Django automatically performing the collectstatic command
In my project, I have a main static folder and a sub folder named static. When I make changes in my sub folder named static (which I specified in COLLECTSTATIC_DIRS within the settings file), I save the file and run the collectstatic command. This successfully saves the changes, however is really inefficient as I am constantly changing css and Javascript files inside my project, which I store as static files. I browsed the web, and came across a solution named whitenoise, which is a pip package. But this package only works for a short period of time, and after a few times of closing and opening my project folder, it completely stopped working. Does anybody have another solution to deal with this problem? Thank you. -

Django rest framework ordering - set the location of None values
Using Django Rest Framework 'ordering_fields' for allowing sorting by all the model fields. I've added a new field that allows sorting by, but the requirement is that when sorting ASC - the None values will be first, and when sorting DESC - they will be last. The default behavior seems to be the opposite. Is there a quick way to tell the view where I want to put the None values results? Django version is 2.1.5. Django rest Framework version is 3.7.7 This is part of the model - class Item(models.Model): PRIORITIES = ( ('1', 'Low'), ('2', 'Normal'), ('3', 'High'), ) identifier = models.IntegerField(default=-1) title = models.CharField(max_length=1000) priority = models.CharField(max_length=50, choices=PRIORITIES, null=True, blank=True) Part of the view: class ItemViewSet(viewsets.ModelViewSet): ordering_fields = tuple(serializer_class.Meta.fields) -

Adding padding to span element when an error message occurs in CSS
In my project, I have a form where users can signup. If an error occurs, I pass it through from my backend(Django) to my frontend. Here in the HTMl, I do an If statement to see if the error has been passed and if so, I want to display it below the field that caused the error. I successfully display the error below the form field the error came from. I display the error inside a span element. The only problem is that I want to add some space above and below the span element itself. I attempt this, but no space at all is added.

Instead, the way is "user -> website (a Django server running on the jump server) -> (database hosts). My task is to build a web query server on our Django website to let our users do some query like Robo3T do. I have already done a "high school student" version like this: 1. Django get the query, check it. 2. Django server runs "mongo shell with --eval + query" with python subprocess to query mongodb. 3. Django return the data as HttpResponse to users. However this method has so many limits. I wandered is there any way to hold the "mongo shell session" on the Django server. So the process become the follows: 1. A user send a query to Django. The query is just a string, and the query can return many data, so the "it" (cursor) has to be used to return more following data. 2. Django open a mongo shell session and query with the string, and send back the first batch of data to …
