Question

我正在使用Django Python中的系统登录，我一直在准备forms.py，views.py和模板本身，但到目前为止，表单无法在模板上加载，任何人都可以帮忙吗？ / p>

Forms.py

class Email_Only_SignUp_Form(forms.Form):
    email = forms.EmailField(initial='Your Email...')

Views.py

def email_only_signup_form(request, template_name):
    if request.method == 'POST':
        signup_form = Email_Only_SignUp_Form(request.POST)

        if signup_form.is_valid():
            email = signup_form.cleaned_data['email']
            username = email

            try:
                #check for duplicate username
                    User.objects.get(username=username)
                    email_error = 'email already exist'
            except:
                #initial creation of user object
                try:
                    import os, random, string

                    length = 13
                    chars = string.ascii_letters + string.digits + '!@$()'
                    random.seed = (os.urandom(1024))
                    password = ''.join(random.choice(chars) for i in range(length))

                    User.objects.create_user(username,
                                             username,
                                             password,
                    )
                    user = User.objects.get(username=username)
                    user_profile=UserProfile(user=user)
                    user_profile.save()

Answer 1

您尚未将signup_form传递给模板。

return render_to_response(template_name,  {'signup_form': signup_form}, context_instance=RequestContext(request))

我不知道locals（）会做什么。

编辑：我刚看到本地人是一个内置的python函数。如果您在模板中明确传递所需的变量会更好。

编辑2：检查它是否是正确的template_name。在模板中，只需打印并查看表单{{signup_form}}即可。看看它是否可用。

Answer 2

您没有退回表格。尝试将视图的最后一行更改为

return render_to_response(template_name, locals(), context_instance=RequestContext(request, {'signup_form' : signup_form ))

Django表单不会出现在模板上
