Question

I am trying to query a database within grails using:

            def per = User.get(springSecurityService.principal.id)
            def query = Post.whereAny {
                author { username == per.username }
            }.order 'dateCreated', 'desc'
            messages = query.list(max: 10)

My User is in a User domain and in the Post domain I have:

    String message
    User author
    Date dateCreated

when I run this query its empty every time my method in the controller for populating the database is:

  def updateStatus() {
         def status = new Post(message: params.message)
        System.out.println("test " + params.message)
            status.author = User.get(springSecurityService.principal.id)
        status.save()
    }

I am very new at quering databases in grails so if anyone could recommend some reading this would be good too.

Thanks

New version of spring-security-core plugin add methods to you controller, thus you can replace:

def per = User.get(springSecurityService.principal.id)
def query = Post.whereAny {
    author { username == per.username }
}.order 'dateCreated', 'desc'
messages = query.list(max: 10)

with

messages = Post.findAllByAuthor(principal, [sort: 'dateCreated', order 'desc', max: 10])

Without declaring springSecurityService

You can replace the updateStatus action with:

def updateStatus(){
    def status = new Post(message: params.message, author: principal)
    status.save()
}
