Is it possible to add a new data on Django Object in view?
My question is only to ask if this is possible. For example this QuerySet in view: item_list = ItemList.objects.all() Inside item_list, I want to add an HTML tag to be rendered to template. html_var = "<div> SOMETHING </div>" item_list = item_list + html_var or something Reason: I want to control what type of html tag based on the index of the item_list. My first option was to use modulus on loop counter but based on docs and other's comment, we can't get the remainder on the modulus operator. The return is a boolean. If you have other suggestion instead please let me know. Result that I want: If index/forloop.counter0 of item_list's modulus of 4 equals 1, <div class="upper-left"> If index/forloop.counter0 of item_list's modulus of 4 equals 2, <div class="lower-left"> If index/forloop.counter0 of item_list's modulus of 4 equals 3, <div class="upper-right"> If index/forloop.counter0 of item_list's modulus of 4 equals 0, <div class="lower-right"> -
Django: Model.objects.filter() returns an empty Queryset
I am using Django for the Backend in my webapplication. I have a some data in my database which I can query just fine with the objects.get() method. volumes = Volume.objects.get(volumeEngTitle="If there is a volume Title") This returns the following value in Postman: { "volumeNumber": 8.1 "chapterNumber": 12 "Translated": True } But I need to return multiple volumes that have the same title. This is why I tried to use filter() but the result of the Http.Get in Postman is always an empty set, e.g {}. filter() seems to never find any instance that matches the volumeEngTitle even though it exists. Here is the whole function to return the volume. from rest_framework.response import Response from .serializers import VolumeSerializer from ..volumeModel import Volume @api_view(['GET']) def getVolume(request): volumes = Volume.objects.filter(volumeEngTitle="If there is a volume Title") #This works like a charm but only for a single instance: #volumes = Volume.objects.get(volumeEngTitle="If there is a volume Title") serializer = VolumeSerializer(volumes) return Response(serializer.data) The result of this method is always {}. Even though it works fine with the get() method. I understand that get() is for a single return value and filter() gives me a queryset with mulitple values. But I can't figure out why filter … -

Django: manytomany relations not loaded even it exists
We run a Django server for an ecommerce web, where thousands of queries are made, and lastly we're getting many errors like: "FieldError: Cannot resolve keyword 'stockrecords' into field. Choices are: ..." I know that this error is thrown whenever we're trying to join a table through a field that doesn't exist in the model, but it really does exist. The definition of the model StockRecord is: class StockRecord(models.Model): product = models.ForeignKey( 'catalogue.Product', on_delete=models.CASCADE, related_name="stockrecords", verbose_name=_("Product")) num_in_stock = models.PositiveIntegerField( _("Number in stock"), blank=True, null=True) And the definition of the product does not include any reference to the stockrecords. And the errors is produced when calling: class ProductQuerySet(models.query.QuerySet): def with_stock(self): return self.filter(stockrecords__num_in_stock__gt=0) Where 'self' is a product.

How to use the pool connections set up with django-postgrespool2 when querying the database?
I have just set up django-postgrespool2 for creating a connection pool between my Django and PostgreSQL database. I followed the readme guide here on how to install and config it. It works now and I can run my project with django-postgrespool2. However, here comes my question. How do I verify that the pool connections are being used when I query the database?

Open source cryptography based software licence creation in python
I'm working on a server-side (Django) implementation for issuing licenses to on-premise nodes as a response to renew license API call. These licenses will have a short expiry forcing end-user to provide internet to on-premises nodes in order to continue operations. I'm looking for a mechanism to create license certificates with short expiry (7 days) on an authenticated API call. Renewed certificate will allow Python web app running on-premises Linux OS to operate seven more days. This will force the end-user to provide internet access so that the server can collect compiled data from nodes. A crypto algorithm will create a private key from the node’s UUID (dmidecode). The server will have private keys for all registered nodes to sign license certificates with seven days expiry. Python web app will verify certificate expiry using the system’s UUID at each startup. A simple way to do this would be to use JWT for certificates creation and UUID as secrete keys but I want to know if there are any open-source lib specialized for this case or is there any other better way to implement this. Note: Linux Node is shipped to the end-user preconfigured with an encrypted drive so users do … -

Date format inconsistency in Django Model

How to properly show image stored from a file server to a django HTML template?
I have trouble displaying images stored in a file server to the django template. File server link is \11234.123.123.123\dashboard.jpg (just a sample).

But, the image does not show properly as follows. Please help, thank you! -
How can I retrieve form data out of request.POST in Django
I want to get a form data sent through request.POST. The data is in a form of dictionaries inside a list. Here is the html form and ajax request: <form class="passwordUpdateForm" novalidate="" name="passwordUpdate" action="" method="" id="passwordUpdateForm"> {% csrf_token %} <div class="md-form md-outline mb-3"> <label data-error="wrong" data-success="right" for="oldPass">current password </label> <input type="password" id="oldPass" class="form-control" name="oldPassword" placeholder="*********" value=""> </div> <div class="md-form md-outline mb-3"> <label data-error="wrong" data-success="right" for="newPass">new password </label> <input type="password" id="newPass" class="form-control" name="newPassword" placeholder="*********" value=""> </div> <div class="md-form md-outline mb-5"> <label data-error="wrong" data-success="right" for="newPassConfirm">confirm new password </label> <input type="password" id="newPassConfirm" class="form-control" name="newPasswordConfirm" placeholder="*********" value=""> </div> <button type="submit" class="btn btn-primary mb-4"> change password </button> </form> <!-- to change user password --> <script type="text/javascript"> $('#passwordUpdateForm').on('submit', function(event) { event.preventDefault(); // to get form data var formData = $(this).serializeArray(); var formData = JSON.stringify(formData); alert(formData); // submit ajax request $.ajax({ type: "POST", url: "{% url 'passwordReset' %}", dataType: "json", contentType: false, processData: false, data: { 'form_data': formData, csrfmiddlewaretoken: '{{csrf_token}}', }, success: function(data) { data = JSON.parse(data); var message = $('#flashMessage').html(''); message.append('<div class="alert alert-warning alert-dismissible fade show" role="alert">'+'<strong>'+'sorry {{first_name}} </strong>'+ data +'<button type="button" class="close" data-dismiss="alert" aria-label="Close">'+'<span aria-hidden="true">&times;</span>'+'</button></div>'); } }); }); </script> The backend view function is as follow: def passwordReset(request): # process form data if request.method == …
