Like Button Indicator Doesn't Work At First Render In Recently Viewed Section
Bug Description
The like button indicator fails to work as expected in the recently viewed section of the home page. When an itinerary is viewed and liked/saved, the like button should turn red, indicating that it is already liked by the logged-in user. However, in the recently viewed section, the like button remains unchanged even though the isLiked attribute value is true.
To Reproduce the Issue
Step 1: Access the Home Page
Navigate to the home page of the application.
Step 2: Like an Itinerary
Click on the like button of an itinerary to like it.
Step 3: View the Liked Itinerary
Click on the liked itinerary to view its detail page.
Step 4: Check the Recently Viewed Section
The liked itinerary should be displayed in the recently viewed section of the home page.
Step 5: Verify the Like Button
The like button of the liked itinerary in the recently viewed section should be red, indicating that it is already liked by the logged-in user.
Expected Behavior
A like button should turn red when an itinerary is already liked by the logged-in user. This behavior should be observed in the recently viewed section of the home page.
Possible Causes
1. Inconsistent State
The like button's state might not be updated consistently across the application, leading to the issue.
2. Rendering Issue
There might be a rendering issue that prevents the like button from turning red in the recently viewed section.
3. Data Synchronization
The data might not be synchronized correctly between the recently viewed section and the itinerary's detail page, causing the like button to remain unchanged.
Troubleshooting Steps
1. Inspect the Like Button
Use the browser's developer tools to inspect the like button's HTML and CSS to identify any potential issues.
2. Verify the isLiked Attribute
Check the value of the isLiked attribute for the liked itinerary in the recently viewed section to ensure it is set to true.
3. Check for Rendering Issues
Verify that the like button is being rendered correctly in the recently viewed section by checking the application's rendering logic.
4. Synchronize Data
Ensure that the data is synchronized correctly between the recently viewed section and the itinerary's detail page.
Conclusion
The like button indicator fails to work as expected in the recently viewed section of the home page. To resolve this issue, it is essential to identify and address the root cause, which could be related to inconsistent state, rendering issues, or data synchronization problems. By following the troubleshooting steps outlined above, developers can diagnose and fix the issue, ensuring that the like button turns red when an itinerary is already liked by the logged-in user.
Recommendations
1. Improve State Management
Implement a robust state management system to ensure that the like button's state is updated consistently across the application.
2. Optimize Rendering
Optimize the rendering logic to prevent any potential issues that might cause the like button to remain unchanged.
3. Enh Data Synchronization
Implement a data synchronization mechanism to ensure that the data is updated correctly between the recently viewed section and the itinerary's detail page.
