Hey man! Gold! How we can change a type using the migrations?

Is it redundant to use null=true when creating string based fields like TextField or CharField? What would be the difference between empty string and null? Sorry for my english, I am non-native speaker. Thank in advance

Hi Justin, Thanks for the awesome series,
I am using MySql as my DB and when I change something in the model and try to migrate I get error (1067, "Invalid default value for 'id'")". I couldn't find how to fix this. I was trying to make a ForeignKey for a model into another model.
Please help.
