ember.js - How to I specify a primary key for Ember Data? -

-

my server uses sensorid primary key on sensor model. i've tried following

app.sensorserializer = ds.restserializer.extend({   primarykey: "sensorid" });

based on see in this test, it's not working. i'm getting error:

error while loading route: error: no model found '0'

i'm using custom adapter. response jsonp:

jquery203041337518650107086_1397489458691([{"sensorid":1,"address":"xxx, yyy","latitude":"nnnn","longitude":"mmmm"...

but when inspect data gets returned, it's normal array: 

// app.sensoradapter findall: function(store, type, sincetoken) {   var url = 'http://blahblahblah/?callback=?';   var query = { since: sincetoken };    return new ember.rsvp.promise(function(resolve, reject) {     jquery.getjson(url, query).then(function(data) {       debugger;       // data.foreach(function(s) {       //   s.id = +s.sensorid;       // });       ember.run(null, resolve, data);      }, function(jqxhr) {       jqxhr.then = null; // tame jquery's ill mannered promises       ember.run(null, reject, jqxhr);     });   });

what correct syntax ember data 1.0.0-beta.7?

try this:

app.adapter.map('app.sensor', {   primarykey: 'sensorid' });

i used pyinstaller create standalone exe file pyqt project. did not use single file option because exe created single file option takes long open. therefore, pyinstaller created dist folder contains bunch of files including program.exe file. create setup.exe file place contents of dist folder in program directory , create shortcut in start menu , on desktop. want super simple user. maybe setup.exe files when download program cnet. found inno-setup, looks promising. however, not know if there special considerations because program standalone program create python/pyqt program. thanks! have experience task? there program using task not know about? inno-setup or nsis easiest use. tell them files include , put them , create nice installer you. wrote short tutorial on experiences using innosetup might find helpful: http://www.blog.pythonlibrary.org/2008/08/27/packaging-wxpymail-for-distribution/ note tutorial based around wxpython app wrote, concepts same.
