Seahub Settings¶

Tip

You can also modify most of the config items via web interface. The config items are saved in database table (seahub-db/constance_config). They have a higher priority over the items in config files. If you want to disable settings via web interface, you can add ENABLE_SETTINGS_VIA_WEB = False to seahub_settings.py.

Sending Email Notifications on Seahub¶

Refer to email sending documentation.

Cache¶

Seahub caches items(avatars, profiles, etc) on file system by default(/tmp/seahub_cache/). You can replace with Memcached or Redis.

MemcachedRedis

# on Debian/Ubuntu 18.04+
apt-get install memcached libmemcached-dev -y
pip3 install --timeout=3600 pylibmc django-pylibmc

systemctl enable --now memcached

Add the following configuration to seahub_settings.py.

CACHES = {
    'default': {
        'BACKEND': 'django_pylibmc.memcached.PyLibMCCache',
        'LOCATION': '127.0.0.1:11211',
    },
}

Redis supported is added in Seafile version 11.0

Install Redis with package installers in your OS.
Please refer to Django's documentation about using Redis cache.

Cloud Mode¶

You should enable cloud mode if you use Seafile with an unknown user base. It disables the organization tab in Seahub's website to ensure that users can't access the user list. Cloud mode provides some nice features like sharing content with unregistered users and sending invitations to them. Therefore you also want to enable user registration. Through the global address book (since version 4.2.3) you can do a search for every user account. So you probably want to disable it.

# Enable cloude mode and hide `Organization` tab.

# Disable global address book
ENABLE_GLOBAL_ADDRESSBOOK = False

Single Sign On¶

# Enable client to open an external browser for single sign on
# When it is false, the old buitin browser is opened for single sign on
# When it is true, the default browser of the operation system is opened
# The benefit of using system browser is that it can support hardware 2FA
# Since 11.0.0, and sync client 9.0.5, drive client 3.0.8
CLIENT_SSO_VIA_LOCAL_BROWSER = True   # default is False
CLIENT_SSO_UUID_EXPIRATION = 5 * 60   # in seconds

REST_FRAMEWORK_THROTTING_WHITELIST = []

Seahub Custom Functions¶

Since version 6.2, you can define a custom function to modify the result of user search function.

For example, if you want to limit user only search users in the same institution, you can define custom_search_user function in {seafile install path}/conf/seahub_custom_functions/__init__.py

Code example:

import os
import sys

current_path = os.path.dirname(os.path.abspath(__file__))
seahub_dir = os.path.join(current_path, \
        '../../seafile-server-latest/seahub/seahub')
sys.path.append(seahub_dir)

from seahub.profile.models import Profile
def custom_search_user(request, emails):

    institution_name = ''

    username = request.user.username
    profile = Profile.objects.get_profile_by_user(username)
    if profile:
        institution_name = profile.institution

    inst_users = [p.user for p in
            Profile.objects.filter(institution=institution_name)]

    filtered_emails = []
    for email in emails:
        if email in inst_users:
            filtered_emails.append(email)

    return filtered_emails

You should NOT change the name of custom_search_user and seahub_custom_functions/__init__.py

Since version 6.2.5 pro, if you enable the ENABLE_SHARE_TO_ALL_GROUPS feather on sysadmin settings page, you can also define a custom function to return the groups a user can share library to.

For example, if you want to let a user to share library to both its groups and the groups of user test@test.com, you can define a custom_get_groups function in {seafile install path}/conf/seahub_custom_functions/__init__.py

Code example:

import os
import sys

current_path = os.path.dirname(os.path.abspath(__file__))
seaserv_dir = os.path.join(current_path, \
        '../../seafile-server-latest/seafile/lib64/python2.7/site-packages')
sys.path.append(seaserv_dir)

def custom_get_groups(request):

    from seaserv import ccnet_api

    groups = []
    username = request.user.username

    # for current user
    groups += ccnet_api.get_groups(username)

    # for 'test@test.com' user
    groups += ccnet_api.get_groups('test@test.com')

    return groups

You should NOT change the name of custom_get_groups and seahub_custom_functions/__init__.py

Tip

You need to restart seahub so that your changes take effect.

Deploy in DockerDeploy from binary packages

docker compose restart

cd /opt/seafile/seafile-server-latest
./seahub.sh restart

If your changes don't take effect, You may need to delete 'seahub_setting.pyc'. (A cache file)
