Check if the last file in os.listdir()
I need to know if the file currently checked in the os.listdir is the last file. I need it in a condition I have. Here is the code: # iterate through all files in directory for filename in os.listdir(edgar_path): # open and read with open(edgar_path + filename, 'r') as file: # rearrange by date (column 3) tsv_file = sorted(list(csv.reader(file, delimiter='|')), key=lambda t: t[3]) # get date today today = datetime.datetime.now() # get start date and end date depending on the first and last row start_date = datetime.datetime.strptime(tsv_file[0][3], "%Y-%m-%d") end_date = datetime.datetime.strptime(tsv_file[len(tsv_file) - 1][3], "%Y-%m-%d") # check print logger.debug(start_date) logger.debug(end_date) # if within date range if start_date <= today <= end_date: logger.debug('pass condition 1') # if not within date range, but # the date today is greater than the end date # and its the last file being checked so it still passes elif today >= end_date: logger.debug('pass condition 2') # add to delete files if both conditions are unmet else: files_to_delete.append(filename) logger.debug('no pass') Any help is appreciated. -

Pure CSS radial timer with Django
I know that it's possible to create timed animations in pure CSS, and I've been able to get a 5 minute radial timer working in CSS the way I'd like. I'm just getting started with Django, and I'm curious whether I can make this functional for users. If someone visits my page, would Django be able to pull their visit time and pass it to the CSS animation, so that the animation is at the same point in the progression for all visitors? Is there any way to make the animation progression persistent upon page refresh as well? I'm very interested to know if there is any JavaScript-free solution to this, even if it is unwieldy. -

What is the best way to create a 'list' associated with a model?
I want to be able to associate a company name in my models with a list of 'milestone' percentage points, in order to calculate how far each company is from the nearest milestone. For example: List_Of_Milestones = [5, 10, 15, 20, 25] Current_Progress = 9.5% Example Output = "Company A is 0.5% away from the 10% milestone, and 4.5% above the 5% milestone." The logic is simple from a Python standpoint, but I can't get my brain around how I would create this in a model setup and allow the user to set their own list of milestones. -

Using Jinga2 Loop Control extension
I would like to break out of a for loop in a template. I understand this is not possible in DTL, but according to the docs it is possible if using Jinja2 (with the Loop Control extension) as the template engine. So I have updated my settings.py to include { 'BACKEND': 'django.template.backends.jinja2.Jinja2', 'DIRS': [os.path.join(BASE_DIR, 'templates/jinja2')], 'APP_DIRS': True, 'OPTIONS': { 'environment': 'project4.jinja2.environment'}, }, I define the Jinja environment in jinja2.py: from jinja2 import Environment from django.contrib.staticfiles.storage import staticfiles_storage from django.urls import reverse def environment(**options): env = Environment(**options, extensions=['jinja2.ext.loopcontrols']) env.globals.update({ 'static': staticfiles_storage.url, 'url': reverse, }) return env In my views.py is point to the jinja template file: return render(request, "jinja2/index.html", { "pages": page_obj, "liked": liked_posts }) But when I try to use the break statement in my loop like so: {% for like in liked %} {% if like.liked_post == page %} <span><button class="btn btn-secondary" id="unlike">Unlike</button></span> {% break %} {% else %} <span><button class="btn btn-secondary" id="unlike">Like</button></span> {% endif %} {% endfor %} I receive the following error: Invalid block tag on line 30: 'break', expected 'elif', 'else' or 'endif'. Did you forget to register or load this tag? What am I missing? Should the Jinja2 environment be be created in my views.py? -

check if quiz time ended in django
I want to check if time if the quiz is ended while the user is answering the quiz and if time is finished user will be redirected to another page the problem is that I can't find a way to start the check process without reloading the page if there is a way to make it work or if there is another way better than this I am all ears thanks in advanced models.py class Quiz(models.Model): name = models.CharField(max_length=30) start_date = models.DateField(null=True, blank=True) start_time = models.TimeField(null=True, blank=True) duration = models.IntegerField(null=True,blank=True) quiz_images = models.ImageField(upload_to=PathAndRename("images\\quiz_images"), default="images\\quiz_images\\default.png") slug = models.SlugField(max_length=8, null=True, blank=True) course = models.ForeignKey(Course, on_delete=models.CASCADE) prof = models.ForeignKey(User, on_delete=models.SET_NULL, null=True,limit_choices_to={'is_prof':True}) class Meta(): constraints = [ models.UniqueConstraint(fields=['name','course'],name='unique course') ] def __str__(self): return f"{self.name}/{self.course.name}" def save(self, *args, **kwargs): if not self.slug: self.slug = slug_generator(self) super().save(*args, **kwargs) image_resize(self.quiz_images.path) def get_absolute_url(self): return reverse('create-quiz-question', kwargs={'slug': self.slug}) @property def get_end_time(self): q_time=datetime.combine(self.start_date,self.start_time) return q_time+timedelta(minutes=self.duration) @property def is_open(self): if datetime.utcnow() > self.get_end_time: return False return True @property def get_quiz_grade(self): total = 0 for question in self.questions.all(): total += question.grade return total views.py def quiz_view(request,slug): quiz = Quiz.objects.filter(slug=slug).first() form = AnswerQuizForm(questions=quiz.questions.all()) # if not quiz.is_open: # if form.data: # form = AnswerQuizForm(data=request.POST,questions=quiz.questions.all(),user=request.user) # if form.is_valid(): # attemp=form.save() # attemp.quiz=quiz # attemp.save() …
