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).

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

The panel will be mass-produced in April. It is reported that the Google Pixel Fold 2 mobile phone has an external screen of 6.29 inches and an internal screen of 8.02 inches.

Course Introduction：According to news on March 13, Rose Young, CEO of the screen supply chain consulting company DSCC, recently tweeted that the previous revelations about Google’s Pixel Fold 2 folding screen mobile phone were wrong. He said in a tweet that the internal screen size of Google Pixel Fold2 folding screen mobile phone is 8.02 inches and the external screen size is 6.29 inches, and the panel will begin mass production in April this year. Some users question this and believe that if the inner screen is 8 inches, the outer screen should be at least 6.5 inches. Otherwise, it means that the borders around the outer screen are very thick and cannot compete with domestic mobile phone manufacturers. Ross Young's reply was that the external screen of the Pixel Fold 2 phone is very wide, just like the Pixel Fold 1.
