Enhanced Django templates with Mako

Django Default template functionality is also possible, but not directly with the Python syntax, mako solve the pain point,
Makes Django templates look like JSPs and can do things directly using Python's syntax.

Mako
Django-mako
Demo

Mako Basic usageMako's template needs to be done this way.

A direct look like the Python string format
From mako.template Import Template
MyTemplate = Template ("Hello, ${name}!")
Print Mytemplate.render (name= "Jack")
With file
From mako.template Import Template
MyTemplate = Template (filename= '/docs/mytmpl.txt ', module_directory= '/tmp/mako_modules ')
Print Mytemplate.render ()
When you need to inherit or search for other template files, you need to templatelookup
From mako.template Import Template
From Mako.lookup import Templatelookup
Mylookup = Templatelookup (directories=['/docs ')
MyTemplate = Template ("" "<%include file=" header.txt "/> Hello world!" "",
Lookup=mylookup)

Feeling very complicated, the advent of Django-mako reduced these tedious things to 0, allowing Django to still use Render_to_response

After using Django-mako

A simple view

From djangomako.shortcuts Import render_to_responsedef Index (Request):    return Render_to_response (' index.html ', { })

Index.html

<%! Import OS%><%    rows = [[V for V in Range (0,10)] for row in range (0,10)]%><%def name= "Makerow (Row)" >
   
    <tr>    % for name in row:        <td>${name}</td>    % endfor    </tr></%def>< html>  <body>    ${os.path.sep}    <table>        % for row in rows:            ${makerow (Row)}        % ENDfor    </table>  </body>

This can be called because Django-mako has such a middleware, in the settings.py to join the middleware can easily use the MAKO syntax

From mako.lookup import Templatelookupimport tempfileclass Makomiddleware (object): Def __init__ (self): "" "Setup Mako variables and Lookup object "" "from django.conf Import settings # Set All Mako variables based on Djang o Settings Global template_dirs, output_encoding, module_directory, encoding_errors directories = GetAt TR (settings, ' Mako_template_dirs ', settings.  Template_dirs) Module_directory = getattr (settings, ' Mako_module_dir ', Tempfile.mkdtemp ()) output_encoding = GetAttr (settings, ' mako_output_encoding ', ' utf-8 ') encoding_errors = getattr (settings, ' mako_encoding_errors ', '                                Replace ') Global lookup lookup = Templatelookup (directories=directories,.                                Module_directory=module_directory, Output_encoding=output_encoding,.      Encoding_errors=encoding_errors,) Import Djangomako  Djangomako.lookup = Lookup

The syntax of Mako

An expression
${expression}: ${2*3}–> 6
${pow (x,2) + POW (y,2)}

Control

% for a in [' One ', ' one ', ' three ', ' four ', ' five ']:

% if a[0] = = ' t ': its-or three% elif a[0] = = ' F ': four/five% else:one% endif

% ENDfor

code block
<%! %> and <%%> are not the same, <%! %> is only loaded once, so it's like defining a method, import something, and write it in here.
<%!
```
Import Mylibimport redef Filter (text):    return re.sub (R ' ^@ ', ', text)
```
%>
<%
```
x = Db.get_resource (' foo ') y = [z.element for z in x if x.frobnizzle==5]
```
