Encrypted Passwords in Liferay

Basically when you create a user programmatically we may face issue in password creation.

To avoid that its always better to go with the default APIs of liferay.

For Ex:

UserLocalServiceUtil.addUser(creatorUserId, companyId, autoPassword, password1, password2, autoScreenName, screenName, emailAddress, facebookId, openId, locale, firstName, middleName, lastName, prefixId, suffixId, male, birthdayMonth, birthdayDay, birthdayYear, jobTitle, groupIds, organizationIds, roleIds, userGroupIds, sendEmail, serviceContext);


But you may come across some place where you may need to use

UserLocalServiceUtil.addUser(user);

So at that time We need to encrypt the plain text password

So we can use Liferay's PasswordEncryptorUtil to encrypt our plain text.

user.setPassword(PasswordEncryptorUtil.encrypt("test"));
user.setPasswordUnencrypted("test");
user.setPasswordEncrypted(true);

UserLocalServiceUtil.addUser(user);

Even we can use

PasswordEncryptorUtil.encrypt(algorithm, plainTextPassword, encryptedPassword);

to select the algorithm.

         UserLocalServiceUtil.addRoleUser(role.getRoleId(), user.getUserId());

Upload data and store in database

CSV files can be used to do bulk import. 

Open CSV:
It is a very simple csv (comma-separated values) parser library for Java. It was developed because all of current csv parsers I've come across don't have commercial-friendly licenses.  


Download Open CSV jar file from OpenCSV

Add jar to your portlet

Just write file tag in your jsp page
  
<aui:form action="<%=BulkImportURL.toString()%>" method="post" name="fm" enctype="multipart/form-data">
<aui:input name="QuestionAnswerAttach" id="QuestionAnswerAttach" type="file" label="Upload your Question Answer key"></aui:input>
<aui:button type="submit" value="Upload Questions"/>
</aui:form>

Then in your action class

Inside your method write

    UploadPortletRequest uploadPortletRequest = PortalUtil.getUploadPortletRequest(actionRequest);
        java.io.File document = uploadPortletRequest.getFile("QuestionAnswerAttach");
        CSVReader readers = new CSVReader(new FileReader(document));
        List<String[]> myEntries = readers.readAll();
for(int i=0;i<myEntries.size();i++){
String[] s = myEntries.get(i);
System.out.println(s[0]);  

}

And you can store the value in database.

Liferay autofields

Use the following code in your jsp page

<div id="link-fields">
                <div class="lfr-form-row lfr-form-row-inline">
                    <div class="row-fields">
                        <aui:input fieldParam='linkNumber0' id='linkNumber0' name="linkNumber0" label="Links" />
                    </div>
                </div>
            </div>
<aui:script use="liferay-auto-fields">
 new Liferay.AutoFields(
       {
           contentBox: '#link-fields',
           fieldIndexes: '<portlet:namespace />linksIndexes'
       }
   ).render();
</aui:script>



Use this in your action method

    String linksIndexesString = actionRequest.getParameter(
                "linksIndexes");
        System.out.println("=============linksIndexesString=="+linksIndexesString);
            int[] linksIndexes = StringUtil.split(linksIndexesString, 0);
            for (int linksIndex : linksIndexes) {
                String number = ParamUtil.getString(actionRequest, "linkNumber" + linksIndex);
                System.out.println("=============linkNumber=="+number);
                

            }

Create a custom theme,

And In
templates/navigation.vm 

Remove the below line

#set ($nav_item_link_css_class="dropdown-toggle")

Then parent page will be clickable and you can navigate.

Exporting data into csv format

Use Open CSV to export the data.

Here I have given download option for the whole table.

I am getting the whole table data as a list.And making csv values and storing in csv file.

public void exportEvent(ActionRequest actionRequest,ActionResponse actionResponse) throws SystemException, IOException{
       List<stuadmission> admissions = stuadmissionLocalServiceUtil.getstuadmissions(-1, -1);

             
    CSVWriter writer = new CSVWriter(new FileWriter("/home/filename.csv"), '\t');
    for (stuadmission student : admissions){
            String str = Integer.toString(student.getAdmissionno());
           String str2 = str + ","+ student.getBatch();
           
            String[] strings = str2.split(",");
            writer.writeNext(strings);
                   writer.close();}

Including structure form in our custom portlet

Step 1: Create a structure in portal.

