Edit: Shortened and clarified the problem.

What's the most practical way to achieve the following in my Meteor app using Iron Router:

• Condition A - show template A
• Condition B - show template B
• otherwise - show template C

for a single URL, so that a user cannot directly enter "/url-a" or "/url-b" or "url-c" to select the view/template explicitly.

回答1:

Given the limited information you've provided, I can't think of anything shorter than the following logic in your route:

if ( A ) this.render('templateA');
else if ( B ) this.render('templateB');
else this.render('templateC');

This assumes that you have a route with a layout and you're rendering a template into that layout.

But given this answer is so trivial I suspect you're asking a different question altogether.
