Question

基本上我有一个使用我的用户模型的自定义 UserChangeForm 'Writer'，我想将所有字段的默认值设置为数据库中的当前值（或请求用户的值）。最好的方法是什么？

我尝试在表单中设置默认值，但是在 forms.py

中无法访问请求对象

表格...

class writerChangeForm(UserChangeForm):

    class Meta:
        model = Writer
        fields = ('username', 'email', 'first_name', 'last_name', 'country')
        country = CountryField().formfield()
        widgets = {'country': CountrySelectWidget()}

风景...

class ProfileView(generic.CreateView):
    form_class = writerChangeForm
    template_name = 'diary/profile.html'

感谢任何意见！

最好的方法是覆盖 get_initial() 方法。

class ProfileView(generic.CreateView):
    form_class = writerChangeForm
    template_name = 'diary/profile.html'

    def get_initial(self):
        # get_initial should return dict. They should be rendered in template.
        writer = Writer.objects.get(pk=1) # first get data from database.
        # dictionary key names should be same as they are in forms.
        return {
            'username': writer.username,
            'email': writer.email,
            'first_name': writer.first_name
        }
