When you need a web file manager simply create a controller and set path to managed folder via fm_root:

class FileManager < E
  include Rear
  fm_root 'path/to/files/'
end

That's all. Now you have a FileManager menu entry. Click on it to manage your files.

Text Editor

When you are dealing with files containing source code you need a specialized editor.

For now, Rear is offering support for CKEditor and Ace editors.

Before using editors you'll have to install and load corresponding gems.

See rear-ckeditor and rear-ace for instructions.

After installed and loaded, simply use fm_editor to set desired editor:

class FileManager < E
  include Rear
  fm_root 'path/to/files/'

  fm_editor :ace
  # or
  fm_editor :ckeditor
end

Menu Label

If FileManager label is not suitable, use label to set custom menu label:

class FileManager < E
  include Rear
  fm_root '../public/images'

  label :Images
end

now it will display Images in menu.

Multiple

If you have multiple folders to manage, create a controller for each one.

Optionally you can put all file managers under same menu entry by using menu grouping:

class Templates < E
  include Rear
  fm_root '../views/'
  
  menu_group :FileManager
end

class Images < E
  include Rear
  fm_root '../public/images'

  menu_group :FileManager
end

now you have FileManager menu entry that will reveal Templates and Images links on hover.
