Instances API Endpoint¶

Results¶

Each instance data structure includes the following fields:

• id: Database ID for this instance. (integer)

• type: Data type for this instance. (choice)

  • instance: instance

• url: URL for this instance. (string)
• related: Data structure with URLs of related resources. (object)
• uuid: Unique identifier for the instance (string)
• hostname: Hostname for this instance. (string)
• created: Timestamp when this instance was created. (datetime)
• modified: Timestamp when this instance was last modified. (datetime)
• version: Version of this instance (string)
• capacity: Total capacity for this instance. (integer)
• consumed_capacity: Capacity this instance has consumed. (field)
• percent_capacity_remaining: Percentage of remaining capacity for this instance. (field)
• jobs_running: Number of jobs running on this instance. (field)

Sorting¶

To specify that instances are returned in a particular order, use the order_by query string parameter on the GET request.

?order_by=name

Prefix the field name with a dash - to sort in reverse:

?order_by=-name

Multiple sorting fields may be specified by separating the field names with a comma ,:

?order_by=name,some_other_field

Pagination¶

Use the page_size query string parameter to change the number of results returned for each request. Use the page query string parameter to retrieve a particular page of results.

?page_size=100&page=2

The previous and next links returned with the results will set these query string parameters automatically.

Searching¶

Use the search query string parameter to perform a case-insensitive search within all designated text fields of a model.

?search=findme

Search across related fields (added in AWX 1.4 / Ansible Tower 3.1):

?related__search=findme

Filtering¶

Any additional query string parameters may be used to filter the list of results returned to those matching a given value. Only fields and relations that exist in the database may be used for filtering. Any special characters in the specified value should be URL-encoded. For example:

?field=value%20xyz

Fields may also span relations, only for fields and relationships defined in the database:

?other__field=value

To exclude results matching certain criteria, prefix the field parameter with not__:

?not__field=value

By default, all query string filters are AND’ed together, so only the results matching all filters will be returned (added in AWX 1.4). To combine results matching any one of multiple criteria, prefix each query string parameter with or__:

?or__field=value&or__field=othervalue
?or__not__field=value&or__field=othervalue

The default AND filtering applies all filters simultaneously to each related object being filtered across database relationships (added in Ansible Tower 1.4.5). The chain filter instead applies filters separately for each related object. To use, prefix the query string parameter with chain__:

?chain__related__field=value&chain__related__field2=othervalue
?chain__not__related__field=value&chain__related__field2=othervalue

If the first query above were written as ?related__field=value&related__field2=othervalue, it would return only the primary objects where the same related object satisfied both conditions. As written using the chain filter, it would return the intersection of primary objects matching each condition.

Field lookups may also be used for more advanced queries, by appending the lookup to the field name:

?field__lookup=value

The following field lookups are supported:

• exact: Exact match (default lookup if not specified).
• iexact: Case-insensitive version of exact.
• contains: Field contains value.
• icontains: Case-insensitive version of contains.
• startswith: Field starts with value.
• istartswith: Case-insensitive version of startswith.
• endswith: Field ends with value.
• iendswith: Case-insensitive version of endswith.
• regex: Field matches the given regular expression.
• iregex: Case-insensitive version of regex.
• gt: Greater than comparison.
• gte: Greater than or equal to comparison.
• lt: Less than comparison.
• lte: Less than or equal to comparison.
• isnull: Check whether the given field or related object is null; expects a boolean value.
• in: Check whether the given field’s value is present in the list provided; expects a list of items.

Boolean values may be specified as True or 1 for true, False or 0 for false (both case-insensitive).

Null values may be specified as None or Null (both case-insensitive), though it is preferred to use the isnull lookup to explicitly check for null values.

Lists (for the in lookup) may be specified as a comma-separated list of values.

Filtering based on the requesting user’s level of access by query string parameter (added in Ansible Tower 3.1).

• role_level: Level of role to filter on, such as admin_role
