Would like to find a way to show Klass.name, Programme.name, Topics.name and Timeslots.starts_at in the calendar. Currently only managed to show "Topic" instead of topics.name (see link) and Timeslots.starts_at. Attempted other methods but keep getting No Method Error. Appreciate suggestions on how to resolve this.

Here is the views of the calendar.
app/views/timeslots/month.html.erb/_month_views.html.erb
<div id="timeslots">
<h2 id="month">
<%= link_to "<", date: @date.prev_month %>
<%= @date.strftime("%B %Y") %>
<%= link_to ">", date: @date.next_month %>
</h2>
<%= calendar @date do |date| %>
<%= date.day %>
<% if @timeslots_by_date[date] %>
<ul>
<% @timeslots_by_date[date].each do |timeslot| %>
<li><%= link_to timeslot.topics.name %>) <%= link_to timeslot.starts_at %></li>
<% end %>
</ul>
<% end %>
<% end %>
</div>
<br/>
app/controllers/timeslots_controller.rb
def month
@timeslots = Timeslot.all
@timeslots_by_date = @timeslots.group_by {|i| i.starts_at.to_date}
@date = params[:date] ? Date.parse(params[:date]) : Date.today
end
Routes are
Rails.application.routes.draw do

get '/login', to: 'sessions#new'
post '/login', to: 'sessions#create'
get '/logout', to: 'sessions#destroy'

end

end

The models are all has_many :through associations with belongs_to declared in all the 3rd models.
class Klass < ActiveRecord::Base
belongs_to :intake

The calendar helper module is as below
app/helpers/calendar_helper.rb
module CalendarHelper
def calendar(date = Date.today, &block)
Calendar.new(self, date, block).table
end
class Calendar < Struct.new(:view, :date, :callback)
HEADER = %w[Sunday Monday Tuesday Wednesday Thursday Friday Saturday]
START_DAY = :sunday
delegate :content_tag, to: :view
def table
content_tag :table, class: "calendar" do
header + week_rows
end
end
def header
content_tag :tr do
HEADER.map { |day| content_tag :th, day }.join.html_safe
end
end
def week_rows
weeks.map do |week|
content_tag :tr do
week.map { |day| day_cell(day) }.join.html_safe
end
end.join.html_safe
end
def day_cell(day)
content_tag :td, view.capture(day, &callback), class: day_classes(day)
end
def day_classes(day)
classes = []
classes << "today" if day == Date.today
classes << "notmonth" if day.month != date.month
classes.empty? ? nil : classes.join(" ")
end
def weeks
first = date.beginning_of_month.beginning_of_week(START_DAY)
last = date.end_of_month.end_of_week(START_DAY)
(first..last).to_a.in_groups_of(7)
end
end
end
