undefined method `stringify_keys!' ruby on rails

Question

I have this code:

def addcar
  @car = Car.new(params[:car])
  render :action => \'list\'
end

<% @allcars.each do |cell| %>
  

    <%= l         


        

Answer 1

in the addcar method, you try to create a new object (create method) while transfering just a string to it (params[:car] which apparently is set to "Honda").

create expects to get an attributes hash and to stringify it's keys for the column names.

If you have a column named name in your cars table then try this:

@car = Car.new(:name => params[:car])
