Need to add a search functionality on Django class based view
I have a search function on a function based view that works fine. This is the function based view code: def BlogList(request): blogs = Blog.objects.all() if request.method == 'GET': search = request.GET.get('search', '') blogs = Blog.objects.filter(blog_title__icontains=search) return render(request, 'App_Blog/blog_list.html', context={'search':search, 'blogs':blogs}) But now I want to replace that function based view by implementing it on this class based view. class BlogList(ListView): context_object_name = 'blogs' model = Blog template_name = 'App_Blog/blog_list.html' This is my models.py: class Blog(models.Model): author = models.ForeignKey(User, on_delete=models.CASCADE, related_name='post_author') blog_title = models.CharField(max_length=264, verbose_name="Put a Title") slug = models.SlugField(max_length=264, unique=True) blog_content = models.TextField(verbose_name="What is on your mind?") blog_image = models.ImageField(upload_to='blog_images', verbose_name="Image") publish_date = models.DateTimeField(auto_now_add=True) update_date = models.DateTimeField(auto_now=True) class Meta: ordering = ['-publish_date',] def __str__(self): return self.blog_title html part for search function: <form class="form-inline ml-auto" method="GET"> <input class="form-control mr-sm-2" type="text" name="search" placeholder="Search the topic"> <button class="btn btn-success" type="submit">Search</button> </form> As I am a newbie, I have tried different solutions but not getting it through.

Python Billiard cannot find project module on restarting Celery worker process

A Difficult Object Query
So, I have an e-commerce website that I am building. When the customer clicks "place order", the site creates the order, and the database updates totally fine. The problem lies in displaying the order summary. IF the customer has ordered from the company in the past, that order is stored in the database along with the new one. The site then throws the error "2 objects returned" when I try to access it through the foreign key that relates the order table to the User table. The reason for this is obvious to me so I added a datetime field and set the auto_now_add attribute to TRUE. The problem I'm having is selecting the latest order for that particular customer. Is there a way to use something like this? user = request.user Order.objects.filter(Customer=user).date_placed.latest() The fact that filter() returns a set makes me think that sytax won't execute properly. Maybe with a for loop inside a function that takes User as a parameter? I have no idea how to approach this one and thought I'd reach out. Thanks you guys. View for the request: def orderSummary(request): context = {} if request.user.is_authenticated: owner = request.user.id user = request.user cart = Cart.objects.get(cart_owner=owner) held_items … -
Struggling to display images using django

Vue.js and drf images

Is it better to create a OneToOne relation or a custom filed? [DJANGO]
I want to create a Venue model and save the location object, here's my code that actually works: class Location(models.Model): latitude = models.FloatField() longitude = models.FloatField() address = models.CharField(max_length=100, blank=True) city = models.CharField(max_length=100, blank=True) class Venue(models.Model): name = models.CharField(max_length=255) location = models.OneToOneField(Location) As you can see, if I delete Venue the corresponding location will not be deleted, because OneToOne works so. Is it better to create a custom field, let's say LocationField, with latitude, longitude... properties and put it inside Venue, or is this the right solution? -
Django - Saving multiple optional objects with a CreateView
I'm working on a real estate app where users can apply to rent a house or apartment. I'm having trouble grasping the concept of saving multiple objects and tying them together. I want the form to allow 1 to 4 people to apply for a single property. I either want 1 page where the user can select the number of applicants and the form save X number of people objects or I'm thinking of adding 2 buttons, on one to save and complete (current person), and another to save and add a new person. Additionally, I want to add all the applicants to a single application table. so I can query my database to view all the applicants on a single application. I'm not sure the best way to handle that. models class Properties(models.Model): property_num = models.IntegerField() property_road = models.CharField(max_length=200) rent = models.IntegerField(default=1000) city = models.CharField(max_length=200) state = models.CharField(choices=STATE_CHOICE, max_length=25) zip = models.IntegerField() bedrooms = models.IntegerField() bathrooms = models.FloatField(max_length=3) sq_foot = models.IntegerField() description = models.TextField(default=bedrooms) is_active = models.BooleanField(default=True) thumbnail = models.ImageField(upload_to='static/images', blank=True) slug = models.SlugField(blank=True, null=True, unique=True, allow_unicode=True) class Person(models.Model): address = models.ForeignKey(Properties, on_delete=models.CASCADE) requested_move_in_date = models.DateField(default=datetime.now) first_name = models.CharField(max_length=200) middle_name = models.CharField(max_length=200) last_name = models.CharField(max_length=200) dob = models.CharField(max_length=200) driver_license … -

