Django - how to make a CloudinaryField not mandatory and how to allow user to delete their uploaded image?
Hej, I am just beginning to learn Django and I want my users to be able to upload a profile picture, so I extended the User model with a Profile model, however, so far I have not figured out how to make the image upload non-mandatory. And when the user has added a picture, I would like them to be able to remove it as well. Screenshot - Not able to Submit without adding file Screenshot - Not able to remove the added file models.py class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) bio = models.TextField() profile_image = CloudinaryField('profile_image') def __str__(self): return self.user.username forms.py class ProfileForm(ModelForm): class Meta: model = Profile fields = ('bio', 'profile_image',) views.py @login_required(login_url='login') def createPost(request): form = PostForm() if request.method == "POST": form = PostForm(request.POST, request.FILES) # request.FILES necessary so that file is submitted # also required to add enctype to the form if form.is_valid(): post = form.save(commit=False) post.author = request.user post.save() return redirect('home') context = {'form': form} return render(request, 'my8gag/post_form.html', context) Couldn't find anything about this in the documentation or here on SO, so would appreciate any kind of help/hints! Thanks in advance. -

How to make your custom django migrations reversible?
My original problem was, given a db table with 60M rows I need to convert a field type from boolean to integer field. I thought of creating a custom django migration for this (please do let me know if you have a better approach than this) which looks like this- def make_changes(apps, schema_editor): vcs_model = apps.get_model('iot_app', 'AbstractVCSCompartmentData') vcs_model.objects.select_related('vcsdata').all().update(charging_status_v2=F('charging_status')) vcs_model.objects.select_related('vcsdata').all().update(charging_status_backup=F('charging_status')) # backup class Migration(migrations.Migration): dependencies = [ ('iot_app', '0030_auto_20220225_1027.py'), ] operations = [ migrations.AddField( # backup field model_name='AbstractVCSCompartmentData', name='charging_status_backup', field=models.PositiveIntegerField(blank=True, null=True), ), migrations.AddField( model_name='AbstractVCSCompartmentData', name='charging_status_v2', field=models.PositiveIntegerField(blank=True, null=True), ), migrations.RunPython(make_changes), migrations.RemoveField( model_name='AbstractVCSCompartmentData', name='charging_status', ), migrations.RenameField( model_name='AbstractVCSCompartmentData', old_name='charging_status_v2', new_name='charging_status', ), ] I want to unroll all the changes i.e., making my custom migration reversible. I have gone through RunPython doc. But I am confused as in how can i perform addition of a new field in my reverse_code() function. The idea of creating a backup field is to reinstate the db to its previous state. -

Why is my Python path configuration not changing in Apache
I am trying to setup Apache 2.4 on Windows to work with a Django project. As a first try, I made just a base application showing the "welcome-rocket" of Django. After configuring the httpd.conf file of Apache, the well knwon error ModuleNotFoundError: No module named 'encodings' appears. I tried out all suggestions from here. Sadly, none of the ideas had an effect. I ended up using the following line in the config file: LoadFile "C:/Python/Python37/python37.dll" LoadModule wsgi_module "D:/Projects/TestProject/venv/lib/site-packages/mod_wsgi/server/mod_wsgi.cp310-win_amd64.pyd" WSGIPythonHome "D:/Projects/TestProject/venv/Scripts" WSGIPythonPath "D:/Projects/TestProject/venv/Lib;D:/Projects/TestProject/venv/Lib/site-packages;C:/Python/Python37/DLLs" WSGIScriptAlias / "D:/Projects/TestProject/venv/backend/backend/wsgi.py" During this process, I noticed that the python path configuration printed to the error.log file never changed, no matter which paths I used in the lines above. Here is a snippet from the log: Python path configuration: PYTHONHOME = (not set) PYTHONPATH = (not set) program name = 'python' isolated = 0 environment = 1 user site = 1 import site = 1 sys._base_executable = 'C:\\Apache24\\bin\\httpd.exe' sys.base_prefix = 'C:\\Users\\myuser\\AppData\\Local\\Programs\\Python\\Python310' sys.base_exec_prefix = 'C:\\Users\\myuser\\AppData\\Local\\Programs\\Python\\Python310' sys.platlibdir = 'lib' sys.executable = 'C:\\Apache24\\bin\\httpd.exe' sys.prefix = 'C:\\Users\\myuser\\AppData\\Local\\Programs\\Python\\Python310' sys.exec_prefix = 'C:\\Users\\myuser\\AppData\\Local\\Programs\\Python\\Python310' sys.path = ['C:\\Users\\myuser\\AppData\\Local\\Programs\\Python\\Python310\\python310.zip', '.\\DLLs', '.\\lib', 'C:\\Apache24\\bin', ] Fatal Python error: init_fs_encoding: failed to get the Python codec of the filesystem encoding Python runtime state: core initialized ModuleNotFoundError: No module named 'encodings' … -

How to make a global filter in Django admin?
Is it possible to make a global filter in the admin panel? For example, there are models: class Company(models.Model): name = models.CharField( 'Name company', max_length=200, help_text='Name company' ) city = models.CharField( 'City', max_length=200, help_text='City' ) class Object(models.Model): name = models.CharField( 'Name object', max_length=200, help_text='Name object' ) number = models.CharField( 'Number object', max_length=200, help_text='Number object' ) company = models.ForeignKey( Company, on_delete=models.SET_NULL, verbose_name='Company', null=True ) class Person(models.Model): name = models.CharField( 'Name, max_length=200, help_text='Name' ) number = models.CharField( 'ID person', max_length=200, help_text='ID person' ) object = models.ForeignKey( Object, on_delete=models.SET_NULL, verbose_name='Object', null=True ) It turns out that there are several companies. Each company has several facilities, which in turn have staff. I want to make a global filter by Companies in the admin panel. That is, not to filter every time, but let's say I chose the company "Horns and Hooves" and calmly worked in the admin area with objects belonging to this company. This is just an example, in reality there are many more models -
