Using wysiwyg editor in the admin text area
I have bought a licence for the Redactor wysiwyg, and now I want to use it in my admin text area. I have got the javscript and css files to include. But I am not sure how to integrate the Redactor wysiwyg into the django admin text area. I have seen some other plugins also, but they are outdated versions, and I want to use the latest version. How can I use it in my admin? Your guidance will be very much appreciated. Thank you. -

How to configure haystack for elasticsearch 5.0 in django settings?
I just upgraded elasticsearch to 5.0.0 . I have django 1.7.7 and djago-haystack 2.4.1 . In elasticsearch 5.0.0, Authorization header has been added for security purpose. So while making connection to elasticsearch through django, it's throwing error elasticsearch.exceptions.AuthenticationException: TransportError(401, u'security_exception') Where can we add the Authorization field in haystack configuration? -
Migrate existing Django users to OpenLDAP with the same password
I'm using Django's User model as the authentication backend. Now I want to migrate all the users to an OpenLDAP server. I believe if I can make OpenLDAP use the same hashing algorithm and password string format, I can just copy over the password hash from Django, users will just be able to login using the same username and password when I plug in OpenLDAP. My Django app's using PBKDF2 hasing algorithm so what I'm trying to do is to configure OpenLDAP to use PBKDF2 using this module: https://github.com/hamano/openldap-pbkdf2 The password hash in Django will be like: pbkdf2_sha256$12000$MySaltString$somehashstring... I tried many times but couldn't make it work with OpenLDAP. It would be great if you guys could give me some hints. Thanks a lot, Trinh -
Don't apply existing migrations for a model
I need to tell Django not to apply already existing migrations for a model. Is there a way I can achieve it? Why: I have some customizations on top of django.contrib.auth. With those, Group model is left unused. However, migrations for it are included into the auth app. Unlike User, Group is not swappable. -

Wagtail api add fields to pages endpoint
I have been trying to follow the following docs http://docs.wagtail.io/en/v1.6.3/reference/contrib/api/installation.html?highlight=api for my wagtail 1.6.3 instance. It tells me to add a field to the api_fields array in classes that extend page. So I have tried this: class HomePage(HeaderPage): body = RichTextField(blank=True) main_image = models.ForeignKey( 'wagtailimages.Image', null=True, blank=True, on_delete=models.SET_NULL, related_name='+' ) content_panels = HeaderPage.content_panels + [ FieldPanel('body', classname="full"), ImageChooserPanel('main_image') ] test = models.CharField(max_length=20, default="test"); api_fields = ['test', 'body', 'main_image','header_image', 'show_in_menus'] But I am only getting these fields on the detail page and on the /api/v1/pages/ endpoint it only shows the title and meta data field. How can I add more fields that will show on that enpoint -

How to integrate BlurAdmin template with my django project?
Firstly, is it possible to integrate? If it is, can you let me know how to go about it. I am stuck here. I have cloned it to my system following the guidelines provided and it worked. Now I have to integrate this to my django project(Frontend -> AngularJS, Backend -> Python). So, it will be like mostly BlurAdmin for front-end and python for back-end. -
Make a view to update one element in a list in django
I am pretty new to django, I am displaying a list of items in my template and each item has an edit button, when user clicks it, an edit form pops up on the page. I am thinking to do this, on clicking edit, a js function is called that hides the rest of the page and the edit form which was hidden till now is made visible, but my problem is I don't know how should that edit form get information about that item to fill the fields of the form. I can make an edit view that will return a form filled with the information, but how will I call it. Is there any other way except ajax, I tried using ajax, it is not working. -
Why is the database used by Django subqueries not sticky?
I have a concern with django subqueries using the django ORM. When we fetch a queryset or perform a DB operation, I have the option of bypassing all assumptions that django might make for the database that needs to be used by forcing usage of the specific database that I want. b_det = Book.objects.using('some_db').filter(book_name = 'Mark') The above disregards any database routers I might have set and goes straight to 'some_db'. But if my models approximately look like so :- class Author(models.Model): author_name=models.CharField(max_length=255) author_address=models.CharField(max_length=255) class Book(models.Model): book_name=models.CharField(max_length=255) author=models.ForeignKey(Author, null = True) And I fetch a QuerySet representing all books that are called Mark like so:- b_det = Book.objects.using('some_db').filter(book_name = 'Mark') Then later if somewhere in the code I trigger a subquery by doing something like:- if b_det: auth_address = b_det[0].author.author_address Then this does not make use of the original database 'some_db' that I had specified early on for the main query. This again goes through the routers and picks up (possibly) the incorrect database. Why does django do this. IMHO , if I had selected forced usage of database for the original query then even for the subquery the same database needs to be used. Why must the database routers … -
Should I start a new Django app with version 1.8?
I'm about to create a new custom Django app for my organization. (I'm a brand new Django developer; this will be my first one apart from the occasional "Hello world" I've done as a prototype.) I'm on a shared hosting provider, which indicates that for Django applications, we should use Django version 1.8 (even though 1.10 is the current version) because 1.8 is the last version that supports FastCGI. Am I setting myself up for having a worthless app a few years from now once 1.8 is no longer supported? Would one expect that by the time 1.8 is no longer supported, the shared web hosting world will have moved on to WSGI or some form of workaround? Or is that a fundamental impossibility? Will I find in a couple of years that I've developed an application that is unusable on the host I've produced it for? Alternatively, should I be considering some other development tool for the situation I'm in? I'm on a shared host, and I'll be doing a fairly vanilla web front end / database back end style setup. -

