Different initial data for each form in a Django formset

Is it possible to prepopulate a formset with different data for each row? I'd like to put some information in hidden fields from a previous view.

According to the docs you can only set initial across the board.

I had this problem and I made a new widget:

from django.forms.widgets import Select
from django.utils.safestring import mark_safe
class PrepolutatedSelect(Select):
    def render(self, name, value, attrs=None, choices=()):
        if value is None: value = ''
        if value == '':
            value = int(name.split('-')[1])+1
        final_attrs = self.build_attrs(attrs, name=name)
        output = [u'<select%s>' % flatatt(final_attrs)]
        options = self.render_options(choices, [value])
        if options:
            output.append(options)
        output.append('</select>')
        return mark_safe(u'\n'.join(output))

Maybe this will work for you too.

formset = BookFormset(request.GET or None,initial=[{'formfield1': x.modelfield_name1,'formfield2':x.modelfield_name2} for x in model])

formfield1,formfield2 are the names of the formfields.

modelfield_name1,modelfield_name2 are the modal field names.

model is name of your modal class in models.py file.

BookFormset is the form or formset name which is defined in your forms.py file
