Known Subclasses:

A mixin with renderers useful throughout the data center.

Rendering of meta information:

<tag n:render="meta">METAKEY</tag> or
<tag n:render="metahtml">METAKEY</tag>

Rendering the sidebar -- <body n:render="withsidebar">. This will only work if the renderer has a service attribute that's enough of a service (i.e., carries meta and knows how to generate URLs).

Conditional rendering:

ifmeta
imownmeta
ifdata
ifnodata
ifslot
ifnoslot
ifadmin

Obtaining system info

rd <rdId> -- makes the referenced RD the current data (this is not too useful right now, but it lets you check of the existence of RDs already)

Instance Methods

data_meta(self, metaKey)
returns the value for the meta key metaName on this service.

source code

render_meta(self, ctx, data)
replaces a meta key with a plain text rendering of the metadata in the service.

source code

render_metahtml(self, ctx, data)
replaces a meta key with an html rendering of the metadata in the serivce.

source code

render_datameta(self, ctx, data)
replaces the meta key in the contents with the corresponding meta key's HTML rendering.

source code

render_ifmeta(self, metaName, propagate=True)
renders its children if there is metadata for metaName.

source code

render_ifownmeta(self, metaName)
renders its children if there is metadata for metaName in the service itself.

source code

render_ifdata(self, ctx, data)

source code

render_ifnodata(self, ctx, data)

source code

render_ifslot(self, slotName)
renders the children for slotName is present and true.

source code

render_ifnoslot(self, slotName)
renders if slotName is missing or not true.

source code

render_ifadmin(self, ctx, data)

source code

render_explodableMeta(self, ctx, data)

source code

render_intro(self, ctx, data)
returns something suitable for inclusion above the form.

source code

render_authinfo(self, ctx, data)

source code

render_prependsite(self, ctx, data)
prepends a site id to the body.

source code

render_withsidebar(self, ctx, data)

source code

data_rd(self, rdId)
returns the RD referenced in the body (or None if the RD is not there)

Method Details

render_ifslot(self, slotName)

source code

renders the children for slotName is present and true.

This will not work properly if the slot values come from a deferred.

render_ifnoslot(self, slotName)

source code

renders if slotName is missing or not true.

This will not work properly if the slot values come from a deferred.

render_intro(self, ctx, data)

source code

returns something suitable for inclusion above the form.

The renderer tries, in sequence, to retrieve a meta called _intro, the description meta, or nothing.

render_prependsite(self, ctx, data)

source code

prepends a site id to the body.

This is intended for titles and similar; it puts the string in [web]sitename in front of anything that already is in ctx.tag.

provides(...)

Special descriptor for class __provides__

The descriptor caches the implementedBy info, so that we can get declarations for objects without instance-specific interfaces a bit quicker.

Overrides: common.CommonRenderers.__provides__
