rails form: don't show child in form, if already has this child
Person.rb:
class Person < ApplicationRecord
has_many :skills
end
Skill.rb:
class Skill < ApplicationRecord
belongs_to :person
validates_uniqueness_of :name, :scope => :person_id
end
I made skills nested in Routes.rb:
resources :people do
resources :skills
end
end
Now, when creating a new skill for the client in clients/1/skills/new I do not want to be able to select a skill that the client already has. How can it be done? Here is my current input field:
= f.select :skill_id, Skill.all.map{|c| [c.name, c.id]}, {include_blank: true}

I don't know which Rails version you're running, but you could make a scope for the Skill class.
scope :remaining, ->(name) { where.not(name: name) }
Then update your view:
= f.select :skill_id, Skill.remaining(@person.skills.map(&:name)).map { |c| [c.name, c.id] }, { include_blank: true }
That's untested, not sure if you'd need to .map the :name but you get the idea. Also change :name to :id if that suits better for your use case (I'm not sure if you enforce skill uniqueness across the board or just per-user).
It looks a little clunky for your view, though, so you could throw it onto the Skill class assuming you have the right columns.
def self.remaining # you're mapping the skill, not the client
where.not(id: person.skill_ids).map { |s| [s.name, s.id] }
end
Then the view'd just be:
= f.select :skill_id, Skill.remaining, { include_blank: true }
As an aside, I'm going to guess the /clients versus /people are the same thing with different names only on SO, otherwise that's going to cause headaches and/or break.
