Question

I am being passed in a json body for a post request, but i’m not sure the best way to map this json body to request params in rails:

{
   username: "example-user",
   password: "password",
   email: "[e-mail]",
}

and in the controller i wish to acccess params[“username”],
is this possible? how should i do it?

Answer 1

see the guides for a comprehensive information.

you can simply access to params[:username] or even params['username'] since params is a HashWithIndifferentAccess.

Note that you can easily inspect the params using the debugger gem, or just slam a raise in your controller action to see them on the error page when in development mode.
