Description

<type 'type'> extends (<class 'gluon.html.DIV'>,)


    example::

        >>> from validators import IS_NOT_EMPTY
        >>> form=FORM(INPUT(_name="test", requires=IS_NOT_EMPTY()))
        >>> form.xml()
        '<form action="" enctype="multipart/form-data" method="post"><input name="test" type="text" /></form>'

    a FORM is container for INPUT, TEXTAREA, SELECT and other helpers

    form has one important method::

        form.accepts(request.vars, session)

    if form is accepted (and all validators pass) form.vars contains the
    accepted vars, otherwise form.errors contains the errors.
    in case of errors the form is modified to present the errors to the user.
