I'm trying to delete a record when the ID is inserted or the Name of the Recipe is entered by the user into the entry boxes. However it will not let me obtain the information from the entry box due to the following error:
"Traceback (most recent call last):
File "C:\Python33\lib\tkinter\__init__.py", line 1475, in __call__
return self.func(*args)
File "H:\A-Level Computing\PROJECT!\Final Code.py", line 368, in delete_recipe
Retrieve1 = EntryBox1.get()
AttributeError: 'NoneType' object has no attribute 'get'"
The code is as follows:
def delete_recipe():
global EntryBox1, EntryBox2, new_db
Retrieve1 = EntryBox1.get()
Retrieve2 = EntryBox2.get()
new_db = sqlite3.connect('H:\A-Level Computing\PROJECT!\Recipes.db')
new_db.execute("DELETE from RecipesDetails WHERE Retrieve1 = Rec_ID and Retrieve2 = Name")
new_db.commit()
new_db.close()
I would be really grateful for any help;. Thanks!
Make sure you don't have a line like the following:
entry = Entry().pack() # entry is None
pack
, grid
, place
does return None
. entry
become None
.
You should separate the Entry
creatation and call to pack
/ grid
/ place
method:
entry = Entry()
entry.pack()
