Rails Migration Error w/ Postgres when pushing to Heroku

Question

I\'m trying to perform the following up migration to change the column \"number\" in the \"tweet\" model\'s table

class ChangeDataTypeForTweetsNumber < Ac         


        

Answer 1

Same as above but a little bit more concise:

change_column :yourtable, :column_to_change, 'integer USING CAST("column_to_change" AS integer)'
