so i have this piece of code here  
`
Dir.glob(RAILS_ROOT + ‘/app/models//*.rb’).each do |file|
@models.push file.gsub(%r{ ^#{RAILS_ROOT + ‘/app/models/’}(.) }io,
‘\1’).chomp(’.rb’)
end
`

that gives me an array of all my models… its something i tweaked from  
the current examples on getting recursive directory listings…  
except, it doesnt seem very rubyish… and doesnt return what I really  
want…

what i want is some kind of way to have all my models and their  
associated namespaces in some kinda hash or array or something that i  
can use to refer to them in an administrationy menu…

no, i don’t like hobo or autoadmin or streamlined and don’t need all  
of their extended functionality…

and active scaffold doesn’t play well with rails 2.1.0…

thanks,

- FJM

Don’t know about the namespaces bit, but this will get a list of all  
your models:

are loaded…

class ListFiles

def initialize path

```
@dirs = []

@files = []

@platform = "/"

@platform = "\\" if PLATFORM =~ /win/

@root_path = os_path path

root = Dir.open(@root_path)

scan root

```

end

def list\_files

```
recurse

@files

```

end

def recurse

```
while @dirs != []

  path = @dirs.pop

  dir = Dir.open(path)

  scan dir

end

```

end

def scan dir

```
local_path = dir.path

dir.each do |item|

  path = os_join local_path, item

  (File.directory?(path) ? @dirs.push(path) : @files.push(path))

```

unless item.find {|r| r=~/^./ }

```
end

```

end

def os\_join \*args

```
args.join(@platform)

```

end

def os\_path path

```
if path.include?("\\")

  p = path.split("\\")

elsif path.include?("/")

  p = path.split("/")

end

path = os_join p

path

```

end

end

you use it like:

f = ListFiles.new(‘./app/models/’)  
f.list\_files

and will return an array of files in that directory with paths. it  
will ignore .name files (svn git…)

It is one of our home scripts, not very beautifull, but works.
