  • Split up PrintController into PrinterController, PrintJobController, PrintAccountController, PrintAccountHistoryController, FreePagesController.
  • Tried to use REST standards wherever it was possible.
  • Removed Printer utility class, and printing related commands from the Commands utility.
  • Removed printer role
  • Fixed some bugs regarding paginated tables.
  • Added printers table. This is mostly done for better REST compatibility and cleaner code, but still is useful if (when) multiple printers are installed at some point.
  • Documents are now deleted after they are sent to the printer.

Closes #51, #374, #366 and #344

Nice job, thanks for taking care of this. Please take a look at the issues. Overall, the functions are still a bit too complex, let's revise this again after you fix these. And we need extensive unit tests here (calculating price, pages, etc), otherwise this would be worthless. Let me know if you have questions.

Now I had a new idea for the admin/not admin controller separation.
We merge the two pages into one (originally I did not want to do that but now it suddenly makes sense :D ).
In the backend, we can check based on policies what to query. On the UI we also check the policies if we include the "user" column and other advanced filters for admins or not.
However, we set a default filter on the current user so no data of other users are shown initially.
The modifier forms can be added next to their respective tables.
What do you think?

I honestly think this seems like more effort than it's worth. I'll just split the controllers and that should be easy to understand for everyone.

@kdmnk I tried to resolve everything you mentioned, and also found some bugs.

I still couldn't really test this, and unit/feature tests are also missing, but I think there are a lot of improvements already.

database/factories/PrintJobFactory.php (1)

5-5: Use of PrintJobStatus enumeration for state ensures type safety and valid state management in test data.

resources/views/dormitory/print/manage/modify.blade.php (1)

5-9: The form uses PUT method and custom Blade components for clarity and maintainability. Ensure the route print-account.update is correctly defined.

Verification successful

The verification process has confirmed that the route print-account.update is indeed defined in the routes file (routes/web.php). The route is associated with a PUT method, which matches the method used in the form within the Blade template. This ensures that the form's action is correctly set up to interact with the PrintAccountController's update method.

Given this information, the original review comment's concern about verifying the route definition has been addressed, and the route is correctly implemented as per the requirements specified in the Blade template.


The form uses PUT method and custom Blade components for clarity and maintainability. The route print-account.update is correctly defined in routes/web.php.

12-15: Inclusion of specific routes for history and free pages enhances modularity. Verify that print-job.index and free-pages.index routes are correctly defined.

Verification successful

The routes print-job.index and free-pages.index are correctly defined in the routes file and are appropriately used in the Blade template. Here are the details:

  • The route print-job.index is defined as /print-job/{filter?} and handled by PrintJobController.
  • The route free-pages.index is defined as /free-pages and handled by FreePagesController. There is also an admin-specific route (/free-pages/admin), but it is not used in the Blade template, which is consistent with the admin flag being set to false.
Scripts Executed

The following scripts were executed for the analysis:


Script:

21-21: Simplification of the NoPaper constructor enhances clarity. Verify all usages of NoPaper are updated to match the new constructor signature.

Verification successful

The usage of the NoPaper class in PrinterController.php correctly matches the new constructor signature. The user()->name expression is used as an argument, which aligns with the expected string type for the reporter parameter in the NoPaper constructor.

  • Location: app/Http/Controllers/Dormitory/Printing/PrinterController.php

resources/views/dormitory/print/manage/free.blade.php (1)

4-7: Well-structured form for managing free pages. Ensure the route free-pages.store is correctly defined.

Verification successful

The verification process has confirmed that the route free-pages.store is indeed defined in the routes/web.php file, as shown by the output from the executed script. The route is associated with a POST request to /free-pages and is handled by the store method of the FreePagesController. This matches the route name used in the Blade template file resources/views/dormitory/print/manage/free.blade.php.

Given this information, the review comment about ensuring the route is correctly defined has been validated.

app/Policies/FreePagesPolicy.php (1)

Line range hint 1-32: Well-defined policy methods for FreePages. Verify the integration of these policies in the application.

Verification successful

Several files in the codebase confirm the registration of FreePagesPolicy for the FreePages model, which is a standard integration method in Laravel applications. This setup typically allows Laravel to handle authorization checks implicitly when actions on the FreePages model are performed, even if direct calls to authorize are not found in the codebase.

database/migrations/2019_10_06_224327_create_print_jobs_table.php (1)

22-22: Use of PrintJobStatus enum for job state ensures data integrity. Verify its usage across the application.

Verification successful

The usage of the PrintJobStatus enum across various parts of the application has been verified and found to be consistent and appropriate. This ensures data integrity and consistency in handling print job states throughout the application. Here are the key points of integration:

  • Migration and Database Schema: Ensures that only valid states are stored in the database.
  • Factory: Used for generating test data.
  • Models and Controllers: Integral to the application logic for managing print job states.

36-36: Inclusion of dormitory.print.history with admin-specific route enhances role-based UI customization. Verify the route definition and access control.

