Single table's column can point to multiple table in django
Let's say I have tables FormulaA, FormulaB...FormulaX, and productContent. Formula { characteristicsA, characteristicsB, ... } Now, each product will be based on only a single formula(A to X). I want to design my database in such a way, that table productContent will have two columns, productContent { product_id, -> foreign key to product table formula_id -> can point to either of table formulaA,..formulaX } Now, My concerns/requirements are: if I have product_id, how can I get it's formula detail? Can I use select_related query here? we can take help of polymorphism, like make a common table, Formula, and from there formulaA,..formulaX can inherit. and in ProductContent table, we can have a new column, formula which will point to base table. But here also, how can I achieve requirement 1? -
django-channels: page not found

django sign up form not storing the username

Django/Celery 'Received unregistered task of type'
I have hit a brick wall for quite some time with my simple task that I need to run asynchronously from a Django server. I have a form on a page that when I submit a value my views.py executes a simple multiplication function from the tasks2.py file which also has my Celery stuff.

How to pass a nested foreignkey object to a another model?
I've been stumped for days; hoping one of you wizards can get me out of this pickle.. I have a model called ExtraSlot class ExtraSlot(models.Model): ....... employee = models.ForeignKey(Employee, on_delete = models.CASCADE, related_name="employee") this is the serializer class ExtraSlotSerializer(serializers.ModelSerializer): employee = EmployeeSerializer(many=True) <-- If I add this it tries to iterate through and errors out class Meta: model = WorkingSlot fields = (..... 'employee') fields = ('__all__') <- also used this to no avail depth = 3 I'm trying to add an Employee to the model; in the admin panel it is fine. The employee object can be selected. The DRF api doesn't show anything; I've read HTML list input isn't supported which is fine but the employee field as an input (even in raw format) doesn't show at all. Employee extends User (AbstractBaseUser) - here is the list error if I try many=true and passing the entire serializer. TypeError: 'Employee' object is not iterable (if I try pass EmployeeSerializer with many=True; which makes sense.) employee = EmployeeSerialzer() - passes the entire object as if I want to create a new one?! I want to allow a user to sign employee to the extraslot. Please help! -
DateField's DateInput widget with 'format="%B"' is not localized/translated
I'm trying to display a form-field with full month + Year representation (like 'December 2021') but I cannot localize it to German. In forms.py I'm using format("%B %Y") in the widget to achieve that representation, like so: date = DateField(widget=DateInput(attrs={"autocomplete": "off"}, format="%B %Y")) I'm using this form in an UpdateView, nothing fancy... <div class="form-row"> ... some fields <div class="form-group flatpickrdatetimeinput col-md-6 mb-0"> {{ form.date|as_crispy_field }} </div> </div> The date representation works in terms of Month + Year, but I need to localize the month name (December -> Dezember). I cannot find the error, I tried changing the field attribute (localize=True) and also I have played around with the settings (i18n, l10n, etc) with no success. In fact, the settings have worked out so far. In the same template I am using the 'date' template filter and it translates the month just fine <h2>{{campaign.date | date:'F Y' }}</h2> -

Question regarding a Django web app with firebase storage and heroku for deployment

When using Django's Default Storage should/can you close() an opened file?
When using Django's DefaultStorage it's possible to open and read a file something like this: from django.core.files.storage import default_storage file = default_storage.open("dir/file.txt", mode="rb") data = file.read() When using python's own open() method, it's best to close() the file afterwards, or use a with open("dir/file.txt") as file: construction. But reading the docs for Django's Storage classes, and browsing the source, I don't see a close() equivalent. So my questions are: Should a file opened with Django's Default Storage be closed? If so, how? If not, why isn't it necessary? -

Error __str__ returned non-string (type NoneType)
I know that this error is classic. But I'm facing a harder problem : This is my model. I've check all the topics about this common problem, try to resolve it but I don't achieved.

(Django) how to submit a form with empty fields?
I have a form with a drop down list with two options ("MCQ" and "SEQ") and some fields. Selecting "MCQ" would hide fields used by "SEQ" and vice versa. I want to submit this form but the "please filled out this field" notice pops up. What should I do to submit this form? I've searched around Stack overflow before looking possible solutions, some suggested placing "required" or "disabled" beforehand, however I would like a dynamic way of doing if possible but based it on which option the user selects since the user might leave everything empty and just submit if nothing is required. Additional Information: I'm using forms.ModelForm, the fields came from there. I'm using js to hide and show the relevant fields. I Appreciate any help/suggestions. :) -

Inside the React frontend, I am using react-router-dom to navigate between pages. I want to be able to click on a specific link, but then also pass on information to the component towards which the link is routed. This is my index.js code import React from 'react'; import ReactDOM from 'react-dom'; import './index.css'; import App from './App'; import reportWebVitals from './reportWebVitals'; import { BrowserRouter } from 'react-router-dom'; ReactDOM.render( <BrowserRouter> <App/> </BrowserRouter>, document.getElementById('root') ); This is my App.js code import './App.css'; import Container from '@material-ui/core/Container'; import Navigation from './Components/ToolBar' import Main from './Components/Main' function App() { return ( <> <Container maxWidth='lg' className="App"> <Navigation/> <Main/> </Container> </> ) } export default App; This is my Main.js code import { Switch, Route } from 'react-router-dom'; import Projects from './Projects'; import Tickets from './Tickets'; const Main = () => ( <Switch> <Route exact path='/projects' component={Projects}></Route> <Route exact path='/tickets' component={Tickets}></Route> </Switch> ); export default Main; This is my Toolbar.js code, which is used for navigating to different pages import { Button } from '@material-ui/core' import AppBar from '@material-ui/core/AppBar' import Toolbar … -
Parameterised decorator returning an error
I'm writing a decorator to check a certain attribute of a user. I will use this decorator over POST of GET methods of some class based APIs. The attribute is stored in the request.session["user_status']. def decorator_func(func): def wrapper_func(class_reference, request): status = request.session["user_status"] if status != value1 or status != value2: return Response(data="A dictionary") return func(class_reference, request) return wrapper_func Whenever the if condition is not satisfied and the func is accessed, it works as expected. But when the condition is satisfied and the Response() is returned, I'm getting following error: TypeError at "api path on which the decorator is applied" Object of type "custom user model of this project" is not JSON serializable I'm guessing due to not writing the decorator in the correct way I'm getting some error and when it is trying to return the error, it's also trying to return the current user object which is not JSON serializable. The user object is also stored in request.session["user"]. What am I doing wrong in this parameterized decorator function?
