The navigation bar in my application will contain User information (name, profile pic), and some associated data. Since the navigation bar is going to be present in the whole application, I'm putting my logic inside AppController::beforeRender() in order to pass data to the View (in this case, the Element nav_bar).
Is this the right place to implement the logic to retrieve user information and associated data?.
Which of the followings is the correct way to load User model data.
public function beforeRender() {
$this->loadModel('User'); // this one
$this->User->find(...
ClassRegistry::init('User')->find(... // Or this one?
I would save the user information in a Session, otherwise you will be hitting the database in every single request.
So, what you wanna do is: in your login() function you get the user information and save it in a Session. Then, in your element, you simply echo the content you want from your Session.
In your view, Use the AuthComponent class to access to the user information, for example :
to havethe id of user : $use_id = AuthComponent::user('id');
to have all the informations of user : $user = AuthComponent::user();

I am having a problem in ReactJS. I want to create a text editor ( with ReactQuill). So, I want different accounts for each user, such that, if one person creates a note and edits it in his account, the other person should not see this.for example this is my current stage - https://wright-text.web.app. After you create your account and login you would see a note called first note because that's the note I created. What should I do so that when you login you see no notes because you have not created a note, but when I login, I should see the note I had already created. How would I do this ??
You need to add a scope to notes endpoint so that user could only GET notes, which they have created.
You need to add query parameters in the API you are fetching. For example, if you are fetching data via a GET request, add in some specific user id that you assign to your user upon validation and then fetch data of a particular user using that id as a query parameter on your API.
I have a login page,
when a user login for the first time it should show the terms and agreement popup with accept button.
if user is accepted it for the first time . when user login for next time popup should not come.
i want to use local storage for this function no db changes allowed.
so what i have to save in localstorage. the scenario is complex when this has to work for diffrent users.
in angularjs i m using ngstorage plugin.
i can save data into local storage like
$localStorage.data="username";
in this case how i have to save for diffrent diffrent user?
You can have a key value pair, where key indicates the username and value indicate whether it has been loaded or not and push them into an array.
Something like this,
var testObj = { 'John': true };
// Put the object into storage
localStorage.setItem('John', JSON.stringify(testObject));
Similarly for all the users.
Then retrieved by using username,
var retrievedObject = localStorage.getItem('John');
console.log('User has already loaded: ', JSON.parse(John));
DEMO APP USING angular-local-storage
I am using CakePHP 1.3 and a layout which includes a dropdown of organizations a user has access to administer, so I'm trying to populate that dropdown with organizations that contain the userid that is logged in, but I want to populate it before the user sees anything so they can use it in the header. The dropdown needs to appear on every page once logged in. I tried adding the query to pull these organizations in the appcontroller, but userid was not yet available to use in before filter. Where or how should I do this? Should it be in session or is there a better construct to use? Element?
In my app it's no problem to use the user_id from within the beforeRender (if you are using the Auth-Component).
You can use it with $this->Auth->user('id').
I would do it like this: Check in the AppController if the user is logged in. If he is, pull your wanted information from the database (or whereever you get your information from) and store it in a variable called $dropdown for example.
If the user is not logged in, $dropdown will be false.
You now make this variable available to the view with $this->set(compact('dropdown'))
Now in your layout (this is important to you have it on every page) you can easily do a check if $dropdown is false or not. If not, you can work with your variable and show the user your wanted dropdown.
I want to access
id of current logged user
name of current logged user
group_id of current logged user
group_name of current logged user
across the view files, to switch menus and tabs on and off according to group_id.
How can I achieve this with minimum sacrifice of performance?
Thanks
If you use the AuthComponent, it'll store the record of the currently logged-in user in the Session under the key Auth. You can access this anywhere through the session component or helper:
$this->Session->read('Auth.User.name')
Even if you're not using the AuthComponent, the Session is the best place to store information about the current user.
Otherwise and in general, the Configure class is usually a good place to store this kind of global information:
Configure::write('User', array('id' => $id, ...));
Configure::read('User.id');
What I always do is create a AppHelper and create a method for this.
Off course this is similar to deceze's answer but it reduces some code you need to write ;)
function user($key) {
$user = $this->Session->read('Auth.User');
if (isset($user[$key])) {
return $user[$key];
}
return false;
}
Then you can call the id of the user by $this->Html->user('id');
Perhaps you could set the variables you want in your AppController (extended by all sub controllers). You should then be able to access them from all views, though be careful to name them uniquely.

i am planing to set a permission on my event index page, which just allow certain user to view which had set when i add the event. After user click into my event, the event controller will 1st check the user id and check the event database which control the user can see which event in his calendar. The permission is added when user create a event and share to other user. Beside, how can i find the current user id to compare with my event database which is the accurate 1?
any suggestion for me to did this function?
i need to know the code and concept how i get the current user id to compare with all the event database, and allow the current user see the certain event.
thanks alot for your information.
The recommended approach for getting logged in user data is via the AuthComponent itself:
// in any controller
$userId = $this->Auth->user('id');
See Accessing the logged in user in the Auth section of the CakePHP Book.
Use sessions to save and read data for a user between pages.
Within Controllers:
// store a user id in the session
$this->Session->write('User.id', $userId);
// read a user id from the session
$userId = $this->Session->read('User.id');
Within Views:
// read a user id from the session
$userId = $session->read('User.id');
You can use any key you want if you prefer something over "User.id". I simply use this since it is what the AuthComponent defaults to if you are using that.
What you're looking for are ACLs (Access Control Lists). There's an AclComponent built into Cake which you should look into. It works together with the AuthComponent, which will hold the user id. It's a little complicated at first, but worth the hassle.
Also, for a simple approach, have a look at the model and controller settings of AuthComponent::authorize. This allows you to define an isAuthorized() method in your controller or model (your choice) which will store logic that determines access (should return true if access allowed and false if denied).
