Question

I’ve read through a bunch of posts and googled hard but can’t find a set of things to check to solve the following error when I do a:

heroku db:push

I’ve read this answer: Rails migrations over an existing database

But it doesn’t quire solve the problem I’m having. I’m currently getting the following error:

messages:      100% |==========================================| Time: 00:00:00
numbers:         0% |                                          | ETA:  --:--:--
Saving session to push_201109120849.dat..
!!! Caught Server Exception
HTTP CODE: 500
Taps Server Error: PGError: ERROR:  integer out of range

And my Numbers migration looks like this:

class CreateNumbers < ActiveRecord::Migration
  def self.up
    create_table :numbers do |t|
      t.integer :inbound_num
      t.boolean :assigned

      t.timestamps
    end
  end

  def self.down
    drop_table :numbers
  end
end

I am using the integer data type to save mobile phone numbers. I am not sure this is a good idea having read this: What datatype should be used for storing phone numbers in SQL Server 2005?

The thing is the data works great locally so I don’t think I’ve chosen a terrible data-type.

The numbers in the DB I’m pushing look like this:

447786201383

447786201387

447786201389
etc…

Thanks so much in advance!

Answer 1

In your migration, you’ve something like

t.integer :field

But default for Postgresql used on heroku is 4 bytes

So you should change your ints for bigints.

To do that, use the :limit. Example:

t.integer :field, :limit => 8
