I have 3 models
Skill, User, UserSkill
User has_many skills :through => :user_skills
User has_many :user_skills
UserSkill.new # => { :id => nil, :user_id => nil, :skill_id => nil }
us = UserSkill.create(:user_id => 1, :skill_id => 1) # => { :id => nil,
:user_id => 1, :skill_id => 1 }
Why id is nil?
In the database record was created and id is not null...

Because the record had not saved. Call create! instead to raise an exception.
but in general you should create the associations through your model objects.
So for example:
u = User.new
u.skills << Skill.find(1)
u.save!
