Add Forms
---------

Set up user.

    >>> uf = app.site.acl_users
    >>> _ignored = uf._doAddUser('mgr', 'mgrpw', ['Manager'], [])

Create the browser object we'll be using.

    # BBB for Zope 2.12
    >>> try:
    ...     from Testing.testbrowser import Browser
    ... except ImportError:
    ...     from Products.Five.testbrowser import Browser

    >>> browser = Browser()
    >>> browser.handleErrors = False
    >>> browser.addHeader('Authorization', 'Basic mgr:mgrpw')

Register the content class and factory.

    >>> from Products.CMFDefault.formlib.tests import CONTENT_ZCML

    # BBB for Zope 2.12
    >>> try:
    ...     from Zope2.App import zcml
    ... except ImportError:
    ...     from Products.Five import zcml

    >>> zcml.load_string(CONTENT_ZCML)

Create the type info object.

    >>> from Products.CMFDefault.formlib.tests import MYFOO_XML
    >>> from Products.CMFDefault.formlib.tests import TYPES_XML
    >>> from Products.GenericSetup.context import SetupEnviron
    >>> from Products.GenericSetup.interfaces import IBody
    >>> from zope.component import getMultiAdapter

    >>> ttool = app.site.portal_types
    >>> context = SetupEnviron()
    >>> context._should_purge = False
    >>> importer = getMultiAdapter((ttool, context), IBody)
    >>> importer.body = TYPES_XML
    >>> importer = getMultiAdapter((ttool.MyFoo, context), IBody)
    >>> importer.body = MYFOO_XML

If no add view is registered for 'test.foo' the fallback add view is used. It
just has an ID field.

    >>> browser.open('http://localhost/site/++add++MyFoo')
    >>> '[[cmf_default][Add [[cmf_default][MyFoo]]]]' in browser.contents
    True
    >>> browser.getControl(name='form.bar')
    Traceback (most recent call last):
    ...
    LookupError: name 'form.bar'
    >>> browser.getControl(name='form.id').value = 'MY_ID'
    >>> browser.getControl('[[zope][Add]]').click()
    >>> '[[cmf_default][[[cmf_default][MyFoo]] added.]]' in browser.contents
    True
    >>> 'MY_ID' in app.site.contentIds()
    True

This is the most simple add form you can create for 'test.foo'. Add views
always belong to specific content factories. The name of the factory and the
name of the add view have to be the same.

    >>> from zope.component import getSiteManager
    >>> from zope.formlib import form
    >>> from Products.CMFDefault.formlib.form import ContentAddFormBase
    >>> from Products.CMFDefault.formlib.tests import IFoo

    >>> class FooAddView(ContentAddFormBase):
    ...     form_fields = form.FormFields(IFoo)
    >>> getSiteManager().registerAdapter(FooAddView, name='test.foo')

The customized add form has the same title but no ID field. On the other hand
it has the fields defined in IFoo.

    >>> browser.open('http://localhost/site/++add++MyFoo')
    >>> '[[cmf_default][Add [[cmf_default][MyFoo]]]]' in browser.contents
    True
    >>> browser.getControl(name='form.id')
    Traceback (most recent call last):
    ...
    LookupError: name 'form.id'
    >>> browser.getControl(name='form.bar').value = 'BAR'
    >>> browser.getControl(name='form.baz').value = 'BAZ'
    >>> browser.getControl('[[zope][Add]]').click()
    >>> '[[cmf_default][[[cmf_default][MyFoo]] added.]]' in browser.contents
    True
    >>> 'Foo' in app.site.contentIds()
    True

Now we add again the ID field.

    >>> from Products.CMFDefault.formlib.widgets import IDInputWidget
    >>> from Products.CMFDefault.utils import Message as _
    >>> from zope.schema import ASCIILine

    >>> class FooAddView(ContentAddFormBase):
    ...     form_fields = (
    ...         form.FormFields(ASCIILine(__name__='id', title=_(u'ID'))) +
    ...         form.FormFields(IFoo)
    ...         )
    ...     form_fields['id'].custom_widget = IDInputWidget
    >>> getSiteManager().registerAdapter(FooAddView, name='test.foo')

The customized add form has the ID field and the fields defined in IFoo.

    >>> browser.open('http://localhost/site/++add++MyFoo')
    >>> '[[cmf_default][Add [[cmf_default][MyFoo]]]]' in browser.contents
    True
    >>> browser.getControl(name='form.id').value = 'MY_ID2'
    >>> browser.getControl(name='form.bar').value = 'BAR'
    >>> browser.getControl(name='form.baz').value = 'BAZ'
    >>> browser.getControl('[[zope][Add]]').click()
    >>> '[[cmf_default][[[cmf_default][MyFoo]] added.]]' in browser.contents
    True
    >>> 'MY_ID2' in app.site.contentIds()
    True
