scroll down button changes url django
I am working on a django website which contains a button at the top of the page, which when clicked should scroll down. The button is enclosed in an anchor tag, with a specified href attribute. When I click the button the program alters the url, resulting in a 404 error. How do I code this to ensure that the url is not affected when the button is clicked? This is my code so far <a class="scroll_down_button" href='.second_part'>click</a> <div class="second_part"> This is a test </div> This is the error I am getting Page not found (404) Request Method: GET Request URL: http://127.0.0.1:8000/.second_part -
Hotel Reservation system in Django: How to make a room unavailable to other users for a period of time
I am building a hotel reservation system for my a-level coursework and my problem is when a user books a room I want to make sure no other user can reserve that room for the duration of the time period that the room is occupied. I tried using iteration to loop over the dates and have a boolean value that is set to true when the room is reserved and false when it is not. Here is my models class Room(models.Model): name = models.CharField(max_length = 200) img = models.ImageField(upload_to='Pictures') desc = models.TextField() price = models.IntegerField() is_reserved = models.BooleanField(default=False) number_of_people = models.PositiveIntegerField() def __str__(self): return self.name class Meta: verbose_name = 'Room' verbose_name_plural = 'Rooms' class Reservation(models.Model): check_in = models.DateField(default=timezone.now) check_out = models.DateField() room = models.ForeignKey(Room, on_delete = models.CASCADE) guest = models.ForeignKey(User, on_delete= models.CASCADE) class Meta: verbose_name = 'Reservation' verbose_name_plural = 'Reservations' This is my function in views where it will loop over the checkin and check out dates inputted by the user and make sure that no other user can reserve that room for those dates def confirm(request, pk = None): if request.method == 'POST': if pk: room_id = Room.objects.get(pk = pk) guest_id = request.user check_in = request.session['check_in'] check_out = request.session['check_out'] … -
What does 'group_list' object has no attribute 'object' mean?
I want to create listview and createview on the same screen, but I do not understand the meaning of the current error "'group_list' object has no attribute 'object'". I tried to create it on the basis of createview, but the list was confused. I also tried to create and inherit the createview and listview classes, but the same error occurred. #error 'group_list' object has no attribute 'object' #forms class GroupRequestForm(mixins.BaseModelForm): class Meta: model = belong fields = ('group',) #view class group_list(ListView,ModelFormMixin): model = group form_class = GroupRequestForm template_name = 'group/group_list.html' context_object_name = 'group_list' queryset = group.objects.all() def form_valid(self, form): group_pk = self.kwargs['pk'] comment = form.save(commit=False) comment.post = get_object_or_404(group, pk=group_pk) comment.save() return redirect('app:detail_and_create', pk=group_pk) def post(self, request, *args, **kwargs): self.object = self.get_object() # assign the object to the view form = self.get_form() if form.is_valid(): return self.form_valid(form) else: self.object = self.get_object() return self.form_invalid(form) # class group_list(CreateView,): # form_class = GroupRequestForm # template_name = 'group/group_list.html' # success_url = reverse_lazy('group:group_list') # # def get_context_data(self, *, object_list=None, **kwargs): # context_data = super(group_list, self).get_context_data(**kwargs) # context_data['group_list'] = group.objects.all() # return context_data # # def form_valid(self,form): # user = self.request.user # # POST.get('user_id') # form.instance.user = user # return super().form_valid(form) # class group_list(ListView): # model = group … -

