Hi @MartaLeal, in this case, you need to change the display name in your model, probably for this reason the field is displaying the ID instead of name.

Use something like this in your doctor model:

class ResDoctoc(models.Model):
	​_inherit = 'res.doctor'
	​_res_name = 'doc_name' # here you put your model name.

	​doc_name = fields.Char()

I hope it helps someone!

Hello both!

None of them worked. It still displays the id (I suppose it is the key of the relationship). I'm not sure if I had not explained it clearly. Going back to the example, where I want to see the name of the doctor is in the tree view of the menu, not inside the model. I need to see it at a first glance, not by entering to the record and then checking who is the doctor.

What I need is this:

if you want to see only name you can use <field name="field_name" widget="many2many_tags"/>

if you want to show other detail then use bellow

<field name="field_name" nolabel="1">

                                    <tree editable="bottom">

                                        <field name="name"/>

                                        <field name="email"/>
                                        <field name="number"/>

                                    </tree>

                                </field>
