Easy Admin panel with Rails - database

I have created a web page with RoR and i am using auth system that i wrote. Now i would like to create an admin panel, where i can see the user info etc..
I am not sure but what i though is to add a column name to auth system like admin? giving a default name false. Then if the admin? is true admin panel opens instead of the web page login.
I wonder if i can use the same auth system so in order to login to page it logs in to admin panel.
But in the controller it will check if admin? is true for every user, i am not sure about the burden in terms of the system requirments as it will check every user.
And i know there are other gems for admin panel but its fine i can design it. I am just not sure which way is the efficient way.

The burden on the system will be negligible. It depends a little bit upon how your auth system is configured, but I am assuming that you give the user a token when he/she is properly logged in.
When the user first tries to sign in, you should check if they are an admin. At this point, if they are, then you can sign them in as an admin, also storing that information in the session. You should perform this check on the controller actions where they need to be an admin. It will not affect performance to any noticeable degree and is important for the security of your site.
Also, you may want to check out the CanCanCan gem, which is a fork of CanCan built by Ryan Bates, for an example of how this works. Unless you're building the application for educational purposes, I highly recommend the CanCanCan gem.
Hope this helps!

In addition to that, you may try Rails_Admin, which provides an easy-to-use interface for managing your data.
And I've considered to use this gem for my project, which is a huge database, so it seems to very helpful.

Best practices for similar RBAC schemas?

I all, I'm writing a boilerplate for future projects. Composition is as follows:
Server:
Express,
Prisma 2,
Typescript,
JWT Auth (Access token in memory, Refresh in cookie)
MySQL
I'm writing an RBAC schema, and have successfully written express middlewares to determine if a user is logged in, and for if a user has a specific permission on their role.
If you've ever used any of the minecraft server permission plugins, I'm trying to emulate the common pattern used there.
Users have role(s)
Roles have permissions
Roles can inherit permissions from one or more roles
Roles have a "nextRole" field to determine what role to give when the "promote" event is triggered.
Everything works fine on the server side.
What I'm wondering about is, how should I go about copying the middlewares (login, permissions) to the client side, and how should I determine whether a user has permission to do something?
What I've looked at:
Creating a "hasPermission" endpoint wouldn't be very good as I'd need to make an API call every time a permission check is needed.
Eager loading all roles and permissions from the api when logging in and returning them in the response (I can't eager load the recursive role inheritance/nextRole as far as I know)
Returning ONLY the user without roles and permissions for the JWT/login bit and getting roles/permissions from their own endpoints (again, needs to be recursive to get all inheritance and said permissions from inheritance)
Has anyone created an RBAC schema like this, and how did you go about checking permissions on the client side without being too redundant/using too much memory/too many api calls?
This is a good question, here's my answer to it.
An app is normally protected by the auth info, which means it could be blocked if a user is not permitted. If this is a server application, it can be easily done, because the session can be used to find out the current user info including roles.
However if this is a client app, it's a bit tricky. Say we can protect a route (page or section of page) once the user log in.
if (!user.authenticated) return null
We can use the above line to block private or public user. Or other information you can grab from the user to protect more.
if (user.role !== 'Admin') return null
We could wrap in these into a component, such as
<Allow role="admin" render={...} />
I believe you get the point. However there's something which is very unique about the client approach. The entire user info is returned back, and only the user info, not the user type or permission type.
So to follow your plan, do we need to share a permission or role type to the client side? This is a million dollar question.
In practice, the UI never needs the complete info, why? because UI normally reshapes the permission a bit. That doesn't mean you can't share the complete info from the backend. Doing that may make the UI job easy or more complicated. Nobody knows.
The reason is what I explained above, the UI is writing a if statement (could be hidden) anyway. Either this if is true or false, most of the front-end code is already loaded. It's very different than the backend version, which can entirely block the deliver of the content.

How to have a safe admin handling with reactjs and firebase

I would like to add functionalities depending on whether or not the user logged in is the administrator but I don't really know which condition (for conditional rendering with delete buttons etc) I should use to check if the user is the admin or not. Is it safe to do it based on the id of the user ? In the first place, I thought about testing the user in every component I want him to have functionalities, with a state called "user" using recoiljs to get access to the user in the whole app but I'm afraid people could change the state with the react tool extension and then pretend they are the admin and so delete articles and stuff... What's the best way to test if a user is the admin or not using firebase authentification in a react project ?
It's never safe for client code to assume admin responsibilities without absolute enforcement from your backend. It's unsafe because client code can be compromised and might not work the way you expect. And it's running on a device that the user controls fully.
Client code can check some indicator to see if the user is admin (in whatever way you find suitable), but the final check needs to happen on your backend, either through security rules (if you're using Firebase products like Realtime Database, Firestore, or Cloud Storage), or in code running on a secure backend, including products like Cloud Functions.

