Install

Basic Install:

$ python setup.py build $ sudo python setup.py install

Alternative Install (Manually):

Place webutils directory in your Python path. Either in your Python installs site-packages directory or set your $PYTHONPATH environment variable to include a directory where the webutils directory lives.

You must create a “Config” object in your app and use that to fetch any object or value you want to be able to have customized.

Here is a basic example.

### yourapp/config.py

from easyconfig import EasyConfig
from django.contrib.auth.forms import AuthenticationForm
from yourapp.forms import PasswordChangeForm


class Config(object):
    ''' Base config class to easily pass forms, etc. to
        yourapp views.
    '''
    # Use the dotted Python path to this class
    config = EasyConfig('yourapp.config.Config', 'YOURAPP_CONFIG')

    def get_login_form(self):
        return self.config.get_object('get_login_form', AuthenticationForm)

    def get_password_change_form(self):
        return self.config.get_object('get_password_change_form', PasswordChangeForm)

Now, you just need to use your yourapp.Config class any time you need to fetch one of these objects for use.

Here’s how it could be used in a urls.py file

### urls.py

from django.conf.urls import url
from yourapp import views
from yourapp.config import Config


config = Config()

urlpatterns = [
    url(r'^login/$',
        views.login, {
            'template_name': 'yourapp/login.html',
            'authentication_form': config.get_login_form(),
        }, name='yourapp-login'),
    url(r'^passwd_change/$',
        views.passwd_change, {
            'template_name': 'yourapp/passwd_change.html',
            'passwd_change_form': config.get_password_change_form(),
        }, name='yourapp-passwd-change'),
]

Now, anybody using your app in their own project can easily change the login and password change forms to whatever form they want. Here is how they would do so in their own project.

### settings.py

# Dotted python path to their own CustomConfig class
YOURAPP_CONFIG = 'myproject.myapp.config.CustomConfig'

### myproject/myapp/config.py

from myproject.myapp.forms import AuthForm, ChangeForm


class CustomConfig(object):
    ''' Customize the forms!
    '''
    def get_login_form(self):
        return AuthForm

    def get_password_change_form(self):
        return ChangeForm

That’s it. Easy right? :)
