Using model instance in admin form with script

[Robert Steckroth]

class RssFeedPageForm(forms.ModelForm):

    class Meta:

        model = RssFeedPage

    def clean_link(self):

        self.instance.save()

        page_model_instance=self.instance, rss_item=RssFeedItem, feed_url=self.data['link'])

   UpdateFeeds().parse_feed(page_model_instance=self.instance, rss_item=RssFeedItem, feed_url=self.data['link'])

Opps, sorry. I was actually trying to ask how one would get a hold of the current model in this admin form, but the Esc key for some reason sent the message.

The above function works, but the instance is not a model instance which can be saved. How would I go about getting the current RssFeedPage model which pertains to the form instance?

This works great on the cli --> from Django_project.update_rss_feeds import *; m = get_models(); rss_page = m[1]; rss_item=m[2]; UpdateFeeds().parse_feed(page_model_instance=rss_page.objects.get(pk=1), rss_item=rss_item, feed_url="http://rss.nytimes.com/services/xml/rss/nyt/HomePage.xml")

..because I pass in a usable model to -> parse_feed(page_model_instance=model)

Note: this script will be open-sourced shortly. I will post the repo when it is ready :)

So that does not work. Is there a builtin method that will allow me to call the script before the form is rendered in save_model?

    form = RssFeedPageForm # <-- how can this be loaded with UpdateFeeds ValidationErrors?

    def save_model(self, request, obj, form, change):

        # UpdateFeeds().parse_feed will raise VailidationError

        UpdateFeeds().parse_feed(update_feed_data=True, update_item_data=True, page_model_instance=obj, rss_item=RssFeedItem, feed_url=form.data['link'])
