Things to watch out for in ColdFusion 9 with CF-ORM

Question

What are some of the things you\'ve observed in ColdFusion 9 with CF-ORM (Hibernate) that one should watch out for?

Answer 1

Add'l recommendations:

• Turn off ormsettings.flushAtRequestEnd = false to not have auto-flush at the end of the request. Instead use transactions (as of CF9.01, cftransaction flushes session for you transaction completion) around all write transactions (entitySave() or when you edit a persisted entity).
• Prevent SQL injection by using binded parameters in HQL - unnamed '?' or named ':' notations, to assure type binding by ORM against the field in question (like CFQUERYPARAM does). Prevent SQL injection!
• CF9.0.1 allows CFQUERY dbtype="hql" to write & output HQL inline. Use CFQUERYPARAM to bind params inline (equivalent to unnamed ? notation in HQL).
• Use LEFT OUTER JOIN FETCH in HQL to eager fetch relationships.
• Override add/remove functions on CFCs with bi-directional relationships to assure both sides are set when either is.
• Turn ormsettings.logsql=true to view derived SQL in the console. Adjust log4j Hibernate settings to further tweak log settings from Hibernate.
• Join Google Group cf-orm-dev. Bright people there.
