rename column in db rails

Renaming a Column in Ruby on Rails

rails generate migration RenameOldColumnToNewColumn

class RenameOldColumnToNewColumn < ActiveRecord::Migration[6.0]
  def change
    rename_column :table_name, :old_column, :new_column
  end
end

Replace table_name, old_column, and new_column with the actual table name, old column name, and new column name. After running the migration, the column will be renamed in the database.
