pandas read_excel from open file throws UnicodeDecodeError
I am trying to read data from excel to pandas. The file I get comes from api and is not saved (the access to the file needs special permissions, so I don't want to save it). When I try to read excel from file with open('path_to_file') as file: re = pd.read_excel(file) I get the error UnicodeDecodeError: 'utf-8' codec can't decode byte 0x98 in position 10: invalid start byte When I input path in palce of file everythng works fine re = pd.read_excel('path-to-exactly-the-same-file') Is there a way to read excel by pandas without saving it and inputting path? Thanks in advance! -

Django – Disabling ModelForm fields
How is it possible to disable certain ModelForm fields to indicate that they're not editable? The docs seem to suggest setting the widget to disabled should do the trick, including making it tamper-resistent, however doing that form validation fails as the disabled fields POST as empty. (also trying to use the has_changed method, but doesn't seem to work for ModelForms and no equivalent is provided...) I alternatively tried setting the clean_<fieldname> method on ModelForm level, to set the field to the referenced instance's value, but validation fails before that's reached. Some sample code: class MyForm(forms.ModelForm): class Meta: model = MyModel fields = '__all__' widgets = { 'slug': forms.TextInput(attrs={ 'disabled': True }) } def client_form(request, slug: str=None): instance = get_object_or_404(MyModel, slug=slug) form_myform = MyForm(request.POST or None, instance=instance) if request.method == 'POST': if form_myform.is_valid(): # fails, because slug is empty in POST request pass -

Does django-cors-headers prevent CORS latency issues?
I am developing a web application with Django backend and NextJS frontend. I am trying to have the frontend and the backend talk to each other and I am having some CORS issues. Reading about CORS I learned that it can introduce latency in large-scale apps because most requests basically have to be "processed" twice instead of once (correct me if I am wrong). To solve my CORS issues, I stumbled upon django-cors-headers and I was wondering whether this solution prevents latency among backend and allowed origins all together or not? Thanks.
