At the moment I have this in my template:
* **WAY 1**
<template is="dom-if"
if="{{_showCancel(userData.generic.id,info.userId,info._children.gigId.userId,info.accepted,info.cancelled,info.paymentTerms)}}">
And then this in my element:
_showCancel: function(viewerUserId,offerUserId,gigUserId, accepted,
cancel, paymentTerms) {
// Offer needs to be accepted and NOT cancelled
if (!info.accepted || info.cancelled) return false;
// Gig owner can ALWAYS cancel an offer
if (viewerUserId == gigUserId ) return true;
// Offer maker can only cancel if the gig involved pre-payment
if (viewerUserId == offerUserId && paymentTerms != 'on-day') return
true;
return false;
},
Do I have just too many parameters to this function?
* **WAY 2**
Should I just have something like this instead:
<template is="dom-if" if="{{_showCancel(userData, info)}}">
* **WAY 3**
Although I would want to check if their sub-properties change too... so I
would need:
<template is="dom-if" if="{{_showCancel(userData, info, userData.*,
info.*)}}">
* **WAY 4**
But then again I probably should just look for the properties and use the
`value` property like so:
<template is="dom-if" if="{{_showCancel(userData.*, info.*)}}">
And then the function would be:
_showCancel: function(userDataObs, infoObs) {
var userData = userDataObs.value;
var info = infoObs.value;
if( !userData || !info) return;
...
Questions:
* Do you see any fundamental mistakes with ways 1 to 4?
* Is WAY 1 really the best way to go about it? (it feels like it right now)
* Is WAY 3 an acceptable pattern?
