Detailed Description

This action implements a sensible default end action, which will forward to the first available View or a custom one, unless c->res()->status() is a 3xx code (redirection, not modified, etc.), 204 (no content), HEAD methods, or c->res()->body() has already been set.

If you have more than one view, you can specify which one to use with the :View(name) attribute or one set with c->setCustomView() otherwise this module simply calls c->view() with no argument what will return the default View.

The RenderView action allows to easily call a renderer without including it’s header and add implementation code, all that is needed is an annotation to the Controller’s method:

class Users : public Cutelyst::Controller
{
public:
C_ATTR(End, :ActionClass(RenderView))
void End(Context *c);
};
Cutelyst Controller base class.
Definition: controller.h:56
RenderView(QObject *parent=nullptr)
Definition: renderview.cpp:58

The above will render with the default view added to Cutelyst::Application without a name, if you want it to render with another view just add the View(name) keyword:

...
C_ATTR(End, :ActionClass(RenderView) :View(ajax_view))
void End(Context *c);
...

Constructor & Destructor Documentation

◆ RenderView()

RenderView::RenderView ( QObject parent = nullptr)
explicit

Constructs a RenderView object with the given parent.

Definition at line 58 of file renderview.cpp.

References Cutelyst::Action::className(), QString::fromLatin1(), QObject::metaObject(), and QObject::setObjectName().

Member Function Documentation

◆ doExecute()

bool RenderView::doExecute ( Cutelyst::Context c)
overrideprotectedvirtual

This will forward execution to either a custom view or to a view set as method attribute via :View(name) or to the default view.

If the Content-Type header of the Response has not been already set, it will be set to 'text/html; charset=utf-8'.

If the Request is a HEAD request or if the Response::body() has already been set, this will do nothing and will return true. The same is true for when the Response::status() has already been set to 204 (no content) or 3xx.

◆ init()

bool RenderView::init ( Cutelyst::Application application,
const QVariantHash &  args 
)
overridevirtual

Initializes the RenderView action by looking for a view name in the method attributes. The default view will be used if no :View(name) has been declard on the method attributes.
