Django Admin中的动态字段 [英] Dynamic fields in Django Admin

问题描述

我想要有一个字段的值的附加字段。因此，我建立一个自定义的管理表单来添加一些新的领域。

I want to have additional fields regarding value of one field. Therefor I build a custom admin form to add some new fields.

与jacobian的博客相关 1 这是我想出的：

Related to the blogpost of jacobian 1 this is what I came up with:

class ProductAdminForm(forms.ModelForm):
    class Meta:
        model = Product

    def __init__(self, *args, **kwargs):
        super(ProductAdminForm, self).__init__(*args, **kwargs)
        self.fields['foo'] = forms.IntegerField(label="foo")

class ProductAdmin(admin.ModelAdmin):
    form = ProductAdminForm

admin.site.register(Product, ProductAdmin)

但是，附加字段foo不会显示在管理员中。如果我添加这样的字段，一切都可以正常工作，但不如所需的动态，添加关于模型的另一个字段的值的字段

But the additional field 'foo' does not show up in the admin. If I add the field like this, all works fine but is not as dynamic as required, to add the fields regarding the value of another field of the model

class ProductAdminForm(forms.ModelForm):

    foo = forms.IntegerField(label="foo")

    class Meta:
        model = Product

class ProductAdmin(admin.ModelAdmin):
    form = ProductAdminForm

admin.site.register(Product, ProductAdmin)

是否有任何初始化方法，我必须再次触发，使新的字段工作？还是有任何其他尝试？

So is there any initialize method that i have to trigger again to make the new field working? Or is there any other attempt?

推荐答案

这是解决问题的方法。感谢koniiiik，我尝试通过扩展* get_fieldsets *方法来解决这个问题。

Here is a solution to the problem. Thanks to koniiiik i tried to solve this by extending the *get_fieldsets* method

class ProductAdmin(admin.ModelAdmin):
    def get_fieldsets(self, request, obj=None):
        fieldsets = super(ProductAdmin, self).get_fieldsets(request, obj)
        fieldsets[0][1]['fields'] += ['foo'] 
        return fieldsets

如果您使用多个字段，请确保添加通过使用适当的索引到正确的字段集。

If you use multiple fieldsets be sure to add the to the right fieldset by using the appropriate index.
