Hello to all , I have been trying to use a drop down menu list in my openerp module. I have a many2one field containing categories . This field is associated with an onchange function. This onchange function is returning new values to 2nd field. Now everything is working ok but I want to use a dropdown type menu in the 2nd field so that I can select the values from it. My Python code is as follows:

class deg_form(osv.osv):

    _name = "deg.form"
    _columns = {
         'categ1':fields.many2one('product.category','Parent Category',required=True),
         'my_products':fields.char('Product',size=64)

            }

    def Product_Category_OnChange(self,cr,uid,ids,categ1):
            pro_id=[]
            cr.execute('select id,name from product_template where  categ_id in (select id from product_category where parent_id in (select id from product_category where parent_id='+str(categ1)+'))  union select id,name from product_template where  categ_id in (select id from product_category where parent_id='+str(categ1)+') union select id,name from product_template where categ_id='+str(categ1))


    res = cr.fetchall()
    for pid,name in res:
            pro_id.append((pid,name))
        return {'value':{'my_products':pro_id}}

here is my xml code:

 <field name="categ1" on_change="Product_Category_OnChange(categ1)" />

Please help me to achieve this. Thanks n Regards

You don't need to write on change method just remove that method and try below code.

in Python file:

'categ1':fields.many2one('product.category','Parent Category',required=True),
'my_products':fields.many2one('product.product','Product')

and in XML file:

<field name="categ1" on_change="Product_Category_OnChange(categ1)" />
<field name="my_products" domain="[('categ_id','=',categ1)]"/>

Hi,

Try this code '

my_products':fields.many2one('product.product','Product')

def Product_Category_OnChange(self,cr,uid,ids,categ1):
        pro_id=[]
        cr.execute('select id from product_template where  categ_id in (select id from product_category where parent_id in (select id from product_category where parent_id='+str(categ1)+'))  union select id,name from product_template where  categ_id in (select id from product_category where parent_id='+str(categ1)+') union select id,name from product_template where categ_id='+str(categ1))


    res = cr.fetchall()
    for pid in res:
            pro_id.append(pid)
    return {'value':{'my_products':pro_id}}

On doing this , I m having error : TypeError: Object [object Array] has no method 'split'

Jagdish Panchal 
for pid,name in res:
        pro_id.append(pid)  use this code in your onchange function.

Now its giving me this -> TypeError: Object 29 has no method 'split'

Jagdish Panchal

have you upgrade your module ??if not then upgrade module and try this

arsalan
Avtor

yes I upgraded , but no change

Jagdish Panchal

I have update ans pls check it.

arsalan
Avtor

yes I tried but getting TypeError: Object 29 has no method 'split'

Jagdish Panchal

Hi return {'value':{'my_products':pro_id[0]}} try this.

arsalan
Avtor

the error is resolved and I can view the drop down but they are not filtered . It is showing all values of product.product

Jagdish Panchal

my_products':fields.many2one('product.product','Product', domain="[('categ_id','=',categ1)]") add this in py file upgrade module it will work.

arsalan
Avtor

no , still the values are not filtered . I think product.product will not be there , Since because of product.product its showing all products

Jagdish Panchal

Add this in py file 'my_products':fields.many2one('product.product','Product') and add this in xml file <field name="my_products" domain="[('categ_id','=',categ1)]"/>

arsalan
Avtor

its ok for some categories , like u see I have used union in query just to make sure that I get values filtered in all type of categories therefore this approach is not accepted.

Jagdish Panchal

Your problem is solve ? or not ?

arsalan
Avtor

no my problem is not solved , if I use many2one the values are not filtered and if I use selection field then it will have predefined values

arsalan
Avtor

that was another scenario and it worked for some categories but my query is now working for all categories and bringing filtered products . Only problem here is how to show those values as selection or dropdown list

arsalan
Avtor

can selection field be used for dynamic values. Like I want to return values to selection field. Is that possible?

Jagdish Panchal

I did not get.

arsalan
Avtor

I have like 10 values returning from onchange function . They all are shown on 1 normal field which is weird . I want to use many2one or selection to have a dropdown menu . Thats it .

Jagdish Panchal

You can use many2one field but give widget='selection' in xml file
