TemplateResponse dan``SimpleTemplateResponse``Link to this heading#

\n

Standard HttpResponse objects are static structures.\nThey are provided with a block of pre-rendered content at time of\nconstruction, and while that content can be modified, it isn't in a form that\nmakes it easy to perform modifications.

\n

However, it can sometimes be beneficial to allow decorators or\nmiddleware to modify a response after it has been constructed by the\nview. For example, you may want to change the template that is used,\nor put additional data into the context.

\n

TemplateResponse provides a way to do just that. Unlike basic\nHttpResponse objects, TemplateResponse objects retain\nthe details of the template and context that was provided by the view to\ncompute the response. The final output of the response is not computed until\nit is needed, later in the response process.

\nSimpleTemplateResponse.resolve_context(context)Link to this definition#
\n

Preprocesses context data that will be used for rendering a template.\nAccepts a dict of context data. By default, returns the same\ndict.

\nSimpleTemplateResponse.resolve_template(template)Link to this definition#

\n\n
\n
\nSimpleTemplateResponse.add_post_render_callback()Link to this definition#
\n

Add a callback that will be invoked after rendering has taken\nplace. This hook can be used to defer certain processing\noperations (such as caching) until after rendering has occurred.

\n

Jika SimpleTemplateResponse sudah dibangun, callback akan dipanggil segera.

\n

Ketika dipanggil, callback akan melewatkan argumen tunggal -- instance SimpleTemplateResponse terbangun.

\n

If the callback returns a value that is not None, this will be\nused as the response instead of the original response object (and\nwill be passed to the next post rendering callback etc.)

\n
\n\n
\n
\nSimpleTemplateResponse.render()Link to this definition#
\n

Sets response.content to the result obtained by\nSimpleTemplateResponse.rendered_content, runs all post-rendering\ncallbacks, and returns the resulting response object.

\n

render() will only have an effect the first time it is called. On\nsubsequent calls, it will return the result obtained from the first call.

Pengolahan membangunLink to this heading#

\n

Before a TemplateResponse instance can be\nreturned to the client, it must be rendered. The rendering process takes the\nintermediate representation of template and context, and turns it into the\nfinal byte stream that can be served to the client.

\n

Ada tiga keadaan dibawah mana TemplateResponse akan dibangun:

\n\n

Sebuah TemplateResponse hanya dapat dibangun sekali. Panggilan pertama pada SimpleTemplateResponse.render() mensetel isi dari tanggapan; selanjutnya membangun panggilan untuk tidak merubah isi tanggapan.

\n

However, when response.content is explicitly assigned, the\nchange is always applied. If you want to force the content to be\nre-rendered, you can reevaluate the rendered content, and assign\nthe content of the response manually:

\n
Python console
# Set up a rendered TemplateResponse\n>>> from django.template.response import TemplateResponse\n>>> t = TemplateResponse(request, "original.html", {})\n>>> t.render()\n>>> print(t.content)\nOriginal content\n\n# Re-rendering doesn't change content\n>>> t.template_name = "new.html"\n>>> t.render()\n>>> print(t.content)\nOriginal content\n\n# Assigning content does change, no render() call required\n>>> t.content = t.rendered_content\n>>> print(t.content)\nNew content\n
\n
\n

Callback pasca-dibangunLink to this heading#

\n

Beberapa tindakan - seperti menyimpan sementara - tidak dapat dilakukan pada cetakan yang belum dibangun. Mereka harus dilakukan pada sepenuhnya lengkap dan tanggapan yang dibangun.

\n

If you're using middleware, you can do that. Middleware provides\nmultiple opportunities to process a response on exit from a view. If\nyou put behavior in the response middleware, it's guaranteed to execute\nafter template rendering has taken place.

\n

Bagaimanapun, jika anda sedang menggunakan penghias, kesempatan sama tidak ada. Perilaku apapun ditentukan dalam sebuah penghias ditangani segera.

\n

Untuk mengimbangi ini (dan penggunaan kasus sejalan lainnya), TemplateResponse mengizinkan anda mendaftarkan callback yang akan dipanggil ketika pembangunan lengkap. Menggunakan callback ini, anda dapat menunda pengolahan kritis sampai titik dimana anda dapat menjamin bahwa isi dibangun akan tersedia.

\n

To define a post-render callback, define a function that takes\na single argument -- response -- and register that function with\nthe template response:

\n
Code
from django.template.response import TemplateResponse\n\n\ndef my_render_callback(response):\n    # Do content-sensitive processing\n    do_post_processing()\n\n\ndef my_view(request):\n    # Create a response\n    response = TemplateResponse(request, "mytemplate.html", {})\n    # Register the callback\n    response.add_post_render_callback(my_render_callback)\n    # Return the response\n    return response\n
\n

my_render_callback() akan diminta setelah mytemplate.html telah dibangun, dan akan disediakan sepenuhnya contoh TemplateResponse dibangun sebagai sebuah argumen.

\n

Jika cetakan sudah dibangun, callback akan diminta segera.

\n
\n
\n
\n

Menggunakan TemplateResponse dan SimpleTemplateResponseLink to this heading#

\n

A TemplateResponse object can be used anywhere that a normal\ndjango.http.HttpResponse can be used. It can also be used as an\nalternative to calling render().

\n

For example, the following view returns a TemplateResponse with a\ntemplate and a context containing a queryset:

\n
Code
from django.template.response import TemplateResponse\n\n\ndef blog_index(request):\n    return TemplateResponse(\n        request, "entry_list.html", {"entries": Entry.objects.all()}\n    )\n
