I have an issue with co-ordinate transform from within Django, to do with SRID 29902 (Irish National Grid).

/usr/share/proj/epsg contains the following line:

<29902> +proj=tmerc +lat_0=53.5 +lon_0=-8 +k=1.000035 +x_0=200000 +y_0=250000 +a=6377340.189 +b=6356034.447938534 +units=m +no_defs +datum=ire65 <>

And this works from the command line:

$ cs2cs -f "%.15f" +init=epsg:29902 +to +init=epsg:4326
326905 369342

I'm upgrading an old Django 1.1 project to a clean Django 1.5 installation. The Django upgrade itself has gone very well; {% url %} changes, settings, some class-based generic views, some core patches replaced with a custom User model, others done with nicer middleware, and so on, hooray.

What I didn't expect to stop working, but has, is a model creation form that lets someone add a related object at the same time. In the code, this is done using a MultiValueField subclass:

class AutoCompleteMultiValueField(forms.MultiValueField):
    def __init__(self, model, column, *args, **kwargs):
        self.model = model
        self.column = column
        super(AutoCompleteMultiValueField, self).__init__(*args, **kwargs)
