Can't create a LongBlob column from migration

Description

At least under MySQL migration can't create a LongBlob or MediumBlob column. The following code simply create a binary column that is too small for a lot of uses. 

create_table :files do |t|
  t.column :data, :binary, :null => false
end

I'm not sure about the best way to handle it though. Maybe the MySQL adapter could clue in a high limit. Or perhaps the type could be one of :binary, :binary_medium, :binary_large.

  • status changed from new to closed.
  • resolution set to worksforme.

In MySQL 4.1 and above, you can specify the length on a blob or text by using size. It'll automatically expand to the right type. Example: 

create_table :files do |t|
  t.column :data, :binary, :null => false, :size => 400000
end
