Undefined local variable in a partial

Undefined local variable in a partial

I'm new to rails and am having a bit of trouble. I am getting an
undefined local variable or method `answer'
error in my _answer.html.erb partial.
Here is my answers_controller.rb:
class AnswersController < ApplicationController
before_action :set_answer, only: [:show, :edit, :update, :destroy]
def index
@question = Question.find params[:question_id]
@question.answers
end
def show
end
def new
@question = Question.find params[:question_id]
end
def edit
end
def create
@question = Question.find(params[:question_id])
@answer = @question.answers.create(answer_params)
respond_to do |format|
if @answer.save
format.html { redirect_to @comment, notice: 'Answer was successfully
created.' }
format.json { render action: 'show', status: :created, location:
@answer }
else
format.html { render action: 'new' }
format.json { render json: @answer.errors, status:
:unprocessable_entity }
end
end
end
def update
respond_to do |format|
if @answer.update(answer_params)
format.html { redirect_to @answer, notice: 'Answer was successfully
updated.' }
format.json { head :no_content }
else
format.html { render action: 'edit' }
format.json { render json: @answer.errors, status:
:unprocessable_entity }
end
end
end
def destroy
@answer.destroy
respond_to do |format|
format.html { redirect_to answers_url }
format.json { head :no_content }
end
end
and my _answer.html.erb file:
<%=div_for(answer) do %>
<div class="questioncontainer">
<p>
<%= answer.body %>
</p>
</div>
<% end %>
If it matters, my resources :answers is nested in resources :questions.
I appreciate any help!
