I am looking to perform a case insensitive comparison in Ansible with selectattr.
The below works, but does not guarantee a case insensitive comparison.
__app_pools_info.app_pools | selectattr('attributes.processModel.userName', 'equalto', username_var | lower) | map(attribute='name') | list
The below fails with an error stating processModel is undefined.
__app_pools_info.app_pools | selectattr('attributes.processModel.userName' | lower, 'equalto', username_var | lower) | map(attribute='name') | list
Another attempt fails due to too many arguments being passed to to_lower. I expect I'm not understanding the use of this option.
__app_pools_info.app_pools | selectattr('attributes.processModel.userName', 'lower,' 'equalto', username_var | lower) | map(attribute='name') | list
The below would work, but the username has a forward slash in the name which causes escape issues The error was: re.error: bad escape.
__app_pools_info.app_pools | selectattr('attributes.processModel.userName', 'search', username_var | lower, ignorecase=true) | map(attribute='name') | list
You can use match with regex flags:
__app_pools_info.app_pools | selectattr('attributes.processModel.userName', 'match', '^' + (username_var | regex_escape) + '$', ignorecase=true) | map(attribute='name') | list
The regex_escape filter handles the forward slash issue you encountered, and ignorecase=true provides case-insensitive matching.
