Implementing the workaround doesn't require changing your reload method every time you change your model. The particular use case in the ticket involved only one attribute that needed to be re-loaded, so it was easiest to just re-assign that attribute. If you have many (or potentially all) fields that need to be reloaded there is no reason you can't use the field information contained in the model's _meta.fields list to do a more wholesale "reload" that doesn't rely on knowing what attributes, specifically, need to be re-assigned. Essentially you probably want to implement the code that would be placed in Django core if this were to be supported by Django, only in your own code. You'll have to dig into some of the model internals probably to figure out how to do it, but I don't think it is that hard. Relying on internals means it could break if they change in the future but I think you'd only need to use some basic stuff that is unlikely to change at this point.
