symfony: trying to create a patch. What should be my first step(s)?

i created this ticked some days ago.

http://trac.symfony-project.org/ticket/8922#preview

I'm interested in creating a p开发者_运维知识库atch (if possible). I dont have experience debugging (just using var_dump). What should be my first step(s) ?

Why do you want to create a patch? Do you want to fix your problem and publish the solution? If so than patches are usually created with a diff tool: http://stephenjungels.com/jungels.net/articles/diff-patch-ten-minutes.html

About your problem: you extend sfGuardUser class and add slug to the child table. Why do you expect that it shows up in the parent? It's not how inheritance works.
