示例1: __init__
# 需要导入模块: from django import forms [as 别名]
# 或者: from django.forms import MultiValueField [as 别名]
def __init__(self, field_items, skip_check=False, *args, **kwargs):
self.field_dict = OrderedDict(field_items)
self.skip_check = skip_check
# Make sure no subfield is named 'SKIP_CHECK_NAME'. If
# skip_check is True this field will clash with the addtional
# subfield added by the DictCharField constructor. We perform
# this check even if skip_check=False because having a field named
# 'skip_check' that isn't used to actually skip the checks would be
# very confusing.
if SKIP_CHECK_NAME in self.field_dict:
raise RuntimeError(
"'%s' is a reserved name "
"(it can't be used to name a subfield)." % SKIP_CHECK_NAME
)
# if skip_check: add a BooleanField to the list of fields, this will
# be used to skip the validation of the fields and accept arbitrary
# data.
if skip_check:
self.field_dict[SKIP_CHECK_NAME] = forms.BooleanField(
required=False
)
self.names = [name for name in self.field_dict]
# Create the DictCharWidget with init values from the list of fields.
self.fields = list(self.field_dict.values())

[field.widget for field in self.fields],
self.names,
[field.initial for field in self.fields],
[field.label for field in self.fields],
skip_check=skip_check,
)
# Upcall to Field and not MultiValueField to avoid setting all the
# subfields' 'required' attributes to False.
