This is an extremely simple Active Record association I am trying to create and it is frustrating that is is not being made successfully.
I have two models, post and user. User.rb has nothing but has_many :posts
and Post.rb has nothing but belongs_to :user
. I have run rake db:migrate and verified that there is a user_id column in my posts table.
When I go to the console, though, I am unable to make an association between new objects.
First, I make a new User instance like max = User.create(:name=>"Max")
Next, I make a new Post instance like post = Post.create(:user_id=>1, title=>"FirstPost")
I then try and type max.posts
but get a NoMethodError undefined method 'post='
If I try and set up the association like max.post = post
, I get the same error.
Lastly, I tried adding attr_accessor :posts
to the User model.
Now, I can type max.posts
, but I am just getting nil
.
What am I missing here?
That's because there's no 'post=' method in User.
Try the following:
max = User.create(:name=> "Max")
max.posts.create(:title => "FirstPost")
max.posts
As an alternative way:
max = User.create(:name=> "Max")
post = Post.new(:user => max, :title => "FirstPost")
post.save
max.posts
