Django TinyMCE ImageLists when using HTMLField
I'm struggling to get the imagelists and linklists working in TinyMCE on Django when using a HTMLField. The documentation says: somefield = forms.CharField(widget=TinyMCE(mce_attrs={'external_link_list_url': reverse('someviewname')}) But I'm using the HTMLField so have to approach it differently. I've looked at How to increase width of editor in django-tinymce HTMLField? and am getting the same init error as suggested. Has anyone been successful with this? -

How to override value of read-only field in view depending on query param?
I have this model that has a read-only field where I calculate some property. class BlastEvent(Event): tonnes = models.FloatField() blast_type = models.ForeignKey(BlastType) @property def size(self): return self.tonnes / BlastEvent.objects.all().aggregate(Max('tonnes'))['tonnes__max'] This is my serializer: class BlastEventSerializer(serializers.HyperlinkedModelSerializer): size = serializers.ReadOnlyField() included_serializers = {'blast_type': BlastTypeSerializer} blast_type = ResourceRelatedField( queryset=BlastType.objects, related_link_view_name='blastevent-blasttype-list', related_link_url_kwarg='pk', self_link_view_name='blastevent-relationships' ) class Meta: model = BlastEvent fields = ('url', 'id', 'tonnes', 'blast_type', 'size') class JSONAPIMeta: included_resources = ['blast_type'] And this is my view: class BlastEventViewSet(EventViewSet): queryset = BlastEvent.objects.all() serializer_class = BlastEventSerializer Now I need to re-calculate and override this read-only field depending on query parameter. I'm not sure where is the proper place to do it. I tried to do it in get_queryset() method of my view like this: class BlastEventViewSet(EventViewSet): queryset = BlastEvent.objects.all() serializer_class = BlastEventSerializer def get_queryset(self): queryset = self.queryset instrument_id = self.request.GET.get('instrument_id') if instrument_id: for e in queryset: e.size = e.size + Instrument.objects.get(pk=instrument_id).distance return queryset but it doesn't work.

Django admin panel - Inlines do not show on production server, but do show on local server
Recently I started using the inline functionality for Django admin panels. It just makes it so much easier to add objects. The picture below shows that it allows an admin to add a module while creating a training: Django admin panel with working inlines However, once I push the code to production, the inlines functionality stops working. It simply does not show. My server makes use of Gunicorn and Nginx. Initially I thought that Nginx does not know where to find the static files, but this is not the problem. However, if I run a server via Django with python manage.py runserver 0.0.0.0:8001, then it does work. Additionally, if I run the server via Gunicorn by binding it to 0.0.0.0:8001, then it works as well. This makes me think that the problem is Nginx, but I have no idea where to search. Please help me out :). Kind regards, Nicky -
Django Admin ChoiceField and Button submit to custom admin site (A form in a form)
I would like to generate a contract (as a printable html file) out of the change form of a customer (defined as model) in the django.contrib.admin interface. This contract should be displayed as html file in a different view. So my idea is to have a Dropdown (forms.ChoiceField) with a Submit button in the admin form of a model. If you click on the button then a custom admin site (or HttpResponse, doesn't matter now) will be opened depending on the selected choice. So for example, if I select "Contract one" and click on the button, a page with the template from contract one will be displayed in a new page. But all this should be inside the change_forms.html in a seperate fieldset. What I have so far: A ModelForm with an extra field 'contract' and rendering the button with url reverse as forced html output. admin.py class AnimalAdmin(admin.ModelAdmin): form = AnimalForm list_display = ( 'name', 'customer', ) ordering = ('name',) fieldsets = ( (None, { 'fields': ( ('name', 'species'), ('customer', 'breed'), ) }), (_('Vertrag'), { 'fields': ( ('contract'), ('animal_contract'), ) }), ) readonly_fields = ('animal_contract',) def process_contract(self, request, animal_id, *args, **kwargs): return self.process_action( request=request, animal_id=animal_id, action_title='Contract Generation', ) def … -
What's difference between url() and reverse() methods in Django?
I have some method, and after successful form submitting i need to make some redirect to another page. How can i do this? return HttpResponseRedirect(reverse('goods:results', args=(item.id,))) or return HttpResponseRedirect(url('polls:results', question.id))? What's the main difference by using these two ways? -
Managing state and transitions
I need to implement a standard workflow with three linear steps to handle, i.e. Select Plan & Preference, Personal Information, and Review & Payment. I know three available workflows with python3 and Django, but I think it is overkill for what I am going to do. Select Plan & Preferences: A client may choose one plan as well as some craft products. Personal Information: A client will fill fields related to where he lives, phone number, first name, last name, email, ... Review & Payment : Create an account if necessary, Review his/her order and make the payment related to the current order. Availabe Workflow - With Python 3 Maybe the solution is to implement a custom workflow, but I am a bit confused how to do it. I need a user follows some views step by step. How to check what is the next view that the user should go? Could someone explain to me roughly how can I do it? Does the following website is a great solution for that little workflow? P.S. I am working with Django 1.11 and python 3.4. -

django celery error "Apps aren't loaded yet" All recommended fixes I've tried has failed - I believe I have settings configured incorrectly somewhere
My goal is to use celery to use celery to automatically run script on my site each day. I followed the instructions for first steps with Django here. After I have all of my setting configured, I use celery -A project worker --loglevel=info and the server seems to start fine. When I attempt to import the tasks app it can't find the module, it says it doesn't exist, but it works if I explicitly call folder.tasks. If I call function.delay() I get the following error: raise AppRegistryNotReady("Apps aren't loaded yet.") django.core.exceptions.AppRegistryNotReady: Apps aren't loaded yet. I do a few searches and try adding a recommendation of using Django-Q. After I put it at the bottom of installed apps and attempt to python manage.py migrate celery, I get the same AppRegistryNotReady error as before but when I attempt to start celery.

The fun of django form datetime pickers
So I've explored several ways of trying to add a date time picker to my django forms. It's been ugly. I've found one that I've gotten to work well here. It looks good and works...sort of. The new problem becomes I'm rendering my datetime fields in a formset, so I need to add an index value to the id field of the element. That means something like clock_in = forms.DateTimeField(widget=DateTimePicker(attrs={'class': 'form-control', 'id': 'datetimepicker1'})) will not work. datetimepicker# needs to be indexed for each element the formset generates. Can I even do that? If so, how. Are there easier\better ways to graphically select a datetime for input (like the django admin)? -
Using Pika with Django (Event-based microservice using django rest framework)
anyone here has experience implementing pika with Django? I am basically running an event-based microservice using django rest framework. And using RabbitMQ as the message bus. I know the default library to use in this case would be Celery, but I am looking for a lighter version where I can just implement a simple pub / sub on the messages. Has anyone implemented such a service using pika before? My question is more how do you spawn pika as a separate process together with Django? Or is there a more elegant solution out there? Thanks in advance. -

So I am trying to modify a user in my active directory. As of now I can log in as an AD-user but when I try to edit my profile, it does not implement in the AD. I made a connection with a user that has reading an writting permissions. AUTH_LDAP_SERVER_URI = "ldap://192.168.1.12" AUTH_LDAP_BIND_DN = "user" AUTH_LDAP_BIND_PASSWORD = "password" AUTH_LDAP_CONNECTION_OPTIONS = { ldap.OPT_DEBUG_LEVEL: 1, ldap.OPT_REFERRALS: 0 } AUTH_LDAP_USER_SEARCH = LDAPSearch("DC=sb,DC=ch", ldap.SCOPE_SUBTREE, "(sAMAccountName=%(user)s)") # Set up the basic group parameters.
