Ruby Rails - Make Table With created_at Column
t.datetime :created_at, null: false
Just like any other column. Rails will still take care of magic updating because of column name.
Both attempts are okay but contains syntax error.
The problem on the first attempt is that the t. is on datatype not column name.
class CreateLinesSources < ActiveRecord::Migration
def change
create_table :lines_sources do |t|
t.datetime :created_at, null: false
end
end
end
The problem on the second attempt is that remove_column
does not work inside create_table
block. You can move it outside the block and provide correct syntax to remove the column.
class CreateLinesSources < ActiveRecord::Migration
def change
create_table :lines_sources do |t|
t.timestamps null: false
end
remove_column :line_sources, :updated_at, :datetime
end
end
