javascript - How to use sparkpost without a CC and/or BCC recepient? -


here's transmission object:

  if(req.body.bcc === ''){      req.body.bcc = '';    }     if (req.body.cc === '') {      req.body.cc = '';    }     if (req.body.subject === '') {      req.body.subject = 'no subject';    }    if (req.body.source === '') {      req.body.source = '<email omitted>';    }    if (req.body.messagebody === '') {      req.body.messagebody = 'no body text has been entered';    }    var transmission = {      recipients: [        {          address: {            email: req.body.to,            name: 'to recipient'          },          substitution_data: {            recipient_type: 'original'          }        }      ],      cc: [        {          address: {            email: req.body.cc,          },          substitution_data: {            recipient_type: 'cc'          }        }      ],      bcc: [        {          address: {            email: req.body.bcc,          },          substitution_data: {            recipient_type: 'bcc'          }        }      ],      content: {        from: {          name: req.body.source,          email: req.body.source        },        subject: req.body.subject,        text: req.body.messagebody,        html: `<p></p>`      }    };

i have html input forms send entered data req.body, if there's no req.body.cc or req.body.bcc content, happens sparkpost throws error saying unaccessible entity and:

  name: 'sparkposterror',    errors:     [ { message: 'invalid header',         description: 'error while validating header cc: missing header content',         code: '3002' } ],    statuscode: 422 }

if put random number 1 in cc , bcc fields, message sends "to" user sparkpost tells me message failed send 2 recepients. feel i'm missing here because if there no bcc or cc recipients should send email in "to" field , shouldn't have enter random gibberish in cc or bcc send email. has ran issue or have idea how solve problem?

maybe can check if field blank, replace default value sparkpost know i'm not trying send email there, placeholder. if there such thing, haven't found yet.

here example of sending email without cc or bcc. if not have bcc or cc recipients don't include array objects.

{     "options": {         "open_tracking": true,         "click_tracking": true     },   "campaign_id": "test",   "recipients": [     {       "address": {         "email": "to@example.com",         "name": "to recipient"       },          "tags": [],         "substitution_data": {"recipient_type": "original"}      }   ],   "content": {     "from": {       "email": "from@example.com",       "name": "from address"     },     "subject": "my sample subject",     "text": "{{recipient_type}}",     "reply_to": "test@example.com",      "html": "<p>{{recipient_type}}</p>"   } }

here example curl command:

curl -x post \   https://api.sparkpost.com/api/v1/transmissions \   -h 'authorization: your_api_key_here' \   -h 'cache-control: no-cache' \   -d '{     "options": {         "open_tracking": true,         "click_tracking": true     },   "campaign_id": "test",   "recipients": [     {       "address": {         "email": "to@example.com",         "name": "to recipient"       },          "tags": [],         "substitution_data": {"recipient_type": "original"}      }   ],   "content": {     "from": {       "email": "from@example.com",       "name": "from address"     },     "subject": "my sample subject",     "text": "{{recipient_type}}",     "reply_to": "test@example.com",      "html": "<p>{{recipient_type}}</p>"   } }  '

you need put api key , replace to/from addresses ones appropriate test case.

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

jquery - Responsive Navbar with Sub Navbar -

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
