How to add data to modal body dynamically while a function in views.py is running in Django
I have a BS Modal as below: <div id="myModal" class="modal fade" role="dialog"> <div class="modal-dialog modal-lg"> <div class="modal-content"> <div class="modal-header"> <h4 class="modal-title" align="center">Add Some value</h4> </div> <div class="modal-body"> <form action = "{% url 'add_function' %}" method = "POST" role="form"> {% csrf_token %} <table> <tbody> <tr> <td> TaskId / Topology File </td> <td><input required name="value" type="text"><td> </tr> </tbody> </table> <br> <div class="modal-footer"> <button type="button" class="btn btn-danger" data-dismiss="modal">Close</button> <input type="submit" value="Save" class="btn btn-success"> </div> </form> </div> </div> </div> </div> After the form is submitted, a function runs in views.py def add_function(request): sometask1 sometask2 sometask3 sometask4 return render(request,'some.html') These task takes some time to get finished.

Django and accessing POST data from forms.Form
For some reason, this form appears to only be able to POST the 'email' parameter. I would have expected that calling request.POST in the views.py file down below would have given me access to 4 variables, but I can only access 'email'.

Django setUp class only execute once
I am currently following a django tutorial (https://youtu.be/UqSJCVePEWU?t=8655) and he uses the setUp function to make test cases. I did the same thing as him and I get an error that the username is not UNIQUE self.c = Client() User.objects.create(username='admin') Category.objects.create(name='django', slug='django') self.data1 = Product.objects.create(category_id=1, title='django beginners', created_by_id=1, slug='django-beginners', price='19.99', image='django') def test_url_allowed_hosts(self): response = self.c.get('/') self.assertEqual(response.status_code, 200) def test_product_detail_url(self): response = self.c.get(reverse('store:product_detail', args=['django-beginners'])) self.assertEqual(response.status_code, 200) so, after some hours I found that setUp is executed for every test (which does not create any problem in the tutorial) and I changed my function to @classmethod def setUpClass(self): which solves the problem, but now I don't know if I messed something up and the tutorial should work, or something in django has changed since then. Any help is appreciated and if any files or something is needed I'll provide them. Thank you in advance -

M1 Mac - GDAL Wrong Architecture Error [Django]
I'm trying to get a django project up and running, which depends on GDAL library. I'm working on a M1 based mac. Following the instructions on official Django docs, I've installed the necessary packages via brew $ brew install postgresql $ brew install postgis $ brew install gdal $ brew install libgeoip gdalinfo --version runs fine and shows the version as 3.3.1 gdal-config --libs returns this path: -L/opt/homebrew/Cellar/gdal/3.3.1_2/lib -lgdal a symlink is also placed on the homebrew's lib directory, which is in my path. When I try to run django, it complains that it cannot find the GDAL package. When I try to specify the path to the GDAL library using GDAL_LIBRARY_PATH, I get this error: OSError: dlopen(/opt/homebrew/Cellar/gdal/3.3.1_2/lib/libgdal.dylib, 6): no suitable image found.

How to determine in javascript when a dict of images created in django has loaded
I am using django and javascript. When a page is first loaded I load a dict of images (around 85 in all) and I don't want the javascript to attempt to display the images until I am sure that all of the images are loaded js $(document).ready(function () { $.ajax( { type: "GET", url: "/common/load-common-data/", cache: false, success: function (context) { images = context.images; setTimeout(() => { displayImages(images) }, 750); } } ); } This is unsatisfactory because the 750 ms delay is arbitrary and might not be sufficient in specific cases I have seen attempts to solve this, but they rely on loading the images individually whereas for various reasons I need to select the images in my view and upload them as a dict. -
