This document provides a detailed overview of the user interface components in the osysHome-Users system. It focuses on the template structure, layout patterns, and interactive elements that constitute the user management interface. For information about the data structures and forms that populate these templates, see User Data Models and Forms.

Template Organization

The osysHome-Users plugin utilizes a layered template architecture with a consistent layout inheritance pattern. All UI components extend a common administrative layout to maintain visual consistency throughout the user management interface.

Common Template Features

Each template in the user management system shares several common elements that create a unified user experience:

  1. Breadcrumb Navigation: Provides hierarchical context and navigation
  2. Form Error Handling: Consistent display of validation errors
  3. Action Buttons: Standardized button styling and positioning
  4. Responsive Layout: Bootstrap-based grid system for device adaptability

User List Interface

The user list interface provides a tabular view of all users in the system with options to add, edit, delete users, and manage their passwords.

Key Components

Component Description Source Location
Add User Button Creates a new user templates/users.html:6
User Table Displays user information in columns templates/users.html:7-35
Action Buttons Edit, Password, Delete operations templates/users.html:28-30
Avatar Thumbnails Small user profile images templates/users.html:21-22

The interface displays the following user information:

  • Username with avatar
  • Role
  • Home page
  • Last login timestamp
  • Action buttons for each user

Avatar Upload Feature

The user profile interface includes an avatar upload functionality implemented through a modal dialog box. When the user clicks the upload button, a modal appears with a file selection field and upload button.

Key components of the avatar upload system:

  • Circular avatar display with upload button overlay
  • Modal dialog for file selection
  • AJAX-based file upload with immediate preview update
  • Fallback to default avatar when image is unavailable

API Key Generation

The user profile includes a feature to generate secure API keys. This functionality is implemented through client-side JavaScript that creates cryptographically random keys when the user clicks the "Generate key" button.

Key aspects of the API key generation:

  • Input field with accompanying button
  • Client-side secure random generation using Web Crypto API
  • Formatted output with hyphens every 4 characters

Password Management Interface

The password management interface provides a simple form for changing user passwords. It includes two password fields (password and confirmation) with validation to ensure they match.

Form Validation Flow

The password form includes validation to ensure password requirements are met. Error messages are displayed at the top of the form when validation fails.

    else Validation succeeds
        Validator-->>Server: Confirm valid
        Server-->>User: Redirect to Users list
    end

Template Rendering and Data Flow

All templates receive data from the plugin controller, which gathers user information from the application's data layer. The forms are populated with this data, and user changes are submitted back to the controller for processing.

Interface Integration with Forms

The UI components are tightly integrated with form objects defined in the forms directory. Each template displays a specific form:

Template Associated Form Purpose
user.html UserForm Edit user profile information
password.html PasswordForm Change user password
users.html N/A (display only) List all users

For detailed information about the form implementations, see User Profile Form and Password Management Form.
