How to create new object using data from icalendar file - ruby-on-rails

Question

I have a model called event which attributes are:
string "name"
string "location"
string "lecturer"
date "start_time"
date "end_time"`
I want to take data from icalendar type file and create event instances. How should I do this ? I tried to do a method in events_controller.rb:
def new_method
#ievent_file = File.open("calendar2.ics")
#ievents = Icalendar::Event.parse(#ievent_file)
#ievent = #ievents.first
#ievent = Event.new(name:#ievent.summary,location:#ievent.location, lecturer:#ievent.description, start_time:#ievent.dtstart, end_time:#ievent.dtend)
end
But then what I should do with it ? Should I call this function in view or maybe should I take this code to method called create which looks like this:
def create
#event = Event.new(event_params)
respond_to do |format|
if #event.save
format.html { redirect_to #event, notice: 'Event was successfully created.' }
format.json { render :show, status: :created, location: #event }
else
format.html { render :new }
format.json { render json: #event.errors, status: :unprocessable_entity }
end
end
end

my understanding calendar2.ics have many records, if you want to loop through all the event inside calendar2.ics and save it to your event table (import ics file to event table)
below are sample steps, inside your routes file create one method
resources :events do
collection {
get :transfer_data_from_ics
}
end
inside your events_controller you create 2 methods
def transfer_data_from_ics
# get data from ics
#ievent_file = File.open("calendar2.ics")
#ievents = Icalendar::Event.parse(#ievent_file)
# loop through
#ievents.each do |i_event|
Event.create(
name: i_event.summary,
location: i_event.location,
lecturer: i_event.description,
start_time: i_event.dtstart,
end_time: i_event.dtend)
end
# route back to events list
redirect_to events_path
end
to get the method called you can create menu / button with link_to as follow:
<%= link_to "Transfer data", transfer_data_from_ics_events_path %>
