Hi, I am using attr_accessor attributes in model class and assigning the values to attr_accessor dynamically in controller. And am sending the data object to display in Yaml format. I am getting the response along with changed_attributes but I don''t want changed_attributes details in my response. build Model code class Test < ActiveRecord::Base attr_accessor: t_1, t_2, t_3, t_4 end In Test Controller code: #build is controller object tb = ["[5, 30.14]","[0, 12.0]","[1, 11.0]","[2, 11.0]"] $i=1 while $i <= tb.length do $tbVal = "t_#{$i}" build["#{$tbVal}"] = tb[$i-1] $i += 1 wants.yaml { render :text => tb.to_yaml, :content_type => "application/x-yaml", :layout => layout} Ouput: --- ! ruby/object:Test attributes: build_1: "[5, 30.14]" build_2: "[0, 12.0]" build_3: "[1, 11.0]" build_4: "[2, 11.0]" attribute_cache: {} changed_attributes: build_1: build_2: build_3: build_4: I am getting the output with "changed_attributes" with empty values and I don''t want to display the changed_attributes in Yaml. Could anyone please help me to remove the changed_attributes data from yaml response?
