# django-host-user-override
2+
3+
Overrides current user based on host prefix. For example any request to
4+
```5.user.example.com``` becomes request as if you were logged in as
5+
user with ID 5. Works only if you're actually logged in as superuser.
6+
7+
Also gives you big red banner on top of every page if your user is
8+
overridden.
9+
10+
### Installing django-host-user-override
11+
12+
1. Install the package from PyPI: ```pip install django-host-user-override```
13+
14+
2. Add ```host_user_override``` to ```INSTALLED_APPS```:
15+
```python
16+
INSTALLED_APPS = [
17+
...,
18+
'host_user_override',
19+
...,
20+
]
21+
```
22+
23+
3. Add ```HostUserOverrideMiddleware``` right after ```AuthenticationMiddleware```:
24+
```python
25+
MIDDLEWARE = [
26+
...,
27+
'django.contrib.auth.middleware.AuthenticationMiddleware',
28+
'host_user_override.middleware.HostUserOverrideMiddleware',
29+
...,
30+
]
31+
```
32+
33+
4. Update your ```settings.py``` file to support subdomains (don't forget about DNS as well):
34+
```python
35+
ALLOWED_HOSTS = ['.example.com']
36+
37+
SESSION_COOKIE_DOMAIN = '.example.com'
38+
```
39+
40+
5. Set new ```change_form.html``` template in ```UserAdmin```:
41+
```python
42+
admin.site.unregister(User)
43+
44+
@admin.register(User)
45+
class CustomUserAdmin(UserAdmin):
46+
change_form_template = 'host_user_override/change_form.html'
47+
```
48+
49+
## Usage
50+
51+
Open any non-superuser in Django Admin and press 'Login as multiuser' button.
