It follows a similar pattern as Retrieve ( -get) but using db.Query: And when I’m inserting records, the first format in the list will be used to transform my time.Time to a database string. So, that list of priority order formats drives the conversion process.Īs long as my dates strings are in one of these formats, they will get correctly converted when I read them out. I need to install SQLite3 and SQLite-utils:įunc (c *Activities) Retrieve(id int) (api.Activity, error) The first thing I need is to set up my dev environment. it’s the type of feature that is simple to do with a SQL backend. And once I have that, I’ll add the -list command to my command line client and add an end point for it. My plan is to add SQLite persistence to the backend service so that my workouts aren’t lost if the service goes down. I’m going to be using sqlite3, but I’ll add lots of headings, so you can skip ahead if sqlite is not your thing. If you’re curious about the basics of storing persistent data into a SQL database using Golang, this tutorial will be helpful for you. Last time I made a command-line client to connect to the JSON Service, but today is all about database persistence using database/sql. I’m an experienced developer, learning Golang by building an activity tracker. So if you’re interested in a simpler way to build then check us out. Earthly is open-source and written in go. We make building software simpler and therefore faster.
