Installation
Add this line to your application's Gemfile:
gem 'lsa_tdx_feedback'
And then execute:
$ bundle install
Configuration
Rails Credentials (Required)
Security Note: All configuration values must be provided by your application. No default values are stored in the gem for security reasons.
Add your TDX API credentials to your Rails credentials:
$ rails credentials:edit
lsa_tdx_feedback:
# Required OAuth Configuration
oauth_url: 'https://your-tdx-instance.com/oauth2' # Note: Do NOT include /token
api_base_url: 'https://your-tdx-instance.com/api'
client_id: your_tdx_client_id
client_secret: your_tdx_client_secret
# Required TDX Configuration
app_id: 123
account_id: 456
service_offering_id: 789
# Required Ticket Configuration
default_type_id: 100
default_form_id: 200
default_classification: '300'
default_status_id: 400
default_priority_id: 500
default_source_id: 600
default_responsible_group_id: 700
default_service_id: 800
Manual Configuration
If you prefer not to use Rails credentials, you can configure the gem manually in an initializer:
# config/initializers/lsa_tdx_feedback.rb
LsaTdxFeedback.configure do |config|
# Required OAuth Configuration
config.oauth_url = ENV['TDX_OAUTH_URL'] # Note: Do NOT include /token
config.api_base_url = ENV['TDX_API_BASE_URL']
config.client_id = ENV['TDX_CLIENT_ID']
config.client_secret = ENV['TDX_CLIENT_SECRET']
# Required TDX Configuration
config.app_id = ENV['TDX_APP_ID'].to_i
config.account_id = ENV['TDX_ACCOUNT_ID'].to_i
config.service_offering_id = ENV['TDX_SERVICE_OFFERING_ID'].to_i
# Required Ticket Configuration
config.default_type_id = ENV['TDX_TYPE_ID'].to_i
config.default_form_id = ENV['TDX_FORM_ID'].to_i
config.default_classification = ENV['TDX_CLASSIFICATION']
config.default_status_id = ENV['TDX_STATUS_ID'].to_i
config.default_priority_id = ENV['TDX_PRIORITY_ID'].to_i
config.default_source_id = ENV['TDX_SOURCE_ID'].to_i
config.default_responsible_group_id = ENV['TDX_RESPONSIBLE_GROUP_ID'].to_i
config.default_service_id = ENV['TDX_SERVICE_ID'].to_i
end
Note: If you use Rails credentials (recommended), the gem will automatically configure itself and you don't need to create this initializer file.
Usage
Step 1: Mount the Engine Routes
Add the feedback gem routes to your application's config/routes.rb
:
# config/routes.rb
Rails.application.routes.draw do
# Your existing routes...
# Mount the feedback gem engine
mount LsaTdxFeedback::Engine => "/lsa_tdx_feedback", as: "lsa_tdx_feedback"
end
Step 2: Add the Feedback Modal and Assets (optimal placement)
For best performance and predictable ordering, include CSS in <head>
, render the modal markup in the body, and place JS just before </body>
:
<!-- app/views/layouts/application.html.erb -->
<head>
<%= lsa_tdx_feedback_css %>
<!-- your other tags ... -->
...
...
<%= csrf_meta_tags %>
<%= csp_meta_tag %>
<!-- etc. -->
...
...
...
...
</head>
<body>
...
<%= lsa_tdx_feedback_modal %>
<%= lsa_tdx_feedback_js %>
</body>
This avoids FOUC (flash of unstyled content) and ensures the script loads after the DOM.
Advanced Usage
Performance vs convenience
-
Optimal loading (recommended): Use the separate helpers so CSS loads in
<head>
and JS loads just before</body>
. This avoids FOUC and keeps asset order predictable. -
Convenience: Use
lsa_tdx_feedback
(all‑in‑one) for quick setup. It injects CSS/JS plus the modal where it’s called, which can delay CSS and is less ideal for performance.
Recommended placement (optimal)
<!-- app/views/layouts/application.html.erb -->
<head>
<%= lsa_tdx_feedback_css %>
<!-- your other tags ... -->
...
...
</head>
<body>
...
