Hey there!
I have a dropdown list ready to go on my rails app. It calls my
action. My action works. Everythings good. Except I can''t figure out
for the life of me how to pass the value selected in the dropdown list
as a parameter to the action. I''ve discovered that forms are involved,
though no matter how many example I go through I can''t get them to
work. Here''s what I''ve got:
The dropdown list in the view:
<% form_tag({:controller => ''remote_site_controller'',
:action => ''filter''}) do %>
<%= text_field_tag(:search_options, params[:search_options])%>
<%= submit_tag("Display text!")%>
<% end -%>
<form id="filter_form" name="filter_form"
action="filter"
method="POST">
<td class="option">
<select name="filterlist[name]">
<option value="">Choose Filter Type
<% @filter_lists.each do |filterlist| %>
<option value="<%= filterlist.id %>"
<%= '' selected'' if filterlist.id ==
@filter_lists.id
%>>
<%= filterlist.name %>
</option>
<% end %>
</select>
<input style="font-size: 12pt; font-weight:bold"
type="submit"
value="Filter" />
</td>
</form>
And here''s my action:
def filter
type = params[:search_options]
render_text type
end
I''ve commented everything out of my action at the moment, and threw in
the render_text just to see what comes up. So far, for every attempt
I''ve made, render_text gives me nothing (leaving me to assume that
type is empty and not receiving the parameter). If you couldn''t tell,
I''ve never used a form before so I''m running around in the
dark, for
the most part. If anyone could drop me a hint I''d greatly appreciate
it, thanks.
Brad

I think I''ve almost got it. So I rearranged everything like this...
<% form_tag({:action => ''filter''}) do %>
<%= text_field_tag(:search_options, params[:search_options])%>
<%= submit_tag("Display text!")%>
<td class="option">
<select name="filterlist[name]">
<option value="">Choose Filter Type
<% @filter_lists.each do |filterlist| %>
<option value="<%= filterlist.id %>"
<%= '' selected'' if filterlist.id ==
@filter_lists.id
%>>
<%= filterlist.name %>
</option>
<% end %>
</select>
<input style="font-size: 12pt; font-weight:bold"
type="submit"
value="Filter" />
<% end -%>
But the dropdown didn''t show up. So instead I put everything outside
the <% end -%>:
<% form_tag({:action => ''filter''}) do %>
<%= text_field_tag(:search_options, params[:search_options])%>
<%= submit_tag("Display text!")%>
<% end -%>
<td class="option">
<select name="filterlist[name]">
<option value="">Choose Filter Type
<% @filter_lists.each do |filterlist| %>
<option value="<%= filterlist.id %>"
<%= '' selected'' if filterlist.id ==
@filter_lists.id
%>>
<%= filterlist.name %>
</option>
<% end %>
</select>
<input style="font-size: 12pt; font-weight:bold"
type="submit"
value="Filter" />
And when I click the button, nothing happens. So somehow my action
isn''t being called... Or the button/dropdown isn''t included in
the
form.

Or the button/dropdown isn''t included in the > form.The button is outside the form (assuming you''re talking about the Filter button rather than the ''Display text'' one), therefore clicking it does not submit the form. It probably doesn''t help that your html is completely malformed (which is probably why the first version didn''t work). In no particular orcer you''ve got a <td> which you never close (which sort of implies that the form above is at the top level of the form, which is also not allowed). You don''t close your option tags. The w3c html validator should be able to help you there (and I''d encourage you to read up on at least some basic html as you seem to be flailing around in the dark). You might save yourself some grief by using the rails helpers to generate your select box.

Gross. Alright, last try... is there anyway to pass the parameter (the
selected value in the dropdown list) to the controller just by using
this form? :
<form id="filter_form" name="filter_form"
action="filter"
method="POST">
<td class="option">
<select name="filterlist[name]">
<option value="">Choose Filter Type
<% @filter_lists.each do |filterlist| %>
<option value="<%= filterlist.id %>"
<%= '' selected'' if filterlist.id ==
@filter_lists.id
%>>
<%= filterlist.name %>
</option>
</option>
<% end %>
</select>
<input style="font-size: 12pt; font-weight:bold"
type="submit"
value="Filter" />
</td>
</form>
If not I''ll start googling on how to do the select box with the rails
helpers.

The <tr> and </tr> aren''t contained in the fragment I pasted, but they''re there, don''t worry. This code works, I''ve tested it. I just don''t know if its possible to pass a parameter with it. In the controller I''ve tried @type = params[:filter_form] and @type = params["filter_form"] but neither works. I''ve tested enough to know the action is being called. Every example I''ve seen (containing forms) passes a parameter with a rails form, which leads me to believe I need to use one, and not the html form I''ve pasted above, to pass the value. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

This code works, I''ve tested it."tested" how? You''ve already said it doesn''t work. When it passes the W3C validator, it "works". Yours won''t. Most egregiously, your option tags are *nested* which is totally wrong. And this: @type = params["filter_form"] :: doesn''t remotely match the parameter you''ve named here: <select name="filterlist[name]"> :: so I''m not sure what you''d expect to happen. BTW, if you change your form method to "GET" you can see the parameters in your browser''s address bar -- might speed things up...

You can see all the parameters passed in development.log (or stick a breakpoint in your action) rather than trying to guess what might be there.

The webpage works fine. I host is locally and open it in a web browser. Presto, it pops up, dropdown, button and all. The only thing that doesn''t work is passing the parameter. So if I have <select name="filterlist[name]"> then the name of the parameter is filterlist[name]? So then in my controller I should do something like: @type = params["filterlist[name]"] (I was using "filter_form" because thats the id of the form. Got to identify it somehow, I thought that was how you did it) Thanks for the tip with the "GET" method. Tried that, the correct parameter showed up in the address bar, so I know its there. Just need to nab it. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
