I have created one custom model that contain three relation fields. Following is relations: 

class SurveyCreate(models.Model):

    _name = 'create.survey’

    survey_name = fields.Many2one('survey.survey',string='Survey Title')
    pages_id = fields.One2many('survey.page','create_id_survey','Pages')
    questions_survey = fields.One2many('survey.question','create_id_survey','Questions')

and many2one fields created in survey.page & survey.question resp.

Follwing is xml file:


<group>
                    <field name="survey_name"/>
                </group>
                <group>
                    <field name="pages_id" mode="tree">
                        <tree editable="bottom">
                            <control>
                                <create string="Add page"/>
                            </control>
                            <field name="title"/>   
                            <field name="questions_id" widget="many2many_tags" options="{'no_create':True}" context="{'tree_view_ref':'survey_inherit.questions_survey'}"/> 
                        </tree>
                    </field>
                </group>
                <group> 
                    <field name="questions_survey" mode='tree'>
                        <control>
                            <create string="Add Question"/>
                        </control>
                        <tree name="questions_tree" editable="bottom">
                            <field name="question"/>
                            <field name="type"/>
                        </tree>                 
                    </field>
                </group>

  • Do you try to display the `question` field in `Questions` tags? – Kenly Dec 15 '19 at 08:51
  • Yes with help of @api.onchange. ```@api.onchange('pages_id') def page_onchange_question(self): print('In on change') self.questions_survey = self.env['survey.question'].search([('question','=','questions_id.question')]) print('self.questions_survey',self.questions_survey)```but question not display in Questions tag – sss Dec 16 '19 at 07:04

To get the same display as account.tax you will need a name field which is used to display records in x2many fields.

If you want to keep question field and used it to display questions in questions_survey, you have to use _rec_name in survey.question model. 

class SurveyQuestion(models.Model):
    _name = 'survey.question'
    _description = ''
    _rec_name = 'question'

Or you can override name_get method to display a custom value.
