How can I assign the results of a Rails “render json:” and “render_with” to a variable, for storage in a table?

原文 2015-09-05 05:31:13 2 1 ruby-on-rails/ ruby/ json/ active-model-serializers

I have some code rendering json as follows...

        serialized = ActiveModel::ArraySerializer.new(actions, each_serializer: Api::V1::ActionSerializer)
        render json: { actions: serialized }

What I need... is to turn serialized into a string so I can store it in a database record. serialized.to_s does not work.

How can I turn this #<ActiveModel::ArraySerializer:0x007fdfddc332b8> into a string representation of the JSON?

您可以使用ActiveSupport :: JSON＃encode来获取JSON的字符串表示形式。

ActiveSupport::JSON.encode(serialized)
