💡 𝗧𝗶𝗽 𝗼𝗳 𝘁𝗵𝗲 𝗗𝗮𝘆 — 𝗗𝗷𝗮𝗻𝗴𝗼 𝗗𝗶𝗱 𝘆𝗼𝘂 𝗸𝗻𝗼𝘄? Django’s "Model.clean()" method lets you enforce 𝗰𝗿𝗼𝘀𝘀-𝗳𝗶𝗲𝗹𝗱 𝘃𝗮𝗹𝗶𝗱𝗮𝘁𝗶𝗼𝗻 at the model level. Unlike field validators, "clean()" can validate how multiple fields relate to each other — ensuring data integrity even outside forms. 🔧 𝗕𝗲𝘀𝘁 𝗽𝗿𝗮𝗰𝘁𝗶𝗰𝗲: Call "full_clean()" before saving when you rely on model-level validation, especially in custom save logic or scripts. Validation closer to the data = safer systems.
