Hello, I have two tables with association HABM, projects and users, and
in projects I want to show all users that was associated to the project.
I have try with this:
<%= select( "user", "id", Project.all.collect { |p| [
p.name, p.id ] } )
%>
But only show all my projects, but Iz don''t know who show only the user
in a determinated project.
class Project < ActiveRecord::Base
has_attached_file :image, :styles => { :medium =>
"300x200>", :thumb
=> "100x100>" }
has_many :item
has_and_belongs_to_many :users
belongs_to :category
belongs_to :color
belongs_to :icon
# kaminari
# https://github.com/amatsuda/kaminari
paginates_per 6
end
class User < ActiveRecord::Base
has_and_belongs_to_many :projects
end
Thank you for the help.

I suggest that you work right through a good tutorial such as railstutorial.org (which is free to use online), then you will get a grasp of the basics of Rails.

I don''t understand exactly what you want to show. Do you want the users to appear in a select box or what? Do you have a particular project? Is it in a variable?

Hello Colin, thank you for Ur attention. I have a model Project, in my projects I can create items, in this project I can Select various user, that will be available in my items to distribute that users that I select to make part of my project. But when I try to make a select of all users that are in this project, I can''t because I don''t know very well rails yet, and don''t know if have something already done or I will have to improvise.

Now you say you have a particular project (let us assume, since though I asked you did not answer the question) that it is in @project. Then all you have to do is use a select similar to the one you already had, but use @project.users instead of Project.all. Obviously you have to change the contents of the collect block also as it will be receive users instead of projects. How are you getting on with working through railstutorial.org? You should be well on the the way through it by now. If you had completed it you would not have needed to ask this question.
