Question

i am new to Ruby on Rails.
I am trying to make a one to many association. I have a “Project” and the Project should have many “Taskbundle”.
That is looking fine.

Now i want to show on the page only the taskbundles filtered for that selected project.

I made this in the ProjectController class:

def select
    puts "==Projects=="
    puts params[:id]

    @project = Project.find{params[:id]}
    puts @project.id
    session[:project_id] = @project.id

    puts session[:project_id]

    redirect_to taskbundles_path
end

I am getting there without problem, but the find method finds the project with the id 3 and not the project with the id 4 ? I checked, the project with id 4 exists.

Output

==Projects==
4
3
3


Started GET "/projects/select/4" for 127.0.0.1 at 2013-01-05 20:19:03 +0100
Processing by ProjectsController#select as HTML
  Parameters: {"id"=>"4"}

Redirected to http://localhost:3000/taskbundles
Completed 302 Found in 3ms (ActiveRecord: 0.0ms)

I have no idea where i did a mistake?

I think you got a syntactic problem: @project = Project.find{params[:id]} should be @project = Project.find(params[:id]). The ID needs to be passed as an argument. Your code creates a ruby block.
