Hello,

Recently I am working on calendar on rails and found the Railendar  
[http://rubyforge.org/projects/railendar/](http://rubyforge.org/projects/railendar/)

When I was trying to run it, the display calendar works, but the  
admin/new function didn’t work, I got the error like

"  
ArgumentError in Admin#new

Showing app/views/admin/\_form.rhtml where line #11 raised:  
wrong number of arguments (0 for 1)  
Extracted source (around line #11):

8: \<%= text\_area ‘event’, ‘description’ %\>

  
9:  
10: 

Date  
11: \<%= date\_select ‘event’, ‘startdate’ %\>  
  
12: Start  
13: \<%= my\_time\_select ‘event’, ‘starttime’ %\>  
  
14: End

Trace of template inclusion: /app/views/admin/new.rhtml

RAILS\_ROOT: script/…/config/…  
Application Trace | Framework Trace | Full Trace

app/helpers/my\_date\_helper.rb:233:in `value' app/helpers/my_date_helper.rb:233:in `date\_or\_time\_select’  
app/helpers/my\_date\_helper.rb:217:in `to_date_select_tag' #{RAILS_ROOT}/app/views/admin/_form.rhtml:11:in `\_run\_rhtml\_47app47views47admin47\_form46rhtml’  
#{RAILS\_ROOT}/app/views/admin/new.rhtml:5:in  
`\_run\_rhtml\_47app47views47admin47new46rhtml’  
"

Basically I just follow the instruction and ran the original code, I  
searched a lot on internet and reinstalled several times and still got  
the same error. It seems somebody talked about the problem of  
date\_time\_select when upgrading to the newest rails. Much appreciate if  
anybody can give me some ideas on the problem. Thanks a lot!

Btw, my version is Ruby 1.8.2, rails 1.2.3, mysql 5.0, OSX 10.4.9,

Thanks!  
XJ

the same problem

there are some fixes on date\_he;per, please refer to  
[http://dev.rubyonrails.org/ticket/3811](http://dev.rubyonrails.org/ticket/3811), the last one  
date\_select\_regression.diff
