Re: First models.py needs tuning

"An iterable (e.g., a list or tuple) consisting itself of iterables of exactly two items"

I don't think that constructing choices as a "iterableof 1 item iterables" will work.

Think of each item in the choices iterables as a key-value pair, where the first item is the key (literally is the value that is saved on the DB field), and the value is the "display value".

It wouldn't be the case to use the field choices?

Guilherme,

  Now that I know Field.choices exists it will certainly do the job.

  I read the example as translating a quoted string in two steps to a
two-character, uppercase abbreviation. Would the following one-step list of
choices be correct?

    industry_choices (
        ('Agriculture'),
        ('Business, other'),
        ('Chemicals'),
        ('Energy'),
        ('Law'),
        ('Manufacturing'),
        ('Mining'),
        ('Municipalities'),
        ('Ports/Marine Services'),
        ('Transportation'),
        )
    industry=models.CharField(max_length=24, choices=industry_choices, default='Agriculture')

Thanks,

Rich
