This is how my edit.rhtml file looks

<h1>Editing environment</h1>

<%= start_form_tag :action => 'update', :id => @environment.id %>
        Pupose: <%= text_field_tag('purpose',@environment.purpose)
%><br> <br>
        Environment: <%=
text_field_tag('environment',@environment.environment) %><br> <br>
        Machine: <%= text_field_tag('machine',@environment.machine)
%><br> <br>
        Application: <%=
text_field_tag('application',@environment.application) %> <br> <br>
        OS: <%= text_field_tag('os',@environment.os) %> <br> <br>
        PrivateIP: <%=
text_field_tag('privateip',@environment.privateip) %> <br> <br>
  <%= submit_tag 'Edit' %>
<%= end_form_tag %>

<%= link_to 'Show', :action => 'show', :id => @environment %> |
<%= link_to 'Back', :action => 'list' %>

This is how my update controller looks

  def update

    @environment = Environment.find(params[:id])

    if @environment.update_attributes(params[:environment])

      flash[:notice] = 'Environment was successfully updated.'

      redirect_to :action => 'show', :id => @environment

    else

      render :action => 'edit'

    end

  end


When I try to update a record I get following error

 NoMethodError in Environment#update

undefined method `stringify_keys!' for "BSP-2.3.1 Ringback":String
