NoMethodError

[Onno van der Straaten <onno.van.der.straaten@xxxxxxxxx>]

Hi Han Mei,
About EPF Wiki. I have not seen this error before. I'm assuming this is a new installation. I suggest you recreate the database or do the setup again. To recreate the database the steps are:

1. Empty folders public/bp and public/wikis
2. Start terminal and move into EPF Wiki app folder
3. run commands

1. export RAILS_ENV=production

2.  rake db:drop db:create db:migrate
4. Restart apache
5. Access EPF Wiki in browser to create the admin account

If the same problem occurs can you send me more details on the steps you take to do a update? Can you send me the log file log/production?
Best Regards,
Onno

I got two questions about epf

one is about epf composer.

how to customize "view" of a configuration ? i add some library myself, and i want to publish them, but I found that I can't adjust the structure of default view tree.

the other is about epf wiki rails application.

when i followed the epf wiki installation guide for ubuntu. and i got several errors.

(1) when i update the schedule by clicking the link "update now", and i got the rails error:

   NoMethodError

You have a nil object when you didn't expect it!
The error occurred while evaluating nil.title

(2) in the web "sites/description/3" , i clicked "upload", it turns out a rails error too.

   NoMethodError in #

Showing uploads/_list.rhtml where line #27 raised:

undefined method `length' for #<Enumerable::Enumerator:0xb5d16978>

hwo to resolve these two problem?
