restrict user access to modeladmin via metaclass

* Include `__metaclass__ = user_lock` to your ModelAdmin class * Add `__target__ = path_to_user_field` somewhere in the ModelAdmin * done! `__target__` is what will be used in the `filter` call. examples `'user'` or `'author'` or `'message__user'` e.t.c. The result of `__target__` is the field that is then checked against `request.user`

currency filter without using locale

This snippet is a combination of the existing currency snippets I found and some modifications to use your own settings without the need to have the locale installed on the system. You can define in settings.py: DECIMAL_SEPARATOR = ',' THOUSAND_SEPARATOR = '.' CURRENCY_SYMBOL = u'€' With the above settings, using `{{ 1234.30|currency }}` on a template would result in `€1.234,30`

login_required decorator that doesn't redirect

A login_required decorator that wraps the login view instead of redirecting to it. This prevents your site from leaking login information with HTTP status codes as explained [here](https://grepular.com/Abusing_HTTP_Status_Codes_to_Expose_Private_Information). This is the way Django's admin is protected, the difference being that it checks for is_active and is_staff instead of is_authenticated. With this decorators, users directly see a login form (no redirect), post it to LOGIN_URL and are redirected to the page they first tried to see.

SQL Log Middleware - with multiple databases

This is an improvement of [joshua](http://djangosnippets.org/users/joshua/)'s [SQL Log Middleware](http://djangosnippets.org/snippets/61/). If you have more than one database connection, then all queries are logged, grouped by connection. If a connection has no queries, then it's not shown.

Class-Based AJAX fallback view

If you're used to auto_render like I am (and think it's an awesome way to DRY code) and you want to support users with and without javascript enabled, this class is perfect. You will need to provide the format requested, either through adding "(\.format)?" at the end of the url or through some middleware, but once you've done so this class will take care of rendering through the given template for normal users, JSON or JSONP for AJAX users. From [fahhem.com](http://fahhem.com/) and [Recrec Labs](http://recreclabs.com/)

View to retrieve objects meeting a complex tag query

This view parses complex tag queries. It generates a list of model instances matching an expression of tags. The expression currently supports intersection, union and subtraction. Expressions can also be put in parenthesis and then combined with other expressions. The expression must be passed to this view in the tag_expression argument. In my application this is simply passed from the URL querystring. This snippet uses the django-tagging app. It assumes that tags are composed of alphanumeric characters, underscores, hyphens and spaces, but the django-tagging application allows tags with other characters, so you might either want to restrict users to using tags that only contain the above characters, or you might prefer to improve this snippet. Example: This URL http://example.com/people/?(deceased&parrot)|"Monty Python" will retrieve all people who are either deceased parrots or members of Monty Python. In the tag_expression argument: * ALL is treated as a keyword. If you happen (by some sad chance) to have a tag called ALL and want to use it in the expression, surround it in quotation marks. E.g. "ALL" * Examples: - famous -returns all instances of the model tagged with famous - famous&deceased -returns all instances of the model tagged both famous and deceased. - famous|deceased -returns all instances of the model tagged famous or deceased. - parrot-deceased -returns all alive parrots in the model. - ALL-deceased -returns all instances of the model that are not tagged deceased. - ALL -returns all instances of the model - "ALL" -returns all instances of the model that are tagged ALL - "great author"&deceased -returns all models tagged as great authors and deceased. Arguments: * request -- HTTP Request object * tag_expression -- a set expression of tags, supporting intersection, union, parenthesis and difference * app_name -- App for the model we're working on (defaults to pubman) * model_name -- Model on which to apply the set operations (defaults to Article) * view -- view to redirect to after the model instance list has been constructed * html_template -- HTML template to redirect (defaults to 'pubman/tag.html')

notify admin what fields have changed in form submission

here is some working code from a site that maintains profile information (address, phone number, etc) for users ("Partners"). this snippet handles the submitted form (after validation) and checks to see if any fields have been changed by the partner. if so, it shoots off an email to the admin showing the current profile information with changed fields marked with asterisks.

Semi-Portable recaptcha integration with django forms

It is not so portable and easy as I wanted it to be because of how django forms work - they don't play well with recaptcha. To get it to work: * Add two variables to your app settings, **RECAPTCHA_PUBKEY** and **RECAPTCHA_PRIVKEY** * Derive forms you want to have a captcha from the provided `ReCaptchaForm` class (how to get it working with ModelForm? any ideas?) * * If you override the form's clean method make sure you firstly call the `ReCaptchaForm`'s clean method * * In your view, upon receiving the form data initialize the objects like this `form = YouFormClassDerivedFromReCaptchaForm(remoteip=request.META['REMOTE_ADDR'], data=request.POST)` (or request.GET of course) - this is because reCaptcha needs the user's remote ip.
