Gooey 1.0.8.1 Validation Not Working

[Kian Khadempour]

• OS: Windows 10 Home 22H2
• Python Version: 3.11.4
• Gooey Version: 1.0.8.1
• Thorough description of problem:
  Here is my code:

def is_date_valid(date_to_validate: str) -> bool:
    try:
        datetime.datetime.strptime(date_to_validate, "%Y-%m-%d")
    except:
        return False
    return True

#...

@Gooey(
    program_name="...",
    disable_stop_button=True,
)
def main():
    parser = GooeyParser(
        description="...",
    )

    #...

    parser.add_argument(
        #...

        widget="DateChooser",
        gooey_options={
            "validator": {
                "test": "is_date_valid(user_input)",
                "message": "Please enter the date in the correct format (use the Choose date button)",
            }
        },
    )

    #...

• Expected Behavior: When inputting the value "2023-06-22", the program should run and not display the message.
• Actual Behavior: The programs does not run and displays the message.
• A minimal code example -- preferably copy/pastable in the issue itself (less time figuring out how to run your code == more time debugging!): Already submitted.
• Screenshot (if visual quirk): N/A
• Anything else you may think will be helpful: The date format is YYYY-MM-DD (padded)

Hi, I didn't test your code, but it looks like you forgot to enable the Dynamic Validation functionality. Take a look at relevant section in README: Dynamic Validation, especially the How to enable the pre-flight validation subsection. You have to tell Gooey to use the VALIDATE_FORM event.

This was in version 1.0.8, where validation is supposed to (I think) look like this, but I will switch to the 1.2 Alpha if I ever want validation again.
