Pulp

Issue #6147

Updated by dalley about 4 years ago

The serializer does the correct thing, because the serializer does not use Repository.latest_version()

 However, underneath the hood, Pulp and plugin writers might have a problem, because if the "latest version" was deleted, Repository.latest_version() will return "None" instead of the one prior to the deleted one. 

 ~~~ 

 In [1]: RpmRepository.objects.all()[1].latest_version()     

 In [2]: RepositoryVersion.objects.filter(repository=RpmRepository.objects.all()[1])                                     
 Out[2]: <QuerySet [<Repository: targetrepo; Version: 0>]> 

 In [3]: RpmRepository.objects.all()[1].last_version         
 Out[3]: 1 

 


 ~~~ 

 So what the JSON API returns and what the internal APIs return do not match up.
