 ODOO 

In this case we have many2one field for model that has more than one view and we want to open specific view from this field for this model

let us give an example :

- we have model "object.a" and model "object.b", in which we have object_a_id field as bellow 

object_a_id = fields.Many2one('object.a', string="Object A")

 

- model "object.a" has two form view with ids "object_a_form_view_1" and "object_a_form_view_2" and "object_a_form_view_1" id the default view and we want to show the other view from object_a_id field , so we can do it by add the field in the xml file as bellow

 

<field name="object_a_id" context="{'form_view_ref':'module_name.object_a_form_view_2',}" />

The tag is deprecated, use a tag for

 ODOO 

odoo 14

 

"The <report> tag is deprecated, use a <record> tag for ...etc "

some time you can get the error above when you create new report tin odoo 14.0 because 90% created it as bellow ,

<report
            id="report_action_id"
            string="Report Name"
            model="model.name"
            report_type="qweb-html"
            name="module_name.report_temp_id"
            menu="True"
        />

But , You have to create it as bellow to fix this error 

 

<record id="report_action_id" model="ir.actions.report">
        <field name="name">Report Name</field>
        <field name="model">model.name</field>
        <field name="report_type">qweb-pdf</field>
        <field name="report_name">module_name.report_temp_id</field>
        <field name="report_file">module_name.report_temp_id</field>
        <field name="binding_model_id" ref="model.name"/>
        <field name="binding_type">report</field>

</record>

many2one field domain from function

 ODOO

 odoo 14

 

in this blog we will explain how we can define domain for Many2one field in odoo 14 , so let us start 

 

First we have "object.a" model which is contain Many2many in which we will add many users , as bellow

user_ids = fields.Many2many('res.users', string="Users")

Second we have "object.b" model , which we have user_id field that contain the current user , and object_a_id which is Many2one field from object "A" , as bellow

user_id = fields.Many2one('res.users', string='Created By', default=lambda self: self.env.user, readonly=True)

object_a_id = fields.Many2one('object.a', string="A")

and we need to make domain over object_a_id field to show only the records from object A that the current user is involved in the user_ids field 

....

To make the domain we have to add function as bellow  

    @api.onchange('some_field_in_B_object')
    def _get_object_b_ids(self):
        """
        function to get the A records for the current user
        """
        object_a_ids = self.env['object.a'].search([])
        ids_lis = []
        domain = [('id','=', -1)]

        for rec in object_a_ids:
            for line in rec.user_ids:
                if self.user_id == line:
                    ids_lis.append(rec.id)
        res = {}
        res['domain'] = {'object_a_id': [('id', 'in', ids_lis)]}
        return res

How to use many2one field in demo data

Odoo

Demo Data

 

 

 In this blog we will explain how to add value for many2one field in the xml demo data file in odoo , so let us start 

First let us say we have python object by the name 'report.create' which is contain the model_id field which is many2one field from 'ir.model' as bellow 

class ReportCreater(models.Model):
    _name = 'report.creater'

    model_id = fields.Many2one(
        'ir.model', string='Model', required=True, ondelete="cascade",
        help="The type of document this template can be used with")

and we want to create demo data for this object and the records from the demo data must contain the model_id field , so we can do it as bellow 

<odoo>
  <data noupdate="0">
    <record id="simple_contract_template" model="desined.report.template">
      <field model="ir.model" name="model_id" search="[('model', '=', 'res.partner')]"/>
    </record>
  </data>
</odoo>

 

*NOTES

• 'ir.model' this object contain all models in the data base
• search="[('model', '=', 'res.partner')] in this step we made search in the 'ir.model' object to return record from it , and in that record the value of model field must be 'res.partner'
• 'ir.model' contain the model field which is char field
