Django LDAP Authentication Group Membership problem
I am trying to implement LDAP authentication for a Django project. There are three different groups which are allowed to log in. user1 is a member of grp1 and user3 is a member of grp3. So they are supposed to be login but while user1 can log in user3 can not!. LDAP directory has Posix standards. Here is the configuration: from django_auth_ldap.config import LDAPSearch, LDAPGroupQuery, PosixGroupType AUTH_LDAP_USER_SEARCH = LDAPSearch( 'cn=Users,dc=company,dc=com', ldap.SCOPE_SUBTREE, '(uid=%(user)s)', ) AUTH_LDAP_GROUP_SEARCH = LDAPSearch( 'cn=Groups,dc=company,dc=com', ldap.SCOPE_SUBTREE, '(objectClass=posixGroup)', ) AUTH_LDAP_GROUP_TYPE = PosixGroupType() AUTH_LDAP_REQUIRE_GROUP = ( LDAPGroupQuery('cn=grp1,cn=Groups,dc=company,dc=com') | LDAPGroupQuery('cn=grp2,cn=Groups,dc=company,dc=com') | LDAPGroupQuery('cn=grp3,cn=Groups,dc=company,dc=com') ) AUTH_LDAP_USER_ATTR_MAP = { 'first_name': 'givenName', 'last_name': 'sn', 'email': 'mail', } AUTH_LDAP_USER_FLAGS_BY_GROUP = { 'is_superuser': 'cn=grp1,cn=Groups,dc=company,dc=com', 'is_active': ( LDAPGroupQuery('cn=grp1,cn=Groups,dc=company,dc=com') | LDAPGroupQuery('cn=grp2,cn=Groups,dc=company,dc=com') | LDAPGroupQuery('cn=grp3,cn=Groups,dc=company,dc=com') ), } Debug output is here: search_s('cn=Users,dc=company,dc=com', 2, '(uid=%(user)s)') returned 1 objects: cn=user3,cn=users,dc=company,dc=com DEBUG 2019-09-21 08:09:13,193 config 378 140589423471392 search_s('cn=Users,dc=company,dc=com', 2, '(uid=%(user)s)') returned 1 objects: cn=user3,cn=users,dc=company,dc=com cn=user3,cn=users,dc=company,dc=com is not a member of cn=grp1,cn=groups,dc=company,dc=com DEBUG 2019-09-21 08:09:13,253 backend 378 140589423471392 cn=user3,cn=users,dc=company,dc=com is not a member of cn=grp1,cn=groups,dc=company,dc=com Caught LDAPError while authenticating user3: NO_SUCH_OBJECT({'desc': 'No such object', 'matched': 'cn=Groups,dc=company,dc=com'},) WARNING 2019-09-21 08:09:13,257 backend 378 140589423471392 Caught LDAPError while authenticating user3: NO_SUCH_OBJECT({'desc': 'No such object', 'matched': 'cn=Groups,dc=company,dc=com'},) search_s('cn=user1,cn=users,dc=company,dc=com', 0, '(objectClass=*)') returned 1 objects: cn=user1,cn=users,dc=company,dc=com DEBUG 2019-09-21 08:44:14,586 config 405 … -

Systemctl enabled service does not load at boot

Setup of the Divio CMS Repositories

How to create a association with a model in the creation of the object?
I would like to know how can I create an other model instance just after having saved the currently model. I'm changing the original context here to post the question, but let's say I have the models above: class Owner(models.Model): name = models.CharField() points = models.IntegerField() class OwnerCars(models.Model): owner = models.ForeignKey(Owner, unique=True) total = models.IntegerField() cars = models.ManyToManyField(Cars) I would like to create the OwnerCars instance just after I have created a Owner instance, it will initialize the OwnerCars with total = 0 and also a empty list of cars. That total is going to be the sum value of all his cars when it get added. If I create a Owner object and right after that make a GET request to OwnerCars it will say that OwnerCars doesn't exist yet :(. When the person create an Owner profile, I need to have that other model to show info for the person in the screen, that's why I need that instance created. BUT..... If anyone got a better idea, I'm open for it, I know it looks like poor design, and maybe that's the problem. -

Save a new file in the client machine directory which is selected by a user
I am working on a project(a web application that runs only on local) where a person has to select a folder and certain files are saved in the same folder based on images analysis in the same folder. I thought it would be great if I use web application than a desktop application. I used Django and used webkitdirectory mozdirectory to select a folder in HTML part. Now I need full path of the machine from which user selects the directory( to save some files in the same path). The problem is browsers have a security feature that prevents JavaScript from knowing your file's local full path. Any way I can save new file in the same folder user selects or I have to switch to desktop application like PyQT for it? -

How to create an authentication system in django for a SQLServer database?
I am recently working in a django project with a SQLServer database. I already connected the database with SQLServer, and I want to make an authentication system for a table I have in that database. I know django comes with a built-in authentication system, but there is no way to tell django to use a specific table in the database to make the authentication, it just seems to look for users in the default admin page. Is there any way for django to look for data inside a specific table in a SQLServer database and validate the information put by an user? -

Django How to retrieve datetime object with timezone from database
I am having a difficult time with all the mumbo-jungo timezone UTC thing in python. In a django form, I create a zumba class(zumba app for a friend) and select the date and time of the class. Say I create the class for September 19, 8pm, and I am in the America/New York zone, so -4h. In the Posgres database, the entry will be 2019-09-20 00:00:00+00 Django shows it correctly in the view, as it can deal with timezone, but when I retrieve the date object afterwards in the code, I always get as if the class is happening on the 20th at midnight. The timezone offset is not taken into account. Here is the database request to retrieve the zumbaclass object. this_class = zumbaClass.objects.get(id=class_id) if I do print(this_class.date.date()) I get 2019-09-20 00:00:00+00:00 Is there a way to get the time taking the timezone into account correctly? -

Reverse back Postgres field type when migrations were applied in Django
I pulled the new code from GitHub and my colleagues changed the type of a field in a Django model from TextField to JSONField. After running python manage.py makemigrations and python manage.py migrate the type of the field was changed in the database (I suppose). I needed to reverse back to previous migration and somehow the type of the field was not reversed. How could I fix the issue? Why reversing back migration does not revert back the field type?
