I need to know how to take info from the user in one page using a label and textfield and displaying that in a grid in another page.
For example, Im getting the name of the user and displaying their name in following page in a grid. I'm using eclipse and working with vaadin, if that helps.
if what you need is an info from connected user, I suggest you to set the User object as Session Attribute.
IE:
User connectedUser = new User();
VaadinSession.getCurrent().setAttribute(User.class, connectedUser);
Then, if you need to pick this information, you just have to call
User currentUser = (User) VaadinSession.getCurrent().getAttribute(User.class);
Then, you can pick with all your getter all the required infos, like
String username = currentUser.getUsername();
In my opinion the best approach is to set the user attribute after his login, so you can have it everywhere you need to pick it from any class of your Vaadin application.
Hope this helps.
Bye

What I need is to redirect a User to a new "home page" with data taken from form input that the user would have entered before clicking the submit button.
For example (but not what is exactly required): if a form asks the user Bob to enter data about himself, when Bob submits the form he will be taken to a new formatted page example.com/bob with all the information he entered.
A new jsp page would not be created, but somehow I need the controller to take the url and search the database for the user "Bob" and format the directed page with all Bob's information.
You can use a url like example.com/bob using path variables.
In your controller you need something like this:
#RequestMapping("/{name}")
public String userDetails(#PathVariable String name){
// retrieve user details from DB by username
return "redirect:/" + name;
}
Take a look at Spring MVC docs.
User userFind = userMetier.getUserByEmail(user.getEmail);
Return "home2.html?name="+userFind.getName()+"?email="+userFind.getEmail() ;
I've successfully added a custom field to the User Sign-up page (create_account.jsp) by creating an expando column via Hook plugin. However, the field is not visible until I enable Guest permissions on it through the admin UI.
I need to be able to do this programmatically, through the Hook plugin. Exhaustive research leads me to believe that the following code should do the trick:
Role guest = RoleLocalServiceUtil.getRole(companyId, RoleConstants.GUEST);
ResourcePermissionLocalServiceUtil.setResourcePermissions(
companyId,
ExpandoColumn.class.getName(),
ResourceConstants.SCOPE_INDIVIDUAL,
String.valueOf(expandoColumn.getColumnId()),
guest.getRoleId(),
new String[] { ActionKeys.VIEW, ActionKeys.UPDATE });
But it doesn't.
Anyone got any ideas?
I tried same code as yours and it worked for me. In my opinion the problem is in "expandoColumn.getColumnId()". How do you retreive object ExpandoColumn? I tried with with table id and name:
ExpandoColumn expandoColumn = ExpandoColumnLocalServiceUtil.getColumn(21806, "Menu");
For this try i retreive the table id directly from DataBase, from table "expandocolumn"
I need to assign roles to my Liferay's users when they log in the application.
I have implemented all the logic in the 'authenticateByScreenName' method of a custom class that implements 'Authenticator'.
Example code:
public class ESBAuthenticator implements Authenticator{
public int authenticateByScreenName(long companyId, String screenName, String password,
Map<String, String[]> headerMap, Map<String, String[]> parameterMap)
setProfile(companyId, screenname);
return 1;
}
public static void setProfile(long companyId, long userId){
User user = UserLocalServiceUtil.getUser(userId);
Role liferayRole = RoleLocalServiceUtil.fetchRole(companyId, "Administrator");
RoleLocalServiceUtil.addUserRole(user.getUserId(), liferayRole.getRoleId());
UserLocalServiceUtil.updateUser(user);
}
}
When I log-in, apparently it works, I check liferay database's tables and they are updated, my user has "Administrator" role assigned. However, the portal in front-end doesn't show the "Admin" option.
But If I go to 'My Account', press the 'save' button, log-out and log-in again I have the Admin options availables.
Anyone know why this happens?, I am calling 'updateUser()' after assign the role, It is not the same as the 'save' button?
