Graph Generated By Chart.js Has Entirely Different Coordinates
I am trying to sketch out a real-time graph in Django and I deployed Chart.js functions' to help me out. What I did was to return a dictionary containing the points that I would like to plot within the script tag. The keys of the dictionary will be assigned to the "label" field while the values to the "data" field. However, the points that were plotted out were completely different from the dictionary that I provided and on top of that extra points kept appearing out of nowhere which didn't seem to cease until I manually stopped the process. Below is a portion of the html code: <div class="centerpane"> <canvas id="myChart" width="400" height="200"></canvas> </div> <script > var ctx = document.getElementById('myChart').getContext('2d'); 'use strict'; var main_graph_points = "{{ main_graph_points }}"; //the dictionary var graphData = { type: 'line', data: { labels: Object.keys(main_graph_points), datasets: [{ label: 'main graph', data:Object.values(main_graph_points), backgroundColor: [ 'rgba(73, 198,230, 0.5)', ], borderWidth: 1 }], options:{ scales: { xAxes: [{ type: 'category', }] } }, }, } var myChart = new Chart(ctx,graphData ); var socket = new WebSocket("ws://localhost:8000/ws/mysite/"); socket.onmessage = function(e){ var djangoData = JSON.parse(e.data); console.log(djangoData); document.querySelector("#app").innerText = djangoData.value; }</script> //contents of the dictionary main_graph_points={20: 59.96601343154907, 24: 59.89738027254739, 28: 59.9285344282786, … -

Bootstrap: reduce horizontal spacing between cards when using card-columns class
I'm attempting to render several rows of Bootstrap cards, with each row having two cards side-by-side. My code is working, but there is lots of space between the cards when the screen is expanded. Here is the code: HTML (uses Django template) {% block body %} <h2>{{ title }}</h2> <div class="container-fluid"> <div class="card-columns mx-auto col-10"> {% for entry in entries %} <div class="mx-auto card h-100 mb-3" style="max-width: 480px"> <a href="{% url 'listing' listing.id %}"> <img class="card-img-top" src="{{ entry.image.url }}" alt="{{ entry.title }}"> </a> <div class="card-body"> <h5 class="card-title">{{ entry.title }}</h5> <p class="card-text">{{ listing.description }}</p> </div> </div> {% empty %} No content found. {% endfor %} </div> </div> {% endblock %} CSS: body { min-height: 100vh; background-color: #ecf1f4; } .card-columns { column-count: 2; column-gap: 20px; /* does not affect the spacing! */ justify-content: center; flex-wrap: wrap; display: flex; } @media (max-width: 500px) { .card-columns { column-count: 1; } } The column-gap does not affect the spacing. Is this being overridden by something else? Or, is there another mistake, perhaps? Thanks in advance for any advice you can give this CSS newbie! -
django.db.utils.ProgrammingError: Column does not exist
I have a model class that inherits from two abstract models: # cars app class Car( PolymorphicModel, BaseSyncModel, ): """Car parent model.""" id: models.UUIDField = models.UUIDField( # noqa: A003 primary_key=True, default=uuid.uuid4 ) store: models.ForeignKey = models.ForeignKey( CarStores, on_delete=models.CASCADE ) price: models.IntegerField = models.IntegerField() year: models.IntegerField = models.IntegerField( validators=[MinValueValidator(1900), MaxValueValidator(2021)], ) brand = models.TextField("Car's brand") It inherits from the PolymorphicModel and from a class to make sync, it is like that: class BaseSyncModel(models.Model): updated_at = models.DateTimeField(auto_now=True, editable=False) class Meta: abstract = True My problem is, when I pushed it to GitHub, the CI raised the following error: django.db.utils.ProgrammingError: column "updated_at" of relation "cars_car" does not exist I think it is related to the multiple inheritances because the other classes that don't inherit from PolymorphicModel didn't raise the same error. I have no idea how to proceed with that. -

Remove underline from href attribute that reference a Django template
At the top of one of my website pages, I have some text representing the name of my company. When the user clicks the text (a link in this case), they are redirected to the index route via the Django template. Currently, the text is decorating.
