Django APIView data format from AJAX
I was trying to send an array of objects in views.py using APIView to insert multiple rows in 1 post request. This is my JavaScript data format: const data = { group_designation: [ {id: 1}, {id: 2}, {id: 3}, ] } I run an insomnia app and it only accepts this kind of format: { "group_designation": [ {"id": 1}, {"id": 2}, ] } However, if I send a post request using the javascript format stated above, it gives me a bad request error(400). This is the payload in network tab: group_designation[0][id]: 1 group_designation[1][id]: 2 group_designation[2][id]: 3 In Django, this is the request.data result: <QueryDict: { 'group_designation[0][id]': ['1'], 'group_designation[1][id]': ['2'], 'group_designation[2][id]': ['3'] }> My code in Django: def post(self, request): temp_objects = [] new_data_format = {'group_designation': temp_objects} serializer = GroupSerializer(data=new_data_format, many=True) if serializer.is_valid(raise_exception=True): group_data_saved = serializer.save() return Response({ "success": "success!!!" }) I was just trying to rewrite the data format so it will be saved but no luck trying. Please help. Thank you! -
Use pipenv with django heroku
So I began to code a project with python, and I was using a tutorial that told me to use a pip environment as my virtual environment. A problem arose, however, when I performed the git push heroku master command. It could not find the package django-heroku! I was confused, because when I ran python manage.py runserver, the server on my computer ran. I later realized that the problem was that the pip environment was located in a .virtualenvs folder that was outside of the folder I was pushing to heroku. I then changed to a python environment, which was located in the directory I was pushing to heroku. The problem was solved! The virtual environment, and consequently the installed packages, were inside the directory being pushed to git, and I could use them in my website! But the question still remains: can you use a pip environment for a django project being pushed to git? Thanks! -
How to display error when using is_active for Login
I set a user.is_active to false so they can't login. user.is_active=False user.save() I would like to override the login section to show that the account has been disabled.

How to prevent Django save action to avoid repetitive DB calls on already existing data
My current code for saving articles saves new articles and prints 'The Post Already Exists!' if a duplicate is found, but it's still making DB calls and so now I have ID gaps in my articles table because of the false saves caused by duplicate articles not being saved. How can I improve my code to prevent the save action if a duplicate is found to preserve consistency in my article IDs? if not Posts.objects.filter(title=post_title, slug=post_slug).exists(): post = Posts( title = post_title, link = post_link, summary = post_summary, image_url = image_link, slug = post_slug, pub_date = date_published, guid = item.guid, feed_title = channel_feed_title, feed_link = channel_feed_link, feed_description = channel_feed_desc, source_id = selected_source_id, category_id = selected_category_id ) post.save() for i in range(len(article_list)): post_tags = post.tags.add(article_list[i]) else: print("The Post Already Exists!

Django POST is missing positional argument
I'm bypassing the use of a model to get basic filter responses for presentation purposes from the user. Accordingly, I've defined a cardsStatsForm class as below: forms.py from django import forms class cardStatsForm(forms.Form): def __init__(self, filterList, sortList, *args, **kwargs): super(cardStatsForm, self).__init__(*args, **kwargs) self.fields['filts'].choices = filterList self.fields['filts'].label = "Select player rankings for inclusion in statistics:" self.fields['sorts'].choices = sortList self.fields['sorts'].label = "Choose a sort order:" filts = forms.MultipleChoiceField(widget=forms.CheckboxSelectMultiple, choices=(), required=True) sorts = forms.ChoiceField(choices=(), required=True) Unfortunately, when I retrieve the POST command, I am getting a positional argument error. I am confused, however, because I thought the point of the POST is to retrieve values. So why does "post-POST" code typically run the class instance? If i were to submit a positional value, would it not be overwritten by this statement? Isn't request.POST a form of "self" statement? views.py @login_required() def cards(request): f_name = STAT_FILES / 'csv/segment_summary_quart.csv' # pathname = os.path.abspath(os.path.dirname(__file__)) df = pd.read_csv(f_name, index_col=None) pl_name = STAT_FILES / 'pickles/lbounds' pu_name = STAT_FILES / 'pickles/ubounds' lbounds = pickle.load(open(pl_name, "rb")) ubounds = pickle.load(open(pu_name, "rb")) filter_name = [] i = 0 max_i = len(ubounds) while i < max_i: filter_name.append(f'Personal best trophy range: {str(int(lbounds[i])).rjust(4," ")}-{str(int(ubounds[i])).rjust(4," ")}') i += 1 filter_id = range(len(filter_name)) filter_list = list(zip(filter_id, filter_name)) … -
Django " ImproperlyConfigured:"
I have created a blog with django by following some book. The django website works but the terminal keeps on showing this message if i try to interpret the code on spyder(setting.py, models.py) ImproperlyConfigured: Requested setting INSTALLED_APPS, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings. Here ImproperlyConfigured: You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings the solution which was given for this was: set DJANGO_SETTINGS_MODULE=mysite.settings as in the documentation for django. However if i stop the server and restart it after running the code i am still getting the same error. Could you please advise what setting it is referring to which are not configured? This is perticularly odd because it prints out the same error message if I run this help(models.DateTimeField) -
