How to require a ruby file from another directory

由 蹲街弑〆低调 提交于 2019-11-28 04:57:14
I am trying to require a rake file that I have created inside another file I have. These two files are inside two different directories. I have require at the top of my first file with the name of the second file inside the quotes after the require. It is telling me that it can't load such file. Does that mean because its in different directory it can't find it? I tried sticking in the full path to the second file but it still can't load the file. Does anyone know how I can load the second file into the first? Thanks in advance require will search for files in only a set of locations referred

Rendering JSON in controller

由 爱⌒轻易说出口 提交于 2019-11-28 02:58:39
I was reading a book and in a chapter about Controllers when it talks about rendering stuff, for JSON it has an example like this but doesn't go in to details so I couldn't figure out the bigger picture that this example fits in: render :json => @projects, :include => tasks And also some example with JSONP using it with callback functions: render :json => @record, :callback => 'updateRecordDisplay' Can someone explain these? You'll normally be returning JSON either because: A) You are building part / all of your application as a Single Page Application (SPA) and you need your client-side

How to initialize an ActiveRecord with values in Rails?

由 微笑、不失礼 提交于 2019-11-27 23:18:29
问题 In plain java I'd use: public User(String name, String email) { this.name = name; this.email = f(email); this.admin = false; } However, I couldn't find a simple standard way to do in rails (3.2.3), with ActiveRecords. 1. override initialize def initialize(attributes = {}, options = {}) @name = attributes[:name] @email = f(attributes[:email]) @admin = false end but it might be missed when creating a record from the DB 2. using the after_initialize callback by overriding it: def after

Reserved names with ActiveRecord models

由 心已入冬 提交于 2019-11-27 20:21:50
I take naming pretty seriously, so I think pretty hard about good names for my ActiveRecord models. However, I frequently come up with a name and it has some conflict with a reserved name, either in the database or Ruby or Rails. Model or field names like set or group .
