Hello,

I would like to ask for an advice about many2one fields please.

I created a model called 'mymodel' which is connected to 'project.issue' like this:

class project_issue_mymodel(models.Model):
   _inherit = 'project.issue'
   mymodel_id = fields.Many2one('mymodel',string='mymodel data', ondelete='cascade')

When I want to use 'mymodel_id' field in a view it works just fine when I add this into the xml file:

<field name="mymodel_id" />

Then 'name' of that record is displayed there.

But when I want to customize this further and display some more fields from the connected 'mymodel' record nothing more is displayed there. Basically everything inside <field name="mymodel_id">...</field> is ignored.I haven't found any way to display fields from my connected 'mymodel' record. This is my source code:

#mymodel.py file

class mymodel(models.Model):
    _name = 'mymodel'
    testfield1 = fields.Char()
    testfield2 = fields.Char()

#project.issue view

<field name="mymodel_id">
	<form>
		<field name="id" />
		<field name="testfield1" />
		<field name="testfield2" />
	</form>
</field>

Would you please give me some advice about this? Is this even possible?
