Association information not being displayed in Rails 4? -

-

the current_user has 1 quiz has questions 1 through 5, entered here:

<%= form_for @quiz |f| %>             <div class="field"> <!-- question 1 name -->                 <%= f.label :q1, "what first question?", :class => "edit_labels", :maxlength => 10 %>                 <%= f.text_field :q1, :placeholder => "question 1",  :style => "text-align: center" %>             </div> ,,,,

created in controller takes place 

def landing @quiz = quiz.new end

in quizzes controller:

def edit @quiz = quiz.find(params:[id]) end  def create @quiz = current_user.build_quiz(quiz_params) if @quiz.save   flash[:success] = "updated"   redirect_to '/' else   render 'new' end end  def quiz_params   params.require(:quiz).permit(:q1, :q2, :q3, :q4, :q5) end   def show  @quizzes = quiz.all  end

now, when try display users:

 /users/index.html.erb  <%= render @users %>

and in partial:

  /users/_user.html.erb    <%= user.username %>    <%= user.quiz.q1 %>    etc...more fields

it works producing usernames, not quiz.q1 specifically, get

undefined method `q1' nil:nilclass

but if type

<%= current_user.quiz.q1 %>

in 'welcome/landing.html.erb', produces correct result.

i appreciate much. thank you.
