问题 I'm new to Rspec and trying to set up a test for a User Profile. Profile belongs_to User. Now, I have an API integration with a third party site that works through the User Model, but some of the information for that API link is contained in Profile, so I have an "after_update" filter on Profile that tells the parent user to save, which triggers an update of the API.

问题 Is there a way to configure the isolate_namespace method to not use prefixed table names? class Engine < ::Rails::Engine isolate_namespace MyEngine end Additionally, an isolated engine will set its name according to namespace, so MyEngine::Engine.engine_name will be “my_engine”. It will also set MyEngine.table_name_prefix to “my_engine_”, changing the MyEngine::Article model to use the my_engine_articles table.Isolated Engine Docs When designing a prototype I ran into an issue where I need

问题 To get the image path in Controller I use the following method: class AssetsController < ApplicationController def download(image_file_name) path = Rails.root.join("public", "images", image_file_name).to_s send_file(path, ...) end end Is there a better method to find the path ? 回答1: ActionController::Base.helpers.asset_path('missing_file.jpg') Access Asset Path from Rails Controller 回答2: Not sure if this was added as early as Rails 3, but is definitely working in Rails 3.1.

问题 I'm trying to write out tests for a controller of mine that takes in requests from external services. So far this is my test: describe ApplyController do context 'when valid' do let(:parameters) do file = File.join File.dirname(__FILE__), '..', 'samples', 'Indeed.json' JSON.parse(File.read file) end let(:signature) { 'GC02UVj0d4bqa5peNFHdPQAZ2BI=' } subject(:response) { post :indeed, parameters, 'X-Indeed-Signature' => signature } it 'returns 200 ok if Request is valid' do expect(response

问题 I've read a pile of other related questions... nothing really seems to answer the question I have. My application will integrate with several different third party sites. (ebay, paypal, google, amazon...) It is a product management system and it pushes products all over the place... Of course since it interacts with all these sites, it needs usernames, passwords, tokens.. ect..
