Function in Django model not updating and saving corresponding field
Trying to set-up a function inside the model below to count the length of an ArrayField whenever the instance is updated. The function def total_stocks_calc() doesn't update the model, it's useless. class Bucket(models.Model): stock_count = models.IntegerField(blank=True, null=True) stock_list = ArrayField(models.CharField(max_length=6,null=True),size=30,null=True, blank=True) objects = models.Manager() def total_stocks_calc(self): self.stock_count = len(Bucket.objects.get(self.id).stock_count) self.save() I'm not getting any errors as well, however this works in django shell: len(Bucket.objects.get(id=1).stock_count), I get the corresponding amount of items within the object. Would that be the best way to accomplish a Count or Length of total strings within the ArrayField known as stock_count? -
Trying to compare current time to expiration date and return true if within 7 days:
I am writing a Pantry Inventory app for a school project with a Django backend, a DjangoRest API and a Vue2 frontend. I am trying to discern if an item is within one week of the expiration date tied to each of the items, and change expiring_soon to true if it is. My model in Django takes the expiration date through a DateTimeField that is serialized as such: class PantrySerializer(serializers.ModelSerializer): owner_detail = NestedUserSerializer(read_only=True, source='owner') expiration_date = serializers.DateTimeField(format="%d-%m-%Y") class Meta: model = models.PantryItem fields = ( 'id', 'item_name', 'create_date', 'expiration_date', 'owner', 'owner_detail', 'getting_low', 'tag', 'category', 'quantity', 'to_grocery', 'slug', 'amount_type', 'expiring_soon', 'brand', ) After browsing some related questions I've tried this as a Vue method in my root app. I call it in the created section.: getExpiry: function() { var one_day=1000*60*60*24; var currentTime = new Date() for (let i = 0; i < this.pantryItems.length; i++) var exdate = this.pantryItems[i].expiration_date; var diff = Math.ceil((exdate.getTime() - currentTime.getTime())/one_day); if (diff <= 7) { this.pantryItems[i].expiring_soon = true updateItem() } }, gettingLow: function(item) { item.getting_low = true } It gives me this error: VM22198 vue.js:634 [Vue warn]: Error in created hook: "TypeError: Cannot read property 'getTime' of undefined" (found in <Root>) warn @ VM22198 vue.js:634 logError @ … -
Django Question - Should i start a new project in the same virtual environment?
Django newbie here. I have an existing Django virtual environment that was setup as part of a tutorial, using Django 2.2. and Vagrant + Virtual Box on my laptop. There was 1 project created for the tutorial above. I will now be starting another Django tutorial, wherein I will be creating a few more projects. WHat is the best way to go about this? Should I create a new virtual environment for tutorial #2? Or use the existing environment, that was setup for tutorial #1? FYI - tutorial #2 uses Django 1.11 Thanks a lot! -
Can't get the data from HTML page by using request.GET.get
I need a simple search form in my Django app. The code is: in HTML file: <html> <body> <h2><a href="/tube">Hypertube</a></h2> <a target="_blank" href="/login/"> Log In</a> <p><form action="tube/" method="GET"> <input name="q" placeholder="Search..."> <input type="submit" value="search"> </form></p> <p><a href="/tube/tag= {{ da_tag }}/">{{ da_tag }}</a></p> <p> {{ len }} videos</p> {% for video in videos %} <div><a href="/tube/watch/{{ video.id }}/">{{ video.video.title }}</a></div> {% endfor %} <p><a target="_blank" href="/tube/upload/">Upload video</a></p> </body> </html> in views.py: class MainPageView(ListView): def get(self, request): query = request.GET.get('q') if query is not None: videos = Video.objects.filter(Q(title__icontains=query)) else: videos = VideoTag.objects.all() return render(request, 'index.html', context={'videos': videos, 'len': len(videos)}) The problem is that 'query' is None.

Django request.user.id 'matching query does not exist' error in webhook
I'm building a Stripe webhook in my Django app that, after the payment is confirmed, retrieves the current user's ID in the database and uses it to assign a subscription to the team that that user is assigned to. There are a few database tables that are important to note here: User (a custom user model for my app) Team (an organization-style model table that contains team names and a ManyToManyField with the User table "through" to the Membership table) Membership (the "through" table that contains foreign keys to the user, team, and Stripe customer tables) StripeCustomer (the Stripe customer information table that has a OneToOneField with the Team table, and stores the Stripe customer ID and subscription ID) After the payment is confirmed in the Stripe webhook, I want to pull the current user's ID from the User table using request.user.id and use it with the Membership table to get an object containing the current user's team (so that the Stripe subscription can be assigned to that team). The problem is that, when I use request.user.id within Membership.objects.get(user_id=request.user.id), I receive an error in the console stating that the "Membership matching query does not exist." However, if I just print … -
Django error only when deployed on PythonAnywhere: "No category matches the give query"
I have deployed My Django website via PythonAnywhere.com and everything seems to be working other than my search bar which gives me the the following error even if the item does exist. You can reproduce the error by going to https://www.ultimatecards5.com/ and searching for anything in the search bar.

How can I add a second dependent field to my current Django dependent drop down form?(Car Makes/Models/Years
Context I'm currently building a car dealership app and am struggling on a dependent search form. At the moment, it takes the users make selection and returns a list of models belonging to it that exist in the db. However now I am struggling to make a second dependent field where available years are provided based on the model chosen. Attempts Made The question text will already be very long with just the Ajax but essentially, I've tried creating a duplicate Ajax request,view and url with slightly different names and targeting the carmodel but all I got was no errors and no results. I've tried rendering two dicts from the one request which did actually get me the years to log in the console but I couldn't join the two dicts successfully nor could I work out how to render the years when I got them to log. I went over everything line and understand when/how/why it's targeting certain id's and creating new options for the form but I just can't get it to work when the model is chosen after the make. Code Here is a view of my models.py class CarMake(models.Model): name = models.CharField(max_length=100) def __str__(self): return self.name … -

Django-import-export package post_save signal called twice
I am using the django-import-export package to import data from a model from the admin site. This model has a function for sending email that is executed with the post_save signal.

Django objects.get(): The QuerySet value for an exact lookup must be limited to one result using slicing
I'm trying to check if a user exists in the database based on email address, so I get the email and if that email exists, I want to return the username of that user alongside with some other data. I'm using objects.get() method to do so but I keep getting this error.

Is there a way to avoid CORS error while in production in NuxtJS?
I have been using NuxtJS locally alongside Django Rest Framework and there have been no issue. However, after deployment on Netlify I started getting CORS error - although, I have axios proxy set. I had to rerun npm run generate and run the generated file locally for which I get the same error. I later found out that proxy doesn't work with statically generated NuxtJS app. I have searched Google tirelessly but I can't seem to get a direct solution. I have to deploy this app on Netlify without having access to Nginx or Apache server. Please can anyone suggest a simple solution to avoid CORS error 405.
