Django how to model.filter(value__istartswith__in=['xx','YY'])

IGNORA = ['xx','yy.', ] # something like this model.filter(value__istartswith__in=IGNORA) def check_code(codice): for x in IGNORA: if codice.startswith(x): return True return False Can it be done someway? -
What are the parsers used for in the Django Rest Framework?
I have a simple file model class Documents(models.Model): """ uploaded documents""" author = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) upload = models.FileField(storage=PrivateMediaStorage()) filename = models.CharField(_('documents name'), max_length=255, blank=True, null=True) datafile = models.FileField() created = models.DateTimeField(auto_now_add=True) type = models.ForeignKey(Doctype, on_delete=models.CASCADE, blank=True) To display the list of uploaded documents and add new files, I use the class class DocumentsListView(viewsets.ViewSetMixin,generics.ListCreateAPIView): queryset = Documents.objects.all() serializer_class = DocumentsSerializer def perform_create(self, serializer): serializer.save(author=self.request.user) serializer.py class DocumentsSerializer(AwsUrlMixin, serializers.ModelSerializer): type_name = serializers.CharField(source='type.type', read_only=True) type = serializers.PrimaryKeyRelatedField(queryset=Doctype.objects.all()) view_file = serializers.SerializerMethodField() author = serializers.CharField(source='author.username', read_only=True) created = serializers.DateTimeField(format=date_format, input_formats=None, default_timezone=None, read_only=True) class Meta: model = Documents fields = ('id', 'author', 'filename', 'datafile', 'type', 'type_name', 'created', 'view_file') I use the standard DRF interface and I display everything normally and add new files to the database. While reading the documentation I came across parsers such as MultipartParser, FileUploadParser, which are also used when adding new files. I can't underatand when to use them and what function they perform, because now everything works without them. The documentation hasn't given me a clear understanding of when I need to use parsers. I try to add parser_classes = (MultiPartParser, FileUploadParser) to serializers.py and nothing change. Everything works as it did before. I'd appreciate it if you'd make that clear … -
Python Beam Analysis on web (FEM / FEA)
For my uni project, i am to code a beam shear force and bending moment calculator using the direct stiffness matrix method. I have done the backend code on python to calculate the needed shear force and bending moment diagrams. I am quite new to programming so I would like to know how to deploy the python code onto a website. Should I use Django/ Flask or anything else. The aim is for an input web app like this: https://beamguru.com/online/beam-calculator/ Apologies if it's a stupid question. -
Turn shell output into method for Django model
I am trying write a method for one of my models, that will end up with a list of boolean values based on a manytomany field. So I am looping though category id's and comparing them with a queryset, but I can't work out how to translate what I get in the shell to a function. I've been struggle with OOP for about 3 years now, which is why I started learning django in the first place. but basically, in the django shell, I can do this to get the queryset I want: p1 = Project.objects.get(id=2) p1.update_categories.all().values_list('id', flat=True) The problem I have is that this is for one project and I can't figure out how you translate that into something that will work for all instances. So far I have this: def checkmark(self): ''' Generates a list of True or False based on many to many field for Project and UpdateCategory ''' checkmark = [] # This is the line giving me issues queryset = Project.objects.filter(project=self, update_categories) # this bit all works fine categories = UpdateCategory.objects.all().values_list('id', flat=True) for cat_id in categories: if cat_id in queryset: checkmark.append(True) else: checkmark.append(False) return checkmark So what I am doing here is creating an empty … -
Can I put 2 models in a single class in Django Views.py?
Objective: I'm trying to display products and orders from 2 different tables in a template. I'm having difficulties on how can I possibly join two models in 1 class in views.py. I have tried django rest framework but that's not the scope of my app. Here is my code: class UserDashboardTemplateView(ListView): #I want to insert the ORDER model in this class also model = Product context_object_name = 'product' template_name = 'product/dashboard.html' The data must be displayed in this format: {% for o in orders %} <tr> <td>{{ o.status }}</td> </tr> {% endfor %} -
Django-Q set Q_CLUSTER 'sync': True doesn't work for unit tests
I am using Django-Q to send async emails with Django 2.2, DRF 3.9 and Postgres 10.9 The setup works fine except when it comes to unit tests. I refer to the following issue which is the exact same thing I am facing: https://github.com/Koed00/django-q/issues/266 As per the link, one of the solutions was to do change the sync setting to 'True' for testing purposes. This is what i have in tests.py: from django.conf import settings settings.Q_CLUSTER['sync'] = True class UserAPITestCase(APITransactionTestCase): print(settings.Q_CLUSTER) 'print' shows that the 'sync':True has been added, but the async_task still runs in async mode. However if I were to add the sync setting in the settings file directly everything works as it should and the async_task runs synchronously. It's like django-q isn't taking in the setting if it is updated later. How do I fix that? -

Passing a username from django login to angular navbar
I am using django login template as the first page a user will see, upon successful login they will then be on the angular side because of the <app-root> tag in my django home template. I have a navbar component in angular and I would like to display the users name and give them an option to logout. I can see it is getting the name correctly as it shows if I have it before the <app-root> tag. I am currently trying to pass {{user.username}} into the <app-root> tag and then eventually through to the navbar component but nothing appears on the navbar. Django Template: {{user.username}} //this bit shows the correct name <app-root [theUser] = "{{user.username}}"> <div class="container-fluid"> <div class="row align-items-center"> <div class="col text-center"> <div class="spinner-border p-5 m-5" role="status"> <span class="sr-only">Loading . . .</span> </div> </div> </div> </div> </app-root> app.component.html: <app-nav-bar [theUserName]="theUser"></app-nav-bar> nav-bar.component.html: <h4>{{theUserName}}</h4> I expected the username to be passed through the angular components and be displayed on the navbar. There is nothing being displayed, I can see the h4 is empty on dev tools. -

How to filter case-insensitive on oneToOneField in django
I'm trying to filter case-insensitive on the auth_user model which has a oneToOne relation with my model as shown in code beneath. class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) headline = models.TextField(max_length=120, null=True) Normally to filter case-insensitive '__icontains' does the job, however if I filter with the following code, it is still case-sensitive even though I used icontains. profiles = profiles.filter(Q(user__first_name__icontains=search) | Q(user__last_name__icontains=search)).order_by('-id') I think the problem is with using 'user__first_name' since it is a field of a module related to profile and filtering on 'headline' which is a direct field of profile can be done case-insensitive. Any idea what the best solution is for this problem? -

Dymaically generating form choices from db content
Using rest frameworks serializers and renderes, I want to generate a html radio button input that takes its choices from a field in the database. For example, given I have "A", "B", and "C" as content of an organizations model, I want a from with these three choices as radio buttons. Can you use standard model serializers to do this?
