ruby on rails - Combine scoped fields_for and one additional form rendering -

-

let's i'm writing simple todo application. there 3 hardcoded projects user able add tasks (using fields_for method) basically, form looks that:

# task.first_project, task.second_project , task.third_project scopes # retrieving tasks, belongs chosen project.  = form_for setup_project(@project) |f|   h3 first project's tasks:   = f.fields_for :tasks, f.object.tasks.first_project |ff|     = ff.text_field :title     = ff.hidden_field :project_id, value: 1    h3 second project's tasks:   = f.fields_for :tasks, f.object.tasks.second_project |ff|     = ff.text_field :title     = ff.hidden_field :project_id, value: 2    h3 third project's tasks:   = f.fields_for :tasks, f.object.tasks.third_project |ff|     = ff.text_field :title     = ff.hidden_field :project_id, value: 3

i have form helper adding 1 empty task form @ end of task forms list:

  def setup_project(project)     1.times { project.tasks.build }     project   end

and that's main problem. code form helper works perfect when i'm using fields_for without scopes. when i'm adding them, additional form build not shown.

please note: above example simplified version of i'm programming. please not advice me rewrite app have more dynamical projects adding functionality or that. trust me, needs work in such strange way :)

thank help!

i've managed make working using following code:

# task.first_project, task.second_project , task.third_project scopes # retrieving tasks, belongs chosen project.  = form_for @project |f|   h3 first project's tasks:   = f.fields_for :tasks, setup_tasks(f.object.tasks.first_project) |ff|     = ff.text_field :title     = ff.hidden_field :project_id, value: 1    h3 second project's tasks:   = f.fields_for :tasks, setup_tasks(f.object.tasks.second_project) |ff|     = ff.text_field :title     = ff.hidden_field :project_id, value: 2    h3 third project's tasks:   = f.fields_for :tasks, setup_tasks(f.object.tasks.third_project) |ff|     = ff.text_field :title     = ff.hidden_field :project_id, value: 3

form_helper:

def steup_tasks(tasks)   tasks << tasks.build end

but have no idea if that's proper solution. if know better, please share :)
