How to fix OS error at '/' Invalid Argument?
I have a django application that converts excel to csv files. This works fine but for larger files,it shows OSError at /conversion/ [Errno 22] Invalid argument: '<django.core.files.temp.TemporaryFile object at 0x000001C4C2C21A60>' I have successfully tested with converting smaller files but when I upload large files and try to process it, it shows the above error. views.py def conversion(request): excel_form = '' if request.method == 'POST': excel_form = ConversionForm(request.POST,request.FILES) if excel_form.is_valid(): excel_file = request.FILES['excel_file'].file df = pd.read_excel(excel_file) filename1 = excel_form.cleaned_data.get('excel_file').name filename1 = filename1.replace('.xlsx','') filename1 = filename1.replace('.xls','') df.to_csv(filename1 +'.csv',encoding='ascii',index=None, header=True) context = {'excel_form': excel_form, } return render(request,'colorlib-regform-6/convert_result.html',context) else: excel_form = ConversionForm() rontext = {'excel_form' : excel_form} return render(request,'colorlib-regform-6/convert_result.html',rontext) else: return render(request,'colorlib-regform-6/convert_result.html') -
Django Utils six for Django 3.1.5
I have a token generator that uses six from django.contrib.auth.tokens import PasswordResetTokenGenerator from django.utils import six class AccountActivationTokenGenerator(PasswordResetTokenGenerator): def _make_hash_value(self, user, timestamp): return ( six.text_type(user.pk) + six.text_type(timestamp) + six.text_type(user.is_active) ) account_activation_token = AccountActivationTokenGenerator() This runs on Django 2.2 but my boss told me to run this on latest 3.1.5. However, six was already depreciated. I also checked this SO suggestion https://stackoverflow.com/a/65620383/13933721 Saying to do pip install django-six then change from django.utils import six to import six I did the installation and changes to the code but it gives error message: ModuleNotFoundError: No module named 'six' I think I did something wrong or something is missing but I don't know how to proceed. Here is my pip freeze for reference asgiref==3.3.1 Django==3.1.5 django-six==1.0.4 djangorestframework==3.12.2 Pillow==8.1.0 pytz==2020.5 sqlparse==0.4.1 -
DjangoAdmin: How to get the Add/Edit/Del buttons for an `AutocompleteSelect` form field
I'm using the AutocompleteSelect widget for a ForeignKey field. To do this, you override the ModelForm class like so: class XForm(forms.ModelForm): ... x = forms.ModelChoiceField( queryset=X.objects.all(), widget=AutocompleteSelect(x.field.remote_field, admin.site) ) However, by using this widget I lose the ＋ ✎ ✕ buttons that are available on the Django Admin interface for a Foreign Key field by default. What will be a good way to use AutoCompleteSelect widget but also keeping these Add/Edit/Delete buttons besides the foreign key field on the Admin UI?
