ruby-on-rails-4.1

问题 Normally I wouldn't store objects in a Rails session but I'm using a library that requires this. I've run into a very strange issue where a stored object appears as a String after redirect. To reproduce I've created a sample Rails 4.1 app $ rails new session-test Added a test controller: class HomeController < ApplicationController def index logger.debug "session[:customer]: #{session[:customer]}" logger.debug "session[:customer].name: #{session[:customer].name}" end def from Struct.new

问题 I've a .env file in my root folder in production. This file defines SECRET_KEY_BASE which is used in config/secrets.yml . The problem is that I can't manage to load my .env file before my config/secrets.yml . I've tried using the dotenv gem without success. Any idea on how todo this in production?

问题 I am a bit new to Ruby and am writing a program from scratch... I'm getting an error and I can't figure out where it is coming from. I've spent over an hour and i'm sure it's something stupidly simple. I have other similar pages that work fine, but there's some issue with the instance variable. It's almost an identical problem as the link provided. Here's my error: Showing C:/Users/kevin/Desktop/ruby_test/sites/simple_cms/app/views/sections/_form.html.erb where line #4 raised: undefined

问题 So I'm using this social gem but for some reason I'm getting the following error: wrong number of arguments (1 for 0) and this is the line of code that's causing the error: <%= tweet_button(via: "peterc", url: "http://news.ycombinator.com", :text => "AWESOME.") %> Not sure what I'm doing wrong, I've read the Documentation on the gem quite thoroughly.
