【问题描述】：
我正在尝试构建一个包含多个图表的仪表板类型网站。我将 Django 与 FusionCharts 和 Postregsql 数据库后端一起使用。我可以得到一张图表来呈现，但我根本无法让第二张图表出现。我认为这可能是我的views.py 中我创建函数的方式。非常感谢任何帮助。
代码如下：
views.py
from django.shortcuts import render
from django.http import HttpResponse
# Include the `fusioncharts.py` file that contains functions to embed the charts.
from .fusioncharts import FusionCharts
from .models import *
# The `chart` function is defined to load data from a `Country` Model.
# This data will be converted to JSON and the chart will be rendered.
def chart(request):
# Chart data is passed to the `dataSource` parameter, as dict, in the form of key-value pairs.
dataSource = {}
dataSource['chart'] = {
"caption": "Final Sale Price by Customer",
"showValues": "0",
"theme": "fint"
}
dataSource['data'] = []
for key in Customer.objects.all():
data = {}
data['label'] = key.customername
data['value'] = key.Final_Price
dataSource['data'].append(data)
column2D = FusionCharts("column2D", "ex1", "600", "350", "chart-1", "json", dataSource)
return render(request, 'dashboard.html', {'output': column2D.render()})
def chart2(request):
# Chart data is passed to the `dataSource` parameter, as dict, in the form of key-value pairs.
dataSource2 = {}
dataSource2['chart'] = {
"caption": "Final Sale Price by Plant",
"showValues": "0",
"theme": "fint"
}
dataSource2['data'] = []
for key in Customer.objects.all():
data = {}
data['label'] = key.customername
data['value'] = key.Final_Price
dataSource2['data'].append(data)
column2D = FusionCharts("column2D", "ex1", "600", "350", "chart-2", "json", dataSource2)
return render(request, 'dashboard.html', {'output2': column2D.render()})
dashboard.html
{% extends "index.html" %}
{% load static %}
{% block title %}{{title}}{% endblock title %}
{% block sidenav %}
{% for page in page_list %}
<li>
<a href="{{page.permalink}}">{{page.title}}</a>
</li>
{% endfor %}
{% endblock sidenav %}
{% block content %}
{% autoescape off %}
{{ content }}
{% endautoescape %}
<p>
<table>
<tr>
<th>Customer</th>
<th>Plant</th>
</tr>
<tr>
<td><div id="chart-1">{{ output|safe }}</div></td>
<td><div id="chart-2">{{ output|safe }}</div><h1>test</h1></td>
</tr>
</table>
Page last Update: {{last_updated|date:'D d F Y' }}
</p>
{% endblock content %}

class Plant(models.Model):
site = models.CharField(max_length=250)
Final_Price = models.CharField(max_length=50)
def __unicode__(self):
return u'%s %s' % (self.site, self.Final_Price)
