How to group by json field data in django-mongodb
Hi, Thanks in advance... I am using Django 3.0.5, Python 3.8.0, and MongoDB 5.0 My requirement: Group the data by matching the value of Width, Height, Thickness, and Type fields. While grouping the data, do the summation of Length. I tried this way list(UploadCableTrayData.objects.filter(creator_id__in=selected_users).filter(date_added__range=(selected_start_date, selected_end_date)).values( 'Thickness__value', 'Width__value', 'Height__value', 'Selection').annotate(dcount=Count(['Thickness', 'Width', 'Height']), Length=Sum('Length__value')).order_by("date_updated")) But I am getting errors like this NameError: name 'Thickness__value' is not defined Here is my model class UploadCableTrayData(BaseModel, models.Model): """ Model to store Cable Tray data """ order_upload_id = models.AutoField(primary_key=True) Order_number = jsonfield.JSONField(null=True, blank=True) Type = jsonfield.JSONField(null=True, blank=True) Selection = jsonfield.JSONField(null=True, blank=True) Height = jsonfield.JSONField(null=True, blank=True) Width = jsonfield.JSONField(null=True) Box_width = jsonfield.JSONField(null=True) Box_height = jsonfield.JSONField(null=True) Length = jsonfield.JSONField(null=True) Inner_bend1 = jsonfield.JSONField(null=True, blank=True) Inner_bend2 = jsonfield.JSONField(null=True, blank=True) Thickness = jsonfield.JSONField(null=True, blank=True) Rung_width = jsonfield.JSONField(null=True, blank=True) Rung_height = jsonfield.JSONField(null=True, blank=True) Distance_between_rungs = jsonfield.JSONField(null=True, blank=True) project = models.ForeignKey('project.Project', on_delete=models.DO_NOTHING) def __str__(self): return str(self.order_upload_id) class Meta: db_table = 'UploadCableTrayData' Data stored in the model is like this { "_id": { "$oid": "62384f772d6545101709083b" }, "order_upload_id": 4, "creator_id": 3, "updater_id": 3, "date_added": { "$date": { "$numberLong": "1647857527370" } }, "date_updated": { "$date": { "$numberLong": "1647857527370" } }, "is_deleted": false, "Order_number": { "key": "order", "value": "o1" }, "Type": { "key": "type", "value": "pct" }, … -

External URL into a iframe to embed an external url within Django
I would like to embed a pptx that is uploaded into a folder in OneDrive within a iframe tag in a Django template. I have the urls stored in a model and saved into the SQLite database. In this sense, in the views.py file, I have the following code: context = { 'selectedunit': selectedunit, 'url_to_be_inserted': MyModel.objects.filter(unit=selectedunit) } return render(request, 'web.html', context) The code for web.html is very easy: {% extends 'base.html' %} {% load static %} {% block content %} <div class="container col-lg-8"> <div class="center"> <iframe class="center" src={{ url_to_be_inserted.url }} width="100%" height="300%" frameborder="0"/> </div> </div> {% endblock %} The result is the snapshot below: While, I would like to embed the ppt into the web site. If I directly insert the URL, instead of using the context variable, it works. That is to say: <iframe class="center" src="https://..." width="100%" height="300%" frameborder="0"/> In this case, the result is as follows (ppt embedded into the Web site): The reason why doing in this sense is because, depending on the selectedunit variable, I would like to address a different pptx with a different URL and I would like to dynamically change the pointer (as you see above by filtering the model). How could I … -
Is there a better way to dynamically change the content of a div in django othen than AJAX?

Django-filters query params conflict
I am trying to work with filtering db by query params from the link that looks like this: {{url}}/api/books?author="XXX"&from=2003&to=2051&acquired=true I already handled author and acquired params but am stuck with from and to. My filter.py looks like this: class BookFilter(django_filters.FilterSet): author = django_filters.CharFilter(field_name="authors__fullname", lookup_expr="icontains") from = django_filters.NumberFilter(field_name="published_year", lookup_expr="gte") to = django_filters.NumberFilter(field_name="published_year", lookup_expr="lte") acquired = django_filters.BooleanFilter(field_name="acquired") class Meta: model = Book fields = [ "author", "from", "to", "acquired" ] I am looking for a way to assign these query params without overwriting key words (from and to) which is obviously a terrible idea. -

Reading from excel in python when cells have multiple operations
I am currently doing a project where all computations are done in excel i have multiple references and if conditions, the output of all of this is a number. The input is computed in python, it carries the information to the excel which has all the formulas to compute the output. I am trying to use the openpyxl library to get this value into my python programm, the written input works well but the last computed number that needs to be extracted as the result or output of the excel is not being done correctly. The output gives the operation not the result of the operation. I have tries using the data_only=True but does not work and the xlwings library solution dies not work either. I just need a command that once I introduce the input, executes all excel operations so that I can extract the result onto my python programm. ¿how can i do this? -
Django overriding get_context_data() not rendering in template
I'm relatively new to Django and I'm learning to work with CBV's and I am currently working on a simple todo list, I want to get specific user data for specific users. The way I am doing this is by overriding the get_context_data() method in my ListView class, but the data is not showing in my template. I have created multiple users and created multiple tasks, but still does not work even though I can access them through the admin page. Here is my code: views.py: class TaskList(LoginRequiredMixin, ListView): model = Task template_name = 'app/home.html' context_object_name = 'tasks' def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) context['tasks'] = context['tasks'].filter(user=self.request.user) context['count'] = context['tasks'].filter( complete=False).count() return context urls.py: from django.urls import path from .views import ( TaskList, TaskDetail, TaskCreate, TaskUpdate, TaskDelete, UserLogin, UserLogout ) urlpatterns = [ path('login/', UserLogin.as_view(), name='login'), path('logout/', UserLogout.as_view(), name='logout'), path('', TaskList.as_view(), name='home'), path('task-detail/<int:pk>/', TaskDetail.as_view(), name='task-detail'), path('task-create/', TaskCreate.as_view(), name='task-create'), path('task-update/<int:pk>/', TaskUpdate.as_view(), name='task-update'), path('task-delete/<int:pk>/', TaskDelete.as_view(), name='task-delete') ] home.html: <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>To Do List</title> </head> <body> {% if request.user.is_authenticated %} <p>{{ request.user }}</p> <a href="{% url 'logout' %}">Logout</a> {% else %} <a href="{% url 'login' %}">Login</a> {% endif %} <hr> <a href="{% url 'task-create' %}">Add Task</a> <table> <tr> … -

Could I use memcached as a channel layer in Django?
I would like to use Django Channels in my application and I need a channel layer but I don't want to use Redis because, it is not available in my hosting plan. I have to get a dedicated or VPS server and I'm not ready for this yet. Instead, Memcached is available. I have searched the documentation of channels and Django and the internet I found nothing about it. But I know that before Redis, Memcached was used to implement the same. Basically I would like to configure my settings.py like that CHANNEL_LAYERS = { "default": { "BACKEND": "channels_mencached.core.MemcachedChannelLayer", "CONFIG": { "host": "amqp://guest:guest@127.0.0.1:5672/", }, }, } This is really a pseudocode, in reality I have no idea about how to configure Django for Memcached. I know Memcached is not officially supported but, is there a way to hack it and make it work on Django? If not, is there any alternative to be used in production, aside from Redis and RabbigMQ? -
