Conditionally require password when creating user in Django Admin page
I am using LDAP for authentication in my Django app so when adding a user in the admin page I don't need to set a password since the user will be authenticated against the LDAP backend. I'd like to modify the 'Add user' page in the admin views to have a boolean selector to identify when I am trying to add an LDAP user so that the password field is not required. I'd like to retain the option of supplying a password in case I need to add a local user that authenticates against Django's backend. Here is what I've cobbled together so far: models.py Modified the save method so that the user gets populated in the CustomUser model if isLdap is True. class CustomUser(AbstractUser): pass isLdap = models.BooleanField(default=False) def save(self, *args, **kwargs): if self.isLdap: user = LDAPBackend().populate_user(self.username) else: super().save(*args, **kwargs) def __str__(self): return self.username admin.py I successfully added a check box to identify if the new user is an LDAP user but the value isn't being saved to the CustomUser model and I need to change save_model so it saves the actual password if it is valid otherwise set_unusable_password(). class CustomUserAdmin(UserAdmin): add_form = CustomUserCreationForm add_fieldsets = ( (None, { … -

How to encrypt or Obfuscate REST API URL in Django
Hello Django REST API Experts, We are building University Course portals where app offers various user types like Professor, Students and Admins using DJANGO/REACT. We are using REST API to connect between backend and frontend. So, far we are able to perform some basic operation and it really works great. However now I need help from this group to do following: When students enrolled in course it generates an acknowledge document stating course description, and its prerequisite which needs to get signed by students to ensure student acknowledge they fulfill these requirements. In order to do this we have following: Model for each course which contains the Content, Description and Prerequisite for each course. StudentCourseAck Model which has FK to Course, Signed Boolean field, Binary field to store signed doc. User flow: Student logins to portal, Select the Course, which generate StudentCourseAck entry. Let Student review document and signed the document (on client side using sign pad). The Signature gets stored in PDF (as binary field). So far so good… Now we want to enhance the featureset which allows admin to email student the link of studentcouseack document incase its not signed before course start. Also this link should only … -
For a query set of a single element, indexing 0th element of a (query_set[0]) and and query_set.first() give different values - Django 2.2.7

Django - How to iterate comlicated JSON object?
I have json object like [{'Group Name': 'asdfasdf', 'inputs': [{'DataType': 'data2', 'DataName': 'asdfasdf'}, {'DataType': 'data1', 'DataName': 'asdfasd'}, {'DataType': 'data2', 'DataName': 'asdfas'}]}, {'Group Name': 'asdfasdf', 'inputs': [{'DataType': '', 'DataName': 'asdfasdf'}]}] Data type and data name fields can be multiple in one group name. Group name can be multiple with at least one data type and data name field. This multiplication is dynamical due to user's choice. However, I am new in python and django. I didn't understand loop mechanism of them. How can I build a loop mechanism for group name count and data inputs count? -

Creating a simple form using django and searching a SQL database
I am trying to create a form that will allow users to search a database. The intended language is django. I have created the backend database for a simple student schema, and I will eventually have a stored procedure that takes different parameters, if any of the parameters are provided a search will be done on the database and results returned. For the purposes of this exercise, a simple table will also suffice for searching. I did some reading up and I have been able to come up with the below, however it feels like a log way from what I am trying to achieve, a prototype can be seen below of what I am trying to achieve. The back end database is SQL server, I have configured the database with django and created the table/tables. I would also like to understand how to play with stylesheets to create nice looking yet simple pages. On my views.py.

Accessing the values of a ManyToManyField in Django

Django dynamic installed apps
