tinymce-rails-imageupload
Simple plugin for TinyMCE that allows uploading images and inserting. It makes no assumptions about how you store the images, but it POSTs to a URL and expects JSON back (see the Setup section).
This plugin borrows heavily from work done by Peter Shoukry.
The icon used for the button comes from the icon set Silk by famfamfam
Requirements
- Rails >= 3.1
- TinyMCE using the advanced theme and jQuery
Setup
Add the gem to your Gemfile
gem 'tinymce-rails-imageupload', '~> 3.4.8'
Set up TinyMCE as you would normally, but in the call to .tinymce()
, add
plugins: "uploadimage"
# theme_advanced_buttonsX must include "uploadimage" somewhere to have the button appear
and the rest should happen automatically.
The plugin POSTs to /tinymce_assets
by default, which is currently not configurable (issue #3).
Set it up using something similar in routes.rb
post '/tinymce_assets' => 'tinymce_assets#create'
This action gets called with a file parameter creatively called file
, and must respond with JSON, containing the URL to the image.
The JSON has to be returned with a content type of "text/html" to work, which is going to be fixed as soon as possible (issue #7).
Example:
class TinymceAssetsController < ApplicationController
def create
# Take upload from params[:file] and store it somehow...
render json: {
image: {
url: view_context.image_url(image)
}
}, content_type: "text/html"
end
end
If the JSON response contains a width
and/or height
key, those will be used in the inserted HTML (<img src="..." width="..." height="...">
), but if those are not present, the inserted HTML is just <img src="...">
.
Internationalization
I18n is taken care of by tinymce-rails
. This gem includes strings for English and Norwegian.
To add your own language, create the files <code>.js
and <code>_dlg.js
in vendor/assets/javascripts/tinymce/plugins/uploadimage/langs
in your application,
or fork the gem and add your own translations there.
The available strings are listed below:
en.js
tinyMCE.addI18n('en.uploadimage', {
desc: 'Insert an image from your computer'
});
en_dlg.js
tinyMCE.addI18n('en.uploadimage_dlg', {
title: 'Insert image',
header: "Insert image",
input: "Choose an image",
insert: "Insert",
cancel: "Cancel"
});
Versioning
The version of this gem will be mirroring the release of tinymce-rails
it is tested against.
