Method to use subdirectories for the views

[parg-programador]

I created um method in my application for improve the organization of my views, I don't know if the code it's interesting for be used as internal resource of bottle library.

import bottle
from os import listdir
from os.path import dirname, realpath, join, isdir

def config_views_directory(all_subdirs=False):
    """ config the path of views """
    abs_app_dir_path = dirname(realpath(__file__))
    abs_views_path = join(abs_app_dir_path, 'views')
    index = 0

    # insert the path of views
    bottle.TEMPLATE_PATH.insert(index, abs_views_path)

    # verify the directory
    def process_directory(index, path):
        """ process the directory """
        for file_name in listdir(path):
            next_path = join(path, file_name)

            # verify the directory
            if isdir(next_path):
                index += 1

                # insert the path of views
                bottle.TEMPLATE_PATH.insert(index, next_path)

                # checks to process all subdirectories
                if all_subdirs:
                    index = process_directory(index, next_path)
        
        return index

    process_directory(index, abs_views_path)

One thing that I forgot comment it's that when I create new views files I take care to not create files with same names, even if they are in different subdirectories.

views
|----backend
----|----login.tpl
|----fronend
----|----front_login.tpl

@view('login')
def backend_login():
    pass

@view('front_login')
def frontend_login():
    pass
