Django Handling 500 Error
Contents |
A view function, or view for short, is simply a Python function that takes a Web request and returns a Web response. This response django 500 error log can be the HTML contents of a Web page, or a

redirect, or a 404 error, or an XML document, or an image . . . or anything, really.
Django 500 Error Template
The view itself contains whatever arbitrary logic is necessary to return that response. This code can live anywhere you want, as long as it's on your Python path. There's

no other requirement-no "magic," so to speak. For the sake of putting the code somewhere, the convention is to put views in a file called views.py, placed in your project or application directory. A simple view¶ Here's a view that returns the current date and time, as an HTML document: from django.http import HttpResponse import datetime def django raise 500 error current_datetime(request): now = datetime.datetime.now() html = "
It is now %s." % now return HttpResponse(html) Let's step through this code one line at a time: First, we import the class HttpResponse from the django.http module, along with Python's datetime library. Next, we define a function called current_datetime. This is the view function. Each view function takes an HttpRequest object as its first parameter, which is typically named request. Note that the name of the view function doesn't matter; it doesn't have to be named in a certain way in order for Django to recognize it. We're calling it current_datetime here, because that name clearly indicates what it does. The view returns an HttpResponse object that contains the generated response. Each view function is responsible for returning an HttpResponse object. (There are exceptions, but we'll get to those later.)

I find this behaviour strange... python django http templates share|improve this question asked Feb 6 '13 at 14:55 heri0n 51521129 add a comment| 3 Answers 3 active oldest votes up vote 7 down vote accepted The HttpResponseServerError inherits from HttpResponse and is actually quite simple: class HttpResponseServerError(HttpResponse): status_code = 500 So let's look at the HttpResponse constructor: def __init__(self, content='', *args, **kwargs): super(HttpResponse, self).__init__(*args, **kwargs) # Content is a bytestring. See the `content` property methods. self.content = content As you can see by default content is empty. Now, let's take a look at how it is called by Django itself (an excerpt from django.views.defaults): def server_error(request, template_name='500.html'): """ 500 error handler. Templates: :template:`500.html` Context: None """ try: template = loader.get_template(template_name) except TemplateDoesNotExist: return http.HttpResponseServerError('

But is it better to just put that config in nginx ? This ST thread has the solution for putting it. - http://stackoverflow.com/questions/1024199/nginx-customizing-404-page Is that how everyone handles it when using nginx ?

If a 404 occurs, the webserver should detect it and display my static page. Same for 500. –PlanetUnknown Sep 25 '10 at 12:18 add a comment| 3 Answers 3 active oldest votes up vote 2 down vote accepted You haven't mentioned any reasons why you would want to put these pages in the Nginx server. I would recommend keeping it with the rest of your site, that is, on the Django server. Moving part of your site to the Nginx server is a good idea to solve scalability problem, but complicates your deploy. I certainly hope you aren't seeing a significant fra
About Contact « Back to Home Page or Back to Books and Articles by the Author Django recipes Go to Table of Contents Set up HTTP handling in Django view methods: HTTP errors, redirects, content types and status codes Problem You want to use HTTP handling directly in Django views to output HTTP error pages, HTTP redirects, HTTP content types (e.g. text/plain, text/xml) and HTTP status codes ('HTTP 200 for "OK"','HTTP 404 for "NOT FOUND"'). Solution Use the status and content_type arguments with the django.shortcuts.render method to specify an HTTP status code and HTTP content type, respectively. To trigger an HTTP 500 (INTERAL SERVER ERROR) response do raise Exception in a view. To trigger an HTTP 404 (NOT FOUND) response do raise django.http.Http404. To trigger an HTTP 400 (BAD REQUEST) response do raise django.core.exceptions.SuspiciousOperation. To trigger an HTTP 403 (FORBIDDEN) response do raise django.core.exceptions.PermissionDenied. You can customize the pages for HTTP 404, HTTP 500, HTTP 400 and HTTP 403 responses creating templates called 404.html, 500.html, 400.html and 403.html, respectively. Custom templates must be placed in a folder defined in the DIRS list of the TEMPLATES variable. You can also override the built-in view methods for HTTP 404, HTTP 500, HTTP 400 and HTTP 403 responses defining custom view methods in the variables handler404, handler500, handler400 and handler403. The variables for custom view methods must be defined in urls.py. To do an HTTP redirect you can use django.http.HttpResponsePermanentRedirect() or django.http.HttpResponseRedirect(). To trigger an HTTP 304 (NOT MODIFIED) response use django.http.HttpResponseNotModified(). To trigger an HTTP 400 (BAD REQUEST) response with in-line content use django.http.HttpResponseBadRequest(). To trigger an HTTP 404 (NOT FOUND) response with in-line content use django.http.HttpResponseNotFound(). To trigger an HTTP 403 (FORBIDDEN) response with in-line content use django.http.HttpResponseForbidden(). To trigger an HTTP 405 (METHOD NOT ALLOWED) response with in-line content use django.http.HttpResponseNotAllowed(). To trigger an HTTP 410 (GONE) response with in-line content use django.http.HttpResponseGone().
