hi, i'm at the point in my app where i'm ready to release it into the wild (in this case my internal work intranet, not on the internet), and the only thing holding it up is the implementation of a some sort of login/authentication system. i know there are a bunch of login system generators and plugins that are available, but I'm not sure which one to use. the setup of the application is extremely simple; basically a list of products with some detail information that i (the admin) updates, and the rest of the world only has read-only access. no shopping carts, no designer/author/publisher paradigms-- you either can change the data or you can't. for such a simple case, should I even bother with a prefab solution, and just write one myself? or is that a recipe for disaster (keeping in mind a looming deadline and limited, but growing, ruby/rails skills)? if a home-grown solution is not the answer, which of the available pre-made modules would be best for this situation? thanks in advance for any insight.

If you want to use a prefab one I think Login Engine is the one for you. http://rails-engines.rubyforge.org/wiki/wiki.pl?LoginEngine I haven't used it but it seems like the right one for simple cases. It is an engine so it is easy to upgrade. - Peter

It is an engine so it is easy to upgrade. Peter, Thanks for the heads up on the LoginEngine, it looks like a good starting point. Although, I am running into problems getting it up and running. I'm following the instructions for installing the Engine plugin at http://rails- engines.rubyforge.org/rdoc/engines/ but when i get to: -> cd vendor/plugins/login-engine -> rake rdoc I get: -->> rake aborted! -->> Don't know how to build task 'rdoc' So, skipping that, I move onto the next step, -> cd vendor/plugins/login-engine -> rake db_schema_import I get: -->> No such file to load -- db/schema.rb however, schema.rb is clearly in the db/ folder. Neither command worked, so I don't have a functional LoginEngine. I know you mentioned you don't have any experience with this engine... anyone else have any thoughts on what I may be doing wrong? I'm on WinXP/Rails 1.0RC3 Thanks

2005/11/29, dave davidson <firstname.lastname@example.org>: > I'm on WinXP/Rails 1.0RC3 rdoc through rake does not work on Windows. Your other problem though... Are you in the right folder ? You need to cd vendor\plugins\login_engine before you can run those Rake tasks. Hope that helps !

I suspect the documentation you are refering to is the Engines README, which describes only an example engine rather than anything real, whereas you might make better progress looking at the actual LoginEngine documentation: http://rails-engines.rubyforge.org/rdoc/login_engine/ I guess I should make this clear: 'Engines' are a means for distributing code, *exactly* like plugins (in fact they *are* plugins). The LoginEngine is just one possible engine. To install the LoginEngine, install the Engines plugin and the LoginEngine in the same way you would any other plugin, using the 'script/plugin' install command. Then follow the instructions for the specific engines you are working with... - james

Okie doke, here goes: A plugin is an encapsulated bit of logic, probably (but certainly not limited to) including modules to enhance ActiveRecord objects, or application helpers An 'engine' is a plugin which also can include views, full controllers, model objects, schema and migration data - almost anything you might want to put in a normal Rails application. You can't include things like views and migrations in normal rails plugins and have them 'just work' The actual 'Engines' plugin is the plugin which enhances your normal Rails application such that the extra views/controllers/migrations/etc in your plugins get intelligently mixed in to your application - i.e. it contains the code that makes things 'just work'. The LoginEngine/UserEngine/WikiEngine/WhateverEngine are *examples* of plugins which takes advantage of the features provided by the Engines plugin... therefore we (I) call them 'engines'. I'm aware of this kind of confusion where one might believe that Engines == LoginEngine, and that if you're using Engines at all then you MUST be using the LoginEngine, which is only as true as saying that the Generators == SHLG. 'Engines' are a way of sharing code. The 'LoginEngine' is an example - an 'instance' if you like OO parlance. If you have a chunk of code in the form of controllers/models/views that you find yourself reusing in multiple projects, you might consider turning them into an 'engine'-style plugin in the same manner you might think about making them into a generator (I would argue that engines (and in fact all plugins) are much easier to build and maintain than generators, though). So, to recap, you've got: 1. normal plugins... then 2. the Engines plugin, which *is* a normal plugin that uses the regular plugin mechanism to enhance Rails so you can then use and develop your own 3. 'Engines', i.e. the LoginEngine or WikiEngine, which are just like plugins except they can provide views, etc, AND they depend on the 'Engines plugin' to blend their 'advanced' features into your application. Does that make more sense? - james

Yes, thanks!

James, Maybe post this explaination on your engines wiki for future reference? It is a nice introduction. Perhaps it could be expanded over time with more full details and explaination. Peter
