42.18 Using Bootstrap Library using Functions
The next example uses the Bootstrap JavaScript Library when generating the HTML page.

Load "weblib.ring"

new BootstrapPage {
divstart([ :class = "container" ])
divstart([ :class = "jumbotron" ])
h1("Bootstrap Page")
divend()

Instead of using functions to generate the HTML elements, we will use objects.

42.20 CRUD Example using MVC
The next example uses the weblib.ring & datalib.ring.
The datalib.ring contains classes for creating database applications using MVC pattern.
In this example we create an object from the SalaryController class then call the Routing method.
We deﬁne the website variable to contains the basic url of the page.
When we create the SalaryModel class from the ModelBase class, the salary table will be opened and the columns
data will be deﬁned as attributes in the model class.
The SalaryView class create an object from the SalaryLanguageEnglish class to be used for translation.
The method AddFuncScript is used to call the form for adding/modifying record data.
The method FormViewContent is used to determine the controls in the form when we add or modify a record.
Load "weblib.ring"
Load "datalib.ring"
Import System.Web
website = "ex24.ring"
New SalaryController { Routing() }
42.20. CRUD Example using MVC 305

Class SalaryModel from ModelBase
Class SalaryController From ControllerBase
Class SalaryView From ViewBase
oLanguage = new SalaryLanguageEnglish
Func AddFuncScript oPage,oController
return oPage.scriptfuncajax("myadd",oController.cMainURL+
oController.cOperation+"=add","mysubpage")
Func FormViewContent oController,oTranslation,oPage
return [
[ oTranslation.aColumnsTitles[2], "textbox", "name",
oController.oModel.Name, oPage.stylewidth("100%") ],
[ oTranslation.aColumnsTitles[3], "textbox", "salary",
oController.oModel.Salary, oPage.stylewidth("50%") ]
]
Class SalaryLanguageEnglish
cTitle = "Salary Table"
cBack = "back"
aColumnsTitles = ["ID","Name","Salary"]
cOptions = "Options"
cSearch = "Search"
comboitems = ["Select Option...","Edit","Delete"]
cAddRecord = "Add Record"
cEditRecord = "Edit Record"
cRecordDeleted = "Record Deleted!"
aMovePages = ["First","Prev","Next","Last"]
cPage = "Page"
cOf = "of"
cRecordsCount = "Records Count"
cSave = "Save"
temp = new page
cTextAlign = temp.StyleTextRight()
cNoRecords = "No records!"

42.21 Users registration and Login
We have the users classes (Model, View & Controller) to deal with the users data like username & email.
The next code is stored in ex25_users.ring
Class UsersModel from ModelBase
cSearchColumn = "username"
Class UsersController From ControllerBase
