How can i add order detail to paypal smart button checkout
Hi i am building an ecommerce website with django and i was looking for a way to pass order details to the merchant account. I have tried this createOrder: function(data, actions) { return actions.order.create({ purchase_units: [{ amount: { value: '30.11', }, description: 'this is a description', }] }); }, this method worked but i can only pass strings. I have tried to pass lists but it didn't work createOrder: function(data, actions) { return actions.order.create({ purchase_units: [{ amount: { value: '30.11', }, description: [{ order: "dress5", price: "30" }] }] }); }, any recommendations on what i should do? -
Python, Django: Alternative to a raw-sql-query
Good evening, I would like to ask, if there's a different method to a raw sql query to update items by a certain condition inside my views.py? For example, I know I could do an insert query like this: models.py class Person(models.Model): name = models.CharField() age = models.IntegerField() value = models.IntegerField() views.py def something(request): ... qs = Person(name="John Doe", age=34, value=10) qs.save() ... Is there a similiar method for updating all "Persons" if they fit a certain condition? ... qs = Person("UPDATE Person SET value=5 WHERE age < 30") # or something like this qs.save() ... Thanks for all your help and advice and a great weekend to all of you! -
Custom threaded django comments - django.core.exceptions.AppRegistryNotReady: Apps aren't loaded yet
I am using django 3.1x and I'm following the example here to create a threaded comment app for my project. The article instructs to add the following lines to the __init__.py file so that django can use these hooks to lookup the altered models and forms and to overrides the default set. Here is the content of __init__.py: from models import MPTTComment from forms import MPTTCommentForm def get_model(): return MPTTComment def get_form(): return MPTTCommentForm The error message makes sense, because we appear to be importing objects that have not yet been created ... However, the author of the article states that it works - and none of the comments (granted, they are a year old) seem to be complaining of this issue. Am I missing something, or has the internals (loading sequence of django) changed? How do I fix this? -

django html template not loading from generic view from model
Introduction I am currently working on a small piece of the project to understand more about the Django ORM and to display individual objects. Using Generic views to keep the code clean. (I am somewhat new to Django Framework) Goal The goal of this piece is to show how many users have written an article. For example, I have total of 4 articles. I need to show how many articles written by each user. My console output: User Article Count testuser 2 testuser1 2 testuser2 0 my output on the HTML template: User Article Count testuser 0 testuser1 0 testuser2 0 Problem I am not understanding why my console output is correct, but my HTML template isn't showing the results. Please HELP me understand why it is doing this!!!!! If there is a similar post let me know! I have been looking everywhere for the answer, but I couldn't find it on the internet. Code views.py from django.views.generic import ListView from .models import Article from django.contrib.auth import get_user_model class ArticleListView(ListView): model = Article template_name = 'article_list.html' context_object_name='article_list' queryset=Article.objects.order_by('-date') def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) users = get_user_model().objects.all() context["users"] = users articles = Article.objects.all() for user in users: article_count = articles.filter(author__exact=user).values('author').count() … -
Dajngo Model embed multiple Abstract Models
Suppose I have an Order model for storing customers' orders on my site. There will be two address fields: shipping_address and billing_address. I could write it something like this: class Order(models.Model): order_number = models.CharField() time_created = models.DateTimeField() ... shipping_name = models.CharField() shipping_city = models.CharField() shipping_street = models.CharField() shipping_building = models.CharField() billing_name = models.CharField() billing_city = models.CharField() billing_street = models.CharField() billing_building = models.CharField() ... Then access fields by order.shipping_name and order.billing_name, but that is getting really cumbersome when every address needs to contain 15-20 fields. I tried One-to-One relationships, but code in other places of the application becomes very complicated. If there would be only one address field I could use an Abstract Model to make it a bit cleaner: class Address(models.Model): class Meta: abstract = True name = models.CharField() city = models.CharField() street = models.CharField() building = models.CharField() ... class Order(Address, models.Model): order_number = models.CharField() time_created = models.DateTimeField() But this way I can only have one set of address data and field names from the Address class would clash with fields from Order. Is there a way to inject or embed fields with given prefix in DB to given Model? I am looking for something similar to @Embedded decorator used … -

