Getting devise to return json data when signing out

Hi all,

In curl (the command line program), I can successfully log a user in
using devise:

def create
respond_to do |format|
format.json {
if user_signed_in?
return render :json => {:success => true, :errors =>
[“Already logged in.”]}
end
resource = warden.authenticate!(:scope =>
resource_name, :recall => “#{controller_path}#failure”)
return sign_in_and_redirect(resource_name, resource)
}
end
end

def sign_in_and_redirect(resource_or_scope, resource=nil)
scope = Devise::Mapping.find_scope!(resource_or_scope)
resource ||= resource_or_scope
sign_in(scope, resource) unless warden.user(scope) == resource
return render :json => { :success => true, :redirect =>
stored_location_for(scope) || after_sign_in_path_for(resource)}
end

def failure
return render :json => {:success => false, :errors => [“Login
failed.”]}
end

def logged_in
return render :json => {:success => false, :errors => [“Already
logged in.”]}
end

However, once they are logged in, they are never logged out. So I want
to be able to log out via curl and return json (curl is my testing
devise right now, but ultimately I intend this to work through the
iphone).

I add this to users/session controller:

def destroy
respond_to do |format|
format.json {
return sign_out_and_redirect(resource_or_scope)
}
end
end

def sign_out_and_redirect(resource_or_scope)
scope = Devise::Mapping.find_scope!(resource_or_scope)
if Devise.sign_out_all_scopes
sign_out_all_scopes
else
sign_out(scope)
end
return render :json => {:status => :signed_out}
end

I get a “udefined method or variable resource_or_scope”. The problem
is if i define this sign_out_and_redirect method in the application
controller, as another forum recommended:

it never gets called when I do:
http://localhost:3000/users/sign_out.json.
And no json data is ever returned.

And through curl, a strange thing happens with this:

curl -X POST http://localhost:3000/users/sign_out.json -d ‘’

it says no route for “users/sign_out”, which is odd it says that,
since users/sign_out gets invoked fine on html page.

thanks for response

I also asked this on stackoverflow:

I am finding it difficult to resolve this issue.
