Styling forms and django form values

I'm trying to style a form with CSS. First of all I haven't seen a complete example, other than on the official documentation, so I would appreciate any blog entries, or articles.

Now on my form, a typical Charfield gets translated on html like this:

<input type="text" name="artists" id="id_artists" />

If my form contains errors on some field, the previous Charfield remembers the value and goes:

<input type="text" name="artists" value="Pink Floyd" id="id_artists"  />

How can I get this value (value="Pink Floyd") in django forms? Say my field is {{form.artists}}, I can use {{form.artists}} as the field, {{form.artists.label}} as label, {{form.artists.errors}} and {{form.artists.help_text}}, but how about this value?

Thanks in advance!

You can also add additional validation to the form class to do something with the form data. From djangobook.com:

from django import forms

class ContactForm(forms.Form):
    subject = forms.CharField(max_length=100)
    email = forms.EmailField(required=False)
    message = forms.CharField(widget=forms.Textarea)

    def clean_message(self):
        message = self.cleaned_data['message']
        num_words = len(message.split())
        if num_words < 4:
            raise forms.ValidationError("Not enough words!")
        return message

Inside of the clean_message method you can access a given field using the self.cleaned_data dictionary. This dictionary is available for any form that is validated.

Be sure to return the field, in this case message, or else None is returned.

You can get the current value of the field from the data property:

{{ form.artists.data }}

I can't see the Django documentation mentioning this, but it works...

Create the input field specifically, rather than relying on django to auto-create it.

Something like:

<input type="text" name="artists" id="id_artists" value="{{form.artists.title}}" />

should work
