Django Form Based on Variable Attributes

it fixes the issue The answer is "yes". You can construct any Django form or other entity dynamically at runtime rather than as a declarative class. You may find it useful to peruse my self-answered questiion here How to reduce Django class based view boilerplate. It's not about forms, but it is a pretty full exposition of how you get from a Django-style declarative class to a dynamic construction of the same thing.
If you google "Django dynamic form" you will find a lot more form-related stuff. You may find that what you need has already been done (try searching the Django packages web site).
MyDynamicFormClass  = type( 'MyDynamicForm', (forms.Form, ), dict_of_fields)
dict_of_fields = {}

for cat in cats:
    choices = [ ]
    for char in get_characteristics( cat):
        choices.append( (db_value_for_char, user_label_for_char) )

    dict_of_fields[ cat_name ] = forms.ChoiceField( choices, ...)

What is the perferred way to customize the form variable from a class-based Generic View in Django?

I hope this helps you . To answer the part of your question concerning which fields of the model should be available in the form, you could create a custom form with ModelForm. The options fields and exclude define which fields are available in the form:
https://docs.djangoproject.com/en/dev/topics/forms/modelforms/#using-a-subset-of-fields-on-the-form
url(
    r'^orders/create/$',
    CreateView.as_view(
        model = Order,
        template_name = 'doors/orders/create.html',
        form_class = OrderCreateForm,
    ),
    name = 'orders_create'
),

I wish this help you You can dynamically modify your form by using init and self.fields dict. Something like this:
class UploadImageForm(forms.Form):

    def __init__(self, something=None, *args, **kwargs):

        super(UploadImageForm, self).__init__(*args, **kwargs)
        self.fields['stream_id'] = something

To fix this issue You can set the value of the widget.attrs to pass certain other HTML attributes to the form.
>>> from django import forms
>>> name = forms.TextInput(attrs={'size': 10, 'title': 'Your name',})
>>> name.render('name', 'A name')
u'<input title="Your name" type="text" name="name" value="A name" size="10" />'
