Using Django-CKeditor and django_comments
couldn't use django-ckeditor with django_comments. I had used with my own apps but there is a weird error on django_comments app. I can see and use the editor but on the first time it shows an error 'This field is required'. and when I try post same comment again with submit button, I can post it but can't use editor again without page refresh cause of CKeditor locks. I use django_comments + fluent_comments + threaddedcomments it all comes from django_comments. so I should able to use it CKeditor. but I get all the time form error. I tried to debug it on fluent_comments/views.py since I use fluent_comments. request.POST.copy() ==> doesn't catch the comment on first time and app shows the error. second time catches and post it but as I said cant use CKEditor again. my django_comments form: class CommentDetailsForm(CommentSecurityForm): """ Handles the specific details of the comment (name, comment, etc.). """ name = forms.CharField(label=pgettext_lazy("Person name", "Name"), max_length=50) email = forms.EmailField(label=_("Email address")) url = forms.URLField(label=_("URL"), required=False) # Translators: 'Comment' is a noun here. comment = forms.CharField(label=_('Comment'), widget=CKEditorWidget(), max_length=COMMENT_MAX_LENGTH) I addded to my fluent_comments form.html: <script type="text/javascript" src="{% static "ckeditor/ckeditor-init.js" %}"></script> <script type="text'/javascript" src="{% static "ckeditor/ckeditor/ckeditor.js" %}"></script> -
I need to save only z values for 3D PointField in Geodjango
I have a location database for some objects using PointField with 3 dimensions. But it turns out some users only have the z coordinate (elevation) for the objects and not x and y. PointField doesn't let me define a point with only z coordinate. I really don't want to break up the PointField into two fields as it is very convenient for me this way. It would be great if there is a work-around that I could use. In []: Point(x=1,y=2,z=3).z Out[]: 3.0 In []: Point(z=3).z Out[]: -
Django Rest Framework: Test Case is not returning correct queryset
I have created an API, using DRF, for products in an inventory that can be accessed by the following endpoint url(r'products/$', views.InventoryList.as_view(), name='product-list').

Integration of Machine Learning with a web application
I'm pretty new to web development, I have experience in machine learning (TensorFlow) and I am looking to integrate a TensorFlow model with a web application. I have experience in Python and a bit of Java, but I would prefer if the app's back end could be written in python, using Django. So, my question; How would a go about integrating a pretrained TensorFlow model with a web app so that it can take data input from users add this to a database and then use the TensorFlow model to make predictions on that data, store those predictions, and return the predictions to the user in one form or another? I want to host all of the computing and data storage on Google Cloud Platform. My other questions: Where do I do the programming for the data processing of the web app? I understand that with Django you have several functions/programs that handle different parts of the web app: the URL, the Template, the View, and the Model. From what I understand the Model is the part that interacts, reads writes, and processes the data in the database. So, could I write the TensorFlow model in the Model? If not … -

Bulk create fails with 1 milion rows
For learning purposes I've created csv files with 10 000 rows and 2nd file with 1 million rows, 4 columns each. The idea is to add the data to the table most efficient. ( I am using SQL Database) First approach - @transaction.atomic @transaction.atomic def insert(request): data_reader = csv.reader(open(csv_filepathname), delimiter=',', quotechar='"') for row in data_reader: nela = Nela() # my model name nela.name = row[0] nela.last = row[1] nela.almost = row[2] nela.number = row[3] nela.save() insert(request) 1) For 10 000 rows it takes 2.1006858348846436 to insert data 2) For 1 million rows it was something around ~220.xx secs My 2nd approach is usage of bulk_create() def insert(request): data_reader = csv.reader(open(csv_filepathname), delimiter=',', quotechar='"') header = next(data_reader) Nela.objects.bulk_create([Nela(name=row[0], last=row[1], almost=row[2], number=row[3]) for row in data_reader]) insert(request) 1) for 10 000 rows it takes 0.4592757225036621 which is cool and over 4 times faster then with @transaction.atomic 2) However, for 1 million rows it fails and it outruns the limit of the SQL base. Does anyone have any idea why such bug appears ? I've been reading django docs bulk_create but besides annotation about batch_size for SQL lite I can't find anything useful. -
Django ModelForm dynamic runTIme field
How would I dynamically add fields on a ModelForm that are not defined on the model at runTime on Django 1.9.7?

For example: class ExampleForm(forms.ModelForm): class Meta: model = Example fields = '__all__' MY_CHOICES = ( ('A', 'Choice A'), ('B', 'Choice B'), ) def __init__(self, *args, **kwargs): super(ExampleForm, self).__init__(*args, **kwargs) self.stuff = forms.ChoiceField(choices=self.MY_CHOICES) # self.fields['stuff'] = forms.ChoiceField(choices=self.MY_CHOICES) Also does not work Returns an error of Unknown field(s) (stuff) specified for Example.

Module not found error when uploading django app to heroku (works locally)
I'm trying to upload my updated django app to heroku - it works in my local system, but when I push my changes, it tells me it can't find a particular module (phonenumber_field).

I have ran pip freeze > requirements.txt, and the module in question is django-phonenumber-field==2.0.0. I have no idea where I'm going wrong, and wondering if someone could shed some light for me.
