Here's the json: [{"model": "Candidate", "pk": 1, "fields": {"Mag Min": "22.3", "Mask Blue": "7", "Image Path": "DES0042-441410208310-44133023.png", "Mag Max": "23.8", "Mask Red": "6", "Rank": "10", "SB Max": "24.55", "SB Min": "23", "Vis End": "12/5/2016", "position angle": "300", "RA": "10.20279", "Vis Start": "8/10/2016", "Dec": "-44.12075", "ID": "DESJ000-000"}}, {"model": "Candidate", "pk": 2, "fields": {"Mag Min": "22.3", "Mask Blue": "7", "Image Path": "DES0042-441410208310-44133023.png", "Mag Max": "23.8", "Mask Red": "6", "Rank": "10", "SB Max": "24.55", "SB Min": "23", "Vis End": "12/5/2016", "position angle": "300", "RA": "10.20279", "Vis Start": "8/10/2016", "Dec": "-44.12075", "ID": "DESJ001-000"}}]

Brian, I think you are just missing the name of the app when specifying the model, it should be:

[ { "model": "candidates.cantidate", ... } ]

[bnord]

How do we know that app is "candidates" and model is "candidate"?

[afausti]

In django terminology masterlist is the project name. Inside the project you can have several apps in this case we have one called candidates. Models are created per app and their names correspond to the class names in models.py
