How to debug in Django code

0 votes
I usually just use the debug info Django gives when enabled. When things do end up as I thought it would, I break the code flow a lot with a syntax error, and look at the variables at that point in the flow to figure out, where the code does something other than what I wanted.

But can this be improved? Are there some good tools or better ways to debug your Django code?

Hello @kartik,

There are a bunch of ways to do it, but the most straightforward is to simply use the Python debugger. Just add following line in to a Django view function:

import pdb; pdb.set_trace()

or

breakpoint()  #from Python3.7

If you try to load that page in your browser, the browser will hang and you get a prompt to carry on debugging on actual executing code.

However there are other options (I am not recommending them):

  • * return HttpResponse({variable to inspect})
    
    * print {variable to inspect}
    
    * raise Exception({variable to inspect})

Hope this is helpfull!!

Thank you!!
