Hi,

I have been developing on the local box up until yesterday when I moved  
the dev environment to a common server. Everything works just fine  
except for one thing. Rails seems to be caching templates. I cannot  
edit a template and make the changes show up without having to bounce  
the server (mongrel or webrick, same story).  
I checked all the config files for the caching and it is turned off as  
far as i can tell. If I put something like raise hell in one of my  
controllers, the errors get thrown like usual. Seems like it is just  
affecting the templates.

#development.rb  
config.cache\_classes = false  
config.action\_controller.consider\_all\_requests\_local = true  
config.action\_controller.perform\_caching = false  
config.action\_view.cache\_template\_extensions = false  
config.action\_view.debug\_rjs = true

It’s not caching urls, just the templates. If I make the controller  
return less results or something similar, that shows up fine, but if I  
add something to the template, that will not.

If I move the template out of the way between requests, an error gets  
thrown, so it is looking for it.

Have not verified if it is persistant or the cache clears after a  
while.

Any ideas?

Thanks,  
Fredrik

It gets stranger. If I make a change to the ruby code in the template,  
the page breaks. If I undo my changes, the page is still broken. I’m  
it’s not strange at all once I figure out what is causing it.

Any ideas? I still can’t seem to figure out what’s going on and in  
order to get our dev environment on a common box where we all use the  
same configuration I really need to solve this.

Thanks guys.  
Fredrik

Well, in order to keep my blog up-to-date 🙂  
Here is what apparently happened, but I don’t know why just yet.  
The folder the application was sitting in was a mounted nfs share.  
I checked out the project into /tmp and fired up a mongrel and there it  
was without cache acting just like I wanted it too.

It looks like the cache expires at some point since when I came in this  
morning and made a change to a runnning app, it reflected the change,  
but when I made a second change it pulled the cached version again.

Anyone else running their apps from an nfs mount?

Thanks,  
Fredrik
