How can I show my custom user and user in same form and make it work?
I have 2 models: teacher and student. They both extend User class with a OneToOneField and they both have receivers defined for creation and saving. Now, in my forms I can only display the fields from student or teacher only, the other fields that come with user I don't know how to include them. But I want that a student or a teacher won't be able to create account, unless all fields are filled in. Here are my forms and view: class StudentSignUpView(CreateView): model = User form_class = StudentSignUpForm template_name = 'student_signup_form.html' def get_context_data(self, **kwargs): kwargs['user_type'] = 'student' return super().get_context_data(**kwargs) def form_valid(self, form): user = form.save() login(self.request, user) return redirect('index') class TeacherSignUpView(CreateView): model = User form_class = TeacherSignUpForm template_name = 'teacher_signup_form.html' def get_context_data(self, **kwargs): kwargs['user_type'] = 'teacher' return super().get_context_data(**kwargs) def form_valid(self, form): user = form.save() login(self.request, user) return render_to_response('index.html', {'form': form},) class StudentSignUpForm(forms.ModelForm): class Meta: model = Student fields = ('student_ID', 'photo', 'phone') class TeacherSignUpForm(forms.ModelForm): class Meta: model = Teacher fields = ('academic_title', 'photo', 'phone', 'website', 'bio') -
Why won't importlib find my module
I'm trying to programmatically import a module. This works: from dirname.models import modelclass as m But this doesn't: import importlib m = importlib.import_module('models.modelclass', package='dirname') I try running this script from the directory that holds dirname. dirname contains a init.py file. I'm trying to make this work using django. I get an ImportError saying "No module named 'models'" -

django-mssql database error, SQL query error
I am using django-mssql to connect to the database. I am doing a raw sql query to the database but I get this error. django.db.utils.DatabaseError: (-2147352567, 'Exception occurred .', (0, 'Microsoft SQL Server Native Client 11.0', 'Error conver ting data type varchar to bigint.', None, 0, -2147217913), None) Command: SELECT Attribute FROM ML.attribute WHERE CompanyID = '1' AND Att ributeID NOT IN (SELECT AttributeID FROM ML.correlatedattribute WHERE ProductID ='AUTO_LOAN')AND (Useless != 1 OR Useless IS NUL L) The body of function calling the database is like this def query(query_string): cursor = connection.cursor() cursor.execute(query_string) rows = cursor.fetchall() cursor.close() return rows The error seems to be something to do with data type but I have no idea how to solve this. -
What are the most user-friendly methods to create interactive graphics/charts on a webpage?
I'm looking to create a webpage with interactive charts that can be updated on the back-end by a MySQL database. IE. A website that hosts a graph that has points which can be clicked on for additional information. I have a background in Python programming and have started looking over Django documentation but am struggling with following the documentation's tutorial as I progress. Are there other languages, methods or perhaps Django tutorials that anyone can recommend for a project like this? Looking for video material myself hasn't reaped much success. -
Invoke a seperate event when I click on a hyperlink on my Django template page
I have an tag on my Django template for an advert that fulfills two functions: When a user clicks it, data is logged about the click (its location on the page, the text of the link, etc.) It is then redirected to an external link on a different website. The way the page template is loaded is that the tag is dynamically filled with the href attribute pointing towards a view function in my views.py : <a href="url arg1&arg2&redirect_url" target="_blank"> <span dir="ltr">Lawyer Education</span> </a> The problem is that in practice, when a user hovers over my hyperlink, on the bottom left of the browser they see the URL pointing towards the view and its DJango url with arguments is displayed as opposed to the URL they are expecting to be redirected to. Is it possible to have the redirect URL be displayed instead in some way? Or to have the view function be fired as an event while the redirect occurs at the same time? Javascript/jQuery/PHP is not my forte so I am not sure how to proceed if that is the way to go to solve my problem... -
Start Scraping Process in Django App
I recently had a developer work on a project with me for a web application that scrapes news articles and allows assesses them uses NLP. I'm new to Python and have never used Django before, but have managed to get the app up and running on a host. Unfortunately the developer is now unavailable and although the project is almost ready, I'm not exactly sure how to execute the scraping process. It uses the following packages: beautifulsoup4==4.6.0 dj-database-url==0.4.1 Django>=1.9.7 django-allauth==0.32.0 django-filter==1.0.4 django-taggit==0.22.1 djangorestframework==3.6.3 django-taggit-serializer==0.1.5 feedfinder2==0.0.4 feedparser==5.2.1 gunicorn==19.6.0 newspaper3k==0.2.2 nltk==3.2.4 parsedatetime==2.1 psycopg2==2.7.1 virtualenv==15.1.0 whitenoise==2.0.6 oauthlib==2.0.2 requests-oauthlib==0.8.0 django-rest-auth==0.9.1 markdown word2number django-cors-headers Does anyone who knows Django and/or the installed packages know where I might find the scripts if they are there? The repository is available here: https://github.com/davemate23/swendle I have the app and database running locally, so understanding how to start the scraping and NLP/data analysis process would be really helpful.

