Warning!

It's better to check repo https://github.com/ciena-blueplanet/ember-spread - goals which we were leaded by whyle creating this helper totally covered with that addon, and it's definitely better that our approach. So code saved just for really hard cases (but think more than twice before starting use it )

ember-render-helper

Render helper for Ember.js ( Allow render components dynamically )

##Motivation Sometimes we need to render component by name, which stores at some property. For such cases there are several workarounds.

You can read next links:

http://discuss.emberjs.com/t/programmatically-rendering-ember-components/6986

http://stackoverflow.com/questions/25946805/how-to-dynamically-load-ember-components-by-name-in-a-template

https://stackoverflow.com/questions/18972202/how-can-i-invoke-an-ember-component-dynamically-via-a-variable

etc.

##Solutions Of course at newer Ember component helper But current version and it's documentation doesn't describe how to pass arguments/paraments. Also it is not available for older versions of Ember. So here is another one 'bicycle'

##Examples All this examples describe at file comments. Here i just duplicate them

{{render-component 'image-component' src="" class="image"}}

{{#render-component 'btn-component' action="addSection"}}

{{#render-component componentName _param='btn-component' action="addSection"}}

or

{{#render-component 'btn-component' action="addSection"}}
 Add section
{{/render-component}}

or even

{{#render-component 'render-component' _param='btn-component' action="addSection"}}
  Add section
{{/render-component}}

You also can use ___params to define all properties via hash like instead of

{{render-component 'pluralize-component' count=ungrouped.content.meta.total single="Object"}}

you can use

{{render-component 'pluralize-component' ___params=hash}}

and hash is

hash = { count:ungrouped.content.meta.total, single:"Object"}

For cases when we need pass into component not only attributes but param too When we need this? for example you want to render

{{componentName paramName someOption=someOptionValue}}

You can do

{{#render-component 'componentName' someOption=someOptionValue}}

BUT! You can't do ( you can't pass more than one argument into component )

{{#render-component 'componentName' paramName someOption=someOptionValue}}

so for such cases you can use '_param' ( at line param or at hash property )

{{#render-component 'componentName' _param=paramName someOption=someOptionValue}}

or

{{#render-component 'componentName' __params=paramsHash}}

where paramsHash is

paramsHash = { _param:paramName, someOption=someOptionValue }

##Tests Sadly for me, but right now there are no tests for helper ( yep, I know it's not good ). But I hope to fix this in future.