Salesforce: How to automate report extraction as JSON/CSV

I am new to Salesforce, but am an experienced developer. I am provided a link to a Salesforce report, which mostly has the right filters (query). I would like to use an REST API to pull that information as CSV or JSON so that I can do further processing on it.
Here are my questions:
Do I need special permissions to make API calls? What are they?
Do I need to create an "app" with client-key & secret? Does my admin need to grant me permission for this too?
There are a lot of REST APIs from Salesforce, which one do I need to get the info from the report? Analytics?
How do I authenticate in code?
You'd have to work with the System Administrator on the security pieces. Anybody who knows how the company works, can all users see everything, is there Single Sign-On in place, how likely is the report to change...
You will need an user account to pull the data. You need to decide if it'll be some "system account" (you know username and password and have them stored in your app) or can it run for any user in this org. It might not matter much but reports are "fun". If there will be data visibility issues 6 months from now, you'll be asked to make sure the report shows only French data to French users etc... you can make it in report filters or have multiple reports - or you can just use current users access and then it's the sysadmin that has to set the sharing rules right. (would you ever think about packaging what you did and reusing in another SF instance? Making a mobile app out of it? Things like that, they may sound stupid now but will help you decide on best path)
The user (whether it'll be system account or human) needs Profile permissions like "API Enabled" + whatever else you'd need normally ("Run Reports" etc). If you're leaning towards doing it with system user - you might want to look at Password Policies and maybe set password to Never Expires. Now this is bit dangerous so there would be other things you might want to read up about: "API only user" (can't login to website), maybe even locking down the account so it can login only from certain IP ranges or at certain times when the job's supposed to be scheduled...
Connected App and OAUth2 stuff - it's a good idea to create one, yes. Technically you don't have to, you could use SOAP API to call login, get session id... But it's bit weak, OAuth2 would give you more control over security. If you have sandboxes - there's little-known trick. You can make connected app in production (or even totally unrelated Developer Edition) and use client id & secret from it to login to sandboxes. If you create app in sandbox and you refresh it - keys stop working.
(back to security piece - in connected app you can let any user allow/deny access or sysadmin would allow only say these 3 users to connect, "pre-authorize". Could be handy)
Login - there are few REST API ways to login. Depends on your decision. if you have 1 dedicated user you'll probably go with "web server flow". I've added example https://stackoverflow.com/a/56034159/313628 if you don't have a ready SF connection library in your programming language.
If you'll let users login with their own credentials there will be typical OAuth "dance" of going to the target page (Google login, LinkedIn, Twitter...) and back to your app on success. This even works if client has Single Sign-On enabled. Or you could let people type in their username and pass into your app but that's not a great solution.
Pull the actual report already
Once you have session id. Official way would be to use Reporting API, for example https://developer.salesforce.com/docs/atlas.en-us.api_analytics.meta/api_analytics/sforce_analytics_rest_api_get_reportdata.htm
A quick & dirty and officially not supported thing is to mimic what happens when user clicks the report export in UI. Craft a GET request with right cookie and you're golden. See https://stackoverflow.com/a/57745683/313628. No idea if this will work if you went with dedicated account and "API access only" permission.

apex how to login to another application from link in one application?

