默认情况下需要 Django 模型表单吗，以及如何将整个表单的 required 设置为 false?

Question

>models.py：

class Venue(models.Model):
author = models.ForeignKey(ProfileUser, on_delete=models.CASCADE)
title = models.CharField(max_length=300)
city = models.ForeignKey(City, on_delete=models.CASCADE)
address = models.CharField(max_length=300)
phone = models.CharField(max_length=20, default='')
email = models.CharField(max_length=100, default='')
site = models.CharField(max_length=100, default='')
facebook = models.CharField(max_length=100, default='')
instagram = models.CharField(max_length=100, default='')
content = models.TextField()
rating = models.DecimalField(default=10.0, max_digits=5, decimal_places=2)
created_date = models.DateTimeField(default=timezone.now)
approved_venue = models.BooleanField(default=False)
admin_seen = models.BooleanField(default=False)
category = models.ForeignKey(Category, on_delete=models.CASCADE)
def __str__(self):
return f"{self.title}"

forms.py

class VenueForm(forms.ModelForm):
class Meta:
model = Venue
fields = [
'title',
'content',
'city',
'address',
'phone',
'email',
'site',
'facebook',
'instagram',
]
def __init__(self, *args, **kwargs):
super(VenueForm, self).__init__(*args, **kwargs)
self.fields['title'].label = "Име"
self.fields['content'].label = 'Описание'
self.fields['city'].label = 'Град'
self.fields['address'].label = 'Адрес'
self.fields['phone'].label = 'Телефон'
self.fields['email'].label = 'E-mail'
self.fields['site'].label = 'Сайт'

HTML 渲染：

<form method="post" id="dialog_addVenue_part" enctype="multipart/form-data">
{% csrf_token %}
{% for hidden in postForm.hidden_fields %}
{{ hidden }}
{% endfor %}
{% for field in form %}
<div class="fieldWrapper">
<div class="errorcode{{field.html_name}}">
{{ field.errors }}
</div>
{{ field.label_tag }} {{ field }}
{% if field.help_text %}
<p class="help">{{ field.help_text|safe }}</p>
{% endif %}
</div>
{% endfor %}
<div id="map" style="height: 500px;">
</div>
<div class="utf_addVenue_form">
<button type="submit" value="Изпрати">Изпрати</button>
</div>
</form>

带有必填字段的 HTML 部分：

<div class="fieldWrapper">
<div class="errorcodesite">
</div>
<label for="id_site">Сайт:</label> <input type="text" name="site" maxlength="100" required="" id="id_site">
</div>
<div class="fieldWrapper">
<div class="errorcodefacebook">
</div>
<label for="id_facebook">Facebook:</label> <input type="text" name="facebook" maxlength="100" required="" id="id_facebook">
</div>

我没有在任何地方指出表单应该对所有字段都有"必需"，但它们随之而来。那么，默认情况下需要 Django 模型表单吗，以及如何将整个表单的 required 设置为 false？

Answer 1

将blank=True添加到不需要的字段中。

class Venue(models.Model):
. . .
title = models.CharField(max_length=300, blank=True)
