Hey Humans! Its 12:57PM, Just solve the error for which I cried and tried a lot about in the early morning almost 5AM, after lots of shit I gone to sleep but now I actually solve it and the error is so silly probably it happened because of my sleepy eyes missed the line " posts = Posts.query.all() " to put it in admin_user's code. That's my bad, I was so frustrated for this error since I wake up. Super relaxed right now. Lots of code to do. Bye/>
