user interface - I cannot format the date in the way I want in sap.m.DatePicker -


i have couple of weird problems sap.m.datepicker. do, searched topics via google, helped me, not entirely.

what want achieve: have sap.ui.table.column in sap.ui.table.table , column should have template: new sap.m.datepicker() date formatted dd.mm.yyyy.

what have done far: using sap.ui.model.odata.v2.odatamodel() populate sap.ui.table.table odata service. went until decided have dates in corresponding column displayed in prefered format. @ first, using these properties, related formatting in datepicker's constructor:

displayformat: "dd.mm.yyyy", valueformat: "yyyy-mm-dd", //... value = "{" + fieldname + "}"

in way, dates displayed in following format: sun aug 06 2017 03:00:00 gmt+0300 (fle daylight time) (i don't know how express using format string). remember yesterday reading in documentation, when have binding, displayformat ignored, me ... don't understand why that.

anyway, found solution, gives advice set value this:

value: {                 path: colname,                 type: new sap.ui.model.type.date({                     pattern: "dd.mm.yyyy"                     //source: { pattern: "yyyy-mm-dd hh:mm:ss:fff" }                 })             }

at first, seems work , date formatted , displayed correctly, when try modify date in row... example, choose august 6th 2017. saved database via odata service 2017-06-08 00:00:00.000 not august 6th june 8th. select august 2nd - in database see 2017-02-08 00:00:00.000 - february 8th. seems month , day switched. if select, example, august 30th, change not saved. far understand problem - there no month number 30, refuses save it. totally makes sense. :d

then tried add/uncomment line source: {}. every row date column shows empty, if every row in database has null value in date column.

next, tried remove displayformat: "dd.mm.yyyy", valueformat: "yyyy-mm-dd" definition of datepicker template - nothing changed. interesting - no matter if remove 2 lines or not, can still change date of row (the change gets saved database), although month , day still switched.

then came accross solution, said, should add formatter this:

value: {             path: colname,             formatter: function (val) {                 return sap.ui.core.format.dateformat.getdateinstance({ pattern: "dd-mm-yyyy" }).format(val);             }         };

this way, seems work should. may ask did give using format dd.mm.yyyy. answer "no!", doesn't work.

so, main question, want ask: what's wrong formatting? no matter other symbol use, comma, dash, works (dd-mm-yyyy or dd,mm,yyyy). dates displayed corresponding symbol. when try use dd.mm.yyyy, errors that: enter image description here , that: enter image description here

thank help! appreciate it!

edit: have come idea workaround issue. unfortunately, doesn't work , produces exact same error, described above pictures. here nonworking solution: return sap.ui.core.format.dateformat.getdateinstance({ pattern: "dd-mm-yyyy" }).format(val).replace(/\-/g, '.');

try using "datevalue" + "displayformat" properties here:

<datepicker     datevalue="{testmodel>/mydate}"     displayformat="dd.mm.yyyy" />

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer

jquery - Responsive Navbar with Sub Navbar -

good day, forgive me nav vocabulary not best. if question confusing apologize. i'm working on navigation bar needs centered on page @ 768px , above. items in nav open (or perhaps toggle) subnav lives directly below. these nav should appear centered on page. i have been able work through responsive portion of nav bar, having main items align vertically , sub nav menu of each item roll out below, , gave them indent separation. working well. however, issue not responsive side, behavior @ width greater 768px. happens toggling menu's sub navigation pushes other main items down page below sub nav. here's code: $(document).ready(function () { //stick in fixed 100% height behind navbar don't wrap $('#slide-nav.navbar-inverse').after($('<div class="inverse" id="navbar-height-col"></div>')); $('#slide-nav.navbar-default').after($('<div id="navbar-height-col"></d
