Hello,

I have a problem with nested resources.

Ich made following entries in the routes.rb:

  map.resources :projects do |project|     project.resources :iterations do |iteration|       iteration.resources :tasks     end   end

when I use link_to:

<%= link_to 'Show', project_iteration_task_path(task.iteration.project, task) %>

following is displayed:

http://localhost:3000/projects/2/iterations/117/tasks/32

The problem is, that the IDs of iterations and task are interchanged. The real iteration_id = 32 and the real task_id = 117.

do sombebody knows a solution or what's worn with the code?

Thanks for every answer!

You can try the alternative syntax:

map.resources :tasks map.resources :iterations, :has_many => [:tasks] map.resources :projects, :has_many => [:iterations]

isn't it safer to use the models to define the relationships?

Hello Rudi,

I've got an answer form the german forum:

The solution from Thomas Baustert,

project_iteration_task_path(task.iteration.project, task.iteration, task)

and it works fine:-)

I only wanted to generate better readable URLS like:

http://localhost:3000/projects/2/iterations/36/tasks/140

When I used

   map.resources :projects, :has_many => [ :iterations]

   map.resources :iterations, :has_many => [ :tasks]

the same URL for tasks looked like this:

http://localhost:3000/iterations/36/tasks/140

but there is no conclusion to the project_id.

Thank you for your answer

Regs,
