Deploy Problems with Ubuntu + Django + Apache2
I'm a beginner to Django and apache2. Here's my server environment: ubuntu 18.04 + Apache/2.4.29 (Ubuntu) + Python 3.6.8 + Django 2.2.6 + MySQL 5.7 I follow the Django document: https://docs.djangoproject.com/en/2.2/howto/deployment/wsgi/modwsgi/ and also some solution from InterNet.

Django application server requirement with ubuntu + apache + mod_wsgi
I need your guidence on setting up my production server for django application. Below are the details of my application . Its a simple website which connects 3 database/applications that is already available in 3 separate VM's. The 3 applications are: 1) MSSQL database(which will provide details of a parent table(model) and 15 or 20 child tables(model). when each record from the parent model is opened it fetches the details of other child tables and display them in the page) 2) Document management system to stream the files(average of 10 files with each documents with 150-200 kb size of each document) related to the records that are fetched with the previous step. 3) Mysql database (which will give few more details related to the parent model from the parent model) Now my new VM which we are going to setup should have a simple RDBMS created with postgreg to hold the basic details of django and the website users along with python and django. The current user base is 5-6 users at a time and may grow to 10 -12. Can some one recommend a capacity planning for the above requirement for DJANGO+ UBUNTU + APACHE + MOD_WSGI( please suggest … -

Django urls.py: best way to not have a page number in the first page of a list view?
Right now I have a list view that displays 10 posts per page: The urls would be something like this: www.example.com/posts/1 (First page with 10 results) www.example.com/posts/2 (Next page with 10 results) and my urls.py looks something like this: path('posts/<int:page>', PostList.as_view(), name='post-list'), I want to be able to have the first page of posts also visible when there is no number, for example: www.example.com/posts (First page with 10 results) The only way that I have been able to solve this is by adding another line in the urls.py that points to the same view and that has the same name. path('posts', PostList.as_view(), name='post-list'), path('posts/<int:page>', PostList.as_view(), name='post-list'), Is this the appropriate way of doing this or is there a better way? Many thanks! -

Django AJAX working but test case failing in POST request
So I have this unit test: def test_delete_product(self): self.api_client.login(username=self.username, password=self.password) path = self.get_url_for_test_against_endpoint('/product/delete/') data = {'id': self.product.id} response = self.api_client.post(path=path, data=json.dumps(data), content_type='application/json') self.assertEqual(response.status_code, 302) self.assertFalse(Product.objects.filter(id=self.product.id).exists()) and this view def post(self, request): pid = request.POST.get('id') get_object_or_404(Product, id=pid).delete() return redirect('product:products') My entry in urls.py is path('product/delete/', product_delete_view, name='product_delete') The AJAX I am using to call this view is: <script> const url = "{% url 'product:product_delete' %}" var id = "{{ product.id }}" var intId = parseInt(id) const data = { id: intId, csrfmiddlewaretoken: '{{ csrf_token }}' , contentType:'application/json'} $('#{{ product.id }}').click(function () { $.post(url, data, function (data, status) { console.log(`${data} and status is ${status}`) location.reload(true) }) }) </script> What works: When I call this view through ajax, everything works fine and the product is deleted. What does NOT work When I run the test, it fails because response.status_code returns 404. While trying to find out what the problem is, I used pdb.set_trace() in view and I found that request.POST.get('id') returns None. If I hard code pid to 1 test case passes which means in the view, it is unable to get id from the request which is weird because it is able to do that same through ajax call. If I do … -

Prevent Redis/Celery scheduled tasks from being processed multiple times - Django on Heroku
I am looking for some advice. I use Celery/Redis Scheduled tasks to check changes via an API request every 10 seconds. If there is a change, a database object will be created and when it did some calculations a boolean named is_called will be set to True, to prevent duplicates. This worked fine locally and for a time also on Heroku, but since an update (nothing in the task code changed) the worker seems busy and uses up to 7 ForkPoolWorkers. For example the ForkPoolWorker-1 will work on the same task as ForkPoolWorker-7, which ignores the is_called = True boolean and gives me duplicate calculations with 1 database object created. What's the best way to serve a task only to 1 ForkPoolWorker at a time? I read the docs and google research, but it's not completely clear what and how to do this. I build in Django on Heroku. -

Django Forms (with crispy forms) - Am I over complicating this? Is there an easier way?

How to access all content from request.session | Django

search results from a Django model method including the results from earlier calls to the same method
