Maaaaaaaaaaaaajor sanity check needed.  
I wrote a simple little plugin, and it wouldn’t load. I put some  
comments  
in it’s init.rb, and it didn’t even spit those out. So, I dug into the  
initializer.rb (/vendor/rails/railties/lib/initializer.rb) to see wtf is  
going on, and found the problem… but… can’t explain it. Here is the  
code in question:

```
    lib_path = File.join(directory, 'lib')
    init_path = File.join(directory, 'init.rb')
    has_lib = File.directory?(lib_path)
    #raise LoadError, "Dude, this path is ok: " + has_lib# =>

```

public/…/config/…/vendor/plugins/my\_plugin/init.rb  
has\_init = File.file?(init\_path)  
#raise LoadError, “WTF !..” + has\_init.to\_s# =\>  
False !!!

I’ve loaded the same situation up in IRB, and it works fine. Why is  
File.file?(init\_path) returning false !?  
Permissions are fine, the path is fine:  
public/…/config/…/vendor/plugins/my\_plugin/init.rb.

I’m losing my mind.

What version of rails are you running? Plugins don’t work before  
0.14releases…

So, I was able to hack this to work when I “hardcode” my absolute path  
in  
here… however, that is obviously the biggest hack ever.

Problem is, the path it’s getting from #{RAILS\_ROOT} is a relative path,  
and  
when it’s being applied within the context of the initializer.rb  
directory  
(which is actually in the /vendor/ directory), it’s not a valid URL  
anymore.

So, it looks as if you’re running Edge, and want plugins to work, your  
out  
of luck.  
Am I crazy ?

Dylan… don’t know if this will help you here or not, but I was  
commenting on the strange  
relative path that RAILS\_ROOT produces and Kris L. pointed out that  
one can do  
“File.expand\_path(RAILS\_ROOT)” to get the full path.

Thanks a bunch Ben. I just did a little test, and think I may have a  
possible bug in hand… but not sure.  
Here is what I did:

==============================

1. rails -v (rails 1.0.0)
2. rails test (in my home dir, now ive got  
/home/dylan/test/)
3. create plugin:  
(/home/dylan/test/vendor/plugins/custom/lib/custom.rb and

/home/dylan/test/vendor/plugins/custom/lib/init.rb)  
4) rake freeze\_edge

1. put debug in:  
(/home/dylan/test/vendor/rails/railties/lib/initializer.rb … line  
311:  
“raise LoadError, init\_path”)
2. output:  
“public/…/config/…/vendor/plugins/custom/init.rb”
3. put debug in:  
(/home/dylan/test/vendor/rails/railties/lib/initializer.rb … line  
312:  
“raise LoadError, has\_init.to\_s”)
4. output: “false”  
==============================

So, normal 1.0.0 install, froze edge, threw a valid plugin in  
/vendor/plugins, and initializer.rb can’t pick it up due to an invalid  
URL.

Do I have a point here, or am I doing something wrong ?
