Mes champs de formulaire ne viennent plus sur la page de mise à jour?

Question

J'ai un modèle 'Partenaire' avec une relation un-à-plusieurs 'Produit'. Quand j'ai ajouté le formset 'Product' j'ai cassé quelque chose à faire avec les relations - le html apparaît toujours par exemple <h3>Products</h3>, et le bouton de soumission reste mais il n'y a plus aucune des boîtes de forme. On dirait que le formulaire est en train d'être chargé mais que quelque chose n'est peut-être plus passé. Toute aide serait grandement appréciée. Voici mon code ci-dessous.

mon forms.py

<div class="container"> 
    <div class='col-sm-6'> 
    <h1>Preview</h1> 
    <hr/> 
     <div class='content-preview'> 
      <h3 id='preview-name'></h3> 
      <p id='preview-mission'></p> 
      <p id='preview-vision'></p> 
      <p id='preview-website-link'></p> 
      <p id='preview-fb-link'></p> 
      <p id='preview-twitter-link'></p> 
      <p id='preview-ig-link'></p> 
     </div> 
    </div> 
    <div class='col-sm-6'> 
     <h1>Form</h1> 
     <hr/> 
     <form method='POST' action='' enctype='multipart/form-data'>{% csrf_token %} 
      {{ partnerForm|crispy }} 
      {{ formset.management_form }} 
      <br> 
      <h3>Products</h3> 
      {% for form in formset %} 
       {{ form|crispy }} 
      {% endfor %} 
      <input type='submit' class='btn btn-default' value='Create Partner' /> 
     </form> 
    </div> 
</div> 

mon form.html

class PartnerForm(forms.ModelForm): 
    mission = forms.CharField(widget=PagedownWidget(show_preview=False)) 
    vision = forms.CharField(widget=PagedownWidget(show_preview=False)) 
    # publish = forms.DateField(widget=forms.SelectDateWidget) 
    class Meta: 
     model = Partner 
     fields = [ 
      "name", 
      "logo", 
      "banner_image", 
      "mission", 
      "vision",

      "store_link", 
      "fb_link", 
      "twitter_link", 
      "ig_link", 
     ]

    image = forms.ImageField(label='Image') 
    class Meta: 
     model = Product 
     fields = [ 
      "name", 
      "link", 
      "description", 
      "price", 
      "image",

S'il vous plaît laissez-moi savoir s'il y a quelque chose que je peux fournir.

Vos vues partner_create et partner_update affichent toutes les deux le modèle partner_form.html.

Cependant, vous n'incluez pas partnerForm ou formset dans le contexte de la vue partner_update. Au lieu de cela, vous incluez form, que vous n'utilisez nulle part dans le modèle.
