Disallowed Host at Django
Question:
I’m just starting out with Django for the first time. So I create a django project and run the command
python3 manage.py runserver 0.0.0.0:8000
Instead of getting the expected django homepage, I get the following error message,
DisallowedHost at /
Invalid HTTP_HOST header: '0.0.0.0:8000'. You may need to add '0.0.0.0' to ALLOWED_HOSTS.
Request Method: GET
Request URL: http://0.0.0.0:8000/
Django Version: 1.10.5
Exception Type: DisallowedHost
Exception Value:
Invalid HTTP_HOST header: '0.0.0.0:8000'. You may need to add '0.0.0.0' to ALLOWED_HOSTS.
Exception Location: /usr/local/lib/python3.5/site-packages/django/http/request.py in get_host, line 113
Python Executable: /usr/local/opt/python3/bin/python3.5
Python Version: 3.5.2
I haven’t yet scratched the surface of django, so would appreciate some help as to how to fix this?
Answers:
literally as the error suggested! go ahead and add the line
0.0.0.0 to the ALLOWED_HOSTS in your settings.py
The error info is quite explicit. It should solve the problem right away.
I too had problems with this and it is not easy for a beginner to fix. Here below is the sequence required:
First find your settings.py file, which is located:
projectName/projectName/settings.py
You can also find it using:
find -name “settings.py”
– likely you will have only one!
Once you have found this, you need to open it in a text editor and change the line
ALLOWED_HOSTS =[ ] to ALLOWED_HOSTS =[‘your.host.ip.address’] – include the ‘ ‘ and the [ ] then save.
You will have to re-start the server to get this to work eg:
python manage.py runserver your.host.ip.address:8000
If you get a syntax error, make sure you have something that looks like:
ALLOWED_HOSTS =['192.168.1.200'] or whatever your ip address is.
1- run
ifconfig
check you ip address, and you should add the ip to this lone:
ALLOWED_HOSTS =[‘you IP address goes here’]
2- run:
python manage.py your-ip:8000
3- go to your browser and check you ip:8000
1.You can also find it using: find -name “SETTINGS.py” – likely you will have only one!
2.Once you have found this, you need to open it in a text editor and change the line in the insetting File
ALLOWED_HOSTS =['Your_compte_pythonanywher.pythonanywhere.com']
Just close the postman and try request in new tab. This worked for me.
Additionally, you can have a file local_settings.py and settings.py.
If you are running in a local or a VPS server considered as local server:
python manage.py runserver 0.0.0.0:8001
You need to add in local_settings.py
Also you can search how many ALLOWED_HOSTS has your code with:
grep -rin ALLOWED_HOSTS your_source_path