Where is robots.txt coming from (Nginx + Gunicorn + Django)?
I am running a server with Nginx + Gunicorn + Django. I have configured Django to show a robots.txt file, and this works just fine when I test Django on its own, without Nginx+Gunicorn. However, when I run the whole stack, /robots.txt suddenly gets replaced with a different file that I didn't write. Why is this happening? I never wrote anything to tell Nginx or Gunicorn to do such a thing. Is there a default somewhere that I need to overwrite or deactivate? The folder /etc/nginx/sites-enabled contains only my own sites file, and it doesn't mention /robots explicitly. It just has a location block targeting / which gets routed to Gunicorn+Django, and for every site except robots.txt this works just fine. -
Elastic Beanstalk + S3 and easy-thumbnails for django create timeout
I am using the easy-thumbnails module for django. The django app gets deployed on elastic beanstalk and images hosted on S3. When a user uploads an image he gets redirected to a page which shows the thumbnail, generated with easy-thumbnails. This however gives me a 500 Server error. When I wait a little bit and refresh the page, everythings works fine, which leads me to believe that some kind of timeout occurs on thumbnail generation. Of course once the image is generated everything works fine. I could not find any errors in the logs however, even with THUMBNAIL-DEBUG = True. Any leads to a solution would be greatly appreciated. -

How to make Django validators dynamic?
I am new to Django. I am taking over a Django project developed by someone else. They took the basic form validators from here: https://docs.djangoproject.com/en/2.0/topics/auth/passwords/ So if I open settings/common.py I see: AUTH_PASSWORD_VALIDATORS = [ { 'NAME': 'django.contrib.auth.password_validation.UserAttributeSimilarityValidator', }, { 'NAME': 'django.contrib.auth.password_validation.MinimumLengthValidator', 'OPTIONS': { 'min_length': 9, } }, { 'NAME': 'django.contrib.auth.password_validation.CommonPasswordValidator', }, { 'NAME': 'django.contrib.auth.password_validation.NumericPasswordValidator', }, ] My project manager is telling me that she wants these validators to happen while a person is typing, rather than when the form is submit. So I need to somehow make these validators trigger onBlur as the cursor leaves each field. How is this done in Django? -

User input associates to photo
Working on a blog, where users can create new posts and input a keyword to have a picture associated with that keyword provide a photo for the post. For example: 1) User inputs keyword: 'Pizza' 2) The form page that the user is on either: a) uses that keyword to provide an image associated with it or b) uses that keyword to provide a couple images that the user can then choose from for the image for the post 3) The selected image is then associated with that post Does anyone have suggestions on how to implement this? I'm keen to work on it, but can't even think where to start. Is there a google images plugin that i could use? Or any sample codes? -

I'm seeking guidance to get me going in the right direction. My professor is at a loss. I'm having issues with the POST in my form for the select2 multiple fields. I have a Yes/No flag, that determines which select 2 select option to show.

Django URL keeps being longer

Django 2.0 URL regular expressions
I'm trying set an offset but I want to limit it to a maximum of 99 hours by only allowing either one- or two-digit numbers but I'm not sure of the syntax to use with Django 2.0. I've tried to look for updated documentation but I can't find it, maybe I missed it but I did look before posting here. Here is the code in my views.py file: # Creating a view for showing current datetime + and offset of x amount of hrs def hours_ahead(request, offset): try: offset = int(offset) except ValueError: # Throws an error if the offset contains anything other than an integer raise Http404() dt = datetime.datetime.now() + datetime.timedelta(hours=offset) html = "<html><body>In %s hour(s), it will be %s.</body></html>" % (offset, dt) return HttpResponse(html) Here is the code from my urls.py file, this allows me to pass an integer but I want to limit this to 1- or 2- digit numbers only: path('date_and_time/plus/<int:offset>/', hours_ahead), I've tried path(r'^date_and_time/plus/\d{1,2}/$', hours_ahead), but I get the Page not found (404) error.

Restricting all the views to authenticated users in Django
I'm new to Django and I'm working on a project which has a login page as its index and a signup page. The rest of the pages all must be restricted to logged in users and if an unauthenticated user attempts to reach them, he/she must be redirected to the login page. I see that @login_required decorator would make a single view restricted to logged in users but is there a better way to make all the views restricted and only a few available to unauthenticated users? -
How to access one to many relationship after bulk_create in Django

Django: Using Template Tags with ckeditor

This is my models.py: class Category(models.Model): name = models.CharField(max_length=200, db_index=True) slug = models.SlugField(max_length=200, db_index=True, unique=True) class Meta: ordering = ('name', ) verbose_name = 'category' verbose_name_plural = 'categories' def __str__(self): return self.name def get_absolute_url(self): return reverse('products:product_list_by_category', args=[self.slug]) class Product(models.Model): category = models.ForeignKey(Category, related_name='products') name = models.CharField(max_length=200, db_index=True) slug = models.SlugField(max_length=200, db_index=True) description = models.TextField(blank=True) price = models.DecimalField(max_digits=10, decimal_places=2) stock = models.PositiveIntegerField() available = models.BooleanField(default=True) updated_at = models.DateTimeField(auto_now=True) class Meta: ordering = ('name', ) index_together = (('id', 'slug'), ) def __str__(self): return self.name def get_absolute_url(self): return reverse('products:product_detail', args=[self.id, self.slug]) class ProductImage(models.Model): property = models.ForeignKey('Product', related_name='images', on_delete=models.CASCADE) image = models.ImageField(upload_to='products') And this is my views.py: def product_list(request, category_slug=None): category = None categories = Category.objects.all() products = Product.objects.filter(available=True) product_img = Product.images.all() if category_slug: category = get_object_or_404(Category, slug=category_slug) products = products.filter(category=category) return render(request, 'products/list.html', {'category': category, 'categories': categories, 'products': products, 'product_img': product_img}) I've seen similar post here on stack overflow, and have tried to do the same thing, but I still get the following error: AttributeError: 'ReverseManyToOneDescriptor' object …
