Short answer: your form needs to submit it.

Typically one does this by having routes that look like

resources projects do
resources :tasks
end

then new_project_task_path(some_project) will be /projects/123/tasks/
new

and you'll get params[:project_id] set to 123

if you set @project based on this and make your form something like

form_for [@project, Task.new] do |f|
...

then the form will be posted to /projects/123/tasks and you will once
again have params[:project_id] set to 123 for you.
