collection option in .partial

[Oleg Slobodskoi]

hi,

I am reading renderPartial private method from view.js and don't get
how it supposed to work.

if I pass array as second argument partial('view', [{a:1}, {a:2}]) it
should render the partial "view" 2 times and pass first and second
array element.

your jade example seems to work so, but in my implementation I am not
getting array elements, instead the whole res thing and the only place
I can see needed array elements is res.view.

Need help :)

yeah with a collection all it does is iterate and keep calling render()

so the only way to access elements is res.view (my example)?

res.partial('pet', ['tobi', 'loki']) would render the template twice with the "pet" local var first set to "tobi", then "loki"

but how the partial view should know its name. you are using a fancy
method to resolve the key from view path: partial.resolveObjectName.

you can use the "as" option, by default it resolves the name, why do you need to know the name dynamically?

lets take an example:

//main.html
<div id="main">{{partial('partial.html'), [{a:1}, {a:2}] }}</div>

//partial.html
<div id="partial">${a}</div>

// expected output
<div id="main">
<div id="partial">1</div>
<div id="partial">2</div>
</div>


this is how I expect it to work ... but it seems I mistunderstand
something ...

[Oleg Slobodskoi]

ups little mistake


//main.html
<div id="main">{{partial( [{a:1}, {a:2}]), 'partial.html'}}</div>

//partial.html
<div id="partial">${a}</div>
// expected output
<div id="main">
<div id="partial">1</div>
<div id="partial">2</div>
</div>

no, the object keys are not expanded as locals, those two objects become "the" object passed. so partial.a would be 1 the first time, 2 the second time

and this means I would have to know the name of my partial to access
the data ... so "partial.a" ... this is not hard in this example, but
considering what the fancy method "partial.resolveObjectName" can
do ... I actually can't access it just directly ...

[TJ Holowaychuk]

partial('something', { as: 'user', collection: [user, user2, user3] })

or

partial('user', [user, user2, user3])

usually best just to not name things poorly, but it can be done with the options, it's just much more  verbose.

if you want to key them, just iterate yourself and use res.partial('foo', { a: 'something' }), explicitly passing the locals

--

[Oleg Slobodskoi]

so I have explicitely name the key the data will be attached to.

I suppose its because partials have parent data as a root key:value
and you are trying to separate them?

[TJ Holowaychuk]

partials are primarily focused to a single object, which is how we can cut down on the verbosity a bit by assuming things. if you just simply want to render a template, use res.render() with layout: false if needed

ok, I just saw into documentation, this ".as" thing is not in.
