        "description": "more.body_model: ``load_json`` infrastructure for Morepath\n==========================================================\n\nThe idea is to recognize on an application-level what kind of JSON content\nis being posted, and convert it into a Python object. You can use this\napplication object with ``request.body_obj``. With ``body_model`` you can\nthen write views that specifically match that kind model.\n\nTo use it you have to subclass your application from\n``more.body_model.BodyModelApp``:\n\n.. code-block:: python\n\n  from more.body_model import BodyModelApp\n\n  class App(BodyModelApp):\n      pass\n\n.. note:: If you want to use body_model on a mounted App, make sure that both,\nthe base App and the mounted App are a subclass from\n``more.body_model.BodyModelApp``. Otherwise it will not work.\n\n\nload_json\n---------\n\nThe ``App.load_json`` directive lets you define a function that turns\nincoming JSON into a Python object. This behavior is shared by all views in the\napplication. We detect JSON with the type field ``Item`` and interpret it as an\n``Item`` instance, and pass through everything else:\n\n.. code-block:: python\n\n  @App.load_json()\n  def load_json(json, request):\n      if json.get('type') != 'Item':\n          return json\n      return Item(json['x'])\n\nWhen you write a ``json`` view you automatically get the ``Item``\ninstance as the ``body_obj`` attribute of the ``request``:\n\n.. code-block:: python\n\n  @App.json(model=Collection, request_method='POST')\n  def collection_post(self, request):\n      collection.add(request.body_obj)\n      return \"success!\"\n\nYou can write views that match on the class of ``body_obj`` by specifying\n``body_model``:\n\n.. code-block:: python\n\n  @App.json(model=Collection, request_method='POST', body_model=Item)\n  def collection_post_item(self, request):\n      collection.add(request.body_obj)\n      return \"success!\"\n\n\nbody_model\n----------\n\nTo define JSON body conversion code generally for an application we can use\n``App.load_json``:\n\n.. code-block:: python\n\n  @App.load_json()\n  def load_json(json, request):\n     if is_valid_document_json(json):\n        return Document(title=json['title'],\n                        author=json['author'],\n                        content=json['content'])\n     # fallback, just return plain JSON\n     return json\n\nNow we get a ``Document`` instance in ``Request.body_obj``, so\nwe can simplify ``document_collection_post``:\n\n.. code-block:: python\n\n  @App.json(model=DocumentCollection, request_method='POST')\n  def document_collection_post(self, request):\n      if not isinstance(request.body_obj, Document):\n         raise webob.exc.HTTPUnprocessableEntity()\n      result = self.add(request.body_obj)\n      return request.view(result)\n\nTo only match if ``body_obj`` is an instance of ``Document`` we can\nuse ``body_model`` on the view instead:\n\n.. code-block:: python\n\n  @App.json(model=DocumentCollection, request_method='POST', body_model=Document)\n  def document_collection_post(self, request):\n      result = self.add(request.body_obj)\n      return request.view(result)\n\nNow you get the ``422`` error for free if no matching ``body_model``\ncan be found. You can also create additional ``POST`` views for\n``DocumentCollection`` that handle other types of JSON content this\nway.\n\n\nCHANGES\n=======\n\n0.1 (2017-03-17)\n----------------\n\n* initial public release.",
