Question

I’m sending json request via curl to my local web server

curl -H 'Content-Type: application/json' -d {"name":"Stanford University", "subdomain":"stanford"} http://localhost:3000/rest/v1/groups.json

But in my rails app in params i’m getting

Parameters: {"name"=>"Stanford University", "subdomain"=>"stanford", "group"=>{"name"=>"Stanford University", "subdomain"=>"stanford"}}

Where did that hash group came from, and how do i controll it?

Answer 1

Look in config/initializers/wrap_parameters.rb. You likely have wrap_parameters enabled for JSON requests.

You can disable this option in the above file with

wrap_parameters false
