This repository is no longer maintained, as I do not use TinyMCE for anything any more. I also understand that TinyMCE 4 is quite old. Luckily, Frank Groeneveld has written a blog post detailing how to get image uploads working with TinyMCE 6 and Rails that I recommend checking out.
This version is being rewritten to work with TinyMCE 4.x, and is
currently not very tested. Use at your own risk, feedback welcome. For the stable version targetting TinyMCE 3, see
the tinymce3 branch
Simple plugin for TinyMCE that allows uploading images and inserting. It makes no assumptions about how you store the images, it simply POSTs to a URL and expects JSON back (see the Setup section).
This plugin started as a copy of work done by Peter Shoukry, but has since mutated into something entirely different.
Support for TinyMCE 3 is currently available in the tinymce3 branch. The master branch is targetting TinyMCE 4.x.
A small demo app demonstrating a working setup for Rails 3.2 (demo, source), and for Rails 4 (demo, source) is available for study.
- Rails >= 3.1
- TinyMCE4 using the advanced theme
gem 'tinymce-rails-imageupload', '~> 4.0.0.beta'
# or use git
gem 'tinymce-rails-imageupload', github: 'PerfectlyNormal/tinymce-rails-imageupload'
plugins: "uploadimage"
# toolbar option must include "uploadimage" somewhere to have the button appear
and the rest should happen automatically.
You can also globally have imageupload globally disabled but enabled on specific instances.
# tinymce.yml
toolbar: bold italic underline | uploadimage
plugins:
- uploadimage
uploadimage: false<%= tinymce uploadimage: true %>The plugin defaults to POSTing to /tinymce_assets. You may modify it by
supplying the option uploadimage_form_url in the call to .tinymce()
Routing to your controller must be done manually.
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 hopefully going to be fixed (issue #7).
Example:
class TinymceAssetsController < ApplicationController
def create
# Take upload from params[:file] and store it somehow...
# Optionally also accept params[:hint] and consume if needed
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="...">.
Per request hint data can be sent to the create action through the call to .tinymce() or tinymce.yml. You may use this to relay any hints you wish (for example, blog post ID #) to the controller.
uploadimage_hint_key- override the hint key. Default ishint.uploadimage_hint- hint value.
Example:
<%= tinymce uploadimage_hint_key: 'post_id', uploadimage_hint: @post.id %>Would result in a params object that looks like this:
{
"post_id": 1,
"file": ...,
// ...
}Params can be sent in a more standard attributes format by setting uploadimage_model.
uploadimage_model- nest attributes within model namespace.
Example:
<%= tinymce uploadimage_model: 'post' %>Would result in a params object that looks like this:
{
"post": {
"file": ...,
// ...
},
}By default the plugin doesn't assign any class to the img tag.
You can set the class(es) by supplying the uploadimage_default_img_class
option in the call to .tinymce().
class="..." will only be added to the img tag if a default or custom class is specified.
Otherwise the inserted HTML is just <img src="...">.
You can set image_class_list to an array of title, value objects to provide uploaders a pre-defined list of CSS classes to apply.
# tinymce.yml
image_class_list:
- title: 'Center'
value: 'img-center'
- title: 'Left thumbnail'
value: 'img-left img-thumbnail'
- title: 'Right thumbnail'
value: 'img-right img-thumbnail'Several people have had trouble with asset precompilation using the asset pipeline, both for the locales, and the plugin itself.
Depending on your version of Rails, and the alignment of the moon, it might work out of the box, or you'll have to add something like this in your configuration:
config.assets.precompile += %w( tinymce/plugins/uploadimage/plugin.js tinymce/plugins/uploadimage/langs/en.js )
Obviously adjust depending on the language or languages you want to use.
Since TinyMCE doesn't know about the asset pipeline however, you could just place it under public/, and that should probably work as well. As with all things Rails and assets related, YMMV.
To notify the uploader that an error occurred, return JSON containing an
error key with a message. The message gets show in a paragraph with the
ID error_message, and the input label gets the class invalid.
Example response:
"{"error": {
"message": "Invalid file type. Only .jpg, .png and .gif allowed"
}}"
I18n is taken care of by tinymce-rails.
This gem includes strings for en, de, es, fr, nb, pt, pt_BR,
ru and zh-cn.
To add your own language, create the files <code>.js in
app/assets/javascripts/tinymce/plugins/uploadimage/langs in your
application, or fork the gem and add your own translations there.
The format and available strings are listed below:
tinyMCE.addI18n('nb', {
'Insert an image from your computer': 'Sett inn et bilde fra datamaskinen',
'Insert image': "Sett inn bilde",
'Choose an image': "Velg et bilde",
'You must choose a file': "Du m\u00e5 velge en fil",
'Got a bad response from the server': "Fikk et ugyldig svar fra serveren",
"Didn't get a response from the server": "Fikk ikke svar fra serveren",
'Insert': "Sett inn",
'Cancel': "Avbryt",
'Image description': "Alternativ tekst for bilde",
});
The major, minor and patch version of this gem will be mirroring the
release of tinymce-rails it is tested against.
