How to optimize nested serializer custom update method
I'm writing a serializer that points to a nested serializer and as the documentation explains it is necesary to write custom create and update methods so that nested serializers could be writable. The way I'm doing this is next: def update(self, instance, validated_data): instance.attr1 = validated_data.get('attr1', instance) instance.attr2 = validated_data.get('attr2', instance) instance.attr3 = validated_data.get('attr3', instance) instance.save() return instance but the instance has 26 attributes. The question is. Is there a way of improving this code? -
Why is paddle.com overlay checkout not working from localhost?
I am trying to get a simple paddle.com overlay checkout working from a local hosted Django site - I'm using the sandbox for now. Currently I am just getting a "something went wrong" dialog when I try and open the checkout. I think I am following all the steps: I am including the following js in the webpage that is trying to show the checkout: <script src="https://cdn.paddle.com/paddle/paddle.js"></script> <script type="text/javascript"> Paddle.Environment.set('sandbox'); Paddle.Setup({ vendor: xxxx, }); </script> And then in the html later on in this page I have a button that I am pressing: <a href="#!" class="paddle_button" data-product="pri_xxxxxxxxxxxxx">Buy Now!</a> I have also set up the address in the sandbox checkout settings to be the url of the same page: https://localhost:8000/account/subscription When I press the Buy Now button I get the “something went wrong” dialog box coming up. I notice in Firefox developer console that it is trying to do an http get on: https://sandbox-create-checkout.paddle.com/v2/checkout/product/pri_xxxxxxxx/?product=pri_xxxxxxxxx&parentURL=https://localhost:8000/account/subscription&parent_url=https://localhost:8000/account/subscription&referring_domain=localhost:8000 / localhost:8000&display_mode=overlay&apple_pay_enabled=false&paddlejs-version=2.0.72&vendor=xxxxx&checkout_initiated=1695581565275&popup=true&paddle_js=true&is_popup=true And when I try and do a get on this link manually I get the following JSON back: {"errors":[{"status":404,"code":"error-creating-checkout","details":"Error creating the checkout"}]} I can also see a Cross-Origin Request Blocked error code in the console too – so I don’t know if that has something … -

Axios POST Request using JWT in Vue3 and Django
Alright so as the title says I have a working Django application where my API creates a JWT key and saves it to my cookies. Now my frontend which is in Vue is supposed to send a form to the backend which is supposed to generate the jwt key and set it to my cookies. How do I go about this. My apologies if the writing is a little crude, I have been troubleshooting this for well over 4 hours. It shows me a 403 Forbidden error on my console. Here's a snippet of my code for the frontend: try { const response = await axios.post('link/', UserData) const jwtToken = response.data.jwt Cookies.set('jwt', jwtToken) this.confirmed = true console.log(this.confirmed) } catch(error) { console.log(error) } Everything is imported as it should be. But this is the underlying code. the django app sends a response with the jwt code. while this is not secure, it is needed for the troubleshoot. Please what can i do -
