问题 I have a modular Sinatra app. I'm setting some custom variables in my configure block and want to access these settings in my model. The problem is, I get a NoMethodError when I try and access my custom settings from MyModel . Standard settings still seem to work fine though. How can I make this work? # app.rb require_relative 'models/document' class App < Sinatra::Base configure do set :resource_path, '/xfiles/i_want_to_believe' end get '/' do @model = MyModel.new haml :index end end #

问题 I have a Sinatra application using the Sequel gem against a sqlite3 database. I've been developing on a MacBook Pro running Mavericks.

问题 I created a small chat application in Sinatra and jQuery on heroku. It simply inserts a message to a database when user submits it. And also downloads new messages every 2 seconds. After a few minutes of testing it stopped working and I received an email form heroku: Hi, We noticed that the gisekchat app had a large number of connections open to the shared database.

问题 Normally when I run a rails app from the console during development I can just press Ctrl + C and it exits. Then I can run the app again, thus bouncing it and effecting changes. I am running a sinatra app. I just run the ruby file. $: ruby myapp.rb When I press Ctrl + C , however, it won't stop the app. I've had to bring up the Ubuntu System Monitor and kill the Ruby process. Very annoying. Anyone seen this/dealt with this before? 回答1: I installed the 'thin' gem and it works fine. Apparently

问题 I have a Sinatra app I plan on hosting on Heroku. This application, in part, scrapes a lot of information from other pages around the net and stores the information to a database. These scrapping operations are a slow process, so I need them to run in another thread/process separate from my Sinatra app. My plan is just to have a button for each process that I can click and the scrapping will take place in the background. I'm unsure what's the best way to do this, complicated by what Heroku

问题 I am having a problem requesting a random number from random.org using jQuery. When I'm using a static page and the following javascript, I don't have any issues getting random numbers. However, I am hosting a Sinatra app on Heroku (also, when running my app locally in production using Thin) I get "(website) is not allowed by Access-Control-Allow-Origin." function raffler(){ var rowCount = $('#winnerTable tr').length; $('#winnerButton').click(function() { $.get("http://www.random.org/integers

问题 I'm trying to setup sidekiq with my sinatra application, and I'm having trouble starting up the sidekiq workers to run in the daemon mode, with a configuration file.

For now, I'm just trying to the get things to work correctly via the command line, and then

问题 I have a Ruby class that basically authenticates a user to an LDAP directory as follows. The DirectoryUser class is using the net/ldap gem to do this. When called the class returns either a 'true' if the user is authenticated or 'false' if not. >>DirectoryUser.authenticate('user', 'password') #True I want to use this mechanism to protect my routes in a basic Sinatra application for multiple users. Is there a recommended way to do this that follows best practise? Could somebody show how this