To know how to create structure :
http://liferayplanet.blogspot.in/2015/01/structure-and-template-in-liferay-62.html

Step 2: Then in your jsp page

long structureId= 12345;
ServiceContext serviceContext = ServiceContextFactory.getInstance(request);
DDMStructure ddm = null;
ddm = DDMStructureLocalServiceUtil.getDDMStructure(structureId);
Fields newFields = DDMUtil.getFields(
ddm.getStructureId(), serviceContext);

 Here we get ddmstructure and we will use DDMUtil.getFields to get all the form fields.

Step 3:Then use the below tag
<%@ taglib uri="http://liferay.com/tld/ddm" prefix="liferay-ddm"%>
<liferay-ddm:html
classNameId="<%= PortalUtil.getClassNameId(DDMStructure.class)%>"
classPK="<%= ddm.getStructureId() %>"
fields="<%= newFields %>"
/>

Step 4:Then to get in controller use

               ServiceContext serviceContext;
DDMStructure ddmStructure = null;

serviceContext = ServiceContextFactory.getInstance(
JournalArticle.class.getName(), actionRequest);
Object[] contentAndImages = null;

ddmStructure = DDMStructureLocalServiceUtil
.getDDMStructure(structureId);
Locale locale = LocaleUtil.getDefault();

contentAndImages =  getContentAndImages(
ddmStructure, locale, serviceContext);
content = (String) contentAndImages[0];

            public static Object[] getContentAndImages(
DDMStructure ddmStructure, Locale locale,
ServiceContext serviceContext)
throws Exception {

Fields fields = DDMUtil.getFields(
ddmStructure.getStructureId(), serviceContext);


Map<String, byte[]> images = getImages(fields, locale);

return new Object[] {
JournalConverterUtil.getContent(ddmStructure, fields), images
};
}
protected static Map<String, byte[]> getImages(Fields fields, Locale locale)
throws Exception {

Map<String, byte[]> images = new HashMap<String, byte[]>();

for (Field field : fields) {
String dataType = field.getDataType();

if (!dataType.equals(FieldConstants.IMAGE)) {
continue;
}

List<Serializable> values = field.getValues(locale);

for (int i = 0; i < values.size(); i++) {
String content = (String)values.get(i);

if (content.equals("update")) {
continue;
}

StringBundler sb = new StringBundler(6);

sb.append(StringPool.UNDERLINE);
sb.append(field.getName());
sb.append(StringPool.UNDERLINE);
sb.append(i);
sb.append(StringPool.UNDERLINE);
sb.append(LanguageUtil.getLanguageId(locale));

images.put(sb.toString(), UnicodeFormatter.hexToBytes(content));
}
}

return images;
}

Create Journal Article Programmatically

We can create journal article programmatically by using add article method

JournalArticleLocalServiceUtil.addArticle (10198, 10181, 0, nameMap, nameMap,content, "23303",ddmTemplate.getTemplateKey(), serviceContext);

To create the title map and description map use localizationutil

Creating titlemap:

String mycustomwebcontent = "New title";

Map<Locale,String> nameMap = LocalizationUtil.getLocalizationMap(mycustomwebcontent);

In template key and structure key pass your structure and template key.

And use servicecontext object

ServiceContext serviceContext = ServiceContextFactory.getInstance(request);

Plugins Configuration - Deactivate unwanted Portlets,Themes and Layout Plugins

We may have many unwanted plugins

For Ex:
Portlet plugins : loan calculator,dictionary etc.
Theme plugins : themes which we are not using in our project

So we can deactivate/activate the plugins as we need.

Step 1: Go to control panel

Step 2: You can see plugins configuration under apps.Click on plugins configuration

Step 3: You will be seeing three tabs like Portlet plugins,theme plugins and layout plugins

Step 4: So you will be seeing all default plugins and also our custom developed plugins.

Step 5: Just click on the plugin open and uncheck the active checkbox and save it.
