Hey there
Code and (longer) quick-start guide can also be found here:
To customize page titles there are many different methods, among the most popular (and best looking) is certainly: #30 Pretty Page Title - RailsCasts, even more there are numerous plugins on github Search 路 title 路 GitHub, so why was there the need to create yet another one?
Because we required a method to have internationalized titles and this
soon became very cumbersome und cludgy 
But well, a few code
examples say more than a thousand words:
# in the layout ... <title><%= h page_title %></title> ...
# then in the translations: en: 聽聽contacts: 聽聽聽聽index: 聽聽聽聽聽聽title: "All contacts"
Thats it. So if /contacts/ is called and then the view contacts/ index.html.erb is rendered, the title "All contacts" is used. To customize the title e.g. to display the contacts name in contacts/ show.html.erb do:
# in contacts/show.html.erb <h1><%= h page_title { @contact.name } %></h1>
It also features some options to change the format, add custom parts
to the output etc. It can be installed as a gem, plugin or git
submodule -> GitHub - lwe/page_title_helper: Simple, internationalized and DRY page titles and headings for Rails. If you find any
issues or problems, I'm sure there are just drop me a line or
create a ticket on github.
Note: this plugin has only been tested and used on Rails 2.3.x.
Gr眉sse, Lukas PS: For those interested: internally the method from railscasts is used to set custom titles. PPS: More examples and a description of all options can be found on github PPPS: It's small LOC = 60, has tests (but Code to Test Ratio is only 1:1.4) and 100% code coverage. PPPPS: Finally some bad news: it relies on some Rails internals to e.g. obtain the first renderer etc., so if those change the plugin might break... so if anyone knows better alternatives (check read_first_render_path and read_page_title_content_block methods)...