How to redirect a wrong url with the same pattern that a user messed up in django, without javascript
assume the following: Your model has: Products.slug urls: path('<int:id>/<slug:slug>/', views.product_detail, name='product_detail'), views: products = Products.objects.get(id=id, slug=slug) Someone goes to /products/1/brazil-nuts/, and it goes to the right page. But then someone copy/pastes the url wrong to: /products/1/brazil-nu/ Then you get a DoesNotExist error... Now you could "fix" this by not forcing the slug=slug argument in your query, but then the url is incorrect, and people could link from /products/1/brazil-nu-sjfhkjfg-dfh, which is sloppy. So how would I redirect an incorrect url to the correct one with the same url structure as the correct one (only id and slug arguments), without relying on JavaScript's window.history.pushState(null, null, proper_url); every time the page loads? I've already tried making the same url pattern to redirect, but since django uses the first pattern match, it won't work no matter where you put the url in your list. -

Python/Django sorting a queryset by distance in REST framework
Currently, I am adding a field, 'distance', to a queryset after it's been created, and then returning it. However, I would like to sort the queryset by distance, if it's possible to annotate it. Currently, my model, GeoCache, has fields latitude and longitude as models.DecimalField(max_digits=15, decimal_places=10, null=True, blank=True). Using geopy, I can add distance to my queryset like this: user_location = (self.request.GET.get('latitude') , self.request.GET.get('longitude')) geocache_list = GeoCache.objects.all() for geocache in geocache_list: geocache.distance = geodesic(user_location, (geocache.latitude, geocache.longitude)).miles return geocache_list However, I would like to sort the queryset by distance, from lowest to greatest. However, when I try to annotate the search as such: geocache_list = GeoCache.objects.all().annotate(distance=geodesic(user_location, ('latitude', 'longitude')).miles) I get the error, "ValueError: could not convert string to float: 'latitude'" Is there a better way to annotate this so that I can sort by distance within the queryset? -
How to update the data of a POST view that I have already updated with the same AJAX function?
We used AJAX to launch a POST request with a set of data. We noticed that a piece of data was being sent incorrectly. After fixing it, we sent the request again but the web where we display the data is not updated, despite having checked that the request sends the data correctly. Could someone tell me how can I fix it please?

