Django：如何设置内联模型表单中字段的初始值？

问题描述

我有我认为应该是一个简单的问题。我有一个内联模型表单，我想让一个选择字段具有当前登录用户的默认选择值。看来，我使用Django的Authentication中间件，所以让用户访问 request.user 是一个简单的事情。

然而，我还没有想到的是如何将该用户设置为选择框（ModelChoiceField）中的默认选定值，其中包含列表用户。谁能帮我这个？

解决方案

它可以通过设置所有额外表单的初始值。

  formset = MyFormset（instance = myinstance）
 user = request.user 
 for formset.forms中的表单：
如果'user'不在form.initial中：
 form.initial ['user'] = user.pk 
  

I have what I think should be a simple problem. I have an inline model formset, and I'd like to make a select field have a default selected value of the currently logged in user. In the view, I'm using Django's Authentication middleware, so getting the user is a simple matter of accessing request.user.

What I haven't been able to figure out, though, is how to set that user as the default selected value in a select box (ModelChoiceField) containing a list of users. Can anyone help me with this?

解决方案

This does the trick. It works by setting the initial values of all "extra" forms.

formset = MyFormset(instance=myinstance)
user = request.user
for form in formset.forms:
    if 'user' not in form.initial:
        form.initial['user'] = user.pk
