+ Django to Jinja
+ ~~~~~~~~~~~~~~~
+
+ Helper module that can convert django templates into Jinja2 templates.
+
+ This file is not intended to be used as stand alone application but to
+ be used as library. To convert templates you basically create your own
+ writer, add extra conversion logic for your custom template tags,
+ configure your django environment and run the `convert_templates`
+ function.
+
+ Here a simple example::
+
+ # configure django (or use settings.configure)
+ import os
+ os.environ['DJANGO_SETTINGS_MODULE'] = 'yourapplication.settings'
+ from yourapplication.foo.templatetags.bar import MyNode
+
+ from django2jinja import Writer, convert_templates
+
+ def write_my_node(writer, node):
+ writer.start_variable()
+ writer.write('myfunc(')
+ for idx, arg in enumerate(node.args):
+ if idx:
+ writer.write(', ')
+ writer.node(arg)
+ writer.write(')')
+ writer.end_variable()
+
+ writer = Writer()
+ writer.node_handlers[MyNode] = write_my_node
+ convert_templates('/path/to/output/folder', writer=writer)
+
+ Here is an example hos to automatically translate your django
+ variables to ambari_jinja2::
+
+ import re
+ # List of tuple (Match pattern, Replace pattern, Exclusion pattern)
+
+ var_re = ((re.compile(r"(u|user)\.is_authenticated"), r"\1.is_authenticated()", None),
+ (re.compile(r"\.non_field_errors"), r".non_field_errors()", None),
+ (re.compile(r"\.label_tag"), r".label_tag()", None),
+ (re.compile(r"\.as_dl"), r".as_dl()", None),
+ (re.compile(r"\.as_table"), r".as_table()", None),
+ (re.compile(r"\.as_widget"), r".as_widget()", None),
+ (re.compile(r"\.as_hidden"), r".as_hidden()", None),
+
+ (re.compile(r"\.get_([0-9_\w]+)_url"), r".get_\1_url()", None),
+ (re.compile(r"\.url"), r".url()", re.compile(r"(form|calendar).url")),
+ (re.compile(r"\.get_([0-9_\w]+)_display"), r".get_\1_display()", None),
+ (re.compile(r"loop\.counter"), r"loop.index", None),
+ (re.compile(r"loop\.revcounter"), r"loop.revindex", None),
+ (re.compile(r"request\.GET\.([0-9_\w]+)"), r"request.GET.get('\1', '')", None),
+ (re.compile(r"request\.get_host"), r"request.get_host()", None),
+
+ (re.compile(r"\.all(?!_)"), r".all()", None),
+ (re.compile(r"\.all\.0"), r".all()[0]", None),
+ (re.compile(r"\.([0-9])($|\s+)"), r"[\1]\2", None),
+ (re.compile(r"\.items"), r".items()", None),
+ )
+ writer = Writer(var_re=var_re)
