Hello to all , I have 3 fields which in my module page.2 are for product categories and 1 for product. The categories fields consist of different categories. Now I want to add filter so that what ever category I set in the field, only those product should list in the products field . It is a type of sorting or filtering. I dont have much idea of using filter in such a scenerio under form view. Here is my code.py:

class deg_form(osv.osv):
    _name = "deg.form"
    _columns = {
         'categ1':fields.many2one('product.category','Parent Category'),
         'categ2':fields.many2one('product.category','Child Category'),
         'my_products':fields.many2one('product.product','Products',size=64),

            }


deg_form()

and here is its xml:

<record id="mywin_form_view" model="ir.ui.view">
            <field name="name">mywin.form</field>
            <field name="model">deg.form</field>          
            <field eval="7" name="priority"/>
            <field name="arch" type="xml">
                <form string="FORM DATA" version="7.0">

                     <h1>
                       <label for="categ1" string="Parent category"/>
                           <field name="categ1" />
                     </h1>

                     <h1>
                       <label for="categ2" string="Child category"/>
                           <field name="categ2" />
                     </h1>
<newline/>

                     <h1> 
                       <label for="my_products" string="Products" domain = "[('categ1','=',True)]"/> 
                           <field name="my_products"/> 
                     </h1>


                 <button name="show_product" string="SHOW PRODUCT" type="action"/>
                 </form>
             </field>
    </record>

please help me fix this

Hello

You can put filter in dynamic fashion

example:

.py file format:

class my_class(): columns={'categ_id1':fields.many2one('product.category',Category),'product_id':fields.many2one('product.product',Products)}

def my_onchange_func(self,cr,uid,ids,categ_id,context):

if categ_id:

    pro_tmp_obj=self.pool.get('product.template')

    prod_obj=self.pool.get('product.product')

    prod_categ_ids=pro_tmp_obj.search(cr,uid,['categ_id','=',categ_id])
    pro_ids=prod_obj.search(cr,uid,['product_tmpl_id','in',[prod_categ_ids])



    return {'domain':{'product_id':[('id','in',pro_ids)]}}

my_class()

################
XML file format:

<field name="categ_id1" on_change="my_onchange_func"/>

<field name="product_id"/>

Try this: This shows the products that have category set from categ1 and categ2 field 

<h1> 
      <label for="my_products" string="Products" /> 
      <field name="my_products" domain = "[('categ_id','in',[categ1, categ2])]"/> 
</h1>

For a button to call a function in PY FILE, we use type="object"

<button name="show_product" string="SHOW PRODUCT" type="object"/>

Try this

'my_products':fields.many2one('product.product','Products',size=64, domain="[('categ_id', '=', categ1)]")

Coz the many2one field for product_category in product_template is categ_id and product_product is based on product_template.

yes thanks again . as you saw I have two categ fields . 1 is parent and other is child . But I want to do like when I set a categ in 1st field, then the 2nd field should just show the child of that parent , not all . Do I have to write function for this , to search for the child of that parent?

Jagdish Panchal

did not get you

arsalan

means like when I set a category in first field . and then when I try to search any category in the other field , then it should show only the child categories of that parent category which I set in the 1st field

Jagdish Panchal

set domain for that.

but I can't filter through parent categories. look if I give values in all 3 categories then its ok . but if I try to give only parent_id , then it doesnot show anything although it should show everything in that parent_id
