- 3. Introduction A Grails plugin is a self-contained bundle of functionality that can be installed into a Grails application. When you install a Grails plugin, that plugin's functionality is made available to the installing application.
- 4. Console Console plugin provides a web-based Groovy console for interactive runtime application management and debugging. Dependency: compile "org.grails.plugins:console:1.5.7" plugins { runtime ':console:1.5.7' }
- 5. Console restricting access to localhost Ips: grails.plugin.springsecurity.controllerAnnotations.staticRules = [ "/console/**": ["hasRole('ROLE_ADMIN') && (hasIpAddress('127.0.0.1') || hasIpAddress('::1'))"], "/plugins/console*/**": ["hasRole('ROLE_ADMIN') && (hasIpAddress('127.0.0.1') || hasIpAddress('::1'))"] ]

- 8. DB Migration The Database Migration plugin helps you manage database changes while developing Grails applications. The plugin uses the Liquibase library. All of the scripts start with dbm- to ensure that they're unique , and don't clash with scripts from Grails or other plugins.
- 9. DB Migration Dependency: runtime "org.grails.plugins:database-migration:1.4.1" grails dbm-generate-changelog changelog.groovy grails-app/migrations/, you should see a file there called changelog.groovy Command: grails dbm-gorm-diff Config.groovy: grails.plugin.databasemigration.updateOnStart = true grails.plugin.databasemigration.updateOnStartFileNames = ['changelog.groovy']
- 10. DB Migration 1. To create a changelog from the database, use the dbm-generate-changelog script: grails dbm-generate-changelog changelog.groovy or grails dbm-generate-changelog changelog.xml 2. To create a changelog from your domain classes, use the dbm-generate-gorm-changelog script: grails dbm-generate-gorm-changelog changelog.groovy or grails dbm-generate-gorm-changelog changelog.xml 3. grails dbm-update
- 11. DB Migration grails dbm-gorm-diff 2012-02-01-initial-database.groovy --add databaseChangeLog = { include file: '2012-02-01-initial-database.groovy' }
- 13. Remote Pagination The remote-pagination plugin currently provides the following tags: remotePaginate remoteSortableColumn remotePageScroll remoteNonStopPageScroll
- 14. Remote Pagination <util:remotePaginate controller="book" action="filter" total="${Book.count()}" update="listTemplateDivId" max="20" pageSizes="[10, 20, 50,100]"/> <util:remotePaginate controller="book" action="filter" total="${Book.count()}" update="listTemplateDivId" max="20" pageSizes="[10:'10 Per Page', 20: '20 Per Page', 50:'50 Per Page',100:'100 Per Page']"/>
- 15. Asset Pipeline Plugin The Asset-Pipeline is a plugin used for managing and processing static assets in Grails applications. Asset-Pipeline functions include processing and minification of both CSS and JavaScript files. The asset-pipeline levereges the latest in minification (UglifyJS) to reduce your asset sizes as much as possible.
- 16. Asset Pipeline Plugin Dependency: compile "org.grails.plugins:asset-pipeline:2.11.0" Asset-Pipeline automatically creates a series of folders within your grails-app directory: grails-app/assets/javascript , grails-app/assets/images, grails-app/assets/stylesheets
- 17. Asset Pipeline Plugin Including Assets in your Views Asset pipeline provides several new tag libs for including javascript and css into your gsp files. Example: <head> <asset:javascript src="application.js"/> <asset:stylesheet href="application.css"/> </head>
- 18. Asset Pipeline Plugin NOTE: In development mode your stylesheets and javascripts will be included as individual script tags. This is intended to make it easier for debugging. Bundling is enabled in all other environments and can be forced in development mode by adding grails.assets.bundle=true to your Config.groovy. During war build your assets are also minified using UglifierJs. To disable this feature you can add the following option to your config: grails.assets.minifyJs = false
