How to use registration(signup/login) modal(bootstrap template) with django views?
I am new to programming. I found nice bootstrap modal for registration, so i put it to my html code and it looks nice but nothing can be pressed or post. Before i was using django and UserCreationForm without modals. So help me to concatenate these two things: so this is my bootstrap modal that i found <!-- Modal --> <div class="modal fade" id="elegantModalForm" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true"> <div class="modal-dialog" role="document"> <!--Content--> <div class="modal-content form-elegant"> <!--Header--> <div class="modal-header text-center"> <h3 class="modal-title w-100 dark-grey-text font-weight-bold my-3" id="myModalLabel"><strong>Войти</strong></h3> <button type="button" class="close" data-dismiss="modal" aria-label="Close"> <span aria-hidden="true">&times;</span> </button> </div> <!--Body--> <form type="post" action="{% url 'common:login' %}"> <div class="modal-body mx-4"> <!--Body--> <div class="md-form mb-5"> <input type="email" name="useremail" id="Form-email1" class="form-control validate"> <label data-error="wrong" data-success="right" for="Form-email1">Ваша почта</label> </div> <div class="md-form pb-3"> <input type="password" id="Form-pass1" class="form-control validate"> <label data-error="wrong" data-success="right" for="Form-pass1">Пароль</label> <p class="font-small blue-text d-flex justify-content-end">Забыли <a href="#" class="blue-text ml-1"> пароль?</a></p> </div> <div class="text-center mb-3"> <button type="button" class="btn blue-gradient btn-block btn-rounded">ок</button> </div> <p class="font-small dark-grey-text text-right d-flex justify-content-center mb-3 pt-2"> или войти с помощью:</p> <div class="row my-3 d-flex justify-content-center"> <!--Facebook--> <button type="button" class="btn btn-white btn-rounded mr-md-3 z-depth-1a"><i class="fab fa-facebook-f text-center"></i></button> <!--Twitter--> <button type="button" class="btn btn-white btn-rounded mr-md-3 z-depth-1a"><i class="fab fa-twitter"></i></button> <!--Google +--> <button type="button" class="btn btn-white btn-rounded z-depth-1a"><i … -
Django orm left join queries without foreign keys

TypeError: 'datetime.date' object is not subscriptable
I'm trying to create a custom template tag which takes 3 arguments. I'm trying to calculate the number of days between two dates, while excluding the weekends days from that count. And depending on the department, the weekend is different for each user. So I need start_date, end_date, user_id to be passed onto the template tag function. This is what I have done so far: from django import template from datetime import datetime, timedelta, date register = template.Library() @register.filter('date_diff_helper') def date_diff_helper(startdate, enddate): return [startdate, enddate] @register.filter(name='date_diff') def date_diff(dates, user_id): start_date = dates[0] end_date = dates[1] count = 0 weekends = ["Friday", "Saturday"] for days in range((end_date - start_date).days + 1): if start_date.strftime("%A") not in weekends: count += 1 else: start_date += timedelta(days=1) continue if start_date == end_date: break start_date += timedelta(days=1) return count This is how I'm calling these functions in template: {{ leave.start_date|date_diff_helper:leave.end_date|date_diff:leave.emp_id }} When I run the code, it gives me TypeError saying 'datetime.date' object is not subscriptable. When I tried to check the type of dates parameter in date_diff function, it says: < class 'list'> < class 'datetime.date'> But when it tries to assign start_date as the first date object, as in start_date = dates[0], it throws … -
Does 'creating' a new record override existing ones with same key?
The first code below both creates (if it doesn't exist yet) and override (if it exists) record in db. It's convenient. I would like to know if this creates problem in the DB. I reviewed the table records and it doesn't create duplicates. record = Foo(key='123', value='Hello) record.save() or try: foo_q = Foo.objects.get(key='123') foo_q.value = 'Hello' foo_q.save() except: record = Foo(key='123', value='Hello) record.save() It works but is it safe to continue using or should I query if it exists and update the model. -

Exception in thread django-main-thread: TypeError:__init__() got an unexpected keyword argument 'fileno'
I am trying to perform load tests on a django application with locust. However, when I try to perform these with multiple simulated users, I get the following error: Exception in thread django-main-thread: Traceback (most recent call last): File "/usr/lib/python3.6/threading.py", line 916, in _bootstrap_inner self.run() File "/usr/lib/python3.6/threading.py", line 864, in run self._target(*self._args, **self._kwargs) File "/home/<user>/.local/lib/python3.6/site-packages/django/utils/autoreload.py", line 54, in wrapper fn(*args, **kwargs) File "/home/<user>/.local/lib/python3.6/site-packages/django/core/management/commands/runserver.py", line 139, in inner_run ipv6=self.use_ipv6, threading=threading, server_cls=self.server_cls) File "/home/<user>/.local/lib/python3.6/site-packages/django/core/servers/basehttp.py", line 213, in run httpd.serve_forever() File "/usr/lib/python3.6/socketserver.py", line 241, in serve_forever self._handle_request_noblock() File "/usr/lib/python3.6/socketserver.py", line 315, in _handle_request_noblock request, client_address = self.get_request() File "/usr/lib/python3.6/socketserver.py", line 503, in get_request return self.socket.accept() File "/usr/lib/python3.6/socket.py", line 210, in accept sock = socket(self.family, type, self.proto, fileno=fd) TypeError: __init__() got an unexpected keyword argument 'fileno' This error seems very weird to me, because the socket __init__() function is part of a default library in which this error shouldn't occur.

