Getting and setting data in sqlite in django
So, I'm trying to update some information in sqlite db in django. What I wanna do is the following: 1. I get existing data from the db 2. Based on the data, I do some calculations on the given data to make new data. 3. After getting the new data, I put them in the sqlite db. I wanna do the process above manually or automatically. I'm currently using django framework to make some web application. In my website, there's a bunch of stores having customer reviews, and I wanna make popularity points of each store based on calculations of the reviews. How can I update data of a column based on data of another column? -
How can I launch a new terminal to track my shell script triggered from Django?
I'm working on a Django 2.0.2 project built in python 3.6.3 which necessitates forking off a shell script as a background child process. This is currently how I'm currently triggering it: import subprocess subprocess.Popen(./master.sh) Unfortunately, this doesn't echo to the same terminal as the Dango server like other processes on the site. The pipeline outputs to a log.txt file after completing, but as some jobs will take hours to complete, I'd like a way to follow the job as it happens by spawning a new terminal. I have tried using gnome-terminal commands, but so far I've had no successful readout. -

How do I filter access to certain views based on time?
I am trying to create a system whereby users can only access a certain page at a time which they have booked. Users who have not booked access to this time will not be able to access the page.

I am trying everything I can to do it see my files below. models.py class Booking(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE, null=True) daterequired = models.DateTimeField(default=timezone.now) students = models.CharField(max_length=200) length = models.CharField(max_length=40, blank=True) def __str__(self): return str(self.user) forms.py class BookingForm(forms.ModelForm): class Meta: model = Booking exclude = ['user', ] widgets = { 'students': forms.TextInput(attrs={'placeholder': 'Number of Students'}), 'length': forms.TextInput( attrs={'placeholder': 'Time needed in hours'}), } views.py @login_required def choose(request): pod = Pod.objects.all() booking = Booking.objects.filter(user=request.user) bookingtime = booking.daterequired.strftime("%Y-%m-%d %H:%M:%S") currenttime = datetime.now().strftime("%Y-%m-%d %H:%M:%S") timedifference = currenttime - bookingtime if timedifference <= booking.length: return render(request, 'choose.html', {'pod': pod, 'booking': booking}) else: return HttpResponse("<p>NO ACCESS</p>") I am not sure how far off I am at the moment but would appreciate any help in the right direction. Thanks guys! -
Django not passing data to views on POST request
I've created a dropdown menu that is supposed to pass data to a view that'll help filter a queryset. However, it doesn't seem like the data is actually being passed to the view. Below is the relevant code I've written. template.html <!-- Query based content for dropdown menu --> <form method="POST" action="{% url 'property-selected' %}" id="property-select"> {% csrf_token %} <select class="dropdown-content" onchange="this.form.submit()" name="property-select"> {% if current_user_meters %} <option disabled selected> -- select an option -- </option> {% for meter in current_user_meters %} <option class="dropdown-menu-option" value="{{meter.id}}">{{meter.name}}</option> {% endfor %} {% else %} <option>You don't have any meters</option> {% endif %} </select> </form> views.py def property_selected(request): if request.method == 'POST': selection = request.POST.get('property-select') current_user_groups = Group.objects.filter(id__in=request.user.groups.all()) current_user_properties = Property.objects.filter(groups__in=current_user_groups) current_user_meters = Meter.objects.filter(meter_id__in=current_user_properties) selected_meters = Meter.objects.filter(name=selection) selected_meter_data = MeterData.objects.filter(name=selection).order_by('date') return render(request, 'properties/property-selected.html', { 'current_user_meters': current_user_meters, 'selection': selection, 'selectected_meters': selected_meters, 'selected_meter_data': selected_meter_data, }) for the querysets in the views file, the "selection" variable doesn't seem to be getting anything, which is where I want the data from the POST request to go. I want the data from the POST request to go there so my "selected_meters" and "selected_meter_data" queries will work as intended. Thanks! -
EditForm won't save the image from my ImageField

Django POST shows in form, but doesn't come through to the next view
I have a simple form such as: <form action = "{% url 'endresult' %}" form method = "POST"> {% csrf_token %} <div class="well"> <h4 style="margin-top: 0"><strong> Student Details </strong></h4> <div class="row"> <div class="form-group col-md-4"> <label/> Student ID <input class="form-control" type="text" name = "studentpost" placeholder= "{{student.studentid}}" readonly> </div> </form> </div> The student ID does show up in my form, but when I try to get the results from endresult it shows up as a blank, if i try to call the studentid i get none.

