基于Google AppMaker的任务分配系统可行性与实现方案问询

Absolutely! Google AppMaker has all the tools you need to build this task assignment system with your specific permission rules. Let’s walk through exactly how to make it work:

First off, yes—AppMaker’s built-in user role management, data security rules, and workflow support are a perfect fit for your requirements. You can easily enforce the hierarchy where HODs approve tasks before managers can access and assign them, plus restrict visibility based on user roles.

2.1 Set Up User Roles #

Start by defining the roles you need in your app:

• Business User: External/internal users who submit tasks
• HOD: Approves tasks and sees all submissions
• Manager: Assigns approved tasks to consultants
• Consultant: Completes assigned tasks

To create these roles:

1. Go to your AppMaker project’s Settings > Users & Roles
2. Click "Add Role" for each of the above, and assign the appropriate users to each role.

2.2 Design the Task Data Model #

Create a Task data model (either using AppMaker’s built-in Cloud SQL or a Google Sheets backend) with these key fields:

• TaskID (auto-generated unique identifier)
• Submitter (reference to AppMaker’s built-in User model, to track who submitted the task)
• TaskDetails (long text field for task description)
• Status (enum field with values: Submitted, Approved by HOD, Assigned, Completed)
• Assignee (reference to User model, nullable until a manager assigns the task)
• SubmissionDate (datetime, auto-set when the task is created)
• ApprovalDate (datetime, nullable until HOD approves)

2.3 Enforce Permission Rules #

This is where you’ll lock down access based on roles. For each role, set custom security rules on the Task model (go to Data > [Task Model] > Security):

For Business Users #

• Create: Allow access (restrict to only business users if needed)
• Read: @datasource.item.Submitter.Email == Session.getActiveUser().getEmail() (only let users see their own submitted tasks)
• Update: @datasource.item.Submitter.Email == Session.getActiveUser().getEmail() && @datasource.item.Status == 'Submitted' (let users edit their tasks only before approval)
• Delete: Same as the update rule (prevent deleting approved tasks)

For HODs #

• Read: Session.getActiveUser().isInRole('HOD') (let HODs see all tasks)
• Update: Session.getActiveUser().isInRole('HOD') && @datasource.item.Status == 'Submitted' (only let HODs update the status to Approved by HOD)
• Create/Delete: Disable these unless you need HODs to create/remove tasks directly

For Managers #

• Read: Session.getActiveUser().isInRole('Manager') && @datasource.item.Status == 'Approved by HOD' (only show tasks that have been approved by HOD)
• Update: Session.getActiveUser().isInRole('Manager') && @datasource.item.Status == 'Approved by HOD' (let managers assign an assignee and set status to Assigned)

For Consultants #

• Read: @datasource.item.Assignee.Email == Session.getActiveUser().getEmail() (only show tasks assigned to them)
• Update: Session.getActiveUser().isInRole('Consultant') && @datasource.item.Status == 'Assigned' (let consultants mark tasks as Completed)

2.4 Build the Workflow UI #

Create dedicated views for each role to streamline the process:

• Task Submission Form: A simple form for business users to fill in TaskDetails and submit (automatically sets Status to Submitted and SubmissionDate to the current time)
• HOD Dashboard: A list of all Submitted tasks, with an "Approve" button. Clicking this button updates the task’s Status to Approved by HOD and sets ApprovalDate to the current datetime.
• Manager Dashboard: A list of Approved by HOD tasks, with a dropdown to select a consultant as the Assignee and an "Assign" button to set the status to Assigned.
• Consultant Dashboard: A list of tasks assigned to them, with a "Mark as Completed" button to update the status.

2.5 Optional (But Useful) Add-Ons #

• Notifications: Use Google Apps Script (integrated with AppMaker) to send email alerts—e.g., notify managers when a task is approved, or notify consultants when a task is assigned. Example snippet for sending an email:

  function sendApprovalNotification(task) {
    MailApp.sendEmail({
      to: "manager@yourcompany.com",
      subject: "New Task Approved for Assignment",
      body: `Task "${task.TaskDetails}" has been approved. Please assign it to a consultant.`
    });
  }
  

• Validation: Add checks to ensure managers can only assign tasks to users in the Consultant role, and HODs can’t approve tasks that are already processed.

All these steps are fully achievable with AppMaker’s visual builder and built-in scripting capabilities. You can iterate on the UI and rules as needed to fit your team’s exact workflow.
