Python Django管理添加表单ajax调用

因此，我以前在Django/Ajax/Jquery方面取得过成功，但我想知道是否可以在管理控制台中实现这一点。当用户转到“添加新”表单时，我希望他们填写邮政编码，并基于该邮政编码，根据数据库中与该邮政编码对应的值，在下一个字段中过滤可用选项

我正在尝试寻找管理视图，该视图为该表单处理帖子，但我对django比较陌生，很难找到它。也许我想得太多了，有更简单的解决办法吗

创建一个视图，在给定zipcode的情况下，该视图包含可用选项（python）

用于具有邮政编码字段（模板）的型号

向zipcode或事件添加一个侦听器，该侦听器使用响应过滤下一个字段（javascript）

url.py

from django.conf.urls import url

app_name = 'your_app'
urlpatterns = [
    url(r'^query/page/(?P<otherModelSlug>[a-zA-Z0-9]+)/?', PageYouQueryFrom.as_view(), name='query_page'),
    …
    # yourWebsite.com/your_app/util/kittens
    url(r'^util/(?P<fieldValue>[a-zA-Z0-9]+)/?', GetDataUtilitly.as_view(), name='get_data_util'),
]

第\u页您希望\u至\u ajax.html

{% extends "base.html" %}

{% block script-inline %}  
  $(document).ready( function () {
    $("#place_to_query").change(function() {
      var queryURL = "/your_app/util/" + $(this).val();
      queryBox = $(this)
      $.get({
        url: queryURL,
        contentType: "application/x-www-form-urlencoded",
      })
        .done(function( data ) {
          html = $( data ).text()
          queryBox.parent().after(html)
        });
    });
  });
{% endblock script-inline %}

{% block content %}
  {{ otherModel }} <!-- or it could be a specific  field -->
  <input id="place_to_query"></input>
  <!-- The ajax will go here afterwards-->
{% endblock content %}

数据查询视图-GetDataUtilitly.py

from django.views.generic import TemplateView
import requests
from pyquery import PyQuery

# this is a Class Based View, but you can use a function based one too
class GetDataUtilitly(TemplateView):
    template_name = 'path/to/data_template.html'
    def get_context_data(self, **kwargs):
        field_value = self.kwargs['fieldValue']
            page = requests.get('https://www.page.com?searchField=' + field_value)
            pq = PyQuery(page.content)
            # Get the (html) portion of what you want
            result_html = pq('div.c-table__row').html()
            return {'result_html': result_html}

，我应该在哪里创建视图？我可以在管理控制台中为特定页面编写自己的视图吗？url（r'^/admin/denate/pickupschedule/add/'，“path.to.view？”）。那会弄糟什么吗？你把风景放在哪里都不重要。就我个人而言，我会把它放在保存zipcode模型的应用程序中，所以它看起来更像/zipcodes/suggest/或类似的东西

# this is a Class Based View, but you can use a function based one too
class PageYouQueryFrom(TemplateView):
    template_name = 'path/to/page_you_want_to_ajax.html'

    def get_context_data(self, **kwargs):
        context_data = super(PageYouQueryFrom, self).get_context_data(**kwargs)
        context_data['otherModel'] = get_object_or_404(OtherModel, slug=self.kwargs['otherModelSlug'])
        return context_data

from django.views.generic import TemplateView
import requests
from pyquery import PyQuery

# this is a Class Based View, but you can use a function based one too
class GetDataUtilitly(TemplateView):
    template_name = 'path/to/data_template.html'
    def get_context_data(self, **kwargs):
        field_value = self.kwargs['fieldValue']
            page = requests.get('https://www.page.com?searchField=' + field_value)
            pq = PyQuery(page.content)
            # Get the (html) portion of what you want
            result_html = pq('div.c-table__row').html()
            return {'result_html': result_html}
