I have three accounts in my application, this definitely means I have three guards. In my controller when I do this :
dd($apartment->user_id = Auth::id());
I get the users user_id from the users table. I would like to get the user_id from the agents table whose guard I have named agent. I try this :
dd($apartment->user_id = Auth::agent()->id);
and I get this error :
Call to undefined method Illuminate\Auth\SessionGuard::agent().
Does anyone know how I can correctly point to my desired guard?
This is how you get user_id of a specific guard : Auth::guard('name_of_your_guard')->id();

I've got the problem when two people at the same time tries to add each other to friends. So, at first when one person presses add to friends he checks, whether other user's groups doesn't have my ID. If he has, I don't need to create new group - I will just add this group's ID to my list, else - I will create new group. Now, when two people at the same time press that button, they both get the result that group doesn't exist thus they both create a new group. How to solve these kind of problems?
Structure:
"userGroups" : {
"myId1" : {
"generatedGroupId1" : "myFriendID1"
}
}
Update: I've managed to do it: basically in doTransaction I create group if it doesn't exist and then on onComplete I work with already created group. If two people start creating new group, one end up creating it, second one - reading it.
// function
ref.runTransaction(object : Transaction.Handler {
override fun doTransaction(currentData: MutableData): Transaction.Result {
// create group here if data is null
return Transaction.success(currentData)
}
override fun onComplete(
error: DatabaseError?,
committed: Boolean,
currentData: DataSnapshot?
) {
Log.d(TAG, "postTransaction:onComplete:" + error)
// continue doing stuff, group already exists at this point
}
})
}
It's hard to give specific without seeing your code, but the most likely options are (in order of my personal preference):
Base the group ID on the two users in it. If you do this correct, the two users will end up with the same group ID, and it doesn't matter who is first. Creating the groups then becomes a so-called idempotent operation, which means that if you run the same operation multiple times, it will have the same result. For an example of such group IDs, see Best way to manage Chat channels in Firebase
Use a transaction to ensure only one write makes it through. This would mean that the second user ends up reading the group created by the first user, and can then cancel their data creation.
Use a Cloud Function, which can perform more (non-atomic) read operations to check whether the group of users already exists, and reject the request from the second user.
The Agora.io doc is specifing for the joinChannel method :
The user ID. A 32-bit unsigned integer with a value ranging from 1 to
(2^32 -1). This parameter must be unique. If uid is not assigned (or set
as 0), the SDK assigns a uid and reports it in the joinChannelSuccess
callback. The app must maintain this user ID.
I have 2 use cases :
For the users registered to my app : i want the app to assign an uid
For the users not registered to my app : I want to let agora.io decide of the uid
The issue is that doing so, I may get into collisions between userIds assigned by the app and usersIds assigned by agora lib.
But if you are assigning uids within a range of values (other than 1 -> 2^32) then i could rely on that.
Is it the case ?
thx.
in this case, i think you can use the string user name to join the channel. You can take a look at this doc: https://docs.agora.io/en/faq/string
I am using simple membership provider and mvc. After a user registers he/she will be redirected to a view called registerDepartments. Incase time is an issue the user can login at a later stage. How do I retrieve the data registered by the user previously. In my previous workings it shows all the data from the table for all users who registered a branch.
I didn't get your question clearly, because you didn't show any code of your work and any example.
However I think you want to retrieve branches created by a user for him/her right? If So, you can use something like the following:
var currentUserId = (int)Membership.GetUser().ProviderUserKey;
var branches = dbCtx.Branches
.Where(b => b.CreatorUserId == currentUserId).ToList();
I have a question about the rbac system. I think I've pretty well understood it but I need more informations about a special case.
I would like to do the autorisations on groups instead of users. I mean for instance the group "HR" has permission to create a person. Then any person who join this group would have it as well.
Let me give you more informations.
