Question

I can’t seem to figure out what is wrong.
While using plays framework CRUD module to insert information into DB (mySql)
(I am using the default module insertion mechanism as shown at http://www.playframework.org/documentation/1.0.1/crud)
I receive the following exception

PersistenceException occured :
org.hibernate.exception.GenericJDBCException: could not insert:
[models.Mail]

In {module:crud}/app/controllers/CRUD.java (around line 152)

             } catch (TemplateNotFoundException e) {
                 render("CRUD/blank.html", type, object);
             }

          } 

  Here -> object._save(); 
          flash.success(play.i18n.Messages.get("crud.created", type.modelName)); 
         if (params.get("_save") != null) { 
             redirect(request.controller + ".list"); 
          } 
          if (params.get("_saveAndAddAnother") != null) { 

         redirect(req

uest.controller + ".blank");

here is my mail entity class:

@Entity
public class Mail extends Model {


   public String title;

   public Date sentAt;
   @OneToMany
   public Set<User> sentTO;
   @OneToMany
   public Set<User> sentBCC;


    public String content;

    @ManyToOne
    public User author;

    public Mail(User author, ... ){

      //more code here
    }

}

controller

package controllers;

/**
 *
 * @author mike
 */
public class Mails extends CRUD{

}

any ideas?

Answer 1

See the actual cause

Caused by: java.sql.SQLException: Field 'isAdmin' doesn't have a default value

Looks like you’re trying to save into a row without setting the isAdmin property (which is also not defined in your model, but might be in your actual database?).
