tkaemming / django-subdomains Goto Github PK

Hello! First of all, thank you very much for this project, which is being quite useful here at work :)

I have just a little suggestion for making the docs easier to understand. When you provide the example configuration with:

SUBDOMAIN_URLCONFS = {
    None: 'myproject.urls.frontend',  # no subdomain, e.g. ``example.com``
    'www': 'myproject.urls.frontend',
    'api': 'myproject.urls.api',
}

it took me a while to understand that I needed to replace the urls.py with a folder named urls containing frontend.py and api.py

I know I'm a noob and probably someone with more expertise on Django could get there faster but a little phrase referring this would be greatly appreciated :D

Sorry for my bad English and thanks in advance for your attention on this subject…
Keep up the good work!

Hello,
I've spent whole day at searching for solution for problem: subdomains worked only on first request after server (re)start.
The answer is in function get_domain_for_request() - it returns 'domain.tld' on first request, but on every next request it gives 'http://domain.tld'.

Not elegant, but working quick workaround I used is to add a few lines to get_domain_for_request():

    def get_domain_for_request(self, request):
        """
        Returns the domain that will be used to identify the subdomain part
        for this request.
        """
        domain = get_domain()

        if 'https://' in domain:
            domain = domain.replace('https://', '')
        elif 'http://' in domain:
            domain = domain.replace('http://', '')

        return domain

Because of the exception raised you can't change the domain in the admin. It would be nice if the exception would not be raised if request.path starts with /admin/

I am able to configure the subdomain fine, however if I try to load the templates with RequestContext I get error -
NoReverseMatch at /home/
u'social' is not a registered namespace

e.g.
urls.py
urlpatterns = patterns(
'',
url(r'^home/$', 'sampleapp.views.subdomain_home', name='subdomain_home'),
)

view
def subdomain_home(request):
return render_to_response(
'subdomain_home.html',
RequestContext(request)
)

If I remove the RequestContext it works fine (though I run into issue with loading my static files). I believe I am not doing something right configuration wise.

Can someone help? happy to provide more details.

This project is popular/ was popular with the django community, please can it be migrated to the jazzband project so it may continue to be supported in the future. I have recently helped migrate the dj-database-url project to jazzband so i can lend a hand if needed.

The dict.iterkeys(), dict.iteritems() and dict.itervalues() methods are no longer supported in Python 3.0.
Instead use dict.keys(), dict.items() and dict.values().

Hi,

I just updated to django 2.0 and the import of reverse is broken

File "lib/python3.6/site-packages/subdomains/utils.py", line 8, in
from django.core.urlresolvers import reverse as simple_reverse
ModuleNotFoundError: No module named 'django.core.urlresolvers'

Now, reverse is in django.urls

The subdomainurls url tag doesn't accept the scheme argument, utils.reverse accepts a scheme argument but I can't see how to pass it from the tag.
I was hoping to be able to have something like {% url 'the-url' scheme='https' %}

SUBDOMAIN_URLCONFS = {
None: servers.urls',
'ololo': servers.urls.other',

}
open in browser ololo.domain.com
#~ ololo.domain.com in hosts
#~ domain.com is nginx hostname
then see error page with string:
Using the URLconf defined in servers.urls, Django tried these URL patterns, in this order:

how to fix it?

answer
check defined SIDE_ID from app Sites x_x

django supports this syntax for url tag:

{% url 'path.to.view' arg arg2 as the_url %}
<a href="{{ the_url }}">I'm linking to {{ the_url }}</a>

https://docs.djangoproject.com/en/dev/ref/templates/builtins/#url

But if i try to use your template tag i get django.template.base.TemplateSyntaxError:

TemplateSyntaxError: 'url' received some positional argument(s) after some keyword argument(s)

This syntax is really helpful if i have to include another template snippet that's usefull on multiple pages and just pass it some predetermined values for current template context, and it's really clean way to do it.

