Card() 得到了一个意外的关键字参数“初始”

Question

I'm putting together a CRUD interface without using the admin app, still pretty new to Python and Django, but when I go to create an entry, it throws out the error in my title.

here's the target page:

<form method="post">
  {% csrf_token %}
  Card Name:<br>
  <input type="text" name="name"><br>
  Mana Cost:<br>
  <input type="text" name="mana_cost"><br>
  Supertype:<br>
  <input type="text" name="supertype"><br>
  Keyword 1:<br>
  <input type="text" name="keyword_1"><br>
  Keyword 2:<br>
  <input type="text" name="keyword_2"><br>
  Keyword 3:<br>
  <input type="text" name="keyword_3"><br>
  Rules Text:<br>
  <input type="text" name="rules_text"><br>
  Power & Toughness:<br>
  <input type="text" name="power_toughness"><br>
  <input type="submit" value="Add Card"><br>
{% endblock %}

my views.py:

from task99_app import forms
from django.views.generic import ListView
from django.views.generic import DetailView
from django.views.generic.edit import CreateView
from django.views.generic.edit import UpdateView
from django.views.generic.edit import DeleteView
from .models import Card
# Create your views here.

def home(request):
    return render(request, 'home.html')

class CardList(ListView):
    model = Card

class CardCreate(CreateView):
    form_class = Card

class CardDetail(DetailView):
    model = Card

class CardUpdate(UpdateView):
    model = Card

class CardDelete(DeleteView):
    model = Card

my forms.py:

from django import forms


class CardForm(forms.ModelForm):
    name = forms.CharField(max_length=80)
    mana_cost = forms.CharField(max_length=12)
    supertype = forms.CharField(max_length=30)
    keyword_1 = forms.CharField(max_length=20)
    keyword_2 = forms.CharField(max_length=20)
    keyword_3 = forms.CharField(max_length=20)
    rules_text = forms.CharField(max_length=500)
    power_toughness = forms.CharField(max_length=10)

and my models.py:

from django import forms

class CardForm(forms.ModelForm):
    name = forms.CharField(max_length=80)
    mana_cost = forms.CharField(max_length=12)
    supertype = forms.CharField(max_length=30)
    keyword_1 = forms.CharField(max_length=20)
    keyword_2 = forms.CharField(max_length=20)
    keyword_3 = forms.CharField(max_length=20)
    rules_text = forms.CharField(max_length=500)
    power_toughness = forms.CharField(max_length=10)

I've seen a few instances of this happening to others, but I don't understand their code well enough to understand how to fix mine, but I feel so close.

EDIT: urls.py:

from django.contrib import admin
from django.urls import path
from django.conf.urls import url
from task99_app import views

urlpatterns = [
    url('admin/', admin.site.urls),
    url(r'form/$', views.CardCreate.as_view(), name='card_create'),
    url(r'^$', views.home, name='home'),
    url(r'card_list/$', views.CardList.as_view(), name='card_list'),
    url(r'card/<int:pk>', views.CardDetail.as_view(), name='card_details'),
    url(r'delete/<int:pk>', views.CardDelete.as_view(), name='card_delete'),
    url(r'update/<int:pk>', views.CardUpdate.as_view(), name='card_update'),
    ]

Answer 1

In your CardCreate view, you have used the model as form_class , not your Form :

class CardCreate(CreateView):
    
    form_class = 

EDIT 1 : Note that in your UpdateView , you forgot to set a form_class . That is not per se necessary, but then you need to specify fields [Django-doc] . You can however use the same form_class :

class CardUpdate(UpdateView):
    model = Card
    form_class = 

Furthermore you need to specify the model in your CardForm :

class CardForm(forms.ModelForm):
    name = forms.CharField(max_length=80)
    mana_cost = forms.CharField(max_length=12)
    supertype = forms.CharField(max_length=30)
    keyword_1 = forms.CharField(max_length=20)
    keyword_2 = forms.CharField(max_length=20)
    keyword_3 = forms.CharField(max_length=20)
    rules_text = forms.CharField(max_length=500)
    power_toughness = forms.CharField(max_length=10)

    class Meta:
        
        fields = '__all__'

EDIT 2 : Note that in your urls.py you use path syntax in url(..) s, you should use path(..) [Django-doc] instead:

urlpatterns = [
    'admin/', admin.site.urls,
    'form/', views.CardCreate.as_view(), name='card_create',
    '', views.home, name='home',
    'card_list/', views.CardList.as_view(), name='card_list',
    'card/<int:pk>', views.CardDetail.as_view(), name='card_details',
    'delete/<int:pk>', views.CardDelete.as_view(), name='card_delete',
    'update/<int:pk>', views.CardUpdate.as_view(), name='card_update',
]
