I have a Ruby Sinatra app and I have some code which I need to execute on all routes except for a few exceptions. How do I do this?
If I wanted to execute the code on selected routes (whitelist style) I'd do this:
['/join', "/join/*", "/payment/*"].each do |path|
before path do
#some code
end
end
How do I do it the other way round though (blacklist style)? I want to match all routes except '/join', '/join/*' and '/payment/*'
What I did to make a "before all, except..." filter is use a splat, and then run code on splat conditions.
before '/*' do
unless params[:splat] == 'nofilter' || params[:splat] == 'beta'
redirect '/beta'
end
end
This allowed me to make a before filter with a redirect that didn't create a redirect loop
You can use Regular Expressions for routing in sinatra
for example:
get %r{/hello/([\w]+)} do |c|
"Hello, #{c}!"
end
taken from here. there you can find further informations.
to build and test your regex you can use http://rubular.com/
