Django Json Field
سال‌هاست که ذخیره سازی داده‌ها به شیوه رابطه‌ای بهترین و رایج ترین شیوه ذخیره سازی است با این وجود در سال‌های اخیر و با معرفی مفهوم NoSQL شیوه‌های دیگری نیز مطرح شده اند که پرکاربردترین آنها Document یا ذخیره داده به شکل JSON است. ابزارهای مختلفی مانند mongodb در این فضا رشد کرده‌اند اما امروزه اغلب دیتابیس‌های رابطه‌ای به شما امکان ذخیره و بازیابی این نوع از داده‌ها را می‌دهند و شاید بتوان گفت بهترین آنها PostgreSQL است. در این ویدیو ابتدا شیوه‌ اجرای پستگرس از طریق داکر را شرح دادیم و سپس با اتصال به آن یک دیتابیس و یک جدول ساختیم که بتوان داده‌های JSON را نیز در آن ذخیره کرد. سپس همان رویکرد را بر روی جنگو و با استفاده Django Json Field پیاده سازی کردیم و چند مثال از query داده‌ها را بررسی کردیم.

Should You Buy Bitcoin?

In general, many financial experts support their clients’ desire to buy cryptocurrency, but they don’t recommend it unless clients express interest. “The biggest concern for us is if someone wants to invest in crypto and the investment they choose doesn’t do well, and then all of a sudden they can’t send their kids to college,” says Ian Harvey, a certified financial planner (CFP) in New York City. “Then it wasn’t worth the risk.” The speculative nature of cryptocurrency leads some planners to recommend it for clients’ “side” investments. “Some call it a Vegas account,” says Scott Hammel, a CFP in Dallas. “Let’s keep this away from our real long-term perspective, make sure it doesn’t become too large a portion of your portfolio.” In a very real sense, Bitcoin is like a single stock, and advisors wouldn’t recommend putting a sizable part of your portfolio into any one company. At most, planners suggest putting no more than 1% to 10% into Bitcoin if you’re passionate about it. “If it was one stock, you would never allocate any significant portion of your portfolio to it,” Hammel says.
