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). Before, I had just a MySQL server in a Docker container and everything was fine, but when I also made my web server a service, it couldn't connect to the MySQL server, so now the application doesn't work. Below is the code snippet of the server database initialization connector in the application fromfastapiimportFastAPIimportmysql.connectorapp

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

Over 70% mAP for the first time! GeMap: Local high-precision map SOTA refreshed again

Course Introduction：Written before: The author’s personal understanding is that constructing vectorized high-precision maps based on sensor data in real time is crucial for downstream tasks such as prediction and planning, and can effectively make up for the poor real-time performance of offline high-precision maps. With the development of deep learning, online vectorized high-precision map construction has gradually emerged, and representative works such as HDMapNet, MapTR, etc. have emerged one after another. However, existing online vectorized high-precision map construction methods lack exploration of the geometric properties of map elements (including the shape of elements, vertical, parallel and other geometric relationships). Geometric properties of vectorized high-precision maps Vectorized high-precision maps highly abstract the elements on the road and represent each map element as a two-dimensional point sequence. The design of urban roads has specific specifications, for example, pedestrian