<%= lsa_tdx_feedback_modal %>
<%= lsa_tdx_feedback_js %>
</body>
You can also include components separately for more control over placement:
<!-- In your layout head section -->
<%= lsa_tdx_feedback_css %>
<!-- In your layout body section (before closing </body> tag) -->
<%= lsa_tdx_feedback_js %>
<!-- Include just the modal (assets must be included separately) -->
<%= lsa_tdx_feedback_modal %>
Or use the combined assets helper:
<!-- Include both CSS and JavaScript together -->
<%= lsa_tdx_feedback_assets %>
<!-- Include just the modal (assets must be included separately) -->
<%= lsa_tdx_feedback_modal %>
When to use explicit Rails asset tags
If you prefer explicit control, you can use Rails helpers directly:
<head>
<%= stylesheet_link_tag 'lsa_tdx_feedback', media: 'all', 'data-turbo-track': 'reload' %>
</head>
<body>
...
<%= lsa_tdx_feedback_modal %>
<%= javascript_include_tag 'lsa_tdx_feedback', defer: true, 'data-turbo-track': 'reload' %>
</body>
Use explicit tags when you need to:
- Set attributes like
defer
,async
,nonce
(CSP),integrity
,crossorigin
,media
, orpreload
- Control exact ordering relative to Bootstrap or your packs
- Swap delivery (CDN vs pipeline) or pin versions independently of the gem
- Integrate precisely with your asset setup (Importmap, Propshaft, Sprockets, etc.)
Convenience (all‑in‑one)
If you want a single helper that injects CSS, JS, and the modal where it’s called (good for quick trials or prototypes):
<!-- In your application layout (e.g., app/views/layouts/application.html.erb) -->
<%= lsa_tdx_feedback %>
Note: This may load CSS later than ideal and is less optimal for performance.
Customizing User Email
By default, LsaTdxFeedback tries to automatically detect the current user's email. You can customize this by overriding the current_user_email_for_feedback
method in your ApplicationController:
class ApplicationController < ActionController::Base
private
def current_user_email_for_feedback
current_user&.email_address # or however you access user email
end
end
TDX API Configuration
Required TDX Settings
- Client Credentials: You need OAuth client credentials from your TDX administrator
- Responsible Group ID: The TDX group that will receive feedback tickets
- App ID: Your TDX ticketing application ID (usually provided by your TDX admin)
Default TDX Values
The gem uses these default values based on University of Michigan's TDX setup:
- OAuth URL: see API documentation
- API Base URL: see API documentation
- Type ID: 28 (TeamDynamix)
- Form ID: 20 (Request Form)
- Classification: "46" (Request)
- Status ID: 77 (New)
- Priority ID: 20 (Medium)
- Source ID: 8 (Systems)
- Service ID: 67 (ITS-TeamDynamix Support)
You can override any of these in your configuration.
Feedback Categories
The modal includes predefined categories that automatically set ticket priorities:
- Bug Report → High Priority
- Urgent/Critical → Emergency Priority
- Suggestion/Enhancement/Feature → Low Priority
- General/Other → Medium Priority (default)
Styling
The gem includes completely self-contained CSS that won't interfere with your application's styles. All CSS classes are prefixed with feedback-gem-
to avoid conflicts.
If you need to customize the appearance, you can override the styles in your application:
/* Customize the trigger button */
.feedback-gem-trigger-btn {
background: #custom-color !important;
}
/* Customize the modal */
.feedback-gem-modal-content {
border-radius: 8px !important;
}
JavaScript
The gem includes self-contained JavaScript that initializes automatically. It handles:
- Modal show/hide functionality
- Form submission via AJAX
- Loading states and error handling
- Keyboard navigation (ESC to close)
- Mobile responsive behavior

Troubleshooting
Common Issues
-
"client_id is required" error
- Make sure you've configured your TDX credentials properly
- Check that your Rails credentials are accessible
-
Modal doesn't appear or form submission fails
- Ensure you've included
<%= lsa_tdx_feedback %>
in your layout -
Check that you've mounted the engine routes in your
config/routes.rb
- Check browser console for JavaScript errors
- Verify the
/lsa_tdx_feedback/feedback
endpoint is accessible - If using separate helpers, ensure CSS is in
<head>
and JS is before</body>
- Ensure you've included
-
Styling conflicts
- All LsaTdxFeedback styles are prefixed with
feedback-gem-
- Use browser dev tools to check for CSS conflicts
- All LsaTdxFeedback styles are prefixed with
-
OAuth/API errors
- Verify your TDX credentials are correct
- Check that your TDX instance URLs are correct
-
Ensure oauth_url does NOT include /token (e.g., use
https://your-tdx.com/oauth2
nothttps://your-tdx.com/oauth2/token
) - Ensure your responsible group ID exists in TDX
Debug Mode
Enable debug logging by setting the Rails log level:
# In development.rb or production.rb
config.log_level = :debug
This will log OAuth token requests and API calls for troubleshooting.
