Help on getting multiple answers on a polls app

Hello community,

I’m working on a polls app and the the user would answer to 3 types of
Open answers;
Multiple Choice with only one option to select (radio buttons);
Multiple Choice with many options to select (checkboxes).

i’ve already done the first and the second type of question, but i’m
struggling with the checkboxes.

This are my models:


class Answer < ActiveRecord::Base
belongs_to :reply
belongs_to :question
belongs_to :possible_answer


class Poll < ActiveRecord::Base
validates_presence_of :title

has_many :questions
has_many :replies


class PossibleAnswer < ActiveRecord::Base
belongs_to :question


class Question < ActiveRecord::Base
belongs_to :poll

has_many :possible_answers
has_many :answers

accepts_nested_attributes_for :possible_answers, reject_if: proc {
|attributes| attributes[‘title’].blank? }


class Reply < ActiveRecord::Base
belongs_to :poll
has_many :answers

accepts_nested_attributes_for :answers

In the views I have a reply/new.html.erb that already work for radio and
open answer questions, by rendering the partial by kind:

<%= @poll.title %>

<%= form_for [ @poll, @reply ] do |f| %>
<%= f.fields_for :answers do |c| %>
<%= render c.object.question.kind, c: c %>
<% end %>

<%=f.submit ‘Finish poll’, class: ‘btn btn-primary’%>

<% end %>

and the partial for the checkbox:

<%= c.label :value, c.object.question.title %>

<% c.object.question.possible_answers.each do |possible_answer| %>

<%= check_box_tag( 'possible_answer_id['+']', %> <%= possible_answer.title %> <%= c.hidden_field :question_id %>

<% end %>

and the partial for the radio buttons:

<%= c.label :value, c.object.question.title %>

<% c.object.question.possible_answers.each do |possible_answer| %>

<%= c.radio_button :possible_answer_id, %> <%= possible_answer.title %> <%= c.hidden_field :question_id %>

<% end %>

This is my data base model:

for now i can reply to a poll and answer to the 3 kind of questions but
the checkboxes kind won’t save to the answers table

Probably I have to use has_many through association in the answers model
but I’m not getting how. Can someone help me?
