Getting Started with Editmode for Rails
Install The Gem
gem 'editmode'
Generate your config
rails generate editmode:config {project_id}
Configure caching
We use the rails cache to store content. This means if you don't have caching enabled your app will run quite slow.
# Rails 5+
rake dev:cache
Setting up cache expiration webhooks
When an editor makes changes inside the Content Hub, we need a way to let the Rails app know and expire the cache for that particular content. We use cache expiration webhooks for this. The rails gem comes pre-loaded with endpoints to receive and expire the cache, so all you have to do is configure your project settings to notify the app when content is updated.
Adding cache expiration endpoints in your project settings

One caveat is that this method obviously won’t work when working with content locally. To bring your local content in sync with remote changes on the Content Hub, you should enter Editmode and select “Clear Cache”.
Bringing local content up to date with remote changes.

We are using a method called
delete_matched
to purge your caches when a content gets updated, and this method isn’t supported in memcached
. We highly recommend using redis_store
or file_store
.- Our 2 minute explainer video below should help you understand thebasics.
- Then, to help you get kicked off, we've also added code snippetsthat you can repurpose for your app.

Setup Step 1. Create a collection in Editmode with "From", "Subject" and "Body" fields

Setup Step 2. Add a chunk to the newly created collection.

class UserMailer < BaseMailer
def editmode_email(chunk_identifier,user,variables={})
# Variables allow us to use things like "Hey {{first_name}}!"
# inside the email copy.
user_variables = {
:email => user.email,
:first_name => user.first_name,
:last_name => user.last_name
}
# Also allow other variables to be specified when the method
# is triggered
variables = user_variables.merge(variables)
to = user.email
from = Editmode.e(chunk_identifier, 'From', :variables => variables)
subject = Editmode.e(chunk_identifier, 'Subject', :variables => variables)
body = Editmode.e(chunk_identifier, 'Body', :variables => variables)
email = mail(
content_type: 'text/html',
to: to,
from: from,
subject: subject,
body: body
)
end
end
# The first argument here can take either the chunk's identifier or its content key
UserMailer.editmode_email("welcome_email",user).deliver_later
