我的应用有问题。 在将Django升级到最新版本 - 1.11.4之后,我的三个测试都出现了同样的错误。
AssertionError: False is not true : The formset 'formset' in context 0 does not contain the non-form error 'Musi być podana co najmniej jedna stawka' (actual errors: ['Proszę wysłać 1 lub więcej formularzy.'])
我知道错误是波兰语,但实际情况是一个,它与Django 1.9和Django 1.10一起使用,但它不适用于Django 1.11。
有人可以告诉我Django 1.11中有什么变化吗? 我已经阅读了很多有关它的内容,我几乎尝试了所有内容,但旧版本无效。
也许这个formset没有看到我的错误消息,升级后我必须以另一种方式出错?
class BaseTaxRateInlineFormSet(UniqueFieldsFormSetMixin,
NotEmptyInlineFormSetMixin,
BaseInlineFormSet):
_unique_fields = ('valid_from',)
msg_at_least_one_required = __('Musi być podana co najmniej jedna stawka')
def __init__(self, *args, **kwargs):
super().__init__(*args, **kwargs)
self.queryset = self.queryset.order_by('valid_from')
超类:
class NotEmptyInlineFormSetMixin(object):
"""
Prevents from deleting last not empty row (when other are empty)
"""
msg_at_least_one_required = __(
'Co najmniej jeden wiersz musi być wypełniony'
)
code_at_least_one_required = 'at_least_one_required'
def _form_is_empty(self, form):
return not len(list(filter(None, form.cleaned_data.values())))
def clean(self):
super().clean()
if any(self.errors):
return
forms_to_delete = 0
forms_empty = 0
for form in self.forms:
if self._should_delete_form(form):
forms_to_delete += 1
elif self._form_is_empty(form):
forms_empty += 1
if forms_to_delete + forms_empty == self.total_form_count():
raise ValidationError(
self.msg_at_least_one_required,
code=self.code_at_least_one_required
)
class UniqueFieldsFormSetMixin(object):
"""
Checks if fields (_unique_fields) have unique values in all forms
"""
_unique_fields = []
msg_field_not_unique = __('Wartość nie może się powtarzać')
code_field_not_unique = 'field_not_unique'
def __init__(self, *args, **kwargs):
super().__init__(*args, **kwargs)
if 'unique_fields' in kwargs:
self._unique_fields = kwargs.pop('unique_fields', [])
def clean(self):
super().clean()
if self._unique_fields:
values = {field: set() for field in self._unique_fields}
for form in self.forms:
for field in self._unique_fields:
val = form.cleaned_data.get(field)
if val:
if val in values[field]:
form.add_error(
field,
ValidationError(
self.msg_field_not_unique,
code=self.code_field_not_unique
)
)
values[field].add(val)
并测试:
def test_update_removing_last_row(self):
data = {
# One row for existing rates and one empty.
self.FORMSET_PREFIX + '-TOTAL_FORMS': 2,
self.FORMSET_PREFIX + '-INITIAL_FORMS': 1,
self.FORMSET_PREFIX + '-MAX_NUM_FORMS': 100
}
# First row exists
data = self._load_formset_data(
data, dict(
self.rate_data_1, DELETE='on',
**{'id': self.rate_pk_1, self.related_field: self.instance_pk}
), name=self.instance_name
)
self.client.force_login(self.superuser)
response = self.client.post(self.url_update, data=data)
# Can't remove last row
self.assertEqual(response.status_code, 200)
self.assertFormsetError(
response, 'formset', None, None,
self.base_formset_class.msg_at_least_one_required
)
答案 0 :(得分:0)
问题在于两行Django formset。
if not form.has_changed() and i >= self.initial_form_count():
empty_forms_count += 1
在这种情况下,Django知道哪些表格是空的而且没有改变。
如何更改我的测试或者formset的实现,以便在我的测试机器中没有失败?
