with (options) Stringpublic
Use the {{with}} helper when you want to alias a property to a new name. This is helpful for semantic clarity as it allows you to retain default scope or to reference a property from another {{with}} block.
If the aliased property is "falsey", for example: false, undefined null, "", 0, NaN or an empty array, the block will not be rendered.
1 2 3 4 5 6 7 8 9 | {{! Will only render if user.posts contains items}}{{#with user.posts as |blogPosts|}} <div class="notice"> There are {{blogPosts.length}} blog posts written by {{user.name}}. </div> {{#each blogPosts as |post|}} <li>{{post.title}}</li> {{/each}}{{/with}} |
Without the as operator, it would be impossible to reference user.name in the example above.
NOTE: The alias should not reuse a name from the bound property path. For example: {{#with foo.bar as |foo|}} is not supported because it attempts to alias using the first part of the property path, foo. Instead, use {{#with foo.bar as |baz|}}.
