我尝试创建自定义占位符以在网站上添加管理员可编辑的部分。 Django-cms' documentation对于添加它应该做些什么非常通用。
占位符位于一个名为 contacts 的单独应用中,已添加到 settings.py 文件中
这里是我的代码到目前为止(跳过导入更简洁):
models.py
class ContactsPlaceholder(models.Model):
phone = models.CharField(max_length=100)
email = models.CharField(max_length=100)
address = models.TextField(max_length=700)
# your fields
my_placeholder = PlaceholderField('contacts_contactsplaceholder')
# your methods
def __unicode__(self):
return "Contacts Placeholder"
views.py
def contacts(request):
# Load the the contacts from db
contactsfields = ContactsField.objects.all()
contacts_placeholder = ContactsPlaceholder.objects.all()
context = {"contactsfields" : contactsfields, "contacts_placeholder" : contacts_placeholder}
return render(request, "../templates/contacts.html", context)
def contacts_placeholder_detail(request, id): # is this really useful?
object = get_object_or_404(ContactsPlaceholder, id=id)
return render_to_response('../templates/contacts_placeholder_detail.html', {
'object': object,
}, context_instance=RequestContext(request))
contacts.html
{% extends "base.html" %}
{% load cms_tags %}
{% block content %}
<div>
<h1>Contacts</h1>
{% placeholder "contacts_placeholder" or %}
<p>Placeholder is empty</p>
{% endplaceholder %}
</div>
{% endblock content %}
最后, admin.py
class ContactsPlaceholderAdmin(PlaceholderAdminMixin, admin.ModelAdmin):
# Editable fields
frontend_editable_fields = ("phone", "email", "address")
# Form fields order and sections
fieldsets = [
(None,{"fields" : ["phone", "email", "address"]})
]
admin.site.register(ContactsPlaceholder, ContactsPlaceholderAdmin)
使用此配置,在运行
python manage.py syncdb后,我确实得到了#34;占位符为空&#34;在html响应中,当然占位符不能使用标准前端编辑器进行编辑,这是期望的行为。
转到 127.0.0.1:8000/admin / 我可以看到&#34;联系人占位符&#34;表,但是当我点击它或尝试添加项目时,我会收到以下错误:
OperationalError at /us/admin/contacts/contactsplaceholder/
no such column: contacts_contactsplaceholder.phone
答案 0 :(得分:2)
如果通过app挂钩呈现contacts()
视图,则在模板中使用{% placeholder "contacts_placeholder" %}
将无效。
在通过AppHook连接到CMS的应用中使用占位符时,您必须使用{% static_placeholder "MyPlaceholder" %}
而不是通常的{% Placeholder "MyPlaceholder" %}
如果你有一个应用程序或插件,你已经在其中创建了一个PlaceholderField,那么在你的模板中呈现它,你需要以下标记;
{% render_placeholder instance.placeholderfieldname %}
