Show All Data Using python manage.py shell (Django)
I have tried to migrate my database but am still having issues. I wanted to try and look at all my sites databases via Command Prompt. I want to try and see which columns do or don't exist in models. I did python manage.py shell but then could not work out the queries that would allow me to see all the information in both my sites databases. (project2_env) C:\Users\HP\django_project3>python manage.py shell (InteractiveConsole) >>> from blog.models import Post >>> from django.contrib.auth.models import User >>> User.objects.all() <QuerySet [<User: RossSymonds>, <User: RossTheExplorer>, <User: RossSymondsFacebook>, <User: testuser>]> >>> objects.all() -
Django guardian migration NodeNotFoundError after MIGRATION_MODULES defined for auth
I used django guardian in my project. For a reason, I added a new field to django group model with this code: if not hasattr(Group, 'project'): project = models.ForeignKey(Project, on_delete=models.CASCADE, null=True, related_name='groups') project.contribute_to_class(Group, 'project') So far, everything is ok. But I realized after makemigration command, django adds migration file to outside of my project directory. I want to make this file persistent. I found a solution with defining MIGRATION_MODULES in my settings.py: MIGRATION_MODULES = { 'auth': 'preferences.migrations' # preferences is an app of mine } But this time, django guardian module gives error after makemigration command. The errors are below: Traceback (most recent call last): File "./manage.py", line 16, in execute_from_command_line(sys.argv) File "/usr/local/lib/python3.6/site-packages/django/core/management/init.py", line 381, in execute_from_command_line utility.execute() File "/usr/local/lib/python3.6/site-packages/django/core/management/init.py", line 375, in execute self.fetch_command(subcommand).run_from_argv(self.argv) File "/usr/local/lib/python3.6/site-packages/django/core/management/base.py", line 323, in run_from_argv self.execute(*args, **cmd_options) File "/usr/local/lib/python3.6/site-packages/django/core/management/base.py", line 364, in execute output = self.handle(*args, **options) File "/usr/local/lib/python3.6/site-packages/django_cassandra_engine/management/commands/makemigrations.py", line 22, in handle super(Command, self).handle(*args, **options) File "/usr/local/lib/python3.6/site-packages/django/core/management/base.py", line 83, in wrapped res = handle_func(*args, **kwargs) File "/usr/local/lib/python3.6/site-packages/django/core/management/commands/makemigrations.py", line 87, in handle loader = MigrationLoader(None, ignore_no_migrations=True) File "/usr/local/lib/python3.6/site-packages/django/db/migrations/loader.py", line 49, in init self.build_graph() File "/usr/local/lib/python3.6/site-packages/django/db/migrations/loader.py", line 274, in build_graph raise exc File "/usr/local/lib/python3.6/site-packages/django/db/migrations/loader.py", line 248, in build_graph self.graph.validate_consistency() File "/usr/local/lib/python3.6/site-packages/django/db/migrations/graph.py", line 195, in validate_consistency … -
URL path is added twice when using proxy
Background: I was having a lot of issues with my internet connection so I had to buy an unlimited set of mobile data to be able to work. Unfortunately the internet provider do not allow me to share internet with other devices if the package you bought was an unlimited one. The only way to do it was using a proxy in my Android device to share internet, so with that, I am allowed to use it as hotspot and use internet in my laptop. Issue: I was trying to reach to a server api, and I could from my mobile phone (Android app I am building), but from Postman (in my laptop), I've been getting 404 errors. It is really weird since I can access to absolutely any other webpage/api but not this one specifically. That makes me think it could be something server misconfiguration related, but I am just an Android developer, so I have not idea of what could happen on the backend side. I noticed (as you can see in the image attached: https://imgur.com/a/jtHBA2I) that somehow the URL path is being added twice, the URL should be http://its-jitzone-dev.cloudapp.pe/, but instead, is being modified to http://its-jitzone-dev.cloudapp.pe/http:/its-jitzone-dev.cloudapp.pe.

