如何在Django中将客户分配给用户? [英] How to assign a customer to a user in Django?
问题描述
我创建了一个系统，在这个系统中，有多个用户和客户.我要创建一个分配函数.客户应分配给用户.
I created a system and in this system, there are several users and customers. What I want to create an assign function. A customer should assign to a user.
例如，我有一个客户列表.当用户单击按钮时，该用户将看到其他用户的列表并选择其中一个.之后，客户名称将列在所选用户的其他已分配客户列表中.
For example, I have a customer list. When the user clicks a button, the user will see a list that other users and select one of them. After that, the customer's name will be listed in the different assigned customers list of the selected user.
我写了一个代码，并且可以正常工作，但是我无法从客户列表中接触到该用户.我的意思是，当我单击分配"按钮时，它会创建一个新客户.如何获取用户ID或用户名?
I wrote a code and this is working, but I cannot reach user from customer list. What I mean is when I click assign button it create a new customer. How can I reach user id or username?

# Assign
form = AssignForm(request.POST or None)
if form.is_valid():
form.save()
return redirect('user:customer_list')
myFilter = TableFilter(request.GET, queryset=customer_list.all())
context = {
'customer_list': customer_list,
'myFilter': myFilter,

}
return render(request, 'customer_list.html', context)
