Example throws exception

htammen commented 9 years ago

Hi, when I try to run your example from the examples folder I get the following error as soon as I try to read the users entityset.

/Users/helmut/projekte/node/simple-odata-server-test/node_modules/simple-odata-server/lib/prune.js:15
        var propDef = type[prop];

Unfortunately I'm not able to debug with node-debug (cannot set a breakpoint, don't know why, I'm quite new to node). Any ideas whats wrong with the example / the odata-server?

Here's my code:

var http = require('http');
var Datastore = require('nedb');
var db = new Datastore( { inMemoryOnly: true });
var ODataServer = require("simple-odata-server");

var model = {
    namespace: "myns",
    entityTypes: {
        "myns.UserType": {
            "_id": {"type": "Edm.String", key: true},
            "test": {"type": "Edm.String"},            
        }
    },   
    entitySets: {
        "users": {
            entityType: "myns.UserType"
        }
    }
};

var odataServer = ODataServer("http://localhost:1337")
    .model(model)
    .onNeDB(function(es, cb) { cb(null, db)});

http.createServer(odataServer.handle.bind(odataServer)).listen(1337);

db.insert({"_id": "1", "test": "a"});
db.insert({"_id": "2", "test": "b"});
db.insert({"_id": "3", "test": "c"});
db.insert({"_id": "4", "test": "d"});
db.insert({"_id": "5", "test": "e"});

Best regards Helmut

Hi Helmut,

entity type should not include namespace in the model

your fixed code should look like

var http = require('http');
var Datastore = require('nedb');
var db = new Datastore( { inMemoryOnly: true });
var ODataServer = require("simple-odata-server");

var model = {
    namespace: "myns",
    entityTypes: {
        "UserType": {
            "_id": {"type": "Edm.String", key: true},
            "test": {"type": "Edm.String"},            
        }
    },   
    entitySets: {
        "users": {
            entityType: "myns.UserType"
        }
    }
};

var odataServer = ODataServer("http://localhost:1337")
    .model(model)
    .onNeDB(function(es, cb) { cb(null, db)});

http.createServer(odataServer.handle.bind(odataServer)).listen(1337);

db.insert({"_id": "1", "test": "a"});
db.insert({"_id": "2", "test": "b"});
db.insert({"_id": "3", "test": "c"});
db.insert({"_id": "4", "test": "d"});
db.insert({"_id": "5", "test": "e"});

Thank you very much Jan for this quick response, nearly real time :-). It's working :+1: Maybe you should update your example. I've copied the code from it.

Thanks Helmut