Here they are: models.py class Question(models.Model): question_title = models.CharField(max_length = 100) question_description = models.TextField() question_tags = models.TextField() def __str__(self): return self.question_title class Solution(models.Model): user_profile = models.ForeignKey(UserProfile, on_delete = models.SET_NULL) question_id = models.ForeignKey(Question, on_delete = models.CASCADE, blank = False, null = True) solution = models.TextField() date_modified = models.DateTimeField(auto_now_add = True) def __str__(self): return "[SOL] " + self.question_id + "/" + self.user_profile Here's my views.py: class QuestionList(generics.GenericAPIView, mixins.ListModelMixin, mixins.CreateModelMixin): # Used to access all questions and adding one queryset = Question.objects.all() serializer_class = QuestionSerializer def get(self, request): return self.list(request) def post(self, request): return self.create(request) class QuestionDetails(generics.GenericAPIView, mixins.RetrieveModelMixin, mixins.UpdateModelMixin, mixins.DestroyModelMixin): queryset = Question.objects.all() serializer_class = QuestionSerializer lookup_field = 'id' def get_question(self, id): try: return Question.objects.get(id = id) except Question.DoesNotExist: raise Http404 def get(self, request, id): question = self.get_question(id) serializer = QuestionSerializer(question) return Response(serializer.data, status.HTTP_200_OK) def put(self, request, id): question = self.get_question(id) serializer = QuestionSerializer(question, data = request.data) if serializer.is_valid(): serializer.save() return Response(serializer.data, status = status.HTTP_201_CREATED) return Response(serializer.errors, status = status.HTTP_400_BAD_REQUEST) def delete(self, request, id): question = self.get_object(id) question.delete() return Response(status = status.HTTP_204_NO_CONTENT) class SolutionList(generics.GenericAPIView, mixins.ListModelMixin,mixins.CreateModelMixin): # Empty because I'm still incredibly confused … -
Django - How Do I Set A Default Value In A Form To Be The Current User?
quick beginner Django question because I haven't been able to find an answer that directly solves what i'm after, or doesn't add in a bunch of overcomplicated functionality I don't need with its answer. I have a basic Blog setup, with a model for users and their associated posts, and a form for creating new posts. However all I want is for the "Author" field on the form to be automatically populated with the currently logged in user, rather than being a drop down list of all the registered users. My Model: class Post(models.Model): title = models.CharField(max_length=255) author = models.ForeignKey(User, on_delete=models.CASCADE) body = models.TextField() post_date = models.DateField(auto_now_add=True) category = models.CharField(max_length=255) site = models.CharField(max_length=255) def __str__(self): return self.title + ' | ' + str(self.author) def get_absolute_url(self): return reverse('home') My Form: class PostForm(forms.ModelForm): class Meta: model=Post fields = ('title', 'author', 'category', 'site', 'body') widgets = { 'title': forms.TextInput(attrs={'class': 'form-control'}), 'author': forms.Select(attrs={'class': 'form-control' ,'readonly': 'readonly'}), 'category': forms.Select(choices=choice_list,attrs={'class': 'form-control'}), 'site': forms.Select(choices=site_choice_list,attrs={'class': 'form-control'}), 'body': forms.Textarea(attrs={'class': 'form-control'}) } To reiterate, I simply want the 'author' field in the post to be read-only and populated with the current logged in user. Rather than the user being able to select from a list of users. Thank you in … -

Django sending emails and response to Vue/Axios
I am struggling to send emails from Vue3/Axios frontend through Django. in Vue3 I send my form fields using axios: <script lang="ts"> import axios from 'axios'; axios.defaults.xsrfCookieName = 'csrftoken'; axios.defaults.xsrfHeaderName = 'X-CSRFToken'; export default { name: "Contact", data() { return { name: '', email: '', phone: '', message: '' }; }, methods: { sendEmail() { axios .post("send_email/", { name: this.name, email: this.email, phone: this.phone, message: this.message, xstfCookieName: 'csrftoken', xsrfHeaderName: 'X-CSRFToken', headers: { 'X-CSRFToken': 'csrftoken', } }) .then((response) => { console.log(response); }) } } }; </script> I can see my fields in the request header without any problems. I could not manage to write a correct view sending email and response the request. def contactView(request): if (request.POST): try: form = ContactForm(request.POST) if form.is_valid(): subject = form.cleaned_data['subject'] name = form.cleaned_data['name'] from_email = form.cleaned_data['email'] message = form.cleaned_data['message'] print(subject) try: send_mail(subject, message, from_email, ['admin@example.com']) return HttpResponse(json.dumps({'response': 'Ok'}), content_type = "application/json") except BadHeaderError: return HttpResponse(json.dumps({'response': 'Ko', 'message': 'invalid header found'}), content_type = "application/json") except: return HttpResponse(json.dumps({'response': 'Ko', 'message': 'Cannot be sent'}), content_type = "application/json") else: return HttpResponse(json.dumps({'response': 'Ko', 'message': 'Cannot be sent'}), content_type = "application/json") Can you help me to fix this ? Thanks
