Is it possible to pass params to #block-slot for use in #yield-slot? about ember-block-slots HOT 2 CLOSED

Hi @sglanzer, that makes sense. I had a hunch that a contextual component was probably the way to go.

Though it's not in the simple example I provided above, I was attempting to render a data-key attribute (unique id) per row. I ended up moving my iteration from the yield-slot to within the block-slot and using a contextual component as a wrapper, passing the data-key to that component.

Thanks for your help 👍

Hey @mnoble01 - no, the direction of block parameters is from the yield to the block.

Since the consumer controls the block and the yield is effectively just a placeholder what's the use case for passing parameters back to the yield?

I believe what you want in this case is a contextual component, there is an example here http://ciena-blueplanet.github.io/ember-block-slots/ in the purple section

  {{#yield-slot 'contextual' (block-params
    (hash role=(component 'role-component'))
    title
  )}}
    {{yield}}
  {{/yield-slot}}

  {{#block-slot 'contextual' as |componentHash title|}}
    {{#componentHash.role role='row'}}
      {{title}}
    {{/componentHash.role}}
  {{/block-slot}}

Hopefully that helps answer the question
