Duplicate column name after altering a field - mysql

Question

I added a textfield "field2" to a model and later modified it to a ForeignKey. After which when I try to run migrations, i get duplicate column name for field2. How can this be resolved. Also, i have one more field which is a foreignkey.
Here is my table:
class dummy(models.Model):
field1 = models.ForeignKey(Table1)
field2 = models.ForeignKey(Table2)
field2 was a textfield earlier. Then I modified it to point to another table, making it a foreignkey and then when I run migrations, the duplicate column error appears. How can this be resolved?
DB being used is mySQL
makemigrations and sqlmigrate works fine. migrate is showing up error:
./manage.py migrate

Try this instead
python manage.py migrate --fake-initial
