In the enchanting realm of code, the Wishmaster embarked on yet another day of exploration and mastery. As the sun rose on Day Six, the Wishmaster focused on the mystical art of tag management, seeking to weave a more intricate tapestry of functionality within the beloved blog. The objective was clear: empower the users with the ability to add tags to their posts and edit existing entries, ensuring that every thought and creation was appropriately adorned.

With a flourish of creativity, the Wishmaster conjured the necessary updates to the create_post and view_post routing. The HTML pages transformed to accommodate the whims of tag selection, allowing users to choose from a gallery of tags to enrich their posts. The Wishmaster was particularly pleased with the way the tags were elegantly displayed, reminiscent of cherished relics, each waiting to impart its unique essence to the narrative.

However, as with any grand undertaking, challenges arose. The Wishmaster found themselves grappling with the nuances of type handling in Python when retrieving selected tags. A moment of confusion ensued, but with the deftness of a seasoned sorcerer, the Wishmaster implemented a robust solution, ensuring that no empty strings would sully the sacred post_tags table.

With the new tagging system in place, it was time to venture back to the manage_tags page. Here, the Wishmaster sought to unveil all posts linked to a particular tag, further enriching the user experience. The implementation was seamless, and with a few deft tweaks to the JavaScript, the details of each tag unfolded like petals, revealing the treasures hidden within.

As the day progressed, the Wishmaster turned their attention to the edit_post feature, preparing to allow the admins to refine their creations. The addition of a delete button, adorned with a whimsical red 'X,' was a fitting touch, providing a quick means of disposing of unwanted musings. Yet, as always in the world of magic and coding, unforeseen obstacles emerged. The mysterious 405 error shrouded the delete functionality, but with careful deliberation and a sprinkle of logic, the Wishmaster unraveled the threads of error, ensuring the delete operation would redirect as desired.

With each passing moment, the Wishmaster grew more attuned to the intricate dance of code and logic. The day culminated in the satisfaction of a well-crafted blog, now brimming with features that promised to enhance the storytelling experience. Through diligent testing and careful adjustments, the Wishmaster learned the value of keeping one’s code tidy and the importance of robust error handling.

As the sun dipped below the horizon, the Wishmaster reflected on the day’s journey. The successes and challenges were mere stepping stones in the grand adventure of coding. With a heart full of determination and a mind sharpened by experience, the Wishmaster was ready to forge ahead, knowing that every line of code was a spell, every bug a lesson, and every triumph a celebration of their magical journey.
