MySQL bigint auto_increment primary_key is not dumped correct in db/schema.rb #19232
Description
Hi,
I have tried to create a table with an bigint as primary_key and auto_increment for a MySQL database.
My Migration was
class CreateTests < ActiveRecord::Migration
def change
create_table :tests, id: false do |t|
t.integer :id, limit: 8, auto_increment: true, primary_key: true
t.string :name
end
end
end
Auto_increment and primary_key have been ignored.
CREATE TABLE `tests` (
`id` bigint(20) DEFAULT NULL,
`name` varchar(255) COLLATE utf8_unicode_ci DEFAULT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;
The db/schema.rb looked like
create_table "tests", id: false, force: :cascade do |t|
t.integer "id", limit: 8
t.string "name", limit: 255
end
A second try
class CreateTests < ActiveRecord::Migration
def change
create_table :tests do |t|
t.string :name
end
change_column :tests, :id, :integer, limit: 8, auto_increment: true, primary_key: true
end
end
The MySQL-Table was build correct
CREATE TABLE `tests` (
`id` bigint(20) NOT NULL AUTO_INCREMENT,
`name` varchar(255) COLLATE utf8_unicode_ci DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;
But the db/schema.rb looked like
create_table "tests", force: :cascade do |t|
t.string "name", limit: 255
end
And after a rake db:reset resets the column was changed back to integer instead of bigint.
Best
