Hello,
I wanted to revamp an in-house web application I had created using
erlyweb. I decided to try the latest versions of erlang, yaws and
erlyweb but sadly found that the mnesia support and the test suite
(!?!?) were broken. The attached patch was made against the latest svn
trunk and addresses the following issues:
- ./src/erlydb/erlydb_mnesia.erl
- as of 0.7 get_metadata/1 should return just a Tree structure but
was still returning a {ok,Tree} tuple.
- test/erlydb/erlydb_test.erl
- in the call to erlydb:code_gen/3 the order of the first two
arguments changed between 0.6 and 0.7!
- re-ordered the arguments to some component creation functions
(i.e. component:new/x where x is the record field count)
It appears that from erlyweb 0.7 the order of the arguments for the
component:new/x functions does not necessarily match the order of the
fields in the mnesia tables -- they appear to be in the order returned
by component:db_fields() -- it would seem to be less fragile to use
the component:new_with/1 function and name the arguments explicitly.
I've only tested against a mnesia database so I don't know how the
argument reordering mentioned above will affect the test run with a
mysql database but it does now run successfully with mnesia.
Best Regards,
John

Nice, thanks a lot. I've been maintaining only the MySQL driver and
unfortunately the Mnesia and Postgres drivers have fallen behind
somewhat. I appreciate the patch.
