This code snippet retains the only value of a multi-valued type field which can either be an array of objects or a set of values. This snippet is useful when you know that the array has only one value and hence by applying the first or last methods you can retain it.
Use the first/last filter to get the only object of the field and access the specific field for the required value.
{# Apply the first/last filter to the array of objects. Upon that apply the field filter #}
{{ issue.fields["<Multi-valued field>"] | <filter> | field("<Value>") }} |
| Placeholder | Description | Example |
|---|---|---|
<Multi-value field> | Name of the multi-valued field | Technical tasks |
<filter> | Filter to be applied | first |
<Value> | Value to fetch | value |
Since you already know the collection of objects has only one value you could use the |
The output of the code snippet is the only value of a multi-valued field which you could use in a template, for example to:
Set a field in one of the Set field value post-functions or the Create issue post-function under the Set fields of new issue section. Examples:
{{ issue.fields.comment.comments | last | field("author.accountId") }} |
Name of the issue link type of the only linked issue to the current issue
{{ issue.fields.issuelinks | first | field("type.name") }} |
Send an email to the first user of a Multi-user picker field in the Email issue post-function
{{ issue.fields["Multi-user picker"] | first | field("accountId") }} |
