Question

我是python，django和javascript的新手。在我的localhost网站上显示任何东西都是一个突破，但现在我试图让它显示为数据表，它只是填充为我认为的原始json数据。我猜这可能是导致这种情况的模板中的东西，但我很新手所以非常感谢任何帮助。

Models.py

from django.db import models

class pitcher（models.Model）：

id = models.IntegerField(primary_key=True)
player_name = models.CharField('pitcher name', max_length=255, default='null')
pitch_type = models.CharField(max_length=255, default='null')
game_date = models.DateField(null=True, blank=True)
release_speed = models.FloatField()
pfx_x = models.FloatField()
pfx_z = models.FloatField()
spin_rate = models.FloatField()
estimated_ba_using_speedangle = models.FloatField()
estimated_woba_using_speedangle = models.FloatField()
babip_value = models.FloatField()
Usage = models.FloatField()

urls.py

from django.conf.urls import url
from analyzer import views
from analyzer.views import pitcherlist
import json

urlpatterns = [
    url(r'^$', pitcherlist.as_view(), name='pitcherlist_json'),
]

views.py

from django.shortcuts import render
from .models import pitcher
from django_datatables_view.base_datatable_view import BaseDatatableView
import json
from django.http.response import HttpResponse

class pitcherlist(BaseDatatableView):
    model = pitcher
    columns = ['player_name', 'game_date','pitch_type', 'pfx_x']
    max_display_length = 500

模板

<body>

<div class="container">

        <div class="col-sm-12 col-md-12">
            <div class="well">
                <table id="pitcherlist" class="display responsive" width="100%">
                    <thead>
                        <tr>
                            <th width="5%">player_name</th>
                            <th width="5%">game_date</th>
                            <th width="5%">pitch_type</th>
                            <th width="5%">pfx_x</th>
                            <th width="5%"></th>
                        </tr>
                    </thead>
                </table>
            </div>
        </div>
    </div>

<script type="text/javascript" charset="utf-8">

$(document).ready(function() {
    var oTable: $('#pitcherlist').dataTable({
        "processing": true,
        "serverSide": true,
        "ajaxSource": {% url 'pitcherlist_json' %}
    });




</script>
</body>
</html>

这是输出：

{“draw”：0，“recordsTotal”：171，“recordsFiltered”：171，“data”： [[“Hector Neris”，“2017-07-31”，“FF”， - 0.6053]，[“Hector Neris”， “2017-07-31”，“FS”，-1.1989]，[“Hector Neris”，“2017-07-31”，“FF”， -0.7938]，[“Hector Neris”，“2017-07-31”，“FF”， - 0.7876]，[“Hector Neris”，“2017-07-31”，“FF”， - 0.8419]，[“ Hector Neris“，”2017-07-31“， “FF”， - 0.9699]，[“Hector Neris”，“2017-07-31”，“FF”， - 0.8357]， [“Hector Neris”，“2017-07-31”，“FS”， - 0.8772]，[“Hector Neris”， “2017-07-31”，“FF”， - 0.6558]，[“Hector Neris”，“2017-07-31”，“FF”， -0.6579]]，“结果”：“ok”}

检查一下。 How to build up a HTML table with a simple for loop in Jinja2?您将必须执行以下操作：

<table>
  {% for x in pitcherlist%}
  <tr>
     <th width="5%">player_name</th>
     <th width="5%">game_date</th>
     <th width="5%">pitch_type</th>
     <th width="5%">pfx_x</th>
  </tr>
    <td>{{ x.player_name}}</td>
    <td>{{ x.game_date}}</td>
    <td>{{ x.pitch_type}}</td>
    <td>{{ x.pfx_x}}</td>
  </tr>

  {% endfor %}
</table>

Django Datatables Views不显示数据表，只显示json
