问题 I wrote a webform using Sinatra and Haml that will be used to call a Ruby script. Everything seems fine except for one thing: I need to pass an argument to a Haml view file from the Sinatra/Ruby script. Here is a part of my code: #!/usr/bin/env ruby require 'rubygems' require 'sinatra' require 'haml' get '/' do haml :index end post '/' do name = params[:name] vlan = params[:vlan] tmp = nil tmp = %x[./wco-hosts.rb -a -n #{name} -v #{vlan}] if tmp.include?("Error") haml :fail else haml :success

问题 I am pretty new to ruby and sinatra but basically I have this route: put '/user_list/:user_id' do puts request.params["model"] end and it returns the following {"password":"36494092d7d5682666ac04f62d624141","username":"nicholas","user_id":106,"firstname":"Nicholas","email":"nicholas@macpractice.com","is_admin":0,"lastname":"Rose","privileges":""} I am now having a hard time accessing values of each of those. It doesn't really seem to be in hash format so I can't really do request.params[

问题 I’ve created a sudoku puzzle creator / solver and need a bit of help with some CSS to style it. Typically they are styled like this: . Some naming I’m using. Cell - each individual cell which contains a single number. Box - one of the 9 boxes each containing 3 x 3 cells Grid - the entire 9x9 playing area. My html is partially generated by my ruby / Sinatra app (at least the repeating DIV’s are) and structured as such : #game { margin-left: auto; margin-right: auto; width: 360px; } .cell input

问题 I'm working on my first Sinatra app and I have an hard time getting parameters from a post request. I'm using MiniTest::Spec and my spec looks like payload = File.read("./spec/support/fixtures/payload.json") post "/api/v1/verify_payload", { payload: payload }, { "CONTENT_TYPE" => "application/json" } last_response.body.must_eql payload And this is my route namespace '/api/v1' do post '/verify_payload' do MultiJson.load(params[:payload]) end end The spec fails because last_response.body is

问题 I am very new to ruby / rails and have an issue that I have not been able to figure out but feel it should be relatively simple to fix.

问题 I'm having trouble changing the path that LESS uses to include imports. My routes file has get "/css/main.css" do less :main, :paths => ["public/css"] end However, if I include an external less file with @import in my stylesheet the LESS compiler cannot find the file. I've placed a copy in both the views path and public/css directories, but it still can't find it. It CAN however find plain .css files in public\css . 回答1: I hit this today, and was able to solve it like so: require 'less'

问题 My ssh keys are definitely set up correctly, as I'm never prompted for the password when using ssh. But capistrano still asks for a password when deploying with cap deploy . It doesn't ask for the password when I setup with cap deploy:setup though, strangely enough. It would make the deployment cycle so much smoother without a password prompt. Specifics: I'm deploying a Sinatra app to a Dreamhost shared account (which uses Passenger). I had followed a tutorial for doing so long back, which

问题 I need to make some methods with Sinatra that should look like: http//:localhost:1234/add?string_to_add But when I declare it like this: get "/add?:string_to_add" do ... end it doesn't see the string_to_add param. How should I declare my method and use this parameter to make things work? 回答1: In a URL, a question mark separates the path part from the query part. The query part normally consists of name/value pairs, and is often constructed by a web browser to match the data a user has entered
