Django表单不会呈现
我的表单代码：
class PlanForm(forms.Form):
a = forms.CharField(widget=forms.TextInput(attrs={"class", "add-up"}))
b = forms.CharField(widget=forms.TextInput(attrs={"class", "add-up"}))
class Media:
javascript=('test.js', )
我的查看代码：
def plan_detail(request):
if request.method == "POST":
return render(request=request,
template_name='pasteur/plan_detail.html',
dictionary={ 'message': 'This was a post request. WTF!' })
else:
return render(request=request,
template_name='pasteur/plan_detail.html',
dictionary={ 'form': PlanForm() })

正如错误所述， {"class", "add-up"}是一个集合。 你需要一本字典： {"class": "add-up"} 。
