Question

当我访问更新页面时，它不会使用现有的条目数据填充字段（就在那里，我在视图的某些部分放置的打印语句显示它可以访问<存在），我不确定为什么它没有填充。

这是我的观点：

@login_required
def sites_update_view(request, place_id=None):

    if place_id:
        place = get_object_or_404(SiteMeta, pk=place_id)
    else:
        return redirect('sites-index')

    if request.POST:
        form = SitesAddForm(request.POST, instance=place)
        if form.is_valid():
            form.save()
            return redirect('sites-index')
    else:
        form = SitesAddForm(instance=place)

    return render(request, 'sites-update.html', {
        'form': form,
        'site': place,
        'place_id': place_id
    })

我的模板：

{% extends "newbase.html" %}
{% load url from future %}
{% load floppyforms %}
{% load staticfiles %}
{% block title %} - Update Site {% endblock %}
{% block content %}
<div class="row">
<div class="col-sm-6 col-md-6">

                    {{ form.site_category }}
                <span class="help-block">What category should the site be in?</span>
