Editing an entity using the JHipster entity sub-generator

While looking through the generated entity screens, we might realize that there are some minor issues that affect the user experience. For example, on the product screens we have a relationship to a product category but when choosing the product category from the drop-down menu during creation, or when showing the category in the list, we show the category by its ID, which is not user-friendly. It would be nice if we could show the product category name instead. This is the default JHipster behavior but it can be customized while defining the relationships. Let's see how we can make our generated screens more user-friendly by editing the JDL model. This will overwrite existing files, but since we are using git we can easily cherry-pick the changes we made, we will see how this is done in a moment. 

In our JDL, we defined relationships between entities using the following code:

relationship OneToOne {
    Customer{user} to User
}

relationship...