How to fix form fields not appearing in html/django?
I'm very new to Django and was following a tutorial on creating a user registration page. However, when I run the server the form fields don't appear and only the submit button is there. I looked through many tutorials and tried to change the UserForm class thinking that that was the problem but I get the same issue. forms.py from django import forms from django.contrib.auth.forms import UserCreationForm from django.contrib.auth.models import User class UserForm(forms.ModelForm): password = forms.CharField(widget=forms.PasswordInput) class Meta: model = User fields = ["username", "email", "password"] views.py ... class UserFormView(View): form_class = UserForm template_name = 'static/register.html' def get(self, request): form = self.form_class(None) return render(request, self.template_name, {"form":form}) def post(self, request): form = self.form_class(request.POST) if form.is_valid(): #creates an object frm the form but doesnt save it into the database user = form.save(commit=False) username = form.cleaned_data['username'] password = form.cleaned_data['password'] user.set_password(password) user.save() #returns object if credenials are correct user = authenticate(username=username, password=password) if user is not None: if user.is_active: login(request, user) return redirect('main:homepage') return render(request, self.template_name, {"form":form}) urls.py from django.urls import path from . import views from django.conf.urls import url, include app_name = "main" urlpatterns = [ path("", views.homepage, name="homepage"), path("register/", views.UserFormView.as_view(), name='register'), ] register.html {% extends 'static/header.html' %} {% block content %} <br> … -

Django not saving form data
I've made a simple test django project that's a simple list of posts. And I'm trying to add functionality to update a post. Everything seems to be working, except the edits aren't saved to the database. I've checked the cleaned data to see if the updated data is coming through, and it is, but the save() function doesn't seem to actually do anything. models.py class Block(models.Model): title = models.CharField(max_length=255) slug = models.SlugField(unique=True, max_length=140, null=True, blank=True) content = models.TextField() def save(self, *args, **kwargs): if self.slug is None: self.slug = get_unique_slug(self, 'title', 'slug') super().save(*args, **kwargs) def get_absolute_url(self): return reverse("bulkapp:one_view", kwargs={"slug_id": self.slug}) def __str__(self): return self.title views.py def edit_block_view(request, slug_id): single_block_query = get_object_or_404(Block, slug=slug_id) update_form_query = BlockForm(request.POST or None, instance=single_block_query) if update_form_query.is_valid(): update_form_query.save() return redirect('bulkapp:one_view', slug_id=slug_id) return render(request, 'bulkapp/update.html', {'update_form': update_form_query}) <form class="form-container" method="POST"> {% csrf_token %} {{update_form.as_p}} <input type="submit" value="Edit"> </form> The redirect fires as expected, but no changes are saved, and no error messages are written to the console.

How to save Django QuerySet directly into redis?
I'd like to save results of Django QuerySets directly into redis instead of using built in cache.set and cache.get. The reason is that I'd like to use a separate redis db for certain queries to accelerate data retrieval. Here is my sample code: def cached_post(id): r = redis.StrictRedis(unix_socket_path='/var/run/redis/redis.sock', db=6) key = "tpcpots:" + id if not r.get(key): post = Post.objects.get(pk = id) r.set(key, post, AN_HOUR) return r.get(key) But I get this error: cannot concatenate 'str' and 'long' objects How can I fix this? -
How to set custom rates, for throttling in django rest framework?

What is the standard or the best way to filters using boolean field and retrieve the resources accordingly?
I have a use case where I want to list the resources(posts) based on the filters applied which are all, active and inactive. There is a flag in the Django post model which has is_active status. I want to know what is the best way to design the API contract for this filter. The list post API is a POST API call. Context below: Filters in UI (Multiple Checkbox): All Active Inactive If all is selected, then select both Active and Inactive. Ideal Output: If all is select, then show the list the posts irrespective of the statuses. If None are selected, then show the list the posts irrespective of the statuses. If either Active or Inactive is selected, then list the posts with respect to that. class Post(models.Model): author = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) title = models.CharField(max_length=200) text = models.TextField() created_date = models.DateTimeField(default=timezone.now) published_date = models.DateTimeField(blank=True, null=True) is_active = models.BooleanField(default=True) def publish(self): self.published_date = timezone.now() self.save() def __str__(self): return self.title The approach is to have a flag as status in post API and values can be true, false, null. { ... "status": true, ... } Approaches are: if the status is true, then list only post with true status. if the … -

