fields added in Django View not displayed with django-crispy-forms
I have this view (modified to make it simple to understand): class MyCreateViewView(CreateView): model = SomeModel def get_form(self, form_class=None): form = super().get_form(form_class) form.helper = FormHelper(form) form.fields['additional_field'] = forms.BooleanField(label="Something", required=False) form.helper.add_input(Submit('submit', "Submit")) return form Before adding the FormHelper, the field additional_field appeared on the template. Now it doesn't. The form in my template is basically one line: {% crispy form %}. The django-crispy-forms docs don't show this approach because they are focused on using forms. I'm using the CreateView from Django that builds the form for me, so I don't need a form class. So far, I noticed that doing form.helper = FormHelper(form) after programmatically adding the new field solves the problem. But this is not a solution because the view I presented here is a simplified version, and I actually have two views that are doing something similar. So I'm inheriting this class and adding extra fields in the views themselves (meaning FormHelper is already there). -
Django Ckeditor: How to change background color/styling
I am having trouble changing the background color of the rich text editor. Most places say to edit the ckeditor css file but that isn't in my django project for the way i'm doing it i think. Is there a way to change it/add styles in the settings configs? or is there a better way to do this? template: <script type="text/javascript" src="ckeditor.js"> window.CKEDITOR_BASEPATH = '/static/ckeditor/ckeditor/'; CKEDITOR.replace( 'links' ); </script> settings file: CKEDITOR_CONFIGS = { 'default': { 'toolbar': 'Custom', 'toolbar_Custom': [ ['Link', 'Unlink'], ], 'height': 200, 'width': 750, 'stylesSet': [ { "name": 'Lead', "element": 'p', "attributes": {"margin-top": "10px"}, }, ], } } -
Django Rest Framework view doesn't work when called from DRF API tool
I have the following DRF ViewSet: class ServiceStatusForListViewSet(CustomModelViewSet): pagination_class = None permission_classes = (permissions.IsAuthenticated,) queryset = models.ServiceStatus.objects.all() serializer_class = serializers.ServiceStatusForListSerializer filter_backends = (DjangoFilterBackend, SearchFilter, OrderingFilter,) search_fields = ('service__item__product__name', 'service__client_name') filter_fields = ('id', 'service', 'service__item', 'service__item__product') This view works perfectly when a GET request is sent by a React frontend application, and it returns the expected response: The problem is when I send a GET request from the browser (Chrome): It just never returns, and the "loading" indicator keeps spinning forever. All other endpoints work well from DRF API tool, but this one. -
How can I loop the list into another loop in the Django template?
I need to loop a list into another loop without duplicating the results for example: {% for x in list1 %} {% for y in list2 %} {{ y }} {% endfor %} {% endfor %} I found half of the problem where I can call the elements of a list by a dot followed by the index number for instance: {{ iterator.0 }} {{ iterator.1 }} and that is succeded indeed however I took a little thinking where I thought that I could use: forloop.counter0 for looping but I couldn't use it I tried to use it like so: {{ iterator.forloop.counter0 }} but the trick didn't succeed. so, How can I loop easily into another loop? -
For loop in Django template causing error when I use the add filter
I am trying to add two variables together in my template that will combine two scores together and print the value. The problem is when the loop gets to a game that hasn't happened yet it kicks out an error because the variable doesn't exist yet. What am I supposed to add to skip games in the loop that have no score? {% for game in games %} <p class="light-blue text-center"> Total: {{ game.scoreboard.score.home|add:game.scoreboard.score.away }} </p> {% endfor %} -

