I’m new to Rails, and am following the getting started guide on their website.
I’m getting an error when I run $ rake db:migrate in section: http://guides.rubyonrails.org/getting_started.html#generating-a-model
It worked for the first time in section: http://guides.rubyonrails.org/getting_started.html#running-a-migration
So I don’t know what is wrong.
When I run $ rake db:migrate
== CreateComments: migrating =================================================
-- create_table(:comments)
rake aborted!
An error has occurred, this and all later migrations canceled:
private method `test' called for #<ActiveRecord::ConnectionAdapters::TableDefinition:0x007f83a27503c8>
Tasks: TOP => db:migrate
(See full trace by running task with --trace)
So I followed the instructions to run it with the --trace argument; I was wondering if anyone has a clue what it means, and what the issue is?
** Invoke db:migrate (first_time)
** Invoke environment (first_time)
** Execute environment
** Invoke db:load_config (first_time)
** Invoke rails_env (first_time)
** Execute rails_env
** Execute db:load_config
** Execute db:migrate

Tasks: TOP => db:migrate
This is the migration code generated:
class CreateComments < ActiveRecord::Migration
def change
create_table :comments do |t|
t.string :commenter
t.test :body
t.references :post
t.timestamps
end
add_index :comments, :post_id
end
end
Looks like when you ran the generator you said ‘test’ instead of ‘text’ for body.
Should have been: $ rails generate model Comment commenter:string body:text post:references
Rake doesn’t know what type t.test is…it would have been t.text
