Rails Integration for TinyMCE
The tinymce-rails
gem integrates the TinyMCE editor with the Rails asset pipeline.
This gem is compatible with Rails 4.2 and higher.
This is the branch for TinyMCE 5. For TinyMCE 4, please see the tinymce-4 branch, and for TinyMCE 3.5.x, please see the tinymce-3 branch.
New in 3.5.11, 4.1.10 and 4.2.1: Alternative asset installation methods (copy vs compile/symlink). See the Asset Compilation section below for details.
Instructions
1. Add tinymce-rails
to your Gemfile
gem 'tinymce-rails'
Be sure to add to the global group, not the assets
group. Then run bundle install
.
2. Create a config/tinymce.yml
file with your global configuration options:
toolbar:
- styleselect | bold italic | undo redo
- image | link
plugins:
- image
- link
The Rails server no longer needs to be restarted when this file is updated in development mode.
To define multiple configuration sets, follow this syntax (a default configuration must be specified):
default: &default
plugins:
- image
- link
alternate:
<<: *default
toolbar: styleselect | bold italic | undo redo | table
plugins:
- table
See the TinyMCE 5 Documentation for a full list of configuration options.
3. Include the TinyMCE assets
Use one of the following options to include TinyMCE assets.
(1) Add to your application.js:
or (2) with jQuery integration:
(3) The TinyMCE assets can be included on a per-page basis using the tinymce_assets
helper:
<%= tinymce_assets %>
#=> <script type="text/javascript" src="/assets/tinymce.js">
4. Initialize TinyMCE
For each textarea that you want to use with TinyMCE, add the "tinymce" class and ensure it has a unique ID:
<%= text_area_tag :content, "", :class => "tinymce", :rows => 40, :cols => 120 %>
or if you are using Rails' form builders:
<%= f.text_area :content, :class => "tinymce", :rows => 40, :cols => 120 %>
Then invoke the tinymce
helper to initialize TinyMCE:
<%= tinymce %>
Custom options can be passed to tinymce
to override the global options specified in config/tinymce.yml
:
<%= tinymce :theme => "simple", :language => "de", :plugins => ["wordcount", "paste"] %>
Alternate configurations defined in 'config/tinymce.yml' can be used with:
<%= tinymce :alternate %>
Language Packs
See the tinymce-rails-langs gem for additional language packs for TinyMCE.
Manual Initialization
Using the tinymce
helper and global configuration file is entirely optional. The tinyMCE.init
function can be invoked manually if desired.
<%= text_area_tag :editor, "", :rows => 40, :cols => 120 %>
<script type="text/javascript">
tinyMCE.init({
selector: 'textarea.editor'
});
</script>
Asset Compilation
Since TinyMCE loads most of its files dynamically, some workarounds are required to ensure that the TinyMCE asset files are accessible using non-digested filenames.
As of tinymce-rails 3.5.11, 4.1.10 and 4.2.1, two alternative asset installation methods are available, which can be changed by setting config.tinymce.install
within your config/application.rb
file. These methods are called when you run rake asset:precompile
(via Rake::Task#enhance
) after the regular application assets are compiled.
The default method (as of 4.5.2), compile
, adds the TinyMCE paths to the Sprockets precompilation paths and then creates symlinks from the non-digested filenames to their digested versions.
config.tinymce.install = :compile
If you experience issues with the compile
method, you may wish to use the copy
method instead, which copies the TinyMCE assets directly into public/assets
and appends the file information into the asset manifest. The copy_no_preserve
method is also available of you do not wish to or cannot preserve file modes on your filesystem.
config.tinymce.install = :copy
If you are including TinyMCE via application.js
or using the tinymce_assets
helper, you do not need to manually alter the precompile paths. However if you wish to include tinymce-jquery.js
independently (i.e. using javascript_include_tag
), you will need to add it to the precompile list in config/environments/production.rb
:
config.assets.precompile << "tinymce-jquery.js"
Custom Plugins & Skins
To use custom plugins or skins, simply add the files to your asset load path so that they are locatable at a path beneath tinymce/plugins/
or tinymce/skins/
.
For example, a plugin called mycustomplugin
could have its main JS file at app/assets/javascripts/tinymce/plugins/mycustomplugin/plugin.js
.
You should also ensure that your custom paths are added to the asset precompile paths.
Using tinymce-rails as an Engine Dependency
Ensure that you explicitly require tinymce-rails
within your engine file. Including tinymce-rails as a dependency in your gemspec is not enough.
Updating
When new versions of TinyMCE are released, simply update the tinymce-rails
gem to the latest version. There is no need to run any extra rake tasks (apart from rake assets:precompile
).
