Ways to fix issue 2003 (HY000): Unable to connect to MySQL server 'db_mysql:3306' (111)

I recently tried to containerize my FastAPIPython server (also for replication/doubling purposes).

Experiment with sorting after query limit

So this is my first question here, please forgive me if something is wrong. I'm trying to make a sort query based on constraints. So there is a Customers table with 90 records. I want to first perform a query limited to 3 records, and then sort the results of this query by a column called ContactName. I think this might be a nested query. Nested queries run fine in SQLServer, but don't know how to implement it in MySQL. Limit query: Select*fromcustomerslimit

CSS Grid: Create new row when child content overflows column width

I have a two column layout based on CSS grid. When the content of the second column exceeds 1fr I want to create a new row. As it currently stands, the content simply overflows the column. One requirement of this layout is that the items in the right menu column are in one row. I achieve this with: .right-menu{...grid-auto-flow:columndense;...} If I remove the grid-auto-flow attribute, the overflow stops. However, the items are now stacked into multiple rows, which is not what I want. I also tried converting .ri

Shortest way to convert all PHP types to string

I'm writing a general system that I hope can one day be applied to fields like medicine (i.e. it's "scientific"). I think the best way is to represent all the data in php with strings (true will be "true", false will be "false" and so on). The reason for this is that in php any value has a unique string representation (such as the php code itself). I post this question to speed up the design process of this program. Some values are easily converted to strings: numbers, booleans, etc. Some are not easy: objects, arrays, resources. I think the transfer object and

Prompts are to AI as menus are to chefs

Course Introduction：1. Introduction Hello everyone, I am Xiao ❤, a 985 non-scientific programmer who has been wandering around the world for many years. I have worked as a backend development engineer in state-owned enterprises, large Internet companies and start-up companies. I was at home last weekend and it was raining outside, so I wanted to know the weather conditions in the past few days. It happened that my phone was charging, so I planned to ask the smart speaker Xiaoyi, but by chance, I opened my mouth and blurted out: "Xiaoyi, Xiaoyi, is the weather good?" As a result, it said to me: "Whether it's sunny or rainy" , I hope you can have a good day!" This kind of vague instruction problem is not limited to smart furniture. AI large models that are widely used today also face similar dilemmas. Although these AIs possess higher levels of intelligence, they also require clear instructions to ensure correct operation. Let's look at writing
