SeleniumBase Django Integration
I recently stumbled across a way to make selenium faster using SeleniumBase. I am working on a website that has to parse a google shopping page. It uses selenium to wake the page up because there is javascript on the page and it uses BeautifulSoup to parse the page contents... and it's slow. I have been trying for a few days now to integrate Django and SeleniumBase with no luck. The Django views combined with the class structure of selenium base is stretching my knowledge of raw python. I have a function at the bottom of my code that parses the page content that includes SeleniumBase and BeautifulSoup and a call of the function and forloop at the top to loop through the contents. I have gotten several error messages and I still think I am far away from the solution so I don't feel there is a need to post them here because none seemed too significant. Any help is greatly appreciated. P.S. I am slightly new to django and python and really new to Selenium and SeleniumBase def home(request): form = SearchForm(request.POST or None) if form.is_valid(): form.save() if request.POST: for google_post in google_initiate(request, self): #Do some stuff #Make … -
How to retrieve the method of a Django model by specifying parameters in the URL with REST framework?
I have a model Account with a ForeignKey user and a method total_value() that returns a float64. I would like to GET the float value by entering the account and user primary keys as parameters in the URL. To do that I catch parameters with request.query_params and select the desired Account object but the framework throws an error. What amI missing ? https://mysite/api/widget/total/?account=1&owner=1 'Account' object is not iterable Please find my code below. models.py class Account(TimestampedModel): name = models.CharField(max_length=20, null=True, blank=True) user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) def total_value(self): return do_stuff(self) serializer.py class TotalAssetsValueSerializer(serializers.ModelSerializer): class Meta: model = Account fields = ('total_value',) view.py class TotalAssetsValueView(viewsets.ModelViewSet): serializer_class = TotalAssetsValueSerializer http_method_names = ['get'] def get_queryset(self): user = self.request.query_params.get('user') account = self.request.query_params.get('account') return Account.objects.get(pk=account, user=user) I'm sure there an account with pk=1 and user=1, so maybe my mistake is that I return an object not a queryset. Unfortunnatly when I filter instead of get it return []. -

Django pass variable to Python script
I have a Django app, with 2 pages: index.html and device_list.html Index page: <div class="search"> <form action="" method="POST"> {% csrf_token %} {{ form.as_p }} <input type="text" class="input" name="UserInput"> </form> </div> <div class="btn"> <button class="btns" onclick="location.href='{% url 'script' %}'">Generate</button> </div> </div> here is device_list.html page: {% extends "base.html" %} {% block content %} {{output}} {% endblock content %} Views.py: def index(request): return render(request, 'index.html') def device_list(request): if request.method == 'POST': form = SiteCodeForm(request.POST) if form.is_valid(): command = ["python","run.py","VARIABLE" ] process = Popen(command, stdout=PIPE, stderr=STDOUT) output = process.stdout.read() print(output) ----- IM STUCK HERE ----- So I don't know how to proceed, and pass the variable from index page to the python script that I have in views. It actually runs the script, and I can see the result in the terminal, but the output won't show up in the device_list.html - it's empty. -
Django : NoReverseMatch
Im having issues with indexing inside reference point in url. I have quite complicated nested object of two raw quries and string inside tuple inside list. Point is that referencing sometimes works and sometimes does not and I don't really get why. This piece of html works really well. <td><a href="{% url 'company_info' pair.0.0.0.ticker %}">{{pair.0.0.0.ticker}}</a></td> But this one fails <td><a href="{% url 'company_info' pair.1.0.0.ticker %}">{{pair.1.0.0.ticker}}</a></td> What's more django properly renders this : <td>{{pair.1.0.0.ticker}}</td> But has problem with this one : <a href="{% url 'company_info' pair.1.0.0.ticker %}"> Which really indexes the same object. So in one place its ok and in another it fails. What might be causing that? Sorry if its a little bit messy explanation but html its not really my thing and I might lack some vocabulary. Best! -
Initialize django ModelForm user field with current logged user

Bonus question: Why pub_date field, which is a DateTimeField, is displayed as text type? I can't change it. -

Django - button redirecting to {% url 'index' %}

Why django runserver command starts 2 processes? What are they for? And how to distinguish between each in the code?
While building some standalone Django app, which will be running tasks in the background as a separate daemon Thread, I ran into a problem because it seemed as if there are two MainThreads when starting the Django server, each Thread has a different id. After digging more into the problem, it turned out that it's because it's actually two processes. Experiement: Run django-admin startproject example && cd example to start a new project.
