strip: If True and the input is a string, strip it (occurs before empty tests). if_invalid: If set, then this validator will raise Invalid during .to_python(); instead, return this value. if_invalid_python: If set, when the Python value (converted with .from_python()) is invalid, this value will be returned. accept_python: If True (the default), then .validate_python() and .validate_other() will not be called when .from_python() is used. The values of the configuration options are stored as class attributes. As an example, look at the DateConverter you used earlier. It is documented at http://formencode.org/class-formencode. validators.DateConverter.html, where you can see that the class has a number of attributes including month_style, which defaults to mm/dd/yyyy. There are two ways to set these attributes. The first is to pass the name of the attribute as an argument to the validator s constructor when you create it. You ve already seen an example of this technique when you passed not_empty=True to the DateConverter and EmailValidator validators in your schema. The other way to configure a validator is by using inheritance. You can create a new validator derived from the old one but with different default values for the attributes. As an example, here is a UKDateConverter, which uses the U.K. format for the date by default: class UKDateConverter(DateConverter): month_style = 'dd/mm/yyyy' You could then update your schema to look like this: class EmailForm(formencode.Schema): allow_extra_fields = True filter_extra_fields = True email = formencode.validators.Email(not_empty=True) date = UKDateConverter(not_empty=True) You ll learn more about creating your own validators later in this chapter.

Now that you have learned how to use FormEncode to validate and coerce data, you will still need to display error messages along with a repopulated form should the user have entered any invalid data. This is from the HTML Fill documentation: htmlfill is a library to fill out forms, both with default values and error messages. It s like a template library, but more limited, and it can be used with the output from other templates. It has no prerequesites and can be used without any other parts of FormEncode. The basic usage looks something like this: >>> from formencode import htmlfill >>> form = '<input type="text" name="fname">' >>> defaults = {'fname': 'Joe'} >>> htmlfill.render(form, defaults) '<input type="text" name="fname" value="Joe">' The parser looks for HTML input elements (including select and textarea) and fills in the defaults. HTML Fill is therefore very useful in processing forms because you can return the form to the user with the values they entered, in addition to errors.

Painter paths make it possible to draw any shape you want, but the trick is to define a path surrounding a region. You can then stroke the path with a given pen and brush. A path can contain several closed regions; for instance, it is possible to represent an entire text string using a path. The path shown in Figure 7-14 is created in three steps. First, the QPainterPath object is created and the circle is added using the addEllipse method. This ellipse forms one closed region. QPainterPath path; path.addEllipse( 80, 80, 80, 80 );

Instead, message authentication codes (MACs) are typically used to achieve message integrity in real-world security protocols. A MAC is not only a function of the message itself, but is also a function of a key known only to Alice and Bob, such that even if Mallory is able to modify the bytes of a message, she will not be able to appropriately modify the corresponding MAC. (MACs are covered in more detail in 15.) While the goal in confidentiality is to make sure that the contents of Alice and Bob s communication cannot be understood by a third party like Eve or Mallory, there is no such requirement for message integrity. For message integrity to be achieved, it does not matter whether the eavesdropper can see the data in the message so long as she is unable to change it undetected. The goal of message integrity is to make sure that even if Mallory can look, she cannot touch the contents of the message.

Let s update the controller to use HTML Fill. Change the submit() action to look like this: def submit(self): schema = EmailForm() try: c.form_result = schema.to_python(dict(request.params)) except formencode.Invalid, error: c.form_result = error.value c.form_errors = error.error_dict or {} html = render('/simpleform.html') return htmlfill.render( html, defaults=c.form_result, errors=c.form_errors ) else: return 'Your email is: %s and the date selected was %r.' % ( c.form_result['email'], c.form_result['date'], ) You ll also need to import HTML Fill. Add this import to the top of the controller: from formencode import htmlfill In this example, when an error occurs, you use Pylons render() function to render the HTML of the original form as it was before the user submitted it. You then pass the HTML, as well as the form result values and the error messages dictionary, into HTML Fill s render() method. HTML Fill then parses the HTML, adding any error messages and field values for you automatically. The filled HTML is then returned so that the user can correct the errors as before. Notice that you don t need the template code for the error messages and that none of the fields have values specified directly. HTML Fill populates the fields with the correct values and inserts any error messages automatically.
