     2TemplateResponse and SimpleTemplateResponse
     3===========================================
     4
     5.. versionadded:: 1.3
     6
     7.. module:: django.template.response
     8   :synopsis: Classes dealing with lazy-rendered HTTP responses.
     9
     10Standard HttpResponse objects are static structures. They are provided
     11with a block of pre-rendered content at time of construction, and
     12while that content can be modified, it isn't in a form that makes it
     13easy to perform modifications.
     14
     15However, it can sometimes be beneficial to allow decorators or
     16middleware to modify a response *after* it has been constructed by the
     17view. For example, you may want to change the template that is used,
     18or put additional data into the context.
     19
     20TemplateResponse provides a way to do just that. Unlike basic
     21HttpResponse objects, TemplateResponse objects retain the details of
     22the template and context that was provided by the view to compute the
     23response. The final output of the response is not computed until
     24it is needed.
     25
     26TemplateResponse objects
     27========================
     28
     29.. class:: SimpleTemplateResponse()
     30
     31Attributes
     32----------
     33
     34.. attribute:: SimpleTemplateResponse.template_name
     35
     36    The name of the template to be rendered. Accepts
     37    :class:`django.template.Template` object, path to template or list
     38    of paths.
     39
     40    Example: ``['foo.html', 'path/to/bar.html']``
     41
     42.. attribute:: SimpleTemplateResponse.context_data
     43
     44    The context data to be used when rendering the template. It can be
     45    a dictionary or a context object.
     46
     47    Example: ``{'foo': 123}``
     48
     49
     50Methods
     51-------
     52
     53.. method:: SimpleTemplateResponse.__init__(template, context=None, mimetype=None, status=None, content_type=None)
     54
     55    Instantiates an
     56    :class:`~django.template.response.SimpleTemplateResponse` object
     57    with the given template, context, MIME type and HTTP status.
     58
     59    ``template`` is a full name of a template, or a sequence of
     60    template names. :class:`django.template.Template` instances can also be used.
     61
     62    ``context`` is a dictionary of values to add to the template context.
     63    By default, this is an empty dictionary. :class:`~django.template.Context` objects are also
     64    accepted as ``context`` values.
     65
     66    ``status`` is the HTTP Status code for the response.
     67
     68    ``content_type`` is an alias for ``mimetype``. Historically, this parameter
     69    was only called ``mimetype``, but since this is actually the value included
     70    in the HTTP ``Content-Type`` header, it can also include the character set
     71    encoding, which makes it more than just a MIME type specification.
     72    If ``mimetype`` is specified (not ``None``), that value is used.
     73    Otherwise, ``content_type`` is used. If neither is given, the
     74    ``DEFAULT_CONTENT_TYPE`` setting is used.
     75
     76
     77.. method:: SimpleTemplateResponse.resolve_context(context)
     78
     79    Converts context data into a context instance that can be used for
     80    rendering a template. Accepts a dictionary of context data or a
     81    context object. Returns a :class:`~django.template.Context`
     82    instance containing the provided data.
     83
     84    Override this method in order to customize context instantiation.
     85
     86.. method:: SimpleTemplateResponse.resolve_template(template)
     87
     88    Resolves the template instance to use for rendering. Accepts a
     89    path of a template to use, or a sequence of template paths.
     90    :class:`~django.template.Template` instances may also be provided.
     91    Returns the :class:`~django.template.Template` instance to be
     92    rendered.
     93
     94    Override this method in order to customize template rendering.
     95
     96.. method:: SimpleTemplateResponse.render():
     97
     98    Renders a template instance returned by
     99    :meth:`SimpleTemplateResponse.resolve_template` using the context instance
     100    returned by :meth:`SimpleTemplateResponse.resolve_context` and returns the
     101    rendered content.
     102
     103.. method:: SimpleTemplateResponse.bake():
     104
     105    Bakes the response by setting :attr:`response.content` to the result
     106    returned by :meth:`SimpleTemplateResponse.render`.
     107
     108    The response is baked by Django during response middleware cycle. You should
     109    only bake the response yourself if it is to be used outside the
     110    request-response cycle (e.g. for debugging). It will be baked twice
     111    otherwise.
     112
     113
     114.. class:: TemplateResponse()
     115
     116   TemplateResponse is a subclass of
     117   :class:`SimpleTemplateResponse <django.template.response.SimpleTemplateResponse>`
     118   that uses RequestContext instead of Context.
     119
     120.. method:: TemplateResponse.__init__(request, template, context=None, mimetype=None, status=None, content_type=None)
     121
     122   Instantiates an ``TemplateResponse`` object with the given template,
     123   context, MIME type and HTTP status.
     124
     125   ``request`` is a HttpRequest instance.
     126
     127   ``template`` is a full name of a template to use or sequence of
     128   template names. :class:`django.template.Template` instances are also
     129   accepted.
     130
     131   ``context`` is a dictionary of values to add to the template context.
     132   By default, this is an empty dictionary; context objects are also accepted
     133   as ``context`` values.
     134
     135   ``status`` is the HTTP Status code for the response.
     136
     137   ``content_type`` is an alias for ``mimetype``. Historically, this parameter
     138   was only called ``mimetype``, but since this is actually the value included
     139   in the HTTP ``Content-Type`` header, it can also include the character set
     140   encoding, which makes it more than just a MIME type specification.
     141   If ``mimetype`` is specified (not ``None``), that value is used.
     142   Otherwise, ``content_type`` is used. If neither is given, the
     143   ``DEFAULT_CONTENT_TYPE`` setting is used.
     144
     145
     146Baking
     147======
     148
     149*Baking* is the process by which the content in a TemplateResponse is
     150converted into the final form that will be returned to the client.
     151
     152There are three circumstances under which a TemplateResponse is baked:
     153
     154    * When the TemplateResponse instance is explicitly baked, using
     155      the :meth:`bake()` method.
     156
     157    * When the content of the response is explicitly set by assigning
     158      :attr:`response.content`.
     159
     160    * After passing through template response middleware, but before
     161      passing through response middleware.
     162
     163A TemplateResponse can only be baked once. The first call to
     164:meth:`bake()` sets the content of the response; subsequent baking
     165calls do not change the response content.
     166
     167However, when :attr:`response.content` is explicitly assigned, the
     168change is always applied. If you want to force templated content to be
     169rebaked, you can re-render the content and assign it::
     170
     171    # Set up a baked TemplateResponse
     172    >>> t = TemplateResponse(request, 'original.html', {})
     173    >>> t.bake()
     174    >>> print t.content
     175    Original content
     176
     177    # Rebaking doesn't change content
     178    >>> t.template_name = 'other.html'
     179    >>> t.bake()
     180    >>> print t.content
     181    Original content
     182
     183    # Assigning content does change
     184    >>> t.content = t.render()
     185    >>> print t.content
     186    Other content
     187
     188Using TemplateResponse and SimpleTemplateResponse
     189=================================================
     190
     191A TemplateResponse object can be used anywhere that a normal
     192HttpResponse can be used. It can also be used as an alternative to
     193calling render_to_response().
     194
     195For example, the following simple view returns a TemplateResponse
     196with a simple template, and a context containing a queryset::
     197
     198    from django.template.response import TemplateResponse
     199
     200    def blog_index(request):
     201        return TemplateResponse(request, 'entry_list.html', {'entries': Entry.objects.all()})

