conditions for a field to appear in odoo 14

I'd like field A to appear only if field B has a given value

field B doesn't belong to the same model, it belongs to a model connected through a many2one relationship

How do I write the contents of the attrs attribute for field A in the form ?

Until now I used

<field name="A"...
attrs="{'invisible': [('B', '=', 'some_value')

But until now both A and B belonged to the same model

Field used in attrs must be present in view

You can't use dotted field names because Odoo will raise an error if the field name contain . when validating the view definition:

Invalid composed field %(definition)s in %(use)s (attrs.invisible ...)

There is an exception for list sub-views (One2many/Many2many display in a form view) where you can use parent.field_name

ok, I reply to myself

First, in the model:

field_B = field.fieldtype(related='many2one_field.field_b')

Then, in the form view:

<field name="field_B" invisible="1"/>

and then

<field name="field_A" ...
        attrs="{'invisible': [('field_B', '=', 'some_value')]}">
