[英]Populate DropDown List dynamically
I am trying to populate my DDL(selection) from value of another DDL in OpenERP. 我正在尝试从OpenERP中另一个DDL的值填充我的DDL(选择)。 Here is the code, that i have tried.
这是我尝试过的代码。
Here is my View XML: 这是我的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>
My _columns
for this view is like: 我对此视图的
_columns
如下:
_columns = {
'categ1':fields.many2one('product.category','Parent Category',required=True),
'my_products':fields.many2one('product.product','Products')
}
my onchange
function is like: 我的
onchange
函数就像:
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}}
The problem is, i am not getting filtered values for my_products
bu instead getting all the values that are in my_products
. 问题是,我没有得到过滤值
my_products
蒲式耳,而不是让所有的都在值my_products
。 Plz let me know, what i am doing wrong, or point me to the right direction. 请让我知道,我做错了什么,或者指出正确的方向。 Thanks
谢谢
I think you want to show only the products that come under that category. 我认为您只想显示该类别下的产品。
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)]}}
or in xml 或在xml中
<field name="my_products" domain="[('categ_id','=',categ1)]" />
Like this way. 喜欢这种方式。 It works my side
它在我这边工作
{'domain':{'my_products':[('id','=',categ1)]}}
Syntax is like this, 语法是这样的,
def Product_Category_OnChange(self,cr,uid,ids,categ1, context=None):
pro_id={}
product_obj = self.pool.get('product.category')
print product_obj.browse(cr, uid, categ1)
cr.execute('select * from product_category where parent_id='+str(categ1))
res = cr.fetchall()
for i in range(len(res)):
pro_id[i]=res[i]
return {'domain':{'my_products':[('id','=',categ1)]}}
Update: 更新:
I understand, First of all, you have to make one Custom module. 我了解,首先,您必须制作一个Custom模块。
put following code in your .py file. 将以下代码放入您的.py文件中。
class product(osv.osv):
_inherit = 'product.product'
def name_get(self, cr, uid, ids, context=None):
res = []
cr.execute('select ... where parent_id='+str(ids[0]))
resource = cr.fetchall()
for r in resource:
res.append((r.id, r.name)) # My assumption
return res
