Page saving error

Dobai-Pataky_BSSSSl · December 13, 2010, 10:02am

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.

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:
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.

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.

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]

ps. I apologize for my poor English.

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

best,

will

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.
