Passing field from extended user model to template in Django
I am having an issue passing a field from an extended user model to a template in Django. I defined the extended user fields in a model in a new app called user_management: #user_management/models.py from __future__ import unicode_literals from django.db import models from django.contrib.auth.models import User class lab_user(models.Model): user = models.OneToOneField(User) personal_order_list_url = models.URLField("Personal order list URL", max_length=255, blank=False, unique=True) abbreviation_code = models.CharField("Abbreviation code", max_length=3, blank=False, unique=True) def save(self, force_insert=False, force_update=False): self.personal_order_list_url = self.personal_order_list_url.lower() self.abbreviation_code = self.abbreviation_code.upper() super(lab_user, self).save(force_insert, force_update) I then registered the new fields in admin.py: #user_management/admin.py from __future__ import unicode_literals from django.contrib import admin from django.contrib.auth.admin import UserAdmin as BaseUserAdmin from django.contrib.auth.models import User from .models import lab_user class lab_user_inline(admin.StackedInline): model = lab_user can_delete = False verbose_name_plural = 'Additional Fields' class UserAdmin(BaseUserAdmin): inlines = (lab_user_inline, ) admin.site.unregister(User) admin.site.register(User, UserAdmin) I can see the new fields in "Authentication and Authorization", which I guess means I've done everything "right". When I try to call fields from a template using {{ request.user.x }} where x could be first_name, personal_order_list_url or abbreviation_code, I can retrieve the desired value for first_name and personal_order_list_url, but not for abbreviation_code. If request.user.personal_order_list_url works, request.user.abbreviation_code should work too, shouldn't it? -

Django : AttributeError: 'str' object has no attribute 'strftime'
This is my code: signals.py from record.models import Record person1Age = record.person1Age person1AgeFormat = person1Age.strftime('%d-%m-%Y') print(person1AgeFormat) Result in Django Console: person1AgeFormat = person1Age.strftime('%d-%m-%Y') AttributeError: 'str' object has no attribute 'strftime' The same code works fine in the python3 shell. This problem only occurs in my Django Signal. Should I import something else specific to Django? -
Django :There is no unique constraint matching given keys for referenced table"
There are countless questions related to this error, but after over a month I've still not been able to solve this problem, since in my setup there is in fact a unique constraint. I have already asked this question before, but the answer was to add a unique field to my model which IS already present. I'm running an older django version, 1.7.11, and circumstances do not allow me to upgrade. I have a Photo class, which contains multiple foreign keys to other classes. class Photo(UserBase): """ Photograph """ scene_category = models.ForeignKey( SceneCategory, related_name='photos', null=True, blank=True) artist = models.ForeignKey( Artist, related_name='photos', null=True, blank=True) gallery = models.ForeignKey( Gallery, related_name='photos', null=True, blank=True) The inheritance for UserBase class UserBase(ModelBase): #: User that created this object user = models.ForeignKey(UserProfile) class Meta: abstract = True ordering = ['-id'] class ModelBase(EmptyModelBase): """ Base class of all models, with an 'added' field """ added = models.DateTimeField(default=now) class Meta: abstract = True ordering = ['-id'] class EmptyModelBase(models.Model): """ Base class of all models, with no fields """ def get_entry_dict(self): return {'id': self.id} def get_entry_attr(self): ct = ContentType.objects.get_for_model(self) return 'data-model="%s/%s" data-id="%s"' % ( ct.app_label, ct.model, self.id) def get_entry_id(self): ct = ContentType.objects.get_for_model(self) return '%s.%s.%s' % (ct.app_label, ct.model, self.id) class Meta: … -

Django rest framework combine/nested serializer
I have 2 table, appointment and schedule. schedule has these field: scheduleid, title, 'starttime', 'endtime', 'date' appointment has these field: id, scheduleid, clinicid, 'time', 'queueNo', 'date' schedule starttime is = appointment time. So is the date When ever a user create a Appointment, it will also create a schedule as u can see on above. I know how to make a nested serializer but what i do not know is. If a schedule hasn't been created, what do i insert the scheduleid in the appointment table. Reason is because, create appointment first, how to create so that in appointment django know how to create a scheduleid for it ? -
Django Admin prefetch not working - duplicating queries ~1000 times

