Package com.avaje.ebean.validation Description

Annotations for validating entity beans.

We will look to migrate over to the standard java bean validation annotations.

You and put these annotations on entity beans and either get Ebean to automatically validate on Ebean.save() or manually validate using Ebean.validate().

It is possibly debatable if validation should be performed by an ORM rather than at a higher level in your application.

Even if you choose not to use these validation annotations the validation framework is in place and if you wish Ebean can automatically read the maximum lengths of all varchar columns (and not nullable constraints) from the database meta data. This is useful when using JDBC batching where the error reporting can be rather obscure (as the error could occur on any data in the batch).

   ## turn on automatic validation for Ebean.save()
   ebean.validation=true
  
   ## turn on automatic creation of not null validation
   ## and max length validation for varchar's based on 
   ## database meta data (no annotations required)
   ebean.validation.autocreate=true
   
   ## for more specific control... 
   ## 
   ## ebean.validation.autocreate.notnull=true
   ## ebean.validation.autocreate.length=true
   ## ebean.validation.autocreate.length.max=4000
   ## NB: Only auto create length validation for
   ## varchar columns less than 4000 characters
