store rails views on database instead of filesystem

An ActionView::Resolver implementation to store rails views (layouts, templates and partials) on database. Simply put: what you can do with views on filesystem, can be done on database.
NOTE: at the moment, only ActiveRecord is supported, I've planned to add more ORMs (see Todo). If you can't wait, adding other ORMs should be very trivial.
Add the following line to Gemfile:
Your model should have the following fields:
they're what the rails' Resolver API needs to lookup templates.
A simple macro in model will activate your new Resolver. You can use a dedicated model to manage all the views in your app, or just for specific needs (ex: you want a custom template for some static pages, the other views will be fetched from filesystem).
class TemplateStorage < ActiveRecord::Base store_templates end
To add Panoramic::Resolver in controller, depending on your needs, you may choose:
NOTE: the above methods are both class and instance methods.
class SomeController < ApplicationController prepend_view_path TemplateStorage.resolver
def index # as you may already know, rails will serve 'some/index' template by default, but it doesn't care where it is stored. end
def show # explicit render render :template => 'custom_template' end
def custom_template # use another model to fetch templates prepend_view_path AnotherModel.resolver end end
And let's say you want to use database template resolving in all your controllers, but want to use panoramic only for certain paths (prefixed with X) you can use
class ApplicationController < ActionController::Base prepend_view_path TemplateStorage.resolver(:only => 'use_this_prefix_only') end
This helps reducing the number of database requests, if Rails for example tries to look for layouts per controller.
class MyEmail < ActionMailer::Base prepend_view_path TemplateStorage.resolver

spec/dummy/, you'll find a dummy rails app I used to make tests ;-)
Enter Panoramic gem path, run
bundle installto install development and test dependencies, then
Fork, make your changes, then send a pull request.
The main idea was heavily inspired from José Valim's awesome book Crafting Rails Applications. It helped me to better understand some Rails internals.
