ModuleNotFoundError: No module named 'google' in GCP app
I have a Django app that I am trying to deploy to GCP. The app works perfectly fine when I run it locally, and it deploys with no issue to GCP (via gcloud app deploy). When I open the webpage, I get this error "502 Bad Gateway 502 nginx" due to "ModuleNotFoundError: No module named 'google'". I haven't been able to find how to properly import google into my GCP app. More details below, any help is appreciated.

How to upload a big size folder to GCS using angular 9?
I have to upload a huge size of the folder(approx 150GB ) to GCS. I am using Angular 9 as front-end and Django for the backend. Please tell me the best approach for this. The approach in my mind is: Take a token from the back-end and upload the file one by one(using GCS API). Upload all the files one-by-one in the Django server than upload it to GCS. Zip the folder and upload it to Django and then extract and upload it to GCS(but I have no idea,how to upload a big zip file using angular). Please suggest to me what can I do and how? -

How to use the django-admin-search with search_FieldNameHere ? I am unable to use the same
The django-admin-search plugin version 0.3.5 has beem installed with django 3.0.5 on linux. How exactly to use the search_field query, I fail to understand. I am not great working with OOPS yet. What I tried: def search_mfrom(request, field_value, param_values): """ intercept query filter for description field """ query = Q() #print(request, field_value, param_values, 'llllllllllllll') query = Q(mfrom='sowmiya@abc.com') print(query, 'qqqqqqqqqqqq') return query The print(query, 'qqqqqqqqqqq') never executes. Am I passing in something wrong? The form field is mfrom. Secondly, wish to send in login specific records in queryset which this tool is overriding. How to do that? I am able to override the queryset based on login domain part of the request.user, but since this tool is also overriding the queryset object of the modeladmin, I don't know how to go about. The code snippet for the same: def get_queryset(self, request): domain_list = [] temp = [] qs = super(LogSearchFormAdmin, self).get_queryset(request) if request.user.is_superuser: return qs else: domain_list = Domain.objects.filter( customer__in=Customer.objects.filter( email=request.user.username)).values_list( 'name', flat=True) #print(list(domain_list)) dom_names = list(domain_list) #print(dom_names) qs = MailLogs.objects.none() if dom_names: for d in dom_names: qs = MailLogs.objects.filter( Q(mfrom__icontains=d)|Q(mto__icontains=d)) # qs |= MailLogs.objects.filter(mfrom__icontains=d) # qs |= MailLogs.objects.filter(mto__icontains=d) print(qs.query) #print(qs) return qs -

How to always let heroku run a command on deployment for a django project?
I was working on a django project. The Procfile is the place that heroku always looks on before deployment. Currently it is configured this way and it works all fine. web: python manage.py collectstatic --no-input; gunicorn project_folder.wsgi --log-file - --log-level debug This means it runs collectstatic command every time I make any changes in my project and deploy it on server. Can the same thing apply to run a background task? This background task needs to run automatically after my project is deployed. python manage.py process_tasks is what I type in my command to trigger this background_task in django on my local server. So, would something like this below be invoked the same way as python manage.py collectstatic serves(that is collecting all static files in my static folder)? web: python manage.py collectstatic --no-input; python manage.py process_tasks; gunicorn project_folder.wsgi --log-file - --log-level debug -
Redirect set of included URL patterns in django
For my Django app, I've always had my Dashboard pages prefixed with /site/dashboard/ urlpatterns = [ path('site/dashboard/', include('dashboard.urls')), ] I'd like to simplify the URLs and change it so the pages are just /dashboard/ urlpatterns = [ path('dashboard/', include('dashboard.urls')), ] I'm familiar with doing a RedirectView in URLs to redirect to a different single url/view. How would I do this with an entire set of views, so all the old /site/dashboard/ URLs in dashboard.urls were marked with a 301 redirect to the new URLs? -

Can't store a Selenium web driver object to recover it through Django views
After days of research, I wasn't able to properly store a Selenium web driver object to recover it through different Django views. In fact, My project has only one view, and all I need is to recover the same instance of the web driver object every time that view is called. All my app does is making AJAX post requests to the view and updating the frontend and some data in the web driver window. Having initialized the driver as driver = webdriver.Chrome(executable_path=driverpath, desired_capabilities=caps) , these are all the things that I tried: 1) Storing the object in request.session array. Of course this doesn't work, a web driver object is to complex to be JSON serialized. TypeError: Object of type WebDriver is not JSON serializable 2) Pickle Serialize: Didn't work. A code like pickle.dumps(driver, open( "driver.p", "wb" )) throws this error AttributeError: Can't pickle local object '_createenviron.<locals>.encode' 3) Creating a new driver and assigning to its session_id attribute the previous web driver session_id value. Didn't work. This was the approach: request.session['driver_id'] = driver.session_id #And then on another view call: chrome_options = Options() chrome_options.add_argument("--headless") #to prevent opening a new window new_driver = webdriver.Chrome(options=chrome_options) new_driver.session_id = request.session['driver_id'] 4) Using Ctypes: This is … -
Django custom user model with BaseUserManager set is_active=True not working
I'm working on a project using Python(3.7) & Django(3) in which I have implemented a custom user model and inside the User manager, under create_user method I set user.is_active = True but it's not working on signup.

Django refresh page but dont redirect
On the page /home I created a login button in my navbar and when you click on it it will open a kind of a popup with changing display to block. But my problem is that I cant find out how the user could stay on the page when logging in with wrong data. At the moment it just returns me to the /home page and if I click again on the navbar button the login window opens with the "error" message but I want it to either redirect me to the /home page but the login popup is still opened or just don't redirect me anywhere. So I think I am just looking for a way that this message updates but you stay on the login popup. Here is my part of the views.py: def post(self, request, *args, **kwargs): # form = UserCreationForm(request.POST) # print(form.errors) # <process form cleaned data> username = request.POST.get('username') password = request.POST.get('password') user = authenticate(request, username=username, password=password) if user is not None: print(user, "has successfully logged in") login(request, user) return HttpResponseRedirect('/recipes/all') else: messages.error(request,"Password or username is incorrect") return HttpResponseRedirect('/recipes/all') And here is the part of my HTML file: <div class="login-popup-box" id="login-popup-box"> <div class="user-card-login"> <div class="close-button-box"> … -
