Assigning a datetime object as the url parameter
I want to give the value of Datetime type to url as parameter using date filter. My url must be such: /account/detail-of-cash-flow/2020-8-10 This command: {{item.date_field|date:'Y-m-d'}} = '2020-8-10'. But, not working when i this commands implement to template url. template.html {% for item in cash_flow_data %} <tr class='clickable-row' data-href="{% url 'account:detail_of_cash_flow' item.date_field|date:'Y-m-d' %}"> <td>{{ item.date_field }}</td> <td>{{ item.EUR }}</td> <td>{{ item.USD }}</td> <td>{{ item.GBP }}</td> <td>{{ item.TRY }}</td> </tr> {% endfor %} urls.py app_name = "account" urlpatterns = [ path('daily-cash-flow/', views.daily_cash_flow, name = "daily_cash_flow"), path('detail-of-cash-flow/<slug:slug>/', views.detail_of_cash_flow, name = "detail_of_cash_flow") ] I hope I was able to explain my problem. -
Batch loading with Pygrametl
right now i'm using a fact table that insert in to the database one row at a time using pygrametl like the two snippets below: self.targetconnection = Etl_Common.get_database_connection(settings.DATAMART_DATABASE) self.fact_table = FactTable( name='fct_efficency', keyrefs=( 'key', ), measures=( 'measure_1' 'measure_2' ), targetconnection=self.targetconnection, ) def insert_measure_data( self, key, measure_1, measure_2, ): row_dict = { 'key': key, 'measure_1': measure_1, 'measure_2': measure_2, } try: self.fact_table.insert(row_dict) except Exception as exc: logger.error('got exception {}'.format(exc)) The problem with this solution obviusly is that if i try to insert lots of rows it takes ages to put all data into the database. Looking at the pygrametl documentation i found a very fitting solution for my problem : BatchFactTables. the problem is that following the documentation i couldn't find an example to follow regarding the insertion of multiple lines togheter... is there any guide/snippet i could use as a guide for my problem? many thanks -

Cannot log in to admin site with superuser account, which was created with console // Django

Get id of an looped in html element
{% for product in products %} ... <form class="form-inline"> <div class="input-group"> <input type="hidden" name="productId" id="productId" value="{{product.id}}"> <input type="text" class="form-control" name="productQuantity" id="productQuantity" style="width: 40px; height: 40px;" placeholder="1"> <div class="input-group-append"> <button type='button' name="addToCart" id="addToCart" value="+" class="btn btnother"><i class="fas fa-plus fa-sm" style="color: white;"></i></button> </div> </div> </form> ... {% endfor %} This is a simplified code! So I have an e-commerce Django website. On the main page I represent cards of different products with possibility of adding them to cart. Every time someone adds item to a cart, I want to only update cart image in header. So I want to use AJAX to pass productId and productQuantity to my views.py. Here is my JS: $(document).ready(function(){ $('form').click(function() { var productId = $('#productId').val(); var productQuantity = $('#productQuantity').val(); if (Number.isInteger(Number(productQuantity))){ productQuantity = productQuantity; } else { productQuantity = 1; } $.ajax({ url: 'update', type: 'post', cache: false, data: { 'productId' : productId, 'productQuantity' : productQuantity } }); }); }); However, when I add to cart, the productId being printed is the same for all products. I think it is because after the for loop it stores only the last productId What would be a way to get the id of every individual element? -
AJAX GET request is not showing an error in console but also not firing
I have a bit of an issue I'm hoping some fresh eyes can help with. I have an ajax get request that is supposed to pull some data from my database via Django views class and then display it on an html page. After doing a bit of debugging I've gotten it to the point where it is not throwing an error, however it is also not providing any data now. I'm wondering if someone could have a look and offer some feedback? Here is the AJAX request $(document).ready(function(){ console.log('Document Ready') $.ajax({ type: "GET", url : '/electra/playlist/', dataType: "json", //contentType: "application/json", data: { 'venue': 'venue', 'list': 'list', }, success: function(data){ $("#cafe-playlist").html(data); console.log(data) }, failure: function(errMsg) { alert(errMsg); } }); }); Here is the urls: urlpatterns = [ [...] path('electra/playlist', views.user_playlist.as_view()), Here is the views.py class user_playlist(ListView): template_name = 'testingland/dashboard.html' context_object_name = 'playlist' model = UserVenue def get_queryset(self): venue_name = self.request.GET.get('venue', None) list_name = self.request.GET.get('list', None) return UserList.objects.all() Here is the html template <body> {% block content %} <div class="container-fluid" style="padding:15px"> <!--location --> <div class="row"> <div class="col-sm-3" id="playlist"><p>Lists</p> <ul id = "cafe-playlist"> {% for item in playlist %} <li> <div> <h6 class="playlist-name">{{ item.list }}</h6> </div> </li> </div> {% endfor %} {% … -
Django: Duplicated logic between properties and queryset annotations
When I want to define my business logic, I'm struggling finding the right way to do this, because I often both need a property AND a custom queryset to get the same info. In the end, the logic is duplicated. Let me explain... First, after defining my class, I naturally start writing a simple property for data I need: class PickupTimeSlot(models.Model): @property def nb_bookings(self) -> int: """ How many times this time slot is booked? """ return self.order_set.validated().count() Then, I quickly realise that calling this property while dealing with many objects in a queryset will lead to duplicated queries and will kill performance (even if I use prefetching, because filtering is called again). So I solve the problem writing a custom queryset with annotation: class PickupTimeSlotQuerySet(query.QuerySet): def add_nb_bookings_data(self): return self.annotate(db_nb_bookings=Count('order', filter=Q(order__status=Order.VALIDATED))) The issue And then, I end up with 2 problems: I have the same business logic ("how to find the number of bookings") written twice, that could lead to functional errors. I need to find two different attribute names to avoid conflicts, because obviously, setting nb_bookings for both the property and the annotation don't work. This forces me, when using my object, to think about how the data is … -

How do I re-run npm build in React and Django?
So I'm learning React and Django, and executed npm run build to run the React App in my Django server (port 8000). Then I turned the React app off(ctrl+C), and now I'm trying to run it again.

How do I get data from a form while the user is typing in his data? Django/Python
I have a problem I am currently working on. Really new to django and python. What I am trying to do is I have a form where the user can rent a parking lots for a certain period of time. I want to be able to dynamically calculate the value of the price based on the time the user selects and show this to the user. Meaning that price x time selected will generate a price that the user should be able to see. I do have the view ready and started with a function to calculate the price, but I got stuck really fast since I can't come up with how to get the user input data before the form, where the data is entered, is submited. Below you see the view i wrote to this: def list_parking_lots(request): """ View for all parking lots :param request: request from user :return: rendered parking_mgmt/list_parking_lots.html """ parking_lots = ParkingLot.objects.all() form = ReservationForm() if request.method == 'POST': form = ReservationForm(request.POST) if form.is_valid(): form.save() messages.success(request, 'Your reservation was successfully registered.') form = ReservationForm() return render(request, 'parking_mgmt/list_parking_lots.html', {'parking_lots': parking_lots, 'form': form}) Any help is appreciated. -
