Contact information form and view

In order to put all the pieces described in this sub-section together, we need the following:

• A view to render the sub-forms needed to collect contact information.
• View logic to capture and validate form post data.
• A template to incorporate the sub-forms and JavaScript functions.
• A domain service to update the properties collection.

A new view method, updateContact(), in /path/to/repo/www/chapter_08/property/views.py, creates instances of the form service described in the previous sub-section. In addition, it retrieves instances of both the partner and property domain services. The check variable represents the number of validation checks to be performed:

def updateContact(request) :
    formSvc = FormService()
    message = ''
    config  = Config()
    partSvc = PartnerService(config)
    propSvc = PropertyService(config)
    check   = 4

We then define a sequence of validation checks to be performed if the request method is POST...
