Sinatra Extension: redirect with flash
Shortly: sinatra-redirect-with-flash provides redirect helper that can set proper flash (rack-flash) before the
redirection
In fact, every time you set a flash parameter the very next step is often to perform your redirect:
post '/posts/?' do
@post = Post.new(params)
flash[:notice] = 'The post was successfully created'
redirect "/posts/#{@post.id}"
end
With sinatra-redirect-with-flash you can do one-line redirects. For instance, to rewrite the above example:
post '/posts/?' do
@post = Post.new(params)
redirect "/posts/#{@post.id}", :notice => 'The post was successfully created'
end
Example
require 'rubygems'
require 'sinatra'
require 'rack-flash'
gem 'sinatra-redirect-with-flash'
require 'sinatra/redirect_with_flash'
use Rack::Flash
enable :sessions
post '/sessions/new' do
redirect '/secret', :notice => 'Logged in' #predefined keys are: :notice, :error, :warning, :alert, :info
end
get '/foo' do
redirect '/bar', 301, :notice => 'redirect with 301 code'
end
get '/archive' do
redirect '/posts/', :flash => {:my_msg => 'Moving on!'}
end
