I am trying to validate the CSV input file, to ensure that the user is inputting the correct CSV file. However, I kept receiving the error AttributeError: PageOne instance has no attribute 'delete'. I can't seem to figure it out why.
Currently, when I input the correct/incorrect CSV file, popup will appear to tell me whether if I have input the correct file or not, but the code will not continue to file_entry.delete(0, tk.END) and the error AttributeError: PageOne instance has no attribute 'delete' appear.
Below are my codes for my Tkinter frame and the validation function.
class PageOne(tk.Frame):
def get_procurement_file(file_entry):
file_name = fd.askopenfilename(title="Select file", filetypes=(("CSV Files", "*.csv"),))
entry_file = file_name.split("/")[-1]
if entry_file == "government-procurement-via-gebiz.csv":
file_entry.popup_successinfo()
file_entry.delete(0, tk.END)
file_entry.insert(0, entry_file)
else:
file_entry.popup_errorinfo()
file_entry.delete(0, tk.END)
# file_entry.delete(0,END)
# file_entry.insert(0,file_name)
def get_contractor_file(file_entry):
file_name = fd.askopenfilename(title="Select file", filetypes=(("CSV Files", "*.csv"),))
entry_file = file_name.split("/")[-1]
if entry_file == "listing-of-registered-contractors.csv":
file_entry.popup_successinfo()
file_entry.delete(0, tk.END)
file_entry.insert(0, entry_file)
else:
file_entry.popup_errorinfo()
file_entry.delete(0, tk.END)
# file_entry.delete(0,END)
# file_entry.insert(0,file_name)
def popup_successinfo(self):
showinfo("Window", "Successfully input!")
def popup_errorinfo(self):
showinfo("Window", "Wrong input! Please insert the Correct File!")
