Hi I am following up on this question here and working through a proof of concept for a SPA using our Company database data from a series of examples / articles Using Web API 2
To help others.
The problem was as I was adapting the work through to Database first approach and I had not correctly created my model file
To help with debug on the running web app I posted a request to my Get API
api/RequistionsForApprovals
This returned a blank return, proving the problem was with my data reading not my knock out models and bindings. After reading up a bit more I thought I had not defined correctly the primary key of the EF model of my SQL view, therefore I needed to edit the edmx file as in the case here.
However I could not find my edmx file in my solution. Therefore I went through the process of adding a new item, Data, then choosing ADO.net Entity Data model. This created the mappings to my model class and a context which I was able to use with my controller
A bit of a simple mistake, but that is often the case when learning a new process!
Hope it helps anyone else
