![]() Although the message is defined, you still need to visualize it.Click OK to confirm the change and go back to diagram. You should see the message added appear in the drop-down menu of Mesasge.Name the message in the Message specification and click OK to confirm.Click on the drop down menu of Message and select Create Message (Business Process) from the pop-up menu.Right click on the message flow that you want to model its message and select Open Specification… from the pop-up menu.You can define a message that passes by message flow and visualize it. Modeling and visualizing message pass by message flow If you really want to keep the invalid connector, choose Ignore all at the bottom of dialog box. If the connector should not be there, you may select to delete it. First, you can correct your invalid flow by changing its type, like to change from message to sequence flow. There are several actions you can perform. If you attempt to use a type of flow incorrectly, like to connect flow objects within participant with message flow, you will be prompt to correct your flow. Correcting invalid flowĪs mentioned before, you can use sequence flow to connect flow objects within a participant and use message flow to connect flow objects in separate participants. You cannot use message flow to connect flow objects within the same participant. Message flow is used to show the flow of messages between separate pools/lanes. A BPMN sequence flow is used to connect flow objects in a process or a choreography to show the flow. The whenLoaded method may be used to conditionally load a relationship.In business process modeling, there are two types of connectors for modeling flows in a process in a business process diagram – Sequence flow and Message flow. Ultimately, this makes it easier to avoid "N+1" query problems within your resources. This allows your controller to decide which relationships should be loaded on the model and your resource can easily include them only when they have actually been loaded. In addition to conditionally loading attributes, you may conditionally include relationships on your resource responses based on if the relationship has already been loaded on the model. Furthermore, it should not be used within arrays with numeric keys that are not ordered sequentially. The mergeWhen method should not be used within arrays that mix string and numeric keys. Resources extend the Illuminate\Http\Resources\Json\JsonResource class:Īgain, if the given condition is false, these attributes will be removed from the resource response before it is sent to the client. By default, resources will be placed in the app/Http/Resources directory of your application. To generate a resource class, you may use the make:resource Artisan command. Of course, you may always convert Eloquent models or collections to JSON using their toJson methods however, Eloquent resources provide more granular and robust control over the JSON serialization of your models and their relationships. Eloquent's resource classes allow you to expressively and easily transform your models and model collections into JSON. For example, you may wish to display certain attributes for a subset of users and not others, or you may wish to always include certain relationships in the JSON representation of your models. When building an API, you may need a transformation layer that sits between your Eloquent models and the JSON responses that are actually returned to your application's users. ![]()
