The following table presents all properties available at the top level of the YAML for the app. file.įor reference, see a log of changes to app configuration. See a comprehensive example of a configuration in a. Multi-app projects can be set up in various ways. Usually located at the root of your app folder in your Git repository. Combine with loops, actions and Rules Scheduler to make awesomeness happen.See all of the options for controlling your apps and how they’re built and deployed on Platform.sh.įor single-app projects, the configuration is all done in a. The action provides a list of entities, that can be used just like other lists in Rules.(This is available under the “Views bulk operations” group.) All view displayes with at least one VBO field will be selectable. You need a rule that, as an action, loads entities from a VBO.Note that you don’t need any actions enabled for the field – it is enough that it is present. The type of bulk operations field determines what entity type will be sent to Rules. However, you need one bulk operations field.Note that you don’t need a display of the view – and it might even be better not to have one if you don’t want the view to be displayed somewhere. You need a view that lists the entities you want to work on in Rules.To do similar cools stuff yourself, the following steps may be useful: As an example, a rule is set up that, once a day, removes any stick front page content that is older than one week.

This screencast shows the awesome functionality of loading entity lists into Rules with help of VBO.

If you have a component with several parameters matching the view type, the first one will be auto-populated by VBO – the rest you have to set manually.

In that case, you’ll have to specify all the parameters manually.

You can use Rules components without any parameters matching the View type too.You can have Rules components without any parameters as well.Not mentioned in this screencast but still good to know: Bonus: If you add an entry to a multiple-value field in an entity, Rules won’t pick up that the entity has changed – make sure to add a “save entity” action in the rule.Or cloning existing nodes with changes specified in parameters. (Both examples shown in this screencast.) You could also use it for, say, sending customized messages or something. You could, for example, use this for changing comment settings on nodes, or adding selected tags to nodes.It is probably better to target the Rules data widget than doing a standard form_alter, but both will work. You can, by coding, change the form elements used for input.If you have complex parameters – such as taxonomy terms instead of just an integer – you can (mostly) use entity ID in the direct input mode.(If you want to use data from the processed item, you could actually do this inside the Rules component!) This is an issue being worked on. Sadly, you can’t access data from the view item being actioned – you’ll have to stick with fixed input values.Any additional parameters will be displayed as action configuration, meaning that the person executing the VBO gets to choose parameter value.If you have more than one parameter for a Rules component, you can still use it with VBO.This screencast shows “how you can use multiple-parameter Rules components in VBO and get the additional parameters as action configuration,” which translates to: Rules Bonus Pack shows some experimental functionality that can be used with Rules, expanding your way of thinking about and using Rules – not least by utilizing Rules components from other modules.

Rules and Views Bulk Operations presents some of the improved integration between two awesome modules.

Rules Scheduler shows how to schedule evaluation of Rules actions (and other components), and also how to create repeated events.Developing with Rules covers things like exporting Rules configuration and debugging Rules.Basic examples of Rules configuration, presenting some practical use-cases for the Rules module (using only the basic concepts).Basic Rules concepts, such as reaction rules, data types, data input methods, using lists and creating loops, and Rules components.Here's an overview of what will be covered by this series:

This series on Learning the Rules framework was produced by Johan Falk of, and it will present some basic and advanced usage of the Rules framework. Rules allows you to configure different events that will be executed whenever certain conditions are met. The Rules module allows site administrators to define a series of conditionally executed actions on their website through a user interface.
