Question

I’m trying to create a simple application with Ruby on Rails. I’ve created this scaffold:

rails generate scaffold Pic title:string content:blob description:text

and when I try to migrate db with rake db:migrate I’m getting this error:

rake aborted!
An error has occurred, this and all later migrations canceled:

undefined method `blob' for #<ActiveRecord::ConnectionAdapters::TableDefinition:0xb74f8ec4>

When I write say text instead of blob it works normally. So what’s the problem with blob ?

Answer 1

The keyword is binary, not blob.

rails generate scaffold Pic title:string content:binary description:text
