JPA OneToMany with composite keys in parent and children -


i have 2 tables represent authorizations users manage applications on given offices. 1 table has composite pk of office , user , holds information those, other has composite key of office, user , applicationid (table 2 holds no other information)

+---------------+           +---------------+   |    table1     |           |    table2     | +---------------+           +---------------+   | - userid      | 1       n | - userid      |  | - officeid    | <-------> | - officeid    |  | <other data>  |           | - applicid    |     +---------------+           +---------------+

how represent in jpa? @ moment have this:

@data @embeddable public class table1_pk implements serializable {       private bigdecimal officeid;     private string userid; }   @data @embeddable public class table2_pk implements serializable {     @embedded     private table1_pk table1pk;      private int applicid; }

and entities: @entity public class table1 implements serializable { @embeddedid private table1_pk table1id; }

@entity public class table2 implements serializable {     @embeddedid     private table2_pk table2id; }

is right far? how can represent onetomany relation 2 table have?

the key field names same on both tables (so userid called "userid" on both table1 , table2 in db, table2 has field more application code)

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 ...
