⟩ Please explain what is a Rails Migration? Write up a short example of a simple Rails Migration with a table called customers, a string column called name, and a text column called description.?
Initiating the command c:rubyapplication>ruby script/generate migration table_name will create a Rails Migration. A Rails Migration can be used to create, drop, or remove tables and columns. A potential solution is provided below.
class CreateCustomers < ActiveRecord::Migration
def up
create_table :customers do |t|
t.string :name
t.text :description
t.timestamps
end
end
def down
drop_table :customers
end
end