    120120classes are applied in reverse order, from the bottom up. This means classes
    121121defined at the end of :setting:`MIDDLEWARE_CLASSES` will be run first.
    122122
     123.. _template-response-middleware:
     124
     125``process_template_response``
     126-----------------------------
     127
     128.. versionadded:: 1.3
     129
     130.. method:: process_template_response(self, request, response)
     131
     132``request`` is an :class:`~django.http.HttpRequest` object. ``response`` is the
     133:class:`~django.template.response.SimpleTemplateResponse` subclass (e.g.
     134:class:`~django.template.response.TemplateResponse`) object returned by a
     135Django view.
     136
     137``process_template_response()`` must return an
     138:class:`~django.template.response.SimpleTemplateResponse` (or it's subclass)
     139object. It could alter the given ``response`` by changing
     140``response.template_name`` and ``response.template_context``, or it could
     141create and return a brand-new
     142:class:`~django.template.response.SimpleTemplateResponse` (or it's subclass)
     143instance.
     144
     145``process_template_response()`` is only called on response instances that
     146can be baked. It is called before the ``process_response()`` method.
     147
     148You don't need to explicitly bake responses -- responses will be automatically baked
     149once all template response middleware has been called.
     150
     151Middleware are run in reverse order during the response phase, which
     152includes process_template_response.
     153
    123154.. _exception-middleware:

    … …  
    137168the browser. Otherwise, default exception handling kicks in.
    138169
    139170Again, middleware are run in reverse order during the response phase, which
    140 includes ``process_exception``. If an exception middleware return a response,
     171includes ``process_exception``. If an exception middleware returns a response,
    141172the middleware classes above that middleware will not be called at all.

    1414
     15``render``
     16==========
     17
     18.. function:: render(request, template[, dictionary][, context_instance][, mimetype])
     19
     20   Combines a given template with a given context dictionary and returns an
     21   :class:`~django.http.HttpResponse` object with that rendered text.
     22
     23   :func:`render()` is the same as a call to
     24   :func:`render_to_response()` with a context_instance argument that
     25   that forces the use of a :class:`RequestContext`.
     26
     27Required arguments
     28------------------
     29
     30``request``
     31    The request object used to generate this response.
     32
     33``template``
     34    The full name of a template to use or sequence of template names.
     35
     36Optional arguments
     37------------------
     38
     39``dictionary``
     40    A dictionary of values to add to the template context. By default, this
     41    is an empty dictionary. If a value in the dictionary is callable, the
     42    view will call it just before rendering the template.
     43
     44``context_instance``
     45    The context instance to render the template with. By default, the template
     46    will be rendered with a ``RequestContext`` instance (filled with values from
     47    ``request`` and ```dictionary``).
     48
     49``mimetype``
     50    The MIME type to use for the resulting document. Defaults to the value of
     51    the :setting:`DEFAULT_CONTENT_TYPE` setting.
     52
     53Example
     54-------
     55
     56The following example renders the template ``myapp/index.html`` with the
     57MIME type ``application/xhtml+xml``::
     58
     59    from django.shortcuts import render_to_response
     60
     61    def my_view(request):
     62        # View code here...
     63        return render_to_response('myapp/index.html', {"foo": "bar"},
     64            mimetype="application/xhtml+xml")
     65
     66This example is equivalent to::
     67
     68    from django.http import HttpResponse
     69    from django.template import Context, loader
     70
     71    def my_view(request):
     72        # View code here...
     73        t = loader.get_template('myapp/template.html')
     74        c = RequestContext(request, {'foo': 'bar'})
     75        return HttpResponse(t.render(c),
     76            mimetype="application/xhtml+xml")
