We think this is dangerous. It is likely this function will move once we figure out how to properly annotate this RISKY behavior!" The BIG-IP REST API for this particular endpoint has two fields which are mutually exclusive; disabled and enabled. When using this SDK API, you may do the following d = api.tm.gtm.datasources.datasource.load(name='foo') d.update(enabled=False) You might expect that the behavior of the following... if d.enabled: print("enabled") else: print("disabled") ...would result in "enabled" being printed, but that would not be the case; BIG-IP will specify that "enabled" is True and that the following is also now True d.disabled == True This behavior of setting a different variable instead of the one that you specified, may not be obvious to the casual user. Therefore, this method will set appropriate sister variables to be the negation of the variable you set. Therefore d.enabled = True will also do the following automatically d.disabled = False This behavior will allow the SDK to behave according to most users expectations, shown below d.update(enabled=False) if d.enabled: print("enabled") else: print("disabled") which will print the following "disabled" Likewise, checking for d.disabled would return True.
