javascript - ember-cli "TypeError: desc.get is not a function" after upgrade of ember-cli -


after updating ember-cli v0.2.7 ember v.1.12.0 i'm having funny behavior causes exception when using computed properties.

used model:

user = ember.object.extend  md5: ""  gravatar: (->    return get_gravatar(@get("md5"))    ).property("md5")

calling u.get("gravatar") in router, aftermodel method, this:

u.get("gravatar") ember.debug.js:15588 uncaught typeerror: desc.get not function     @ object.get (../vendor.js:26142:19)     @ exports.default.mixin.mixin.create.get (../vendor.js:39811:27)     @ eval (eval @ evaluate (unknown source), <anonymous>:1:3)     @ object.injectedscript._evaluateon (<anonymous>:895:55)     @ object.injectedscript._evaluateandwrap (<anonymous>:828:34)     @ object.injectedscript.evaluateoncallframe (<anonymous>:954:21)     @ aftermodel (../v4.js:3438:16)     @ applyhook (../vendor.js:55667:32)     @ object.handlerinfo.runsharedmodelhook (../vendor.js:53668:22)     @ object.handlerinfo.runaftermodelhook (../vendor.js:53651:21)

when digging bit deeper saw error happens in `ember.debug.js @ getter function. 

function get(obj, keyname) {   ...   if (desc) {     return desc.get(obj, keyname);      // -> error while processing route: recipe_edit desc.get not function typeerror: desc.get not function    } else {    ...

the type of descwas same when called u.gravatar directly, i'm not quite sure why doesn't resolved anymore.

desc: object   _cacheable: true   _dependentkeys: array[1]   _readonly: false   isdescriptor: true   __proto__: object

after hours of debugging figured out problem myself. have serializer resolves circular references , removes unnecessary attributes ember object convert json.

in previous ember version worked fine, in version somehow recursive function worked way through object ember framework code , deleted functions ember framework during runtime.

computedpropertyprototype.volatile() computedpropertyprototype.property() exports.default.mixin.mixin.create.clear() exports.default.mixin.mixin.create.popobject() exports.default.mixin.mixin.create.shiftobject() ...

therefore got these weird sounding errors , difficult debug errors, deletion of property happens before causes error.

it bad hacky serializer, hope helps of when stumbling upon same error.
