Deprecation Guide for {{hasBlock}} and {{hasBlockParams}}

until: 4.0.0
id: has-block-and-has-block-params

{{hasBlock}}

The {{hasBlock}} property is true if the component was given a default block, and false otherwise. To transition away from it, you can use the (has-block) helper instead.

{{hasBlock}}

{{! becomes }}
{{has-block}}

Unlike {{hasBlock}}, the (has-block) helper must be called, so in nested positions you will need to add parentheses around it:

{{#if hasBlock}}

{{/if}}


{{! becomes }}
{{#if (has-block)}}

{{/if}}

You may optionally pass a name to (has-block), the name of the block to check. The name corresponding to the block that {{hasBlock}} represents is "default". Calling (has-block) without any arguments is equivalent to calling (has-block "default").

{{hasBlockParams}}

The {{hasBlockParams}} property is true if the component was given a default block that accepts block params, and false otherwise. To transition away from it, you can use the (has-block-params) helper instead.

{{hasBlockParams}}

{{! becomes }}
{{has-block-params}}

Unlike {{hasBlockParams}}, the (has-block-params) helper must be called, so in nested positions you will need to add parentheses around it:

{{#if hasBlockParams}}

{{/if}}


{{! becomes }}
{{#if (has-block-params)}}

{{/if}}

You may optionally pass a name to (has-block-params), the name of the block to check. The name corresponding to the block that {{hasBlockParams}} represents is "default". Calling (has-block-params) without any arguments is equivalent to calling (has-block-params "default").
