I have a form with contingent select boxes (the state is contingent on
the country selected, so when the country selected changes, the state
changes -- I am using the Carmen plugin for getting my state names and
country names together, but not the functionality I am interested in
achieving).
Everything works fine except I cannot figure out how to amend my code
such that:
A. When the form is first rendered the state select box is empty (even
if there is a country showing, and the user (what I am calling an
"Associate" in terms of the model) HAS a state selected in his model.
-
and-
B.If I have, say, a state selected, I change the country, don''t select
a state for that country, then go back and select the original country
(for which I have a state selected) it still doesn''t display the
selected state -- just the list of states, unselected, in the state
select box (I believe the solution to #1, above, should solve this
too).
Ive scoured the net for examples of related matters, but cannot find
one similar to this. I am certain the solution must be little more
than a few lines of code which I am entirely oblivious to. Can someone
help me here? -JannaB
Here is the code I am using:
First, I have a model called Associates (for simplicity in
demonstration here, the only two members of Associates are state and
country, both Strings), and the /views/associates/_form.html.erb, as
follows:
<% form_for @associate do |f| %>
<%= f.error_messages %>
<p>
<%= f.label :city %><br />
<%= f.text_field :city %>
</p>
<p>
<%= f.label :state %><br />
<select id="state" name="state">
<option></option>
<%= render :partial => ''get_states'' %>
</select>
</p>
<p>
<%= f.label :country %><br />
<%= f.country_select :country, Carmen.default_country, {},
{
:onChange => remote_function( :url => { :action =>
''_get_states'' }, :update => "state", :with =>
"''country='' +value")
} %>
</p>
<p><%= f.submit "Submit" %></p>
<% end %>
"
Note that I have a partial that gets called, /views/associates/
_get_states.html.erb:
<% if @states !=nil %>
<% for state in @states %>
<option value="<%= state[1] %>"><%= state[0]
%></option>
<% end %>
<% end %>
Then, in my AssociatesController, I put in the method _get_states:
def _get_states
#essentially, this requires the 2 letter code for the country
selected, so if ''united_kingdom'' is selected
#it converts to UK and gets its "states". It also handles the default,
which is already specified properly
q = params[:country]
if(q!=Carmen.default_country)
q1 = q.gsub!("_", " ")
if(q1!=q && q1!=nil)
q = q1.titleize
else
q.capitalize!
end
q = Carmen::country_code(q)
end
@states = Carmen::states(q)
end

You never do this to you option tags and so your select box will never show the selected value. Why not use one of the rails helpers for generating option tags ? Fred
Fred, What do you mean "use one of the rails helpers for generating option tags?" Where can I see an example of this?
