Cache 404 responses or serve more static response?

Dobai-Pataky_BSSSSl · November 4, 2010, 7:29pm

Is there a way I can force Radiant to cache error responses?

Override this

            def virtual?
              true
            end

if you’re using nginx maybe you can use proxy_cache_valid. wouldn’t
nginx win out (at least if you had a page not found page)?

Hi,

I suddenly got this message on all my site pages today, can anyone
please explain what’s causing it?:

Ruby on Rails application could not be started

These are the possible causes:
There may be a syntax error in the application’s code. Please check for
such errors and fix them.
A required library may not installed. Please install all libraries that
this application requires.
The application may not be properly configured. Please check whether all
configuration files are written correctly, fix any incorrect
configurations, and restart this application.
A service that the application relies on (such as the database server or
the Ferret search engine server) may not have been started. Please start
that service.
Further information about the error may have been written to the
application’s log file. Please check it in order to analyse the problem.

looks like you need to install the custom_fields extension or track
down why it’s suddenly gone missing if you had it installed previously

Hi Guys,

For some reason I can no longer log into my Radiant admin Panel, when I
try I get the following message:

Application error

Change this error message for exceptions thrown outside of an action
(like in Dispatcher setups or broken Ruby code) in public/500.html

I have no idea what caused this and would appreciate any help. If there
is anymore info you need that would help you help me, then just ask.

Thanks

You’ll need to login to your server and get details from the log.

tail -900 log/production.log

for the last 900 lines in the log (don’t post them all here, please)
Or “tail -400”, “tail -999999”, etc

Have you looked in your error log(s)? That will tell you more than any

You need more than 20. Look through the errors to find something that
came from your application and that’s how you can start tracking it
down.
There might be a line in there similar to this:

/export/home/obi/radiant_app/vendor/extensions/something/something_extension.rb:13

That will point you to a file and a line number where the error
occurred. But you need to look further up the log. Try the last 200
lines.

ah, I see…

Could this section be the problem? Or should I look further up?

You got it!
It’s telling you that the application is looking in the database for a
table that isn’t there:

ActionView::TemplateError (PGError: ERROR: relation “custom_fields”

Do you need to migrate the database?

Ah, yes I remember being told to rake something in a set of
instructions, every-time I do though I get this message (hadn’t realized
the rake was so important so I just skipped it, oops):

rake aborted!
No Rakefile found (looking for: rakefile, Rakefile, rakefile.rb,
Rakefile.rb)
/usr/lib/ruby/gems/1.8/gems/rake-0.8.7/lib/rake.rb:2377:in
`raw_load_rakefile’
(See full trace by running task with --trace)

what could this mean? I’m pretty sure I already have rake installed

You get specific details right here.
It tells you the error (ActionView::TemplateError)
Then it tells you where
on line #1 of
vendor/extensions/stereotype/app/views/admin/_stereotype_td.html.haml:
And then shows you the actual code from that line
1: - stereotype = page.custom_fields.find(:first, :conditions =>
[“name = ?”, “stereotype”])

Okay, so your saying it’s the stereotype extension causing this
problem.

I guess the solution will either be figuring out how to do the rake or
figuring out how to uninstall the extension. For now it’s probably
better that I figure the rake out.

Any idea what causes the rake to abort?

Cheers

Hello Obi,

Are you running rake from the root of your radiant application? Rake is
installed globally but the tasks are defined locally, so the normal
sequence would be like this:

radiant /path/to/website
cd /path/to/website
rake db:migrate

… install some extensions, do something else…

cd /path/to/website
rake db:migrate:extensions

It must have worked once or your database wouldn’t be there at all.

best,

will

envygeeks · November 5, 2010, 3:51pm

Thank you Jim; Thanks Will.

Finally got everything sorted, just had to restart the server to see the
effect of the advice you guys gave me.
