Question

当我尝试将图像插入我的博客时，我选择上传标签并选择我的文件和Send it to Server。然后在URL选项卡中选择Browse Server，我收到以下错误：

ActiveRecord::StatementInvalid in Ckeditor::AttachmentFilesController#index

PG::Error: ERROR:  relation "ckeditor_assets" does not exist
LINE 5:              WHERE a.attrelid = '"ckeditor_assets"'::regclas...
                                    ^
:             SELECT a.attname, format_type(a.atttypid, a.atttypmod),
                 pg_get_expr(d.adbin, d.adrelid), a.attnotnull, a.atttypid, a.atttypmod
          FROM pg_attribute a LEFT JOIN pg_attrdef d
            ON a.attrelid = d.adrelid AND a.attnum = d.adnum
         WHERE a.attrelid = '"ckeditor_assets"'::regclass
           AND a.attnum > 0 AND NOT a.attisdropped
         ORDER BY a.attnum

任何想法？

修改

我跳过上述问题的迁移。但我还是无法上传文件。我收到了这个错误：

Started POST "/ckeditor/attachment_files? CKEditor=blog_entry_body&CKEditorFuncNum=1&langCode=en" for 127.0.0.1 at 2013-05-24 18:10:29 -0500

看起来好像发生在Ckeditor::AttachmentFilesController#create。但是当我安装CKEditor gem时，我没有看到这个控制器生成。我在另一篇文章中发现我必须skip_before_filter :verify_authenticity_token，但就像我说的那样，我没有看到Ckeditor::AttachmentFilesController#create。

Answer 1

SQL是ActiveRecord用来确定PostgreSQL表的结构，从而得出ActiveRecord::Base子类的属性。＆＃34;关系不存在＆＃34;错误意味着您有一个CkeditorAsset ActiveRecord类（因此ckeditor_assets表名）但不是ckeditor_assets表。您在某个地方错过了迁移，也许有一个生成器用于初始化您忘记运行的CKEditor插件。

Rails，CKEditor，PostgreSQL，使用Carrierwave上传图片
