Question

我正在尝试在django项目中创建数据可视化仪表板，我正在使用highchart js来实现这一点。我的问题是甚至在遵循文档之后，我的数据甚至没有显示为简单的折线图。我肯定错过了什么，请帮助。

我的模特

class Company(models.Model):
    name = models.CharField(max_length=100)
    phone = models.CharField(max_length=50)
    email = models.EmailField(max_length=75)
    city = models.ForeignKey(City)
    sector = models.ForeignKey(Sector)
    description = models.TextField()

    def __unicode__(self):
        return self.name

class Feedback(models.Model):
    PENDING,RESOLVED = range(2)
    FEEDBACK_STATUS = (
        (PENDING,'Pending'),
        (RESOLVED, 'Resolved'),
        )
    title = models.CharField(max_length=100)
    feed_back = models.TextField(verbose_name='feed back')
    date_posted = models.DateTimeField(verbose_name='date posted',auto_now_add=True)
    customer = models.ForeignKey(Customer)
    company = models.ForeignKey(Company)
   status = models.PositiveSmallIntegerField(null = True ,choices=FEEDBACK_STATUS, blank = True)
    # status = models.BooleanField(default=False)
    objects = FeedbackManager()

    def __unicode__(self):
        return self.title

views.py

def chart_data(request):
    """
    this model holds the data visualization datasets
    """
    company = Company.objects.get(pk=1)
    feedbacks = Feedback.objects.filter(company=company)
    feeds = feedbacks.count()
    return render_to_response('cfback/dashboard.html',RequestContext(request, {'company':company,
                                                                               'feeds':feeds}))

在模板方面，我有以下代码 base.html文件 https://codeshare.io/5w9wDD

和dashboard.html是 https://codeshare.io/5zlKvk

你会在dashboard.html上注明我正在测试来自highcharts的演示图表，并从我的模型中调用变量来测试是否有任何显示，其余的是来自演示应用程序的值。

xAxis: {
        categories: [{{company}},{{company}},{{company}},{{company}},{{company}}],
        title: {
            text: null
        }

帮助弄清楚失踪的是什么，过去2天我一直在这。我几乎放弃了高等教育并尝试了其他的东西。感谢