How to use Django channels to push newly created data to client side without reloading and not completely changing the existing normal view code
Hey guys I am quite new to django and django channels. I have a small doubt related to channels. For example, if I have a post model and I created a post, for the user to view the post, they need to either reload the page or we need to redirect them to the list page to view all the posts. What if I want to push the newly created post to the front end or to the client side without having them to reload the page? Can we use channels for that? And if we use channels for that purpose, do we need to rewrite all the codes we wrote in normal views or adding a snippet code like sending a signal when created and running an async function will do the trick? Is it difficult to implement? Thanks -

Django Login/Authenticate user by clicking email link?
Hey Everyone I am working on creating a custom EmployeeForm in which the form is for Business Administrators, to add employees. This creates a new user Account in the database. In order to give this employee access to the platform, a temporary unique password is also set for them. On creation, an email is sent to the new employees account email providing them with their email, and randomly generated password. I would like to also include a link to send them straight to the Change password view. With the click of this link, I want it to login the user, so that they don't have to go to the login page themselves, so that they are already authenticated/logged in, and all they have to do is type in their new password. I'm wondering if it is possible to log this user in automatically with the click of the "change password" link? I am also wondering if there is even a possible way to not even set a random password, and allow the user to just click the email link, and they are free to set their initial password themselves. (Note: password is not a required field, so the employee account … -
Is there a standard/commonly-used decision table library for python?
So here's the problem I'm having, and I'm sure it's a common one. I have a pre_save trigger set up for a model such that before a model instance is saved to the database, a series of checks and modifications are made to it depending on the characteristics of some of its fields, some aggregate values calculated with respect to other instances of the model and other models, and some threshold constants for the model. What I have right now works, but it is an ungodly mess of if-else statements that is completely unmaintainable. Obviously a decision table is required, but I can't seem to find anything besides the odd github project with only a few stars. Because of this I've made my own decision table class that seems to work on its own (yet to integrate into my project), but I'd much rather use something that has been widely tried and tested if it exists. Maybe there is something specific to django, that I've overlooked? Any suggestions would be greatly appreciated! -
Using DRF and React for Contact form
I haven't seen anybody accept the form like this using DRF. I'm practically listing all of the fields for the POST method. Is it safe to do so? class ContactForm(generics.ListCreateAPIView): queryset = Contact.objects.all() serializer_class = ContactSerializer @action(methods=['GET'], detail=True) def testing_env(self): return Response({'Works': 'ayyy'}) @action(methods=['POST'], detail=True) def create_contact(self, request): data = request.data print(data) contact = Contact.objects.create(name=data['name'], email=data['email'], subject=data['subject'], message=data['message']) contact.save() return Response({'Success': 'it went good'}) And here's the React Form: handleSubmit(event){ event.preventDefault(); let data = this.state axios({ method: 'post', url: FormURL(), data:{ name: this.state.name, email: this.state.email, subject: this.state.subject, message: this.state.message, } }) } -
Django Project DEPLOYMENT - SECRET KEY
I'm deploying a Django Project on pythonanywhere. This is my first time doing anything of this kind, and I forgot to delete the secret key of my project before pushing it to GitHub (my GitHub account is private), so now the secret key is available in the code in GitHub. Is that a big problem ('cause I still didn't understand what is the key used for)? Is there a way to fix this? I read some articles online and they suggest to keep the key in envoirment variable or stored in a file but I don't have any idea of how to do that or how to change the fact that now the key is available on my GitHub account and on python anywhere since I did git clone. Can someone help me please? -
how to customize a modelform for multiple question

How to deploy Django app with PostgreSQL on GCP at minimum cost for minimal server load?
I need to deploy a Django app using PostgreSQL as the database on Google Cloud Platform. Since the app is only for my personal use, it has a minimal server load. I tried a solution by deploying my app on an F1 App Engine standard environment(us-central1 region) and ran a PostgreSQL instance on an f1-small compute engine(us-central1 region). Both these are provided in GCP free tier in the us-central1 region. But it seems a VPC serverless connector is needed for app engine standard to access Postgres on compute engine on internal IP address.(which is billed as 2 e-2 micro instances). Is there a better way of deploying it on GCP or connecting App engine standard with compute engine private IP, which incurs lesser cost? -

unable to upload image to s3 from django app
