Tweet embed template tag
Takes a tweet url, requests the json from Twitter oEmbed, parses the json for the html element and returns it to your template. The html returned is ready to go and will be shown as a tweet on your web page. This uses the Requests library for Python. A full example can be found on GitHub https://github.com/z3ke1r/django-tweet-embed.

TemplateTag to call a method / function WITH arguments
**Callmethod** - TemplateTag to call a method on an object with arguments from within a template {% callmethod hotel.room_price_for_night night_date="2018-01-02" room_type=room_type_context_var %} ## equals ## >>> hotel.room_price_for_night(night_date="2018-01-02", room_type="standard") #Assuming "standard" is the value of room_type_context_var Django doesn't allow calling a method with arguments in the template to ensure good separation of design and code logic. However, sometimes you will be in situations where it is more maintainable to pass an argument to a method in the template than build an iterable (with the values already resolved) in a view. Furthermore, Django doesn't strictly follow its own ideology: the {% url "url:scheme" arg, kwarg=var %} templatetag readily accepts variables as parameters!! This template tag allows you to call a method on an object, with the specified arguments. Usage: {% callmethod object_var.method_name "arg1_is_a_string" arg2_is_a_var kwarg1="a string" kwarg2=another_contect_variable %} e.g. {% callmethod hotel.room_price_for_night date="2018-01-02" room_type="standard" %} {% callmethod hotel.get_booking_tsandcs "standard" %} NB: If for whatever reason you've ended up with a template context variable with the same name as the method you want to call on your object, you will need to force the template tag to regard that method as a string by putting it in quotes: {# Ensure we call hotel.room_price_for_night() even though there's a template var called {{ room_price_for_night }}! #} {% callmethod hotel."room_price_for_night" date="2018-01-02" room_type="standard" %} * **@author:** Dr Michael J T Brooks * **@version:** 2018-01-05 * **@copyright:** Onley Group 2018 (Onley Technical Consulting Ltd) [http://www.onleygroup.com](http://www.onleygroup.com) * **@license:** MIT (use as you wish, AS IS, no warranty on performance, no liability for losses, please retain the notice) * **@write_code_GET_PAID:** Want to work from home as a Django developer?

Recursive template tag for Django with arguments
This template tag was inspired by http://djangosnippets.org/snippets/592/, but with improvements in the syntax it is used with to be more function-like, and avoiding the problem of conditional recursion as noted in http://djangosnippets.org/comments/cr/15/592/#c2472. The syntax for using it can be seen in the docstring of the defrecurse() function. Additionally, a magic "level" variable is used to indicate the level of recursion, starting with 0 for the outermost level. This should theoretically allow for nested recursion, but the inner {% recurse %} call cannot call the outer {% defrecurse %} block.
