How to use AJAX spinner in django(prefer to use some library) while waiting until file is processed in backend
The Form I want that after I click the submit button a spinner/progressbar(preferred) should pop up on the screen while the uploaded file is being processed in the backend. A csv file will be processed and based on number of rows processed the width of the progressbar should change. I don't know how that signal to change the width dynamically can be tuned.It would be better if the progressbar hides the form for the duration the file is being processed. Once the file is processed then the /success/ template will be loaded where I would show some stats of the files like number of rows failed to process. I saw this package but 'm too noob to use it. I know javascript and so please don't hesisate to talk about that if required. https://pypi.org/project/django-lazy-tags/ Thanks, class EmailView(FormView): template_name = 'Email/index.html' form_class = forms.EmailForm success_url = '/success/' def form_valid(self, form): # form.send_email() # return super().form_valid(form) print(form) index.html {% extends 'Base/index.html' %} {% load static %} {% load crispy_forms_tags %} {% load bootstrap4 %} {% load lazy_tags %} {% bootstrap_css %} {% block main %} <link rel="stylesheet" href="{% static 'Email/index.css' %}"> {% crispy form %} {% endblock main %} form.py class EmailForm(forms.Form): … -

how do I make an element not work as href in an entire href card
So I have this card that works as an entire link but inside that, I have an icon under a span tag and I don't want it to work as the card's link rather just act like an icon, Ik I can solve this if I don't make the entire card href but then I'd have to manually turn all the required elements present inside the card into href which I feel like isn't efficient and neat. So any suggestions on how do I go from here? {% for m in mlist %} <div class="card"> <a href="http://www.google.com/search?q={{m.Name}}" target="_blank"> <div class="top"> <div class="year">{{m.Year}}</div> <span class="span-bookmark"><i class="material-icons bookmark" id="bookmark-style">bookmark</i></span> </div> <div class="middle"> <div class="img-container"><img src="{{ m.Image.url }}"></div> </div> <div class="bottom"> <div class="title">{{m.Name}}</div> <div class="target_id">{{m.targetid}}</div> </div> </a> </div> {% endfor %} -

Upload File to Django Admin, Process it, and Deliver to Template
I would like to upload a file object in the admin, run a process on this to convert it to html, and deliver the result to a template. I cannot figure out how to access the file object in order to run the handler, but the file itself is .json (jupyter notebook). Here is a basic model: #blog/models.py class FileUploader(models.Model): title = models.CharField(max_length = 200) notebook = models.FileField(upload_to='./notebooks/') In my views I have a notebook converter function: #blog/views.py def upload_file(request): notebook_html = converter(request.FILES['notebook']) return render(request, 'test.html', context={'html': notebook_html}) then, in my urls I have: #blog/urls.py urlpatterns = [ path('', views.upload_file, name = 'notebook_page') ] When I go to view the page, I get a MultiValueDictKeyError at /blog/ 'notebook' error. I'm not sure how to access the notebook file itself to run the conversion process on, not sure where in the MultiValueDict object this is or how it works. Big idea is to upload the file, convert it to html, inject in template. -

Trying to Use Gulp to Run Sass
It used to be you couldn't trust answers over five years old. Now it seems to be just down to months. I'm trying to set up Gulp to watch and compile my sass file in my Django project I followed the app doc to install gulp. The sample task worked. Every answer I saw to run sass was different. This version seemed to run the best: 'use strict'; // function defaultTask(cb) { // // place code for your default task here // cb(); // } // // exports.default = defaultTask var gulp = require('gulp'); var sass = require('gulp-sass'); sass.compiler = require('node-sass'); gulp.task('watch', function () { gulp.watch('./base/static/base/css/stylesheets/main.scss', gulp.series('sass')); }); gulp.task('default', gulp.series('sass', 'watch')); The commented out code was from the install and it worked. The error I get is "Task never defined: sass" gulp version 4.0.2 on MacOS. I also can't see where it plans to put the output css file. The correct location is one directory out from the input. I'm giving the path from where I'm running gulp, which is the root of the project. When I run sass manually, I use this command: /usr/local/bin/sass main.scss:../main.css I run it in the stylesheets directory. I have to specify the version because … -
Order Objects using an associated model and timedelta
I have a puzzle on my hands. As an exercise, I am trying to write a queryset that helps me visualize which of my professional contacts I should prioritize corresponding with. To this end I have a couple of models: class Person(models.Model): name = models.CharField(max_length=256) email = models.EmailField(blank=True, null=True) target_contact_interval = models.IntegerField(default=45) class ContactInstance(models.Model): person = models.ForeignKey(Person, on_delete=models.CASCADE, related_name='contacts') date = models.DateField() notes = models.TextField(blank=True, null=True) The column target_contact_interval on the Person model generally specifies the maximum amount of days that should pass before I reach out to this person again. A ContactInstance reflects a single point of contact with a Person. A Person can have a reverse relationship with many ContactInstance objects. So, the first Person in the queryset should own the greatest difference between the date of the most recent ContactInstance related to it and its own target_contact_interval So my dream function would look something like: Person.objects.order_by(contact__latest__date__day - timedelta(days=F(target_contact_interval)) but of course that won't work for a variety of reasons. I'm sure someone could write up some raw PostgreSQL for this, but I am really curious to know if there is a way to accomplish it using only the Django ORM. Here are the pieces I've found so … -
Django DRF adds double quotes around response even though it shouldn't
I'm trying to get some data from another API and return it on my local setup. It's a very simple script that calls the API and should just return the exact identical response to me. I'm using Django DRF btw. @api_view(['GET',]) def onlinenodes(request): """ Show Online nodes """ if request.method == 'GET': response = requests.get("https://stats.golem.network/v1/nodes") return Response(response.text) My issue is that, when I return my response.text and query my own API it returns the data but with double quotes around the JSON object, which I don't want. I literally just want to return the data received from the external API that has no double quotes around the JSON object. Issue visualized from my returned response: "[ { ... } ]" But I just want to return the following as i'm getting from the external API: [ { ... } ] If I try to print(response.text) it doesn't contain any double quotes either. It simply just happens in my response. What do I do to remove them?
