As dusk descended over the Wishmaster’s code-laden workshop, an air of mystical anticipation filled the room. Tonight, the Wishmaster’s challenge was to breathe life into the intricate web of a restaurant order system, where entrees, sides, and modifications all intermingled in an ever-shifting arcane structure. The task ahead would require skillful handling of backend spells and front-end incantations to ensure each mod obeyed the wielder’s intent.

At the heart of this evening’s magical undertaking was the mysterious dichotomy of entree mods and side mods. The Wishmaster knew that each order, especially the sides, had a tendency to wander into unexpected territories, particularly as layers of modifications accumulated. A restless energy surged within the code, for each time a new side was summoned, lingering enchantments from previous modifications began to interfere, causing all manner of chaos. To tame this, the Wishmaster needed to create an incantation that would not only properly store each side’s modifications but would clear any previous traces when a new side was chosen.

The Wishmaster’s first spell involved a line of code meant to reset the side modifications: entree.side_mods = json.dumps([]). But despite its simplicity, the spell seemed to fizzle, its effects lost somewhere in the tangled layers of data. A closer examination of the backend’s ritual chamber revealed that the Wishmaster’s invocation was not being committed to the database’s grimoire. After reinforcing the code with db.session.commit(), the spell took hold, purging any residual side enchantments as each new side was summoned.

With the backend magic stabilized, attention turned to a hidden trap within the front-end enchantments. The logSelection function, which directed modifications to the right route, was indiscriminately adding every new incantation to the entree itself. This unbridled approach, it seemed, was responsible for the chaotic blending of entree and side mods. A toggle was added, a dual-sided relic in the form of the isModifyingEntree variable, which directed each modification spell to either the entree’s mods or the side’s side_mods as needed. The toggle ensured that mods were no longer bound to the same domain, maintaining the distinction between the Wishmaster’s targets.

The Wishmaster then encountered a common trap of the enchanted workshop—multiple event listeners layered upon one another, each triggered with every call to the displayModIntensity incantation. With each invocation, the mod-target listeners multiplied, resulting in unpredictable behavior. A powerful solution lay in the binding magic of an immediately-invoked function expression (IIFE), which set these listeners only once upon the page’s first render. This approach ensured that event listeners no longer multiplied and that each button’s purpose was clear and singular, reloading the appropriate ingredients and mods each time the target was changed.

As the night wore on, the Wishmaster observed the flow of energy between backend and frontend, learning how vital the balance between them truly was. The boundaries between entree and side, the importance of clearing data at key moments, and the need to define code that only runs once—each of these lessons became part of the Wishmaster’s evolving spellbook.

In the dim glow of the workshop, with the system now obedient to its master’s will, the Wishmaster closed the tome of code with a satisfied smile. The evening had yielded its lessons: precision in intent, clarity in separation, and the importance of setting boundaries for each spell’s domain. With this newfound wisdom, the Wishmaster’s system held firm, ready for the orders of the day.
