My understanding:
- You have
projects
- Each project has many
questions
&project_applications
- Each question belongs to a
project
, has manyanswers
throughproject_applications
For each project, you'd like to create applications with the applicable answers. Here's what I'd do:
Models
class Project < ActiveRecord::Base
has_many :project_applications
has_many :questions
end
class Question < ActiveRecord::Base
belongs_to :project
has_many :answers
has_many :project_applications, through: :answers
end
class Answer < ActiveRecord::Base
belongs_to :question
belongs_to :project_application
end
class ProjectApplication < ActiveRecord::Base
belongs_to :project
belongs_to :student
has_many :answers
has_many :questions, through: :project
accepts_nested_attributes_for :answers
def self.build
application = self.new
application.answers.build
end
end
Controller
#app/controllers/project_applications_controller.rb
def new
@projectapplication = ProjectApplication.build
@project = @projectapplication.project
end
def create
end
private
def application_params
params.require(:project_application).permit(:application, :attributes, :here, answer_attributes: [:content])
end
Views
#app/views/project_applications/new.html.erb
<%= form_for @projectapplication do |f| %>
<%= f.text_field :application_fields %>
<% @project.questions.each do |question| %>
<%= f.fields_for :answers, question do |answer| %>
<%= answer.hidden_field :question_id, question.id %>
<%= answer.text_field :content, placeholder: question.content %>
<% end %>
<% end %>
<% end %>
Process
This works by creating a new project_application
, sending answers directly to the answer
model. Because answers
are directly associated with questions
, and projects
through questions
, you should be able to get it working without passing any more data
This might not work outright, but I'm sure with some tweaking it will deliver the desired result
