This call is responsible for isolating the controllers, models, routes and other things into their own namespace, away from similar components inside hte application. Without this, there is a possibility that the engine's components could "leak" into the application, causing unwanted disruption, or that important engine components could be overriden by similarly named things within the application. +The +isolate_namespace+ method here deserves special notice.

Without this, there is a possibility that the engine's components could "leak" into the application, causing unwanted disruption, or that important engine components could be overriden by similarly named things within the application. One of the examples of such conflicts are helpers. Without calling +isolate_namespace+, engine's helpers would be included in application's controllers. NOTE: It is *highly* recommended that the +isolate_namespace+ line be left within the +Engine+ class definition. Without it, classes generated in an engine *may* conflict with an application. |