How to update data in database table using conditional expression
I want to update my data in my database table only if conditional expression work. I have a dictionary called result_total which is continuously updated. Using for loop condition I want to update my data. For example: if result_total[news_item][2] is equal to any of my database table entries then result_total[news_item][2] will not be updated for news_item in result_total: if Haberler.objects.get(haber_link=result_total[news_item][2]): Haberler.objects.filter(sira_no=news_item).update( haber_id=result_total[news_item][0], haber_baslik=result_total[news_item][1], haber_link=result_total[news_item][2], haber_imagelink=result_total[news_item][3], haber_text=result_total[news_item][4] ) error messages shows following "Haberler matching query does not exist." -
Is it possible to query a database based on it's __str__?
Let's say theoretically I have these 3 models: class Cable(models.Model): id = models.OneToOneField(Item, primary_key=True, on_delete=models.CASCADE) type = models.IntegerField(choices=choices.cableTypes, default=1) notes = models.TextField(blank=True) length = models.DecimalField(decimal_places=2, max_digits=6) def __str__(self): return str(self.get_type_display()) + " Cable, " + str(self.length) + "m" class Adapter(models.Model): id = models.OneToOneField(Item, primary_key=True, on_delete=models.CASCADE) adaptFrom = models.IntegerField(choices=choices.connectors, default=1) adaptTo = models.IntegerField(choices=choices.connectors, default=1) notes = models.TextField(blank=True) length = models.DecimalField(decimal_places=2, max_digits=6) def __str__(self): return str(self.get_adaptFrom_display()) + " to " + str(self.get_adaptTo_display()) class Fixture(models.Model): id = models.OneToOneField(Item, primary_key=True, on_delete=models.CASCADE) type = models.IntegerField(choices=choices.fixtureTypes, default=1) model = models.CharField(blank=False, max_length=128) manufacturer = models.CharField(blank=False, max_length=128) notes = models.TextField(blank=True) def __str__(self): return str(self.manufacturer) + " " + str(self.model) Is it possible to query these models based on the string they return? If not, how would I go about doing something similair to it? The reason I need to do this is because I have a parent model called item (which is where all of these models get their primary keys from) but I still need to implement a search function to my website. Here is my current way of doing it, which is a bit messy: results = [] form = SearchForm(request.POST) if form.is_valid(): for category in Type.objects.all(): for item in Item.objects.all(): if item.type == category: model … -

How to refresh part of a Django page with AJAX?
I am deploying a website using Django. There is an application called 'forum', supporting a discussion forum on my website. The url of the discussion forum is 'XXX.com/forum/roomY'. I want to refresh a div id = ''chat'', which includes a message list, on this page when users click a refresh button. I want to use AJAX to do that. But I find that I could not call the function updatestatementlist(request) to retrieve the updated message list so it can be passed to the on this page. /forum/views.py def updatestatementlist(request): log.debug("call statementlist function") statements = Statement.objects.filter(discussion=discussion) return render(request, 'forum/statementlist.html', { 'statements': statements }) I cannot see the log info so I think by clicking the button I fail to call this function. The main html page of the discussion forum is /forum/discussion.html, which is under the template folder. I extract the html code within the div id = "chat" to a separate html /forum/statementlist.html as suggested here and several other SO posts. /forum/discussion.html <button id = "Refresh"> Refresh </button> <div id="chat"> {% include 'forum/statementlist.html' %} </div> /forum/statementlist.html {% recursetree statements %} {% endrecursetree %} forum.js //When users click the refresh button $("#Refresh").on("click", function(event){ alert("Refresh clicked") $.ajax({ url: '', type: "GET", success: … -

