如何在Django管理中需要内联？ [英] How do I require an inline in the Django Admin?

问题描述

我有以下管理员设置，以便我可以同时添加/编辑用户及其个人资料。

I have the following admin setup so that I can add/edit a user and their profile at the same time.

class ProfileInline(admin.StackedInline):
    """
    Allows profile to be added when creating user
    """
    model = Profile


class UserProfileAdmin(admin.ModelAdmin):
    """
    Options for the admin interface
    """
    inlines = [ProfileInline]
    list_display = ['edit_obj', 'name', 'username', 'email', 'is_active',
        'last_login', 'delete_obj']
    list_display_links = ['username']
    list_filter = ['is_active']
    fieldsets = (
        (None, {
            'fields': ('first_name', 'last_name', 'email', 'username',
                'is_active', 'is_superuser')}),
        )
    ordering = ['last_name', 'first_name']
    search_fields = ['first_name', 'last_name']

admin.site.register(User, UserProfileAdmin)

问题是，在添加用户时，需要配置文件内联表单中的两个字段。除非输入输入，内联表单不会验证。有没有要进行内联要求，所以不能留空？

The problem is I need two of the fields in the Profile inline form to be required when adding the user. The inline form doesn't validate unless input is entered. Is there anyway to make the inline required, so that it can't be left blank?

推荐答案

我拿着卡尔的建议，一个更好的实现，那么我在我的评论中提到的hack-ish他的答案。这是我的解决方案：

I took Carl's advice and made a much better implementation then the hack-ish one I mentioned in my comment to his answer. Here is my solution:

从我的forms.py：

From my forms.py:

from django.forms.models import BaseInlineFormSet


class RequiredInlineFormSet(BaseInlineFormSet):
    """
    Generates an inline formset that is required
    """

    def _construct_form(self, i, **kwargs):
        """
        Override the method to change the form attribute empty_permitted
        """
        form = super(RequiredInlineFormSet, self)._construct_form(i, **kwargs)
        form.empty_permitted = False
        return form

和admin.py

class ProfileInline(admin.StackedInline):
    """
    Allows profile to be added when creating user
    """
    model = Profile
    extra = 1
    max_num = 1
    formset = RequiredInlineFormSet


class UserProfileAdmin(admin.ModelAdmin):
    """
    Options for the admin interface
    """
    inlines = [ProfileInline]
    list_display = ['edit_obj', 'name', 'username', 'email', 'is_active',
        'last_login', 'delete_obj']
    list_display_links = ['username']
    list_filter = ['is_active']
    fieldsets = (
        (None, {
            'fields': ('first_name', 'last_name', 'email', 'username',
                'is_active', 'is_superuser')}),
        (('Groups'), {'fields': ('groups', )}),
    )
    ordering = ['last_name', 'first_name']
    search_fields = ['first_name', 'last_name']


admin.site.register(User, UserProfileAdmin)

这完全是我的想要，这使得Profile inline formset被验证。因此，由于在配置文件表单中有必填字段，所以如果没有在内联表单中输入所需的信息，它将被验证并失败。

This does exactly what I want, it makes the Profile inline formset validate. So since there are required fields in the profile form it will validate and fail if the required information isn't entered on the inline form.
