No image upload capability in UI with CKEditor gem, Paperclip Rails 4

Question

I'm using the ckeditor gem (https://github.com/galetahub/ckeditor), and paperclip gem, and CKEditor works, but I have no option to upload an image when I click the image button, only enter a URL. I can't find any documentation that explains how to do this with Paperclip and Rails 4.

Answer 1

There is an issue that describes the problem:.

A solution is to copy the content of the config.js from there.

Answer 2

Just modify config. solution from @KrauseFx

    CKEDITOR.editorConfig = function( config )
    {
        // Define changes to default configuration here. For example:
        // config.language = 'fr';
        // config.uiColor = '#AADC6E';

        /* Filebrowser routes */
        // The location of an external file browser, that should be launched when "Browse Server" button is pressed.
        config.filebrowserBrowseUrl = "/ckeditor/attachment_files";