Example:

{% url 'make_donation' fundraiser_id=fundraiser.id as donation_url %}
{% include 'fundraisers/snippets/donate_box.html' with active=fundraiser.active closed_msg=closed_msg donation_url=donation_url %}

parse_bits locals:

{'takes_context': True, 'parser': <django.template.debug.DebugParser object at 0x7f1d87cba050>, 'name': 'url', 'bits': [u"'make_donation'", u'fundraiser_id=fundraiser.id', u'as', u'donation_url'], 'args': [<django.template.base.FilterExpression object at 0x7f1d87cd0610>], 'param': u'fundraiser_id', 'varargs': 'args', 'kwarg': {}, 'params': ['view', 'subdomain'], 'value': <django.template.base.FilterExpression object at 0x7f1d87cd04d0>, 'unhandled_params': ['subdomain'], 'kwargs': {'fundraiser_id': <django.template.base.FilterExpression object at 0x7f1d87cd04d0>}, 'bit': u'as', 'varkw': 'kwargs', 'defaults': (<object object at 0x7f1d8c075290>)  }

When I run my unit test I always get this warning. That's very annoying, because I can't just disable it, but need to provide special fixture or manually add Site to the database that's very confusing and violates DRY principle.

I think that the right solution is to add additional variable or use USE_SUBDOMAIN_EXCEPTION with 3 states: 'exception', 'warning', 'disabled'.

How can I test my subdomains locally? For example:

I want to enter test-subdomain.develop:8000 into my browser, and see my site at that subdomain. If I have 'test-subdomain' in my SUBDOMAIN_URLCONF, what else do I have to do to make this work? I tried adding a site to my django_site table, but it didn't work. I tried to add the following to the django_site table:

test-subdomain.develop
test-subdomain.develop:8000
test-subdomain.realdomain.com

Thanks for your time; it seems like I should be seeing a solution, but I'm not sure where to go for next troubleshooting steps.

www.foo.com:8000 isn't recognised as being a subdomain of foo.com:9000.

I ran into this problem when using port-forwarding on a Vagrant machine in which I was running a project with subdomains. The problematic code is in this method and is easily resolved by disregarding the port number.

I'd be more than happy to submit a PR for this if you think this issue is valid.

Hello!

I have the question about reverse function.

reverse have following check:

    domain = get_domain()
    if subdomain is not None:
        domain = '%s.%s' % (subdomain, domain)

But if subdomain is empty string (''), then we get domain equals to .examle.org, what completely doesn't have sense.

So maybe changing check to

    domain = get_domain()
    if subdomain:
        domain = '%s.%s' % (subdomain, domain)

will be better? If subdomain is empty string, then we use main domain. Everyone is happy!

In my code I add subdomains dynamically and sometimes I need to reverse them. Empty subdomain is my main page and I want to resolve it to main domain.

Thanks!

If USE_SUBDOMAIN_EXCEPTION is set to True and the domain requested was Upfront.com and the site object says upfront.com you will get an exception.

Hey. Just started using the package. Great work so far. But! We're making heavy use of namespaced URLs which seem to be incompatible.

The offending part seems to be at subdomains/compat/template.py line 123:

I'm not sure it makes sense to compile filters on the URL name - but then again I haven't dug into the rest of the code.

I'm trying to use one Django instance for main domain and for one subdomain on it.
I've placed everything related to the subdomain in a single app.
And I've run into a critical issue: cache can't differentiate between domains. So now it's showing the same page on domain and subdomain, whichever root was visited first after caches were expired/cleared.

So far I've found several workarounds for this:

• Adding yet another middleware and wrapping every view in vary_on_headers: http://stackoverflow.com/a/9701153
• Using KEY_FUNCTION, what function can you suggest? http://stackoverflow.com/a/21751108

What is the best solution in your opinion? Apart from considering it being a bug, I need a workaround yesterday.

@tkaemming Can you please tell me how I can route to dynamic subdomains. By dynamic I meant like slack use to do they give every team/organization unique subdomain. Right now I have to hard code the subdomains.??

I have installed django-subdomains using pip, and it's available in site-packages.

I set up django-subdomains following this [guide][1].

