Wagtail 2.2.2, django 2.1.1 compatibility issues
Wagtail github site says that wagtail is compatible with django 2.1.x. I am trying to setup a project with pipenv. When I install wagtail via pipenv it installs django version 2.0.8 If I try to update django to 2.1.1 console gives: Your dependencies could not be resolved. You likely have a mismatch in your sub-dependencies. Could not find a version that matches django<2.1,==2.1.1,>=1.11 Besides the error it installs django 2.1.1. But then when I runserver... I get error: AttributeError: module 'django.contrib.auth.views' has no attribute 'login' So is wagtail 2.2.2 compatible with django 2.1.x ? -
How can I dynamically change the storage of Django FileField()?
Basically I got the following model where some uploaded documents will be public and some others private. To decide when the doc is private or not, when creating the instance, I set the field is_public=True/False, then I will be able to choose the right direction within the AWS S3 bucket. So I want to be able to change the storage to PrivateMediaStorage() when is_public=False from my_project.storage_backends import PrivateMediaStorage class Document(models.Model): file = models.FileField(upload_to="uploaded_documents/%d-%m-%Y") # file = models.FileField(upload_to="uploaded_documents/%d-%m-%Y", # storage=PrivateMediaStorage()) uploaded_by = models.ForeignKey(UserProfile,blank=True,null=True) nb_download = models.IntegerField(default=0) is_public = models.BooleanField(default=False) Here is the storage class in case it's important. from storages.backends.s3boto3 import S3Boto3Storage from django.conf import settings class PrivateMediaStorage(S3Boto3Storage): location = settings.AWS_PRIVATE_MEDIA_LOCATION default_acl = 'private' file_overwrite = False custom_domain = False -

Django - how to create membership models with foreign keys and manytomanyfield
I am trying to create a django membership models with 2 model classes: Target and Group. I want to have targets attributable to certain groups, but also to be able to query which targets are in which group. This is what I have so far and I am able to see that "targets" is a field of Group but it shows up as empty in the query set when I access Group.objects.get(pk=1) through a variable. I also want both groups and targets to be attributable to certain users. Here are my models, what am I doing wrong? I've tried doing this a few different ways so far: class Target(models.Model): first_name = models.CharField(max_length=50, default='Target First name') last_name = models.CharField(max_length=50, default='Target last name') email = models.EmailField(max_length=100, default='email@example.com') user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.DO_NOTHING) date_time = models.DateTimeField(auto_now=True) group = models.ForeignKey(Group, on_delete=models.DO_NOTHING, null=True, blank=True) def __str__(self): return self.email def __unicode__(self): return self.email class Group(models.Model): group_id = models.IntegerField(primary_key=True) name = models.CharField(max_length=50, default='Group name') created_date = models.DateTimeField(auto_now=True) modified_date = models.DateTimeField(null=True, blank=True) targets = models.ManyToManyField(Target, related_name='targets', blank=True, null=True) user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.DO_NOTHING) def __str__(self): return self.name def __unicode__(self): return self.name -
Using django-filter with django-tables2, how do I annotate a queryset?
I am using django-filter and django-tables2 to pull data from a SQLite3 database. The database has 15+ fields of sales order information were they may be multiple lines (Line field) per sales order. I would like to render a table that does the equivalent of 'Group By' sales order and sum the ExtAmount field. I know I should use the annotate function but I am unsure where to implement this with django-filter/django-tables2. In SQL I used the below to get what I need: SELECT SalesOrder, Customer, Count(Line) AS Lines, Round(Sum(ExtAmount), 2) AS Amount FROM backlog_backlogData GROUP BY SalesOrder Order By Sum(ExtAmount) DESC limit 100 As of now, the view renders the three fields from tables.py but without grouping SalesOrder. Which is great, but I can't seem to find traction of where I need to annotate. I've read through the docs and searched through other questions and I just can't seem to understand how to use django-filter/django-table2. The only place I have found 'annotate' referenced in the django-filter docs is with the ModelMultipleChoiceFilter filter reference. Any help would be great! #models.py from django.db import models class backlogData(models.Model): Shipto = models.IntegerField() Customer = models.CharField(max_length=200) City = models.CharField(max_length=200, null=True) ST = models.CharField(max_length=200, null=True) … -
Static files in Django 1.8
My static files are inside the main django folder (BASE_DIR). It works fine, until I turn off the DEBUG. The error occurs because the 'static' function returns empty if the DEBUG is off.

Thanks any help. urls.py urlpatterns = [ url(r'^$', redirect), url(r'^webContextRoot/', include(base)), ] + static(settings.STATIC_URL, document_root=settings.STATIC_ROOT) settings.py # SECURITY WARNING: don't run with debug turned on in production!

