Here is an example of how to design Grails domain class with Intellij Idea.For this we need to have blank domain classes. So lets say we created\u00a0\u00a0three Domain Classes \tCompany,Book,Author<\/p>\n

    \n
  1. To see relationship diagram, Selected Domain Class, and \tselected tab Domain Class Dependencies.It should look like this\n<\/li>\n
  2. Lets assume the relation that publication has many books. So I drag mouse from Company to Books. \tWhich invokes a popup asking about relationship between the domains \tand type and name of the field.\n<\/li>\n
  3. On Selecting ok from previous \tpopup. Their relation is defined in domain and in diagram.\u00a0Similarly, lets define<\/li>\n
      \n
    1. Book hasMany Authors,<\/li>\n
    2. Authors hasMany Books,<\/li>\n
    3. Book belongsTo Author<\/li>\n
    4. And Diagram looked like this.<\/li>\n<\/ol>\n<\/li>\n
    5. Next Step \u2013 Lets add fields to Domain Class all by Intellij Idea’s UI. Select package of domain class and pressshft+ctrl+alt+u. It’ll open package diagram of app.\n<\/li>\n
    6. Now lets add field name to domain \tAuthor. For that we’ll need to select domain author,right click and select fields. It’ll \tinvoke a popup asking details about field.\n

      Similarly we add field name to Author and published on to Book.<\/li>\n

    7. Now lets add a method to named \u201cpublishedBefore\u201d to Book which takes a date and return list of books published before that date.For this we need to right click on domain and select method.And it’ll invoke popup asking \tdetails.Select create and its done.\n<\/li>\n<\/ol>\n

      This was a simple and easy way to create structure of grails app in Intellij Idea.<\/p>\n","protected":false},"excerpt":{"rendered":"
