Hi i have found an issue while developing my webapp

So i tried to render my template called marketingup.html and it showed me an issue i've never seen

My model:

class MarketingUp(models.Model):
    user = models.ForeignKey(User, on_delete=models.CASCADE)
    name = models.CharField(max_length=200)
    description = models.TextField(max_length=200, null=True)
    def __str__(self):
        return f'{self.name}'

My form:

class MarketingUp(forms.ModelForm):
    
    class Meta:
        model = MarketingUp
        fields = ['user','name','description']

My view:

@login_required
def add_upsell(request):
    context={}
    if request.method == 'POST':
        form = MarketingUp(request.POST)
        if form.is_valid():
            form.save()
            messages.success(request, f'Offer created successfully')
            return redirect('marketing')
    context['form'] = MarketingUp
    return render(request, 'users/marketingup.html', context)

My template (HTML):

{% extends "homepage/base.html" %} {% load crispy_forms_tags %}
<!---->
{% block body %}

<body>
    {% endblock %}
    <!---->
    {% block content %}
    <!---->

    <div class="content-section">
        <form method="POST" enctype="multipart/form-data">
            {% csrf_token %}
            <fieldset class="form-group">
                <legend align="center" class="border-bottom mb-3"><strong>Add New UpSell Offer</strong></legend>
                {{form|crispy}}


            </fieldset>

            <div class="form_group">
                <button align="center" class="btn btn-outline-info" type="submit">Create</button>
            </div>

        </form>
    </div>
    <!---->
    {% endblock %}

@ Brunoseixas at high level looks like your FORM is not rendering properly on GET request. I think it because its not initialized properly. Can you try this out,

@login_required
def add_upsell(request):
    context={}
    if request.method == 'POST':
        form = MarketingUp(request.POST)
        if form.is_valid():
            form.save()
            messages.success(request, f'Offer created successfully')
            return redirect('marketing')
    #scott 
    form = MarketingUp()
    context['form'] = form
    return render(request, 'users/marketingup.html', context)
