Need help getting this snippet to work in Django 1.2...

[mhulse]

I feel like this should be simple...

I would like to replace this model field:

date = models.DateField(_(u'Year'), unique=True)

...with this snippet:

http://djangosnippets.org/snippets/508/

I have spent the last couple hours banging my head on my keyboard...

During the course of my tests, at one point, I was getting an error that said something like "__init__() got an unexpected keyword argument 'unique'" (I think I was trying to extend IntegerField).

Any tips on how to convert that snippet so I can do:

from app.fields import YearField
...
year = YearField(_(u'Year'), unique=True)
...

Normally I wouldn't ask, but I am ready to give up... At this point, I am just curious to see how it's done for the sake of learning something new.

Thanks so much!

Cheers,
Micky

I think this is not how it works. The snippet is a form field, not a model field. Basically I think you should use an IntegerField (you just want to store a year, right?). Then somehow you need to override the widget or so and make sure that in the admin that form will be used for that IntegerField. This form field basically just makes sure, that people don't enter anything stupid, but what is being saved will just be a normal integer, I guess.

Sorry, don't have enough time to give a better hint.

Best regards,

Martin

Hi Martin! Thanks so much for the help, I really appreciate it. :)

> The snippet is a form field, not a model field.

Well, that would explain things! Lol.

When I read this in the instructions:

"Usage eg: yob = BirthYearField(label="What year were you born?")"

I thought that was a model field.

Thanks for pointing me in the right direction! :)

Have a nice day.

It'll be better to use validators with IntegerField

https://docs.djangoproject.com/en/1.3/ref/models/fields/#validators

https://docs.djangoproject.com/en/1.3/ref/validators/

In this case you can specify allowed year range.

Ooh, great tip! That looks very useful and possibly a little more
simple/straight-forward than using a form field.

Much appreciated.

Have a great day!