Dropdown list with 'other' option which displays a text field
I'm trying to write a Django application with a form which includes a field 'how did you hear about us?' which will give a dropdown list (tv commercial, search engine, etc) including an 'other' option.

How to set a Foreign Key based on multiple column with django-import-export?
There's a model defining which combination of department/position needs what types of training. Another model shows employees with all related information. All the data comes from xlsx file via django-import-export. The problem is that I can't figure out how to set a foreign key in employees model based on the unique combination of department and position rows, so each employee gets the training field value accordingly. I've tried this solution but it didn't work (or maybe I did something wrong): https://github.com/django-import-export/django-import-export/issues/375 I'm new to programming and this is my first project. Hope some of you can help. Here is my model defining training for each combination of department/position: class TrainingMatrix(models.Model): department = models.ForeignKey(Department, on_delete=models.CASCADE,blank=False, null=True) position = models.ForeignKey(Position, on_delete=models.CASCADE,blank=False, null=True) training = models.ManyToManyField(Training) Here is the Employee model: class Employee(models.Model): badge = models.CharField(max_length=15, primary_key=True, unique=True) name = models.CharField(max_length=200) department = models.ForeignKey(TrainingMatrix, on_delete=models.CASCADE, null=True, blank=True,related_name='department_name') position = models.ForeignKey(TrainingMatrix, on_delete=models.CASCADE, null=True, blank=True,related_name='position_title') training = models.ForeignKey(TrainingMatrix, on_delete=models.CASCADE, null=True) And the xlsx file's column titles I import: badge, name, position, department -
About modifucation of Whoosh score algorithm
I have 2 questions about whoosh, hope someone can help me. (1) How can I get the number of unique items in given documents, it seem that the funtion “doc_field_length” could only support the number of total tokens in given documents. (2) How can I get the number of a query , for example when a query is " banana apple animal" , the number should be 3. Since I would develop a new scoring method instead of the original one "BM25" My whoosh version 2.7.4, python 3.5.6 Thank you very much -
How to link to other user's profile in django?
What I have been trying is to click the post's author(user that created the post) I want it to redirect me to that user's profile,for example in instagram when you click the user that is on top of the post it redirects you to their profile. Everytime I do that instead of seeing the post's author profile I see the loged in user profile. I think there is something wrong in the views.py file or in the base.html. views.py def profile(request, pk=None): if pk: user = get_object_or_404(User, pk=pk) else: user = request.user args = {'user': user} return render(request, 'profile.html', args) def home(request): created_posts = Create.objects.all().order_by("-added_date") return render(request, 'base.html', {"created_posts": created_posts}) def create(request): if request.method == 'POST': created_date = timezone.now() header1 = request.POST['header'] content1 = request.POST['content'] user = request.user created_obj = Create.objects.create(added_date=created_date, title=header1, content=content1, user=user) created_obj.save() print('create created') return redirect('home') else: print('create not created') return render(request, 'create.html') models.py class Create(models.Model): added_date = models.DateTimeField() title = models.CharField(max_length=200) content = models.CharField(max_length=200) user = models.ForeignKey(User, related_name='user', on_delete=models.CASCADE, default=1) class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) image = models.ImageField(default='default.jpg', upload_to='profile_pics') def __str__(self): return f'{self.user.username} Profile' urls.py urlpatterns = [ path('', views.home, name='home'), path('profile', views.profile, name='profile'), path('profile/<int:pk>/', views.profile, name='profile_pk'), path('create', views.create, name='create'), ] profile.html (shows user's profile) … -
accessing product sub categories like ebay in django form
i am trying to replicate the category structure sites like Ebay use when posting a product. For example, if you want to post an Iphone for sale, you go to post an ad, choose a category from the drop down menu on the form('electronics & computers'), then choose a subcategory of "phones", then the last sub category of "iphone". To create this structure i am using django-categories. Creating a product in the admin page works file, the admin form allows me to choose from a drop down menu of every category, however i can't seem to replicate that same process on my own form, to give users the ability to choose from the many categories. If your not aware if django-categories it is a Modified Preorder Tree Traversal.

