Access files on AWS S3 bucket using aws-sdk-s3 with Rails 6

This is a quick post to share few easy methods to access files on AWS S3. The below custom utility methods uses  aws-sdk-s3 Firstly lets define a constant to access files on S3 -  ##to manage S3 Resources S3 = Aws::S3::Resource.new( region: "YOUR-REGION", access_key_id: "YOUR-AWS-KEY", secret_access_key: "YOUR-AWS-SECRET") ##to query S3 S3_client = Aws::S3::Client.new( access_key_id: configatron.aws.s3.credentials.access_key_id, secret_access_key: configatron.aws.s3.credentials.secret_access_key, region: configatron.aws.s3.region ) Now, lets use the S3 OBJECT to access files in different ways -  1. Get all files in a S3 FOLDER     ##this gives a array of file paths present in the folder specified by prefix attribute          s3objects = S3.bucket("my-output-bucket").objects({prefix: "/inputs/any-random-user-folder"}).collect(&:key) ##you can also delete the file if found ##eg: s3o

Setting Axios to put/post dynamically

How I achieved it -  - Firstly for new object, it worked smoothly and I wanted to reuse the same component again for edit/update too. - I sent the existing values as props and saved them into the corresponding states. - I reused the existing method ( axios server call ) so that it dynamically POST/PUT as needed.This is show below -         //this method calls post/put dynamically - simple code here..no rocket science methodCall = () => { const { Id, editable, details } = this.state; //check if new or existing record if (editable) { return API.put(`/post/${Id}`, details); } else { return API.post("/post", details); } }; //call this method onClick/onSubmit - as you want to handleSubmit = (event) => { event.preventDefault(); //call dynamic this.me
