Feeding search results to a domain criteria

[Khurram Shahzad]

Dear All,

I have defined a domain for a filed as follows:

blood_bags = fields.Many2Many('anth.request-bag', 'blood_request', 'blood_bag', 'Blood Bags', required=True, domain=[('state','=','cross_matched'), ('id', 'in', [1,2])])

Consider condition ('id', 'in', [1,2]) where I have hard-coded values 1 & 2. Is there a way that I can search a model and use the returned list here dynamically.

If those records have been created using XML data then you can use the
pyson.Id [1]. Otherwise you have to find a way to express the domain
using dot notation.

If the domain is applied on the field, you should use a One2Many
function field (which will do the compute and return the ids), and use
the following domain:

[('state', '=', 'cross_matched'), ('id', 'in',

Eval('your_function_field', [])]

Having said taht, I'm wondering why you want to use the ids, if you are
going to use a search clause on target model. You can use the '.' to
perform joins domain clauses. For example: Using 'direct_field.name'
will search on the name fields of the records related by the
'direct_field' field. Of course, the direct field must be a relation one.

Hope it helps.

Dear Cedric & Sergi,

Thanks for your responses.

These records have not been created using xml file.

The method by Sergi didn't work as well.

Infact, I want to search records on the basis of 'origin' model as well as 'target' model. Simply, I want to return those 'blood_bag' model objects whose 'state' is 'cross_matched' AND they have been cross-matched against 'blood_request'. The blood_request model is related to blood_bag.

Regards,

Khurram.

Without having the database schema/models, it is not possible to help
you.
