form submit

I just can't seem to find the answer to what I think is a simple question, how do you actually do form submit in django unicorn?

suppose I have a form:

<div class="row">
  <div class="col-3 p2">
    <form class="flex flex-column gap-1 card" unicorn:submit.prevent="search_form_submit">
      <input type="text" placeholder="Keyword" />
      <input type="text" placeholder="Source" />
      <div class="flex justify-content-end">
        <input type="submit" value="Search" />
      </div>
    </form>
  </div>
  <div class="col-9">.col-8</div>
</div>

and the view:

from django_unicorn.components import UnicornView


class NewsView(UnicornView):
    name = "News"

    def __init__(self, *args, **kwargs):
        super().__init__(**kwargs)  # calling super is required
        self.name = kwargs.get("name", "News")

    def search_form_submit(self, params="wasa"):
        print(params)

how do you populate the form parameters? It seems the only way to populate the form data is to do model binding one by one for each input? But what I want is all at once when the user submits the form, is this possible?

answering my own question for future reference, use .defer. Bind the model as usual but add a defer modifier, then on submit (an action) it will "flush" all the changes in the back end, then in your submit callback, you have access to the data
