Odoo/OpenERP: Custom unique name constraint with ignore case

#custom unique name constraint with ignore case

def _check_unique_insesitive(self, cr, uid, ids, context=None):

        list_ids = self.search(cr, uid , [], context=context)

        lst = [list_id.name.lower() for list_id in self.browse(cr, uid, list_ids, context=context) if list_id.name and list_id.id not in ids]

        for self_obj in self.browse(cr, uid, ids, context=context):
            if self_obj.name and self_obj.name.lower() in lst:
                return False
            return True


Use as following in your class :

_constraints = [(_check_unique_insesitive, <error_message>, ['<field_name>'])] 

e.g : _constraints = [(_check_unique_insesitive, 'Name already exists', ['name'])]

Odoo: Qweb Templates Cache Issue

Hi Everyone, Today I was working on a hotel booking template in Odoo and changes made in the Qweb template(.xml) were not reflecting on updating module with odoo service restart. Tried few times without any success :(. Finally, I decided to delete the old template from Odoo backend and then update module again and it worked like a charm!! :) Steps to delete template from backend: Settings --> User Interface --> Views --> Search by template name Delete the used template. Although it's a small post, but I'm sure it will meet the purpose and help someone in the future. Thanks!!! Enjoy Programming!! :) Reference Links: =================================== https://www.odoo.com/forum/help-1/question/odoo-cache-and-updating-qweb-templates-84492

Odoo/OpenERP: one2one relational field example

one2one relational field is deprecated in OpenERP version>5 but you can achieve the same using many2one relational field. You can achieve it in following two ways : 1) using many2one field in both the objects ( http://tutorialopenerp.wordpress.com/2014/04/23/one2one/ ) 2)  using inheritance by deligation You can easily find the first solution with little search over internet so let's start with 2nd solution.
