Using ERb With Your Reports

NOTE: The following recipe is meant for use with Ruport 0.8

If you have a Report which you'd like to use an ERb template with, Report#erb provides a simple way to do this.

Essentially, any string or a filename which matches the pattern /\.r\w+$/ can be used as a template for your report, and the embedded code will be evaluated in the context of your Report.

The following example shows how you might make use of this feature. The rope project which implements this report is attached.

Simple Test ( test/test_report_with_template.rb )

require "test/unit"
require "lib/reports/report_with_template"

class TestReportWithTemplate < Test::Unit::TestCase
  def test_template
    rep = ReportWithTemplate.new
    rep.template = "report.rtxt"
    rep.name = "World"
    assert_equal "Hello World\n", rep.run
  end
end

Report definition ( lib/reports/report_with_template.rb )

require "lib/init"
class ReportWithTemplate < Ruport::Report

  attr_accessor :template, :name
  
  def generate
    erb "templates/#{template}" 
  end
    
end

Template ( templates/report.rtxt )

Hello <%= name %>
