Lack DateTime formats in some languages

[Pablo Martín]

Lack DateTime formats in some languages.

For example in english:

DATETIME_INPUT_FORMATS = (
    '%Y-%m-%d %H:%M:%S',     # '2006-10-25 14:30:59'
    '%Y-%m-%d %H:%M',        # '2006-10-25 14:30'
    '%Y-%m-%d',              # '2006-10-25'
    '%m/%d/%Y %H:%M:%S',     # '10/25/2006 14:30:59'
    '%m/%d/%Y %H:%M',        # '10/25/2006 14:30'
    '%m/%d/%Y',              # '10/25/2006'
    '%m/%d/%y %H:%M:%S',     # '10/25/06 14:30:59'
    '%m/%d/%y %H:%M',        # '10/25/06 14:30'
    '%m/%d/%y',              # '10/25/06'
)

But in spanish, I think that it lacks this format '%d/%m/%y' :

DATETIME_INPUT_FORMATS = (
    '%d/%m/%Y %H:%M:%S',
    '%d/%m/%Y %H:%M',
    '%d/%m/%y %H:%M:%S',
    '%d/%m/%y %H:%M',
)

Indeed, there is an inconsistency here.

pmartin, are ca and es_* the only languages where datetime input formats do not include the date input formats?

More generally, wouldn't it be a good idea to consider any valid date input format and a valid datetime_input_format, and remove a lot of copy-paste from the formats.py files?

[Pablo Martín]

It is possible that the formats could be grouped. But this is not the scope of the ticket. It's a little change to fix a bug.

Also it would also be difficult to ​overwrite

[Marc Garcia]

I assume that the English locale approach of allowing date formats to datetime fields is the right one. Then, I think it makes more sense what aaugustin says, of getting rid of the date formats in the datetime settings, and change the code to allow this.

My only concern is that if there is a side case, where order can matter. Formats are checked in order, and testing first the datetime ones, and then the date ones, won't let a locale to specify the exact order.
