What are the file upload limits in WTForms?
In WTForms, file upload limits can be set using the FileField
and FileRequired
validators. You can specify the maximum file size in your form validation.
How do I set a maximum file size for uploads?
You can use the FileAllowed
validator along with a custom validation function to check the file size. For example, you can define a function that raises a validation error if the file exceeds a certain size.
Can I restrict the types of files that can be uploaded?
Yes, you can restrict file types using the FileAllowed
validator, which allows you to specify a list of allowed file extensions.
What happens if a user tries to upload a file that exceeds the limit?
If a user tries to upload a file that exceeds the limit, the form will not validate, and an error message will be displayed to the user.
