1. In our
modelfolder, which is under thevideosharedirectory, let's create a new component namedComment.cfcand add the following code to define it:component persistent="true" { property name="id" fieldtype="id" ormtype="int" generator="increment"; property name="comment"; property name="postedAt" ormtype="timestamp"; property name="User" fieldtype="many-to-one" cfc="User" fkColumn="User_Id"; property name="Video" fieldtype="many-to-one" cfc="Video" fkColumn="Video_Id"; }2. In the previous code, we have defined a comment as having an
id, acommentproperty, and the date it was posted. We have also defined its relationships to the other model objects in our application. A user can have many comments; therefore, many comments can belong to one user. The same goes for a video; a video can have many comments, but a comment can only belong to one user. We define these relationships easily using thefieldtype="many-to-one".
