Set context depending on many2many ids to domain or filter other many2many.

In model

batch_id = fields.Many2one('ae.batch', 'Batch')
subject_ids = fields.Many2many('ae.subject', string="Subjects")
topic_ids = fields.Many2many('ae.topic', string="Topics")
subtopic_ids = fields.Many2many('ae.subtopic', string="Subtopics")

The goal is to pass context in order to filter(domain), picking a Batch filters Subjects, choose Subjects, could be one or more, to filter Topics, and filter Subtopics.

Check view:

<group col="4" name="plan_detail" String='Choose t'>
<field name="batch_id" 
    context="{'batch_id':batch_id}"/>

<field name="subject_ids" 
    domain="[('batch_id', '=', batch_id)]" 
    context="{'subject_ids': subject_ids}"/>

<field name="topic_ids" 
    domain="[('subject_id', 'in', 'subject_ids')]"
    context="{'topic_ids': topic_ids}" />

<field name="subtopic_ids" widget="many2many_checkboxes" 
    domain="[('topic_id', 'in', topic_ids)]" />

What is working, picking the Batch filters correctly all Subjects. Stucked between Subjects to Topics, I think is a context or domain problem, I've tested changing the domain manually like so:

<field name="topic_ids" 
    domain="[('subject_id', 'in', '[1, 2]')]"
    context="{'topic_ids': topic_ids}" />

And successfully gets Topic list. I guess I am wrong passing context or getting domain.

Hi, 

Is the current scenario like ,you need to filter subjects based on batches and topics based on the subjects and sub topics based on topics plus subjects ,topics and sub topics are manytomany fields. If yes then i hope passing domain  via .py file could solve your issue.i have provided an example below.Hope this could help you :)


@api.onchange('subject_ids')
def onchange_subject_ids(self):
listids=[]
if self.subject_ids:
for each in self.subject_ids:
listids.append(each.id)
domain = {
'topic_ids': [('id', 'in', listids)]}
return {'domain': domain, 'value': {'topic_ids': []}}

I just found another way to achieve this, very simple actually.

Since the context for many2many-one2many is a recordset (little changes in bold):

<field name="batch_id" 
    context="{'batch_id': 'batch_id'}"/>

<field name="subject_ids" 
    domain="[('batch_id', '=', batch_id)]" 
    context="{'subject_ids': 'subject_ids'}"/>

<field name="topic_ids" 
    domain="[('subject_id', 'in', subject_ids[0][2])]"
    context="{'topic_ids': 'topic_ids'}" />

<field name="subtopic_ids" widget="many2many_checkboxes" 
    domain="[('topic_id', 'in', topic_ids[0][2])]" />
