java - BasicDBObjectBuilder not appending mutiple criteria for a single object -


i using java driver mongo-db , trying add multiple query criteria using basicdbobjectbuilder. have text field xml stored string using regex form query.

below query , output getting:

regexquery.put("request_xml",basicdbobjectbuilder .start("$regex", ".*main>[\r\n]<.?.?.?.?action>"+mainvalue+".*") .add("$regex", ".*details>[\r\n]<.?.?.?.?action>" + detailvalue+ ".*").get()); regexquery.put("name", "video");

what getting query : 

{ "request_xml" : { "$regex" : ".*details>[\r\n]<.?.?.?.?action>change.*"} , "name" : "video"}

the first part .start("$regex", ".main>[\r\n]<.?.?.?.?action>"+mainvalue+".") not getting added query.

can please let me know issue ?

you overwriting key value pair. "$regex", ".*details>[\r\n]<.?.?.?.?action>" + detailvalue+ ".*" overwrites "$regex", ".*main>[\r\n]<.?.?.?.?action>"+mainvalue+".*".

use $or pass both regex expression.

something like

basicdbobject regexquery = new basicdbobject(); regexquery.put("$or", arrays.aslist(new basicdbobject("request_xml", new basicdbobject("$regex", ".*main>[\r\n]<.?.?.?.?action>"+".*")),                 new basicdbobject("request_xml", new basicdbobject("$regex", ".*details>[\r\n]<.?.?.?.?action>"+".*")))); regexquery.put("name", "video");

this should output query like

{ "$or" : [{ "request_xml" : { "$regex" : ".*main>[\r\n]<.?.?.?.?action>.*" } }, { "request_xml" : { "$regex" : ".*details>[\r\n]<.?.?.?.?action>.*" } }], "name" : "video" }

using 3.x driver

import static com.mongodb.client.model.filters.or; import static com.mongodb.client.model.filters.regex; bson regexquery = or(regex("request_xml", ".*main>[\r\n]<.?.?.?.?action>"+".*"), regex("$regex", ".*details>[\r\n]<.?.?.?.?action>"+".*"));

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

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
