Question

I’m using JBuilder as to return some JSON. I have a index.json.jbuilder that generates the data, and I need to render it to a string. However, I’m not sure how to do this, since: @my_object.to_json and @my_object.as_json don’t seem to go through JBuilder.

How could I render the JBuilder view as a string?

I am rendering a collection of users as a json string in the controller like so:

#controllers/users_controller.rb
def index
  @users = User.all
  @users_json = render_to_string( template: 'users.json.jbuilder', locals: { users: @users})
end

#views/users/users.json.jbuilder
json.array!(users) do |json, user|
  json.(user, :id, :name)
end