create a model in django with conditions
I want to create an appointments model with Django, but with 2 conditions the first if the profile already exists than the appointments model use the information from the profile model, but if the profile dose doesn't exist than the user should fill the information in the appointments model this is my profile model class Profile(models.Model): GENDER_CHOICES = (('M', 'Male'), ('F', 'Female'),) user = models.OneToOneField(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) date_of_birth = models.DateField(blank=True, null=True) gender = models.CharField(max_length=1, choices=GENDER_CHOICES) phone_number = PhoneNumberField(blank=True) photo = models.ImageField(upload_to='users/%Y/%m/%d/', blank=True) def __str__(self): return f'Profile for user {self.user.username}' and this is my appointments model class Appointments(models.Model): GENDER_CHOICES = (('M', 'Male'), ('F', 'Female'),) user = models.OneToOneField(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) profile = models.OneToOneField(Profile, on_delete=models.CASCADE)# if profile dose not exist this will be none date_of_birth = models.DateField(blank=True, null=True)# and the user should fill this information gender = models.CharField(max_length=1, choices=GENDER_CHOICES) # and the user should fill this information phone_number = PhoneNumberField(blank=True)# and the user should fill this information date_time = models.DateTimeField() so if the one who wanted to make the appointments have already a profile the information about the gender and date of birth come from his profile if there is no profile the user should be fill those information -
Allowing user to rename the django model field names visible to him
I have a model like below. I want the user to be able to change the "external" field names (i.e. what is visible to the user) using some form of Legend (the internal field names should be the same: Product.rating1 should not change). The user opens the Product form he sees the default name of the fields (e.g. 'Rating 1' is called 'Rating 1'). But the user should be able to change this in a different form (e.g. 'Rating 1' to 'Some random name'). This new rating name should now be changed for all Products. class Product(models.Model): name = models.CharField(max_length=200) rating1 = models.IntegerField(default=0) rating2 = models.IntegerField(default=0) rating3 = models.IntegerField(default=0) class Legend(models.Model): rating1_name = models.CharField(max_length=200, default='Rating 1') rating1_abbr = models.CharField(max_length=2, default='R1') rating2_name = models.CharField(max_length=200, default='Rating 2') rating2_abbr = models.CharField(max_length=2, default='R2') rating3_name = models.CharField(max_length=200, default='Rating 3') rating3_abbr = models.CharField(max_length=2, default='R3') Desired result: The Product's database table will contain several products. However, the database table of Legend will just contain one entry that is created from the start (automatically) and it will never be deleted, the fields will just be changed. What I want is basically to in one place of my app have a form that creates these Products and another form … -
why do developers still create separate dashboard for login to perform CRUD functions instead of using the inbuilt Admin that is shipped by Django
I am a novice in Django I am just wondering why most developers would create separate dashboards to login and logout to perform all the CRUD functions. Why go through all that trouble instead of using the shipped Admin panel and create your users and assign permissions/roles to them to perform basically all the CRUD functions. -
Extract only the last 7 days of data in Python
If I have such data and I want to extract only the last 7 days of data, how can I do that? I tried to use Pandas examples, but I got errors such as module 'pandas' has no attribute 'example' or 'list' object has no attribute 'example', so I could not get the data for seven days. Also, I'm using React for the frontend. When processing data like this, is it best to do it on the frontend side or the backend side?

how do I send a text field input from the frontend to the backend
I have made a website, it uses react as the frontend and Django as the backend. I am trying to get an input from the frontend and send it to the backend, it doesn't seem to be working. here's the code: searchSong(e) { this.setState({ search: e.target.value }); console.log(this.state.search) } this is what takes the text field input : <TextField id="outlined-basic" label="Song" variant="outlined" value={this.state.search} onChange={this.searchSong} /> <Button variant="contained" color="secondary" onClick={this.addButtonPressed}>Search Song</Button> these are the functions that send the text input from the frontend to the backend and the states : addButtonPressed() { const requestOptions = { method: "POST", headers: { "Content-Type": "application/json" }, body: JSON.stringify({ search: this.state.search, }) }; fetch("/spotify/search-song/", requestOptions) } } searchSong(e) { this.setState({ search: e.target.value }); console.log(this.state.search) } the state : this.state = { search: "" } here's the function that I made which will test if I got the correct text field input : def search_song(session_id, song_name): search_letters = "playlist/?type=" + song_name print(search_letters) this is the view that uses the function : class SearchSong(APIView): lookup_url_kwarg = 'search' def post(self, request, format=None): if not request.session.exists(request.session.session_key): request.session.create() room_code = self.request.session.get(self.lookup_url_kwarg) music = str(request.data.get(self.lookup_url_kwarg)) room = Room.objects.filter(code=room_code)[0] search_song(room.host, music) this is the endpoint being called by the frontend : from … -
Django custom registration form html
New to Django and I am attempting to create a customer registration form and was successful. However the tutorial I followed showed me how to iterate through a loop, the contents of my registration_form which doesn't really give me much flexibility from a UI perspective, or so it seems. Can someone tell me how to customize this form based on the code I've got? HTML: <h1>This is the register.html</h1> <div class="col-md-4 offset-md-4"> <form method="post"> {% csrf_token %} {% for field in registration_form %} <p> {{field.label_tag}} {{field}} {% if field.help_text %} <small style="color: grey;">{{field.help_text}}</small> {% endif %} {% for error in field.errors %} <p style="color: grey;">{{error}}</p> {% endfor %} </p> {% endfor %} <button type="submit">Register</button> </form> </div> views.py def registration_view(request): context = {} if request.POST: form = RegistrationForm(request.POST) if form.is_valid(): form.save() email = form.cleaned_data.get('email') raw_password = form.cleaned_data.get('password1') account = authenticate(email=email, password=raw_password) login(request, account) return redirect('home') else: context['registration_form'] = form else: form = RegistrationForm() context['registration_form'] = form print(context) return render(request, 'accounts/register.html', context) forms.py class RegistrationForm(UserCreationForm): email = forms.EmailField(max_length=100, help_text='Required. Add a valid email address') class Meta: model = Account fields = ('email', 'username', 'password1', 'password2', 'first_name', 'last_name') the form renders and works fine with registration, just looks kinda crappy. thanks! -

