gavo.web.adminrender module

A renderer to do RD-based maintenance.

class gavo.web.adminrender.AdminRenderer(request, service)

Bases: ResourceWithForm, CustomTemplateMixin, ServiceBasedPage

A renderer allowing to block and/or reload services.

This renderer could really be attached to any service since it does not call it, but it usually lives on //services/overview. It will always require authentication.

It takes the id of the RD to administer from the path segments following the renderer name.

By virtue of builtin vanity, you can reach the admin renderer at /seffe, and thus you can access /seffe/foo/q to administer the foo/q RD.

clientRD = None

customTemplate = <XMLFile of '/home/msdemlei/gavo/trunk/gavo/resources/templates/admin.html'>

data_blockstatus(request, tag)

data_services(request, tag)

returns a sequence of service items belonging to clientRD, sorted by id.

defaultLoader = <gavo.web.common.doctypedStan object>

exc(request, tag)

form_adminOps(request)

form_setDowntime(request)

getChild(name, request)

Retrieve a ‘child’ resource from me.

Implement this to create dynamic resource generation – resources which are always available may be registered with self.putChild().

This will not be called if the class-level variable ‘isLeaf’ is set in your subclass; instead, the ‘postpath’ attribute of the request will be left as a list of the remaining path elements.

For example, the URL /foo/bar/baz will normally be:

| site.resource.getChild('foo').getChild('bar').getChild('baz').

However, if the resource returned by ‘bar’ has isLeaf set to true, then the getChild call will never be made on it.

Parameters and return value have the same meaning and requirements as those defined by L{IResource.getChildWithDefault}.

ifexc(request, tag)

render children if there was an exception during RD load.

name = 'admin'

rdId(request, tag)

reloadExc = None

reloadRD(request, form, data)

reloadTB = None

render(request)

Render a given resource. See L{IResource}’s render method.

I delegate to methods of self with the form ‘render_METHOD’ where METHOD is the HTTP that was used to make the request. Examples: render_GET, render_HEAD, render_POST, and so on. Generally you should implement those methods instead of overriding this one.

render_METHOD methods are expected to return a byte string which will be the rendered page, unless the return value is C{server.NOT_DONE_YET}, in which case it is this class’s responsibility to write the results using C{request.write(data)} and then call C{request.finish()}.

Old code that overrides render() directly is likewise expected to return a byte string or NOT_DONE_YET.

setDowntime(request, form, data)

svclink(request, tag)

renders a link to a service info with a service title.

data must be an item returned from data_services.

toggleBlock(request, form, data)

traceback(request, tag)
