Angular question about mixing in directive behaviors

Let's say I've declared three class-restricted directives "am-wat", "am-foo", and "am-bar", that each augment the attached element with some behavior, e.g.:

<div am-wat="some data" am-foo="other data" am-bar="lol">
  Yadda yadda yadda

Is there a way to write a directive that mixes in the behavior of the three directives, e.g.:

Basic/obvious QP limitation

Limitation regarding hrefs on non-route-driven controllers

TL;DR: lack of information about default values on non-route-driven controllers might force us to make href's overly verbose in some cases, or possible make us punt on non-route-driven-controller query params.

Scenario: ->

query params HOME STRETCH

Aside from the few bugs that I know I need to fix about query params, there are a few remaining issues that I need help with, driven by real legit use cases from folk I've been talking to.

Also, if you haven't been keeping up, I have a PR in that added the model-dependent state stuff I talked about at EmberConf to query params, which impacts the way query params are reset/restored between changing routes/models.


TL;DR generate changelists of app state mutations that can be used in cases where it's necessary to be able to predict what will happen when some action is invoked, e.g. linking into another route.

I've had this zany idea floating around that I just wanted to share that's probably extremely over-engineered to over-solve problems in the routing domain, but I figured I'd share it and see if any lightbulbs go off.

So in routing land, one of the harder things to calculate is a link's href; we have have to use the provided destination rout and the contexts to provide to basically ask "if this transition were to take place, what URL would you end up with?". This has led to some interesting code with query params, particularly with model dep state, where we have to say "given this destination route, these contexts, this list of explicitly provided query params, please fill sensible default values for unspecified query params and tell me what the final URL is going to be".

Particularly in nailing down these last

      • any other QPs on target route get automatically filled in based on model-dependent state
