Here's my Heroku logs (some values anonymized): The only manifestation I'm aware of is when my friend tries to log in using Safari on his iPhone 5. His user account was created right about 6 months ago. I'm 99% sure that he accessed the site just fine with his phone at that time. Since then he hasn't logged in and I'm not aware of any changes I've made to the login/auth codes. Yesterday I had him hit my site

I have this application.js file in a backend (node.js) var app = require('http').createServer(); var io = require('socket.io'); var redis = require('redis').createClient(); var _ = require('underscore')._; io = io.listen(app); io.configure(function() { io.set("transports", ["xhr-polling"]); io.set("polling duration", 10); io.set("close timeout", 10); io.set("log level", 1); }) redis.subscribe('rt-change');

Everything was perfectly fine before I update to 3.1.0 Guys, I am going to lose controll now, help me. 回答1: Make sure that you're setting the correct content-type and that your controllers respond to the specified format. This often happens if the request content-type is set to 'application/json' and your controller doesn't have either respond_to :json declared or a

I was hoping someone could explain the difference between using a scope in an ActiveRecord model and just using a class method (ie self.some_method ) From what I can gather, a scope is always expected to return a relation, whereas a class method doesn't necessarily have to. Is this true? For instance, I thought it would make sense to do something like: class Person scope :grouped_counts, group(:name).count end But this doesn't work. I get this error:

I am building a Rails 4 app and am using Foreman for my dev setup with a Procfile and .env file for configuration. When I set an ENV variable in the .env file, it is correctly picked up by my app. In this case I am setting some ENV options for Paperclip in an initializer. The problem surfaces when I go to change the value of the ENV variables. In the console, if I type ENV["MY_VAR"], it shows the new value. However, the value that was used in my initializer, which

In this case there may be three records with the same style, I want this named_scope to only give unique values of title. So ["style 1", "style 1", "style 1"] isn't possible, it'll force itself to give ["style 1", "some style 2", "maybe another 3"] i think group may do it and I'm using that for now. If anyone has
