django - ValidationError message doesn't appear in my own form -

i created custom registration form:

class myregistrationform(usercreationform):     mobile = models.charfield(max_length=16)     address = models.charfield(max_length=100)      class meta():         model = customuser         fields = ['username', 'password1', 'password2', 'first_name', 'last_name', 'email', 'mobile', 'address']      def clean_mobile(self):         mobile = self.cleaned_data['mobile']         if customuser.objects.filter(mobile=mobile).exists():             raise validationerror('mobile exists')         return mobile      def save(self, commit=true):         user = super(myregistrationform, self).save(commit=false)         user.mobile = self.cleaned_data['mobile']         user.address = self.cleaned_data['address']         if commit:             user.save()         return user 

and in template, don't write `{{form}}', instead use bootstrap template registration. looks like:

<form class="form-horizontal" action="{% url 'register' %}" method="post">             {% csrf_token %}             <div class="control-group">                 <label class="control-label" for="username1" >Ім'я користувача <sup>*</sup></label>                 <div class="controls">                     <input type="text" id="username1" placeholder="Нік" name="username">                 </div>             </div>              <div class="control-group">                 <label class="control-label" for="password_1" >Пароль <sup>*</sup></label>                 <div class="controls">                     <input type="password" id="password_1" placeholder="Введіть пароль" name="password1">                 </div>             </div>              <div class="control-group">                 <label class="control-label" for="password_2" >Повторіть пароль <sup>*</sup></label>                 <div class="controls">                     <input type="password" id="password_2" placeholder="Повторіть пароль" name="password2">                 </div>             </div> 

but when clean_mobile method called , raise validationerror, no errors aren't showed. how solve issue? or maybe can use in template {{form}} need use bootstrap css?

you need include {{ form.mobile.errors }} display errors mobile field.

see working form templates docs more information.

you might want investigate django crispy forms, makes easy render bootstrap forms.
