私はちょうどDjangoの学習を始めました。このプロジェクトでは、 "Tango with Django"のチュートリアルブックに従います。ボタンが表示されているようですが、フォームの入力フィールドに問題があります。Djangoフォームフィールドが表示されません
は、ここに私のコードです:
models.py
[...]
class Idea(models.Model):
keyword = models.ForeignKey(Keyword)
word = models.CharField(max_length=120)
count = models.IntegerField(default=1)
def __str__(self):
return self.word
forms.py
[...]
class Meta:
model = Keyword
fields = ('name',)
class IdeaForm(forms.ModelForm):
word = forms.CharField(max_length=120)
count = forms.IntegerField(widget=forms.HiddenInput(), initial=1)
class Meta:
model = Idea
fields = ('word',)
exclude = ('keyword',)
views.py
[...]
def keyword_detail(request, keyword_name_slug):
form = IdeaForm()
context_dict = {}
try:
keyword = Keyword.objects.get(slug=keyword_name_slug)
ideas = Idea.objects.filter(keyword=keyword)
context_dict['keyword'] = keyword
context_dict['ideas'] = ideas
except Keyword.DoesNotExist:
context_dict['keyword'] = None
context_dict['ideas'] = None
if request.method == 'POST':
form = IdeaForm(request.POST)
if form.is_valid():
idea = form.save(commit=False)
idea.keyword = keyword
idea.count = 1
idea.save()
return keyword_detail(request, keyword_name_slug)
else:
print(form.errors)
context_dict['form'] = form
return render(request, 'openminds/keyword.html', context_dict)
keyword.html
[...]
<h3>Add a new Idea</h3>
<div>
<form id="idea_form" method="post" action="">{% csrf_token %}
{% for hidden in forms.hidden_fields %}
{{ hidden }}
{% endfor %}
{% for field in forms.visible_fields %}
{{ field.errors }}
{{ field }}
{% endfor %}
<input type="submit" name="submit" value="Add Idea" />
</form>
</div>
