Writing correct views to display restaurant food menus
I am creating a webapp for a new restaurant and want to display the different food menus for people to view and owner to be able to update and delete items from the menu when appropriate. I have a model for the menus and the items on the menu """ A Menu represents a collection of categories of food items. For example, a restaurant may have a Lunch menu, and a Dinner menu. """ class Menu(models.Model): name = models.CharField(max_length=246, unique=True,) slug = models.SlugField(max_length=24, unique=True, help_text='The slug is the URL friendly version of the menu name, so that this can be accessed at a URL like mysite.com/menus/dinner/.') additional_text = models.CharField(max_length=128, null=True, blank=True, help_text='Any additional text that the menu might need, i.e. Served between 11:00am and 4:00pm.') order = models.PositiveSmallIntegerField(default=0, help_text='The order of the menu determines where this menu appears alongside other menus.') class Meta: verbose_name = 'menu name' def __str__(self): return self.name """ A Menu Category represents a grouping of items within a specific Menu.

Deployed Django project does not load static files
I have just deployed (first time ever) a Django project to a web server. Everything (including postgres) works flawlessly, except that static images won't load. Here is the relevant part of the settings.py: # Static files (CSS, JavaScript, Images) # https://docs.djangoproject.com/en/3.2/howto/static-files/ STATIC_URL = '/static/' STATIC_ROOT = os.path.join(BASE_DIR, "static/") #STATICFILES_DIRS = [ # os.path.join(BASE_DIR, "static"), #] # Default primary key field type # https://docs.djangoproject.com/en/3.2/ref/settings/#default-auto-field DEFAULT_AUTO_FIELD = 'django.db.models.BigAutoField' LOGIN_REDIRECT_URL = 'home' LOGIN_URL = 'login' LOGOUT_URL = 'logout' AUTH_USER_MODEL = 'account.CustomUser' MEDIA_URL = '/media/' MEDIA_ROOT = os.path.join(BASE_DIR, 'media/') The error message I get is the following in the console: "GET /static/images/logo.png HTTP/1.1" 404 1808 However, when checking the file path in the console I have the following: root@melius:/django/melius/static/images# In this folder the files are present.

How do I check if there are items in the database Django
Disclaimer, I've just started with Django a couple of days ago so I'm still quite new to it, patiance please. Alright so I have two different models in my models file. One of them is the Order with certain order attributes and the other one is Counter, an assistant model so to say. The idea is that I need to check the database if an order exists, if it doesn't, i need to give Counter the value of 1 as this will be the first order, then the value needs to be assigned to the code of the Order model. On the other hand, if an order does exist, then increment a counter by 1. Here's my approach and it's getting me this error as the value of code: <django.db.models.query_utils.DeferredAttribute object at 0x04996280> Here is the simplified version of the models. Also quick question, am I right to do this part on the models file? Should I do it on the serializer or views or it doesn't really change anything. Thanks in advance. class Counter(models.Model): def count(self): self.value = 0 for order in Order.objects.all(): self.value += 1 return self.value @property def names(self): return "P+ %s + %s" % (self.value, Order.code_year) … -
Django Remote User Authentication
I am using Django to build a data analysis webpage for our corporate. Currently, I am using the default Django server as the domain of my webpage. However, I am new to Django. In the webpage I want to do two things: In the navigation bar on the website, I want the username shown. Anyone using the corporate network or in the Active Directory of the corporate is authenticated to use the webpage, and once they visit it, their username is shown at the top of the page. I want to embed a Spotfire file in the webpage. However, I don't want the embedded Spotfire to ask for login, I want it directly shown to the user. I hope you can help me. -

