Hello ,
Use an Observe_field , so that you can have the country selected as a
parameter and with the help of the country name u can extract the respective
cities from the database
The following is the code snippet I have used. Might be of some help to u.
My View Code:
----------------------
<%= form_remote_tag(:update =>"update_div", :url => { :action => :register}
) %>
<p>
<label for = "country">Country</label> <br />
<%= select_tag id="user_country",
country_options_for_select(selected = nil,
priority_countries = ["Select One", "India", "USA", "Pakistan",
"Nepal", "China"]) %>
</p>
<%= observe_field("user_country", :url => { :controller => "login",
:action => "check_state"}, :update => "update_list", :with => "country")%>
<div id ="update_list" >
<p>
<label for = "state">State</label> <br />
<%= select("user",:state, %w{ -- }, :class => "select_state") %>
</p>
</div>
</form>
Controller Code:
----------------------------
def check_state
@result = Country.find(:all, :conditions => [ "country = ?",
params[:country] ] )
render :partial => 'states', :layout => false
end
My Partial Code: (To update the states combo box div)
------------------------------------------------------------------------------
<%= stylesheet_link_tag 'css_type1.css' %>
<p>
<label for="state">State </label>
<br/>
<%= select_tag(id= "user_state",
options_from_collection_for_select(@result,"state", "state")) %>
</p>
Thanks & Regards,
