activerecord - Spree Ruby on rails query -


trying learn ruby , spree

i've got query in controller that's running fine:

@products = spree::lineitem.select("spree_line_items.id,  spree_variants.sku, spree_products.name, spree_line_items.quantity") .joins(:order).joins(:variant).joins(:product) .where(spree_orders: {state: 'complete', shipment_state: 'ready'})

when run query in view

<% @products.each |lineitem| %> <%= lineitem.id %><br> <% end %>

this works fine , spits out of id's i'm wanting output other bits, sku, name , quantity other tables. how bring them in here?

if reference them same id delegationerror.

to answer query, can do

@products = spree::lineitem.select("spree_line_items.id,  spree_variants.sku variant_sku, spree_products.name product_name, spree_line_items.quantity quantity") .joins(:order).joins(:variant).joins(:product) .where(spree_orders: {state: 'complete', shipment_state: 'ready'})

then access sku lineitem.variant_sku, name lineitem.product_name , quantity lineitem.quantity.

but appropriate way achieve is

spree::lineitem.joins(:order).includes(variant: :product) .where(spree_orders: {state: 'complete', shipment_state: 'ready'})

and access attributes lineitem.sku, lineitem.name, lineitem.quantity

we can because sku , name delegated variant in line_item model. same reason getting delegationerror.

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 ...
