基于Django类的视图 - 具有两个模型形式的UpdateView - 一个提交

Question

我有一个包含用户列表的页面,并希望能够单击链接以更新其个人资料.点击"更新"后,我应该可以使用一个提交按钮在一个页面中编辑用户名,名字,...电子邮件,电话号码,部门等.我通过使用两个表单完成了这个,一个用于User,另一个用于额外信息.ListView,DeleteView和CreateView与这两种形式完美配合,但不适用于UpdateView.我无法使用初始数据实例化这两个表单.

问题是:如何用数据实例化两个表单？覆盖self.object？get_form_kwargs？什么是最优雅的解决方案？

UpdateView类如下所示.我不是在寻找'复制 - 粘贴'解决方案,但可能会指出我正确的方向.

谢谢.

电话号码,部门在名为Employee的模型中定义.

class Employee(models.Model):
    user = models.OneToOneField(User)
    phone_number = models.CharField(max_length=13, null=True)
    department = models.CharField(max_length=100)

模板是:

{% extends "baseadmin.html" %}
{% load crispy_forms_tags %}

{% block content %}
<h4>Edit a user</h4>
<form action="" method="post" class="form-horizontal">
    <legend>Edit a user</legend>
    {% crispy form %}
    {% crispy form2 %}
    <div class="form-actions">
        <input type="submit" class="btn btn-primary" value="Save">
            <a href="{% url 'client_list' %}" class="btn">Cancel</a>
    </div>
</form>
{% endblock content %}

视图类是:

class ClientUpdateView(UpdateView):
    model = User
    form_class = ClientsUserForm
    second_form_class = ClientsForm
    template_name = 'admin/client_update.html'

    def get_context_data(self, **kwargs):
        context = super(ClientUpdateView, self).get_context_data(**kwargs)
        context['active_client'] = True
        if 'form' not in context:
            context['form'] = self.form_class(self.request.GET)
        if 'form2' not in context:
            context['form2'] = self.second_form_class(self.request.GET)
        context['active_client'] = True
        return context

    def get(self, request, *args, **kwargs):
        super(ClientUpdateView, self).get(request, *args, **kwargs)
        form = self.form_class
        form2 = self.second_form_class
        return self.render_to_response(self.get_context_data(
            object=self.object, form=form, form2=form2))

    def post(self, request, *args, **kwargs):
        self.object = self.get_object()
        form = self.form_class(request.POST)
        form2 = self.second_form_class(request.POST)

        if form.is_valid() and form2.is_valid():
            userdata = form.save(commit=False)
            # used to set the password, but no longer necesarry
            userdata.save()
            employeedata = form2.save(commit=False)
            employeedata.user = userdata
            employeedata.save()
            messages.success(self.request, 'Settings saved successfully')
            return HttpResponseRedirect(self.get_success_url())
        else:
            return self.render_to_response(
              self.get_context_data(form=form, form2=form2))

    def get_success_url(self):
        return reverse('client_list')

如果您需要，您应该能够使用“实例”kwarg 从现有模型实例化表单。例子：

context['form'] = self.form_class(self.request.GET, instance=request.user)
