This thing is driving me mad.
So, I’m following a typical exercise with Authors, Messages and Topics.
I’m coding with Rails 3.0.7 and Ruby 1.8.7.
The relation I want to do is really simple :
Author has_many :messages
Messages belongs_to :author
Topic :has_one :author
the catch comes when on the console I’m inserting manually objects and
then verifying them.
So, for example, if I create a message named:
message1 = Message.new(:text => ‘this is a message’)
and an author like
jack = Author.new(:name => ‘Jack’)
the next thing I will try to do shall be:
message1.author = jack
So at this point, if I want to verify I do this:
=> #<Author id: 8, name: “jack”, created_at: “2011-06-11 16:29:56”,
updated_at: “2011-06-11 16:29:56”>
Everything is fine.
But if I try to do the inverse, so :
I obtain this :
ActiveRecord::StatementInvalid: SQLite3::SQLException: no such column:
messages.author_id: SELECT “messages”.* FROM “messages” WHERE
(“messages”.author_id = 8)
and I don’t understand what it means.
Do you have any idea about where am I mistaken?
