i want to make menu dropdown react js django in section (salary)
I'm trying to menu dropdow reactjs django in the section formgroup (salary): and this is the source code from [github] https://github.com/diogosouza/django-react-logrocket import React from "react"; import Select from 'react-select'; import { Button, Form, FormGroup, Input, Label } from "reactstrap"; import axios from "axios"; import { API_URL } from "../constants"; class NewStudentForm extends React.Component { state = { pk: 0, name: "", address: "", role: "", department: "", salary: "" }; componentDidMount() { if (this.props.student) { const { pk, name, address, role, department, salary } = this.props.student; this.setState({ pk, name, address, role, department, salary }); } } onChange = e => { this.setState({ [e.target.name]: e.target.value }); }; createStudent = e => { e.preventDefault(); axios.post(API_URL, this.state).then(() => { this.props.resetState(); this.props.toggle(); }); }; editStudent = e => { e.preventDefault(); axios.put(API_URL + this.state.pk, this.state).then(() => { this.props.resetState(); this.props.toggle(); }); }; defaultIfEmpty = value => { return value === "" ?

KeyError handling while consuming API
I am consuming the Yelp API and using this detail view to display details of individual restaurants such as the name, rating and price of a restaurant. The detail dictionary is solid for the most part and lets me collect variables to use as context in template. However some restaurants do not provide their 'price' to the API, therefore when accessing this view I get a KeyError because there is no price in some cases. How can I create this dictionary with a None value for price to avoid this error? Or is exception handling with try & except the best solution? def detail(request, api_id): API_KEY = 'unique_key' url = 'https://api.yelp.com/v3/businesses/'+ api_id headers = {'Authorization': 'Bearer {}'.format(API_KEY)} req = requests.get(url, headers=headers) parsed = json.loads(req.text) detail = { 'id': parsed['id'], 'name': parsed['name'], 'rating':parsed['rating'], 'price': parsed['price'], } context = {'detail': detail} return render(request, 'API/detail.html', context) -
Django - add link with custom admin page href
In my Django project, I have created a custom admin page for an app via the get_urls() method. I'd like to add a link to the app's main model index view that will take users to this custom page - however, I'm having some trouble creating this link element correctly and I don't seem to be able to piece together the right way to do it - I'm just left with a Reverse for 'export' not found. 'export' is not a valid view function or pattern name. error.

Docker Wordpress/Apache behind Docker Nginx - Port Number Issue
I am having problems getting the wordpress docker image working with the nginx docker image. The python/django container works perfectly fine with nginx, but the wordpress/apache one is having problems. I can get to the django site, with https. I cannot get into the wordpress one with https. In fact, when I go to my site site.com/wp, I get back site.com:8080/wp, so for some reason it is coming back through port 8080, and not 443 or 80. I've tried setting the wordpress site as the root location / (in the default.conf file) and it still has the same problem (then I get site.com:8080). The wordpress functionality is normal, I can edit the site as usual. default.conf file for nginx disable_symlinks off; ssl_certificate xxx ssl_certificate_key xxx server { listen 80; return 301 https://$host$request_uri; } server { listen 443 ssl; server_name site.com; location / { proxy_pass http://django:8000; #django container } location /static { alias /path/to/static; } location /wp { proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $remote_addr; proxy_set_header Host $host; proxy_pass http://wordpress:80; #the wordpress container } } docker yml version: '3.7' services: django: restart: always build: context: . dockerfile: docker-django #django gunicorn server, python image ports: - "8000:8000" wordpress: restart: always build: context: . … -

Django - How to turn a Page object to Json

django: Unable to get sorl-thumbnail working
I am making a django site where users can upload images and I want to use sorl-thumbnail for thumbnail generation and caching. I am using a container based workflow using podman on a fedora silverblue host. I have setup a memcached cache engine (using the memcached docker image), and can set and get values to and from the cache in django-shell with no issues. I have run the migrate command with sorl-thumbnail added to my installed-apps. I have run the ./manage.py createcachetable command and no errors. I am using pylibmc with: CACHES = { 'default': { 'BACKEND': 'django.core.cache.backends.memcached.PyLibMCCache', 'LOCATION': '127.0.0.1:11211', } } I have created a model which has the sorl.thumbnail ImageField, although I hope to use a standard imagefield eventually, which I believe is possible. I have checked my postgres database and the thumbnail_kvstore table is created but never populated with any data. I have the following model, view, and template: model... class Image(models.Model): image_file = ImageField(upload_to=user_directory_path) #thumbnail = models.ImageField(upload_to=str(user_directory_path) + '_thumb', null=True) userprofile = models.ForeignKey(ForumProfile, on_delete=models.CASCADE, related_name="images") view...(the get function is added during debugging this issue)... class ForumProfileUploadView(LoginRequiredMixin, FormView): form_class = ImageForm template_name = 'list.html' success_url = reverse_lazy('my-view') def get(self, request, *args, **kwargs): form = self.form_class() message = … -

Does Django Channels support a synchronous long-polling consumer?
I'm using Channels v2. I want to integrate long-polling into my project. The only consumer I see in the documentation for http long polling is the AsyncHttpConsumer. The code I need to run in my handle function is not asynchronous. It connects to another device on the network using a library that is not asynchronous. From what I understand, this will cause the event loop to block, which is bad. Can I run my handler synchronously, in a thread somehow? There's a SyncConsumer, but that seems to have something to do with Web Sockets. It doesn't seem applicable to Long Polling. -

python Django fill in auto-created Profile model with User registration form
I am creating an art marketplace with django. I have the registration and the auto-create signal set up for the profile. There are three types of Users who will register on this app: Artists, Patrons, and Brokers (I call these user_status.) I would like the User to choose one of these three fields on the registration form. I have gotten to the point where the reg form has the choicefield and the choices and the user can select one and the form saves to create the User and Profile, but the profile does not have a selected 'user_status' when I go in to admin. I am aware it is heavily discouraged to bundle up profile modelfields at registration, but I'd like for just this one field to be selectable since it will have a major effect on how the site will look for the user. I have read (here) that there would be a lot of annoying customization involved to properly fill profile fields at registration. Is this true? I think if there is a solution it'll be on Signals.py but am not sure. In signals.py when I type in: user_status='Patron', Can I replace the 'Patron' with something like instance.get('user_status')? … -

Hi I'm trying to get some data from an model with a while loop. So in the code shown below n is a number and orderMessage is the data I want to append to an list. So what the loop should do is get as many rows as the number n and append it to a list Full. orderMessage changes depending on the index i given to the filter statement. Now my question is, for ex. n = 12 so I want to get the last 12 entries from the MessageItem Model and append it to a list. How could I do that? n = CartQuantity.objects.filter(customer=customer).values_list('cquantity', flat=True).last() m = MessageItem.objects.filter(customer=customer).last() i = 0 while i <= n: orderMessage = MessageItem.objects.filter(customer=customer)[i] Full = [] aFull = Full.append(orderMessage) print(Full) send = aFull print(send) i += 1 message_to_send = str(message) + str(n) + str(m) Here are the models: class MessageItem(models.Model): customer = models.ForeignKey(Customer, on_delete=models.SET_NULL, blank=True, null=True) mItem = models.CharField(max_length=255, null=True) mQuantity = models.CharField(max_length=255, null=True) mOrderItem = models.CharField(max_length=255, null=True) class CartQuantity(models.Model): customer = models.ForeignKey(Customer, on_delete=models.SET_NULL, blank=True, null=True) cquantity = models.IntegerField(default=0, null=True, blank=True) I hope you guys understand my english and my question. I'm very thankful for any solutions
