c# - Entity Framework nesting variables -


i have following setup in entity:

public class t_ht {     public int unid { get; set; }      public string name { get; set; }      public icollection<t_htc> comments { get; set; }  }

and

public class t_htc {     public int unid { get; set; }      public int htid { get; set; }      [foreignkey("htid")]     public t_ht ht { get; set; }      public int cid { get; set; }      [foreignkey("cid")]     public t_c c { get; set; } }

and

public class t_c {     public int unid { get; set; }      public string name { get; set; }      public icollection<t_htc> comments { get; set; } }

where relationships follows:

many t_htc 1 t_ht

one t_ht many t_htc

and

many t_htc 1 t_c

one t_c many t_htc

this setup works fine , achieves need.

however, when querying using c# , linq/entity can following:

var queryht = context.ht.include(x => x.htc);

and

var queryc = context.c.include(x => x.htc);

either of these return single t_ht nested list of t_htc or single t_c nested list of t_htc

however, want achieve is:

a single t_ht, nested list of t_htc, , t_htc include corresponding entry in t_c

i know can achieve performing join joins queryc queryht seems bit of long way go doing this.

surely entity can achieve trying do?

please note variable names have been adjusted purpose of question, , not in actual code.

you can achieve want this:

var queryht = context.ht.include("htc.c");

or strong typed version:

var queryht = context.ht.include(x => x.htc.select(y => y.c));

the strong typed version requires adding using system.data.entity;.

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 ...