Do I need to setup Whitenoise if Deploying with django-heroku?
The Heroku documentation says: The django-heroku package automatically configures your Django application to work on Heroku. It is compatible with Django 2.0 applications. It provides many niceties, including the reading of DATABASE_URL, logging configuration, a Heroku CI–compatible TestRunner, and automatically configures ‘staticfiles’ to “just work”. However, I saw other sources where they recommend setting up whitenoise for handling static files. Do I need whitenois if I setup django-heroku? Thanks. -

Why is Django a 'less secure' app according to Google?
Why does Google consider a request from my Django app to send an email via SMTP (smtp.gmail.com) to be insecure? Reading their security standards is not very helpful: How more secure apps help protect your account When a third-party app meets our security standards, you can: See what level of account access you’re giving the app before you connect your Google Account Let the app access only a relevant part of your Google Account, like your email or calendar Connect your Google Account to the app without exposing your password Disconnect your Google Account from the app at any time This is a very common issue when emailing from Django. There are tutorials and stackoverflow question/answers (second answer) that 'solve' this by changing settings in your google account to allow less secure apps. I had this working and was OK with it until I read this from Control Access to Less Secure Sites: Because Google is beginning to shut off Google Account access to less secure apps, the enforcement option is no longer available. We recommend turning off less secure apps access now. You should start using alternatives to less secure apps. As Google gradually moves away from allowing less … -

Django, Ajax and jQuery - posting form without reloading page and printing "succes" message for user

It have a lot of problems right now but I will fight with them later. Right now I wanted to add this +1 score without refreshing page (like most modern websites).

Here is my code with Broken URL urlpatterns = [ # ex: /restaurants/ path('', views.index, name='index'), # ex: /restaurants/15 path('<int:restaurant_id>/', views.details, name='details'), path('/edit/review/<int:userreview_id>', views.EditReview.as_view(), name='edit-review'), ] Details view def details(request, restaurant_id): # calling restaurant ID and displaying it's data restaurant = get_object_or_404(Restaurant, pk=restaurant_id) # calling a review and displaying it's data user_review_list = UserReview.objects.filter(pk=restaurant_id) user_reviews = [] for user_review in user_review_list: if user_review.posted_by == request.user: user_reviews.append({"user_review_grade": user_review.user_review_grade, "user_review_comment": user_review.user_review_comment, "posted_by": user_review.posted_by, "edit": user_review.get_edit_url}) else: user_reviews.append({"user_review_grade": user_review.user_review_grade, "user_review_comment": user_review.user_review_comment, "posted_by": user_review.posted_by}) return render(request, 'restaurants/details.html', {'restaurant': restaurant, 'user_review_list': user_reviews,}) index template {% extends "base_generic.html" %} {% block content %} <h1>Restauracje Poznan</h1> <p> Search by name or city <form action="{% url 'restaurants:search_results' %}" method="get" class="form-inline"> <div class="form-group mx-sm-3 mb-2"> <input name="q" type="text" placeholder="Search..."> </div> <div> <input type="submit" class="btn btn-primary mb-2" value="Search"> </div> </form> </p> <h2>Restaurants and other gastronomy places:</h2> {% if restaurants_list %} <ul class="list-group"> {% for restaurant in … -
Real time updates in a Django template
I have a django webapp that displays stock data. How it works: I make requests to a stock data API and get data every 15 mins when the US stock market is open. This is a background periodic task using Celery. I have a database where I update this data as soon as I get it from the API. Then I send the updated data from the database to a view, where I can visualize it in a HTML table. Using jQuery I refresh the table every 5mins to give it a feel of "real time", although it is not. My goal is to get the HTML table updated (or item by item) as soon as the database gets updated too, making it 100% real time. The website will have registered users (up to 2500-5000 users) that will be visualizing this data at the same time. I have googled around and didn't find much info. There's django channels (websockets), but all the tutorials I've seen are focused on building real time chats. I'm not sure how efficient websockets are since I have zero experience with them. The website is hosted on Heroku Hobby for what its worth. My goal is …
