Precautions

PostgreSQL is a great DBMS with lots of features. DataDrivenInputMask does not claim to support all of them, nor is it the plugin's goal to do so. That being said here is a list of things that you should follow when working with DataDrivenInputMask:

• no spaces in names (of schemas, relations, fields)
• no non-ascii characters in names (of schemas, relations, fields), although this may work
• no primary keys consisting of multiple fields, except in relation tables, see Widgets-for-n-2-m-Relations. One-field primary keys, preferably integer or similar (smallint, bigint) are recommended instead.
• check constraints are ignored, therefore input not following a check constraint is sent to the DB (use the Configuration-of-masks instead).
