        "description": "Crud\r\n====\r\n\r\nThis module gives you an abstract base class to make CRUD forms with.\r\nThese forms give you by default a tabular view of the objects, where\r\nattributes of the object can be edited in-place.  Please refer to the\r\n``ICrudForm`` interface for more details.\r\n\r\n  >>> from megrok.z3cform.crud import crud\r\n\r\nForm registration\r\n=================\r\n\r\nModels\r\n------\r\n\r\nWe set up some models to serve as a form context::\r\n\r\n  >>> import grokcore.component as grok\r\n  >>> from zope import interface, schema\r\n\r\n  >>> class IPerson(interface.Interface):\r\n  ...    name = schema.TextLine(title=u\"Name\")\r\n  ...    age = schema.Int(title=u\"Age\")\r\n\r\n  >>> class Person(grok.Context):\r\n  ...    grok.implements(IPerson)\r\n  ...    name = schema.fieldproperty.FieldProperty(IPerson['name'])\r\n  ...    age = schema.fieldproperty.FieldProperty(IPerson['age'])\r\n  ...\r\n  ...    def __init__(self, name, age):\r\n  ...        self.name = name\r\n  ...        self.age = age\r\n  \r\n  >>> class IPersonContainer(interface.Interface):\r\n  ...    pass\r\n  \r\n  >>> class PersonContainer(dict):\r\n  ...    grok.implements(IPersonContainer)\r\n\r\nFor this test, we take the the name of our persons as keys in our\r\nstorage:\r\n\r\n  >>> storage = PersonContainer()\r\n  >>> storage['Peter'] = Person(u'Peter', 16)\r\n  >>> storage['Martha'] = Person(u'Martha', 32)\r\n\r\nWe declare the Form with the help of megrok.z3cform.base. It's very similar to a grok.View::\r\n\r\n  >>> import megrok.z3cform.base as z3cform\r\n\r\n  >>> class TestForm(crud.CrudForm):\r\n  ...    grok.context(IPersonContainer)\r\n  ...\r\n  ...    update_schema = IPerson\r\n  ... \r\n  ...    def get_items(self):\r\n  ...        return sorted(storage.items(), key=lambda x: x[1].name)\r\n  ... \r\n  ...    def add(self, data):\r\n  ...        person = Person(**data)\r\n  ...        storage[str(person.name)] = person\r\n  ...        return person\r\n  ... \r\n  ...    def remove(self, (id, item)):\r\n  ...        del storage[id]\r\n\r\nGrokking and querying\r\n---------------------\r\n\r\nWe let Grok register the component::\r\n\r\n  >>> grok.testing.grok_component('form', TestForm)\r\n  True\r\n\r\nNow, we can query it normally::\r\n\r\n  >>> from zope.publisher.browser import TestRequest\r\n  >>> request = TestRequest()\r\n\r\n  >>> from zope.component import getMultiAdapter\r\n  >>> myform = getMultiAdapter((storage, request), name=\"testform\")\r\n\r\n  >>> myform\r\n  <TestForm object at ...>\r\n  >>> print myform()\r\n  <form action=\"http://127.0.0.1\" method=\"post\"\r\n          enctype=\"multipart/form-data\" class=\"form-testform\">\r\n  ...\r\n\r\nChangelog\r\n=========\r\n\r\n0.1\r\n---\r\n\r\n- Initial release",
