表单字段不会显示在浏览器中。只显示提交按钮。
views.py 代码:
def vote(request, pk):
# check if request is post
if request.method == 'POST':
# create a form and populate it with data from request
form = forms.Vote(request.POST)
if form.is_valid():
fact = Fact.objects.get(pk=pk)
fact.votes += int(form.cleaned_data['vote'])
fact.save()
return HttpResponseRedirect(reverse(
'facts:detail',
args=(pk,)
))
else:
form = forms.Vote()
return render(request, 'facts/fact_detail.html', {'form': form})
模板(fact_detail.html)代码:
<form method='POST'>
{% csrf_token %}
{{ form }}
<input type="submit" value="vote" />
</form>
表单类(forms.py)代码:
VOTE_CHOICES = [
(1, 'upvote'),
(0, 'downvote')
]
class Vote(forms.Form):
vote = forms.ChoiceField(choices=VOTE_CHOICES, widget=forms.RadioSelect())

投票方法的 views.py 在本地初始化表单变量,然后将其作为参数传递。
def vote(request, pk):
form=""
//rest of the code//
return render(request, 'facts/fact_detail.html', {'form': form})

我建议从django文档检查通用编辑视图我认为它有解决方案 [https://docs.djangoproject.com/en/1.11/ref/class-based-views/generic-editing/#createview][1]
