JQuery ломает CSS стили
всем привет, сразу извиняюсь за возможно довольно глупый вопрос который скорее всего напрямую связан с моими кривыми руками, но, тем не менее есть проблема с тем что при подключении файлов JQuery в мой Django проект ломаются все стили на странице к которой подключаю, до подключения всё работает корректно. Я новичок и скорее всего просто чего-то не понимаю, и не могу уже какой день решить эту проблему, сразу скажу что я знаю про collect static и все те вещи которые нужно делать со статическими файлами, ибо стили работают нормально и в файле settings.py все пути указаны верно. код скрипта довольно простой и служит по большей части чисто для адаптивного меню, и скрытия некоторых тегов html по нажатию. JQuery код скрипта довольно простой и служит по большей части чисто для адаптивного меню, и скрытия некоторых тегов html по нажатию. $(document).ready(function() { // Менюшка и появляющиеся категории $('.nav_show_btn').click(function() { let display = $('.nav_show_links').css('display') if (display == 'none') { $('.nav_show_links').slideDown('100') } else { $('.nav_show_links').slideUp('100') } }) $('.category_btn').click(function() { let display = $('.categorys_container').css('display') if (display == 'none') { $('.categorys_container').slideDown('100') $('.category_btn').addClass('active') } else { $('.categorys_container').slideUp('100') $('.category_btn').removeClass('active') } }) // Профиль и его меню { let active; $('#main_inf_user').click(function() { if (active != 'off' | active == undefined) … -
Django model design for Shopping List. how to use ManytoMany relationship?
I am working on making django app to handle multiple shopping list. which should have ManytoMany field? Item model or List model? is this model optimal ? A list can have many items, many sublists, many associated store. And, except for List vs Sublist all the relationships are many to many. An item can be in many list, a store can be associated to many list. sublist is just putting the item in categories so I can also remove this model and add a category attribute to items. Item has m2m fields for List but should it also have m2m field for Sublist? a List need not have sublist so the item can be part of list or sublist in a list (like a folder/file structure) models.py: class List(models.Model): name = models.Charfield(max_length=125) date = models.DateField(default=django.utils.timezone.now) class Store(models.Model) : name = models.CharField(max_length=128) store = models.ManyToManyField(List) class Item(models.Model): item = models.CharField(max_length=128) price = models.FloatField(default=0.0) category = models.CharField(max_length=128, default=None) checked = models.BooleanField(default=None) store = models.ManyToManyField(List) class SubList(models.Model): name = models.Charfield(max_length=256) parent_list = models.ForeignKey(List) items = models.ManyToManyField(Item) -
UpdateView Doesn't Save Data, returns object field data in url
After a LOT, LOT, LOT of research, I COULD NOT FIND OUT why UpdateView in django wasn't saving form data upon being saved. Instead, it saved the data in a url when it redirected me back to an un-edited object detail view. I'm sharing the same template for CreateView and UpdateView Here's my Views.py from django.shortcuts import render, redirect, get_object_or_404 from django.urls import reverse from django.views import View from .models import Blog from .forms import BlogForm from django.views.generic import ( CreateView, ListView, DetailView, UpdateView, DeleteView ) class BlogListView(ListView): template_name = 'blogtemplates/blogs.html' queryset = Blog.objects.all() model = Blog paginate_by = 4 def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) # Add in a QuerySet of all the books context['object_list'] = Blog.objects.all() return context class BlogDetailView(DetailView): model = Blog template_name = 'blogview.html' queryset = Blog.objects.all() def get_object(self): id_ = self.kwargs.get("pk") return get_object_or_404(Blog, id=id_) def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) # Add in a QuerySet of all the books context['object_list'] = Blog.objects.all() return context class BlogCreateView(CreateView): template_name = 'blogpost.html' form_class = BlogForm queryset = Blog.objects.all() def get_context_data(self, **kwargs): # Call the base implementation first to get a context context = super().get_context_data(**kwargs) # Add in a QuerySet of all the books context['object_list'] = Blog.objects.all() return context … -
matching query does not exist - how can I get an item from an API and save it to a user's profile?
I'm trying to add an item of a search result into a user's profile. The thing is, when I look for the items, they are not saved into my database unless the user saves them to their profile (that's my intention). My code is supposed to get the item by its id (which in my code was supposed to be the id it has on the API but that doesn't seem to work) but since the item is in the API and not in my database, it doesn't work. So how can I manage to get the item from the API and save it to the user's profile (and, that way, to my database)? These are the models: class Anime(models.Model): title = models.CharField('Title', max_length=150) episodes = models.IntegerField() image = models.ImageField() mal_id = models.IntegerField(null=True) def __str__(self): return self.title class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) favorites = models.ManyToManyField(Anime, related_name='favorited_by', null=True, blank=True) @receiver(post_save, sender=User) def create_user_profile(sender, instance, created, **kwargs): if created: Profile.objects.create(user=instance) @receiver(post_save, sender=User) def save_user_profile(sender, instance, **kwargs): instance.profile.save() These are the views: def search(request): animes = [] if request.method=='POST' and 'search' in request.POST : animes_url = 'https://api.jikan.moe/v3/search/anime?q={}&limit=6&page=1' search_params = { 'animes' : 'title', 'q' : request.POST['search'] } r = requests.get(animes_url, params=search_params) results … -
OpenCV can't capture frames on production server (Nginx + uWSGI)
I'm building a production server on Raspberry Pi 4. Web app is written in Django. I used uWSGI as an application server and Nginx as a reverse proxy. I followed many tips from Digital Ocean. One of the tasks is to stream frames from USB camera connected to RPi. My inspirations was post from PyImageSearch, but I wanted to do it in Django. Code looks as follows: # views.py from django.views.decorators import gzip from django.http import StreamingHttpResponse import cv2 import threading class VideoCamera(object): def __init__(self): self.video = cv2.VideoCapture(0) (self.grabbed, self.frame) = self.video.read() if not self.grabbed: print("Can't open camera") threading.Thread(target=self.update, args=()).start() def __del__(self): self.video.release() def get_frame(self): image = self.frame _, jpeg = cv2.imencode('.jpg', image) return jpeg.tobytes() def update(self): while True: (self.grabbed, self.frame) = self.video.read() def gen(camera): while True: frame = camera.get_frame() yield(b'--frame\r\n' b'Content-Type: image/jpeg\r\n\r\n' + frame + b'\r\n\r\n') @gzip.gzip_page def camera_usb(request): try: cam = VideoCamera() return StreamingHttpResponse(gen(cam), content_type="multipart/x-mixed-replace;boundary=frame") except: print("Something went wrong") and then I use code of 'camera_usb' view in urls.py and in template. It works fine both on my laptop and on RPi 4, but only on development server. After running on production server I get following message from sudo systemctl status uwsgi: uwsgi.service - uWSGI Emperor service Loaded: … -

