ECA

Custom Code

ECA

Declarative over Imperative

Describe the functionality you want instead of hard coding it.

Would you rather order a sandwich or have to write a step by step tutorial for how to make a sandwich before you can order it?

Maintainability

Fewer moving parts, fewer security patches. Fewer things become obsolete when Drupal gets a major version.

The Phone Loophole

I could walk you through changing things over the phone.

Change Business Logic without a

deploy

Promotions, deal of the day, move at the speed of thought.

 

If you have true CI/CD this is less of an issue.

Drupal is not about writing code

Drupal is all about functionality

"using the internet to eliminate middlemen"

Dries Buytaert

the programmer is a middleman between your data and your business

not knowing how to code can be as bad as having as having a middle man

If it's unpublished

What Action?

Send a message to each commenter

  • Load a list of all comments
  • Get one item from the list
  • Email the Author
  • Load Next Item? (later)

/admin/config/workflow/eca/add

1. Name your Model

 

 

 

 

2. Add a description

/admin/config/workflow/eca/add

3. Circle = Event

 

"When this happens..."

4. I have an event,

give it a Name

This is the "Condition"

from Event-Condition-Action

Event, Condition and Action

...but only emails the first commenter?

I've Pressed Them All

Except One...

Gateway is where

a branch or a loop

starts

 

Adding the Gateway is the

final form for our Model

to loop over all the comments on a node

"Load Comment" action can only grab one comment at a time, it has no idea how many items are in the list, or what's left

Don't Forget to Save!

In a Perfect World™

We make sure this Node was published and is being unpublished...

Useful ECA Resources

ECA Guide

 

Config Ignore

drupal.org/project/config_ignore

drupal.org/project/config_readonly

If you want to edit ECA in Production

Run ECA on Cron

e.g. Scheduled Publish

ecaguide.org/library/simple/scheduled_publishing

The "Event" is Cron

e.g. Reminder: You haven't edited your profile in a year

Views Bulk Operations

https://www.drupal.org/project/eca_vbo

Create Custom Display

Does not play nice with regular VBO

Access Check

Must enable each new Event in View Config

Maillog

drupal.org/project/maillog

Show me the emails

Log all messages

Reroute instead of sending

Commerce

drupal.org/project/eca_commerce

Enabling Payment Types

Adding Taxes

Price Adjustments

ECA Forms Support

ECA Forms
drupal.org/project/eca_webform

Resource Conflicts

https://events.drupal.org/portland2024/session/unleashing-power-eca-no-code-coding-ambitious-site-builders

Check if an event is in the same room at the same time

Use Taxonomy Terms for "rooms"

Can invalidate the form, so it won't be saved if a conflict exists

Copy of Rules:Duct Tape for Drupal

By Ryan Price

Copy of Rules:Duct Tape for Drupal

The Rules module - the duct tape of Drupal - use it to build new features and business logic. Rules can be immensely useful for Intranet websites, or sites with complicated sets of permissions and publishing workflows. It is also used by default in Drupal Commerce sites to manage taxes, discounts and payment types. Not sure if you need Rules? Are you ... a Site Builder, but not a coder? a Drupal Commerce User? starting or ending a sale on a certain Date? an Organic Groups Admin? sending E-Mail notifications from your site? creating repeating Events? creating Views Bulk Operations actions? flagging Nodes as spam, based on user feedback? This session will provide you with: a formula you can apply to decide when to use rules a system for asking the right questions before you create a rule how to find examples of similar rules you can modify modules that provide extra actions and conditions rules that can be helpful in specialized sites, like commerce sites, event-driven sites or community sites
