问题描述

如何在django管理员的内联中设置第一个默认行/值?

How to set first default rows/values in django admin's inline?

    class Employee(models.Model):
        username = models.CharField(_('Username'), max_length=150, null=False, blank=False)
        email = models.CharField(_('Email'), max_length=150, null=False, blank=False)

    class Details(models.Model):
        employee = models.ForeignKey(Employee, verbose_name=_('Employee'), blank=False, null=False)
        label = models.CharField(_('Label'), max_length=150, null=False, blank=False)
        value = models.CharField(_('Value'), max_length=150, null=False, blank=False)


    class DetailsFormset(forms.models.BaseInlineFormSet):
        def __init__(self, *args, **kwargs):
                self.initial = [
{ 'label': 'first name'},  
{'label': 'last name'}, 
{'label': 'job',}]
            super(DetailsFormset, self).__init__(*args, **kwargs)

    class DetailsInline(admin.TabularInline):
        model = Details
        formset = DetailsFormset
        fieldsets = [
                ['', {'fields': ['employee', 'label', 'value']}]
        ]

    class EmployeeAdmin(admin.ModelAdmin):
        inlines = [DetailsInline]

但此行不起作用

    self.initial = [
{ 'label': 'first name'},  
{'label': 'last name'}, 
{'label': 'job',}]

如何使用django admin设置默认值?

How do I set default values using django admin?

推荐答案

from django.utils.functional import curry

class DetailsInline(admin.TabularInline):
    model = Details
    formset = DetailsFormset
    extra = 3

    def get_formset(self, request, obj=None, **kwargs):
        initial = []
        if request.method == "GET":
            initial.append({
                'label': 'first name',
            })
        formset = super(DetailsInline, self).get_formset(request, obj, **kwargs)
        formset.__init__ = curry(formset.__init__, initial=initial)
        return formset

从此处:预填充内联FormSet?
