New model from scratch

This page describes how to create a new Telosys model from scratch.

Create a new model

To create a new model use the nm ("New Model") command

Example :

nm cars will create the "cars" model

Use the lm (List Models) command to see all models defined in the current project

When a new model has been created it is set as the "current model"

Example :

telosys#(cars.model)>lm
1 model(s) :
 . cars.model
 
telosys#(cars.model)>nm mymodel
Model 'mymodel' created (mymodel.model), current model is now 'mymodel'

telosys#(mymodel.model)>lm
2 model(s) :
 . cars.model
 . mymodel.model

Create an entity in the current model

The le (List Entities) command can be used to see all the entities of the current model

Obviously, at the beginning there's no entity.

To create an entity use the ne (New Entity) command

Examples :

ne Car will create the "Car" entity in the "cars" model

ne Driver will create the "Driver" entity in the "cars" model

Example :

telosys#(cars.model)>le
 . Brand (table 'Brand')
 . Car (table 'Car')
 . Company (table 'Company')
 . Driver (table 'Driver')

telosys#(cars.model)>ne Foo
Entity 'Foo' created.

Edit an entity

To define an entity you must define all its attributes, for that use the ee (Edit Entity) command.

Example :

ee Driver will launch the external editor to edit the "Driver.entity" file.

Telosys cannot launch an external editor if your Operating System doesn't have a GUI, for example a Linux server without GUI. In this case you will have to edit the ".entity" files outside in a separated console.

Delete an entity

To delete an entity in the current model use the "de" (Delete Entity) command.

Examples :

de Driver will delete the "Driver" entity

telosys#(cars.model)>de Foo
Entity 'Foo' deleted.

Delete a model

To delete a model use the "dm" (Delete Model) command.

Example :

dm cars will delete the "cars" model