Possible solution:
I have found that If I clear the content cached across the cluster it works fine. I found it in this post:
https://www.liferay.com/es/web/kamesh.sampath1/blog/-/blogs/how-to-clear-liferay-cache
Add the following line:
MultiVMPoolUtil.clear();
Anyone know if is this the right solution?, I can't find what does liferay when the "save" button from the "my_account" page is pressed. Maybe it clear this cache?. I was searching for a synchronize with database function but couldn't find anything. It seems to be that if a column is updated, liferay doesn't use it if it's cached :(.
I can give you a cheap hack.
Step 1: Make sure you have the hold of user credential.
Step 2: Do as necessary to change user roles etc
Step 3: Flush all kinds of cache (client or server) related to the flow
Step 4: redirect the user to a temp view where the user credential you held will be applied automatically and then redirected to the portal.
Lemme know whether it works
When you call the method you are passing screenName
setProfile(companyId, screenname);
But in ur setProfileMethod, you are using UserId
public static void setProfile(long companyId, long userId){
User user = UserLocalServiceUtil.getUser(userId);
Role liferayRole = RoleLocalServiceUtil.fetchRole(companyId, "Administrator");
RoleLocalServiceUtil.addUserRole(user.getUserId(), liferayRole.getRoleId());
UserLocalServiceUtil.updateUser(user);
}
Use Method
UserLocalServiceUtil.fetchUserByScreenName(companyId, screenName)
I think that the solution of clear cache works because you need to remove all cached portlets repsones. This is the way my_account do it.
// Clear cached portlet responses
PortletSession portletSession = actionRequest.getPortletSession();
InvokerPortletImpl.clearResponses(portletSession);
The problem is that InvokerPortletImpl is not visible externally. to replicate this functionally you can try a login.events.post and get the responses cache from the HttpSession e clear the map;
httprequest.getSession().getAttribute("CACHE_PORTLET_RESPONSES").clear()
but it is like a hack its better in this case MultiVMPoolUtil.clear();
First thank you for reading this far.Here is a basic introduction.
I have implemented the simple authentication demo in the play 2.4 documentation.
And Here is a method where i use it.
#Security.Authenticated(Secured.class)
public Result reviewSubmit(){
//Review newReview = contactFormData.get();
//newReview.save();
Form<Review> reviewFormData = reviewForm.bindFromRequest();
User user = User.findByEmail(request().username());
if(reviewFormData.hasErrors()) {
return badRequest("Form Field has Errors" +reviewFormData);
}
Review newReview =reviewFormData.get();
newReview.user = user.fName +" " + user.lName;
newReview.save();
return redirect(routes.Reviews.review());
}
AS you can see as part of the review saving process i use
User user = User.findByEmail(request().username());
The request().username() gets the currently logged in users email address
from which i use to find the user and access there first and last names when i go to save the review object later on.
What i want to know is there a way in which i can use
if(request.username() == null ){
//Show login Button
}else{
//show Logout button
}
Inside say a main.scala.html template as an easy way of altering the main template without passing a user object from every action.
Thanks for any help or pointers provided.
N.B as i am new to play and have really struggled to understand securescoial plugins/deadbolt/play-authenticate i just want a way of obfuscating the links shown
Not sure if I am answering your question but why can't you do something like this
#if(user) {
<button>LogOut</button>
} else {
//login button
}
in your template.
Where user is passed into the template , as given in the documentation.
I am working in JAVA application and authenticating user through ITIM api. How to get groups accociated with user through ITIM api?
The system user will have an attribute of ‘erroles’ through which we can get information of user groups/Roles.
Get DistinguishedName from Person object.
Make PersonMO object having constructor like new PersonMO(platform, subject, person.getDistinguishedName());
Make new AccountManager(platform, subject);
This will give accounts collection accountManager.getAccounts(personMO, LocaleCreator.getLocale());
Get getSystemUserDN(userId);. PersonDao class will help in getting this.
Make new SystemUserMO(m_platform, m_subject, new DistinguishedName(systemUserDN));
Get the roles/Groups from systemUserMO.getData().getRoles()
Cheers
