A Feed has many Subscriptions

class Feed \< ActiveRecord::Base  
has\_many :subscriptions  
end

class Subscription \< ActiveRecord::Base  
belongs\_to :feed, :counter\_cache =\> true  
belongs\_to :user  
end

This does not work  
ch = Channel.find(:first)  
ch.feeds.create(:user\_id =\> 1, :score =\> 0.0)

user\_id and score columns must be non-null, SQL INSERT sets them NULL.  
Nor does it work with string keys instead of symbols.

This does:  
ch = Channel.find(:first)  
ch.feeds.create do |f|  
f.user\_id = 1  
f.score = 0.0  
end

According to AWDWR 1st and [http://rails.rubyonrails.org/](http://rails.rubyonrails.org/) both should  
behave  
the same. What has changed or I am doing wrong.

TIA,  
Jeffrey

It’s possible that the attributes aren’t getting assigned because  
they’re protected. Do you have attr\_protected or attr\_accessible  
declared anywhere in your model?

Pat,  
Head slap, yes that is precisely the problem. Thanks for seeing into  
my  
blind spot.
