Openerp中的Onchange功能 [英] Onchange function in Openerp
问题描述
在account.invoice.line中有一个名为form_type的选择字段.它具有三个选择选项:
I have a selection field in account.invoice.line named form_type. It has three selection options:
1) form_a
2) form_b
3) form_c
account.invoice.line中还有一个名为 flag 的整数字段.选择form_c时,标志值应设置为1;否则,标志值应设置为1.否则,如果选择了form_a或form_b,则标志值应设置为0.对于上述情况,我编写了一个 onchange 函数,但它不起作用.有人可以帮我吗?我的代码有什么问题?
There is also an integer field named flag in account.invoice.line. When form_c is selected, the flag value should be set to 1; otherwise, if either form_a or form_b is selected, the flag value should be set to 0. I wrote an onchange function for the above case but it's not working. Can someone help me out? What is wrong in my code?
def onchange_form_type(self, cr, uid, ids, invoice, context=None):
val={}
flag=0
invoice = self.pool.get('account.invoice.line').browse(cr, uid, invoice)
for invoice in self.browse(cr, uid, ids, context=context):
if invoice.form_type=="form_c":
flag="1"
else:
flag="0"
print flag
val = { 'flag': flag, }
return {'value': val}
account.invoice.line中用于onchange的XML代码是:
My XML code in account.invoice.line for onchange is:
<field name="form_type" on_change="onchange_form_type(form_type)"/>
推荐答案
在变更函数中,您无需调用对象的浏览功能,因为这些值尚未存储在数据库中.另外,您正在将"form_type"值传递给函数,而不是对象ID(因为浏览器接受对象ID).
In your on-change function you don't need to call the browse function of the object, because the values are not stored in the database yet. Also, you are passing the "form_type" value to the function and not the object id(as browse accepts object id).
因此,下面将是满足预期要求的on_change函数:
So, below will be the on_change function, for the expected requirement:
def onchange_form_type(self, cr, uid, ids, form_type, context=None):
val={}
flag=0
if form_type == 'form_c':
flag="1"
val = { 'flag': flag }
return {'value': val}
