django-tables2无法对某些字段进行排序

我有一个如下定义的Django模型:

class DummyModel(models.Model):
    name = models.CharField(max_length=100, name='Name')
    description = models.CharField(name='Description', max_length=150)
    time_points = models.PositiveIntegerField(name="Time Points")
    more_text = models.CharField(max_length=100, name="More Text")

    class Meta:
        db_table = "dummy"

我想稍后做一些自定义,所以我也有一个表类:

class DummyTable(tables.Table):
    class Meta:
        model = DummyModel
        attrs = {'class': 'paleblue'}

我有一个相应的观点如下:

@login_required(login_url="login/")
def review(request):
    table = DummyTable(DummyModel.objects.all())
    RequestConfig(request).configure(table)
    return render(request, 'review.html', {'reviews': table})

最后,我使用:

将其渲染到我的模板中
{% block content %}
    {% load static %}
    {% load render_table from django_tables2 %}
    <div class="function-container">
        {% render_table reviews %}
    </div>
{% endblock %}

现在这个渲染很好但是当我尝试对time Points列进行排序时(通过点击列标题),它会出现错误:

Invalid order_by arguments: [u'Time Points']
Request Method: GET
Request URL:    http://127.0.0.1:8000/review/?sort=Time+Points
Django Version: 1.10.5
Exception Type: FieldError
Exception Value:    
Invalid order_by arguments: [u'Time Points']

但是,如果我将浏览器指向http://127.0.0.1:8000/review/?sort=time_points,则可行。因此,不知道如何传递正确的字段名称。我尝试更改name并将verbose_namne字段添加为:

time_points = models.PositiveIntegerField(name="time_points", verbose_name="Time Points")

但是,这会在no such column: dummy.time_points

中返回

答案 0 :(得分:0)

我想出了一种方法,即覆盖我的table类中的列。所以,现在我的模型看起来像:

class DummyModel(models.Model):
    name = models.CharField(max_length=100)
    description = models.CharField(max_length=150)
    time_points = models.PositiveIntegerField()
    more_text = models.CharField(max_length=100)

    class Meta:
        db_table = "dummy"

在我的自定义table课程中,我有:

class DummyTable(tables.Table):
    #Override here to change the column header text 
    time_points = tables.Column(verbose_name='Time Points')
    more_text = tables.Column(verbose_name='More Text')

    class Meta:
        model = DummyModel
        attrs = {'class': 'paleblue'}

现在排序按预期工作。
