1 USE OF EXPANDO API IN LIFERAYS By Akaram siddiqui

2 Expando Api In Liferay the Expando service is a "generic" service which allows you to dynamically define a collection of data. The mechanism is supported by using four database tables: ExpandoTable, ExpandoColumn, ExpandoRow and ExpandoValue. This data can be 1) typed ( Date, double, long, short, String, and arrays etc) 2) associated with a specific entity (e.g. com.liferay.portal.model.group') 3) arranged into any number of "columns" 1. Create table. Below line code allow you to create the dynamically table. com.liferay.portlet.expando.service.expandotablelocalserviceutil. And if you want to create new table then use bellow code.. ExpandoTable table = ExpandoTableLocalServiceUtil.addTable(< companyid>, <classname>, <tablename>); Here.. 1. companyid type will be long and you can get companyid by bwlow method. long yourcompanyid = CompanyLocalServiceUtil.getCompanies().get(0).getCompanyId();

3 2. classname will be String 3. tablename type should be String If you want to create new column then use bellow code.. ExpandoColumn column = ExpandoColumnLocalServiceUtil.addColumn(<tableId>, <columnname>, <type>); 1. tableid type:long 2. columnname type:string 3. type should be int. If you want to create new row then use bellow code.. ExpandoRow row = ExpandoRowLocalServiceUtil.addRow(<tableId>, <classpk>); 1. tableid type:long 2. classpk type:long The above code will add new row in ExpandoRow table. 2. Store data or values in table The class below are use to store value in expandovalue table com.liferay.portlet.expando.service.expandovaluelocalserviceutil ExpandoValue values = ExpandoValueLocalServiceUtil.addValue(<classNameId>,

4 <tableid>, <columnid>, <classpk>, <value>); 1. classnameid type: long 2. tableid type: long 3. columned type: long 4. classpk type: long 5. value type: String 3. Delete data If you want to delete Table then use below method. ExpandoTableLocalServiceUtil.deleteTable(long <tableid>) If you wanr to delete Column then use below method. ExpandoColumnLocalServiceUtil.deleteColumn(long < olumned>) If you want to delete Row then use below method. ExpandoRowLocalServiceUtil.deleteRow(long <rowid>) If you want to dealete value then use below method ExpandoValueLocalServiceUtil.deleteValue(long<valueId>) 4. Update data If you want to update Table then use.. ExpandoTableLocalServiceUtil.updateTable(long <tableid>, String <name>) ExpandoTableLocalServiceUtil.updateExpandoTable(ExpandoTable <table>) If you want to update Row then use below method

5 ExpandoValueLocalServiceUtil.updateExpandoValue(<rowId>) 5. Search Data ss If you want to Search for Table then below method. ExpandoTableLocalServiceUtil.getExpandoTable(long <tableid>) If you want to Search for Column then below method ExpandoColumnLocalServiceUtil.getExpandoColumn(long <columnid>) If you want to Search for Row then use below method. ExpandoRowLocalServiceUtil.getExpandoRow(long <rowid>) If you want to search value then use below method. ExpandoValueLocalServiceUtil.getExpandoValue(long <valueid>)

6 As we mentioned above now we will use that all api. Here we will add date custom attribute in create_account.jsp and we will insert this date indo expand table using expand api and then we will search data using expand search API.. Using Custom Attribute tags to display editable or non-editable values Using the <liferay-ui:custom-attribute-list /> jsp tag 4) This tag generates a list of all the (non-hidden, and VIEWable) tags for a given entity type and instance 5) The available parameters are: 1. classname, the fully qualified name of the entity (required = true) e.g. com.liferay.portal.model.user 2. classpk, the primarykey of the entity instance (or zero (0) if there is not currently an instance) (required = true) 3. editable, is this invocation to check UPDATE permission and show as a input field if check returns true (required = false, default = false) 4. label, is the label of the field rendered, if not simply show the raw output of the attribute value (required = false, default = false) 6) A sample invocation looks like: Note : Add these code in create account.jsp page Billow </aui:fieldset> <liferay-ui:custom-attribute-list classname="com.liferay.portal.model.user" classpk="<%= 01 %>"

7 editable="<%= true %>" label="<%= true %>" /> Now go to the create_account.jsp page throw liferay login there you will see your custom attribute field which you have added through control panel Note : here am adding date time picker for new user joining and later we will search user throw this joining date. In sort Step to add custom attribute in create_account.jsp page Step.1 login to liferay =>go to the control panel =>go to the portal=>click on custom field =>click on user then click on add custom field and fill in billow key user_joining and in Type select Date click on save button Now click on action button right side and give permission for guest tick on update and view check box. Step.2 coppy create_account.jsp from source folder of your liferay and using hook

8 customize the page means put the following code billow the </aui:fieldset> the code is : <liferay-ui:custom-attribute-list classname="com.liferay.portal.model.user" classpk="<%= 01 %>" editable="<%= true %>" label="<%= true %>" /> now ant build your create_account.jsp page and go to the create_account page through liferay login page refresh your page you will see your custom attribute field. Step :3 now create new user account throw create_account.jsp page.sellect your joining date. Note : this joining date will save in Expandovalue table in your data base Step :4 now write code on your view.jsp page for fatching and displaying recard of same joining date for user the code is :
