How to permit an array json with Rails?

Question

For json

{ "version":"1", "configs":[ { "title":"Good", "body":"Body" }, { "title":"Good", "body":"Body" } ] }

How to permit it with Rails' params.permit in controller?

I tried

 params.permit( config_setting: [ :version, configs: [ :title, :body, ] ], )

But seems not right.

Currently you are permitting a json with the following structure:

{ "config_setting": [ { "version":"1", "configs":[ { "title":"Good", "body":"Body" }, { "title":"Good", "body":"Body" } ] } ] }

Just add config_setting node to the data or adjust your strong params block to:

params.permit( :version, configs: [ :title, :body, ] )
