问题描述
我正在尝试从OpenERP中另一个DDL的值填充我的DDL(选择).这是我尝试过的代码.
I am trying to populate my DDL(selection) from value of another DDL in OpenERP. Here is the code, that i have tried.
这是我的View XML:
Here is my View XML:
<h1>
<label for="categ1" string="Parent category"/>
<field name="categ1" on_change="Product_Category_OnChange(categ1)" />
</h1>
<newline/>
<h1>
<label for="my_products" string="Products" />
<field name="my_products" />
</h1>
此视图的我的_columns
类似于:
_columns = {
'categ1':fields.many2one('product.category','Parent Category',required=True),
'my_products':fields.many2one('product.product','Products')
}
我的onchange
函数类似于:
def Product_Category_OnChange(self,cr,uid,ids,categ1):
pro_id={}
cr.execute('select ... where parent_id='+str(categ1))
res = cr.fetchall()
for i in range(len(res)):
pro_id[i]=res[i]
return {'domain':{'my_products': pro_id}}
问题是,我没有得到my_products
bu的过滤值,而是得到了my_products
中的所有值.请让我知道,我做错了什么,或者指出正确的方向.谢谢
The problem is, i am not getting filtered values for my_products
bu instead getting all the values that are in my_products
. Plz let me know, what i am doing wrong, or point me to the right direction. Thanks
推荐答案
我认为您只想显示该类别下的产品.
I think you want to show only the products that come under that category.
def Product_Category_OnChange(self,cr,uid,ids,categ1, context=None):
pro_id={}
product_obj = self.pool.get('product.category')
if not categ1:return {}
categ_obj = product_obj.browse(cr, uid, categ1)
return {'domain':{'my_products':[('categ_id','=',categ_obj.id)]}}
或xml
<field name="my_products" domain="[('categ_id','=',categ1)]" />