Django choking on special character in model name
I'm using a legacy MSSQL database with my Django application, and one of the column names contains a "%". As a result, Django is looking for a format variable whenever the model is called. I've isolated the issue to know it breaks on this field within my model: fg_field = models.DecimalField(db_column="FG%", max_digits=15... And the error message I get is: sql = sql % tuple('?' * len(params)) TypeError: not enough arguments for format string When I note out this field in the model, the application works fine... so I know it has to do with this naming convention. Can I do anything on the Django side to stop this from happening? -
Where to insert data into a django form before validation?
I have a modelForm created from a Model: class Client(models.Model): name = models.CharField(max_length=30) domain_url = models.CharField(max_length=128, unique=True) schema_name = models.CharField(max_length=63, unique=True, validators=[_check_schema_name]) I am not showing the schema_name for editing, as I want this to be automatically generated somewhere between form submission and validation. class SetupForm(forms.ModelForm): '''Setup form for the new instance domain_url and schema_name are charfield ''' class Meta: model = Client fields = ['name', 'domain_url', ] I want to modify the domain_url and create a schema_name from it. I still want the regular form validations to run though. So where can I add the schema_name to the data for cleaning? -
Prepopulating fields of user edit form (also: passing {{user}} into a javascript function?)
Basically, I'm trying to make an edit profile modal with fields that are already prepopulated by the user's original data. I passed django models into my javascript files by using these brackets {{}} but it doesn't seem to work for {{user}} (as in request.user). This is what I did for simple fields: <div class="field"> <label>Email</label> <input value={{user.email}} type="email" name="email" placeholder="Email"> </div> {{user.email}} successfully is set as the default value for the input. Is there a different way to prepopulate fields? If there is, let me know and I might not have to deal with this next situation. My naive solution works for text fields but if I have a multiselect like: <div class="field"> <label>Native Language</label> <select name="nativelanguage" id="nativedrop" class="ui fluid search selection dropdown"> <option value="">Language</option> <option value="English">English</option> <option value="Spanish">Spanish</option> <option value="French">French</option> </select> </div> my solution no longer works. I want to pass {{ user }} into a javascript function like myFunction({{ user }}) but it seems that this is not possible. Could anyone give me advice on how to prepopulate fields or fix the second issue below? Thanks! -
Kerberos Double Hop Delegation with Django on IIS
I need to pass the credentials (Integrated Windows Authentication) from a django website on IIS onto a backend SQL server so that it runs under the proper user context. This is how my setup looks so far: Running SQL Server on sql_sever.domain.com under a service account domain\svc_sqlserver Running Django website on app_server.domain.com using IIS under a service account domain\svc_appserver with Windows authentication and ASP.Net Impersonation (Providers is set to Negotiate:Kerberos -> Negotiate -> NTLM ) with useAppPoolCredentials=True Connecting to SQL server from django using Windows authentication by setting Trusted_Connection=yes in the connection Configured SPNs for Kerberos authentication both for SQL Server and IIS as follows setspn -a HTTP/app_server domain\svc_appserver setspn -a HTTP/app_server.domain.com domain\svc_appserver setspn -a MSSQLSvc/sql_server.domain.com:PORT domain\svc_sqlserver setspn -a MSSQLSvc/sql_server.domain.com:INSTANCE domain\svc_sqlserver setspn -a MSSQLSvc/sql_server.domain.com domain\svc_sqlserver Trusted both svc_sqlserver and svc_appserver for delegation to MSSQLSvc services and additionally for domain\svc_appserver I added HTTP services too (from the above list) Result: Kerberos authentication works on SQL Server. Confirmed by looking at auth scheme of connected users Kerberos authentication works on Django website. Confirmed by inspecting WWW-Authenticate response header and Authorization request header (Negotiate is being correctly used) Sql server runs only under the context of domain\svc_appserver when it should be running under … -

Django SQLite3 to PostgreSQL - duplicate key error on OnetoOne User Model
I'm having some trouble with migrating from SQLite3 to Postgres on Django. Essentially I'm following this thread (Django: What are the best practices to migrate a project from sqlite to PostgreSQL). There's been a similar error that I've used the TRUNCATE command on and got past, but now I'm hitting a duplicate key error for my own model. The model client is a OnetoOne relationship with Django's built in user. It just asks for a few additional details like business type and join date. And the migration is coming up with an error. The client, primary key 1 is my superuser with code: user = models.OneToOneField(User, on_delete=models.SET_NULL, null=True, blank=True) And I'm getting this error: django.db.utils.IntegrityError: Problem installing fixture 'C:\Users\*******\dump.json': Could not load clauses.Client(pk=1): duplicate key value violates unique constraint "clauses_client_clientusername_id_******_uniq" Could someone point me the right way?

How To Define A Docusign Event/Envelope Notification Python API
For my company, I've been creating a webapp that will make the creation and signing of a letter of agency easier. I am almost completely finished with it. However, the only issue that I am experiencing is that, after the envelope is created, the email is never received by the recipient asking for the signature. I have checked under docusign's manage tab, and the envelope is listed there, with the correct recipient email address. I've attempted to resend it multiple times, and the email is still never received, although it's listed as being sent. The code that I'm using is as follows: username = "myDocusignUsername" integrator_key = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" base_url = "https://demo.docusign.net/restapi" oauth_base_url = "account-d.docusign.com" redirect_uri = "http://myredirecturi" private_key_filename = "path/to/pKey.txt" user_id = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" client_user_id = 'recipient@gmail.com' # Add a recipient to sign the document signer = docusign.Signer() signer.email = "recipient@gmail.com" signer.name = "Recipient Name" signer.recipient_id = '1' signer.client_user_id = client_user_id sign_here = docusign.SignHere() sign_here.document_id = '1' sign_here.recipient_id = '1' sign_here.anchor_case_sensitive = 'true' sign_here.anchor_horizontal_alignment = 'left' sign_here.anchor_ignore_if_not_present = 'false' sign_here.anchor_match_whole_word = 'true' sign_here.anchor_string = 'Signature of individual authorized to act on behalf of customer:' sign_here.anchor_units = 'cms' sign_here.anchor_x_offset = '0' sign_here.anchor_y_offset = '0' sign_here.tab_label = 'sign_here' sign_here.IgnoreIfNotPresent = True; tabs = … -

Django m2m field remove method not working