I have two applications in my workspace, APP 1 and APP 2.
In my case, user will log in to APP 1. from there, i put a menu(or a link) to APP 2. however APP 2 requires authentication. So it will take me to a login page. i would like to eliminate that and get the current user's credentials on APP 1 and login to APP 2.
i'm looking for a simple straightforward method (but need to consider security) to login to APP 2.
what i could think of is apex_collection..i could store credentials n use it to create a login process for APP 2. however apex_collection is session based. eventhough i've set session for APP 2, it still wont read values from my apex_collection.
Does anyone have a suggestion or a solution?
All you need to do is use the same authentication scheme in both applications and set the cookie name attribute to the same value in both authentication schemes like this:
APEX will then use the same session across the two applications and the user will not have to log in again when they navigate from one to the other, provided of course that you pass the SESSION_ID in the URL.
A Few Comments on Default APEX Workspace Authentication Security
It may also be helpful to expand on an explanation of why the solution posted by #TonyAndrews works.
For any Apex Apps within the same workspace, if they use the default "APEX Application Authentication" method, they will consult the same authentication user list... so USER1 and its password is a valid login for any of the "neighboring" applications...
This may be a concern if you are hosting different clients or users that should not be intermingling with the other applications. You can also define user GROUPS in the same place as you set up each workspace user. Each application can have its own security filter that permits access by membership of BOTH user/password authentication AND membership in the appropriate access group.
Sharing workspaces may also be a problem because of the unique user name restriction of a single workspace. You can get around that by:
Defining different name-spaces for each application:
Email addresses are good: "someuser#sampledomain.com"
An app id prefix such as: SHOP_EDNA, SHOP_GARRETT, TC_KAREN, TC_MARLOWE, MY_BORIS etc.
Different name styles: first name only, first name + last initial, etc.
To keep things simple, you can always just spin up a brand new workspace: a warning however is that common user names like `ADMIN` are NOT the same between separate workspaces. There shouldn't be much concern however because apps or workspace users may have the same or different schema access privileges to the database back end.
A Word of Caution to Administrators and Developers:
When you go live with an application or multiple applications on a user-facing system, keep in mind the deployment destination (i.e., the workspace) and what else is sharing that workspace. There are some real situations where apps are not intended to be shared or accessed by other "inside" users. Be sure to read up and understand the security constraints and methods of using Default Apex Authentication security so that it's more than luck that protects your own production/live deployed applications.
I do have the similar requirement, linking from one application page to another.
Tried the above mentioned solution, but still asking to login to second application. My Apex ver is 5.0.3 and trying in same workspace.
Created new authentication schemes for each app with same cookie name and set them as current authentication. Scheme type are Application express accounts.
Setting the link as below from first app page to second.
href="http://servername:port/apex/f?p=224:2:&APP_SESSION"
Could anyone provide a solution, please?
Just an update on this.
I am currently using v21.2 and this is how I do it:
In both applications, go to Shared Components > Authentication Schemes > (Select your Auth Scheme);
Scroll down to Session Sharing and select 'Workspace Sharing';
In one of the applications (source), create a link (as a Navigation Bar List entry, for example) like f?p=173:1:&SESSION., where 173 is the target application ID and 1 is the target page.
After some research, I've found out that this feature (Session Sharing Type) is available since v18 of APEX.

Creating a login like Basecamp in CakePHP

I am trying to create a basecamp like login where users can login to see their companies projects using the url:
http://abc.com/companyname/
I dont know how to create a 2 level auth... (one at the company level and another at the user level)
I am new to cakePHP and I dont know how to modify the in built Auth component for my requirement.. Any help would be grateful...
I would use the Auth component for the login. I wouldn't mess with the ACL and stuff as that's pretty confusing I find.
I would approach this by adding a user_level, access_level, or permissions column in your users table. Then in here you can store a numerical value or similar.
Then in the User model, when they login using Auth you can store that value in the Auth user session object. So you can get at it using $this->Auth('User.access_level') in your controllers.
Now the Auth component by default has an isAuthorized() function in the app_controller. This function is called to see if someone has logged in. You can modify this to check that access_level and take action appropriately. I used this technique so that users can't get into the /cms routing unless they are admin = 1.
There is more information on this in the docs, http://book.cakephp.org/view/172/Authentication and you can find out more about isAuthorized() here, http://api.cakephp.org/class/auth-component#method-AuthComponentisAuthorized
Do make sure that you setup all your Auth component variables in your app_controller. Also make sure that your auth type is set to controller, and that you're allow() and deny() are configured properly.
The one big catch with all this, is that if you using a beforeFilter() in your controllers, you will need to make sure to do parent::beforeFilter() to ensure that the stuff in the app_controller is run beforehand :)
Honestly, I think that you should check out the ACL component. The book tutorial is very good if you follow it through. The major caveat is that it does not provide a mechanism for row-level access control (e.g. can user X edit this particular entry). However, it does provide a basis for doing user/group level access control, which you can then extend yourself to create the row level access you require.
In short, the ACL component supports cascading permissions (e.g. subgroups can have finely-grained access control, but otherwise inherit permissions from the parent group). That can make life a lot easier, if you need both robustness as well as granularity.
You might also check out the bakery, as there are additional auth components written by the community that may serve what you need. Highly recommended, as Auth/ACL stuff is difficult to do well, and always a major concern with web apps.
