Hi! I start testing Django 1.7beta1. I use MySQL database.
I add new TextField into my model like that:
{{{
class Article(models.Model):
title = models.CharField(max_length=200)
pub_date = models.DateField()
text = models.TextField()
text2 = models.TextField() #new TextField
}}}
When I type "python manage.py makemigrations" I am asked to enter default
value.
But BLOB/TEXT columns can't have a default value and if i will type
something like 'blabla' then after command "python manage.py migrate" i
will see error. I think it is bug :)

Comment (by loic84):
Fixed the name of the commands in the ticket description.
I originally assumed this was an issue before the migrate step, but it's
indeed an SQL issue due to one-off defaults, Django uses db defaults for
these.
The fix for MySQL is to not provide a default for BLOB/TEXT in the
SchemaEditor. Although we'll now need to propagate the default value
manually.
