"Partial Templates" - an alternative to "include"

This snippet adds simple partial support to your templates. You can pass data to the partial, and use it as you would in a regular template. It is different from Django's `{% include %}`, because it allows you to pass a custom variable (context), instead of reusing the same context for the included template. This decouples the templates from each other and allows for their greater reuse. The attached code needs to go into `templatetags` folder underneath your project. The usage is pretty simple - `{% load ... %}` the tag library, and use `{% partial_template template-name data %}` in your template. This will result in template passed as **template-name** to be loaded from **partials** folder. The **.html** extension will be appended to the file name. The file has to be in one of template paths accessible to the loader) and rendered with **data** as its context. The data is available in the template as an `item` context variable. You can find more information in the [relevant Django documentation](http://docs.djangoproject.com/en/dev/howto/custom-template-tags/#howto-custom-template-tags)

Paginator Tag

Piggybacks on the pagination-related template context variables provided by the `object_list` generic view, adding extra context variables for use in displaying links for a given number of pages adjacent to the current page and determining if the first and last pages are included in the displayed links. Also makes it easy to implement consistent paging all over your site by implementing your pagination controls in a single place - paginator.html. Optionally accepts a single argument to specify the number of page links adjacent to the current page to be displayed. Usage: `{% paginator %}` `{% paginator 5 %}`

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?

Template Tag Render Decorator

I often find myself needing to create a template tag and all I'm interested in is the token and the render function. This decorator abstracts away the boilerplate code around creating the template node class which is the same each and every time.

Tag that parses dict like format and convert to classes like AngularJS

This tag is inspired by how ng-class works in AngularJS. https://docs.angularjs.org/api/ng/directive/ngClass **example:** `context = { 'context_var': True, 'context_var_2': 'a' }` `{% classes "class_name_1": context_var == True, "class_name_2": context_var_2 == "a", "class_name_3": False %}` output: **class_name_1 class_name_2**

A templatetag to insert the output of another view (or local URL)

Inserts the output of a view, using fully qualified view name (and then some args), a or local Django URL. {% view view_or_url arg[ arg2] k=v [k2=v2...] %} This might be helpful if you are trying to do 'on-server' AJAX of page panels. Most browsers can call back to the server to get panels of content asynchonously, whilst others (such as mobiles that don't support AJAX very well) can have a template that embeds the output of the URL synchronously into the main page. Yay! Go the mobile web! Follow standard templatetag instructions for installing. **IMPORTANT**: the calling template must receive a context variable called 'request' containing the original HttpRequest. This means you should be OK with permissions and other session state. **ALSO NOTE**: that middleware is not invoked on this 'inner' view. Example usage... Using a view name (or something that evaluates to a view name): {% view "mymodule.views.inner" "value" %} {% view "mymodule.views.inner" keyword="value" %} {% view "mymodule.views.inner" arg_expr %} {% view "mymodule.views.inner" keyword=arg_expr %} {% view view_expr "value" %} {% view view_expr keyword="value" %} {% view view_expr arg_expr %} {% view view_expr keyword=arg_expr %} Using a URL (or something that evaluates to a URL): {% view "/inner" %} {% view url_expr %} (Note that every argument will be evaluated against context except for the names of any keyword arguments. If you're warped enough to need evaluated keyword names, then you're probably smart enough to add this yourself!)

Upgrade django url tags

In Django 1.5 url tags require you to pass in the name of the url as a string. So where you used to be able to do this {% url home_page %} you now have to do this {% url 'home_page' %} Upgrading an old project can be a pain, so here is a snippet for a py file that will update all your url tags. Just put it in a py file in your root directory and execute it. The error you get otherwise is: 'url' requires a non-empty first argument. The syntax changed in Django 1.5, see the docs.

Seconds-to-Duration Template Tag

Does exactly what it says on the tin! This template tag, when implemented, converts a duration (in seconds) to a more meaningful format. It has a short and long setting, which is easy to manipulate for your needs. Apologies if something already exists like this, however I felt that writing this would be quicker than trying to find it online. As an example, given the duration 84658: Short (default): 23 hrs 30 mins 58 secs Long: 23 hours, 30 minutes and 58 seconds All the best, [Dan Ward](http://d-w.me).

render_as_template template tag

This is a template tag that works like `{% include %}`, but instead of loading a template from a file, it uses some text from the current context, and renders that as though it were itself a template. This means, amongst other things, that you can use template tags and filters in database fields. For example, instead of: `{{ flatpage.content }}` you could use: `{% render_as_template flatpage.content %}` Then you can use template tags (such as `{% url showprofile user.id %}`) in flat pages, stored in the database. The template is rendered with the current context. Warning - only allow trusted users to edit content that gets rendered with this tag.

CallTag - Just like include, but can pass parameters to it

I knew that template in myght template system can receive some parameters just like a function. And I also want to implement this function in django template. So I finish a rough one, the code is pasted here. It just like include, but in order to distinguish with "include" tag, I call it "call". So you can use it: {% call "some.html" %} This way just like include tag, and the advanced way: {% call "some.html" with "a" "b"|capfirst title="title1" %} {% call "some.html" with "c" "d" title="title2" %} So you can see, "call" tag can do like a python function, it can receive tuple parameters and key word parameters, just like the function: def func(*args, **kwargs):pass How to use it =============== test_call.html {% expr "limodou" as name %} {% call "test/test_sub.html" with "a"|capfirst "b" title="title1" %}<br/> {% call "test/test_sub.html" with "c" "d" title="title2" %} expr is also a custom tag written by me. It'll calculate a python expression and save to result to a variable. In this case, the variable it "name". test_sub.html {% for i in args %}{{ i }}{% endfor %} <h2>{{ title }}</h2> <p>{{ name }}</p> <h3>args</h3> {{ args }} <h3>kwargs</h3> {{ kwargs }} And you also can see, call tag will auto create args and kwargs context variables. I hope this will be some useful.
