Simple script to convert ERB files to Haml

May 29th, 2009 — Rails, Ruby

A simple script to convert .erb files from current directory to .haml :

#!/usr/bin/ruby
 
Dir.glob("*.html.erb").each do |erbname|
  hamlname = erbname.gsub(".html.erb", ".html.haml")
  system "/usr/bin/html2haml #{erbname} #{hamlname}"
end

File uploads in import scripts

May 21st, 2009 — Rails, Ruby

Simulating file uploads in your scripts or from console can be done really simple using Rail’s ActionController::TestUploadedFile from action_pack.

Example code:

require 'action_controller/test_process'
 
class ImportExternalData
 ...
  def import_data
    ...
    page.attachments << PageAttachment.new(
      :uploaded_data => fake_file_upload(filename, mime_type),
      :title => title,
      :description => description)
    ...
  end
 
 
protected
  def fake_file_upload(path, mime_type = nil, binary = false)
    ActionController::TestUploadedFile.new(
      path,
      mime_type,
      binary
    )
  end
end

Excerpt from ActionController::TestUploadedFile’s comments:

Essentially generates a modified Tempfile object similar to the object
you’d get from the standard library CGI module in a multipart
request. This means you can use an ActionController::TestUploadedFile
object in the params of a test request in order to simulate
a file upload.
