suryveyor gem how to output the survey in pdf? - ruby-on-rails

Question

I read about the surveyor gem and in the webpage http://nubic.github.io/surveyor/
Where do I put this line to export the survey report to a pdf?
%li= link_to "PDF", view_my_survey_path(:survey_code => response_set.survey.access_code, :response_set_code => response_set.access_code, :format => 'pdf')
I am not understanding please help.

Answer 1

From the looks of the website that you supplied you should have generated the surveyor:custom controllers. From this it then tells you to install the two following gems
gem 'pdfkit'
gem 'wkhtmltopdf'
But personally I prefer to use wicked_pdf in my opinion. So slightly changing the tutorial a little I would do the following:
rails generate surveyor:custom
This will generate the controllers. So then we can later configure this using the options that wicked_pdf will supply us.
Add the following lines to your Gemfile:
gem 'wicked_pdf' #https://github.com/mileszs/wicked_pdf
gem 'wkhtmltopdf' #https://code.google.com/p/wkhtmltopdf/
In order to have wicked_pdf export correctly you need to have something like this inside an action in your surveyor controller that is generated for you. So you may have something like this in your index action of your surveyor_controller.rb
respond_to do |format|
format.html
format.pdf do
render :pdf => "Survey Report",
:header => {:html => {:template => 'layouts/pdf.html.erb'}}
end
end
From this respond block you could/should I think have the following directory in views - app/views/survey/index.html.erb Inside the index.html.erb you would then have your above link inside this.
<%= link_to "PDF", view_my_survey_path(:survey_code =>
response_set.survey.access_code, :response_set_code =>
response_set.access_code, :format => 'pdf') %>
I have never used the surveyor gem before. But based upon what you have supplied, and what you want I have tried to give as much of a detailed explanation as I can. Hope this potentially helps you or anyone else
Example of Wicked_PDF usage
def index
#bookings= Booking.scoped
booking = #bookings
#user = current_user
if params[:format] == 'pdf'
#bookings= #bookings.where(:day => Date.today.beginning_of_month..Date.today.end_of_month)
end
respond_to do |format|
format.html
format.pdf do
render :pdf => "#{Date.today.strftime('%B')} Overtime Report",
:header => {:html => {:template => 'layouts/pdf.html.erb'}}
OvertimeMailer.overtime_pdf(#user, booking).deliver
end
end
end
View.html.erb
<%= Link_to "Overtime", "booking.png", bookings(:format => "pdf") %>
In order to generate the PDF you need to create a file which has the following extension .pdf.erb what this means is that when the link is processed it processes the embedded ruby code first and then outputs PDF. So in this case I want to do bookings. So I did created in my views/bookings/index.pdf.erb inside this I have the following:
views/bookings/index.pdf.erb
<br />
<% #bookings.each do |booking| %>
<p>
<b>Employee</b>
<%= booking.user.try (:full_name)%>
</p>
<p>
<b>Hospital</b>
<%= booking.hospital.try(:name)%>
</p>
<p>
<b>Day</b>
<%= booking.day.to_s(:long_ordinal) %>
</p>
<p>
<b>Overtime</b>
<%= booking.overtime %>
</p>
<br />
<% end %>
<h2>Total Overtime is <b><%=#bookings.to_a.sum(&:overtime)%></b></h2>
This should give you some core grounds to work off of
