python - How to Lengthen the Username Field on Django User Model? -


i have django web application deployed on heroku. i'm using django's user model authentication. goal lengthen username field 30 characters 100 characters.

i overrode default user model own abstractuser model:

class abstractuser(abstractbaseuser, permissionsmixin):     username = models.charfield(         _('username'),         max_length=30,         unique=true,         help_text=_('required. 100 characters or fewer. letters, digits , @/./+/-/_ only.'),         validators=[             validators.regexvalidator(                 r'^[\w.@+-]+$',                 _('enter valid username. value may contain '                   'letters, numbers ' 'and @/./+/-/_ characters.')             ),         ],         error_messages={             'unique': _("a user username exists."),         },     )     first_name = models.charfield(_('first name'), max_length=30, blank=true)     last_name = models.charfield(_('last name'), max_length=30, blank=true)     email = models.emailfield(_('email address'), blank=true)     is_staff = models.booleanfield(         _('staff status'),         default=false,         help_text=_('designates whether user can log admin site.'),     )     is_active = models.booleanfield(         _('active'),         default=true,         help_text=_(             'designates whether user should treated active. '             'unselect instead of deleting accounts.'         ),     )     date_joined = models.datetimefield(_('date joined'), default=timezone.now)

i want update max_length of username field 30 100. can locally without issue updating line max_length=30 max_length=100, running python manage.py makemigrations , python manage.py migrate.

however, migration file created in virtual environment (venv\lib\site-packages\django\contrib\auth\migrations) folder i'm not sure deploy heroku. have entire venv folder excluded through .gitignore file. not have venv folder on heroku.

where/how should deploy , apply migration file heroku?

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
