Category: General Group: SQLObject from repository Status: Open Resolution: None Priority: 5 Private: No Submitted By: Leandro Lucarella (llucax) Assigned to: Nobody/Anonymous (nobody) Summary: [PATCH] TypeError:unhashable instance using sqlbuilder.Table Initial Comment: Hi! Maybe this is a pretty weird use case (please let me know if there is a better way to do this). What I wanted was just to store an ordered list of many-to-many relationships. To achieve this, I used an special intermediate table with an extra field for ordering. Then I write some custom SQL queries to do the join using sqlbuilder.table (Table instance) and friends. The problem is I'm getting a TypeError ("TypeError: unhashable instance") when doing that, because Table and Field don't have the __hash__ magic method (and for the records, none SQLExpression does either). Well, long story short, this is fixed by just adding the __hash__ method to SQLExpression class. Here is the patch and a simple testcase. Again, please tell me if there is a cleaner way to achieve this with SQLObject. Thanks! ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=540672&aid=1642143&group_id=74338 |
