Question

What is the best way to pass the model variables to layout in Grails? Specifically, I’m using Spring security plugin which has User class. I also have Contact class that looks like this:

class Contact {

    String realname
    String company
    String mobile
    String fix
    String email
    User user
        ...

What are the options for getting the currently logged in person’s company in my layout (main.gsp)?

Answer 1

To add to the above answer, you could alternatively set a session variable for the user when you login in whatever controller method gets called.

You can also just set a session variable for the company in the controller method:

session.company = Contact.findByUser(session.user)?.company

or from the example above

   session.company = Contact.findByUser(SecurityContextHolder.context.authentication?.principal)?.company

And in your main.gsp, something like:

<span id="companyName">${session.company}</span>
