python - Django 如何将初始对象设置为 ModelList？

Question

我创建了一个简单的模型

class Person(models.Model):
    name = models.CharField(max_length=25)
    surname = models.CharField(max_length=25)
    birth_date = models.DateField()
    ...

和一个简单的ModelForm

class PersonForm(ModelForm):
class Meta:
    model = Person

如何将已有的 Person 对象(例如 Person.objects.get(pk=1))设置为表单的初始值？我需要编辑这个对象

Answer 1

来自文档:

# Creating a form to add an article.
>>> form = ArticleForm()

# Creating a form to change an existing article.
>>> article = Article.objects.get(pk=1)
>>> form = ArticleForm(instance=article)

所以在你的情况下，在你的 views.py 中:

person = Person.objects.get(pk=1)
form = PersonForm(instance=person)
