I tried "AddvideoToQuestions video: references"

A question has_many videos. A video belongs_to a question.

Tried to rake db:migrate, and got the following error.

WHATSUP? I'm finally deep diving into coding in rails (my first real language), and this bug has been getting to me.

SQLite3::SQLException: near "references": syntax error: ALTER TABLE "questions" ADD "video" references/Users/davidngo/.rvm/gems/ruby-1.9.3-p429/gems/sqlite3-1.3.7/lib/sqlite3/database.rb:91:in `initialize'

@Marek Lipka -- tried that and tried rake db:migrate again, but still the same error.

Below is the log:

(Apologies -- not familiar with how to present code blocks.

Try this:

bundle exec rails g migration add_video_to_questions video:references

I believe this was already answered in: Rails 3 migrations: Adding reference column?

That being said, I had a similar issue. I cannot tell you what exactly is going wrong, but here is how I got past the issue:

rails g migration add_video_id_to_questions video_id:integer
