i have searched on stackoverflow to see if there are any question related but never find any except
these two questions

1st

2nd

Both of them recommend to check the database to ensure the database field matches the one declared in model

I had a look at my database and found the column named the same as in the model,
i don’t understand what really causing this error, so i didn’t get it and can’t solve this error pleeeease some help

Please copy/paste the complete model, the view where this error is occurring, and the traceback into a message. There’s not enough information here to provide any assistance.