Issue for user from an existing database to login in a Django website
There is my problem, so I need to create a Django app and I think I have to use an already existing database with users in. So I did some research and figured out some issues. So Django store the password with the salt and use it to check the password.But no one says that there will be salt + hashed type password in the database, but we can get read of this issue with the proper check function (related to the encryption function) I think, like this guy Django check_password() always returning False who used bcrypt.checkpw(password, hashedPassword) because in his database passwords are encrypted with bcrypt. The solution proposed was to create a custom authentification backend (even if I don't really see how we can do this I may be able to find out a tuto to do so) but the main issue is that how I can save a user password who register through the Django web site with the same type of hash that the one already existing in the database (with no salt). I'm a really sorry for not be able to give you more precision about how the password are stored in the database because … -

Django model class with multiple objects from other model class
I want to create a Django model schema to track yacht racing results. This is a highly simplified version, but want to only focus on the relationships and schema first; class Yacht(models.Model): name = models.CharField(max_length=50) class Event(models.Model): event_number = models.IntegerField() class Result(models.Model): yacht = models.ForeignKey(Yacht, on_delete = models.CASCADE) event_number = models.ForeignKey(Event, on_delete = models.CASCADE) result = models.IntegerField(default=0) Question: How would you approach this problem where I want to create an Event, and have it list all the yachts where I can enter their time? I'd like to be able to do this in the Admin 'all at once' instead of going to each yacht. Eventually, I want this to display as a form for a user. For example, if a user clicks on a race event, it loads a page with all the yachts and their time slot. Julien -

Logger in my view file: LOGGING = { 'version': 1, 'disable_existing_loggers': False, 'handlers': { 'views_error_file': { 'class': 'logging.FileHandler', 'filename': 'logs/errors/views.debug.log', }, 'views_info_file': { 'class': 'logging.FileHandler', 'filename': 'logs/infos/views.debug.log', }, 'views_debug_file': { 'class': 'logging.FileHandler', 'filename': 'logs/debugs/views.debug.log', } }, 'loggers': { 'py_folder.views': { 'handlers': ['views_error_file'], 'level': 'ERROR', }, 'py_folder.views': { 'handlers': ['views_info_file'], 'level': 'INFO', }, 'py_folder.views': { 'handlers': ['views_debug_file'], 'level': 'DEBUG', } } } The views.py file: import logging # Get an instance of a logger logger = logging.getLogger(__name__) def sample_function(request): params_choices = ['param_1', 'param_2'] sample_param = request.POST.get('sample_param') # logger.debug should be logged at logs/debugs/views.debug.log logger.debug(sample_param) if sample_param in params_choices: if sample_param == 'param_1': # logger.info should be logged at logs/infos/views.debug.log logger.info("param_1 okay") return redirect("/param_1-req") else: # logger.error should be logged at logs/error/views.debug.log logger.error("param_2 okay") return redirect("/param_2-req") else: logger.error("param does not exist") return redirect("/param-invalid") But its only going in to the logs/debugs/views.debug.log. The logs/debugs/views.debug.log file: param_3 param does not exist I tried changing the logs/infos/views.debug.log to logs/infos/views.info.log and logs/error/views.error.log to logs/error/views.error.log but nothing changed. I don't know why … -
