On the dawn of the fifth day, the Wishmaster ventured forth to weave a new layer of enchantment into the tapestry of their digital domain. The quest for the elusive tagging system began, a powerful tool meant to organize the vast realms of posts scattered across the blog like forgotten spells. With a steady hand and a mind full of ideas, the Wishmaster embarked on the journey to update the database, eager to create connections between posts and tags, allowing for a richer and more dynamic experience for future visitors.

As the lines of code were crafted, the Wishmaster encountered the challenges of populating the tags in the tags-container. With each incantation typed into the terminal, the notion of dynamically generating the tags became clearer. A plan emerged: to structure the tags in a dictionary, linking each tag to its respective card, creating a more responsive and magical interface.

The Wishmaster then turned to the creation of a new tag, crafting a form that would allow for the birth of new identifiers in this mystical world. However, as they summoned the AJAX spell to handle the creation, a specter of confusion emerged—JSON versus form data. This caused a ripple of uncertainty, a momentary falter in the flow of magic.

Yet, with the wisdom of the ancients at hand, the Wishmaster forged ahead, integrating the JSON incantation seamlessly into the existing spells. The creation process was further refined to ensure that duplicate tags could not tarnish the realm. In doing so, the Wishmaster learned the significance of robust validation—a crucial aspect of maintaining harmony in the magical order.

As the sun climbed higher in the sky, the challenge of deleting tags approached. A task that once seemed daunting began to take shape. The Wishmaster envisioned a world where tags could be effortlessly removed, a power only granted to the worthy, those with the admin role. However, the dark shadow of a misfired deletion spell lingered, as both creation and deletion forms clashed in a chaotic dance, each vying for dominance.

But with resolve and determination, the Wishmaster restructured the spells, ensuring that the tags would vanish from sight when commanded. The final enchantment took form—when a tag was deleted, the tags-container would refresh, displaying the updated list without a hitch, as if the very essence of the tags had been conjured anew.

In the throes of battle, the Wishmaster discovered not just the intricacies of coding, but also the emotional ebb and flow that accompanies the developer's journey. The day was fraught with challenges, yet each obstacle presented an opportunity to learn and grow. With every line of code and each moment of frustration, the Wishmaster embraced the trials of their craft, knowing that even on the toughest days, they were progressing toward mastery.

As the day drew to a close, the Wishmaster looked upon the code with newfound clarity, eager to continue their quest in the realms of tags and posts, fortified by the lessons learned and the magic they had woven into their Codex.
