How to get the name of the month instead of the month number from db
I am picking some data from the db to make some analytics in my website. I am rendering out the data graphically with the help of chart js. This is how I am doing it in views, views.py monthly_visitor = VisitorCount.objects.all().filter(date_of_record__year = currentYear.year).values( 'date_of_record__month' ).annotate( total_in_month=Count('ip') ).order_by('date_of_record__month') Here, I am picking up the data of all the visitors of every month of the current year. Now if I print the monthly_visitor I get the below result <QuerySet [{'date_of_record__month': 9, 'total_in_month': 1}, {'date_of_record__month': 10, 'total_in_month': 2}, {'date_of_record__month': 11, 'total_in_month': 3}, {'date_of_record__month': 12, 'total_in_month': 5}]> Which is correct but what I want is <QuerySet [{'date_of_record__month': sept, 'total_in_month': 1}, {'date_of_record__month': oct, 'total_in_month': 2}, {'date_of_record__month': nov, 'total_in_month': 3}, {'date_of_record__month': dec, 'total_in_month': 5}]> So that I can display names of the month in the graph rather the numbers. I came across some methods to use tags in the html. But I am importing this data into a different javascript file with the help of ajax. Please suggest me what should I do. -
Python Django html templating
I'm building a web portfolio for albums photography and others features, but the html templating is a bit messy for me, I have few diferents questions related to this subject.

But my problem is that this code is in the base.html that I extend everywhere. I know I can modify this with {% block sidebar %}, but this informations need to be in all templates too. If I'm right I can't send data to the base.html to populate the list ? Is there a way to achieve this without copy/paste code into all html templates? If needed, my request … -

How to default language - error in changing it - Django
I have been struggling for quite a while with translation in django. I want to set a default language that is being set everytime user access the website (in a new session). I have studied django documentation, and I found the following algorithm: First, it looks for the language prefix in the requested URL. This is only performed when you are using the i18n_patterns function in your root URLconf. See Internationalization: in URL patterns for more information about the language prefix and how to internationalize URL patterns. Failing that, it looks for a cookie. The name of the cookie used is set by the LANGUAGE_COOKIE_NAME setting. (The default name is django_language.) Failing that, it looks at the Accept-Language HTTP header. This header is sent by your browser and tells the server which language(s) you prefer, in order by priority. Django tries each language in the header until it finds one with available translations. Failing that, it uses the global LANGUAGE_CODE setting. So I am trying to set the language prefix in the requested URL. I have configured my app as follows: settings.py MIDDLEWARE = [ 'django.middleware.security.SecurityMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.locale.LocaleMiddleware', 'django.middleware.common.CommonMiddleware', 'django.middleware.csrf.CsrfViewMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware', 'django.middleware.clickjacking.XFrameOptionsMiddleware', 'crm.middleware.RequestMiddleware', ] ....

How to store static file on Google cloud storages using heroku deployment?
I used whitenoise to save static files, but now I want to save them to Google cloude storage. So I reset dyno and set it as follows, but the static folder is not created in storage. I'm not sure what I'm missing. google_credential is working well. The upload file is well stored. The level is also done without problems. However, static files are not generated in GCS. settings.py configuration if DEBUG is False : ALLOWED_HOSTS = ["cineacca.herokuapp.com", 'cineacca.com',] GOOGLE_APPLICATION_CREDENTIALS = os.environ.get("GOOGLE_APPLICATION_CREDENTIALS") DEFAULT_FILE_STORAGE = "config.custom_storages.UploadStorage" STATICFILES_STORAGE = "config.custom_storages.StaticStorage" STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles') GS_DEFAULT_ACL = "publicReadWrite" GS_BUCKET_NAME = "cineacca_bucket" GS_PROJECT_ID = os.environ.get("GS_PROJECT_ID") MEDIA_URL = "/media/" STATIC_URL = "/static/" django_heroku.settings(locals()) custom_storages.py from storages.backends.gcloud import GoogleCloudStorage from storages.utils import setting class StaticStorage(GoogleCloudStorage): bucket_name = setting('GS_BUCKET_NAME') location = "static/" class UploadStorage(GoogleCloudStorage): bucket_name = setting('GS_BUCKET_NAME') location = "uploads/" -
Button type "submit" doesn't let bootstrap modal to open but type="button" doesn't fulfill my need
I have a web page in which there is an input field. And below is an edit button. When I enter some text in the input field and press the edit button, a modal pops up and there is an input field in it also. I want to pass the text from the first input field to the input field in the modal window. But then a problem arises. The modal window only opens when the edit button has type="button". But this type="button" doesn't submit the text input to the backend when I click the edit button. It submits the text to the backend when I use button type="submit", but then the modal doesn't open because the page reloads. Here's my HTML code: <div class="container"> <div class="row manage-groups"> <div class="row g-0 login_form justify-content-center" id="contactForm" novalidate="novalidate"> <form method="POST"> {% csrf_token %} <div class="col-md-12 form-group"> <input type="text" class="login-inpt" id="name" name="type-groups" placeholder="type in the group name"> </div> <div class="row g-0 justify-content-center group-action"> <div class="col-sm-4 submit-group"> <div> <button type="submit" data-bs-toggle="modal" data-bs-target="#ModalAddGroups" class="button-box">Add</button> </div> </div> <div class="col-sm-4 submit-group"> <button type="button" onclick="form_submit()" data-bs-toggle="modal" data-bs-target="#ModalEditGroups" class="button-box">Edit</button> </div> <div class="col-sm-4 submit-group"> <button type="submit" data-bs-toggle="modal" data-bs-target="#ModalDeleteGroups" class="button-box">Delete</button> </div> </div> </form> </div> </div> </div> <!-- Modal window for Edit button …
