thank you @KenWhitesell very much for the reply.
I am very new to Python. (I am actually come from a PowerShell background so learning about classes is a relatively new concept).
If I can summarise, from what I can see you have created a method in a class which I can then call upon in other areas of where I want to display data. First example is in your template but I suppose I could also tweak that in my api get data request by using class meta and adding in the function there to display the data back?
I am learning slowly , but having looked at other frameworks, including ones that are in the PowerShell ecosystem, I dont see anything is quite as simple and powerful as Django
