| 5 | == Templated Response class == |
| 6 | |
| 7 | This class cuts back on the standard calls to load the template, generate a stream and populate it with data and subsequently render it. The data parameter is best passed as a dict. |

| 9 | {{{ |
| 10 | #!python |
| 11 | from werkzeug import Response as BaseResponse |
| 12 | |
| 13 | TEMPLATES_DIR = # some path |
| 14 | |
| 15 | class Response(BaseResponse): |
| 16 | """Subclass of base responses that has a default mimetype of text/html.""" |
| 17 | default_mimetype = "text/html" |
| 18 | |
| 19 | class TemplatedResponse(Response): |
| 20 | """Response class with built in template renderer.""" |
| 21 | |
| 22 | loader = None |
| 23 | |
| 24 | def __init__(self, template, data): |
| 25 | if TemplatedResponse.loader is None: |
| 26 | TemplatedResponse.loader = TemplateLoader(TEMPLATES_DIR, auto_reload=True) |
| 27 | self.template = self.loader.load(template) |
| 28 | self.stream = self.template.generate(data=data) |
| 29 | self.response = self.stream.render('xhtml', doctype=DocType.XHTML_STRICT) |
| 30 | |
| 31 | Response.__init__(self, self.response) |

| 33 | |
| 34 | Within your code you can then import this class and do something like: |
| 35 | |
| 36 | {{{ |
| 37 | #!python |
| 38 | return TemplatedResponse(template='my_template.html', data={'name': some_variable}) |
| 39 | }}} |
