我正在尝试使用 Django 表单允许 Django 用户输入他们最喜欢的三个兴趣。该错误发生在模板呈现期间,它显示为 {{form.as_ul}}

代码如下:

reg_interests.html

{% block content %}

<br><br>
<h1>Choose the 3 things that interest you most!</h1>

<form method="post" action="/reg_interests/">
{% csrf_token %}
{{form.as_ul}}
<br>
<p class="submit"><input class="btn btn-default" type="submit" name="commit" value="Continue"></p>
</form>

{% endblock %}

views.py

def reg_interests_view(request):
if request.POST:
form = InterestsForm(request.POST, request=request)
if form.is_valid():
form.save(request)
return redirect('/reg_video/')

args = {}
args['form'] = InterestsForm(request=request)

return render(request, 'login/reg_interests.html', args)

表单.py

class InterestsForm(RequestModelForm):
interest1 = forms.ChoiceField(choices=[(1, "Option 1"), (2, "Option 2")])
interest2 = forms.ChoiceField(choices=[(1, "Option 1"), (2, "Option 2")])
interest3 = forms.ChoiceField(choices=[(1, "Option 1"), (2, "Option 2")])

class Meta:
model = Interest
fields = ('interest1', 'interest2', 'interest3')

def __init__(self, request):
self.user = request.user

def save(self, commit=True):
interest = super(InterestsForm, self).save(commit=False)
interest.user = self.user
interest.interest1 = self.cleaned_data['interest1']
interest.interest2 = self.cleaned_data['interest2']
interest.interest3 = self.cleaned_data['interest3']

if commit:
interest.save()

return interest

我认为表单有问题,但我不知道如何或为什么需要定义_errors。 Django 本身不应该处理这个问题吗?如果不是,我该如何定义 _errors

最佳答案

此代码根本无法工作,因为您覆盖了表单的 __init__ 方法,因此 a) 您只接受一个 request 参数 - 而不是任何表单期望的其他内容,例如 datainitial - 并且 b) 您永远不会调用父类(super class) init 方法来初始化表单代码的其余部分所期望的内容。您需要保留签名并调用 super。

def __init__(self, *args, **kwargs):
request = kwargs.pop('request')
self.user = request.user
super(InterestsForm, self).__init__(*args, **kwargs)
