Django动态模型设计

Question

I have a table that contains a dynamic number of entries, each entry contains data (like id, name, date) and also 3 radio buttons.

    class Entry(models.Model):
        id = ...
        name = ...
        data = ...
        selected_option = ...

I want to save all of the entries in the DB when the user submits the form.
I was wondering what would be the best way to design the model for this.

I am not sure how your data looks like. It's not bad to store huge amount of data or structure your data. Let's say there are fixed number of options from which user will select the radio button right, you can store those options as choices in your db.

class Entry(models.Model):
    entry_id = ...
    name = ...
    date = ...

class SelectedOption(models.Model):
    class Options:
        OPTION_1 = 'O1'
        OPTION_2 = 'O2'
        Choices = (
           (OPTION_1, 'Option 1'),
           (OPTION_2, 'Option 2'),
        )

    option = CharField(choices=Options.Choices, max_length=2)
    entry = ForeignKey(Entry)

I think this way you won't have repetition of data. And your data will be more structured if you want to perform some analysis.
