In my project, on the form, I apply the built in validate\_email validator on a field.

I apply it to one of my form fields, however it throws an error when I run the server.

Here is the code:

` from django.core.validators import MinLengthValidator, MaxLengthValidator, validate_email`

```
from django import forms

class SignupForm(forms.Form):
    email = forms.EmailField(validators=[validate_email(value='Email wrong'), MinLengthValidator(3), 
    MaxLengthValidator(255)], widget=forms.EmailInput(attrs={'placeholder': 'Email Address'}))

```

The error I receive when server is run is:  
**django.core.exceptions.ValidationError: [‘Enter a valid email address.’]**

However when I remove the brackets after validate\_email, everything works ok, however I need them as I want to override the message value displayed. Does anybody know the issue? Thanks.

Adding brackets calls the validator function with that value. It doesn’t replace the error message.

Instead, create [`EmailValidator`](https://docs.djangoproject.com/en/3.0/ref/validators/#django.core.validators.EmailValidator) with a custom message:

```python
... vaildators=[EmailValidator(message="Email wrong')]...

```

This calls the `EmailValidator` _class_ and returns an instance, that then can be called to validate values. For example you can do this to get an error:

```python
EmailValidator(message="Email wrong')('not-an-email')

```

Hope that helps,

Adam
