Question

我可以通过实现以下代码删除“保存并添加另一个”和“保存并继续编辑”按钮：

# At the start of my admin.py file I have:
from django.contrib.admin.templatetags.admin_modify import *
from django.contrib.admin.templatetags.admin_modify import submit_row as original_submit_row

@register.inclusion_tag('admin/submit_line.html', takes_context=True)
def submit_row(context):
    ctx = original_submit_row(context)
    ctx.update({
        'show_save_and_add_another': context.get('show_save_and_add_another', ctx['show_save_and_add_another']),
        'show_save_and_continue': context.get('show_save_and_continue', ctx['show_save_and_continue'])
        })
    return ctx

class MyModelAdmin(GuardedModelAdmin):
# Then inside MyModelAdmin I have this:
    def change_view(self, request, object_id, form_url='', extra_context=None):
        extra_context = extra_context or {}
        extra_context['show_save_and_add_another'] = False
        extra_context['show_save_and_continue'] = False
        return super(MyModelAdmin, self).change_view(request, object_id,
            form_url, extra_context=extra_context)

当我使用我的change_view时，这很有效，但是当我添加模型的新实例时，按钮会重新出现。我尝试了以下方法：

    def add_view(self, request, form_url='', extra_context=None):
        extra_context = extra_context or {}
        extra_context['show_save_and_add_another'] = False
        extra_context['show_save_and_continue'] = False
        return super(MyModelAdmin, self).add_view(self, request, form_url='', extra_context=extra_context)

但它给了我一个奇怪的MissingAtrribute错误 - 这里是追溯：

我正在使用django-guardian并想知道这是否会以某种方式导致我的问题？有没有人知道如何在添加新模型实例时从模板的submit_line部分摆脱这些恼人的按钮？

如果你想明白地隐藏这些按钮用于装饰目的，你也可以使用CSS，它可能不是最好的方法，因为你可以通过检查css来启用它们，它当然很简单，仍然足够精细，只能隐藏它们某些模特管理员。

admin.py：

class MyModelAdmin(admin.ModelAdmin)

    ....

    class Media:
        #js = ('' )  # Can include js if needed
        css = {'all': ('my_admin/css/my_model.css', )}

my_model.css位于上面路径中的静态文件文件夹中。

my_model.css：

/* Optionally make the continue and save button look like primary */
input[name="_continue"]{
    border: 2px solid #5b80b2;
    background: #7CA0C7;
    color: white;
}

/* Hide the "Delete", "Add Another" and "Save" buttons, customize this to what you need  */
.deletelink, input[name="_addanother"], input[name="_save"]{
    display: none;
}

这些按钮的django版本之间的类和名称可能会发生变化，我现在正在使用Django 1.6.6，而且我认为它们最近没有改变。如果您希望这在整个管理网站上有效，您可以将admin / base_site.html默认模板复制到静态目录中并覆盖“额外”＆＃39;阻止包括这种风格。请参阅base_site.html。

希望CSS方法有所帮助:)它肯定不会给你造成任何错误。

我有这个代码在一个小项目中工作，我不放置引用，因为我推论出了它，并且可以起作用：）

##admin.py
class Admincommits(admin.ModelAdmin):
    list_display = ["id"]
    list_filter = ["id"]
    search_fields = ["id"]
    actions = None

    def add_view(self, request, extra_context=None):
        if request.user.is_superuser:
            extra_context = extra_context or {}
            extra_context['show_save_and_continue'] = False
            #extra_context['show_save_and_add_another'] = False
            #extra_context['show_save'] = False
            #extra_context['show_delete'] = False
        return super(Admincommits, self).add_view(request, extra_context=extra_context)
