ActionView::TemplateError (undefined method `any?' for nil:NilClass)

[xian7]

Summary: Clicking on "Sinppet Files" in a fresh new project results in a 500 "Application error."

Radiant Version: 1.1.3
Database: PostgreSQL 9.2
System: FreeBSD 8.3

Details:

1. Follow generic installation instructions to create a fresh radiant project using postgresql.
2. Setup the DB and confirm that it is working (I can run "script/console production" and call "Page.count" and get 0 as the result).
3. Start the server in production mode.
4. Login to the admin interface and navigate to the "Design" section.
5. Click on "Snippet Files".
6. Notice that you are now looking at a 500 error page.

Here is the exception from the production log file:

ActionView::TemplateError (undefined method `any?' for nil:NilClass) on line #12 of /usr/local/lib/ruby/gems/1.8/gems/radiant-snippets-extension-1.1.1/app/views/admin/snippet_files/index.html.haml:

Thoughts: So, yeah... @snippet_files is nil when it is probably expected to be an empty enumeration.

thanks for reporting this!

I have the same error. production.log says:

I just pushed up a new gem which should fix this: bundle update radiant-snippets-extension

[Linutux]

Thanks for fixing it so quick!

I did "bundle update" but now I can't start it:

Config definition error: 'defaults.snippet.filter' is defined twice:
1. /usr/local/rvm/gems/ruby-1.9.3-p448@meine-domain/gems/radiant-snippets-extension-1.1.2/config/initializers/radiant_config.rb:2:in `block in <top (required)>'

What did I wrong?

[jomz]

You did nothing wrong. I removed that config setting from radiant core on the master branch because it did not belong there. We should probably backport that and release 1.1.4

[jomz]

I just merged the commit that removes this config entry from core into the 1.1.3 branch;
2049684

[Linutux]

@jomz
Did you also update the gem on rubygems?

[jomz]

No, not yet, there's a failing spec I'd like to fix first.
I'll try to release today.

[jomz]

Fixed and pushed. @saturnflyer could you build and release 1.1.4? This issue can be closed then.

[jomz]

@saturnflyer scrap that, Travis failed on the 1.x branch, investigating.

[saturnflyer]

While we get radiant fixed up and the specs running for a new release, I pushed up a new version of radiant-snippets-extension.
Update your Gemfile to use version 1.1.3 and you should be ok.