A part of my database:
And this a part of what my group hierarchy could be:
So what I'm looking for, this would be a must, is a system where each group has some autorizations. People get the autorizations of their group and of their parents group (for instance people in "Forsys" has the autorizations of "Forsys", "R&D" and "Administration").
The solution I see at the moment is using bizrule. But I'm not sure write php code in database is a good idea and then if I update the group hierarchy (R&D inherits of RH instead of Administration) I would have to modify bizrule in database. I tried it and it works well but as you can see it require a lot of code.
$user = User::model()->with("people","people.groups")->findByPk(Yii::app()->user->id);
foreach($user->people[0]->groups as $group)
if($group->id == 2)
return true;
return false;
It's just for see if a user is in a group (without checking parent groups and hierarchy)
Another possibility could be create a new table "group_auth" where we would say for instance:
-Group_2 has role "managePerson"
-Group_3 has operation "deleteUser"
...
And then everytime a user is added in or removed of a group we would update his autorizations in the auth_assigment table.
I'd like to hear other opinions on this subject.
All comments will be appreciated :)
Thank you for reading and sorry for my English if you had difficulties to understand me.

Do users ever get their own authorization items? If not, seems like you could in essence swap out the userid column in auth_assignment and name it / treat it as groupID instead. That way you wouldn't need to worry about keeping user auth assignments in sync with your group roles.
A couple of places you'd probably need to make some changes:
- by default CWebUser passes in the logged in userid for use in bizrules. Might be good to change that our with your own override that passes in groupId/groupIds instead.
- you'd need to override CDbAuthManager and rework some of how things work there
We've done something similar on a project I've worked on (we were handling multi-tenant RBAC custom permissions), which required custom CDbAuthManager overrides. It gets a bit tricky if you do it, but there is an awful lot of power available to you.
Edit:
Understood about your users sometimes needing to have additional authorizations. What if your group has a 'roles' field with different roles serialized in it (or some other method of having multiple roles stored for that group, could also be a relationship).
Then, on user login (for efficiency), you'd store those roles in session. Probably the easiest way to handle things would be to write a custom checkAccess for your WebUser override:
https://github.com/yiisoft/yii/blob/1.1.13/framework/web/auth/CWebUser.php#L801
as that will make things simpler to do your custom checking. Then I'd probably do something like:
if(Yii::app()->user->hasGroupAccess() || Yii::app()->user->checkAccess('operation/task/role')) {
....
}
In your WebUser hasGroupAccess method, you could loop over all group roles and send those to checkAccess as well.
Think that will work?
What I use to check access for groups when it's in another table, or somewhere else in the application I give the user the role per default. By using this:
return array(
'components'=>array(
'authManager'=>array(
'class'=>'CDbAuthManager',
'defaultRoles'=>array('authenticated', 'R&D', 'Administration'),
),
),
);
Under: Using Default Roles
By using this, every user gets these assignments. Now, I create a business rule to make sure that the checkAccess('group') will return the correct value.
For example in your case the business rule for R&D would be:
return (
count(
Person::model()->findByPk(Yii::app()->user->id)->groups(array('name'=>'R&D'))
) > 0
) ? true : false;
So what this does is:
find the logged-in person by primary key
look into groups (from the user) for the group with name R&D
if there is a group: return true (else return false)
My Object has many transactions which belong to a type, whcich then belong to a group. I would like to pull all the transactions from my Object which are in a specific group, say blue.
Been trying to do this using both SQL and Activerecord and have failed in both endeavors.
I can get this procedure to print out the quality by which I then want to sort by:
object.transactions.map { |to| "#{to.transaction_type.transaction_group.name}" }
And here is a sample of what i have been running, but oviously dosen't work. Haven't managed to find a way to
id = Group.find_by_name("name")
object.transactions.where(transaction_type.group_id == id)
Can you do something like:
id = Group.find_by_name("name")
object.transactions.
joins(:type).
where("types.group_id" => id)
