如何使编辑功能具有预先填充的内容

Question

当用户单击"编辑"按钮时，我正试图将现有内容作为文本区域的初始值(即用户在添加页面时之前键入的内容应在用户想要编辑页面时显示(。

当我点击编辑时，以前写的内容往往会转到url中的标题页。你能帮我看看为什么吗？

VIEWS.PY

class AddPageForm(forms.Form):
title = forms.CharField(max_length=20)
content = forms.CharField(widget=forms.Textarea(
attrs={
"class": "form-control",
})
)
class EditPageForm(forms.Form):
content = forms.CharField(widget=forms.Textarea(
attrs={
"class": "form-control",
})
)

def edit_page(request, title):
entry = util.get_entry(title)
if request.method == "GET":
form = EditPageForm(request.POST, initial={
"content": entry
})

else:
form = EditPageForm(request.POST)

if form.is_valid():
title = form.cleaned_data['title']
content = form.cleaned_data['content']
util.save_entry(title, content)
return redirect('encyclopedia:entrypage', title)
return render(request, 'encyclopedia/editpage.html', {'form': form})

编辑页面

{% block body %}
<h1>Edit {{ title }}</h1>
<form action="" method="post">
{% csrf_token %}
{% form %}
<input type="submit" value="Submit" class="btn btn-secondary">
</form>

条目页面

{% block body %}
{{ content|safe }}
<a href="{% url 'encyclopedia:editpage' title=title %}" class="btn btn-primary">Edit</a>
{% endblock %}

URLS.PY

app_name = "encyclopedia"
urlpatterns = [
path("", views.index, name="index"),
path("wiki/<str:title>", views.entry_page, name="entrypage"),
path("search", views.search, name="search"),
path("add_page", views.add_page, name="addpage"),
path("edit_page/<str:title>", views.edit_page, name="editpage")
]

utils中的get entry函数有什么？

这样做：-

entry = Model.objects.all().last()
form = EditPageForm(request.POST, initial={"content": entry.content}
