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() })

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