Grails: The DHTML JavaScript Date Picker

Grails Calendar (Date Picker) TagLib using ,The DHTML / JavaScript Calendar

http://www.dynarch.com/projects/calendar/

1. Download jscalendar-1.0.zip from http://www.dynarch.com/projects/calendar/
2. Extract the archive into {your-grails-app}/web-app/js/
3. rename directory name jscalendar-1.0 to calendar.
   Ex: {your-grails-app}/web-app/js/calendar/


4. Create a new tag library class
   source here
   

   see Contributed a Tag page on Grails
   
   

5. add calendar.select=Date Select in
   {your-grails-app}/grails-app/i18n/messages.properties for locale support
6. usage : replace <g:datePicker .... to <g:jsdatePicker ..... in edit.gsp and create.gsp
   

Using sequence in Grails GORM

Create a "hibernate.cfg.xml" file in the "%PROJECT_HOME%\hibernate" directory of your project,
or if you always want to use sequence in Grails
Checkout Grails from the SVN repository and
you will need to customize the part of the source:

Easier Way:
(fix just one source)
Do the following change.
source code of org.codehaus.groovy.grails.orm.hibernate.cfg.GrailsDomainBinder.java
at method bindSimpleId()
change

id.setIdentifierGeneratorStrategy( "native" );

to

id.setIdentifierGeneratorStrategy( "sequence" );

and add

params.setProperty(PersistentIdentifierGenerator.PK, "id");
params.setProperty("sequence", entity.getTable().getName() + "_id_seq");

just below of the

if ( mappings.getCatalogName() != null ) {
params.setProperty( PersistentIdentifierGenerator.CATALOG, mappings.getCatalogName() );
}

method bindSimpleId() will look like:

private static void bindSimpleId(GrailsDomainClassProperty identifier, RootClass entity, Mappings mappings) {

   // create the id value
   SimpleValue id = new SimpleValue(entity.getTable());
   // set identifier on entity
   entity.setIdentifier( id );
   // configure generator strategy
   id.setIdentifierGeneratorStrategy( "sequence" );// change here native to sequence

   Properties params = new Properties();

   if ( mappings.getSchemaName() != null ) {
       params.setProperty( PersistentIdentifierGenerator.SCHEMA, mappings.getSchemaName() );
   }
   if ( mappings.getCatalogName() != null ) {
       params.setProperty( PersistentIdentifierGenerator.CATALOG, mappings.getCatalogName() );
   }
   params.setProperty(PersistentIdentifierGenerator.PK, "id");//add here
   params.setProperty("sequence", entity.getTable().getName() + "_id_seq");//add here
   id.setIdentifierGeneratorProperties(params);

   // bind value
   bindSimpleValue(identifier, id, mappings );

   // create property
   Property prop = new Property();
   prop.setValue(id);

   // bind property
   bindProperty( identifier, prop, mappings );
   // set identifier property
   entity.setIdentifierProperty( prop );

   id.getTable().setIdentifierValue( id );

}

this always uses sequence at every tables (Domain class).
(sequence is supported on DB2,Oracle,PostgreSQL,Interbase,McKoi,SAP DB)
Check hibernate reference for more information:

hibernate mapping-declaration-id-generator



Harder way:
I fixed more code and add option like this on domain class:

def identifierGeneratorStrategy = "sequence"
//without this option domain class will use original
' IdentifierGeneratorStrategy( "native" ) '

Here is my diff:

Ruby on Railsに危険なセキュリティ・ホール

Ruby on Rails 1.1.4以前（1.1.4を含む）に危険なセキュリティ・ホールが見つかったらしい。
対策＝＞修正版であるバージョン1.1.5にアップデート

なお、詳細は非公表・・・・・え。。

セキュリティー関係ないが、Grailsは、SiteMeshの問題あるし・・・（この話は長くなる）・・・有る程度は、自分で直せるようにしておかないと、仕事で使えないか・・。
ただ、Grailsの場合は、Spring、Hibernate、SiteMeshにセキュリティーホールが有った場合も危険なので、その辺も完全安定するまでは、理解しておかないと。

フレームワーク使うときは、ちゃんと自分でもセキュリティーチェックを忘れないようにしよう＾＾；

Grails 0.2.1 公開

Grails 0.2 のいろいろ修正版
Grails 0.2.1が公開されました。
翻訳は、進んでません・・・
