"Conditionally disabling actions" documentation needs updating

Description (last modified by aaugustin)

The docs in question are:

The suggestion is to use del actions['delete_selected'], which worked fine in Django 1.2. However, because of changes made to django.contrib.admin.options.get_actions, in the case that IS_POPUP_VAR == True, this del statement will result in an exception. Need a try/except or something.

I think it would be a bit cleaner and read better using the conditional test: if actions.has_key('delete_selected'). What do you think?

Please don't use has_key. It's idiomatic to do:

if 'delete_selected' in actions:
    # whatever

Agreed, that's even better. Thanks for correcting me :p

I'm sure we could write a whole book on the respective merits of

mydict.pop('mykey', None)    # that's unpythonic.


if 'mykey' in mydict:
    del mydict['mykey']      # we're writing the dict and key names twice!


    del mydict['mykey']
except KeyError:
    pass                     # four lines for this?

Anyway, here's an updated patch...

Now, back to triaging the unreviewed tickets queue.

Thanks for the updated patch. IMO, writing the key twice is the lesser evil in this case ;)

FTR, I've mentioned that because Alex specifically removed the use of has_key in r14392 to speed up Django a bit. I think it was regarding using Django on PyPy.
