Posting to django from chrome extension won't set the attributes that are pass into the post
I am working on making a chrome extension that stores info from pages you are on and then posts them to my Django backend. I am having a problem with my post, the post makes it to the backend but it does not have any of the attributes that i give it. Here is my post request: I know that my post is making it to the backend here is an example of what the data looks like in my backend: as you can see all the attributes are being set as unknown. In my models.py I am setting them to unknown if no attributes are present so I believe that the post is not working right. I think that maybe my json is not formatted right and that is why it is not taking the attributes but I do not know what the correct format is. any help would be much appreciated. thanks in advance! -
Django - FileField model object - ValueError when saving a many-to-many an instance with a many-to-many relationship
I am trying to save an instance in a model called Document which has a many to many relationship with a project it refers to. Model class for Document is reported as follows: class Document(models.Model): project = models.ManyToManyField(Project, verbose_name='Projects') name = models.CharField(max_length=100, verbose_name='Name') document = models.FileField(upload_to=document_path, verbose_name="File") doc_type = models.CharField(max_length=30, choices=DOCUMENT_TYPE, verbose_name='Type', null=False) In the view.py I use the following code: .. form = DocumentUploadForm(postdata, request.FILES) if form.is_valid(): newdoc = form.save(commit=False) newdoc.document = request.FILES['document'] newdoc.name = newdoc.document.name newdoc.save() newdoc.project.add(proj) when I try to save the instance (newdoc) I receive the following error: *** ValueError: "<Document: Document object>" needs to have a value for field "document" before this many-to-many relationship can be used. although the newdoc.document field has been instantiated correctly. Could anyone explain where I am going wrong here? Thanks, Antonello -

Silence exception in django template tag
I am writing a very simple template tag, which returns the verbose name of a application: @register.simple_tag def get_verbose_name(app_name): return apps.get_app_config(app_name).verbose_name According to the documentation I should return default values and not throw exceptions if possible. Should I handle the exception and return None or throw it if the question doesn't exist? -

blank=True not working on CloudinaryField()
I am sure this is something simple that I am missing. But I am setting up and image sharing site and I am using cloudinary to directly upload images to the cloud. I have the CloudinaryField field in my models.py like this image = CloudinaryField('image', blank=True, null=True) However when I try to fill out the image field by choosing an image to upload, it does not update the image field and when I submit the form it says no image detected and will not let me create the new image post.

Retrieving one to one related model
I have a profile model that I related to the user model via a onetoonefield. Now I want to pass the profile on to a form so I can edit the profile. I know I can obtain the profile via current_user = request.user get_object_or_404(UserProfile, user=current_user) or current_user = request.user UserProfile.objects.filter(user=current_user) However I figured, since I have the model defined as: class UserProfile(models.Model): user = models.OneToOneField(User, primary_key=True, related_name='user_profile') some_data = models.CharField(max_length=255) I could just do something like myprofile = current_user.user_profile but that doesn't seem to work. Is it possible to do it in someway like that via the related name? -

How to conditionally exclude django admin list display items
I have a quote model in my Django admin, that I set up an admin class for with a list display of some of its fields. One of these fields is a 'partner id'. I have multiple different settings files that extend from a base settings file for whatever environment I'm in. In these settings files, theres a SHOW_PARTNER_ID variable. I want to be able to remove partner_id from the list display if SHOW_PARTNER_ID is set to false, and vice versa. I have a method that returns an empty string for each row of the quote table that doesn't have a partner id, but I would rather just remove the column completely. class QuoteAdmin(admin.ModelAdmin): list_display = ('date', 'device_model', 'first_name', 'last_name', 'customer_address', 'customer_link', 'customer_history', 'site_name', 'status', 'partner_id') def partner_id(self, obj): from django.conf import settings try: if settings.SHOW_PARTNER: if obj.partner: return u'<a href="/admin/quote/partner/{}/">{}</a>'.format(obj.partner.id, obj.partner.id) else: return '' else: return '' except Exception as e: logging.error(e) return '' -

Integrating django with mean stack
I'm working on a project that requires us to implement an email client using web sockets. The problem is, the protocol is written in django and the front end is built in Angular 2 with a node api for user authentication. As we cannot use a library for the protocol in node and lack of skill and time to redo the front end in django we don't have much choice but to integrate both. The question is how to achieve this? I have tried to google it and came up with solutions that involve using socket.io and redis. The solutions I found was based on a model where django is used to build the application and node is a middle-ware service. I am looking for guidance from experienced professionals who might have came across a similar problem. From what little I know the only other option is to integrate the front end ( Angular 2 ) with django and remove the node api. I'm open to different approaches to this problem and/or suggestions on which technologies to use (socket.io or redis or any other). Thanks in advance. -

Performing a Javascript function on a django form before adding to database
I have created a template in Django that makes a form based off a model. When the form is submitted currently the data that was previously in the password field of the form is placed into the database rather than the changed value that is included in the "id_Password" field once the onclick action is performed. What is want is the JavaScript to perform it's function, then the form is submitted with the data that is in the field once the function has been performed.

Django regular class vs model class
I try to manage a small video sites for personal purposes. I have created a class named Video and have a lot of attributes to set inside this class. But there's also a lot of them I don't want to save in my project database. The solution I found for now is to create a volatile "working" class and a model class aside. Selected attributes that are worth to be saved in the database are declared in the model class and the other ones (+ the ones to be saved) are also present in the working class. A kind of "hash id" make the link between the 2 class. For example when I instanciate an object from the working class I will need to retrieve the name of the video it represents in the database and then check for the model object stored in the DB that have the same hash id. I have the feelling this is not the best way to proceed. What would be the straight way to do this kind of thing? Thanks, -
How to test a Django class-based view receives correct arguments?
I can't work out how to test that a Django class-based view receives the expected kwargs from a URL pattern. If I have my urls.py: from django.conf.urls import url from myapp import views urlpatterns = [ # ... url( regex=r"^people/(?P<pk>\d+)/$", view=views.PersonDetailView.as_view(), name='person_detail' ), ] And my views.py: from django.views.generic import DetailView from myapp.models import Person class PersonDetailView(DetailView): model = Person I can test that a request to the URL calls the correct view like this: from django.test import TestCase from django.urls import resolve from myapp import views from myapp.factories import PersonFactory class UrlsTestCase(TestCase): def test_person_detail_view(self): PersonFactory(pk=3) self.assertEqual(resolve('/people/3/').func.__name__, views.PersonDetailView.__name__) But I'd also like to test that a request to /people/3/ results in {'pk': '3'} being passed to PersonDetailView, and I can't work out where in a class-based view receives the kwargs in order to test it (by patching the receiving method, I guess). -
