Odoo Module Interaction

Goal

Extend functionality by leveraging other installed modules (e.g., creating an Invoice from the Real Estate module).

1. Link Modules

A "Link Module" is a module designed to glue two other independent modules together.

• Dependencies: In __manifest__.py, depend on both modules.

  'depends': ['estate', 'account'],
  

• Purpose: Keeps the original modules decoupled. estate doesn't need to know about account, and vice-versa.

2. Cross-Module Model Inheritance

To extend logic from another module, inherit the model and override methods.

Example: Trigger Invoice Creation on Property Sale

class EstateProperty(models.Model):
    _inherit = "estate.property"

    def action_sold(self):
        # 1. Call super to execute original logic (set state to sold)
        res = super().action_sold()
        
        # 2. Add new logic (Create Invoice)
        for prop in self:
            self.env["account.move"].create({
                "partner_id": prop.buyer_id.id,
                "move_type": "out_invoice",
                "line_ids": [
                    Command.create({
                        "name": prop.name,
                        "quantity": 1,
                        "price_unit": prop.selling_price * 0.06,
                    }),
                    Command.create({
                        "name": "Administrative Fees",
                        "quantity": 1,
                        "price_unit": 100.00,
                    }),
                ],
            })
        return res

3. Creating Records Programmatically

Use self.env['model.name'].create(values_dict).

• Values Dict: Keys are field names, values are the data.
• Relational Fields:
  • Many2one: Pass the integer ID (e.g., 'partner_id': 5).
  • One2many/Many2many: Use Command tuples (e.g., [Command.create({...})]).

4. Debugging Tips

• Always check if the module is installed.
• Use print() or a debugger to verify method overrides are triggering.
• Ensure users have access rights to the models you are interacting with.