How to avoid the error This field is required without changing the model field?
How to avoid the error This field is required in modellformset without changing the model fields and allowing to call the form_valid method instead of form_invalid. That is, if the model is created, all fields are required, if the fields are empty, then it simply does not save the model, but validation passes. Now I get that all the forms must be filled in, but the user can only memorize what he needs, and leave the rest empty. Is there a solution? views.py class SkillTestCreateView(AuthorizedMixin, CreateView): model = Skill form_class = SkillCreateForm template_name = 'skill_create.html' def get_context_data(self, **kwargs): context = super(SkillTestCreateView, self).get_context_data(**kwargs)) context['formset_framework'] = SkillFrameworkFormSet(queryset=Skill.objects.none()) context['formset_planguage'] = SkillPLanguageFormSet(queryset=Skill.objects.none()) context['tech_group'] = Techgroup.objects.all() return context def post(self, request, *args, **kwargs): if 'framework' in request.POST: form = SkillFrameworkFormSet(self.request.POST) if form.is_valid(): return self.form_valid(form) else: return self.form_invalid(request) elif 'language' in request.POST: form = SkillPLanguageFormSet(self.request.POST) if form.is_valid(): return self.form_valid(form) else: return self.form_invalid(request) else: return self.form_invalid(request) def form_valid(self, form): """If the form is valid, redirect to the supplied URL.""" for form in form: self.object = form.save(commit=False) self.object.employee =Employee.objects.get(pk=self.kwargs['pk']) employee_current_technology = Technology.objects.filter(skill__employee__id=self.kwargs['pk']) if self.object.technology not in employee_current_technology: self.object.save() return redirect("profile", pk=self.kwargs['pk']) def form_invalid(self, request): return render(request, 'skill_create.html', {'formset_framework': SkillFrameworkFormSet(queryset=Skill.objects.none()), 'formset_planguage': SkillPLanguageFormSet(queryset=Skill.objects.none())}) Is the behavior in which I need … -
django templates index of array does not work

Improve the calculation of distances between objects in queryset
I have next models in my Django project: class Area(models.Model): name = models.CharField(_('name'), max_length=100, unique=True) ... class Zone(models.Model): name = models.CharField(verbose_name=_('name'), max_length=100, unique=True) area = models.ForeignKey(Area, verbose_name=_('area'), db_index=True) polygon = PolygonField(srid=4326, verbose_name=_('Polygon'),) ... Area is like city, and zone is like a district. So, I want to cache for every zone what is the order with others zones of its area. Something like this: def get_zone_info(zone): return { "name": zone.name, ... } def store_zones_by_distance(): zones = {} zone_qs = Zone.objects.all() for zone in zone_qs: by_distance = Zone.objects.filter(area=zone.area_id).distance(zone.polygon.centroid).order_by('distance') zones[zone.id] = [get_zone_info(z) for z in by_distance] cache.set("zones_by_distance", zones, timeout=None) But the problem is that it is not efficient and it is not scalable. We have 382 zones, and this function get 383 queries to DB, and it is very slow (3.80 seconds in SQL time and 4.20 seconds in global time). is there any way efficient and scalable to get it. I had thought in something like this: def store_zones_by_distance(): zones = {} zone_qs = Zone.objects.all() for zone in zone_qs.prefetch_related(Prefetch('area__zone_set', queryset=Zone.objects.all().distance(F('polygon__centroid')).order_by('distance'))): by_distance = zone.area.zone_set.all() zones[zone.id] = [z.name for z in by_distance] This obviously does not work, but something like this, caching in SQL (prefetch related) the zones ordered (area__zone_set). -

How to make a model in django without predefined attributes?
I am little bit confused with the django model as the title said. I also cannot find any posts in google. Let's say in the normal way, we will have a model like this: class something(models.Model): fName = models.TextField() lName = models.TextField() ...... lastThings = models.TextField() However, I don't want to have a model like this. I want to have a model with no predefined attributes. In order words, I can put anythings into this model. My thought is like can I use a loop or some other things to create such model? class someModel(models.Model): for i in numberOfModelField: field[j] = i j+=1 Therefore, I can have a model that fit in any cases. I am not sure is it clear enough to let you understand my confuse. Thank you -

Most Pythonic/Django way to dynamically load client libraries at runtime
I'm writing a Django application in which we will have multiple client libraries that make calls to third party APIs. We want to be able to determine which client library to load at runtime when calling different endpoints. I'm trying to determine the most Django/Pythonic way to do this The current idea is to store class name in a model field, query the model in the View, and pass the class name to a service factory that instantiates the relevant service and makes the query. I've also considered writing a model method that uses reflection to query the class name For example lets say we have a model called Exchange that has an id, a name, and stores the client name. class Exchange(models.Model): exchange_name = models.CharField(max_length=255) client_name = models.CharField(max_length=255) def __str__(self): return self.exchange_name Then in the View we might have something like: from rest_framework.views import APIView from MyProject.trades.models import Exchange from django.http import Http404 from MyProject.services import * class GetLatestPrice(APIView): def get_object(self, pk): try: exchange = Exchange.objects.get(pk=pk) except Exchange.DoesNotExist: raise Http404 def get(self, request, pk, format=None): exchange = self.get_objectt(pk) service = service_factory.get_service(exchange.client_name) latest_price = service.get_latest_price() serializer = PriceSerializer(latest_price) return Response(serializer.data) This syntax may not be perfect but it hasn't been … -

How to render two form fields as one field in Django forms?
I'm working on Django application where I need to render a form differently. The form contains multiple fields related to a person. Firstname Lastname email address city country Phone Pincode There are two flows in my application. In the first flow I can render all the form fields and save them when the user enters some data and submit. But in the second flow, I need to display only three fields as below. Name - Combination of Firstname and Lastname Email Phone The data entered in the name field should be split and saved as Firstname and Lastname. And for other remaining mandatory fields in the form that are not rendered, I can fill empty values and save the model in Backend. What is the best way to render the forms differently for each flow?
