Habtm :uniq causing duplicate inserts? How to update Rails?


#1

Hello Gem experts,

Sorry for asking multiple questions in one post but they are both
related to one problem.

So far I have the following code:

class Member < ActiveRecord::Base
has_and_belongs_to_many :blogs, :uniq=>true

end

class Blog < ActiveRecord::Base
has_and_belongs_to_many :members, :uniq=>true

end

The issue is that :uniq=> true isn’t working and multiple records are
being inserted in blogs_members table when I call the following in
Member class:

def self.create_subscription(member, blog)
  member.blogs.push_with_attributes(blog, :created_at => Time.now)
end

Also what’s the best way to update rails? I tried using

gem update rails but it keeps me at version 1.0?

Is the following functionality as mentioned on
http://www.ruby-forum.com/topic/24128#7157 already implemented?

has_many :books, :through => :authorships

Thank you for your assistance.

Hello,
Any ideas? on why :uniq => true is letting duplicate records go
through?
I even tried creating a new model named Subscription for the relation
but cannot figure out how I can ensure that only one entry exists for a
member to blog relation.

My subscriptions table contains blog_id and member_id fields. Do I
need to add a primary key to this table even if it just holds
relations?

I appreciate your assistance.

Thanks
Frank
