ruby on rails - Accepts nested attributes safe params with jsonb and variable keys -


i attempting allow parameters go through controller data attribute of type jsonb, hash looks so:

data:    { "en" =>     {       "activities_text" => "activities",       "playlists_text" => "playlists",       "additional_playlists_text" => "additional playlists"     },     "es" =>     {       "activities_text" => "actividades",       "playlists_text" => "lista de actividades",       "additional_playlists_text" => "listas de actividades adicionales"     }   }

i got form work , i can save data 1 of language keys. issue happening because in safe params array have following:

text_customization_attributes: [:id, data: [es: [:activities_text, :playlists_text, :additional_playlists_text]]]

i need able allow through both en: es: , potentially other language keys may add in future. naively thought maybe adding both line above this: text_customization_attributes: [:id, data: [en: [:activities_text, :playlists_text, :additional_playlists_text]]] work 1 overrides other , last permitted param wins.

any thoughts on how let through both es: , en: ?

thanks in advanced!

addendum: able save whole hash using 

text_customization_attributes: [:id, data: [en: [:activities_text, :playlists_text, :additional_playlists_text], es: [:activities_text, :playlists_text, :additional_playlists_text]]]

but seems hackish.. there must better way.

as said, there may keys other en or es, somehow, must tell parameters permitted. in case, can map empty hash like, 

text_customization_attributes: [:id, data: {}]

but, bit vulnerable opens door arbitrary input.

reference -> edgeguides:

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 ...
