View Rails record Associations in modal - ruby-on-rails

Question

In my Rails app I have 3 models Kid, Classroom, and Teacher. Basically, I have a table in my view which lists all the classrooms, when I click on a button I want a modal to pop up that lists the teachers and students assigned to that classroom, as there is an association where a Classroom has_many Teachers and has_many Kids. I have the code ready for the modal, I have copied it below, however I am having a difficult time scoping a specific classroom object to the modal. All help is appreciated!
<div class="modal fade" id="showClassModal" role="dialog">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button>
<h4 id="showClassroomHeader"></h4>
</div>
<div class="modal-body">
<h4>Teachers Assigned</h4>
<ol>
<% #classroom.teachers.each do |teacher| %>
<li><%= teacher.first_name %> <%= teacher.last_name %></li>
<% end %>
</ol>
<br>
<h4>Students</h4>
<ol>
<% #classroom.kids.each do |kid| %>
<li><%= kid.first_name %> <%= kid.last_name %></li>
<% end %>
</ol>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
<% if current_user.admin? %>
<button class="btn btn-warning" id="editClassroomBtn">Edit</button>
<% end %>
</div>
</div>
</div>
EDIT:
Classroom controller:
class ClassroomsController < ApplicationController
before_action :set_classroom, only: [:show, :edit, :update, :destroy]
# GET /classrooms
# GET /classrooms.json
def index
#user ||= current_user
if current_user.admin?
#classrooms = Classroom.all
else
#classrooms = #user.classrooms.all
end
end
# GET /classrooms/1
# GET /classrooms/1.json
def show
classroom = Classroom.find(params[:id])
render :text => classroom.class_desc
end
# GET /classrooms/new
def new
#classroom = Classroom.new
end
# GET /classrooms/1/edit
def edit
end
# POST /classrooms
# POST /classrooms.json
def create
#classroom = Classroom.new(classroom_params)
classroom.user = current_user
respond_to do |format|
if #classroom.save
format.html { redirect_to root_url, notice: 'Classroom was successfully created.' }
format.json { render :show, status: :created, location: #classroom }
else
format.html { render :new }
format.json { render json: #classroom.errors, status: :unprocessable_entity }
end
end
end
# PATCH/PUT /classrooms/1
# PATCH/PUT /classrooms/1.json
def update
respond_to do |format|
if #classroom.update(classroom_params)
format.html { redirect_to root_url, notice: 'Classroom was successfully updated.' }
format.json { render :show, status: :ok, location: #classroom }
else
format.html { render :edit }
format.json { render json: #classroom.errors, status: :unprocessable_entity }
end
end
end
# DELETE /classrooms/1
# DELETE /classrooms/1.json
def destroy
#classroom.destroy
respond_to do |format|
format.html { redirect_to classrooms_url, notice: 'Classroom was successfully destroyed.' }
format.json { head :no_content }
end
end
private
# Use callbacks to share common setup or constraints between actions.
def set_classroom
#classroom = Classroom.find(params[:id])
end
# Never trust parameters from the scary internet, only allow the white list through.
def classroom_params
params.require(:classroom).permit(:class_name, :class_desc, :capacity, :start_range, :end_range)
end
end

Answer 1

As mentioned in the comments section above, adding the modal inside <% #classrooms.each do |classroom| %> did the trick!
