I have a Many2One field - 'follow_up" in a model named “cushing_syndrome”. I want to display this field as a form in the cushing_syndrome model.
Is there any way to display this without migrating the follow_up fields in cushing_syndrom
No really. The Many2One API does not allow to show it as a form.
But there are two options to keep the same database schema and still display information:
Add Function fields that show data from the target of the Many2One and display them on the form. You can use
gettersuch that the value will be updated when the Many2One is changed.
Add a One2Many Function field that contains just the target of the Many2One. Set a size limit to 1 and display the One2Many as form. Again the
gettercould also be a
on_change_with. If you want to support edition of this form, you will have to define a
setterbut be careful that the API of One2Many can be complex to support.
