Now the cars know their owner, but not the opposite. This is an example of such an association:Īs showed previously, the equivalent of a One-to-Many relationship is a Many-to-One: Unidirectional relationships for One-to-Many relationships are not (yet) supported by JHipster (see this page for more information about this). In this bidirectional relationship, an Owner can have many cars, and a Car can have only one owner. Notice that in order to achieve a unidirectional relationship we removed the citizen label so that Passport doesn’t have it. If you’re looking for a unidirectional relationship: Here, we have a bidirectional one-to-one relationship between Driver and Car, with Driver as the owner of the relationship. Please note that we only support the relationships listed in the Managing relationships page. We use the examples from JHipster in order to show how to do it with an editor. Note that you don’t need to capitalize type names ( except for composed names like BigDecimal, JHipster-UML capitalizes names). We have the attributes publicationDate and price set with the types BigDecimal and LocalDate we created as DataType. Here is an example of a properly created class for JHipster. You can look at the tables with all the types supported by JHipster and the validations you can use for each here. To have JHipster supported types like “BigDecimal”, “LocalDate”…, you can create a PrimitiveType or a DataType for it. An attribute must have a type supported by JHipster, otherwise it won’t work. The class diagram should modelize the entities of your JHipster application domain, thus you have restrictions, you have to follow the methodology.Įach entity is represented by a class, its fields are the class’ attributes. To use JHipster-UML, you need a class diagram exported in XMI and JHipster-UML will parse it to create your entities. Otherwise, using v2.0.0+ is the choice for v3.0.0+ of the generator. If you’re using the generator before v3.0.0, then you must use JHipster UML v1.6.5 (latest patch release). JHipster UML is a tool that can be used with the JHipster’s generator. Git clone :jhipster/jhipster-uml.git for SSH If you want the ‘bleeding edge’ (almost perfectly safe to use) version, you can clone our git repo from our GitHub project: You might want to use Powershell or another shell when using JHipster UML (or JHipster). The JHipster generator’s questions (from InquirerJS) could not work (the user is stuck when answering the questions). The link provides a solution to fix that if such a thing happens.įinally, an issue has been reported from a Windows user using Git Bash. This link may help if you encounter an issue on Windows.Īnother issue that can be encountered on Windows is this one. Please note that using JHipster-UML (or JHipster) might be troublesome (one has to install some tools to really be able to use the Node environment without any issue).
