Can models be put in subfolders?

I’m looking for ways to make my project file hierarchy look a bit
neater, by joining what can be joined and removing what can be
removed. I know now how to put controllers into subfolders (see my
admin), but what about models?

Here’s what I got so far:

I’m looking for ways to make my project file hierarchy look a bit
neater, by joining what can be joined and removing what can be
removed. I know now how to put controllers into subfolders (see my
admin), but what about models?

I think you can add a sub directory to the load path, but I haven’t
done it, so this is untested. Put this in environment.rb.

config.load_paths += %W( #{RAILS_ROOT}/app/models/newdirectory )

Hope that helps.
Cheers,
Jordan

I have this line in my environments.rb file (within the initializer
block):

Dir.glob("#{RAILS_ROOT}/app/models/*[^(.rb|.ignore)]").each{|dir|
config.load_paths << dir }

So now I can organize models into subdirectories. And if there is a
subdir I don’t want loaded, I add “.ignore” to the end of it. Works
like a charm for me.

Danimal,
Would you mind using a few simple words to describe what is going on
with this (Dir.glob) you show below? What is the significance of
Dir.glob and how is it used? Could you throw in some comments to show
how this works?
How is Dir.glob then used in your application?
Thank you,
Kathleen

http://ruby-doc.org/core/classes/Dir.html#M002347

Maybe will help. Lists all the filenames under the specified directory.

That is truly awesome Danimal, much obliged!

Kathleen,

There could possibly be a cleaner way of doing this… i.e. grabbing
only the directories. The reason I used Dir.glob is two-fold:

  1. this was the example I found
  2. I can create a directory called “maybetoss.ignore” and put model
    files that I may be deleting but not sure.

It’s mostly just the way I work. As an application gets built out,
I’ll sometimes have models that I refactor or toss but I want to keep
the code around just in case.

So another way would be to use Dir.glob to get an array of everything
in app/models/ and then before adding it to the path, use
File.directory?(dir) to check if it’s a directory. The glob I have
just ignores “.rb” files.

So it’s really just a matter of how you want to arrange things in the
app/models/ directory. In my case, I only have .rb files, directories
and possibly a “something.ignore” directory, so that’s why I use the
glob I did.

Perhaps a cleaner one would be:

Dir.glob("#{RAILS_ROOT}/app/models/*").each{|dir| config.load_paths
<< dir if File.directory?(dir) }

This will then just add all subdirs to the load path.

Here’s my little contribution this problem, this add recursively all
subfolders :

Rails::Initializer.run do |config|
##…
def add_all_models_subfolders_recursively(config, path)
Dir.glob(path).each do |dir|
if File.directory?(dir)
p dir
config.load_paths << dir
add_all_models_subfolders_recursively(config, “#{dir}/")
end
end
end
add_all_models_subfolders_recursively(config, "#{RAILS_ROOT}/app/
models/
”)
##…
end

++

Hi,

I like Danimal’s approach.

Mine is recusive:

Dir.glob("#{RAILS_ROOT}/app/models/**/*").each {|d| config.load_paths
<< d if File.directory?(d) }

Kind regards
Peter

Kabnot,

That looks good to me… except that if I’m needing more than one
level of subfolders for my models, then either I’m over-organizing or
it is one big-ass project! The biggest Rails project I’ve done to date
only needed about 5-6 subfolders in the models directory. But, each to
their own. :slight_smile:

-Danimal

Hey Danimals and Pater ! :slight_smile:

Finally I’ve choose Peter’s solution, witch is concise and beautifull.
Mine is just strong-typing like and not in the ruby way :slight_smile:

Thanks.

Feels like, if you needed that many subfolders,
you should probably have been namespacing your models.

namely;

Users::Facebook, Users::Web
should live in /models/users

but, if we add all subfolders, we lose the possibility of this.
