Python 使用filerImageField上载图像

我得到了简单的表格。我想保存图像，然后在模板中渲染它。 表单工作正常。所有值都将被存储和呈现。 当我点击“选择图像”时，我会被重定向到admin/filer/folder/ 我可以选择图像并保存它。比我不能选择它。如果我点击它，我只能更改设置。若我将图像拖放到模板中的字段中，则在提交表单“选择有效选项”时会出现错误

图像的路径是绝对路径。您需要提供一个相对路径，它将被添加到您的媒体文件夹中：

class Blog_post(CMSPlugin):
    category = models.ForeignKey(Category)
    style = models.ForeignKey(Blog_style)
    title = models.CharField(max_length=200, default='title')
    description = models.CharField(max_length=200,default='description')
    image = models.ImageField(upload_to='images/', null=True, blank=True)
    text = RichTextField()
    created_date = models.DateTimeField(
            default=timezone.now)
    published_date = models.DateTimeField(
            blank=True, null=True)

查看文档的示例：

class MyModel(models.Model):
    # file will be uploaded to MEDIA_ROOT/uploads
    upload = models.FileField(upload_to='uploads/')
    # or...
    # file will be saved to MEDIA_ROOT/uploads/2015/01/30
    upload = models.FileField(upload_to='uploads/%Y/%m/%d/')

---

我认为你混合了两件事：

如中所述，直接在models.py中使用

FilerFileField

或

FilerImageField

在CKEDITOR中使用文件管理器：（详细说明了实现）

不过，您是对的，管理员之外的文件服务器管理似乎只是github发布的问题，它为我提供了解决方案：

首先，在模板html文件中添加

{{form.media}

，就在 标记

和

{%csrf\u令牌%}

。然后在中扩展媒体类 您的

forms.py的
ModelForm

我已经试过了，没用。谢谢你的帮助，还有其他想法吗？你能检查一下媒体文件夹吗？图像是否在您指向的文件夹中创建？不，没有…我不确定问题出在哪里，我拥有所有权限。提交后请尝试打印表单，并在保存帖子对象之前检查图像字段的值。你得到什么值？我得到一个图像名称和格式。但当我单击save时，img不会被保存。
