Question

I‘m a newer in python，django

model：

class Product(model.Model):
    name = models.CharField(max_length = 30)
    warehouse = models.CharField(max_length = 30)

    class Meat:
        unique_together = (('name', 'warehouse'),)

When i submit the form

if the name input field is empty，then I got the message : the field is……

if the name field value and the warehouse field value is equal, then I got the message: …is exist

How can I customize the validation error message(the stronger text)?

You can override error messages in the form:

name = forms.CharField(error_messages={
    'min_length': _('Enter a longer name'),
})

warehouse = forms.CharField(error_messages={
    'invalid': _('Enter a unique combination'),
})

Take a look at the django forms source to see the different error messages you can over ride.
