问题 I am trying to build a import form for a CSV file into the admin interface for a given model. the view can be reached from the change_list of the model, but it throws a template syntax error.

django: guidelines for speeding up template rendering performance

阅读更多关于 django: guidelines for speeding up template rendering performance

问题 How would I go about speeding up Django template rendering? My template takes about 1-2 seconds or so to render, after the view function fully computes whatever it needs to. I've already attempted to perform all database access in the view, such that the template only hits RAM and not the DB engine.

问题 My model is returning a Decimal(1234567.50), I can't seem to display the Decimal with a thousands separator. Does Django have a way to do this? Do I need to create my own template filter?

You'll have to convert to float/string first. 回答2: One easy way is to import locale and do the formatting in your view function. Even easier to read this: http://docs.djangoproject

问题 Suppose my template has in it something like {% block subject %}my subject{% endblock %} and I load this template with tmpl = loader.get_template('mytemplate.html') , how can I extract "my subject"? 回答1: Camilo's solution doesn't work when your template extends a base.

问题 I ran into an interesting "oversight" in the Django {% cycle %} template tag. This has been listed as a bug, but I'm wondering if there is a workaround for it? {% for r1 in range_0_2 %} {% for r2 in range_0_3 %} {{ r1 }}-{{ r2 }}-{{ cycle 'even' 'odd' }} {% endfor %} {% endfor %} This yields: 0-0-even 0-1-odd 0-2-even 1-0-odd 1-1-even 1-2-odd It should yield: 0-0-even 0-1-odd 0-2-even 1-0-even 1-1-odd 1-2-even 回答1: I have noticed the same problem in my templates.
