using ember 1.13.2 ember data 1.13.4 in conjunction rails backend. trying implement hmac authentication ember , ember data (restadapter) class authhelper authheader: (adapter)-> ... frontend.applicationadapter = ds.restadapter.extend( headers: (-> 'authorization': new authhelper().authheader(@) ).property().volatile()) for need url request going send to. how can url? or need construct manually collecting host , pluralized models name? get params ? update i able accomplish following code: ember.$.ajaxprefilter (options, oriopt, jqxhr) -> authheader = authhelper.authheader(options.url) jqxhr.setrequestheader("authorization", authheader) return the complete solution can found here: https://github.com/psunix/js-frameworks-api-auth maybe knows more ember way doing this.

if have subscription inside tracker.autorun() , publish takes variable selector, means every time, return may vary, minimongo cache docs returned publications? or each time, clears documents , preserve returned docs previous publication? meteor clever enough keep track of current document set each client has each publisher. when publisher reruns, knows send difference between sets. let's use following sequence example: subscribe posts: a,b,c rerun subscription posts b,c,d server sends removed message a , added message d . note not happen if stopped subscription prior rerunning it.

i have object dates: class myobj { public datetime? date {get; set;} } as can see date nullable. possible use linq 's groupby method group list<myobj> dates including null s? to like: {elements_with_date_1, elements_with_date_2, ..., elements_with_no_date} ? the groupby -method extension-method, means static method accepts date parameter. written listwithnulls.groupby() treated groupby(listwithnulls) . because of behavior, null -values can handled , don't nullreferenceexception . have @ extension-methods definition. helps understand how can work them: public static ienumerable<igrouping<tkey, tsource>> groupby<tsource, tkey>(this ienumerable<tsource> source, func<tsource, tkey> keyselector); you can see first argument written this ienumerable<tsource> source , enables short-handle source.groupby() .

example have 10 textbox , each has same attribute different value, example have attribute data-same different value , have in code $('#test').each(function(){ $(this).val(); }); and want filter result using attribute of each textbox. how it? thinking on doing this $('#test').each(function(){ $('[data-same="val1"]',this).val(); }); but i'm not sure it. use attr() $('#test').each(function(){ var attributevalue = $(this).attr('data-same'); //do whatever want value }); also, code indicates have same id multiple elements. avoid , use classes or attributes instead. $('[data-same]').each(function(){ var attributevalue = $(this).attr('data-same'); //do whatever want value }); see why bad thing have multiple html elements same id attribute?

i've started refactor 1 of commands in symfony2 (2.7) application. quick question - is there way write event listener listens custom event , handles printing message on screen? suppose there class emits event, example, on successful save db. need listen event , when it's emitted, want print message on screen: "your entity has been saved successfully" , don't want in command code because in opinion when there many outputs in commands, execute method becomes bit messy. that's why started search way of handling system events proper information user. thanks! maybe should try consolelogger ?
