nested user-specific forms in rails - mysql

Question

I'm attempting to build a nested form for my Devise users to fill out and then later update. The form consists of two models; one for questions and another for users. My controller looks like this:
class LegalFormsController < ApplicationController
before_action :set_legal_form, only: [:show, :edit, :update, :destroy, :answers]
respond_to :html
def index
#legal_forms = LegalForm.all
respond_with(#legal_forms)
end
def show
respond_with(#legal_form)
end
def new
#legal_form = LegalForm.new
respond_with(#legal_form)
end
def edit
end
def create
#legal_form = LegalForm.new(legal_form_params)
#legal_form.save
respond_with(#legal_form)
end
def update
#legal_form.update(legal_form_params)
respond_with(#legal_form)
end
def destroy
#legal_form.destroy
respond_with(#legal_form)
end
def answers
#users = User.all
#questions = #legal_form.questions
end
private
def set_legal_form
#legal_form = LegalForm.find(params[:id])
end
def legal_form_params
params.require(:legal_form).permit(:name,
:questions_attributes => [:id, :content,
:answers_attributes =>[:id, :content, :participant_id]
])
end
end
and the view for the answers is (currently) as follows:
<h1><%= #legal_form.name %> Answers</h1>
<%= form_for(#legal_form) do |f| %>
<% #users.each do |user| -%>
<h3><%= user.id %></h3>
<table>
<thead>
<tr>
<td>Questions</td>
<td>Answer</td>
</tr>
<tbody>
<% #questions.each do |question| -%>
<tr>
<td><%= question.content %></td>
<td>
<%= f.fields_for :questions, question do |q| -%>
<%=q.fields_for :answers, question.answers.find_or_initialize_by(user: #user) do |a| -%>
<%= a.text_area :content %>
<%= a.hidden_field :user_id, :value => current_user %>
<% end -%>
<% end -%>
</td>
</tr>
<% end -%>
</tbody>
</table>
<% end -%>
<div class="actions">
<%= f.submit %>
</div>
<% end =%>
As you can see, this currently brings up all questions/answers for all users.
My question is two-fold:
How might I set this up to just bring up the current user?
Using this line <%= a.hidden_field :user_id, :value => current_user %>, I am attempting to provide the current user id for each answer saved to the answers database under user_id. However, it doesn't seem to be working. What might I be missing?
Many thanks for any help on this!
As requested, below are my model associations
class Answer < ActiveRecord::Base
belongs_to :question
belongs_to :user
end
class LegalForm < ActiveRecord::Base
has_many :questions
accepts_nested_attributes_for :questions
end
class User < ActiveRecord::Base
# Include default devise modules. Others available are:
# :confirmable, :lockable, :timeoutable and :omniauthable
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable
has_many :answers
has_many :questions, through: :answers
end
class Question < ActiveRecord::Base
belongs_to :legal_form
has_many :answers
has_many :users, through: :answers
accepts_nested_attributes_for :answers
end

Answer 1

You can set user_id value like this
<%= f.hidden_field :user_id, value: current_user.id %>
