python - TypeError at /datatable datatable() missing 1 required positional argument: 'file'

Question

In views.py

def datatable(request,file):
    csv_fp = open(f'csv_upload_files/{file}.csv', 'r')
    reader = csv.DictReader(csv_fp)
    headers = [col for col in reader.fieldnames]
    out = [row for row in reader]
    return render(request, 'result.html', {'data' : out, 'headers' : headers})

In urls.py

urlpatterns = [
    path('', views.upload,name='upload'),
    path('datatable',views.datatable,name='datatable')
]

I am unable to understand how to provide the saved csv file to the function datatable

Answer 1

You need to change your url for datatable, since the view takes a file parameter you need to add it in the url.

that's why it is giving you error for argument file missing

urlpatterns = [
    path('', views.upload,name='upload'),
    path('datatable/<str:file>',views.datatable,name='datatable')
]
