Make some small changes and aditions in a Laravel 5.2 project

1. Make middleware: If a user logs in and there is no company associated with the user (field active_company is not set or the company with that id is deleted), force the user to create a company first before allowing any other route. (there is already a blade and controller for creating company), just refer there with a message "You need to create a company first". 2. Enable adding, editing and deleting of contact groups via ajax in the new/edit contact screen. Some of the UI is there already, it's just a select with a buttons next to it for edit/new, they should show a bootstrap popup. After submitting the edit/add (when the ajax call is successfully completed) it should update the select field on that page on the fly and select the newly made group. 3. Use ag-Grid with editor enabled to enable multiple barcodes per product. 1 product has many barcodes. each barcode has a quantity (default 1). Add/edit/delete should all be handled from the ag-Grid. Ag-grid has event for "on finished editing" that you use to fire an ajax call. (working laravel example available, also check ag-grid documentation for more info). As in the example that i will provide I like the data to be lazy loaded form the sever and use server sided filtering. The only thing not included in the example that i will provide is adding a new row. The ag-grid provides this trough their grid API, you may just add a button "add barcode" below the grid that adds a blank row that the user can edit. 4. Make a "query scope" to compare the company_id that returns from the database with the user()->active_company on each database request. (on each get and delete) [access()->user()->active_company == $collection->company_id], if not, return 403. Right now we have two controllers that need those checks, but it will be (re)used throughout the app for almost every database related action. GitHub access available on request. Project is based on rappasoft laravel-5-boilerplate.
