Is it possible to format a django_filters filter form with django-crispy-forms? I've been trying to do that, but django_filters.FilterSet
doesn't seem to accept the crispy forms formats (from DeviceFilter class). It doesn't give an error either.The only thing that seems to be able to give a format is {{ filter.form|crispy }}
but I want to be able to do it in python with FormHelper()
.
filters.py
from crispy_forms.helper import FormHelper
from crispy_forms.layout import Layout, Submit, Row, Column
import django_filters
class DeviceFilter(django_filters.FilterSet):
device_type = django_filters.ModelChoiceFilter(lookup_expr='exact', field_name='device_type__pk',
queryset=None)
device_group = django_filters.ModelChoiceFilter(lookup_expr='exact, field_name='device_group__pk',
queryset=None)
def __init__(self, *args, **kwargs):
super().__init__(*args, **kwargs)
self.filters['device_type'].queryset = DeviceType.objects.filter(owner=self.request.user)
self.filters['device_group'].queryset = DeviceGroup.objects.filter(owner=self.request.user)
self.helper = FormHelper()
self.helper.layout = Layout(
Row(
Column('device_type', css_class='form-group col-md-6 mb-0'),
Column('device_group', css_class='form-group col-md-4 mb-0'),
css_class='form-row'
),
Submit('submit', 'filter')
)
class Meta:
model = Device
fields = {}
template
<!-- filter -->
{% if filter %}
<form method="get">
{{ filter.form|crispy }}
</form>
{% endif %}
UPDATE
I share my final solution. This renders this:
class DeviceForm(forms.ModelForm):
class Meta:
model = Device
fields = [
'device_id',
'device_type',
'device_group',
]
def __init__(self, *args, **kwargs):
super().__init__(*args, **kwargs)
self.helper = FormHelper()
self.helper.layout = Layout(
Row(
Column('device_created', css_class='form-group col-12'),
css_class='form-row'
),
Row(
Column('device_id', css_class='form-group col-12'),
css_class='form-row'
),
Row(
Column('device_type', css_class='form-group col-6 mb-0'),
Column('device_group', css_class='form-group col-6 mb-0'),
css_class='form-row'
),
)
class DeviceFilter(django_filters.FilterSet):
device_created = django_filters.DateTimeFromToRangeFilter(label='', widget=MyRangeWidget(
{
'class': 'datetimepicker form-control',
'placeholder': 'From'
}, {
'class': 'datetimepicker form-control',
'placeholder': 'To'
}
))
device_id = django_filters.CharFilter(label='', lookup_expr='icontains', widget=TextInput(attrs={
'placeholder': 'Enter Device Id'
}))
device_group = django_filters.ModelChoiceFilter(label='', lookup_expr='exact',
field_name='device_group__pk',
queryset=None, empty_label=('Select Group'))
device_type = django_filters.ModelChoiceFilter(label='', lookup_expr='exact',
field_name='device_type__pk',
queryset=None, empty_label=('Select Type'))
class Meta:
form = DeviceForm
def __init__(self, *args, **kwargs):
super().__init__(*args, **kwargs)
self.filters['device_type'].queryset = DeviceType.objects.filter(owner=self.request.user)
self.filters['device_group'].queryset = DeviceGroup.objects.filter(owner=self.request.user)
Try setting the helper to the form
def __init__(self, *args, **kwargs):
super().__init__(*args, **kwargs)
# Your code
self.form.helper = FormHelper()
# Your code
Or try setting the form in the meta class
class DeviceFilter(django_filters.FilterSet):
# Your code
class Meta:
form = YourCustomFormClass
