IntegerFiled property can not pass the InputRequired or DataRequired validator when it is 0 about wtforms HOT 1 CLOSED

Can you provide a snippet demonstrating the bug you are referring to?

Here you can see that InputRequired passes the validation when the in put is 0.

>>> from werkzeug.datastructures import ImmutableMultiDict
>>> import wtforms
>>> class Form(wtforms.Form):
...     status1 = wtforms.IntegerField(validators=[wtforms.validators.DataRequired()])
...     status2 = wtforms.IntegerField(validators=[wtforms.validators.InputRequired()])
>>> f = Form(ImmutableMultiDict({"status1": "0", "status2": "0"}))
>>> f.validate()
False
>>> f.errors
{'status1': ['please enter the account status']}

The documentation explains this behavior:

Note there is a distinction between this and DataRequired in that InputRequired looks that form-input data was provided, and DataRequired looks at the post-coercion data. This means that this validator only checks whether non-empty data was sent, not whether non-empty data was coerced from that data. Initially populated data is not considered sent.
