Sending a DELETE request from Sinatra

Question

I am trying to develop a RESTful Sinatra application. Now, I know how to respond to a delete request with something like

delete '/user/:id' do |id|
   #do something in the model
end

What I am interested in is how do I get to execute that method. I can't have link that does a DELETE instead of a GET, can I?

The only solution I found so far is sending a DELETE request via jQuery: How to send a PUT/DELETE request in jQuery?

I tried looking into different RESTful Sinatra projects on github but my Ruby knowledge is probably to limited to get how they are doing it.

Answer 1

Put following line in your code.

use Rack::MethodOverride

It will help you interpret post methods with parameter "_method" with value "delete" as put. Then you can write

delete '/user/:id' do |id|

Answer 2

I thinks it's like the Rails way. You need define a params '_method' with 'delete' value and add it on your form.

When you POST you form with this particular params, you do a DELETE request in sinatra.

Like :

<form action="/search" method="post">
  <div style="margin:0;padding:0">
    <input name="_method" type="hidden" value="delete" />
  </div>
</form>

It's the same with PUT method
