404 Page not found Django even though it is in urls.py
I don't know why I am getting a 404 error on the page flights/1 when clearly, I have a url pattern for <int:flight_id> (flights is a app). Help!

How to implement a like system in Django templates
I am currently working on building a "like" system for a blog-style website in Django. I've been looking at several different examples for setting up the HTML templates and was hoping to better understand some of the logic. My first thought was to tie the "like" button to the corresponding view like so: <a class="btn btn-secondary" href="{% url 'post-like' post.id %}" role="button">Like ({{ post.likes.count }})</a> This seemed to work decently well (the "like" was registering and showing up in the count) but I was having trouble getting back to the right page after clicking the "like" button (i.e. when I clicked "like" it took me to some other page vs. staying on the home page). I then found another example online that created a get_like_url() function under the broader Post Model like this: def get_like_url(self): return reverse("post-like", kwargs={"pk":self.id}) And then called it in the template like this: <a class="btn btn-secondary" href="{{ instance.get_like_url }}" role="button">Like ({{ post.likes.count }})</a> I thought this was basically doing the same thing but when I used this method it would return me to the home page of my site but wouldn't register the like (i.e. didn't seem like the button actually did anything). Could anyone help … -
Is there a way to solve this ValueError in my django app?
I’ve created a school database intranet app for schools using the Django framework. I’m trying to get the teacher to update the registered student’s assessment within the Teachers account.

How to verify the Authorization header using OAuth 1.0a or HMAC-SHA1 and Django Rest Framework

Django: Why is password not correctly encrypted after changing to a custom user model?
When I register a user, the password is passed to my backend not correctly. In my admin panel I get the error 'Invalid password format or unknown hash algorithm'.

Rendering Plotly graph onto Django application using data from SQL
I'm trying to integrate a Plotly scatter graph into my Django application following the instructions laid out here: Embedding a Plotly chart in a Django template. The data I want to render on the Plotly graph is from the application's SQL database but I can't figure out how to query the data without dropping values from the dataset. Below is the views.py file: release_dates = list(models.Film.objects.values_list('release_date', flat=True).distinct()) gross = list(models.Film.objects.values_list('gross', flat=True).distinct()) title = list(models.Film.objects.values_list('title', flat=True).distinct()) class Graph(TemplateView): template_name = 'graph.html' def get_context_data(self, **kwargs): context = super(Graph, self).get_context_data(**kwargs) trace1 = go.Scatter(x=release_dates, y=gross, marker={'color': 'red'}, hovertext = title, mode="markers+text", name='1st Trace') data=go.Data([trace1]) layout=go.Layout(title="Films by Gross", xaxis= {'title':'Year'}, yaxis={'title':'Gross'}) figure=go.Figure(data=data,layout=layout) div = opy.plot(figure, auto_open=False, output_type='div') context['graph'] = div return context The problem is that when the Plotly Graph is rendered on the webpage, the data comes out jumbled so that the films' titles don't match their release dates and their gross. I think the problem is that there are missing or "null" values in the database so when I call the list function on the "release_date", "gross" and "title" values_list, the data become misaligned.
