Node views

class nodular.view.NodeView(node, user=None, permissions=None)

Base class for node view handlers, to be initialized once per view render. Views are typically constructed like this:

class MyNodeView(NodeView):
    @NodeView.route('/')
    def index(self):
        return u'index view'

    @NodeView.route('/edit', methods=['GET', 'POST'])
    @NodeView.route('/', methods=['PUT'])
    @NodeView.requires_permission('edit', 'siteadmin')
    def edit(self):
        return u'edit view'

    @NodeView.route('/delete', methods=['GET', 'POST'])
    @NodeView.route('/', methods=['DELETE'])
    @NodeView.requires_permission('delete', 'siteadmin')
    def delete(self):
        return u'delete view'

Parameters:

• node (Node) – Node that we are rendering a view for.
• user – User that the view is being rendered for.
