    Comparison with Django Syntax

If you have read through the Django Tutorial, you've seen examples for templating in Django.  While the rest of Django, such as models, settings, migrations, etc., is the same (with or without DMP), the way you do templates will obviously change with DMP.  The following examples should help you understand the different between standard Django and DMP template syntax.
Note in the examples how the DMP column normally uses standard Python syntax, with no extra language to learn:

Output the value of the question variable:


    Django Templates
    DMP (Mako) Templates
  

    {{ question }}
    ${ question }
  

- Output a user's full name (a method on User):

  
    Django Templates
    DMP (Mako) Templates
  

    {{ user.get_full_name }}
    ${ user.get_full_name() }
  

- Iterate through a relationship:

  
    Django Templates
    DMP (Mako) Templates
  

    <ul>
  {% for choice in question.choice_set.all %}
    <li>{{ choice.choice_text }}</li>
  {% endfor %}
</ul>
    <ul>
  %for choice in question.choice_set.all():
    <li>${ choice.choice_text }</li>
  %endfor
</ul>
  

- Set a variable:

  
    Django Templates
    DMP (Mako) Templates
  

    {% with name="Sam" %}
    <% name = "Sam" %>
  

- Format a date:

  
    Django Templates
    DMP (Mako) Templates
  

    {{ value|date:"D d M Y" }}
    ${ value.strftime('%D %d %M %Y') }
  

- Join a list:

  
    Django Templates
    DMP (Mako) Templates
  

    {{ mylist | join:', ' }}
    ${ ', '.join(mylist) }
  

- Use the /static prefix:

  
    Django Templates
    DMP (Mako) Templates
  

    {% load static %}
<img src="{% get_static_prefix %}images/hi.jpg"/>
    <img src="${ settings.STATIC_ROOT }images/hi.jpg"/>
  

- Call a Python method:

  
    Django Templates
    DMP (Mako) Templates
  

    Requires a custom tag, unless a built-in tag provides the behavior.
    Any Python method can be called:
<%! import random %>
${ random.randint(1, 10) }
  

- Output a default if empty:

  
    Django Templates
    DMP (Mako) Templates
  

    {{ value | default:"nothing" }}
    
      Use a boolean:
      ${ value or "nothing" }
      or use a Python if statement:
      ${ value if value != None else "nothing" }
    
  
- Run arbitrary Python (keep it simple, Tex!):

  
    Django Templates
    DMP (Mako) Templates
  

    Requires a custom tag
    <%
  i = 1
  while i < 10:
    context.write('<p>Testing {0}</p>'.format(i))
    i += 1
%>
  

- Inherit another template:

  
    Django Templates
    DMP (Mako) Templates
  

    {% extends "base.html" %}
    <%inherit file="base.htm" />
  

- Override a block:

  
    Django Templates
    DMP (Mako) Templates
  

    {% block title %}My amazing blog{% endblock %}
    <%block name="title">My amazing blog</%block>
  

- Link to a CSS file:

  
    Django Templates
    DMP (Mako) Templates
  

    Place in each template: <link rel="stylesheet" type="text/css" href="...">
    Simply name the .css/.js file the same name as your .html template.  DMP will include the link automatically.
  

- Perform per-request logic in CSS or JS files:

  
    Django Templates
    DMP (Mako) Templates
  

    Create an entry in ``urls.py``, create a view, and render a template for the CSS or JS.
    Simply name the .css file as name.cssm for each name.html template.  DMP will render the template and include it automatically.
