未调用 CreateView 中的 Django form_valid() 和 form_invalid()

Django form_valid() and form_invalid() in CreateView not called

我目前正在使用 django 的 CreateView post 数据到数据库。不幸的是,我想保存和执行自定义逻辑的方法 form_valid() 从未被调用过。我在另一个堆栈溢出响应中读到 form_invalid() 可能会发现问题,但我无法调用该方法。似乎调用的唯一方法是 get(),我覆盖了它并在其中放入了打印语句。我做错了什么?

class view.py

中的声明
class TeamCreate(CreateView): # Manipulate and use this Method instead of create_team
    model = Team
    # form_class = create_team_form
    fields = ['team_name', 'sport', 'sport_season']
    success_url = '/'

    def get(self, request, *args, **kwargs):
        self.user = request.user
        print 'happening1'
        return super(TeamCreate, self).get(request, *args, **kwargs)


    def form_valid(self, form):
        print 'happening2'
        # form.instance.save()
        # self.user.teams.add(form.instance)
        form.save()
        return super(form_valid, self).form_valid(form)

    def form_invalid(self, form):
        print "form is invalid"
        return http.HttpResponse("form is invalid.. this is just an HttpResponse object")

相关模板代码

{% block content %}
<form action="" method=”POST”>
     {% csrf_token %}
     {{ form|crispy }}
     <input class="btn btn-primary" type="submit" value="Create" />
</form>

看来POST两边的引号根本就不是引号,而是鬼鬼祟祟的忍者断命标记。 “对”。我要睡觉了。

试试这个

<form action="" method="post">
