Rules
Drupal is not about writing code
Drupal is all about features
(not those features)
"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
How to: Rules
1. Deconstruct
2. Modify
3. Construct
4. Compose
5. Trigger
Title Text
when this happens
if this is true
perform this action
Event:
Condition:
Action:
before I leave for work
if there are dark clouds in the sky
bring the umbrella from the hall
Event:
Condition:
Action:
after I leave for work
if the day is not Friday
get credit card from wallet
purchase coffee with credit card
if the time is before 8:45am
when this happens
if both of these are true
set up this data
perform this action with data
Modify
(demo)
Woah, not sure what this rule does...
I can edit this "Test" message though.
Construct
(demo)
If I unpublish a node,
delete all the comments
What Event?
Saving a node
What Condition?
If it's unpublished
What Action?
Delete the comments
Until we learn to use "Loop", we have to delete comments one-by-one
/admin/config/workflow/rules/reaction/add
When this happens...
I have an event
Add a Condition for Unpublished
What about
"unpublished"?
I want the opposite of published
Event and Condition
I Need an Action to Perform
There is no Action
referring to Comments
Comments are
Entities, though
What is all of this?
TODO
What is all of this?
I can drill down into a Node and one comment at a time
Event, Condition and Action
...but only deletes the first comment
I'll add a Loop
Drill down to comment list
Change "Current List Item" to
something more meaningful to this rule
Delete Entity needs to be nested under Loop
Don't forget to Save!
Still one more edit needed
Drill down to comment list
Change "Current List Item" to
something more meaningful to this rule
The Finished Rule
Loop over and Delete the right way
Compose
1

3
4
5
Loop
Send email to these users
Loop
Run another Rule on these Nodes
Rule Inception
Notice, there is no "Event" in a component

Useful Rules Modules
Rules Scheduler
https://www.drupal.org/project/rules
Create Components

ex. Reminder: You haven't edited your profile in a year
Views Bulk Operations

Commerce
Rules Forms Support
https://www.drupal.org/project/rules_forms
Event: When a form is being validated
Invalidate a form before it gets saved
Validate fields, display custom messages
Don't need to use Form API
Used by Resource Conflict
Resource Conflict
https://www.drupal.org/project/resource_conflict
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
Workflow Rules
https://www.drupal.org/project/workflow
React to changes in Workflow State
e.g. Draft, In Progress, Needs Review, etc.
Cache Actions
https://www.drupal.org/project/cache_actions
Clear Drupal cache bins
Clear CSS/JS cache
Clear the cache of specific views
Clear the cache of specific panel pages
Clear the cache of specific mini panels
Entityforms
https://www.drupal.org/project/entityform
Excellent Rules support built in
Rules drive email Notifications
Logintoboggan Rules
https://www.drupal.org/project/logintoboggan
Event when the user account is validated.
Organic Groups
https://www.drupal.org/project/og
Events when a user is added to a group,
Joins/Leaves a group
When group content is added
Rules Repeated Events
https://www.drupal.org/project/rules_repeated_events
My preferred means of creating recurring events.
Good example of Provided vs Parameter
Context Rules
https://www.drupal.org/project/context_rules
Event when a Context is activated,
from the Context module