I set my subdomain urlconfs as follows:

    SUBDOMAIN_URLCONFS = {
         None: 'mysite.urls',
        'www': 'mysite.urls',
        'shop': 'mysite.urls.shop',
        'blog': 'mysite.urls.blog'
    }

Everything works nicely, but I can't really test it cause when I run my app on my local host using python manage.py runserver, I can't really add the subdomains. If go to http://blog.127.0.0.1:8000, then the browser says a server cannot be found. Is there any way to set my server in such a way that allows for testing?

I also have this following line in my console:
No handlers could be found for logger "subdomains.middleware"

How can I get this working? If anyone wants, my settings.py file can be found here:

Thank you.

Hi, i have a problem in the templates for creating the urls. for example:

Hi,

Thanks for the awesome work on django-subdomains. I'm trying to incorporate it in my project, but there's an issue I'm not quite sure how to handle:
Let's say I have a abc subdomain and a www subdomain, and I want my view in the abc domain to use Django's reverse() function to another view in the www subdomain. However, because the 2 URLconfs are seperated, reverse() will throw an error instead of correctly finding the view in the www urlconf.
Is there an easy way around this?

I am using django-subdomains to enable subdomains for two different apps in my django project, and it seems work well. The one thing I'm having trouble with is reverse-lookup urls in the template tags.

(I'm on Python 2.7, Django 1.6.5)

If I am using the basic {% url 'foo_view' %}, these URLs resolve fine. However, after I add the call {% load subdomainurls %} to the top of my template:

• {% url 'foo_view' subdomain='www'%} works
• {% url 'foo_view' %} does not, and raises a NoReverseMatch exception

Nothing else in the template or project has changed. This happens even though the django-subdomains docs state that:

If request is in the template context when rendering and no subdomain is provided, the URL will be attempt to be resolved by relative to the current subdomain. If no request is available, the URL will be resolved using the same rules as a call to subdomains.utils.reverse() without a subdomain argument value.

So, it seems like my app is demanding that I add a subdomain='foo' to the url call (it works when I add that!), even though the docs say it should handle it fine without the subdomain. Is there a reverse-lookup "helper" that I need to add somewhere? ...or is this possibly broken?

related to #9

Right now, django-subdomains only support reverse(). I would like the ability to lazily reverse subdomain urls.

Hi, I am using Django 1.9 with Python 3.4 and when I try to run this library I get the following error:

File "/Users/xxx/Developer/rodolfomartinez/yyyy/py-zzzzz/env/lib/python3.4/site-packages/subdomains/utils.py", line 2, in <module>
    from urlparse import urlunparse
ImportError: No module named 'urlparse'

The solution to having this library support the missing library is to have this project import urllib and have utils.py have the following code:

try:
    from urllib.parse import urlparse
except ImportError:
    from urlparse import urlparse

I keep getting this error

RuntimeError: Model class django.contrib.sites.models.Site doesn't declare an explicit app_label and either isn't in an application in INSTALLED_APPS or else was imported before its application was loaded.

Using sitemaps together with the reverse function on get_absolute_url in a model results in sitemaps with duplicate protocol/domain pairs.

This might be Django's problem (not checking for an absolute url before pre-pending the site domain) but a workaround would be useful.

I have this entry in one of my subdomains urls.py:

url(r'^register/$', SendUserProfileCreationLinkView.as_view(), name='send_userprofile_creation_link'),

When i put in my browser:

subdomain.domain/register/

i get the correct view displayed, but when i try to surf the same url without the trailing slash, like this

subdomain.domain/register

i get a Page Not Found error.

But i don't get this kind of errors in my domain urls (i get redirected to the correct url with a trailing slash). Is there any reason of why this is working like this or is it a bug?

Hey,

I've been using django-subdomains for a while now.
Since I'm working with different domains for my site I set the ROOT_URLCONF to a specific app knowing that all other domains that are not set in the django_sites table will go to that app.

Every time a user gets to my server from a different domain (one not in the django_site table) I get a log record like so:
WARNING:subdomains.middleware:The host does not belong to the domain <site_id Domain>, unable to identify the subdomain for this request

Is there a way to cancel this log records? I'm afraid that in scale i'll get slower results..

Best,
Guy
