title: How to use the parameter queryset of model formset in ModelForm?
body: <pre><code># this is my model
  class Creator(models.Model):
      name = models.CharField(max_length=50)
  
  
  class Article(models.Model):
      title = models.CharField(max_length=688, blank=True)
      creator = models.ForeignKey(Creator, on_delete=models.CASCADE)
  
  
  class ArticleCoAuthor(models.Model):
      article = models.ForeignKey(Article, on_delete=models.CASCADE)
      co_author = models.CharField(max_length=190)
  
  # code
  ArticleFormset = modelformset_factory(Article, form=forms.ArticleForm, extra=1, can_delete=True)
  article_formset = ArticleFormset(
      prefix=&quot;article&quot;, queryset=creator.article_set.prefetch_related(&quot;articlecoauthor_set&quot;).all()
  )
  
  # this is my form
  class ArticleForm(forms.ModelForm):
  ......
  </code></pre>
  <p>I want to express all the data of the ArticleCoAuthor referenced when representing a row of Articles.</p>
  <p>How can I convey the &quot;co_author&quot; value, which is the result of &quot;querieset&quot; in &quot;article_formset&quot;, and use it in &quot;ArticleForm&quot;?</p>
