    ruby-on-rails-3 static assets rails-engines
    I’m building an engine I’ve bundled as a gem (gmaps4rails). I copied the /public of my engine in the /public of my rails app.Everything works fine in development but fails to work in production: it appears static assets (of my engine & my main app) aren’t found.The logs tell the following (just an abstract):Started GET “/javascripts/application.js?1286294679” for 127.0.0.1 at Wed Nov 24 00:22:20 +0100 2010ActionController::RoutingError (No route matches “/javascripts/application.js”):Rendere

    I assume that if you mount an app in a main rails or use a rails engine. If any of the sub-apps fail/crash than that means the main app and all the sub-app fail/crash. Does anyone know this for sure? I am wondering if I am building a system if I should separate my architecture into multiple standalone application and instances or build Engine/mountable apps instead of a larger app. The worry is what would happen if part of the app ecosystem goes don’t how does it effect the rest of the applicati

    ruby-on-rails facebook omniauth rails-engines
    I’m developing a mountable engine (called SimpleUser) which uses Devise, OmniAuth and OmniAuth-Facebook. First I made a test app with the gems about and every worked fine. Next, I started building the engine from scratch, using the code of the test app as an example.Everything is almost done, except for the connection with Facebook (it uses the Javascript popup). When I click in “log in” the FB popup is displayed, I grant the app, it redirects to the route specified (see routes), but throws this

    I’ve spent the last 2 days reading everything I could find on blogs, in books, in other gems’ source, and on SO and I can’t for the life of me figure this out. Admittedly I’m new to writing Ruby gems, Rails engines, and am not entirely familiar with all the RSpec view methods (but I’m learning as much as I can access).I’ve made my project public on Github (albeit in the early stages, but this is based on some markup I’ve been reusing on recent projects that I’m slowly trying to pull into this ge

    I made a mountable engine.

    This is more for experimentation – I am aware that I can do this with –full but I wanted the functionality of namespacing in the app to avoid conflicts The idea is to have a main app – which handles authentication, common items, admin screens etc Then creating engines to add further functionality likecrm cms blog wiki forum etc These engines I can pick and choose as I need for whatever kind of app I am building. Is this possible?Is it just the case of applying both –mountable and –full opt

    A lot has been written about engine development, and using a dummy app for testing.In our case we’re developing an engine that is not a stand-alone entity, but has dependencies on a real Rails 3 application. We still want this code to live in an engine, and not become part of the app, because the engine’s job is to import data from a legacy system that has its own tables and model mappings, and we want to eventually remove it again.The data mappings between the old legacy tables and the new sche

    I have created a simple Rails Engine to provide some general functionality(photo gallery) to an application. I want to be able to override the standard _header partial so that the menu for the gallery matches that of my main application. In my header view I call a helper that is part of application_helpers (main app), but I keep getting “undefined method” errors. From what I can tell the main app application_helpers are not being included (obviously) when I override the engines application la

The problem occurs when I use it in a model (for example, in callbacks or even simple instance methods).#inside the vehicle model def add_enginesEngine.all.each do |ngin|…endI get the error: NoMethodError: undefined method ‘all’ for #<Some_mounted_engine_name:0x00000103b48828>I search the web, but I do not see Engine as a reserved word. Note that we use mounted engines in our app.

Inside the create action of the sales controller I do a little bit of data processing and try to instantiate a Sale object. Instead of creating an object from a model, I get a NoMethodError exception for a delete method th
