  • Best way to write an image to a Django HttpResponse()

    - by k-g-f
    I need to serve images securely to validated users only (i.e. they can't be served as static files). I currently have the following Python view in my Django project, but it seems inefficient. Any ideas for a better way? def secureImage(request,imagePath): response = HttpResponse(mimetype="image/png") img = Image.open(imagePath) img.save(response,'png') return response (Image is imported from PIL.)

  • PHP's form bracket trick is to Django's ___?

    - by Matt
    In PHP you can create form elements with names like: category[1] category[2] or even category[junk] category[test] When the form is posted, category is automatically turned into a nice dictionary like: category[1] => "the input value", category[2] => "the other input value" Is there a way to do that in Django? request.POST.getlist isn't quite right, because it simply returns a list, not a dictionary. I need the keys too.

  • Setting custom SQL in django admin

    - by eugene y
    I'm trying to set up a proxy model in django admin. It will represent a subset of the original model. The code from models.py: class MyManager(models.Manager): def get_query_set(self): return super(MyManager, self).get_query_set().filter(some_column='value') class MyModel(OrigModel): objects = MyManager() class Meta: proxy = True Now instead of filter() I need to use a complex SELECT statement with JOINS. What's the proper way to inject it wholly to the custom manager?

  • How to span multile tables in Django

    - by ipartola
    The Django documentation gives en example like so: b = Blog.objects.get(id=1) b.entry_set.all() Which from what I understand results in 2 queries. What if I wanted to get the blog, the blog entries and all the comments associated with that entry in a number of queries that does not depend on the number of entries?

  • Django for web2py developers

    - by carrier
    Now that I've gotten relatively familiar with web2py, I'd like to give Django a go. What are the main differences? What would be the most efficient way to get started taking into account web2py knowledge? (It must help to have some python application framework knowledge,no?)
