mythfilldatabase incorrectly parses "rating" in XMLTV

Reported by: Max Barry Owned by: danielk
Priority: minor Milestone: 0.21
Component: mythtv Version: 0.20
Severity: low Keywords: mythfilldatabase xmltv
Cc: Ticket locked: no


XMLTV can include multiple <rating> tags for a single program, for example:

  <programme ...
     <rating system="ABA">
     <rating system="advisory">
       <value>Adult Themes</value>
     <rating system="advisory">
     <rating system="advisory">
       <value>Drug Use</value>

mythfilldatabase tries to concatenate these together, but the database schema allows only 8 characters. The result is that the rating for this program in MythTV looks like this: "Adult th".

From {mythtv}/programs/mythfilldatabase/filldata.cpp:

                // again, the structure of ratings seems poorly represented
                // in the XML.  no idea what we'd do with multiple values.

                ProgRating rating;
                rating.system = info.attribute("system", "");
                rating.rating = getFirstText(item);
                if ("" != rating.system)

... and from the mythconverg.programrating table:

      rating                   CHAR(8) NOT NULL

Ideally, MythTV should be able to display the rating as: "(M) Adult Themes, Violence, Drug Use". Failing that, mythfilldatabase should probably drop ratings using the "advisory" system when there's an alternative present, since "M" is more informative than "Adult Th".

I'm planning to look at this code soon for EIT fixes...

If you change the rating string to 16 characters then the DB info is correct, right?

At that point it should just a problem with what gets show in the UI, we could add a preference for showing a non-advisory rating first.. In what part of the UI are you seeing the rating? (I can see the program details text in ProgramInfo::showDetails(void) is only showing one rating, but if there are other broken screens..)

(In [11620]) Refs #2567. Fixes the ProgramInfo::showDetails() ratings string.

showDetails was only showing the first ratings string that showed up in the ratings query, but often this is just one of the advisory ratings, rather than something more important like the VChip or MPAA rating. This changeset adds a static function which creates concatinates the ratings strings with the advisory ratings always appearing after the VChip, MPAA, ABA, and similar ratings systems.

Resolution: fixed
Status: newclosed

(In [11663]) Fixes #2567. Extends the rating column in recordedrating and programrating from 8 to 16 characters to support longer advisory ratings such as 'Adult Themes'
