The driver layer returns entities as dicts containing the ids of the
actor (e.g. user or group), target (e.g. domain or project) and role.
If it is an inherited role, then this is also indicated. Examples:
For a non-inherited expanded assignment from group membership:
{'user_id': user_id,
'project_id': project_id,
'role_id': role_id,
'indirect': {'group_id': group_id}}
or, for a project inherited role:
{'user_id': user_id,
'project_id': project_id,
'role_id': role_id,
'indirect': {'project_id': parent_id}}
or, for a role that was implied by a prior role:
{'user_id': user_id,
'project_id': project_id,
'role_id': role_id,
'indirect': {'role_id': prior role_id}}
It is possible to deduce if a role assignment came from group
membership if it has both 'user_id' in the main body of the dict and
'group_id' in the 'indirect' subdict, as well as it is possible to
deduce if it has come from inheritance if it contains both a
'project_id' in the main body of the dict and 'parent_id' in the
'indirect' subdict.
This function maps this into the format to be returned via the API,
e.g. for the second example above:
{
'user': {
{'id': user_id}

'scope': {
'project': {
{'id': project_id}

"""Format an assignment entity for API response.
The driver layer returns entities as dicts containing the ids of the
actor (e.g. user or group), target (e.g. domain or project) and role.
If it is an inherited role, then this is also indicated. Examples:
For a non-inherited expanded assignment from group membership:
{'user_id': user_id,
'project_id': project_id,
'role_id': role_id,
'indirect': {'group_id': group_id}}
or, for a project inherited role:
{'user_id': user_id,
'project_id': project_id,
'role_id': role_id,
'indirect': {'project_id': parent_id}}
or, for a role that was implied by a prior role:
{'user_id': user_id,
'project_id': project_id,
'role_id': role_id,
'indirect': {'role_id': prior role_id}}
It is possible to deduce if a role assignment came from group
membership if it has both 'user_id' in the main body of the dict and
'group_id' in the 'indirect' subdict, as well as it is possible to
deduce if it has come from inheritance if it contains both a
'project_id' in the main body of the dict and 'parent_id' in the
'indirect' subdict.
This function maps this into the format to be returned via the API,
e.g. for the second example above:
{
'user': {
{'id': user_id}
},
'scope': {
'project': {
{'id': project_id}
},
'OS-INHERIT:inherited_to': 'projects'
},
'role': {
{'id': role_id}
},
'links': {
'assignment': '/OS-INHERIT/projects/parent_id/users/user_id/'
'roles/role_id/inherited_to_projects'
}
}
