The module awx.awx.inventory is failing to create constructed inventories - Edge case uncaught

Bug Summary

Edge Case

hello, I believe there is an edge case uncaught with the module awx.awx.inventory when attempting to add an input_inventories which causes the error message below:

“msg”: “The requested object could not be found at /api/v2/constructed_inventories/24/input_inventories/” 

It's due to the fact the URL built is wrong when adding an associations of type input_inventories to a resource constructed_inventory

Problematic Code Snippets

I believe the problematic code that caused the URL to be built wrong and cause the 404 to happen is combination of the snippets below in awx/awx_collection/plugins/module_utils/controller_api.py

# awx/awx_collection/plugins/module_utils/controller_api.py
def create_if_needed(self, existing_item, new_item, endpoint, on_create=None, auto_exit=True, item_type='unknown', associations=None):

...

            if response['status_code'] in [200, 201]:
                self.json_output['name'] = 'unknown'
                for key in ('name', 'username', 'identifier', 'hostname'):
                    if key in response['json']:
                        self.json_output['name'] = response['json'][key]
                self.json_output['id'] = response['json']['id']
                self.json_output['changed'] = True
                item_url = response['json']['url']
            else:
                if 'json' in response and '__all__' in response['json']:
                    self.fail_json(msg="Unable to create {0} {1}: {2}".format(item_type, item_name, response['json']['__all__'][0]))
                elif 'json' in response:
                    self.fail_json(msg="Unable to create {0} {1}: {2}".format(item_type, item_name, response['json']))
                else:
                    self.fail_json(msg="Unable to create {0} {1}: {2}".format(item_type, item_name, response['status_code']))

        # Process any associations with this item
        if associations is not None:
            for association_type in associations:
                sub_endpoint = '{0}{1}/'.format(item_url, association_type)
                self.modify_associations(sub_endpoint, associations[association_type])

and

# awx/awx_collection/plugins/module_utils/controller_api.py
    def modify_associations(self, association_endpoint, new_association_list):
        # if we got None instead of [] we are not modifying the association_list
        if new_association_list is None:
            return

        # First get the existing associations
        response = self.get_all_endpoint(association_endpoint)
        existing_associated_ids = [association['id'] for association in response['json']['results']]

Explanation

In ControllerAPIModule.create_if_needed(self) (code ref link)

The url and the body for the POST call

'https://<REDACTED>.com/api/v2/inventories/'
'{"name": "REDACTED", "organization": 2, "kind": "constructed", "host_filter": null, "input_inventories": [2]}'

will yield the successful response

response['json']['url'] = /api/v2/constructed_inventories/<id>

this is then stored in item_url which used to build the association sub_endpoint (code ref link)

`sub_endpoint=/api/v2/constructed_inventories//input_inventories

        if associations is not None:
            for association_type in associations:
                sub_endpoint = '{0}{1}/'.format(item_url, association_type)
                self.modify_associations(sub_endpoint, associations[association_type])

then later on, when self.get_all_endpoint(association_endpoint) which calls response = self.get_endpoint(endpoint, *args, **kwargs) with this /api/v2/constructed_inventories/<id>/input_inventories it will cause the 404 as that enpoint isn't defined.

 def modify_associations(self, association_endpoint, new_association_list):
        # if we got None instead of [] we are not modifying the association_list
        if new_association_list is None:
            return

        # First get the existing associations
        response = self.get_all_endpoint(association_endpoint)
        existing_associated_ids = [association['id'] for association in response['json']['results']]

Hope this makes sense. Please let me know what the action items are from this, or suggested course of action I can take.

Steps to reproduce

• ANSIBLE_KEEP_REMOTE_FILES=1 ansible localhost -m awx.awx.inventory -a '<module_args>' -vvv
• cd /path/to/temporary/file
• python AnsiballZ_inventory.py explode
• python AnsiballZ_inventory.py execute

this assumes an inventory already exists when added to the input_inventory field.

Expected results

The built URL should be inventories/<id>/input_inventories when adding association of type input_inventories to a construced_inventory

Actual results

“msg”: “The requested object could not be found at /api/v2/constructed_inventories/24/input_inventories/”

I think this might actually be a duplicate of #13781 and resolved by #13797. Please upgrade to AWX >= 22.1.0 and test again.

[Denney-tech]

@cnfrancis confirmed upgrading resolved the issue. This issue can be closed.
