Dynamic Table Row

I’m playing with rails and RJS,

What I want I think sounds simple - but I can’t seem to figure it out.

So basically I have a Countries Model, which joins on Cities Model.

I want to display a list of countries in a select, when you select a
country it shows all the cities in that country.

That works just fine - the issue I have is to add the data in tables.

I have right now a index page

Listing countries

Please select country <%= select_tag(:id , options_from_collection_for_select(@countries, :id, :country)) %>
<%= observe_field :id, :frequency => 0.25, :url => {:controller => "countries", :action => 'show'}, :with => 'id' %>

So when the user chooses a country it gets all the cities of that
country, now all I want to do is add a new row to the existing table,
with a new select containing the cities. My show.rjs does

page.replace_html :show_cities, :partial => ‘show’, :object => @country

And then the partial is

Please select city <%= select_tag(:id , options_from_collection_for_select(@country.cities, :id, :title)) %>

And it displays the data, but not in the exiting table…I know this
probably isn’t strictly rails as its javascript/html but maybe someone
can help… All I want is to be able to add new rows when the data is
available?

Browsers are often a bit finnicky about inserting stuff into tables.
Strictly speaking you shouldn’t have a div there - a tr should contain
td tags and things like that. In the past I’ve also found that
inserting a tbody with some rows to work better than just inserting
rows.
