【问题描述】：
是否有完整的 sweetpie django 示例站点和设置可供下载？我整天都在努力把头缠在上面。我有以下代码。基本上，我有一个用 ajax 处理的 POST 表单。当我在表单上单击“提交”并运行 ajax 请求时，调用返回“POST http://192.168.1.110:8000/api/private/client_basic_info/ 404 (NOT FOUND)”我认为 URL 配置正确。我可以访问http://192.168.1.110:8000/api/private/client_basic_info/?format=json 就好了。我是否遗漏了一些设置或在我的方法中犯了一些基本错误？我的意图是每个用户可以填写/修改一个且只有一个“客户基本信息”表格/模型。
一个页面：
{% extends "layout-column-100.html" %}
{% load uni_form_tags sekizai_tags %}
{% block title %}Basic Information{% endblock %}
{% block main_content %}
{% addtoblock "js" %}
<script language="JavaScript">
$(document).ready( function() {
$('#client_basic_info_form').submit(function (e) {
form = $(this)
form.find('span.error-message, span.success-message').remove()
form.find('.invalid').removeClass('invalid')
form.find('input[type="submit"]').attr('disabled', 'disabled')
e.preventDefault();
var values = {}
$.each($(this).serializeArray(), function(i, field) {
values[field.name] = field.value;
})
$.ajax({
type: 'POST',
contentType: 'application/json',
data: JSON.stringify(values),
dataType: 'json',
processData: false,
url: '/api/private/client_basic_info/',
success: function(data, status, jqXHR) {
form.find('input[type="submit"]')
.after('<span class="success-message">Saved successfully!</span>')
.removeAttr('disabled')
},
error: function(jqXHR, textStatus, errorThrown) {
console.log(jqXHR)
console.log(textStatus)
console.log(errorThrown)
var errors = JSON.parse(jqXHR.responseText)
for (field in errors) {
var field_error = errors[field][0]
$('#id_' + field).addClass('invalid')
.after('<span class="error-message">'+ field_error +'</span>')
}
form.find('input[type="submit"]').removeAttr('disabled')
}
}) // end $.ajax()
}) // end $('#client_basic_info_form').submit()
}) // end $(document).ready()
</script>
{% endaddtoblock %}
{% uni_form form form.helper %}
{% endblock %}

我将 ClientBasicInfo 的用户字段设为可为空，并且 POST 似乎可以正常工作。我现在想尝试更新条目。那只是将pk附加到ajax url吗？例如 /api/private/client_basic_info/21/?当我提交该表单时，我收到一条 501 NOT IMPLEMENTED 消息。我究竟没有实施什么？我正在继承 ModelResource，它应该根据文档实现所有与 ORM 相关的功能。
【问题讨论】：
-
APPEND_SLASHES 可能有问题？您是否尝试过发帖到192.168.1.110:8000/api/private/client_basic_info（不带斜杠）？只是猜测。
-
嗯，我去掉了 url 的斜线，得到“你通过 POST 调用了这个 URL，但是 URL 没有以斜线结尾，并且你设置了 APPEND_SLASH。”我将 APPEND_SLASH = False 应用于我的设置，现在我收到一条 403 Forbidden 消息（CSRF 验证失败）。我通过使视图 csrf_exempt 克服了这一点。现在我得到一个 501 未实现的错误。我添加了一个自定义水合物功能并通过了它。我尝试提交一个表单来更新对象，但我收到另一个错误。一个又一个的错误，我想我会放弃seatpiepie。
-
我不是 TastyPie 专家，所以只能做出更多猜测。您是否尝试过使用不同的身份验证和授权后端？尝试分别使用tastepie 的
Authorization和Authentication类进行授权和身份验证。他们应该非常宽容。只是为了检查是否是问题所在。 -
我刚刚将授权和身份验证都更改为完全允许的，但我仍然得到 501 not implemented 错误。
