20140402130040_create_comments.rb

class CreateComments < ActiveRecord::Migration
  def change
    create_table :comments do |t|
      t.string :post_id=integer
      t.text :body

      t.timestamps
    end
  end
end

推荐答案

改为:

class CreateComments < ActiveRecord::Migration
  def change
    create_table :comments do |t|
      t.string :post_id=integer #<= this 
      t.text :body

      t.timestamps
    end
  end
end

使用

class CreateComments < ActiveRecord::Migration
  def change
    create_table :comments do |t|
      t.integer :post_id
      t.text :body

      t.timestamps
    end
  end
end
