问题 I am creating a simple RESTful interface on one of my apps and I have been looking at what's available out there: I've looked at: django-piston but it seems abandoned and the feedback on it is not great. django-dynamicresponse which seems rather bare A lot of packages from here However, looking at examples of how these packages it seems that they don't really provide much.

问题 im new to atk4, but i couldn't find some simple examples for using CRUD with many:many relationships between tables.

问题 I'm a client side developer with little experience of server side, and I'm struggling to understand how to make a database-backed website without requiring users to login. The usecase is fairly straightforward. The user lands on a website, uploads an image, and performs some processing to that image. Clicking 'share' POSTs JSON to my endpoint, stores it in a DB, and returns a unique URL in a textbox (eg, https://example.com/art/12345) which allows the user to share their artwork with others,

问题 The non-GET instance action $save doesn't work in my example. I always get the Error, that $save is not a function. The problem is, I don't know where I have to define the $scope.example = new Resource(); , because in my example I'm using 2 Controllers.
