Class RAccref

RAccref
A product key including possible modifiers.
The product key is in the accref attribute.
The modifiers come in the params dictionary. It contains (typed)
values, the possible keys of which are given in _buildKeys. The values
in passed in the inputDict constructor argument are parsed, anything not
in _buildKeys is discarded.
In principle, these modifiers are just the query part of a URL, and
they generally come from the arguments of a web request. However, we
don't want to carry around all request args, just those meant for product
generation.
One major reason for having this class is serialization into
URL-parts. Basically, stringifying a RAccref yields something that can be
pasted to <server root>/getproduct to yield the product URL. For
the path part, this means just percent-escaping blanks, plusses and
percents in the file name. The parameters are urlencoded and appended
with a question mark. This representation is be parsed by the fromString
function.
RAccrefs have a (read only) property productsRow attribute -- that's a
dictionary containing the row for accres from //products#products if that
exists. If it doesn't, accessing the property will raise an
NotFoundError.

Class Method
| source code
|
returns a rich accref from a path and a parse_qs-dictionary args.
(it's mainly a helper for fromRequest and fromString).
|
fromRequest(cls,
path,
request)
Class Method
| source code
|
returns a rich accref from a nevow request.
Basically, it raises an error if there's no key at all, it will return
a (string) accref if no processing is desired, and it will return a
RAccref if any processing is requested.
|
|
returns a fat product key from a string representation.
As a convenience, if keyString already is a RAccref, it is returned
unchanged.

returns True if the a preview generated for this rAccref is
representative for all representative rAccrefs.
Basically, scaled versions all have the same preview, cutouts do
not.

productsRow
returns the row in dc.products corresponding to this RAccref's accref,
or raises a NotFoundError.
- Get Method:
- unreachable.productsRow(self)
- returns the row in dc.products corresponding to this RAccref's accref, or
raises a NotFoundError.
