我正在尝试为包含DateField的Django模型设置编辑表单。我已经将此字段设置为forms.py中的forms.DateInput。这对于创建模型的新实例效果很好,但是当我尝试使用现有实例填充表单时,即使所有其他字段均已正确填充,DateInput字段仍为空白。
如果我恢复为默认的TextField输入,则可以正确地调用数据。我还尝试在DateInput小部件中设置格式。
models.py
class Rider(models.Model):
first_name = models.CharField(max_length=40)
surname = models.CharField(max_length=40)
MALE = 'M'
FEMALE = 'F'
GENDER_CHOICES = [
(MALE, 'Male'),
(FEMALE, 'Female'),
]
gender = models.CharField(max_length=1, choices=GENDER_CHOICES)
dob = models.DateField("Date of Birth", auto_now = False, auto_now_add = False)
club = models.CharField(max_length=50,blank=True, null=True)
bc_number = models.IntegerField("British Cycling Membership Number", blank=True, null=True)
linked_account = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, default=1)
views.py
def rider_edit(request, pk):
rider = get_object_or_404(Rider, pk=pk)
if request.method == "POST":
form = RiderForm(request.POST, prefix='rider', instance=rider)
if form.is_valid():
rider = form.save(commit=False)
rider.linked_account = request.user
rider.save()
return redirect('rider_list')
else:
form = RiderForm(prefix='rider', instance=rider)
return render(request, 'riders/rider_new.html', {'riderform': form})
form.py
from django import forms
from .models import Rider, MedicalInfo
class RiderForm(forms.ModelForm):
class Meta:
model = Rider
fields = ('first_name', 'surname', 'gender', 'dob', 'club', 'bc_number')
widgets= {
'dob': forms.DateInput(attrs={'type': 'date'}, format='%d/%m/%Y')
}
rider_new.html
<h2>New Rider</h2>
<form method="POST" class="post-form">
{% csrf_token %}
{{ riderform.as_p }}
<button type="submit" class="save btn btn-default">Add Rider</button>
</form>
dob字段是唯一未从数据库正确填充的字段,它应以dd / mm / YYYY格式显示日期,例如“ 2010年10月9日”。实际上是显示默认的“ dd / mm / YYYY”。
答案 0 :(得分:0)
我找到了解决该问题的方法,数据库中的日期以“%d /%m /%Y”格式返回,但是表单上的输入为“ date”类型,期望在格式更改为“%Y-%m-%d”,
widgets= {
'dob': forms.DateInput(format=('%d/%m/%Y'), attrs={'class':'form-control', 'placeholder':'Select Date','type': 'date'})
}
收件人:
widgets= {
'dob': forms.DateInput(format=('%Y-%m-%d'), attrs={'class':'form-control', 'placeholder':'Select Date','type': 'date'})
}
因此,生成的HTML表单从:
<input type="date" name="rider-dob" value="10/09/2010" class="form-control" placeholder="Select Date" required="" id="id_rider-dob">
收件人:
<input type="date" name="rider-dob" value="2010-09-10" class="form-control" placeholder="Select Date" required="" id="id_rider-dob">