Credentials aren't allowed error when using Outlook REST API Oauth2 in AWS server
I'm trying to implement Outlook Oauth2 in our Django backend server which is hosted on an AWS instance. I carefully followed the instructions in their python tutorial and it works 100% in my local machine. I am able to grab the authorization code which I then convert in my backend server to an access token. The problem lies in our demo server which is an AWS instance. We have a button that redirects the users to Outlook authentication. The URL has the following format: https://login.microsoftonline.com/common/oauth2/v2.0/authorize?client_id=<client-ID-here>&redirect_uri=<demo-server-redirect-url>&response_type=code&scope=openid+profile+offline_access+Calendars.ReadWrite&prompt=consent I am receiving the following error whenever I convert the authorization code into an access token just after the consent screen: { 'error': 'access_denied', 'error_description': 'Your credentials aren't allowed' } The weird thing is that if I use POSTMAN using the demo server Outlook credentials, I am able to retrieve an access token from Outlook. Basically, it works for both in my local machine and using Postman. I really think that I'm just missing a very small piece of code/configuration here. Are there some extra settings that I need to do in order to make Outlook Oauth2 work in AWS? -

Sorry for my bad English. I want to get binary image from request which contains image file from ajax. Because when user upload image file, I want to do OCR to the image file using google VISION API. Currently I'm using django, ajax. So when user upload the image, using ajax the file is passed to django view. I tried to get binary file in the views.py. But When I use request.FILES.get('file').read(), there is no data. But request.FILES.get('file').name is 'bank.png'... I think it's weird. Here is some code views.py def receipt_ocr(request): if request.method == 'POST': print(type(request.FILES["file"])) #<class 'django.core.files.uploadedfile.InMemoryUploadedFile'> print(type(request.FILES.get('file'))) #<class 'django.core.files.uploadedfile.InMemoryUploadedFile'> print(request.FILES.get('file')) #bank.png imageFile = request.FILES.get('file') print(imageFile.size) #119227 print(request.FILES.get('file').name) #bank.png print(request.FILES.get('file').content_type) #image/png print(type(request.FILES.get('file').open())) #<class 'NoneType'> print(request.FILES.get('file').open()) #None print(type(request.FILES["file"].read())) #<class 'bytes'> for chunk in imageFile.chunks(): print(chunk) #this generates lot of binary and some rdf:Description rdf:about= ... things receipt_image = imageFile.read() print(type(receipt_image)) print(receipt_image) ajax part // receipt OCR process $.ajax({ url: "{% url 'place:receipt_ocr' %}", enctype: 'multipart/form-data', type: 'POST', processData: false, contentType: false, data: postData, complete: function(req){ alert('good'); }, error: function(req, err){ alert('message:' + err); } }); What I exactly want to do is using this kind of code (google VISION API example code, OCR) def detect_text(path): """Detects text in the file.""" … -
models with ManyToManyField
suppose that you want to simulate universities system, you have courses, teachers, students. we have some courses that present by some teachers and student choose some courses with some teachers. for example: courses: math, physics teachers: Jack(math), Jane(math, physics) students: st1(math with Jack), st2(math with Jane), st3(physics with Jane and cant choose Jack!!), every score by default=-1. with this code: teachers = models.ManyToManyField(teacher.objects.filter(t_courses=s_courses), verbose_name='Ostad') I got errors like: raise AppRegistryNotReady("Models aren't loaded yet.") django.core.exceptions.AppRegistryNotReady: Models aren't loaded yet from django.db import models class profile(models.Model): n_id = models.IntegerField(primary_key=True, verbose_name='code melli') name = models.CharField(max_length=24, verbose_name='Full Name') class Meta: ordering = ('name',) class course(models.Model): name = models.CharField(max_length=24, verbose_name='Class Name') unit = models.SmallIntegerField() class Meta: ordering = ('name',) def __str__(self): return self.name class teacher(profile,models.Model): t_id = models.AutoField(primary_key=True) t_courses = models.ManyToManyField(course, verbose_name='Dars') def __str__(self): return self.name class student(profile,models.Model): s_id = models.AutoField(primary_key=True) s_courses = models.ManyToManyField(course, verbose_name='Dars') #teachers = ?????????????????????????? score = models.IntegerField(default=-1, verbose_name='Nomre') def __str__(self): return self.name I don't know about coding in the teachers part. Thanks alot -