How to prevent a site from allowing its users to provide their own templates
I am developing a web app and in the Django documentation I read this: The template system isn’t safe against untrusted template authors. For example, a site shouldn’t allow its users to provide their own templates. Given the fact that I won't be allowing the end-user to upload any code, I reckon that the above would only be possible if the user would somehow gain access to the server and upload his (malicious) templates or by an XSS attack. Is there something else I am missing here and should be aware of? Are there any additional measures (except for securing my server and looking out for XSS attacks) I must take in order to prevent this from happening? -
Django - django-autocomplet-light fields does not display with gunicorn

One model interface to read/write to multiple tables Django
I've the following models in Django. class User(models.Model): name = models.CharField(max_length=50) ... ... class UserInformation(models.Model): user = models.ForeignKey(User) key = models.CharField(max_length=250) value = models.TextField() ... ... class UserAddress(models.Model): user = models.ForeignKey(User) address = models.TextField(null=True) city = models.CharField(max_length=200) ... ... Basically I want to create an interface for User through which I can route read and write operations to UserInformation and UserAddress. user = User.objects.get(id=1) Ex - If someone wants to get all addresses of a user. user.get_information('address') --> This will in turn search UserAddress table and return a list of addresses. Ex - If someone wants to get the current age of a user. user.get_information('age') --> This will in turn search UserInformation table with key=age and return the value. Similarly given a key I want to write data through the interface. Ex - Insert age of a user. user = User.objects.get(id=1) user.update_information('age', value=30) --> This will in turn insert a row in UserInformation table with key=age and value=30. Problems: I'm planning to create another table TableKeyMapping to keep the mapping of keys to table names. Such as if key_name=age, table_name=UserInformation. If key_name=address, then table_name=UserAddress. What should I save in table_name..the model name UserAddress or the complete path including the the … -

How to pass variable value from one view function to another one?

Django url not resolving in similar case to working one
I know this has been asked a lot but I can't find any answers that are general enough to learn something from them. I setup a Django project for the first time but am a little confused as I have 2 forms on 1 page and they both submit to a different view ('tick' and 'bestel') it does everything it is supposed to do under 'bestel' but then I submit to tick it gives me this error: Using the URLconf defined in Que.urls, Django tried these URL patterns, in this order: 1. [name='index'] 2. signup/ [name='signup'] 3. <int:user_id>/ [name='user'] 4. <int:user_id>/bestel [name='bestel'] 5. <int:user-id>/tick [name='tick'] 6. admin/ The current path, 11/tick, didn't match any of these. where can I be going wrong in this? -
Wagtail: How to filter text in streamfield within model.py
I would like to write a filter which replaces some $variables$ in my streamfield text. What is the best way to do this in my "Page" model? I tried the following but it is sometimes not working if I save my model as draft and publish it afterwards.

How to use PostgreSQL ArrayAgg function on a grouped by query set in Django ORM?

postgresql - django.db.utils.OperationalError: could not connect to server: Connection refused
Is the server running on host "host_name" (XX.XX.XX.XX) and accepting TCP/IP connections on port 5432? typical error message while trying to set up db server. But I just cannot fix it. my django db settings: DATABASES = { 'default': { 'ENGINE': 'django.db.backends.postgresql', 'NAME': 'db_name', 'USER': 'db_user', 'PASSWORD': 'db_pwd', 'HOST': 'host_name', 'PORT': '5432', } } I added to pg_hba.conf host all all 0.0.0.0/0 md5 host all all ::/0 md5 I replaced in postgresql.conf: listen_addresses = 'localhost' to listen_addresses = '*' and did postgresql restart: /etc/init.d/postgresql stop /etc/init.d/postgresql start but still getting the same error. What interesting is: I can ping XX.XX.XX.XX from outside and it works. but I cannot telnet: telnet XX.XX.XX.XX Trying XX.XX.XX.XX... telnet: connect to address XX.XX.XX.XX: Connection refused telnet: Unable to connect to remote host If I telnet the port 22 from outside, it works: telnet XX.XX.XX.XX 22 Trying XX.XX.XX.XX... Connected to server_name. Escape character is '^]'. SSH-2.0-OpenSSH_6.7p1 Debian-5+deb8u3 If I telnet the port 5432 from inside the db server, I get this: telnet XX.XX.XX.XX 5432 Trying XX.XX.XX.XX... Connected to XX.XX.XX.XX. Escape character is '^]'. same port from outside: telnet XX.XX.XX.XX 5432 Trying XX.XX.XX.XX... telnet: connect to address XX.XX.XX.XX: Connection refused telnet: Unable to connect to remote host …
