REST has some of its own verbs, or HTTP operations, for performing actions on resources. There are five in total: Get, Post, Put, Patch, and Delete. In this video, we'll take a closer look at these five REST HTTP verbs in Ruby on Rails 4, and also discuss some of the complexities and problems of these actions.
…In order to work with Rest in our application, we have to adopt some…new verbs that we can use, to talk about performing actions on our resources.…There are five verbs which are actually HTTP operations.…Get, Post, Put, Patch, and Delete.…And you can see I have those in the far left column of my table.…Get and Post you recognize as HTTP operations we see…when we get a URL or we post a form.…Get is for most links.…We're getting information back from the server.…
In our simple CMS we used Post for forms that create, update, and delete items.…However, in Rest, post is only used to create a new item.…When we want to update an existing item, we use Put or Patch.…Put is used when we want to replace the resource completely.…Patch is for when we want to make changes to just a portion of the resource.…Rails used to perform updates using Put, but starting in Rails 4, it uses Patch.…Which is more technically correct, but…it still supports Put for backwards compatibility.…
Lastly, when we want to delete an item, we use Delete.…
