# sortify

Setting sortify: true creates a parallel version of the field that is more intuitive for sorting purposes. This new, additional property's key will be the string field's name, appended with Sortified. Its value will be fully lowercase and have all punctuation removed. Apostrophe will automatically use it if a request is made to sort on the original field.

For instance, if your field's name is lastName and you set sortify: true, lastNameSortified will automatically be created and used when sorting on the lastName field. This provides case-insensitive sorting that also ignores punctuation differences.

NOTE

If you add sortify: true to an existing field, existing objects will get the sortified version of the field:

  • on the next deployment via the apostrophe-migrations:migrate command line task,
  • when the individual Apostrophe documents are saved, or
  • at the next startup when in development.

Migrations like this only need to be run once because on future updates or inserts of a document the sortified property is automatically set.

# Use in templates

The Nunjucks nl2br (opens new window) tag can help print textarea strings with line breaks.

<h2>{{ data.piece.dogName }}</h2>
<p>
  {{ data.piece.biography | striptags(true) | escape | nl2br }}
</p>
