I'm fairly new to programming and basically I have no idea what I'm doing.
I'm trying to make a write simple UI that that can take an input and write it to a mongodb.
import pymongo
from tkinter import *
from tkinter import ttk
class Input:
def __init__(self, root,):
self.myclient = pymongo.MongoClient("mongodb://localhost:27017/")
self.mydb = self.myclient["mydatabase"]
self.mycol = self.mydb["input"]
title_label = Label(root, text="input")
title_label.grid(row=0, column=0, padx=10, pady=10, sticky=W)
self.input_value = StringVar(root, value="")
self.input = ttk.Entry(root, textvariable=self.input_value)
self.input.grid(row=0, column=1, padx=10, pady=10, sticky=W)
self.submit_button = ttk.Button(root,
text="Submit",
command=self.submit())
self.submit_button.grid(row=1, column=0,
padx=10, pady=10, sticky=W)
def submit(self):
entry = "input": self.input_value
self.mycol.insert(entry)
root = Tk()
In = Input(root)
root.mainloop()
When trying to run this I get
bson.errors.InvalidDocument: Cannot encode object: <tkinter.StringVar object at 0x000001EC62343908>
I tried converting input_value to 'normal' string
self.input_value = str(StringVar(root, value=""))
By doing that I get the program to run but whatever I input into the entry field it writes 'PY_VAR0' to the database.
What am I doing wrong?

Other way around. Rather than "assign a simple string" you need to coerceself.input_valueto a "simple string", or at least a valid type for the BSON serializer. So"input": str(self.input_value)

Thanks Neil Lunn.
entry = "input": self.input_value.get()
is now working using the get method.
Another problem I found is that I wrote
self.submit_button = ttk.Button(root,
text="Submit",
command=self.submit())
It actually needs to be
self.submit_button = ttk.Button(root,
text="Submit",
command=self.submit)
Without the parenthesis on self.submit.
Those caused the funktion to be executed at the start of the programm so it wrote empty strings even when using the get method.
