Form to edit specific instance of model
I know this question has been asked before but I have read through the answers and none of them sufficed. I am trying to make a job board site, where an employer can sign up and post jobs.

dynamically importing models in django throws models not ready
in my venues app model file I am dynamically adding models I need to do work. from django.apps import apps state = apps.get_model('suitsandtablesadmin', 'State') suitscity = apps.get_model('suitsandtablesadmin','City') suitsneighboorhood = apps.get_model('suitsandtablesadmin', 'Neighborhood') venuetypes = apps.get_model('suitsandtablesadmin', 'VenueTypes') venueseatingtypes = apps.get_model('venueadmin', 'SeatingTypes') costofvenue = apps.get_model('venueadmin', 'VenueCost') venuecusines = apps.get_model('venueadmin', 'Cusines') roomprivacy = apps.get_model('venueadmin', 'Roomprivacy') roomamenities = apps.get_model('suitsandtablesadmin', 'Amenities') I am doing this because a regular import statement will not work. Python says it can find the model, I am guessing because of circular importing. I see from this stackoverflow answer that it may be best to import the entire app into the file but how will that help?

Django OneToOneField on foreign table
I'm trying to setup a new server with foreign tables (using postgres_fdw) that weren't foreign tables previously, and I have some OneToOneFields pointing to these tables. This doesn't work out of the box - OneToOneFields use foreign keys, and postgres_fdw does not support foreign keys for foreign tables. The foreign tables are in a read-only database on the same server. Is there an easy way to get this working? -

Passing parameters from ModalFormView to a form

CAS Server url configuration raising a 403
After my last question I managed to figure out how to setup django-mama-cas and django-cas-ng for the most part. Had to port django-cas-ng to work on Django 1.11 and my setup. Now, I think my MAMA_CAS_SERVICES setting might be wrong for the services url. Lets say I got to seconddomain.com/accounts/login. This sends me to mycasserver.com/cas/login where I can login. Upon logging in there it adds a query to the url but I get a 403 (permission denied) on urls of this form. Example: mycasserver.com/cas/login?next=ticket....... This happens when one domain is still logged in but the other isn't (the one I'm logging into) since I'm not forcing the signout to propagate between the domains. My MAMA_CAS_SERVICES setting: { 'SERVICE': '^https?://mydomain1.herokuapp.com/', 'CALLBACKS': [ 'mama_cas.callbacks.user_name_attributes', ], 'LOGOUT_ALLOW': True, 'LOGOUT_URL': 'https://mycasserver.herokuapp.com/cas/logout', }, { 'SERVICE': '^https?://mydomain2.herokuapp.com/', 'CALLBACKS': [ 'mama_cas.callbacks.user_name_attributes', ], 'LOGOUT_ALLOW': True, 'LOGOUT_URL': 'https://mycasserver.herokuapp.com/cas/logout', }, -

Get the values from one app to another in Django
I am working on creating shopping cart. I am still in learning phase.

Django queryset filter weekday is different in database
I'm using Django 1.10 with Postgres. I have a class defined as : class Availability(models.Model): profile = models.ForeignKey(Profile) date = models.DateField() And I'd like to get all the availabilities which date is a monday. In my database, I have a availibity which date is a monday. I used : Availability.objects.filter(profile=profile, date__week_day=2) as defined in the Django doc, 2 being monday : https://docs.djangoproject.com/en/1.10/ref/models/querysets/#week-day But it returns no objects. I then tried to change the week_day and the queryset returns the right object when I used date__week_day=4. I tried with other week days, and it appears that their is always a gap of 2 weekdays between the query_set and the database. Is there a configuration to set which day should be the start of the week ? -
Django Trunc data to 15 minutes
I am currently using the Truc function of Django to aggregate some data within the day and hour. I would like to do the same but over 15 minutes, instead of an hour or just a minute but I can't figure it out. Here is an example of my current query: data_trunc = data_qs.annotate( start_day=Trunc('date_created', 'minute', output_field=DateTimeField())) .values('start_day', 'content', 'device') The problem lies with the 'minutes' argument that can be passed to Trunc. As far as I get it, there is no choice inbetween 'hour' and 'minutes'. How can I group my data over 15 minutes and have a larger time span for the data grouping ? I know that I could do this by hand afterward but I'd really like to have the database do this for me since there is a large dataset to compute and this way is the most efficient one I have yet. If this is the only way though I am opened to suggestions to the most efficient ways to get around this. Thanks for your help -

Signal Handler Issue
First off I'm using LDAP authentication with Python 3.6 and Django 1.11, if a user is verified with AD it will create the username, password in my User table. Then I have a pre-populated table which is not to be modified or changed called AllEeActive that has a primary key of employee_ntname which I made a OneToOneField using the following class AllEeActive(models.Model): employee_ntname = models.OneToOneField(User, db_column='Employee_NTName',max_length=12) 40 other fields @receiver(post_save, sender=User) def save_user_profile(sender, instance, created, **kwargs): if created: AllEeActive.objects.create(employee_ntname=instance) AllEeActive.objects.get(employee_ntname=instance).save() @receiver(post_save, sender=User) def save_user_profile(sender, instance, created, **kwargs): if created: AllEeActive.objects.create(employee_ntname=instance) AllEeActive.objects.get(employee_ntname=instance).save() class Meta: managed = False def __str__(self): return self.employee_ntname I combined my create and save into one signal call, but for some reason it gives me the error message that accounts.models.DoesNotExist: AllEeActive matching query does not exist.

Connect Django with existing remote MySQL schema
Im trying the get data from an existing remote MySQL table with raw SQL in Django. In other words I do not have to create tables (models in Django) - just read data in a table in a 1st step.

In Django how to get this pandas dataframe to a template?
django newbie question: Documentation with django and pandas focuses on models. I need to understand better how to trace the model, view and template where pandas is involved. Here is an application problem: I am trying to display mobile telephone allowances in an app. For example, each mobile connection has a mandatory tariff and also four optional, value added services ('VAS'). Tariffs cannot be VAS, but you could have the same VAS four times to boost your allowances. There is a single table 'Tariff' for managing the details of all tariffs and VAS. For each call line identifier (mobile phone connection), we need to read the call minutes, data megabytes and text count allowances that sum from the associated tariff and four VAS columns. # models.py class Tariff(models.Model): tariff_name = models.CharField(max_length=200, unique=True, db_index=True) minutes = models.IntegerField(blank=True, null=True,) texts = models.IntegerField(blank=True, null=True,) data = models.FloatField(null=True, default=0) is_tariff_not_VAS = models.BooleanField(default=True) class CallLineIdentifiers(models.Model): mobile_tel_number = models.CharField(max_length=11, blank=False, null=False, db_index=True) tariff = models.ForeignKey(Tariff, related_name = 'tariffName' ) vas_1 = models.CharField(max_length=100, blank=False, null=False, default=0,) vas_2 = models.CharField(max_length=100, blank=False, null=False, default=0,) vas_3 = models.CharField(max_length=100, blank=False, null=False, default=0,) vas_4 = models.CharField(max_length=100, blank=False, null=False, default=0,) So far, so good.
