I am creating a django application and I have the next problem: this error is shown when I want to set a date:
我正在创建一个 django 应用程序，但我遇到了下一个问题：当我想设置日期时会显示此错误：
ValidationError [u"'12/06/2012' value has an invalid date format. It must be in YYYY-MM-DD format."]
For this model:
对于这个模型：
class ModelA(models.Model):

As @bruno as mentioned in his answer, input_formatsis a forms field, however it can be use to control the date format saved from the model.
正如@bruno 在他的回答中提到的，input_formats是一个表单字段，但它可用于控制从模型中保存的日期格式。
In settings.pyset DATE_INPUT_FORMATSas below:
在settings.py设置DATE_INPUT_FORMATS如下：
DATE_INPUT_FORMATS = ['%d-%m-%Y']
And in your form you could do something like below:
在您的表单中，您可以执行以下操作：
class ClientDetailsForm(ModelForm):
date_of_birth = DateField(input_formats=settings.DATE_INPUT_FORMATS)
class Meta:
model = ModelA

input_formatsis a forms.DateFieldoption, not a model.DateFieldoption. You have to set it in your form, not in your models.
input_formats是一种forms.DateField选择，而不是一种model.DateField选择。你必须在你的表单中设置它，而不是在你的模型中。

You could also use the LANGUAGE_CODE to get the correct date formate for the local.
LANGUAGE_CODE ='en-GB'Then have DATE_INPUT_FORMATS = ['%d-%m-%Y', '%Y-%m-%d']in the settings.pywhich can be called when needed at anytime.
您还可以使用 LANGUAGE_CODE 为本地获取正确的日期格式。
LANGUAGE_CODE ='en-GB'然后DATE_INPUT_FORMATS = ['%d-%m-%Y', '%Y-%m-%d']在settings.py需要的时候随时调用。
date_birth = forms.DateField(label='Date of birth', widget=forms.SelectDateWidget(years=YEAR_CHOICES, input_formats= DATE_INPUT_FORMATS))
date_birth = forms.DateField(label='Date of birth', widget=forms.SelectDateWidget(years=YEAR_CHOICES, input_formats= DATE_INPUT_FORMATS))
