Hi, I have defined these classes:
class brand(osv.osv):
_name = "cm.brand"
_columns = {
'name': fields.char('Marca', size=30)
}
class model(osv.osv):
_name = "cm.model"
_columns = {
'name': fields.char('Modelo', size=30)
}
class cm_application_data_line(osv.osv):
_name = "cm.application.data.line"
_columns = {
'comun_denominador_id': fields.many2one('comun.denominador', 'Comun denominador', required=True, ondelete='cascade'),
'brand': fields.many2one('cm.brand', 'Marca', required=True, ondelete='restrict'),
'date_beg': fields.selection([(num, str(num)) for num in range(1980, (datetime.now().year)+1 )], 'Año inicial'),
'dateend': fields.selection([(num, str(num)) for num in range(1980, (datetime.now().year)+1 )], 'Año final'),
'model': fields.many2one('cm.model', 'Modelo', required=True, ondelete='restrict')
}
I did this to get a page view on my 'comun.denominador' new model:
class comun_denominador(osv.osv):
_name='comun.denominador'
_rec_name='comun_denominador'
_columns = {
'comun_denominador': fields.char('Común denominador', size=10),
'application_data_comun_denominador_ids': fields.one2many('cm.application.data.line', 'comun_denominador_id', 'Datos de aplicación del común denominador')
}
And xml view:
<notebook>
<page string="Datos de aplicación">
<field name="application_data_comun_denominador_ids" widget="one2many_list" context="{'show_attribute': False}">
<tree string="Aplicación" editable="bottom">
<field name="brand" />
<field name="model" />
<field name="date_beg"/>
<field name="dateend"/>
</tree>
</field>
</page>
</notebook>
So far, everything is fine. Now, in product.template form view I added exactly the same page in form view and added a field 'cm_id' making reference to 'comun.denominador' model, so that when users chooses 'cm_id', on_change method brings all values from page in 'comun.denominador' to my new page in 'product.template':
XML sample in product.template:
<xpath expr="//field[@name='sale_ok']" position="after">
<separator colspan="2" string="Común denominador"/>
<field name="cm_id" on_change="on_change_cm_id(cm_id)"/>
</xpath>
<xpath expr="//page[@string='Sales']" position="after">
<page string="Datos de aplicación">
<field name="application_data_product_template_ids" widget="one2many_list" context="{'show_attribute': False}">
<tree string="Aplicación" editable="bottom">
<field name="brand" />
<field name="model" />
<field name="date_beg"/>
<field name="dateend"/>
</tree>
</field>
</page>
</xpath>
New class and product.template inheritance:
class product_template_application_data_line(osv.osv):
_name = "product.template.application.data.line"
_rec_name = 'brand'
_columns = {
'product_template_id': fields.many2one('product.template', 'Product template', required=True, ondelete='cascade'),
'brand': fields.many2one('cm.brand', 'Marca', required=True, ondelete='restrict'),
'date_beg': fields.selection([(num, str(num)) for num in range(1980, (datetime.now().year)+1 )], 'Año inicial'),
'dateend': fields.selection([(num, str(num)) for num in range(1980, (datetime.now().year)+1 )], 'Año final'),
'model': fields.many2one('cm.model', 'Modelo', required=True, ondelete='restrict')
}
class comun_denominador_product_template(osv.osv):
_inherit = 'product.template'
_name='product.template'
def on_change_cm_id(self,cr, uid, ids,cm_id,context=None):
context=context or {}
application_data_product_template = []
dict = {}
if ids:
application_ids = self.pool.get('product.template.application.data.line').search(cr, uid,[('product_template_id','in',ids)])
self.pool.get('product.template.application.data.line').unlink(cr, uid, application_ids)
application_cm_ids = []
application_cm_ids = self.pool.get('cm.application.data.line').search(cr, uid, [('comun_denominador_id', '=', cm_id)])
for application_id in self.pool.get('cm.application.data.line').read(cr, uid, application_cm_ids, ['brand', 'date_beg', 'dateend', 'model']):
application_data_product_template.append((0,0,{'brand':application_id['brand'][0],'date_beg':application_id['date_beg'], 'dateend':application_id['dateend'], 'model':application_id['model'][0]}))
dict.update(application_data_product_template_ids=application_data_product_template)
return {'dict':dict}
_columns = {
'cm_id' : fields.many2one('comun.denominador','Común denominador', select=True, ondelete='cascade'),
'application_data_product_template_ids': fields.one2many('product.template.application.data.line', 'product_template_id', 'Datos de aplicación de la tabla de producto')
}
When I select cm_id, I see no error log, what is more, setting up debugger my on_change function returns a dict like this:
dict: {'application_data_product_template_ids': [(0, 0, {'brand': 2, 'date_beg': 1995, 'dateend': 2009, 'model': 5}), (0, 0, {'brand': 1, 'date_beg': 1995, 'dateend': 2006, 'model': 2})]}
However, my page values on product.template don't get uploaded.
Please, some suggestions!!
