Dynamically including taglibs. I deployed to production successfully.
Therefore the concept is provem. So some minor bugs related to subsites
corrected in the mean time. So here is the new code.
*config/application.rb*
config.to_prepare do
unless Rails.env.production?
@loaded_include_tags_i ||= 0
if Rails.const_defined? 'Server'
load 'script/include_tags' if @loaded_include_tags_i.even?
@loaded_include_tags_i += 1
end
end
end
You can simply create new tag files, they'll be included on the next
request. Why there is an odd even counter? File changes created by the
script is refiring to_prepare and its entering a loop.
script/include_tags.rb
#!/usr/bin/env ruby
require 'pathname'
def subsite_tags(subsite)
views_dir = 'app/views'
if subsite == 'front'
subsite_views_dir = views_dir
else
subsite_views_dir = File.join views_dir, subsite.to_s
end
tag_files = \
Dir[ File.join subsite_views_dir, 'site_tags*/**/*.dryml' ]+ \
Dir[ File.join subsite_views_dir, '*/view_tags*/**/*.dryml' ]
tags = tag_files\
.map{|f|
File.join File.dirname(f), File.basename(f, '.dryml')}\
.map{|f|
Pathname.new(f).relative_path_from(Pathname.new('app/views')).to_s }
if subsite=='taglibs'
library = 'application'
else
library = subsite + '_site'
end
target = File.join(views_dir, 'taglibs', library +'_tags.dryml')
File.open(target,'w') do |s|
puts
puts target
puts '===='
s.puts "<!-- ==== This is an auto generated file. Do not modify ====
-->"
tags.each do |w|
cmd = %Q{<include src="#{w}"/>}
puts cmd
s.puts cmd
end
end
end
subsite_tags('taglibs')
subsite_tags('front')
subsite_tags('admin') #Of course, if you have such a subsite
subsite_tags('accounting') #Of course if you have such a subsite
Example site structure
