在 Django 的 admin change_form 中创建自定义按钮

2022-01-25 00:00:00 python django django-admin

问题描述

我想在管理界面的添加/更改表单中添加自定义按钮.默认只有三个:

I want to add custom buttons to the add/change form at the administration interface. By default, there are only three:

  • 保存并添加另一个

  • Save and add another

保存并继续编辑

保存

我在 forms.py 文件中创建了一些自定义方法，我想创建按钮来调用这些方法.我使用了片段 http://djangosnippets.org/snippets/1842/，但并不完全是我想要的是.这个允许从 admin.py 文件而不是 forms.py.

I have created some custom methods in my forms.py file, and I want to create buttons to call these methods. I have used the snippet http://djangosnippets.org/snippets/1842/, but it's not exactly what I want. This one allows to create buttons and call methods from the admin.py file and not forms.py.

有没有办法做到这一点?

Is there a way to do that?

这是我的 admin.py 代码:

class CategoryAdmin(admin.ModelAdmin):
    prepopulated_fields = { "alias": ("title",) }
    form = CategoryForm

admin.site.register(Category, CategoryAdmin)

还有我的 forms.py 代码，

class CategoryForm(forms.ModelForm):
    """
    My attributes
    """
    def custom_method(self):
        print("Hello, World!")

如何创建一个调用custom_method()"的按钮?

How do I create a button that calls "custom_method()"?

解决方案

您可以覆盖 admin/change_form.html.将 contrib.admin.templates 中的版本复制到您的项目中.我的是 myproject/templates/admin/change_form.html，但你可以使用 /myproject/myapp/templates/admin/change_form.html.

You can override admin/change_form.html. Copy the version in contrib.admin.templates into your project. Mine is myproject/templates/admin/change_form.html, but you could use /myproject/myapp/templates/admin/change_form.html.

接下来，编辑副本并将对现有模板标签 {% submit_row %} 的两个引用更改为指向您自己的模板标签 {% my_template_tag %}.

Next, edit the copy and change the two references to the existing template tag, {% submit_row %}, to point to your own template tag, {% my_template_tag %}.

将您的模板标签基于 contrib.admin 的 {% submit_row %}，但编辑 HTML 模板以包含您想要显示的任何额外按钮.

Base your template tag on the contrib.admin's {% submit_row %}, but edit the HTML template to contain any extra buttons you want to display.
