Question

I use sinatra, and have a question that I can’t solve, here is the code:

require 'sinatra'

def url(s)
    get  s do yield end
    post s do yield end
end

url '/' do
    erb :index
end

then, the program tips that: undefined method `erb’ for main:Object

what should I do?

Answer 1

You could try something like this:

require 'rubygems'
require 'sinatra'

def map_url(url, options={}, &block)
  get(url, options, &block)
  post(url, options, &block)
end

map_url '/' do
  erb :index
end
