Thread: [SQLObject] Get Join instance for attribute

To work with foo = RelatedJoin('Song') we use .foo, .addSong and .removeSong. But those names are configurable. How do I get them when all I know is "foo"?

One way seems to be sqlmeta.joins[0].performJoin, .add and .remove. Is that an internal API, and subject to change? How do I get the list index?

Hi!

   I have less and less time to work on SQLObject so until someone
replaces me as the developer there will be no major changes for quite
some time.

   By looking up the join object you're interested in:

class Test1(SQLObject):
    test2 = RelatedJoin('Test2')

class Test2(SQLObject):
    test1 = RelatedJoin('Test1')

for j in Test2.sqlmeta.joins:
    print j.joinMethodName, j.otherClassName, j.addRemoveName