What is better for an embedded device - Node.js or Django?
Background: I'm currently developing a project on Raspberry Pi - for now I want to gather data from a sensor and display it on a web page with some neat graphs and stuff like that but I plan to expand it sooner or later. I'm facing a dilemma right now: which framework should I use? I learned about Node.js from this book and I really like the concept - also the authors are giving quite a few reasons why it's good for embedded devices. On the other hand, I learned about the existence of Django and since I'm working with python on a daily basis I thought using it would be a better idea. I'm torn apart now - I'd like to use technology that would be most suitable in embedded world (and which would educate me the most) and yet I'm kinda afraid to jump into deep waters of a language I don't really know (JavaScript). If somebody with more experience with web technology and embedded devices could help me out, that would be most helpful! In short: What would be the best option for an embedded device (and for me): Node.js or Django? -

Django Dynamic Form Filter
I'm creating a web based ERP-like system in Django 2.0. In a page, I have a form with all the Work Orders or so entries (stored in DB). I would like to have in the first line of the form (below the headers) a input field for each column where I type and it dynamically/instantly filter the form rows. Example: COD | DESCRIPTION | DATE | ETC. search field | search field | search field | search field So when I type any character in any column, instantly the form is updated showing the filter results. Which technique I should use for this? Is Ajax the tool for this job? -
Creating an REST API Django
First thing that I would like to say is that I have no previous experience with python and any framework python related. However, I have programming experience. So, I want to create an REST API using pythona with frameworks djnago and djangorestframework. I have managed to create the database (using postgresql) and also managed to to create the initial migration. However, I believe that that was the easiest part and I have some questions about the thing that I'm about to implement: First I want to create an authentication system. I saw that djangorestframework it's able to manage authentication by itself but I was not able to make it run. Can you please guid me to some good tutorials/provide code samples and briefly explain? After initial migration I saw that django created some tables for authentication and session management by itself (auth_user, auth_user_groups, etc). Is there any way to use my own model for user? Also, i do believe that I wont need all the features that django offerrs (e.g auth_user_groups). Its there any way to remove those unwanted functionalities? I was able to create an API endpoint (by following a tutorial) that returns some data (based on a model, … -

I change that to 2.0 and django to 2.0, rerun the import and I get this error: Traceback (most recent call last): File "./manage.py", line 12, in <module> execute_from_command_line(sys.argv) File "/Users/johnbriggs/.virtualenvs/wagtail/lib/python3.6/site-packages/django/core/management/__init__.py", line 371, in execute_from_command_line utility.execute() File "/Users/johnbriggs/.virtualenvs/wagtail/lib/python3.6/site-packages/django/core/management/__init__.py", line 347, in execute django.setup() File "/Users/johnbriggs/.virtualenvs/wagtail/lib/python3.6/site-packages/django/__init__.py", line 24, in setup apps.populate(settings.INSTALLED_APPS) File "/Users/johnbriggs/.virtualenvs/wagtail/lib/python3.6/site-packages/django/apps/registry.py", line 89, in populate app_config = AppConfig.create(entry) File "/Users/johnbriggs/.virtualenvs/wagtail/lib/python3.6/site-packages/django/apps/config.py", line 123, in create import_module(entry) File "/Users/johnbriggs/.virtualenvs/wagtail/lib/python3.6/importlib/__init__.py", line 126, in import_module return _bootstrap._gcd_import(name[level:], package, level) File "<frozen importlib._bootstrap>", line 994, in _gcd_import File "<frozen importlib._bootstrap>", line 971, in _find_and_load File "<frozen importlib._bootstrap>", line 953, in _find_and_load_unlocked ModuleNotFoundError: No module named 'wagtail.wagtailforms' Here is my updated requirements.txt file: Django>=2.03 wagtail>=2.0 I can run these fine, but everything bugs at at the migrate process. -

