Suppose our current schema is `schema1`: {{{ CREATE TABLE `T1` ( `ACID` int(8) unsigned NOT NULL, `SITE` varchar(8) character set latin1 default NULL, CONSTRAINT `FK_T1_SITE` FOREIGN KEY (`SITE`) REFERENCES `schema2`.`site` (`SITE`) ) }}} For this situation, inspectdb will return something similar to this: {{{ _mysql_exceptions.ProgrammingError: (1146, ""Table 'schema1.site' doesn't exist"") }}} So it tries to use `schema1.site` as the table to introspect instead of the appropriate `schema2`.`site` Notice it not only needs to use the schema as part of the table name, but also not quote the '.'. Also, introspection.py was not pulling the schema name and just assuming the current schema, which for most cases is right, but in this case causes issues for legacy databases.