Make a dang form field read only after initialised
I have a ModelForm in forms.py as follows: class OrderDetailForm(forms.ModelForm): class Meta: model = OrderDetails fields = ( 'OrderID', 'ProductCode', 'Location', 'UnitPrice', 'Quantity', 'Discount', ) def __init__(self, *args, **kwargs): super(OrderDetailForm, self).__init__(*args, **kwargs) locations = self.initial['ProductCode'].productqtys_set.values_list('Sublocation', flat=True) locationslist = list(locations) locationsQueryset = SubLocations.objects.filter(id__in=locationslist) print("locations queryset in form") print(locationsQueryset) self.fields['Location'].queryset = locationsQueryset In my views.py I have the function that uses it: def AddOrderDetail(request, pk): Product = Products.objects.get(ProductID=pk) order = Orders.objects.last() locations = Product.productqtys_set.all() if request.method == "POST": form = OrderDetailForm(request.POST, initial={"ProductCode": Product, "OrderID": order}) if form.is_valid(): form.save() return redirect('orders:subslistCreate') else: form = OrderDetailForm(initial={"ProductCode": Product, "OrderID": order}) template_path = 'orders/orderdetail_form.html' context = { "form": form, } return render(request, template_path, context) now as you can read, I initialised the ProductCode and OrderID fields, of course when it's time to fill in data for the other fields, the user can edit the values in ProductCode and OrderId. I don't want the user to be able to do that. I tried setting disabled to True but that didn't allow me to initialise the fields anymore, and I also tried to set readonly to true by adding the following lines in the definition of the init function: self.fields['OrderID'].widget.attrs['readonly'] = True self.fields['ProductCode'].widget.attrs['readonly'] = True sadly that changed … -

Django Templates Formsets with Foreign Key Lookup

Models.py class Profile(models.Model): user = models.OneToOneField(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) first_name = models.CharField(max_length=50, null=True, blank=True) last_name = models.CharField(max_length=50, null=True, blank=True) email = models.EmailField(max_length=254, null=True, blank=True) member_since = models.DateTimeField(auto_now_add=True) phone_number = PhoneNumberField(null=True, blank=True) street_address = models.CharField(max_length=50, null=True, blank=True) city = models.CharField(max_length=50, null=True, blank=True) country = models.CharField(max_length=50, null=True, blank=True) zip_code = models.IntegerField(null=True, blank=True) slug = models.SlugField(null=True, blank=True, unique=True) def __str__(self): return str(self.first_name) def get_phone_number(self): return self.phone_number @property def get_full_address(self): return f"{self.street_address}, {self.city}, {self.country}, {self.zip_code}" @receiver(user_signed_up) def populate_profile(sociallogin, user, **kwargs): user.profile = Profile() user_data = user.socialaccount_set.filter(provider='google')[0].extra_data first_name = user_data['given_name'] last_name = user_data['family_name'] email = user_data['email'] user.profile.first_name = first_name user.profile.last_name = last_name user.profile.email = email user.profile.save() def get_absolute_url(self): return reverse("profile", kwargs={"slug": self.slug}) def save(self, *args, **kwargs): self.slug = slugify("{obj.first_name}-{obj.last_name}".format(obj=self)) super(Profile, self).save(*args, **kwargs) Views.py class ProfileDetailView(LoginRequiredMixin, DetailView): model = Profile template_name = 'accounts/profile.html' Accounts Urls.py app_name = 'accounts' urlpatterns = [ path('profile/<slug>', ProfileDetailView.as_view(), name='profile') ] Main Urls.py from django.contrib import admin from django.urls import path, include urlpatterns = … -

Page keeps reloading after adding a new channels consumer and route
hope you all are doing well. I have been working on creating an asynchronous notification system, I already have a chat system but it is directed only towards the /inbox/ url. The problem that I'm facing is when I add a new consumer and access the home page the home page keeps reloading again and again and the terminal doesn't show any error. this is what my code looks like: Consumers.py async def websocket_connect(self,event): print("connected",event) await self.accept() async def websocket_receive(self,event): print("received",event) async def websocket_disconnect(self,event): print(event,"closed") class ChatConsumer(AsyncWebsocketConsumer): async def websocket_connect(self,event): print("connected") self.channel_layer = channels.layers.get_channel_layer() ..... await self.accept() async def websocket_receive(self,event): print("received2",event) ..... async def websocket_disconnect(self,event): print("disconnected",event) Routing.py from . import consumers from django.urls import re_path,path websocket_urlpatterns = [re_path(r"^a/inbox/(?P<username>[\w.@+-]+)", consumers.ChatConsumer.as_asgi()), re_path(r"a/(?P<username>[\w.@+-]+)",consumers.NotificationConsumer.as_asgi()), ] I'm trying to create a notifications websocket, any leads or any correction would be much appreciated. -