Django Error on Form instead of raising a ValidationError
I was wondering how I could show an error on the form instead of raising a validation error page. I mean when on the form itself the errorlist is generated, I will attach a screen shot of a different form because my explanation isn't the best haha. Right now in my view I raise a ValidationError instead of the form just adding the error itself. How can I go about adding the form error instead of raising an actual validation error? I would like the normal behavior of errorlist appearing on my form. Any help is greatly appreciated! my view is as follows: class EditProfileInformationView(LoginRequiredMixin, View): def get(self, request, *args, **kwargs): form = UserEditForm(initial={ 'first_name': self.request.user.first_name, 'last_name': self.request.user.last_name, 'email': self.request.user.email }) context = { 'form':form } return render(request, 'accounts/update.html', context) def post(self, request, *args, **kwargs): form = UserEditForm(instance=request.user, data=request.POST) context = { 'form': form } if form.is_valid(): initial_email = self.request.user.email form.save(commit=False) email = form.cleaned_data['email'] if User.objects.filter(email=email).exists() and email != initial_email: raise ValidationError('This email already exists') else: form.save() messages.success(request,'Profile Successfully Updated') return redirect('/') else: return render(request, 'accounts/update.html', context) -
How to get the nth record of a model with Python - Django?
I'm currently working on a command that deletes old records for some models that grow a lot in the database. The idea behind is receiving a parameter that indicates from which record number (not id) we have to delete backwards. For doing this i came up with this solution: reference_record = WarmUpCache.objects.filter(company_id=company).values_list('id', flat=True).order_by('-id')[_number_of_records] records_to_delete = WarmUpCache.objects.filter(company_id=company,id__lt=reference_record) if records_to_delete: records_to_delete.delete() For example, for a given company_id=118 I get the ids of the records associated to that Company. Having this, I try to get the nTh record and then, calculate how many records are with an id lower than the given one. After that, delete all of them. Currently this solution is working, but I'm managing to improve it somehow. I have checked stackoverflow to find any answers but I only found old answers that explain almost the same solution I made: django query get last n records django queryset runtime - get nth entry in constant time So, the question itself is ¿Is there any way to improve this query by obtaining just the nth record of a model? Thanks a lot. -

Launch login modal on page load
I'm creating a Django based site and want to launch a login modal if a user tries to access a restricted page while unauthenticated.

DRY principal in django for needing to use the same query in every function
I have a question. I have a django project where I inherit a navigation bar in all my rendered html views. I want to pass a variable that records how many of certain instance exisits within my DB. Okay so this is extremely simple if I write a query in every single function that renders an html page that {%include 'partials/navbar.html'%}, and every function does because I extend my index file which includes my navbar So like I said it super simple to write a query within every single function and then pass this value in the context. But is there a way that is less tedious almost like an injector in angular?enter image description here -

Received not compatible Decimal
I am trying to add data to the Loan model using django-graphene mutations but I am receiving this error as mentioned below. My code is as follows. models.py class Loan(models.Model): principle = models.DecimalField(max_digits=8, decimal_places=2) tenure = models.PositiveSmallIntegerField(help_text="Duration in months ") mutation.py # making a DjangoObjectType of Loan Model class LoanType(DjangoObjectType): class Meta: model = loan_model # create new Loan class LoanMutation(graphene.Mutation): class Arguments: # The input arguments for this mutation principle = graphene.DecimalField() tenure = graphene.Int() # loan endpoint loan = graphene.Field(LoanType) @classmethod def mutate(cls, root, info, principle, tenure): loan = loan_model(principle=principle, tenure=tenure) loan.save() # Notice we return an instance of this mutation return LoanMutation(loan=loan) class Mutation(graphene.ObjectType): new_loan = LoanMutation.Field() schema = graphene.Schema(query=Query, mutation=Mutation) GraphiQL mutation i tried to execute mutation CreateLoan { newLoan(principle: 300.50, tenure: 12) { loan { id principle tenure } } } response i received { "errors": [ { "message": "Received not compatible Decimal \"300.5\"" } ], "data": { "newLoan": { "loan": null } } } I have tried to use principle = models.FloatField() and principle = graphene.FloatField() i do not receive this error.
