Re: Trouble with Django in production server.

[Jonathan D. Baker]

Instead of hard-coding paths, check out os.path, os.abspath and os.sep (and the 
rest of the os module) for such needs. I usually declare a PROJECT_ROOT var at 
the top of my settings.py using the aforementioned os module, and then hang 
paths (like your db path) off of that instead of building each path 
individually.

Glad you figured it out.

Re: Get memory-use serverside when rendering a view?

[Jonathan D. Baker]

There definitely could already be middleware that accomplishes this (I've never 
looked). Even if you end up writing your own, I think you'll enjoy the process 
of grokking the django request/response cycle and seeing how powerful 
middleware can be.

Good luck with the task, and cheers.

Re: ignore field during form validation

[Jonathan D. Baker]

Hi Sarfraz,

If your form class inherits from ModelForm, you can use a subset of
fields within your form per the following documentation:
https://docs.djangoproject.com/en/dev/topics/forms/modelforms/#using-a-subset-of-fields-on-the-form

If you're not inheriting from ModelForm, then it's a matter of
configuring your model and form fields to allow null/blank. In this
case, seeing your code would help provide more direction.

Hope this helps,
Jonathan
