Display validation errors in the same style as cripsy error messages

I'm using crispy forms to make my forms look nice and added the following validation:

forms.py

class Meta:
    widgets = {
            'dob': DatePickerInput(
                options={
                    "format": "MM/DD/YYYY",
                    "showClose": False,
                    "showClear": False,
                    "showTodayButton": False,
                }
            ),
    }

def clean(self):
        data = self.cleaned_data
        born = data.get('dob')
        today = date.today()
        age = (today.year - born.year - ((today.month, today.day) < (born.month, born.day)))

        if age < 14:
            msg = ("Sorry, you must be atleast 14 years old")
            self.add_error('dob', msg)

        if age > 110:
            msg = ("You entered a date of birth outside of the accepted range. Please try again.")
            self.add_error('dob', msg)

        return data

models.py

dob = models.DateTimeField('Date of birth (mm/dd/yyyy)', null=True, default=now)

My problem is that this error message displays at the top of the page as a flash message, while other messages (which i did not set but are built into crispy, such as when a user leaves a required field blank) are displayed as a pop up message box under the field the errors related to.

I am wondering how I can make my added validation error appear the same as other in-built crispy error messages, for consistency.

Thank you.

If you are overriding clean method then you can use add_error():

def clean(self):
    data = self.cleaned_data
    age = data.get("age")

    if age < 14:
        msg = "Sorry, you must be atleast 14 years old to study with IPC IELTS."
        self.add_error('age', msg)

    if age > 110:
        msg = "You entered a date of birth outside of the accepted range. Please try again."
        self.add_error('age', msg)

    return data

You can also put validation on your Model or on Form:

from django.core.validators import MinValueValidator,MaxValueValidator
from django.utils.translation import ugettext_lazy as _

class YourModel(models.Model):
    age = models.DecimalField(..., validators=[
        MinValueValidator(14, message=_("Sorry, you must be atleast 
            14 years old to study with IPC IELTS.")),
        MaxValueValidator(110, message=_("You entered a date of birth outside of the 
            accepted range. Please try again."))
    ])

So that you don't need to style it manually for that field.
