如何检查两种形式的验证在django形式？ [英] how check two forms validation in django form?

问题描述

我正在使用Django身份验证系统，并且还有一个关于用户的模型：

  class user（models.Model） ：
 user = models.OneToOneField（User）
 user_code = models.IntegerField（max_length = 3）
 phone = models.IntegerField（max_length = 10）
 task = models.ForeignKey （任务）
 class Meta：
 unique_together =（'user_code'，'task'）
 def __unicode __（self）：
 return str（self.user_code）
  

所以我做了两个表单进行用户注册（form.py）：

$ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $（（（（（（（（（（（（（（（（（（（（（（（（（（（（（（（（（（ ）

class Form4（forms.ModelForm）：
class Meta：
model = user

现在在我看来，我想发送两个表单到模板并提交两者。一切都很好，但提交后，我无法检查表单验证？这是我的观点：

  def add_new_user（request）：
如果request.method =='POST'：＃如果表单已经提交... 
 user_form = userForm（request.POST）＃django用户
 form = Form4（request.POST）＃我的模型用户
如果user_form.is_valid（）和form.is_valid（）：＃所有验证规则通过**编辑** is_valide 
 user_name = user_form.cleaned_data ['username'] 
 password = user_form.cleaned_data ['password'] 
 name = user_form.cleaned_data ['first_name'] 
 user_id = form.cleaned_data ['user_code'] 
 email = user_form.cleaned_data ['email'] 
 phone = form.cleaned_data ['phone '] 
 task = form.cleaned_data ['task'] 
 else：＃** added ** form invalid statement 
 return render（request，'student / form4.html'，{'形式'：form，'user_form'：user_form}）
 
尝试：＃**从有效的语句移动** 
做somthing ... 
除了ValueError：
做somthing ... 
 else：
 form = Form4（ ）
 user_form = userForm（）
＃未绑定的形式
返回渲染（请求，'student / form4.html'，{'form'：form，'user_form'：user_form}）
  

这是我的模板（form4.html）：

 < form name =myFormaction ={％url'student：add_new_user'％}onsubmit =return validateForm4（）方法= POST > 
 {％csrf_token％} 
< div id =form-data> 
 {{form.non_field_errors}} 
 {{user_form.username}} {{user_form.username.errors}} 
< label for =id_user_name>用户名： /标签><峰; br> 
 {{user_form.password}} {{user_form.password.errors}} 
< label for =id_password> password：< / label>< br> 
 {{user_form.first_name}} {{user_form.first_name.errors}} 
< label for =id_name>名字：< / label>< br> 
 {{user_form.email}} {{user_form.email.errors}} 
< label for =id_email>电子邮件：< / label>< br> 
 
 {{form.user_code}} {{form.user_code.errors}} 
< label for =id_email>使用ID：< / label>< br> 
 
 {{form.phone}} {{form.phone.errors}} 
< label for =id_phone>电话号码：< / label>< br> 
 
 {{form.task}} {{form.task.errors}} 
< label for =id_task> task：< / label>< br> 
< input type =submitvalue =register/>< br> 
< / div> 
< / form> 
  

但是对于验证都返回False。如何检查验证？

ANSWER ：

我添加哪个字段想从用户和用户。并将我的form.py更改为：

  class userForm（forms.ModelForm）：
 class Meta：
 model = User 
 fields =（'username'，'password'，'first_name'，'email'）
 widgets = {'password'：forms.PasswordInput（），} 
 class Form4（forms.ModelForm）：
 class Meta：
 model = user 
 fields =（'user_code'，'phone'，'task'）
  

感谢所有评论和答案。

解决方案

尝试在每个表单中添加不同的前缀

 ＃GET 
 user_form = userForm（prefix =one ）
 form = Form4（prefix =two）
 
＃POST 
 user_form = userForm（request.POST，prefix =one）
 form = Form4 （request.POST，prefix =two）
  

I am using the Django authentication system and have another model which is about user:

class user(models.Model):
    user = models.OneToOneField(User)
    user_code=models.IntegerField(max_length=3)
    phone=models.IntegerField(max_length=10)
    task=models.ForeignKey(task)
    class Meta:
        unique_together = ('user_code', 'task')
    def __unicode__(self):
        return str(self.user_code)

so I made two forms for user registeration(form.py):

class userForm(forms.ModelForm):
    class Meta:
        model=User
        widgets = {'password': forms.PasswordInput(),}

class Form4(forms.ModelForm):
    class Meta:
        model=user

Now in my view I want to send two forms to template and submit both of them. Everything is well but after submitting I can't check form validation? this is my view:

def add_new_user(request):
    if request.method == 'POST': # If the form has been submitted...
        user_form = userForm(request.POST) # django User
        form = Form4(request.POST)      # my model user
        if user_form.is_valid() and form.is_valid():          # All validation rules pass **edited** is_valide
            user_name=user_form.cleaned_data['username']
            password = user_form.cleaned_data['password']
            name=user_form.cleaned_data['first_name']
            user_id = form.cleaned_data['user_code']
            email = user_form.cleaned_data['email']
            phone = form.cleaned_data['phone']
            task = form.cleaned_data['task']
        else:  # **added** form invalid statement
            return render(request, 'student/form4.html', {'form': form,'user_form':user_form})

        try:  #**moved from valid statement**
            do somthing...  
        except ValueError :
            do somthing...       
     else:
        form = Form4()
        user_form=userForm()
        # An unbound form
        return render(request, 'student/form4.html', {'form': form,'user_form':user_form})

this is my template(form4.html):

<form name="myForm" action="{% url 'student:add_new_user' %}" onsubmit="return validateForm4();"     method="post">
        {% csrf_token %}
        <div id="form-data">
        {{ form.non_field_errors }}
            {{ user_form.username }}{{ user_form.username.errors }}
            <label for="id_user_name">user name:</label><br>
            {{ user_form.password }}{{ user_form.password.errors }}
            <label for="id_password">password:</label><br>
            {{ user_form.first_name }}{{ user_form.first_name.errors }}
            <label for="id_name">first name:</label><br>
            {{ user_form.email }}{{ user_form.email.errors }}
            <label for="id_email">email:</label><br>

            {{ form.user_code }}{{ form.user_code.errors }}
            <label for="id_email">use ID:</label><br>

            {{ form.phone }}{{ form.phone.errors }}
            <label for="id_phone">phone number:</label><br>

            {{ form.task }}{{ form.task.errors }}
            <label for="id_task">task:</label><br>
            <input type="submit" value="register" /><br>
        </div>
    </form>     

But it returns False for both validation. How can I check validation?

ANSWER:

I add which field I want from User and user. and change my "form.py" to :

class userForm(forms.ModelForm):
    class Meta:
       model=User
       fields = ('username', 'password','first_name','email' )
       widgets = {'password': forms.PasswordInput(),}
class Form4(forms.ModelForm):
    class Meta:
        model=user
        fields = ('user_code', 'phone','task' )

thanks for all comments and answer.

解决方案

Try add different prefixes to each of forms

# GET
user_form = userForm(prefix="one")
form = Form4(prefix="two")

# POST
user_form = userForm(request.POST, prefix="one")
form = Form4(request.POST, prefix="two")
