TypeError: academic() missing 1 required positional argument: 'request'
I can not pass request to views.py to serializers.py.

Please help me to pass the request inside the is_academic = views.academic(request) Or tell me any way to pass the request. -
Github Actions running 0 tests
I have three tests in my Django project which get executed running "python manage.py test appname" locally. However, Github Actions runs zero tests, returning no errors. How can I fix this?

creating an email-defined user in django
I am creating a simple web app in django in which users are identified by their email and not a username. I've been following the guide: https://www.fomfus.com/articles/how-to-use-email-as-username-for-django-authentication-removing-the-username/ And it works fine!

django collectstatic picking files from wrong location
I am beginner in Python and Django. I am using Windows10 and I have installed Python 3.10.0 and pip 21.3.1. I installed Django using following commands pip install virtualenvwrapper-win mkvirtualenv firstdjango pip install django django-admin startproject demo then I created APP for just simple static HTML page and now I am trying to use static files. I created a folder having name "static" on root and placed all css, js etc files in it and in settings.py, I mentioned following. STATIC_URL = '/static/' STATICFILES_DIR = [ os.path.join(BASE_DIR, 'static') ] STATIC_ROOT = os.path.join(BASE_DIR,'assets') Now when I hit python manage.py collectstatic then it is not copying, what is in my static folder to assests folder. When I tried to check from where collectstatic is trying to copy using following command python manage.py findstatic -v 3 dummy then I got following C:\Users\dell\Envs\firstdjango\lib\site-packages\django\contrib\admin\static but my project location is E:\django\demo I am not getting, why collectstatic is not able to copy correct files and hence I do not get correct paths of my css, js and images in my web page. -
How to avoid that Django adds url link to every html element that follows the link
i would like to achieve something very basic in Django but can't find out what I am doing wrong. On my apps "index.html", I would like to add a button which redirects to another html template ("site.html") with other content. I added the following to "index.html" which is working: <body> <h2>foo</h2> {% block content %} <button><a href="{% url 'site' %}"/>Click</button> {% endblock %} <p>bar</p> </body> Clicking on the button gets me to "site.html", however all html items which I add on "index.html", for example the paragraph "bar" would also get rendered as hyperlink. I tried creating different Django blocks or making different html sections but that doesn't fix it. Thank you for your help. -

django validate values for calculation
Hej! I need to do some simple calculations of filtered data in my django view. This works just fine when having values in the chosen filter. If the value is 0 or None I get an server error and the site collpases. Therefore I need a validator to make sure the given value is not 0 and not None. (my attempt is at the bottom) Currently if the validator is added it gives me the message that 'float' object is not callable, even before getting to the filter option/template. And: in my model is a m2m to the model where I get the values from. For each value can a unit be chosen and I only want to calculate if the units are identical, otherwise I want to get a warning. Does anyone knows how to achieve that? Or where to look? Any help is appreciated! :) # validators.py def validate_values(value): if value == 0: raise ValidationError(_('One of the given values is 0 or empty and the calculation therefore cannot be proceeded.'), code='notinrange') # views.py def process_mass_intensity(request): plants = Plant.objects.all() myFilter = PlantsNameFilter(request.GET, queryset=plants) plants = myFilter.qs total_m = plants.aggregate(Sum('used_in_plant__value'))['used_in_plant__value__sum'] product_m = plants.aggregate(product_mass=Sum('used_in_plant__value', filter=Q(used_in_plant__input_or_output='OUT')))['product_mass'](validators=[validate_values]) pmi = (total_m / product_m)(validators=[validate_values]) context … -

is there any way or package by which we can perform filters(searching) on custom raw sql query in django?
I read the below document : https://docs.djangoproject.com/en/3.2/topics/db/sql/ in model there are lots of filter lookup available like field__gt, field__lt, field__range, field__contains but i want to use these into raw sql like suppose query = SELECT * FROM customers WHERE customers.name like '%name%' and age < 30 and status IN ('active','pending') Here : customers.name like '%name%' name would be user input so i want to protect it from sql injection as well as filter it using % operator age < 30 30 would be user input, and want to perform < > = also IN ('active','pending') want to pass list of string using IN operator is there any proper way/package available by which we can run raw sql preventing sql injection as well as filtering data using %, IN, <, >, = operators. -
how to automatically redirect the user to a specific language in django
I have added new languages to my website and now it is available in English, French and Arabic Everything works fine, I couldn't figure out how to change the default language Currently when the user does not select any language, the site is displayed in English. Some users are complaining that English is not widely used in my country and the site should be in Arabic instead, so I want to do this: if the user does not select any language it will be redirected automatically to arabic. So when i visit my website like this: http://127.0.0.1:8000/ i will be automatically redirected to: http://127.0.0.1:8000/ar/ Is it possible to do something like this or do I have to change the default code for the whole website. i have this code in urls.py urlpatterns = [ path('admin/', admin.site.urls), path('',include('core.urls')), path('user/',include('users.urls')), path('dashboard/',include('dashboard.urls')), path('wallet/',include('wallet.urls')), path('administration/',include('administration.urls')), path('chaining/', include('smart_selects.urls')), path('__debug__/', include(debug_toolbar.urls)), ] urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) urlpatterns += i18n_patterns ( path('',include('core.urls')), path('user/',include('users.urls')), path('dashboard/',include('dashboard.urls')), path('wallet/',include('wallet.urls')), path('administration/',include('administration.urls')), ) and this is my settings from django.utils.translation import gettext_lazy as _ LOCALE_PATHS = ( os.path.join(BASE_DIR, 'locale'), ) LANGUAGE_CODE = 'en' LANGUAGES =( ('en', ('english')), ('ar', ('Arabic')), ('fr', ('french')) ) -

Angular to Django, passing multiple parameters in a service call
I have some working code on Django, where i created a simple file uploader with a date picker that is passed through a view and then uploaded onto a database using a standalone python class that utilise sqlalchemy. However, I have been working on migrating the UI aspect onto an Angular Front End, but hit a road block and not sure where I am going wrong. The user needs to be able upload a excel binary file, input a date and hit upload. This should send a request to a view which then handles the request. The view it self works perfectly, when the file and dates are inputted from the Django HTML template. But I can't seem to make it work once the inputs come from Angular. At the moment I am getting a 'Unsupported Media Type" Error message. But my guess is i am not passing the file and date correctly to the service.

Django Admin get_fieldsets kills User add form. Cannot add User
All hands, what I was trying to do is to filter UserChange fieldsets on the basis of user access. Just to remove some fields if user is not superuser And it worked. However later I discovered that I cannot create User as the start form with user name and two password fields is non existent anymore. So, Django keeps showing me red sign of mistakes as simply there are not required fields visible and I cannot fill them up. I removed all my code and found out that the simple fact of having this get_fieldsets function changes the add_form I tried to add specific user add form, I tried add_fieldsets - everything with no result until I have get_fieldsets() in my UserAdmin. Any ideas what I am doing wrong? -