Nesting ViewSet routes in DRF
I've created 2 ModelViewSets like so (simplified for demonstration): class SomeBaseViewSet(viewsets.ReadOnlyModelViewSet): serializer_class = SomeEventSerializer permission_classes = (permissions.IsAuthenticated,) def get_queryset(self): return SomeObjects.objects.filter(owner=self.request.user) def get_serializer_context(self): context = super(SomeBaseViewSet, self).get_serializer_context() context.update({ "user": self.request.user, "some_context_key": False }) return context class AdminViewSet(SomeBaseViewSet): # Added in the HasAdminPermission permission_classes = (permissions.IsAuthenticated, HasAdminPermission) # Different queryset filter (overriding `get_queryset` vs setting queryset for standardization) def get_queryset(self): return SomeObjects.objects.all() # The context should have `some_context_key=True`, and `user=request.user` def get_serializer_context(self): context = super(AdminViewSet, self).get_serializer_context() context.update({ "some_context_key": True }) return context My router/url config looks like this router = DefaultRouter() router.register(r'some_view', SomeBaseViewSet, base_name="some_view") urlpatterns += [ url(r'^api/', include(router.urls)), ] If I wanted to route /api/some_view/admin to the AdminViewSet, what's the best way to do that?

Django Many-to-many with extra data
I've read through the the django page on many-to-many relationships, but can't figure out the right way to represent my ERD. I have a table (model) of instruments, and a table (model)of methods (representing work in a real-world laboratory). these need to have a many-to-many relationship, which Django would handle just fine via their models.ManyToManyField attribute. however, I must record a user (model is userProfile which is the validating_user for that relationship, and the timestamp of the validation. I could do it something like this: class Version(models.Model): version_number = models.CharField(max_length=50) cmd_line_script = models.CharField(max_length=250, null=False) SOP = models.TextField(null=False) FK_method = models.ForeignKey(Method, on_delete=models.CASCADE) class Meta: unique_together = ('version_number', 'FK_method') class Instrument(models.Model): serial_number = models.CharField(max_length=50, unique=True) asset_number = models.CharField(max_length=50, unique=True) name = models.CharField(max_length=50) checksum = models.BinaryField FK_instr_type = models.ForeignKey(InstrType, on_delete=models.PROTECT) Instr_Version = models.ManyToManyField( Version, through='Instr_Version', related_name = 'Instr_Version', ) class Instr_Version(models.Model): FK_version = models.ForeignKey(Version, on_delete=models.CASCADE) FK_instrument = models.ForeignKey(Instrument, on_delete=models.CASCADE) validating_user = models.ForeignKey(UserProfile, on_delete=models.PROTECT) timestamp = models.DateField(auto_now_add=True) class Meta: unique_together = ('FK_version', 'FK_instrument') which would look pretty much like a normal SQL setup, but I figure I should try to use the relationships in the most Django way possible. this is particularly relevant as I'm trying so set up serializers via the dangoRestFramework, and …
