I have a simple chat application in Tornado powered with RethinkDB.
Am trying to integrate this tornado chat application to run with django site.
For that reason, I have adopted below in rechat.py in order for it to work with django.
Namespaces tornado.wsgi and django.core.wsgi (get_wsgi_application)
Set environment variable for Django settings.py
os.environ['DJANGO_SETTINGS_MODULE'] = 'djangoapp.settings'
When I try to run it after the above changes, it connects the db server, but doesn't do anything. What am I missing?
How can I make this tornado app to work with django 1.8 site?
Below is my code of rechat.py (https://github.com/v3ss0n/rechat) -

I have a CrawlSpider, the code is below. I use Tor through tsocks.
When I start my spider, everything works fine. Using init_request I can login on site and crawl with sticky cookies.
But problem occurred when I stopped and resumed spider. Cookies became not sticky.
I give you the response from Scrapy.
=======================INIT_REQUEST================
2013-01-30 03:03:58+0300 [my] INFO: Spider opened
2013-01-30 03:03:58+0300 [my] INFO: Resuming crawl (675 requests scheduled)
............ And here crawling began
So... callback=self.login_url in def init_request is not fired!!!
I thought that scrapy engine didn't want to send again request on login page. Before resuming scrapy I changed login_page (I can login from every page on site) to different that not included in restrict_xpaths.
Result is - After resuming I cannot login and previous cookies are lost.
Does anyone have some assumptions?

The init_request(self): is available only when you subclass from InitSpider not CrawlSpider
You need to subclass your spider from InitSpider like this
class WorkingSpider(InitSpider):
login_page = 'http://www.example.org/login.php'
def init_request(self):
#"""This function is called before crawling starts."""
return Request(url=self.login_page, callback=self.login)
But then remember that you can't define Rules in initSpider as its only avaiable in CrawlSpider you need to manually extract the links
I was just wondering if there's any reasonable way to pass authentication cookies from webdriver.Firefox() instance to the spider itself? It would be helpful to perform some webdriver stuff and then go about scraping "business as usual". Something to the effect of:
def __init__(self):
BaseSpider.__init__(self)
self.selenium = webdriver.Firefox()
def __del__(self):
self.selenium.quit()
print self.verificationErrors
def parse(self, response):
# Initialize the webdriver, get login page
sel = self.selenium
sel.get(response.url)
sleep(3)
##### Transfer (sel) cookies to (self) and crawl normally??? #####
...
...
Transfer Cookies from Selenium to Scrapy Spider
Scrapying File
from selenium import webdriver
driver=webdriver.Firefox()
data=driver.get_cookies()
# write to temp file
with open('cookie.json', 'w') as outputfile:
json.dump(data, outputfile)
driver.close()
outputfile.close()
....
Spider
import os
if os.stat("cookie.json").st_size > 2:
with open('./cookie.json', 'r') as inputfile:
self.cookie = json.load(inputfile)
inputfile.close()
You can try to override BaseSpider.start_requests method to attach to starting requests needed cookies using scrapy.http.cookies.CookieJar.