How to display python dictionary in a Django template in bullet list format?
How do I alter the following Django template code: <ul> {% for key, value in real_prices.items %} #real_prices is a dictionary <li>Price: {{ key }}, link: {{value}}</li> {% endfor %} </ul> To display the dictionary items on a page like this: Price: key, link: value Price: key, link: value Price: key, link: value and so on... The current code only displays the dictionary as a whole. For reference, here's the view: def test(request): prices = [] real_prices = [] links = [] url = 'https://www.airbnb.pl/s/Girona--Hiszpania/homes?refinement_paths%5B%5D=%2Fhomes&query=Girona%2C%20Hiszpania&place_id=ChIJRRrTHsPNuhIRQMqjIeD6AAM&checkin=2018-04-04&checkout=2018-04-22&children=0&infants=0&adults=2&guests=2&allow_override%5B%5D=&price_max=252&room_types%5B%5D=Entire%20home%2Fapt&min_beds=0&s_tag=Ph6ohhjw' response = requests.get(url) soup = bs4.BeautifulSoup(response.text) #prices page_selectors = soup.select('._1bdke5s') print(len(page_selectors)) last_page_selector = page_selectors[len(page_selectors) - 4]##############-15 last_page_selector = last_page_selector.getText() for x in range(0, int(last_page_selector)): response = requests.get(url + '&section_offset=' + str(x)) response_text = response.text soup = bs4.BeautifulSoup(response_text) spans = soup.select('._hylizj6 span') for i in range(0, len(spans)): prices.append(spans[i].getText()) for price in prices: if 'zł' in price: real_prices.append(price) #links a_tags = soup.find_all('a') for tag in a_tags: if '_15ns6vh' in str(tag.get('class')): link = 'https://www.airbnb.pl' + str(tag.get('href')) links.append(link) dictionary = dict(zip(real_prices, links)) -

Create a session in Django Rest Framework
I have a Django Rest Framework API that authenticates through Firebase. On the frontend after the user has logged in with Firebase, a token is sent to the backend that is verified, Firebase returns a user_id after verification and this is used to return the current user. I have written a simple custom authentication class that handles the token verification. The token is set as tokenid header. Here's the code: from rest_framework.authentication import BaseAuthentication from rest_framework import exceptions import firebase_admin from firebase_admin import credentials, auth from .models import User CREDS_PATH = 'PATH_TO_CREDS.json' cred = credentials.Certificate(CREDS_PATH) default_app = firebase_admin.initialize_app(cred) class FirebaseAuthentication(BaseAuthentication): """Authenticate the user and get its info from Firebase. The token is sent in the request as idToken and veryfied with the Firebase admin. """ def authenticate(self, request): """Actual authentication happens here.""" token = request.META.get('HTTP_TOKENID') if token: try: firebase_user = auth.verify_id_token(token) except ValueError: return None if not firebase_user: return None user_id = firebase_user.get('user_id') try: user = User.objects.get(id=user_id) print(user) except User.DoesNotExist: raise exceptions.AuthenticationFailed('No such user') return (user, None) else: # no token provided return None Then I create a View that is connected to /login route and that uses FirebaseAuthentication and SessionAuthentication. The idea is for this endpoint to verify the … -
django username "disappears" when going in another view
Before I start, I'd like to point out that I have already surfed half of the internet in search of a possible solution, but nothing really solved my problem. That said, I'm quite the beginner in Django and Python so this could be a simple problem and maybe I'm just too dumb to figure it out. So, here's the thing. I'm working on a project for college and I have to make a website that emphasises primarily backend. I chose Django as a framework and so far I've been able to have new users register and also log in and out. The problem is maybe not dramatic, but annoying for me at least. To be more clear, After a user logs in, I want to show his name in the top bar alongside the logout button. So, the log in panel is as such: This part is fine, I just hit Log In and it works. Then I get here: As you can see, at first, the username is displayed in the top bar alongside the logout. But if I click on "Whatever" or the username itself, it goes away. This may have something to do with the fact that …
