Django ModelForm； 用户，此字段为必填项

Question

I am having some issues with a (model)form consisting of just a single button. When I try to submit the form this message is displayed:

user This field is required.

The ModelForm looks like this:

from django.forms import ModelForm
from .models import HulpOproep


class HulpOproepForm(ModelForm):
    class Meta:
        model = HulpOproep
        fields = ['user', ]

The Model looks like this:

class HulpOproep(models.Model):
    user = models.ForeignKey(User)

    time = models.DateTimeField(auto_now_add=True, verbose_name='Tijd')

    def __str__(self):
        return '%s %s' % (self.user.username, str(self.time))

    def username(self):
        return self.user.username

    def first_name(self):
        return self.user.first_name

    def last_name(self):
        return self.user.last_name

    class Meta:
        verbose_name = 'Hulp Oproep'
        verbose_name_plural = 'Hulp Oproepen'

The View looks like this:

def verzend_oproep(request):
    if request.method == 'POST':
        form = HulpOproepForm(request.POST)
        if form.is_valid():
            oproep = form.save(commit=False)
            oproep.user = request.user
            oproep.save()
            return redirect('portal/index/')
    else:
        form = HulpOproepForm()
    return render(request, 'portal/verzend_oproep.html', {'form': form})

The Template:

{% extends "base.html" %}
{% block head %}
    <title>Zorggroep | Hulp Oproep</title>
{% endblock %}

{% block body%}
    <h1>Verstuur Hulpoproep</h1>
    <form method="POST" class="post-form">{% csrf_token %}
        {{ form.as_P }}
        {{ form.errors }}
        <button type="submit" class="save btn btn-default">Verstuur</button>
    </form>
{% endblock %}

The 'user' in the HulpOproep model is a ForeignKey and should be the currently logged in user's User object. I tried to specify this using the line:

oproep.user = request.user

So what should happen is: Get the current user's 'User' object and use it as the 'HulpOproepForm.user'. This way the 'HulpOproepForm.user' is the 'HulpOproep.user' and a Foreign Key.

I have followed multiple tutorials and have searched around, but I cannot find a solution. I'm sorry if the answer is logical, but I have been using Django for only 5 days and have 1.5 months of programming experience under my belt.

Thank you!

Thanks PatNowak and Radek!

I did not know the form was waiting for user input instead of code input. I managed to fix it by adding exclude to the ModelForm.

class HulpOproepForm(ModelForm):
    class Meta:
        model = HulpOproep
        exclude = ['user', 'time']
