Why I see no Django log in git-bash?
I am using Python 3's print to log from Django dev server. I should mention that I also tried to configure Django to use the Python logger but without much luck. I am using pipenv run but the same happens when I activate the virtual env using pipenv shell. I have a very simple view: from django.shortcuts import render def index(request): print('Printing to the console from myapp.views.index') return render(request, 'myapp/index.html', { 'message': 'Hello, World!' }) While everything works perfectly fine in cmd.exe, git-bash does not display any output from my custom logging. See image below. Why is that? Does it have to deal with the fact that one console is considered a terminal (tty) and the other is not? -
Django to create a website that performs various analytics using a document?
I am new to Django and I created a website which show the frequent word count in a given document(.pdf, .word) in views.py using chart.js as a bar chart. So, my question is I want to create multiple tabs which uses the same file and perform some analysis like text summarization, NER(I do have code for that) and return the result in another tabs. The problem I am facing here is when I return the value of a function in views.py and input that value in a html file it can take the data and I can create bar charts, so when I create another function(so that I can input this function's value in another tab as I previously mentioned) and add a new jquery block it says two jquery blocks are not allowed. What might be the issue and is there any process to create a django website to perform various analytics using a single document. Thanks in advance! -

Django "NULLS LAST" for creating Indexes
Django 1.11 and later allow using F-expressions for adding nulls last option to queries: queryset = Person.objects.all().order_by(F('wealth').desc(nulls_last=True)) However, we want to use this functionality for creating Indexes. A standard Django Index inside a model definition: indexes = [ models.Index(fields=['-wealth']), ] I tried something along the lines of: indexes = [ models.Index(fields=[models.F('wealth').desc(nulls_last=True)]), ] which returns AttributeError: 'OrderBy' object has no attribute 'startswith'. Is this possible to do using F-expressions in Django? -

How to modify get_queryset result value

NoReverseMatch from url tag inside include tag
I am trying to render a link inside an include html template with the url tag. I have done this before and usually it works, but for some reason this time I can't make it. I get a NoReverseMatch Error and suspect its because Django tries to load the url tag first but my object isn't ready, so the pk is empty. I believe that because it takes a moment until the dynamic data loads, while the static is already loaded. The url works if I set pk to a fixed number, but I would like it to change dynamically.

Django ModelForm.save() not working
I'm trying to add a comment to a database through a ModelForm but then the website just refreshes and nothing is actually saved in DB (confirmed it on the admin page). Also manually adding a comment through admin page works fine, so the problem probably lies in form mechanics. form class CommentForm(ModelForm): class Meta: model = Comment exclude = ['episode'] model class Comment(models.Model): autor = models.CharField(max_length=30) text= models.TextField(default='') data = models.DateField(auto_now_add=True) episode= models.ForeignKey(Episode, on_delete='Cascade', related_name='comments') view def episode(request, numer): episode = Episode.objects.get(numer=numer) comments = Comment.objects.all() if not request.method == 'POST': form = CommentForm() if request.method == 'POST': form = CommentForm(data=request.POST) if form.is_valid(): new_comment = form.save(commit=False) new_comment.episode= episode new_comment.save() I know there are some similar topics already, but none of them actually solves my issue. Also didnt find any mistakes according to the docummentation. -
