How do I pass parameters day, month and year using select_date?

Question

I have the following date_select, which displays three drop-down menus, from which I can select the month, day, and year.

<%=date_select("dateName", "dateMethod", :order => [:month, :day, :year])%>

I don't know how to pass the parameters to the next page. How can I pass the month, day and year with a submit_tag or a link_to? I am in a view page named generateDataForReport, and I want to catch the parameters in another view under the same controller named showGeneratedReport.

If you look at your console when you submit the form, you can see how these parameters are named:

"dateName"=>{"dateMethod(2i)"=>"12", "dateMethod(3i)"=>"1", "dateMethod(1i)"=>"2013"

In your controller, you can grab the parameters like this:

Year:

params[:dateName]['dateMethod(1i)']

Month:

params[:dateName]['dateMethod(2i)']

Day:

params[:dateName]['dateMethod(3i)']

You can assign them to variables in your controller to make them easier to deal with:

day = params[:dateName]['dateMethod(3i)']
month = params[:dateName]['dateMethod(2i)']
year = params[:dateName]['dateMethod(1i)']

If you want to pass these params to your next page, then do this in your redirect:

redirect_to report_path(@report, :d => day, :m => month, :y => year) 

Now on the next page, your URL should look something like this showing your params:

http://localhost:3000/reports/28?d=1&m=12&y=2013

Now to display them on the page you do this:

  <%= params[:d] %>
  <%= params[:m] %>
  <%= params[:y] %>
