odoo

Question

I have 3 models. Module 1 has a One2many relationship with module 2. Module 2 has One2many relationship with Module 3. I am trying to use a View Created for Module 1 to enter data into all the Three modules. The code is provided below. of the models and the views. When I try to add data into Module 3. I am getting the following error.

Traceback (most recent call last):
  File "C:\Apps\hrms\odoo\models.py", line 5322, in _update_cache
    field_values = [(fields[name], value) for name, value in values.items()]
  File "C:\Apps\hrms\odoo\models.py", line 5322, in <listcomp>
    field_values = [(fields[name], value) for name, value in values.items()]
KeyError: 'name'

During handling of the above exception, another exception occurred:

    raise ValueError("Invalid field %r on model %r" % (e.args[0], self._name))
ValueError: Invalid field 'name' on model 'zm.strategic.plans'

The above server error caused the following client error:
null

It is saying that the field is invalid on the model..

Below is the code for the models...

from odoo import api, fields, models


class StrategicPlans(models.Model):
    _name = "zm.strategic.plans"
    _description = "National Strategic Plans"
    _rec_name = "doc_title"

    doc_title = fields.Char(string="Title", required="true")
    level = fields.Selection([
        ('1', 'National'),
        ('2', 'Ministerial')
    ])
    ministry = fields.Char(string="Ministry")
    period = fields.Char(string="Plan Year")
    objective_ids = fields.One2many('zm.strategic.objective', 'objective_id', string='Strategic Objectives',
                                    copy=True, auto_join=True, ondelete='cascade')


class Objective(models.Model):
    _name = 'zm.strategic.objective'
    _description = 'Strategy'

    name = fields.Char(string='Objective', required=True)
    objective_id = fields.Many2one('zm.strategic.plans', string='Objective', required=True,
                                   index=True, copy=False)
    objective = fields.Char(string="Strategic Objectives", required="true")
    strategy_obj_ids = fields.One2many('zm.strategic.strategy', 'strategy_id', string='Strategies',
                                       copy=True, auto_join=True)


class Strategy(models.Model):
    _name = 'zm.strategic.strategy'
    _description = 'Strategy'

    name = fields.Char(string='Strategy', required=True)
    strategy_id = fields.Many2one('zm.strategic.plans', string='Objective', required=True,
                                  index=True, copy=False)

Below is the code for the view that is suppose to handle all of this..

</odoo>
    <record id="view_strategic_plan_form" model="ir.ui.view">
        <field name="name">zm.strategic.plans.form</field>

                    </notebook>
                </sheet>
            </form>
        </field>
    </record>

    <!--The core code that contains the action-->
    <record id="action_strategic_plan" model="ir.actions.act_window">
        <field name="name">Strategic Plans</field>
        <field name="type">ir.actions.act_window</field>
        <field name="res_model">zm.strategic.plans</field>
        <field name="view_mode">tree,form,kanban,pivot</field>
        <field name="help" type="html">
            <p class="o_view_nocontent_smiling_face">
            </p>
        </field>
    </record>
</odoo>

I tried defining the context in which to access the fields. I am able to see the field and the name but I cannot add information through that field. I used the code below

context="{'default_strategic_objective_id': active_id}" mode="tree,form"
