6) Now, remove the row which was giving you the error, class y(Models.model):
a = models.CharField(default='Let us say default')
b = ....
Yes, remove the one giving you the error, for example, it is saying

OperationalError at /admin/blog/blogpost/ no such column: table_table.a
then remove the thing coming after the dot
a in this case
remove it so that only 
b = ....

Then you can fill the nulled part up with something
