Best way to pass objects between controller actions in grails

Question

I want a link to open up another view in my webapp to display information about the specified object. What is the best way to pass objects between controllers actions in gra

Answer 1

(Late to the party, but...) I'm using Grails 2.4.4, which allows me to do the below:

def usernameLogin() {
  SecurityToken securityToken = authService.loginWithUserPass(params.user, params.pass)
  chain action: 'afterLogin', model: [securityToken: securityToken]
}

def ssoLogin() {
  SecurityToken securityToken = authService.ssoLogin(params.remoteUser, params.key)
  chain action: 'afterLogin', model: [securityToken: securityToken]
}

def afterLogin() {
  SecurityToken securityToken = (SecurityToken) chainModel['securityToken']
  if (securityToken.valid) {
    forward action: 'loggedInRedirect'
  }
  else {
    forward action: 'loginFailed'
  }
}

• SecurityToken is an object that contains string and enum
• The key is 1) using "chain action" in source action, 2) using chainModel in target action

Hope this helps.
