Django - what is the difference between render(), render_to_response() and direct_to_template()?
render(request, template[, dictionary][, context_instance][, content_type][, status][, current_app])
render() is a brand spanking new shortcut for
render_to_response in 1.3 that will automatically use
RequestContext that I will most definitely be using from now on.
2020 EDIT: It should be noted that
render_to_response() was removed in Django 3.0
render_to_response(template[, dictionary][, context_instance][, mimetype])¶
render_to_response is your standard render function used in the tutorials and such. To use
RequestContext you'd have to specify
direct_to_template is a generic view that I use in my views (as opposed to in my urls) because like the new
render() function, it automatically uses
RequestContext and all its
direct_to_template should be avoided as function based generic views are deprecated. Either use
render or an actual class, see https://docs.djangoproject.com/en/1.3/topics/generic-views-migration/
I'm happy I haven't typed
RequestContext in a long, long time.
Rephrasing Yuri, Fábio, and Frosts answers for the Django noob (i.e. me) - almost certainly a simplification, but a good starting point?
render_to_response()is the "original", but requires you putting
context_instance=RequestContext(request)in nearly all the time, a PITA.
direct_to_template()is designed to be used just in urls.py without a view defined in views.py but it can be used in views.py to avoid having to type RequestContext
render()is a shortcut for
render_to_response()that automatically supplies
context_instance=Request....Its available in the django development version (1.2.1) but many have created their own shortcuts such as this one, this one or the one that threw me initially, Nathans basic.tools.shortcuts.py
def render(request, *args, **kwargs): """ Simple wrapper for render_to_response. """ kwargs['context_instance'] = RequestContext(request) return render_to_response(*args, **kwargs)
So there is really no difference between
render_to_response except it wraps your context making the template pre-processors work.
Direct to template is a generic view.
There is really no sense in using it here because there is overhead over
render_to_response in the form of view function.
