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
paginates_per 6
end
class User < ActiveRecord::Base
has_and_belongs_to_many :projects
end
Thank you for the help.

If you have a project in @project for example, then to get all the
associated users you just use
@project.users
That is the magic of Rails.
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.

Also have a look at the Rails Guide on Associations, and all the others
in fact.

Colin,
@project.users
That is the magic of Rails.
This magic I already know, but my question was, I want to show All user
associated in a project in a select tag.
But I don’t know if I make a each in @project.users and do a each or has
something already done with rails.

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.
Thank you again

The code you have will show all projects because you have specified
Project.all. 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? Please be a bit more
specific about what you want to see on the page.

Also by completely removing the previous message here you have lost

Previously you showed a select that used Project.all to get the
projects to display. 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.
Colin
Do u mean double select ？
You have two select drop down, and u want the second one contains only
the users which belongs to the selected project in the first select drop
down ?
