• grails set bean value from radio button

  - by Jeff Storey

  I'm somewhat new to grails (not groovy though) and I'm working on a sample CRUD application. The issue I'm trying to solve is how to set a property on a bean based on a radio button before I update it in the database. Is the Form Helper http://www.grails.org/plugin/form-helper plugin the way to go? Will the bean have its value set regardless of if the button is actually clicked by the user or if it is left at its default value? thanks, Jeff

• Grails benchmarks compared to other web MVC platform (Rails, Django, ASP MVC)?

  - by fabien7474

  I have been searching the web for recent benchmarks measuring Grails overall performance compared to its competitors (Rails, Django, ASP.NET MVC...), but I didn't find anything more recent than a 3 years-old article with obsolete grails version (0.5). See here and here. So, starting from grails 1.2, are there any more recent grails benchmarks you are aware of ? Or do you have your own performance tests for grails (compared to others if possible) ?

• Protecting melody monitoring with acegi in grails

  - by xain

  Hi, I have a Grails 1.2 app secured with acegi that I'm monitoring with the melody plugin for grails. I need to protect the url so only the "admin" role can access it but I'm having trouble with it - the rest of the acegi rules work just fine. In the BootStrap, I set def secureReqMap = new Requestmap(url: '/monitoring/**', configAttribute:'ROLE_ADMIN').save() Also tried with def secureReqMap = new Requestmap(url: '/monitoring', configAttribute:'ROLE_ADMIN').save() With no luck, it keeps being public. Any hints? Thanks

• Can Grails output error messages in emacs format?

  - by ataylor

  Ant has a -e option for outputting error messages that can be parsed by emacs' compile command. For example, it is possible to do M-x compile, ant -e, then nagivate to any errors with C-x `. Is it possible to make grails output its compilation errors in this format? Alternatively, is there an emacs variable that can be customized to handle error messages in the format that grails uses?

• Grails exploded under tomcat

  - by xain

  Hi, is there a way to use Grails in "exploded" mode on tomcat in order to make individual changes in a running application (like a gif) without having to regenerate the entire war and upload it ? Something like adding an xml file in tomcat's conf/Catalina/localhost that points to an exploded grails application ? Thanks in advance.

• Best practice to modularise a large Grails app?

  - by Mulone

  Hi all, A Grails app I'm working on is becoming pretty big, and it would be good to refactor it into several modules, so that we don't have to redeploy the whole thing every time. In your opinion, what is the best practice to split a Grails app in several modules? In particular I'd like to create a package of domain classes + relevant services and use it in the app as a module. Is this possible? Is it possible to do it with plugins? Cheers, Mulone

• Using @Secured Annotation causes IS_FULLY_AUTHENTICATED problem in grails

  - by TripWired

  I'm using Acegi/Spring Security in grails and when i use the annotations like @Secured(['ROLE_ADMIN']) it denies my login even though the user is part of ROLE_ADMIN. In looking through the login is it seems that it's getting an IS_AUTHENTICATED_FULLY role also but I have never added that to a page so i'm not sure how to bypass that. I read somewhere to preauthorize the user, but i'm not sure how to do that with grails.

• Grails query not using GORM

  - by Tihom

  What is the best way to query for something without using GORM in grails? I have query that doesn't seem to fit in the GORM model, the query has a subquery and a computed field. I posted on stackoverflow already with no response so I decided to take a different approach. I want to query for something not using GORM within a grails application. Is there an easy way to get the connection and go through the result set?

• Modifying groovy code at runtime in grails application

  When I run my grails application using embedded jetty server(tomcat for grails 1.2), I can make changes to my controllers, services and other java files on-the-fly at runtime without restarting the application. How can I achieve the same functionality on my application deployed on Tomcat(or any server) for that matter. I have observed the exploded war folder under webapps has gsp files but not the groovy files.

• MS SQL Bridge Table Constraints

  - by greg

  Greetings - I have a table of Articles and a table of Categories. An Article can be used in many Categories, so I have created a table of ArticleCategories like this: BridgeID int (PK) ArticleID int CategoryID int Now, I want to create constraints/relationships such that the ArticleID-CategoryID combinations are unique AND that the IDs must exist in the respective primary key tables (Articles and Categories). I have tried using both VS2008 Server Explorer and Enterprise Manager (SQL-2005) to create the FK relationships, but the results always prevent Duplicate ArticleIDs in the bridge table, even though the CategoryID is different. I am pretty sure I am doing something obviously wrong, but I appear to have a mental block at this point. Can anyone tell me please how should this be done? Greaty appreciated!
