Django - DATE_FORMAT not work properly, i can't force Django to use a Date format
(First of all sorry for my bad English) I'm having a problem with the Date Formats, I'm from Argentina and here we use the Date Format dd/mm/yyyy. Well when I use a computer configured in spanish language the I see the dates and the date inputs perfect!for example in a detail view I see this in a date dd/mm/yyy but in any computer like my own one I see this mm/dd/yyyy And this generate a problem with my forms, in an especific case on my app when I go to save in the database a date input 03/01/2017 (Jan. 3. 2017) saves March 1 2017 ...... This is the configuration on the settings file USE_L10N = False DATE_FORMAT = 'd/m/Y' DATE_INPUT_FORMATS = ('d/m/Y') USE_TZ = True I use only DATE_FORMAT too, TZ False... I really don't know if is any way to force Django to use the format dd/mm/yyyy for all the cases. -
Django AllAuth - Google - choose username
We are using Django-allauth to allow users to signup and login using Google. The problem is that it automatically chooses first name from Google account as a username. Is it possible to make users to fill the username manually? I didn't find such settings in Allauth-google docs. These are ACCOUNT_ settings from settings.py ACCOUNT_AUTHENTICATION_METHOD = "username_email" ACCOUNT_CONFIRM_EMAIL_ON_GET = True ACCOUNT_EMAIL_REQUIRED = True ACCOUNT_EMAIL_VERIFICATION = "mandatory" ACCOUNT_EMAIL_SUBJECT_PREFIX = EMAIL_SUBJECT_PREFIX ACCOUNT_EMAIL_CONFIRMATION_COOLDOWN = 1 ACCOUNT_LOGIN_ON_EMAIL_CONFIRMATION = True ACCOUNT_PRESERVE_USERNAME_CASING = False ACCOUNT_USERNAME_MIN_LENGTH = 4 ACCOUNT_USERNAME_REQUIRED = True There is no such setting starting SOCIALACCOUNT_ in Docs. -
Django dynamic responsive forms
I have been learning django and wanted to create dynamic forms.So far, I have only created a dropdown menu. I wanted to create additional form fields for user input once a choice is made. I'm using ModelForm for the creation of dropdown menu as menu items will be decided during the runtime. My dropdown menu My views.py file from django.shortcuts import render,redirect from django.http import HttpResponse from .forms import ChoiceForm def hello(request): if request.method == 'POST': print 'in post' form = ChoiceForm(request.POST) if form.is_valid(): return HttpResponse(str(form.cleaned_data)) else: return HttpResponse('Invalid data') else: form = ChoiceForm() return render(request, 'choices.html', {'form': form}) My Models.py file from django.db import models from google.cloud import storage # Create your models here. class QueryInfo(models.Model): client = storage.Client() bucket_list = client.list_buckets() #Choice fields for user to select #choices must be in a iterable of length 2 BUCKET_CHOICES = ( (str(bucket_name.name), str(bucket_name.name)) for bucket_name in bucket_list ) selected_bucket = models.CharField(max_length=256,choices=BUCKET_CHOICES) My form file: from django import forms from gui.models import QueryInfo class ChoiceForm(forms.ModelForm): class Meta: model = QueryInfo fields = ['selected_bucket'] -
raw SQL in django views show error
For some special reasons we had to perform raw query in view.py file. (There is some page that user types an SQL query and sends it so our system and we should perform it and show the result of tat query) def query(request): result = None if request.method == "POST": form = forms.QueryForm(request.POST) if form.is_valid(): query_text = form.cleaned_data['query'] with connection.cursor() as cursor: try: cursor.execute(query_text) result = cursor.fetchall() except: result = cursor.statusmessage else: form = forms.QueryForm() return render(request, "portal/query.html", { 'form': form, 'result': result }) if we run something like SELECT * FROM table1, the try part would successfully run and if some queries that do not return some rows like UPDATE, the except part works. My question is that if we perform some meaningless queries like sakufhskghks, we want to see the error from DB, or any type of error from DB. Is that possible? tnx -

Connect 3 models in Django to access other model data

How to pass Django server variable into React jsx?
I have a Django view that passes a model queryset and a string variable (order) class RestaurantListView(generic.ListView): model = Restaurant context_object_name = 'restaurants' template_name = 'routeyourfood/restodetails.html' paginate_by = 4 @method_decorator(require_GET) def dispatch(self, request, *args, **kwargs): return super(RestaurantListView, self).dispatch(request, *args, **kwargs) def get_queryset(self, **kwargs): self.pids = self.request.session['place_ids'] self.order = self.kwargs['order'] self.ordering_dict = { 'rating-asc': 'rating', 'rating-desc': '-rating', 'name-asc': 'name', 'name-desc': '-name', 'distance-asc': 'distance_from_route', 'distance-desc': '-distance_from_route' } if self.order == 'default': return Restaurant.objects.filter(place_id__in=self.pids) return Restaurant.objects.filter(place_id__in=self.pids).order_by(self.ordering_dict[self.order]) def get_context_data(self, **kwargs): context = super(RestaurantListView, self).get_context_data(**kwargs) context['order'] = self.kwargs['order'] return context I am trying to implement ReactJS into my front end. Currently, my template, restodetails.html has only a few CSS tags and no JS tag. I construct the entire page using just the template variables I have passed. But I can't see how I can integrate React into this. One way I got was to put React into a <script> tag in the head section, like here. But I'm keeping my React code in separate JSX files in the Django static folder, which I'm bundling using Webpack. I also don't like the idea of putting JavaScript into the template. Is there a way to pass those context variables into the JSX files? -
Celery Periodic Task not working on given crontab params

Django Rest Framework drop fields based on request url
