How to Set Up a Magento 2 Module for Customizing Wishlist Grid?

1. Create Module Directory Structure

• Set up the main folder structure under app/code/Vendor/WishlistGrid/ directory path.

• Create the etc folder to store XML configuration files and module declarations.

• Add the Controller folder that processes admin page requests and user actions.

• Include the Model folder containing business logic and data operation classes.

• Build the view folder to store UI components, templates, and layout files.

2. Register the Module

• Create registration.php in the root directory to declare your module to Magento.

• Use the ComponentRegistrar class to handle the registration process the right way.

• Magento scans and loads this file during the system initialization phase.

• The file connects your module to Magento's module management system.

3. Define Module Configuration

• Create module.xml in the etc folder with the module name and setup_version attribute.

• Declare dependencies on the Magento_Wishlist module for core wishlist functions.

• Add the Magento_Customer dependency to access customer data and profiles.

• Include Magento_Backend and Magento_Ui modules for admin grid features.

• Use semantic versioning format (major.minor.patch) for version numbers.

4. Specify Dependencies

• List all required packages in composer.json for the module installation to work. For example, include dependencies like:

magento/module-wishlist": "103.0.8,

magento/module-customer": "103.0.8,

magento/module-backend": "103.0.8,

magento/module-ui": "103.0.8

• Include optional packages that add extra features when installed on the system.

• Identify conflicting packages to prevent installation problems and errors.

• Add development dependencies for testing and quality assurance processes.

5. Enable Module in Magento

• Run the bin/magento module:enable Vendor_WishlistGrid command to activate the module.

• Execute the bin/magento setup:upgrade command to run database installation scripts.

• Clear cache with the bin/magento cache:flush command for fresh configuration loading.

• Check module status with bin/magento module:status command to confirm successful activation.

• Check recipient email addresses before sending messages.

3. Add Notification Trigger

• Create a cron job in crontab.xml to schedule segment notifications.

• Set trigger conditions based on wishlist activity by customer group.

• Let the admin toggle to activate or deactivate notifications.

• Log notification history for tracking and audit purposes.

4. Set Email Template

• Add email_template.xml in the etc directory to define the notification format.

• Include fields for customer names and wishlist items.

• Configure template styles to match store branding guidelines.

• Test template rendering with sample segment data.

5. Check Notification Delivery

• Test email dispatch with sample customer segment data sets.

• Check that the email content displays the correct wishlist item details.

• Confirm notifications reach the intended segment recipients.

• Track cron job execution for consistent delivery timing.

Configuring Wishlist Segment Report Access

1. Define Report Route

• Create routes.xml file in etc/adminhtml directory with a unique report identifier.

• Set the front name to construct clear URLs for report access.

• Link the route to the module for accurate controller processing.

• Use an admin router for built-in security protections.

2. Create Report Controller

• Confirm unauthorized users receive access denied messages.

These database tables work together to support wishlist queries:

Table Name	Primary Key	Foreign Keys	Purpose	Critical Fields
wishlist	wishlist_id	customer_id	Stores the main wishlist data	updated_at, shared, customer_id
wishlist_item	wishlist_item_id	wishlist_id, product_id	Individual wishlist items	added_at, description, qty
customer_entity	entity_id	group_id, store_id	Customer account records	email, firstname, lastname
customer_group	customer_group_id	-	Defines customer segments, referenced by customer_entity via group_id	customer_group_code, tax_class_id
catalog_product_entity	entity_id	-	Stores product data, referenced by wishlist_item via product_id	sku, type_id, created_at
cataloginventory_stock_item	item_id	product_id	Inventory stock levels	qty, is_in_stock, manage_stock

Testing and Performance Optimization

1. Verify Grid Display

• Check grid renders without any JavaScript console error messages.

• Test all columns show data using the correct display formats.

• Confirm filter inputs respond to user actions without delays.

• Check pagination displays accurate total record count numbers.

2. Test Customer Group Filter

• Check that each segment filter returns the correct customer sets.

• Test different filter combinations to work without data conflicts.

• Check empty results display helpful user messages. For empty wishlists, make sure the grid displays a 'No results found' message.

• Confirm filter settings persist across page navigation actions.

3. Check Data Accuracy

• Compare grid output data against direct SQL query results.

• Check export files contain complete and accurate data sets.

• Test edge cases, including empty wishlists and null values. For null values, use COALESCE in SQL queries, e.g.,:

COALESCE(customer_group_code, 'Unknown')

• Check that timezone handling works right for all date fields.

4. Database Query Optimization

• Before adding new indexes, check for existing ones to avoid redundancy. Then, add database indexes on columns used in join operations.

• For example:

ALTER TABLE wishlist ADD INDEX idx_customer_id (customer_id);

ALTER TABLE wishlist_item ADD INDEX idx_wishlist_product (wishlist_id, product_id);

ALTER TABLE customer_entity ADD INDEX idx_group_store (group_id, store_id);

• Use the EXPLAIN command to identify slow query components.

• Limit SELECT statements to fetch the required data fields.

• Set up query caching for repeated data requests.

Note: You need SQL query access to add indexes and perform optimization.

5. Verify Scalability

• Load test using production-level data volumes and user counts.

• Check response times during peak usage period simulations.

• Track memory consumption during large data export operations.

• Test concurrent user access patterns and connection limits.

FAQs

1. How do I troubleshoot the filter for the Magento 2 grid performance issues?

Review the SQL queries generated by your filter in the collection’s query log. Verify index usage on filtered columns. Review the argument configuration in your collection class. Poor performance often stems from missing indexes or incorrect join definitions.

2. Can I track wishlist conversion rates by customer segment?

Yes, build conversion tracking into your wishlist grid module. Join the order tables with wishlist data to see sale rates. Track which segments convert wishlists to sales most often. Export this data for marketing analysis.

3. What's the approach to add a custom filter to the Magento grid?

Define a filter in Magento 2 by modifying your collection class. Add proper PHP namespace structure for the organization. Configure the filter for the product grid using virtual types. This approach maintains a clean code architecture.

4. How do I handle deleted products in wishlist grids?

Check product status before displaying wishlist items. Add validation to skip deleted or disabled products. Show a message when products become unavailable. This prevents broken links and data accuracy.

5. Can wishlist grids work with multi-store setups?

Yes, filter wishlists by store view using the store_id field. Each store can have unique customer segments. Configure separate ACL permissions per store. Admin users see only their assigned store data.

6. How do I schedule automatic wishlist reports for marketing teams?

Create cron jobs to generate segment reports. Schedule daily or weekly exports based on needs. Send reports via email to marketing managers. Include trend analysis comparing current and previous periods.

7. What happens to wishlist data during customer group changes?

Wishlist items remain linked to customers when groups change. Historical data stays intact for analysis. New wishlist additions reflect the updated segment. Configure your joins to track both current and historical segments.
