使用CKEditor，BLOB字段和Rails 4自定义上传图像

Question

I'm currently using CKEditor in my site. The user may upload some images to the server using the button for Upload Image in the CKEditor.

There is a textarea field with id #article_conteudo on the page that uses the CKEditor, here is the javascript code to configure the editor:

CKEDITOR.replace('article_conteudo', {
    filebrowserImageUploadUrl: '/article/upload/'
});

The URL /article/upload/ points to a method file_upload in an articles_controller :

def file_upload
    image = ArticlesImage.new

    image.imagem = params[:upload].read

    image.save
end

The images are stored in a BLOB field in a MySQL Database.

The images are saved in the database with no problems. But, after saving, nothing happens in the Editor. I'm not sure what is the expected response for the Upload Action of the CKEditor on this case. I'm not sure, also, if CKEditor uploads support the use of BLOBs.

How can I implement this functionality in my project?

If it can't be done with CKEditor, is there any other plugin that can do it?

Thanks for your help

PS: The use of BLOB is MANDATORY for the project, I cannot use other methods

Answer 1

it depends of what you need.

If you want to display images on your browser, you have to create the JSON response involved.

And then, the fileUploadResponse of the CKEditor would be able to display your images (or files) on your editor.
