如何使编辑功能具有以前的预填充内容

Question

我试图使现有内容成为文本区域的初始值（即用户在添加该页面之前输入的内容应该在用户想要编辑页面时显示。）当用户点击编辑按钮时.

当我点击编辑时，之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？

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>

进入页面

{% block body %}
        {{ content|safe }}

        <a href="{% url 'encyclopedia:editpage' title=title %}" class="btn btn-primary">Edit</a>

{% endblock %}

utils 中的 get 入口函数是什么？

做这样的事情：-

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