Sometimes I found ('','','') expression for domain or ['','',''].

I want to know : Where do I use () or [] for write domain expression?

The two datatype are equal in this case. If you create a filter you can use tuple or list. The standard is to set the filters as list of tuple. This is an example:

filter = [('name', 'ilike', 'OpenERP'), ('type', '=', 'erp')]

I can use list or tuple in .xml file AND in UI form ?

You can use tuple and list in every point of the software. This type of data are part of python.

Hello Denis,

Domain is a python code for optional restriction in the form of arguments for search.


domain =  [['field_name', 'operator', 'value'], ...]

For example,

domain = [('state','<>','draft'), ('country_id', '=', country_id)]

Thank you.