This works with chrome driver but not Firefox (Tested OK)
refer https://christopher.su/2015/selenium-chromedriver-ubuntu/ for installation.
import scrapy
from scrapy.spiders.init import InitSpider
from scrapy.http import Request
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
import pickle
class HybridSpider(InitSpider):
name = 'hybrid'
def init_request(self):
driver = webdriver.Chrome()`
driver.get('https://example.com')
driver.find_element_by_id('js-login').click()
driver.find_element_by_id('email').send_keys('mymail#example.net')
driver.find_element_by_id('password').send_keys('mypasssword',Keys.ENTER)
pickle.dump( driver.get_cookies() , open(os.getenv("HOME")+"/my_cookies","wb"))
cookies = pickle.load(open(os.getenv("HOME")+"/my_cookies", "rb"))
FH = open(os.getenv("HOME")+"/my_urls", 'r')
for url in FH.readlines():
pass
yield Request(url,cookies=cookies,callback=self.parse)
def parse(self, response):
pass
Haven't tried directly passing the cookies like
yield Request(url,cookies=driver.get_cookies(),callback=self.parse)
Might work too..
driver = webdriver.Chrome()
Then perform the login or interact with the page through the browser. Now when using the crawler in scrapy, set the cookies parameter:
request = Request(URL, cookies=driver.get_cookies(), callback=self.mycallback)
I am using Django for a project and is already in production.
In the production environment 500.html is rendered whenever a server error occurs.
How do I test the rendering of 500.html in dev environment? Or how do I render 500.html in dev, if I turn-off debug I still get the errors and not 500.html
background: I include some page elements based on a page and some are missing when 500.html is called and want to debug it in dev environment.
I prefer not to turn DEBUG off. Instead I put the following snippet in the urls.py:
if settings.DEBUG:
urlpatterns += patterns('',
(r'^500/$', 'your_custom_view_if_you_wrote_one'),
(r'^404/$', 'django.views.generic.simple.direct_to_template', {'template': '404.html'}),
)
In the snippet above, the error page uses a custom view, you can easily replace it with Django's direct_to_template view though.
Now you can test 500 and 404 pages by calling their urls: http://example.com/500 and http://example.com/404
In Django 1.6 django.views.generic.simple.direct_to_template does not exists anymore, these are my settings for special views:
# urls.py
from django.views.generic import TemplateView
from django.views.defaults import page_not_found, server_error
urlpatterns += [
url(r'^400/$', TemplateView.as_view(template_name='400.html')),
url(r'^403/$', TemplateView.as_view(template_name='403.html')),
url(r'^404/$', page_not_found),
url(r'^500/$', server_error),
]
And if you want to use the default Django 500 view instead of your custom view:
if settings.DEBUG:
urlpatterns += patterns('',
(r'^500/$', 'django.views.defaults.server_error'),
(r'^404/$', 'django.views.generic.simple.direct_to_template', {'template': '404.html'}),
)
Continuing shanyu's answer, in Django 1.3+ use:
if settings.DEBUG:
urlpatterns += patterns('',
(r'^500/$', 'django.views.defaults.server_error'),
(r'^404/$', 'django.views.defaults.page_not_found'),
)
For Django > 3.0, just set the raise_request_exception value to False.
from django.test import TestCase
class ViewTestClass(TestCase):
def test_error_page(self):
self.client.raise_request_exception = False
response = self.client.get(reverse('error-page'))
self.assertEqual(response.status_code, 500)
self.assertTrue(
'some text from the custom 500 page'
in response.content.decode('utf8'))
Documentation: https://docs.djangoproject.com/en/3.2/topics/testing/tools/
NOTE: if the error page raises an exception, that will show up as an ERROR in the test log. You can turn the test logging up to CRITICAL by default to suppress that error.
Are both debug settings false?
settings.DEBUG = False
settings.TEMPLATE_DEBUG = False
How i do and test custom error handlers

Update for Django > 1.6 and without getting
page_not_found() missing 1 required positional argument: 'exception'
Inspired by this answer:
# urls.py
from django.views.defaults import page_not_found, server_error, permission_denied, bad_request
[...]
if settings.DEBUG:
# This allows the error pages to be debugged during development, just visit
# these url in browser to see how these error pages look like.
urlpatterns += [
path('400/', bad_request, kwargs={'exception': Exception('Bad Request!')}),
path('403/', permission_denied, kwargs={'exception': Exception('Permission Denied')}),
path('404/', page_not_found, kwargs={'exception': Exception('Page not Found')}),
path('500/', server_error),
You can simply define the handler404 and handler500 for errors in your main views.py file as detailed in this answer:
https://stackoverflow.com/a/18009660/1913888
This will return the error that you desire when Django routes to that handler. No custom URL configuration is needed to route to a different URL name.
In Django versions < 3.0, you should do as follows:

