###I have model named Publisher in models.py file.###
###And based on this model, a modelForm has made, called "RegistrationForm".###
###Which renders form on registration.html template.###
<br /> <br />**This is code of registration.html**
<pre><code>
```
<body>
<div class="container">
{% load my_filters %}
<div class="row">
<div class="col-md-6 offset-md-3">
{% if registered %}
<h1>Thank you for registering!</h1>
{% else %}
<h1>Register Here</h1>
<h3>Just fill out the form.</h3>
<form enctype="multipart/form-data" method="POST">
{% csrf_token %}
{{ reg_form.non_field_errors }}
<div class="fieldWrapper">
<div class="form-group">
{{ reg_form.name.errors }}
<label for="{{ reg_form.name.id_for_label }}" >Name:</label>
{{ reg_form.name|addclass:'form-control' }}
</div>
</div>
<div class="fieldWrapper">
<div class="form-group">
{{ reg_form.email.errors }}
<label for="{{ reg_form.email.id_for_label }}">Email:</label>
{{ reg_form.email|addclass:'form-control' }}
</div>
</div>
<div class="fieldWrapper">
<div class="form-group">
{{ reg_form.contact.errors }}
<label for="{{ reg_form.contact.id_for_label }}">Contact:</label>
{{ reg_form.contact|addclass:'form-control' }}
</div>
</div>
<div class="fieldWrapper">
<div class="form-group">
{{ reg_form.password.errors }}
<label for="{{ reg_form.password.id_for_label }}">Password:
</label>
{{ reg_form.password|addclass:'form-control' }}
</div>
</div>
<div class="fieldWrapper">
<div class="form-group">
{{ reg_form.confirm_password.errors }}
<label for="{{ reg_form.confirm_password.id_for_label }}">Confirm
Password:</label>
{{ reg_form.confirm_password|addclass:'form-control' }}
</div>
</div>
<input type="submit" name="" value="Register">
</form>
{% endif %}
</div>
</div>
</div>
</body>
```

### I am NOT using crispy forms just manually rendering Django forms and using manual template tag to add classes to fields.
**This is the template tag in used to add classes to form fields**
<code><pre>
```
@register.filter(name='addclass')
def addclass(value, arg):
return value.as_widget(attrs={'class': arg})
```
</code></pre>
**This is the model in models.py**
<code><pre>
```
class Publisher(models.Model):
id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False)
name = models.CharField('Name', max_length=50)
email = models.EmailField('Email', unique=True)
password = models.CharField('Password', max_length=50)
contact = models.CharField('Contact #', max_length=16, unique=True, validators=[
RegexValidator(
regex=r'^\+?1?\d{9,15}$',
message="Phone number must be entered in the format '+123456789'. Up to 15 digits allowed."
),
],)
def __str__(self):
return self.name
```
</code></pre>
**This is the form in forms.py file**
<code><pre>
```
class RegistrationForm(forms.ModelForm):
password = forms.CharField(widget=forms.PasswordInput())
confirm_password = forms.CharField(widget=forms.PasswordInput())
class Meta():
model = Publisher
fields = ('name','email','contact','password')
def clean(self):
cleaned_data = super(RegistrationForm, self).clean()
password = cleaned_data.get("password")
confirm_password = cleaned_data.get("confirm_password")
if password != confirm_password:
raise forms.ValidationError(
"password and confirm_password does not match"
)
```
</code></pre>
**This is the view in views.py file**
<code><pre>
```
def registration(request):
registered = False
if request.method == 'POST':
reg_form = RegistrationForm(data=request.POST)
if reg_form.is_valid():
user = reg_form.save()
user.save()
registered = True
else:
#Now issue is this printing statement working fine and printing errors on console.But
#errors are not showing on template.
print(reg_form.errors)
else:
reg_form = RegistrationForm()
return render(request, 'seller/registration.html',
{'reg_form': RegistrationForm,
'registered': registered
})
```
</code></pre>
我已经看到了所有堆栈溢出并尝试了许多操作，但没有一个可以帮助我在表单模板上获取我的错误（尽管django控制台上会打印出密码不匹配和联系电话错误等错误） （如views.py文件的else语句中所定义）。
用错误的数据填写表格后，按“提交”按钮将刷新表格而不显示错误。在用正确的数据填写表格后，用户将被注册（显示模板中定义的“感谢您注册”）。我知道我在做或想念的东西一定很愚蠢。请让我知道。
