python'module'对象不可调用

Question

我正在尝试将表单添加到我的django视图中。问题是，我不能宣布上课。这就是问题：

Addform.py：

from django import forms

class AddSubjectForm(forms.Form):
def __init__(self):
    pass

name = forms.CharField(max_length=200)

Views.py：

from django.http import HttpResponse
from django.template import Context, loader
from AddSubject.AddForm import AddSubjectForm

def index(request):
    template = loader.get_template('AddSubject/index.html')

    if request.method == 'POST':
        form = AddSubjectForm()
        context = Context({
                       'form': form,
                       })
    else:
        form = AddSubjectForm()
            context = Context({        
                       'form': form,
                       })

    return HttpResponse(template.render(context))

最后我收到了错误：

我一直在寻找Google的解决方案，但每个回复都是关于文件名的。它对我不起作用：/你有任何想法，为什么AddSubjectForm不起作用？

Answer 1

根据我的评论，您的导入声明有误。

你写的是

from AddSubject.AddForm import AddSubjectForm

将其更改为

from AddFrom import AddSubjectForm

使用from做的是遍历所有模块，以便它可以从相对模块导入。但由于AddSubject不是AddSubject中的包，而是从模块加载并将包视为模块。