Is there a way I can apply the login_required decorator to an entire app? When I say "app" I mean it in the django sense, which is to say a set of urls and views, not an entire project.
Yes, you should use middleware.
Try to look through solutions which have some differences:
http://www.djangosnippets.org/snippets/1179/ - with list of exceptions.
http://www.djangosnippets.org/snippets/1158/ - with list of exceptions.
http://www.djangosnippets.org/snippets/966/ - conversely with list of login required urls.
http://www.djangosnippets.org/snippets/136/ - simplest.
As of Django 3+, you can set login_require() to an entire app by applying a middleware. Do like followings:
Step 1: Create a new file anything.py in your yourapp directory and write the following:
import re
from django.conf import settings
from django.contrib.auth.decorators import login_required
//for registering a class as middleware you at least __init__() and __call__()
//for this case we additionally need process_view() which will be automatically called by Django before rendering a view/template
class ClassName(object):
//need for one time initialization, here response is a function which will be called to get response from view/template
def __init__(self, response):
self.get_response = response
self.required = tuple(re.compile(url) for url in settings.AUTH_URLS)
self.exceptions = tuple(re.compile(url)for url in settings.NO_AUTH_URLS)
def __call__(self, request):
//any code written here will be called before requesting response
response = self.get_response(request)
//any code written here will be called after response
return response
//this is called before requesting response
def process_view(self, request, view_func, view_args, view_kwargs):
//if authenticated return no exception
if request.user.is_authenticated:
return None
//return login_required()
for url in self.required:
if url.match(request.path):
return login_required(view_func)(request, *view_args, **view_kwargs)
//default case, no exception
return None
Step 2: Add this anything.py to Middleware[] in project/settings.py like followings
MIDDLEWARE = [
// your previous middleware
'yourapp.anything.ClassName',
]
Step 3: Also add the following snippet into project/settings.py
AUTH_URLS = (
//disallowing app url, use the url/path that you added on mysite/urls.py (not myapp/urls.py) to include as your app urls
r'/your_app_url(.*)$',
)
I think you are looking for this snippet, containing login-required middleware.
This is an old question. But here goes:
Django Decorator Include
This is a substitute of include in URLConf. Pefect for applying login_required to an entire app.
I clicked all the links in the anwsers, but they were all based on some kind of regular expressions. On Django 3+ you can do the following to restrict for a specific app:
Declare app_name="myapp" in your app's urls.py (https://docs.djangoproject.com/en/3.2/intro/tutorial03/#namespacing-url-names)
(now all these urls should be called with there namespace "myapp:urlname")
Create a middleware.py file in your app with this:
from django.contrib.auth.views import redirect_to_login
from django.core.exceptions import ImproperlyConfigured
from django.urls import resolve
class LoginRequiredAccess:
"""All urls starting with the given prefix require the user to be logged in"""
APP_NAME = 'myapp'
def __init__(self, get_response):
self.get_response = get_response
def __call__(self, request):
if not hasattr(request, 'user'):
raise ImproperlyConfigured(
"Requires the django's authentication middleware"
" to be installed.")
user = request.user
if resolve(request.path).app_name == self.APP_NAME: # match app_name defined in myapp.urls.py
if not user.is_authenticated:
path = request.get_full_path()
return redirect_to_login(path)
return self.get_response(request)
Put "myapp.middleware.LoginRequiredAccess" in your MIDDLEWARE constant from settings.py
Then in your main project urls.py
urlpatterns = [
path('foobar', include('otherapp.urls')), # this will not be redirected
path('whatever', include('myapp.urls')), # all these urls will be redirected to login
]
On of the avantage of this method is it can still works with a root url path, e.g path('', include('myapp.urls')), while the others will do an infinite redirect loop.
I'm wondering if there is any solution to make it works like this:
/app/app.py
class AppConfig(AppConfig):
login_required = True
/project/urls.py
urlpatterns = [
url(r'app/', include('app.urls', namespace='app'))
]
/common/middleare.py
def LogMiddleware(get_response):
def middleware(request):
# solution 1
app = get_app(request)
if app.login_required is True and request.is_authenticated is Fasle:
return HttpResponseRedirect(redirect_url)
# solution 2
url_space = get_url_space(request.get_raw_uri())
if url_space.namespace in ['app', 'admin', 'staff', 'manage'] and \
request.is_authenticated is False:
return HttpResponseRedirect(redirect_url)
I will check if there is any methoded to get the app or url name of a request. I think it looks prettier.
