Greetings. I have a route something like this:
map.calendar ''/tasks/:year/:month'',
:controller => ''tasks'',
:action => ''calendar'',
:year => /\d{4}/,
:month => /\d{2}/
(Ignore the obvious problems of invalid data.)
I''m trying to create a form that will allow my users to navigate from
one month/year to the next. Here''s my form:
<% form_tag(tasks_path, :method => :get) do %>
<%= select_month(Date.today, :prefix => ''month'',
:discard_type =>
true %>
<%= select_year(Date.today, :prefix => ''year'',
:discard_type => true
%>
<button>go</button>
<% end %>
If you submit this form, the request generates an URL like this: /
tasks?month=7&year=2008 sent to the #index method on TasksController.
Why isn''t this recognized as a request to the #calendar action? What
am I doing wrong?
James

So, when the request /tasks?year=2008&month=8 comes in, why doesn''t Rails recognize this as /tasks/2008/8?

James, At the risk of being rude, the problem is that you don''t understand how routing works. 1) map.calendar ... would give you a calendar_path(:year, :month) function, not task_path. If you have a task_path function, it is being generated from a different rule. 2) In the request /tasks?year=2008&month=8, everything after the question mark is just data generated from the form, and is invisible to the routing. 3) To get the routing you were trying for, you would need: <% form_tag(calendar_path(year, month), :method => :get) do %> The problem you have is that the form tag is evaluated when the form is generated, before it is sent to the browser. This means that the user data can''t be used this way. To do what you want to do, you will need a different algorithm. Probably you want a two stage approach. Have one action that evaluates the user data, and then redirects to the desired action. Hope that helps, --Will Merrell James Herdman wrote:> So, when the request /tasks?year=2008&month=8 comes in, why doesn''t > Rails recognize this as /tasks/2008/8? > > James > > On Fri, Jul 4, 2008 at 5:03 PM, Philip Hallstrom <philip-LSG90OXdqQE@public.gmane.org > <mailto:philip-LSG90OXdqQE@public.gmane.org>> wrote: > > > > Greetings.

Hi Will! No offence taken. My knowledge of the router had a gap and this is where it was at, hence the original message :) Thanks for the info. I''d prefer to avoid a two-stage solution, but I have a feeling there isn''t much of a way around it. Many thanks.
