我的 form.py 文件中有一个表单类,我在其中启动了表单字段的属性。我想将“描述”字段从输入字段更改为高度为 5 行的文本区域字段。还想将我的“截止日期”字段更改为日期输入字段,因为目前它是输入文本字段。
class JobPost_form(ModelForm):
class Meta:
model = Job_post
fields = "__all__"
def __init__(self, *args, **kwargs):
self.fields['Job_role'].widget.attrs.update(
{'class': 'form-control Password2', 'id': 'form3Example1c', 'placeholder': 'Job role'})
self.fields['Company'].widget.attrs.update(
{'class': 'form-control', 'id': 'form3Example1c', 'placeholder': 'Company'})
self.fields['Deadline'].widget.attrs.update(
{'class': 'form-control', 'id': 'form3Example1c', 'placeholder': 'YYYY-MM-DD HH:MM:SS'})
self.fields['Description'].widget.attrs.update(
{'class': 'form-control', 'id': 'form3Example1c', 'placeholder': 'Description'})
我认为在您传递的代码中缺少表格,因为元和 init 将位于类中:JobPost_form。至于将描述字段标记为文本区域,您应该这样做:
class JobPost_form(ModelForm):
description = forms.CharField(widget=forms.TextInput(attrs={"class": "form-control"}))
class Meta:
model = Job_post
fields = "__all__"
def __init__(self, *args, **kwargs):
...
您可以使用 django 在表单 api 中提供的 wigets(attrs="{}") 来实现这些事情
class DemoClass(models.Model):
description = models.TextField()
deadline = models.DateField()
class DemoForm(forms.ModelForm):
class Meta:
model = DemoClass
fields = "__all__"
widgets={
'description':forms.Textarea(attrs={"rows":"4", "cols":"50"}),
'deadline':forms.TextInput(attrs={'type':'date'}),
--------------- OR -------------------------------
'deadline':forms.DateInput(attrs={'type':'date'}),
}
{% block body %}
<div class="container">
<div class="row">
<div class="col-lg-12">
{{form.as_p}}
</div>
</div>
</div>
{% endblock body %}
我找到了一种完全改变输入的方法。在此代码中,我将其更改为 type=range 并向其中添加了引导类。
class RangeBooted(Input):
def get_context(self, name, value, attrs):
ctx = super(RangeBooted, self).get_context(name, value, attrs)
ctx['widget']['type'] = "range"
ctx['widget']['attrs']['class'] = "form-range bg-secondary rounded shadow w-75 p-2"
ctx['widget']['attrs']['min'] = "0"
ctx['widget']['attrs']['max'] = "100"
ctx['widget']['attrs']['step'] = "2"
return ctx
