Great series. I’ve seen my love for OO programming take a hit recently when realizing what I’m programming are just tasks or “jobs that need doing.” In agreement with your controller-less concept, I’m finding that better flexibility is achieved by wrapping every Task in its own interface. In these implementations, the very notion of an “object” becomes really just the infrastructure needed to perform the Task– a layer that declares and manages dependencies of the task. I’m left with only datastructures and functions. Feels a bit remedial, honestly and indicative of what’s denounced as anemic domain models. What about DDD? DSLs?

That’s because they’re not hierarchical. Jeremy calls them Matryoshka dolls, which is closer to the reality, but behaviors can fork and call out to other behaviors, so “graph” is probably more realistic. This is a gross simplification (and very old): http://www.infoq.com/news/2009/04/fubu-mvc

Good explanation. I don’t think any of the articles I’ve read about behaviours show a nice hierarchical diagram – I think it would clarify the concept a lot.

John, that will be covered in part #10 (the number may be subject to change). But to answer your question about view logic: We do not have separate views (although you could do it that way but it may end up being too much extra work depending on the circumstances). We try to avoid direct logic (if statements) in views, though we cheat in a few places. We’ll try to deal with it by optionally rendering/not rendering partials, by dealing with it in our HtmlTags for InputFor() (determining whether it’s editable, read-only, or invisible for this user), etc.

We may also have something like:

x.FirstName).OnlyForPrivilege(“foo”) %>

We try to make our privileges (the things that are securable in the app) conventionally names and flowing from our domain, our controllers, our models, etc, but we do have a few one-off privileges for special functionality in our app.

Then we have roles that you map users to and map privileges to the roles and the users get those privileges.

Chad, your FubuCore series were awesome, and now these ones, very exciting stuff.
If possible can you cover how you guys deal with views that change based on user role, eg:
UserA can see some data on /products/view/1234 but UserB is not allowed to see it(and this may have implications on how the HTML is structured). I’m interested to find out if you guys create a View per role or do the logic on the View itself.

Can’t wait for the next one!

This stuff sounds pretty nice, Chad. I, too, have noticed that for some reason MVC controllers are exempt from SRP in too many developer’s minds.