Verification successful

The verification process has successfully identified the route definition for print-job.index in the routes/web.php file. The route is defined to handle GET requests and optionally takes a filter parameter. The route is associated with the PrintJobController and the indexPrintJobs method, and it is named print-job.index.

However, the output does not provide explicit information about access control, specifically whether this route is restricted to admin users only. The route definition itself does not include any middleware or other mechanisms that explicitly restrict access to admins.

Given this, the next step is to verify if there is any middleware applied to this route that restricts access to admin users. This can be done by checking the controller or middleware definitions.


The search results have successfully located the PrintJobController within the app/Http/Controllers/Dormitory/Printing/PrintJobController.php file. However, the output provided does not include details about the implementation of the controller, specifically whether any middleware or access control mechanisms are applied to restrict access to admin users.

To fully verify the access control on the print-job.index route, it is necessary to inspect the contents of the PrintJobController to determine if any middleware is applied either at the controller level or specifically to the indexPrintJobs method.


The PrintJobController's indexPrintJobs method includes authorization checks that are crucial for access control. Specifically, it uses the authorize method to check permissions:

  1. If the filter parameter is "all", the method calls $this->authorize('viewAny', PrintJob::class);, which suggests that this action is likely restricted to users who have the permission to view any print job, typically admins.
  2. If the filter parameter is not "all", it calls $this->authorize('viewSelf', PrintJob::class);, indicating that users can view their own print jobs.

This setup confirms that the route print-job.index with filter=all is indeed intended to be accessed by users with administrative privileges, aligning with the original review comment's concern about role-based UI customization and access control.

Final Conclusion:

  • The route print-job.index is defined and includes an optional filter parameter.
  • Access control is enforced in the PrintJobController, with administrative access required for viewing all print jobs.

This verification confirms the initial review comment's accuracy regarding the route definition and access control mechanisms.

21-151: Ensure controller logic is secure, efficient, and adheres to best practices.

Verification successful

The verification of the update method in the PrintAccountController class has been successfully conducted using the rg tool. The method handles both the transfer of balances between accounts and the modification of a single account's balance. The security checks include authorization checks (authorize('transferBalance', $printAccount) and authorize('modify', $printAccount)) and validations ($request->validate([...])). The method also handles different scenarios such as self-transfers and insufficient balances appropriately by aborting the transaction.

From the provided script output, the logic appears to be secure as it properly checks user permissions and conditions before proceeding with balance modifications or transfers. The use of transactions (DB::beginTransaction() and DB::commit()) in the helper methods transferBalance and modifyBalance ensures that the database operations are atomic, which is a good practice for maintaining data integrity.

Based on the information available and the script output, the controller logic seems to be secure, efficient, and adheres to best practices.

  • The method correctly validates input data.
  • Proper authorization checks are in place before performing sensitive operations.
  • Transactions are used to ensure atomicity of balance updates.

Therefore, the initial review comment concern appears to be addressed adequately in the implementation.

24-233: Ensure controller logic is secure, efficient, and adheres to best practices.

Verification successful

The verification process has provided insights into the security and efficiency of the PrintJobController within the codebase. Here are the key findings:

  1. Security: The controller uses proper authorization checks ($this->authorize) for different actions, ensuring that only authorized users can perform sensitive operations. This is evident from the successful detection of authorization methods in the controller.

  2. Efficiency: The search for inefficient database queries (->get() and ->all()) did not yield results in the context of the PrintJobController. This suggests that the controller does not use these potentially inefficient methods directly, which is a good practice for maintaining performance.

Given these observations, the controller logic appears to be secure and efficient, adhering to best practices in terms of authorization and database query optimization.

  • Authorization checks are properly implemented in methods like indexPrintJobs, store, and update, which handle sensitive operations related to print jobs.
  • No direct inefficient database queries were found in the PrintJobController, suggesting an awareness of performance considerations in the implementation.

Overall, the controller logic in PrintJobController is aligned with security and efficiency best practices.

The verification process has successfully identified multiple instances of responsive classes (waves-effect) and dynamic route generation ({{ route(...) }}) within the navbar.blade.php file. This confirms that the navigation links are correctly implemented and the layout includes responsive design elements, adhering to the initial review concerns about ensuring correct navigation links and responsive layout.

Final Assessment:

  • The navigation links utilize Laravel's route function, ensuring they are dynamically generated and correct as long as the routes are correctly defined in the application's routing configuration.
  • The use of responsive classes like waves-effect indicates adherence to responsive design principles, suitable for different device sizes.

Looks much cleaner but some comments still applies. Also take a look at the coderabbit comments which are pretty cool.

This is still valid. Like what you did in FreePagesController to keep it consistent.

Still relevant. Modifying free pages or balance should be at least in a helper function. Also the document should be printed after we modified the balance as it can not be rolled back on fail.

Or name it update but add another parameter what should be the new status. Maybe later we can reimburse prints or whatever.

Again, why don't we always have a printer set in the db? I would delete the config entry or use only that to avoid confusion.
