Hello,

I'm using Odoo 13 Community Edition.

In my case I need a routing for every product.

So to assign every routing to a product I created this field in my custom module for product.template:

class ProductTemplate(models.Model):

    _inherit = ['product.template']

    routing_id = fields.Many2one(

        'mrp.routing', 'Arbeitsplan', compute='_compute_routing_id')

    @api.depends('routing_id')

    def _compute_routing_id(self):

        for product in self:

            product.routing_id = self.env['mrp.routing'].search([('product_id','=',product.id)])

And in mrp.routing:

class MrpRouting(models.Model):

    _inherit = ['mrp.routing']

    product_id = fields.Many2one(

        'product.template', 'Produkt', required=True)

    @api.onchange('product_id')    

    def _onchange_product_id_name(self):

        self.name = self.product_id.name

(The onchange method because I made the name field invisible in the form view.)

Now I thought I could show the operation_ids field directly in the product.template form view.

So I also added the field to product.template in my custom module like the routing_id:

class ProductTemplate(models.Model):

    _inherit = ['product.template']

    operation_ids = fields.One2many(

        'mrp.routing.workcenter', 'routing_id', 'Operations',

        copy=True)

And in the form view:

        <record id="product_template_only_form_view_mgtec" model="ir.ui.view">

            <field name="name">product.template.product.form.mgtec</field>

            <field name="model">product.template</field>

            <field name="inherit_id" ref="product.product_template_only_form_view"/>

<field name="priority" eval="100"/>

            <field name="arch" type="xml">

<xpath expr="//page[@name='variants']" position="before">

<page string="Vorgänge" name="vorgaenge">

                        <field name="operation_ids" context="{'default_routing_id': routing_id}"/>

</page>

</xpath>

</field>

</record>

But when I want to change the operations in the product view and it opens the pop up form view from mrp.routing.workcenter to change the operations in the routing, I get an error and its like a never ending story like it needs every field from product.template/product.product in mrp.routing.

I searched for a method that could cause the errors, but i dont find any solution.

Thanks in advance.

The full error code:
