./gradlew runCommand -Pargs="generate-views org.bookstore.Book"Grails generate-views Command
Purpose
The purpose of the generate-views command in Grails is to generate GSP (Groovy Server Pages) views for a specified domain class.
Examples
Here are some usage examples of the generate-views command:
-
Generate GSP views for a specific domain class, such as
org.bookstore.Book, using Gradle’srunCommand: -
Generate GSP views for all domain classes using a wildcard (
*), again using Gradle’srunCommand:./gradlew runCommand -Pargs="generate-views *" -
Generate GSP views interactively, allowing the user to specify the domain class name, with Gradle’s
runCommand:./gradlew runCommand -Pargs="generate-views"
Description
Grails incorporates a feature known as static scaffolding, simplifying the creation of a CRUD (Create/Read/Update/Delete) interface for a given domain class. This interface usually includes GSP views for listing, displaying details, creating, and editing records. However, it’s important to note that once these views are generated, they do not automatically update when changes are made to the underlying domain class.
The generate-views command addresses this issue by generating only the necessary GSP views required to implement CRUD functionality for the specified domain class. You can provide the domain class name as an argument. If you omit the argument, the command will interactively prompt you to enter the name of the domain class you want to scaffold.
For instance, if your domain class is org.bookstore.Book, executing the generate-views command will create the following views:
-
List View: Displays a list of records.
-
Show View: Displays the details of a single record.
-
Create View: Provides a form for creating new records.
-
Edit View: Provides a form for editing existing records.
These views will be generated in the appropriate directory within your Grails project.
Usage:
./gradlew runCommand -Pargs="generate-views <<domain class name>>"Arguments
The generate-views command accepts the following argument:
-
domain class name- Specifies the name of the domain class for which you want to generate the GSP views. This argument is case-sensitive. Additionally, you can use a wildcard (*) as the argument to generate views for all domain classes within your Grails application.
By utilizing the generate-views command, Grails developers can efficiently create GSP views tailored to specific domain classes or generate them for all classes within their application. This facilitates the presentation and interaction with data through a web interface while allowing for customization of views as needed.
