Enable accessing pseudo-attributes from a Rails model in JavaScript as well

Check out this example of a Rails model:

class Customer < ActiveRecord::Base

   attr_accessible :firstname, :lastname, :email, :phonenumber, :company_id

   def name
      "#{self.lastname} #{self.firstname}"
   end

   scope :search_by_name, lambda { |q|
       (q ? where(["firstname LIKE ? or lastname LIKE ? or (firstname || ' ' || lastname) like ?", '%'+ q + '%', '%'+ q + '%','%'+ q + '%' ])  : {})
   }

end

When I retrieve a JSON object of that model using ajax, I face a challenge. I need to access the name attribute in my autocomplete text field without combining firstname and lastname in one database field.

Do you have any suggestions on how to access the name attribute in JavaScript or how to include the name attribute in the JSON object? I'm looking for the most efficient method.

Answer №1

It is possible to accomplish a similar task with the following code: format.json { render :json => @client.to_json(:methods => :name)}

Answer №2

When crafting the JSON response in your controller, you have the ability to customize what data is sent back. By customizing the JSON output, you can specify the exact structure and content you want to send.

One way to do this is by using a syntax like the following:

render :json => { :customer => { :name => @customer.name, :email => @customer.email } }

Alternatively, you can explore using tools like https://github.com/rails/jbuilder if you anticipate sending more intricate JSON responses.
