Hi,
I''m writing a form where the user should enter their date of birth.
Here''s the code:
<% form_for :applicant, :url=> {:action => "index"} do |f|
%>
...
<%= f.label :dob, "Date of Birth" %>
<%= f.date_select :dob, :include_blank => true %>
..
<p><%= submit_tag "Submit" %></p>
<% end %>
When I open the form in my browser everything is fine.
However when I select "February" as the month, "31" as the
day, don''t
select a year, and then press "Submit" I get the following error
message:
1 error(s) on assignment of multiparameter attributes
Can anyone tell me why this is happening and how to avoid this?
Thanks in advance.

Thanks for the quick reply. It is important for my form that the date_select helper is not initialized with a value (ie. :include_blank => true). So, how could I stop the above error from happening? Could you give me a hint as to which direction to be thinking in? I''m still relatively new to Rails, so I would be grateful if any explination isn''t too complicated. Thanks once again. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Nonetheless, two further questions: How does one rescue exceptons in rails? I just need a point to start. Would it be a feasible option to use three text fields in the form that are unrelated to the model. Then in the controller string them together and make a date object? (that would be more or less how I would do it in PHP). -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

You''d still have to rescue the exception that is raised by Date::civil when you pass it 2009,2,29 (or do all the bounds checking yourself) Fred --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Just thought I''d let you know how things turned out. I have discarded the idea of using date_select as it is full of inconsistencies which in the worst case can cause the application to crash. Instead I created three seperate text fields (DD-MM-YYYY)and using virtual attributes in the model mapped them to the "dob" field in the db. Now everything works like it should do (at last). I am surprised that this has presented me with such a problem as entering one''s dob into a form is a very common occurence. Nonetheless thanks for your help Fred. You definitely pointed me in the right direction. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
