Pagination Error in Django: object of type 'Custom Filter' has no len()
I am having a few issues with Django pagination. I keep getting object of type 'Custom Filter' has no len()` error. I don't know why I keep getting this error. Although I have the premonition that the error may have been triggered due to my use of filter.qs. Anyone with a suggestion on how this can be resolved? views.py def crm(request): #filtering the customer queryset customers_list = ProspectiveCustomer.objects.all() customers = CustomerFilter(request.GET, queryset=customers_list) has_filter = any(field in request.GET for field in set(customers.get_fields())) #pagination paginator = Paginator(customers_list, 10) # Show 10 customers per page. page_number = request.GET.get('page') page_obj = paginator.get_page(page_number) try: customers_list = paginator.page(page_number) except PageNotAnInteger: customers_list = paginator.page(1) except EmptyPage: customers_list = paginator.page(paginator.num_pages) return render(request, 'crm/crm.html', { ...

Using a background image in Django using static and variable
I've seen a lot of these types of questions but none are using a {{ variable_name }} in the html using background. For context, I'm trying to insert a unique photo as a background image for every page. <heading id="background-image" style="background-image: url({% static 'img/pattern.jpg' %});"> This will work for a specific background image, "pattern", but I want it to be dependent on a variable for that specific page. The following code will import the correct image on the page, but it needs to be turned to a background image (so that I may put text in front) <img src="{% static 'img/' %}{{ item.name }}.jpg" alt="item picture"> -

I want to create some kind of gallery.

How to use extends tag in django templates?

How to solve a string to data conversion problem on a Django template
I have a string to data conversion problem on a Django template. I'm trying to take a string (of a date) and calculate the days since that date; so it says something like "1 month, 2 weeks (since all time high date)". The string to date conversion is working fine, the problem is on the Django template. The template currently shows only the last date from the json data request for each item in returned in the for loop. Obviously I need the date for each specific record converted and displayed. I've formatted the string from the json data request into date object. Currently only the last item in the list is being sent as the days_since_ath_formatted variable. Here's the Django view def: coin_list_url = f"https://api.coingecko.com/api/v3/coins/markets?vs_currency=usd&order=market_cap_desc&per_page={per_page_limit}&page=1&sparkline=false" request_coin_list = requests.get(coin_list_url) results_coin_list = request_coin_list.json() crypto_data_geckco = [] #string to date conversion def to_string(time): return time.strftime('%Y %M %d') def from_string(date, formatting): dt = datetime.datetime.strptime(date, formatting) return dt #for loop for currency_gecko in results_coin_list: days_since_ath = currency_gecko['ath_date'] days_since_ath_formatted = from_string(days_since_ath[:-14], "%Y-%m-%d") print('days since ath formatted', days_since_ath_formatted) crypto_data_geckco.append(currency_gecko) print("crypto_data_geckco", crypto_data_geckco) return render(request, 'crypto/latest.html', { 'crypto_data_geckco': crypto_data_geckco, 'days_since_ath_formatted': days_since_ath_formatted} ) and then on the Django template: {% for currency in crypto_data_geckco %} All-Time Percentage: {{ currency.ath_change_percentage|intword … -

Python Django: Customize Admin Startpage as analytical Dashboard
I am currently developing a mobile app using Ionic and I am using Django Admin Interface as sort of Backend for adding and editing the content of my mobile app through a MySQL Database. I currently wish to create a custom analytical dashboard for tracking the usage of the users of my mobile app in the startpage of the Django Admin. While there are some analytical packages for tracking the usage in Django, they only function for web applications. In my case I need to gather and display aggregate data from my database (Django models & not Django models) as well for other APIs. Is there a way how can I fetch data in form of SQL queries and display them in my dashboard using Python (Django)? And how can I extend the starting page of Django Admin to a full analytical dashboard with the named functionalities? I am currently struggling with this as I am new to Django.

Django. IntegrityError: NOT NULL constraint failed: MyApp_song.albums_id
For starters, I just started learning Django. I'm trying to add a new song object to my album via the form.

Instead, I want the value of my foreign key to be set depending on the album I'm adding a new song from. How can i do that in Django?

So i'm getting this error. Maybe you know what's the problem? Thanks, any help will be appreciated! -
How do I upgrade an old Django Google App Engine application to a Second Generation Cloud SQL Instance?
I have a Django application that I wrote 5 years ago, which has been running successfully on Google App Engine - until last month when Google upgraded to Second Generation Cloud SQL. Currently, I have a settings.py file, which includes a database definition which looks like this: DATABASES = { 'default': { 'ENGINE': 'google.appengine.ext.django.backends.rdbms', 'INSTANCE': 'my-project-name:my-db-instance', 'NAME': 'my-db-name', }, Google's upgrade guide, tells me that the connection name needs to change from 'my-project-name:my-db-instance' to 'my-project-name:my-region:my-db-instance'. That's simple enough. Changing this leads me to get the error InternalError at /login/ (0, u'Not authorized to access instance: my-project-name:my-region:my-db-instance') According to this question, I need to add the prefix '/cloudsql/' to my instance name. So, I changed this (and the ENGINE specification) to give: DATABASES = { 'default': { 'ENGINE': 'django.db.backends.mysql', 'INSTANCE': '/cloudsql/my-project-name:my-region:my-db-instance', 'NAME': 'my-db-name', 'USER' : 'root', 'PASSWORD': '******************', }, I uploaded the modified file to Google (using gcloud app deploy). This time I get a completely different error screen, showing: Error: Server Error The server encountered an error and could not complete your request. Please try again in 30 seconds. When I look in the Logs, I see: ImproperlyConfigured: Error loading MySQLdb module: No module named MySQLdb It was pointed out … -
