Django Error Page 500
Contents |
When you're running a public site you should always turn off the DEBUG setting. django custom 500 error page That will make your server run much faster, and will django 500 error log also prevent malicious users from seeing details of your application that can be revealed django 500 error template by the error pages. However, running with DEBUG set to False means you'll never see errors generated by your site - everyone will django server error 500 just see your public error pages. You need to keep track of errors that occur in deployed sites, so Django can be configured to create reports with details about those errors. Email reports¶ Server errors¶ When DEBUG is False, Django will email the users listed in the

ADMINS setting whenever your code raises an unhandled exception and results in an internal server error (HTTP status code 500). This gives the administrators immediate notification of any errors. The ADMINS will get a description of the error, a complete Python traceback, and details about the HTTP request that caused the error. Note In order to send email, Django requires a few settings telling it how to connect to your mail server. At the very least, you'll need to specify EMAIL_HOST and possibly EMAIL_HOST_USER and EMAIL_HOST_PASSWORD, though other settings may be also required depending on your mail server's configuration. Consult the Django settings documentation for a full list of email-related settings. By default, Django will send email from root@localhost. However, some mail providers reject all email from this address. To use a different sender address, modify the SERVER_EMAIL sett
A view function, or view for short, is simply a Python function that takes a Web request and returns a Web response. This response can be the HTML contents

of a Web page, or a redirect, or a 404 error, or an joomla 500 error XML document, or an image . . . or anything, really. The view itself contains whatever arbitrary logic is django debug false 500 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 https://docs.djangoproject.com/en/1.10/howto/error-reporting/ 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 current_datetime(request): now = datetime.datetime.now() html = "
It is now %s." % now return HttpResponse(html) Let's step https://docs.djangoproject.com/en/1.10/topics/http/views/ 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.) Django's Time Zone Django includes a TIME_ZONE setting that defaults to America/Chicago. This probably isn't where you live, so you might want to change it in your settings file. Mapping URLs to views¶ So, to recap, this view function returns an HTML page that includes the current date and time. To display this view at a particula27 Potential fix: There are two potential reasons for this error. Ensure that ALLOWED_HOSTS is http://uxscrutiny.com/2014/03/404-and-500-errors-in-django/ configured properly in the settings file. In the default settings file, https://gist.github.com/revolunet/809780 there's a line for ALLOWED_HOSTS=[]. In my case, I was deploying things locally, so I edited this line to be ALLOWED_HOSTS=['127.0.01','localhost']. If you're deploying things on a specific domain, list that here. Others have suggested using ALLOWED_HOSTS=['*'], but this setting should really only be used for testing deployments, 500 error as it's not a secure setting for production deployment scenarios. Create a template for 500 errors. Note that the docs recommend you create a template that is very simple because you can never know for sure why the error was generated. In other words, you can't rely on something that might potentially be broken; that's why the sample one mentioned django 500 error in the docs doesn't do anything fancy and doesn't use any template inheritance. One quick note about creating a 500-error template: in my case, I wanted my 500 page, like my 404 page, to fit in with the same look & feel as the rest of the site. This meant utilizing template inheritance (i.e., {% extends "base.html" %}). Now, even though the docs say this is no-no, it ended up working out OK. At first, I ran into this error message: OfflineGenerationError: You have offline compression enabled but key "SOMEKEYHERE" is missing from offline manifest. You may need to run "python manage.py compress" Following the suggestion made here, I got things working again by using a custom class-based view. [Side note: it looks like offline generation loads the manifest once, and then remembers the result so that it doesn't have to refetch it on every request. What this means is that once I got offline compression working (by using the custom class-based view), it's possible to remove the code for the custom v

The beauty of HttpResponseServerError that doesn't seem to be documented (that I can see) is that it will still send emails to ADMINS if you use if for handler500. bharling commented Apr 25, 2014 exactly what i was after! lquixada commented Jul 3, 2014 works great but you missed to import the loader from django.template, this way you can call loader.get_template correctly Sign up for free to join this conversation on GitHub.
