In Radiant CMS when I’m trying to save any page that has any PageType  
but “normal” (Archive, Index,etc.) I get this error:

NoMethodError in Admin/pagesController#update

undefined method `[]’ for nil:NilClass

With clean Radiant everything’s work, my radiant carried with some  
extension, which may cause problem. Can anyone give me any clue how  
can I solve this problem? Thanks.

ps. I apologize for my poor English.

stack trace:

NoMethodError in Admin/pagesController#update

Are you running in development mode? If so, try opening  
config/environment.rb and changing this line:

```
config.time_zone = 'UTC'

```

To this:

```
config.active_record.default_timezone = :utc

```

There’s a persistent Activerecord bug:

> **[\#1339 AR::Base should not be nuking its children, just because it lost...](https://rails.lighthouseapp.com/projects/8994/tickets/1339)**

If you’re not in dev mode, or if that doesn’t solve it, you’ve got other  
problems. Let us know.

No, application is in production mode, though I tried to put the line  
in environment.rb file, but it didn’t help. Anyway thank you for  
answer.

It is an extension problem. It should be easy to find and you can  
probably eliminate it by changing the order in which the extensions  
load.

I think one of your extensions is calling  
Page.accepts\_nested\_attributes(:something) too late. Some Page  
subclasses have already been created, and they don’t get the call. When  
you try to save a page with one of those classes (ArchivePage, etc) it  
doesn’t know what to do with the nested attributes in the form. The  
error you see is due to an absence of nested\_attributes\_options.

First you need to work out which of your extensions is responsible.  
There are two ways to do that: either add some debugging lines to  
vendor/radiant/vendor/rails/  
activerecord/lib/active\_record/nested\_attributes.rb or (more easily),  
search through all the files in vendor/extensions looking for the string  
accepts\_nested\_attributes and see what stands out.

Then you need to make sure that troublesome extension loads before there  
is any inheritance from Page. To do that you uncomment this line in  
config/environment.rb:

# config.extensions = [:all]

and prepend the name of your extension:

config.extensions = [:something, :all]

Your English seems excellent to me. Please do say if anything here is  
unclear.

best,

Many thanks!! Your advice solved my problem. Page\_fields extension use  
that method. I’ve prepended it as you suggested, and now all work  
perfectly.
