Accidentally working with rails wrong name a column of my payments table since I wanted to call it Incoming and I finished it calling ntrantes.
My question is: How can I change the name of the column with the migrations? Or does it have to be manual from the database?
You can do it in 2 ways, if you do it from the database you will have to change it manually and then update it with rails db:schema:dump .
To update your schema , however, you will have to modify the models and controllers. If on the other hand you like to do it with a migration, you will first need to generate it with:
rails generate migration cambiando_columna
... and in the migration that I generate you put the following (it is wrong in rename_colum , it is rename_column ):
class CambiandoColumna< ActiveRecord::Migration[5.0]
def change
rename_column :pagos, :ntrantes, :Entrantes
end
end
... and when you finish modifying this migration simply put the command rails db:migrate for this change to take effect.
