Question

I’m generating json from a Rails app, and am filtering fields using the format.json and to_json methods. It is working fine, except the json does not have an object name. This is the Rails code:

format.json { render :json =>  @text.to_json(:only =>[:id,:language,:text_name,:text_type,:text_content])}

And a part of the json output:

[{"id":5,"language":"TR","text_name":"2.01 AY\u015eE'DEN MEKTUP","text_type":null},{"id":6,"language":"TR","text_name":"2.02 Ruya","text_type":null},{"id":7.... etc

Where I was thinking I would receive something indicating the name of the object (eg: “texts”). More along the lines of:

{"texts:"[{"id":5,"language":"TR","text_name":"2.01 AY\u015eE'DEN MEKTUP","text_type":null},{"id":6,"language":"TR","text_name":"2.02 Ruya","text_type":null},{"id":7.... etc

Answer 1

The following render line will produce the result you’re looking for:

format.json { render :json => { :texts => @text.to_json(:only =>[:id,:language,:text_name,:text_type,:text_content])}}
