Rails Migration: Bigint on PostgreSQL seems to be failing?

Question

Trying to create a table with a bigint column creates a standard integer column instead. What could be going wrong? I don\'t know where to start looking.

I\'m using

Answer 1

In rails 4.2 + you can use like:

create_table :table_name do |t|
   t.bigint :really_big_int
end

Answer 2

For some reason the create table doesn't like bigint. You can, however do it with add_columm using the bigint data type:

add_column :table_name, :really_big_int, :bigint

Then you don't need that limit stuff.

Answer 3

This works in Rails 4

t.column :really_big_int, :bigint

Answer 4

I was able to create a bigint using t.column. This is useful if you want to control the column order in the table.

create_table :table_name do |t|
  t.string :other_column
  t.column :really_big_int, :bigint
  .
  .
  t.timestamps
end

I'm using Rails 3.2.12 with pg gem version 0.15.1 (x86-mingw32).

Answer 5

Rails 5.0.0.1 it works:

  def change
    create_table :huge do |t|  
      t.integer :big_bastard, limit: 8
    end
  end
