django - 单元格颜色 Django-Tables2

Question

问题:我在哪里编辑我的 Django 代码以根据业务逻辑更改单个单元格的背景颜色？

在我的 views.py 中，我有捕获“pts”列最大值的逻辑:

def show_teams(request):
reg = Teamoffense.objects.filter(~Q(rk='RK'))
pts = Teamoffense.objects.filter(~Q(pts='PTS')).values('pts')
seq = [item['pts'] for item in pts]
maxseq = max(seq)

table = SimpleTable(reg)
table_to_report = RequestConfig(request).configure(table)
if table_to_report:
    return create_report_http_response(table_to_report, request)
return render(request, 'index.html', {
    'table': table,
    'reg': reg,
    'maxseq': maxseq,
})

如何在该列中呈现具有最大值的任何单元格 a bgcolor = 'green'？我目前有一个简单的表格，显示如下:

class SimpleTable(TableReport):

class Meta:
    model = Teamoffense
    exclude = ("column1","column2")
    exclude_from_report = ("column1","column2")
    attrs = {'class': 'paleblue'}

经过更多研究调查 Django-Tables2 API Docs我发现 Table.render_foo methods是我的情况所需要的。这会更改列的呈现方式。确保设置 column.attrs 而不是 self.attrs，因为根据我的经验，这是我能够设置单个单元格样式的方式。

#tables.py
import django_tables2 as tables
from .models import MyTable
from MyApp import views


class SimpleTable(tables.Table):


    def __init__(self, *args, **kwargs):
        super(SimpleTable, self).__init__(*args, **kwargs)
        self.maxpts = views.maxpts

    #render_foo example method
    def render_pts(self, value, column):
        if value == self.maxpts:
            column.attrs = {'td': {'bgcolor': 'lightgreen'}}
        else:
            column.attrs = {'td': {}}
        return value


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