View monthly calendar in Rails


Record until the monthly calendar is displayed on the original application. There is a method to use SimpleCalendar and FullCalendar for the calendar function. This time, we will introduce Simple Calendar.

  1. Install Simple Calendar
  2. Generate Simple Calendar View
  3. Add an appointment to your calendar
  4. Display calendar

1. Install Simple Calendar

Added" gem ‘simple_calendar’, ‘~> 2.0’ to Gemfile スクリーンショット 2020-10-29 8.57.40.png

Run bundle install in the app's directory

2. Generate a Simple Calendar View

Since the calendar cannot be displayed just by installing Gem, view is generated.

Execute command

$ rails g simple_calendar:views

Folders and files are created.

Apply CSS to the calendar Add ** \ * = require simple_calendar ** to the application.css file スクリーンショット 2020-10-29 9.12.31.png

3. Add an appointment to your calendar

Create a model called event using scaffold

Execute command

$ rails g scaffold Event name start_time:datetime

Perform migration to change the database

$ rails db:migrate

4. Display calendar

Since I used scaffold, the code is written in the file of index.html.erb, but I will edit it. Rewrite the index.html.erb file in the events folder.


<%= month_calendar events: @events do |date, events| %>
  <%= date %>

  <% events.each do |event| %>
      <%= %>
  <% end %>
<% end %>

Corrected the appearance and succeeded in displaying the monthly calendar
