How to integrate paypal in React Js with server side ( Django REST ) payment execution?
I am trying to integrate paypal in my application. My application has to be built using React JS and backend should be in Django. I have done the Client Side Integration using one npm package which is https://www.npmjs.com/package/react-paypal-express-checkout This is my code in React JS import React from "react"; import ReactDOM from "react-dom"; import PaypalExpressBtn from "react-paypal-express-checkout"; import "./styles.css"; function App() { const client = { sandbox: "AXMUBOcaszqCzfEOC-r--Rn7rMVoEbH9c6XbmyKb04nURqcLhpFxWwwnaUytaMR9UTaE2vwLfi5tqKbT", production: "" }; return ( <div className="App"> <h1>Hello CodeSandbox</h1> <h2>Start editing to see some magic happen!</h2> <PaypalExpressBtn client={client} currency={"USD"} total={500} onSuccess={(p) => console.log(p)} /> </div> ); } const rootElement = document.getElementById("root"); ReactDOM.render(<App />, rootElement); I am getting the following response { paid: true cancelled: false payerID: "TLCF8J8F3CZUY" paymentID: "PAYID-MAADRGI6U311288V5285313C" paymentToken: "EC-32J40105H07711055" returnUrl: "https://www.paypal.com/checkoutnow/error?paymentId=PAYID-MAADRGI6U311288V5285313C&token=EC-32J40105H07711055&PayerID=TLCF8J8F3CZUY" address: Object email: "sb-ueclm4695520@personal.example.com" } After the payment, also my sandbox account balance is been deducted. So this is working fine. But I want to do the payment execution securely in server side. How do i achieve it in Django? I have read the docs, they mentioned use SDK. So I have looked into the python sdk which is https://github.com/paypal/Checkout-Python-SDK from paypalcheckoutsdk.orders import OrdersCaptureRequest # Here, OrdersCaptureRequest() creates a POST request to /v2/checkout/orders # Replace APPROVED-ORDER-ID with the actual … -

In django, when user registered using CustomForm tries to login using Oauth
My Django app has an option for login/register using CustomForm (inherited from the UserCreationForm) as well as Outh. Now the problem is if a user has already signed up using the CustomForm and if the next time he tries to log in using google Oauth then instead of logging in, google Oauth is redirecting to some other signup form which looks like: But as the user is already registered, if he enters the same username/email here then it displays says username taken. So how can I resolve this issue? I mean I want the user to be able to use both custom form as well as Oauth, how can I implement that? My register function in views.py: def register(request): if request.method == 'POST': form = CustomForm(request.POST or None) if form.is_valid(): form.save() return redirect('login') else: return redirect('register') else: return render(request, 'accounts/register.html') forms.py looks something like this: class CustomForm(UserCreationForm): email = forms.EmailField() class Meta: model = User fields = ("username", "email") -

django: don't register ModelAdmin (exclude module-level code) when running makemigrations / migrate
I have made multiple changes to an existing django model (added new foreign key relation, etc). Before creating and applying these changes with manage.py makemigrations / migrate, I adapted the corresponding admin module's ModelAdmin for that app to reflect these unapplied changes. Running makemigrations now fails with "ProgrammingError: {new_field} does not exist". I figure this happens because when makemigrations runs system checks, the ModelAdmins in admin.py are registered (executing queries on non-existant models that I try to create with the migrations). Question: Is there any straight-forward way to exclude the ModelAdmins from being registered when running manage.py makemigrations / migrate without disabling system checks in total (see Django migration - disabel system checks)? I can solve the problem by deleting my admin.py modules when running makemigrations / migrate and recreating them afterwards. There is really no need to check the admin modules when migrating, but I guess this will happen when registering ModelAdmins on the module-level of admin.py (as in the examples in the django admin documentation). I do not use a custom AdminSite. On more general terms: is there any straight-forward way to exclude specific top-level module code from being executed when running a specific manage.py command like makemigrations … -

Notify user if data has changed since page loaded
I have 3 users that can view and commit changes to a database. Let's take for example an app called "personel". These 3 users can view the list of personel, edit personel data, and remove personel entries, from custom views. I am trying to solve this scenario: User A goes to /view_personel_list/ User B goes to /edit_personel/3/, and saves changes. User A is still viewing the non-updated personel list. I know this could be solved using AJAX, but I do not want to refresh. I am looking for a way to notify User A that the database has been changed. -

Heroku-deployed Django application does not appear in mobile browser
Situation: I've bought a specific domain, let's say 'example.ch' for my Django application which is deployed in Heroku. I also created an automated SSL certificate on Heroku (ACM). This certificate is valid for the WWW-subdomain, i.e. ACM Status says 'OK'. It fails for the non-WWW root domain, so I deleted the root domain entry on Heroku. I use 'swizzonic.ch' as webhostserver. Question: The redirection from 'example.ch' to 'https://www.example.ch' does not work on my mobile device, while everything is fine when I use my Mac and all common browsers. I found an older (unanswered) similar post to this topic (Django app on heroku: content wont appear in mobile browser). I don't know where to start, since seemingly nobody else faces this issue...

Any idea why this is happening? Like which part is causing this problem too, is it the function or my reverse lazy line? models.py class Comment(models.Model): post = models.ForeignKey(BlogPost, related_name='comments', on_delete=models.CASCADE) name = models.ForeignKey(settings.AUTH_USER_MODEL, related_name='name', on_delete=models.CASCADE) body = models.TextField() date_added = models.DateField(auto_now_add=True) class BlogPost(models.Model): chief_title = models.CharField(max_length=50, null=False, blank=False, unique=True) body = models.TextField(max_length=5000, null=False, blank=False) author = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) slug = models.SlugField(blank=True, unique=True) class Account(AbstractBaseUser): email = models.EmailField(verbose_name="email", max_length=60, unique=True) username = models.CharField(max_length=30, unique=True) forms.py class CommentForm(forms.ModelForm): class Meta: model = Comment fields = ['body'] widgets = { 'body' : forms.Textarea(attrs={'class': 'form-control'}), } views.py class AddCommentView(DetailView, FormView): model = BlogPost # change model to post because your are commenting on POSTS not COMMENTS form_class = CommentForm template_name = 'HomeFeed/add_comment.html' success_url =reverse_lazy('HomeFeed:main') def form_valid(self, form): comment = form.save(commit=False) #comment.user = self.request.user comment.name = self.request.user comment.post = self.get_object() comment.save() -

Why are the contents of my static css and js files being replaced by html code?
I have a pure js application from which I have generated the build files using yarn build I have the following files I now need to serve these files using Django. Here is what I have tried I have added a frontend folder in the Django app as follows I have also added the following URL re_path("wazimap/", TemplateView.as_view(template_name="index1.html")) and updated the settings file with the following TEMPLATES = [ { "BACKEND": "django.template.backends.django.DjangoTemplates", "DIRS": ["frontend/build/dist"], ....More code STATICFILES_DIRS = [ os.path.join(BASE_DIR, "static"), os.path.join(BASE_DIR, "frontend/build/dist"), ] now when I access the /wazimap/ URL, the HTML is served but the css/js that is being loaded contains the wrong code. I can see from the console that the files are being requested but index1.html is what is being placed inside all the css/js files i.e The contents of the css/js files are the content of the index1.html file. So a js file has something like <!DOCTYPE HTML>... which isn't a valid js thus causing errors. Any ideas why this is happening?
