Django-tables2 change yesno parameter for all BooleanColumn
I have a table.py where I would like to change the icons for True and False values for each BooleanColumn. I know it can be changed with the yesno BooleanColumn parameter, but I don't know how to override the default for all BooleanColumns. Here is the tables.py code (aacsb, amba, equis, mba, bsc, msc, and doubedegree - BooleanFields):
from django_tables2 import Column, Table
from manager.models import Partner
class PartnerTable(Table):
country_name = Column(accessor='country.name', verbose_name='Country')
region_name = Column(accessor='country.region.name', verbose_name='Region')
class Meta:
model = Partner
fields = ('name',
'country_name',
'region_name',
'website',
'aacsb',
'amba',
'equis',
'mba',
'bsc',
'msc',
'doubledegree',
)

1) So you can just override the yesno
default "✔, ✘" (it's easy str
):
some_name = BooleanColumn(yesno='1,2')
or remove text:
some_name = BooleanColumn(yesno=',')
2) Using css
, you can specify custom images (don't forget to install yesno=','
):
span.true {
background: url(../img/true.gif) top center no-repeat;
}
span.false {
background: url(../img/false.gif) top center no-repeat;
}
3) Specify additional attributes span
(but do not specify class
!):
some_name = BooleanColumn(attrs={'span': {'style': 'color:blue'}})
4) If for some reason you want to change the behavior of the default class settings ( true
or false
) - you must override BooleanColumn
its methodrender
from django.utils.html import escape
from django.utils.safestring import mark_safe
from django_tables2.utils import AttributeDict
class CustomBooleanColumn(BooleanColumn):
def render(self, value):
value = bool(value)
text = self.yesno[int(not value)]
html = '<span %s>%s</span>'
class_name = 'some_class_false'
if value:
class_name = 'some_class_true'
attrs = {'class': 'class_name'}
attrs.update(self.attrs.get('span', {}))
return mark_safe(html % (AttributeDict(attrs).as_html(), escape(text)))
And override the field
some_name = CustomBooleanColumn(yesno=',')

Here is the complete code now, thanks to madzohan's answer. Please note that I used django-bootstrap3 so that I can use the bootstrap icons:
from django_tables2 import BooleanColumn, Column, Table
from django.utils.safestring import mark_safe
from django_tables2.utils import AttributeDict
from manager.models import Partner
class BootstrapBooleanColumn(BooleanColumn):
def __init__(self, null=False, **kwargs):
if null:
kwargs["empty_values"] = ()
super(BooleanColumn, self).__init__(**kwargs)
def render(self, value):
value = bool(value)
html = "<span %s></span>"
class_name = "glyphicon glyphicon-remove"
if value:
class_name = "glyphicon glyphicon-ok"
attrs = {'class': class_name}
attrs.update(self.attrs.get('span', {}))
return mark_safe(html % (AttributeDict(attrs).as_html()))
class PartnerTable(Table):
country_name = Column(accessor='country.name', verbose_name='Country')
region_name = Column(accessor='country.region.name', verbose_name='Region')
aacsb = BootstrapBooleanColumn()
amba = BootstrapBooleanColumn()
equis = BootstrapBooleanColumn()
mba = BootstrapBooleanColumn()
bsc = BootstrapBooleanColumn()
msc = BootstrapBooleanColumn()
doubledegree = BootstrapBooleanColumn()
class Meta:
model = Partner
fields = ('name',
'country_name',
'region_name',
'website',
'aacsb',
'amba',
'equis',
'mba',
'bsc',
'msc',
'doubledegree',
)
