"""
We can use AddFrom.applyData to save changes to a newly created
object.  The object doesn't yet need to have the attributes that are
going to be set on it.

  >>> getRootFolder()["zoo"] = Zoo()

  >>> from zope.testbrowser.wsgi import Browser
  >>> browser = Browser()
  >>> browser.handleErrors = False

AddForm.applyData() sends an IObjectModifiedEvent after having
modified the object.  Its return value is True in a Boolean sense when
the object has been modified:

  >>> browser.open("http://localhost/zoo/@@addmammoth")
  >>> browser.getControl(name="form.name").value = "Ellie the Mammoth"
  >>> browser.getControl(name="form.size").value = "Really small"
  >>> browser.getControl("Add entry").click()
  An IObjectModifiedEvent was sent for a mammoth with the following changes:
  IMammoth: name, size
  >>> print(browser.contents)
  There were changes according to applyData.

  >>> browser.open("http://localhost/zoo/ellie")
  >>> print(browser.contents)
  Hi, my name is Ellie the Mammoth, and I\'m "Really small"
