domain rule for selecting certain records

[Khurram Shahzad]

Hi All,

I have a 'AdmiittedPatient' class with following two fields:

patient = fields.One2Many('party.party','Patient')
bed_transfers = fields.One2Many('gnuhealth.bed.transfer', 'name',
        'Transfer History', readonly=True)

where  gnuhealth.bed.transfer ('BedTransfers') class has:
    bed_from = fields.Many2One('gnuhealth.hospital.bed', 'From',)
    bed_to = fields.Many2One('gnuhealth.hospital.bed', 'To',)

Now, I am trying to write a domain rule which will display those patients who were transferred to a Bed with id 15.

(Eval('15'), 'in', [Eval('bed_transfers',{}).get('bed_from', -1)])

But, it is failing with an error. Any help please?

What are you calling a "domain rule"?

Eval('15') can never work. If you want the number 15, you must type: 15

What are you calling a "domain rule"?

Sorry, I was referring to "domain clause", I was writing in my module's view.xml file.

Eval('15') can never work. If you want the number 15, you must type: 15

Changing it to 15 didn't work either. In fact, 'bed_transfers' is a one2Many field. What I want is to get list  values of 'bed_from' field from every record of this one2Many field. I think, the above-given code will consider 'bed_tranfers' a dictionary and return value of 'bed_from' it.

I do not see where you try to put this domain. Is it a
ir.action.act_window.domain ?

The result of the evaluation of a One2Many is a list of id. You can not
retrieve a specific field from the list.
You need to create a Function field that provide you the right data at
the main record.

Yes, it is!

Ok. I will create a function field. Thanks for the clue.
