Web Section plugin module

Purpose of this Module Type

Web Section plugin modules allow plugins to define new sections in application menus. Each section can contain one or more links. To insert the links themselves, see the Web Item Plugin Module.

Configuration

The root element for the Web Section plugin module is web-section It allows the following attributes and child elements for configuration:

Attributes

1
2
<component-import
key="appProps"
interface="com.atlassian.sal.api.ApplicationProperties"/>

*key, location, weight attributes are required.

Elements

The table summarises the elements. The sections below contain further information.

*label element is required.

Label

Label elements may contain optional parameters, as shown below:

1
2
<label key="common.concepts.create.new.issue">
    <param name="param0">$helper.project.name</param>
</label>

• The parameters allow you to insert values into the label using Java's MessageFormat syntax.
• Parameter names must start with param and will be mapped in alphabetical order to the substitutions in the format string. I.e. param0 is {0}, param1 is {1}, param2 is {2}, etc.
• Parameter values are rendered using Velocity, allowing you to include dynamic content.

Tooltip 

Tooltip elements have the same attributes and parameters as the label elements. See above.

Param

Param elements represent a map of key/value pairs, where each entry corresponds to the param elements attribute: name and value respectively.

1
2
<param name="key" value="value" />

The value can be retrieved from within the Velocity view with the following code, where $item is a WebItemModuleDescriptor:

1
2
$item.webParams.get("key") <!-- retrieve the value -->
$item.webParams.getRenderedParam("key", $user, $helper) <!-- retrieve the Velocity rendered value -->

If the value attribute is not specified, the value will be set to the body of the element. I.e. the following two param elements are equivalent:

1
2
<param name="isPopupLink" value="true" />
<param name="isPopupLink">true</param>

Context-provider

The context-provider element must contain a class attribute with the fully-qualified name of a Java class. The referenced class:The context-provider element adds to the Velocity context available to the web section and web item modules. You can add what you need to the context, to build more flexible section and item elements. Currently only one context-provider can be specified per module. Additional context-providers are ignored.

• must implement com.atlassian.plugin.web.ContextProvider, and
• will be auto-wired by Spring before any additions to the Velocity context.

For example, the following context-provider will add historyWindowHeight and filtersWindowHeight to the context.

In the following example, HeightContextProvider extends AbstractJiraContextProvider, which is only available in JIRA and happens to implement ContextProvider. The AbstractJiraContextProvider conveniently extracts the User and JiraHelper from the context map, which you would otherwise have to do manually.

1
2
public class HeightContextProvider extends AbstractJiraContextProvider
{
    private final ApplicationProperties applicationProperties;

    public HeightContextProvider(ApplicationProperties applicationProperties)
    {
        this.applicationProperties = applicationProperties;
    }

    public Map getContextMap(User user, JiraHelper jiraHelper)
    {
        int historyIssues = 0;
        if (jiraHelper != null && jiraHelper.getRequest() != null)
        {
            UserHistory history = (UserHistory) jiraHelper.getRequest().getSession().getAttribute(SessionKeys.USER_ISSUE_HISTORY);
            if (history != null)
            {
                historyIssues = history.getIssues().size();
            }
        }
        int logoHeight = TextUtils.parseInt(applicationProperties.getDefaultBackedString(APKeys.JIRA_LF_LOGO_HEIGHT));
        String historyHeight = String.valueOf(80 + logoHeight + (25 * historyIssues));
        String filterHeight = String.valueOf(205 + logoHeight);
        return EasyMap.build("historyWindowHeight", historyHeight,
                             "filtersWindowHeight", filterHeight);
    }
}

The above HeightContextProvider can be used by nesting the following element in a web item module.

1
2
<context-provider class="com.atlassian.jira.plugin.web.contextproviders.HeightContextProvider" />

The newly added context entries historyWindowHeight and filtersWindowHeight can be used in the XML module descriptors just like normal velocity context variables, by prefixing them with the dollar symbol ($):

1
2
<!-- pass the value of historyWindowHeight as a parameter called windowHeight (see param element above for its usage) -->
<param name="windowHeight">$historyWindowHeight</param>

<!-- set the link's label to print the value of filtersWindowHeight -->
<label>filter window height is: $filtersWindowHeight</label>

Condition and Conditions elements

Conditions can be added to the web section, web item and web panel modules, to display them only when all the given conditions are true.

Condition elements must contain a class attribute with the fully-qualified name of a Java class. The referenced class:

• must implement com.atlassian.plugin.web.Condition, and
• will be auto-wired by Spring before any condition checks are performed.

Condition elements can take optional parameters. These parameters will be passed in to the condition's init() method as a map of string key/value pairs after autowiring, but before any condition checks are performed. For example:

1
2
<condition class="com.atlassian.jira.plugin.webfragment.conditions.JiraGlobalPermissionCondition">
    <param name="permission">admin</param>
</condition>

NOTE: In versions before JIRA 3.7, this class is called com.atlassian.jira.plugin.web.conditions.JiraGlobalPermissionCondition

To invert a condition, add the attribute 'invert="true"' to the condition element. This is useful where you want to show the section if a certain condition is not satisfied.
Conditions elements are composed of a collection of condition/conditions elements and a type attribute. The type attribute defines what logical operator is used to evaluate its collection of condition elements. The type can be one of AND or OR.

For example: The following condition is true if the current user is a system administrator OR a project administrator:

1
2
<conditions type="OR">
    <condition class="com.atlassian.jira.plugin.webfragment.conditions.JiraGlobalPermissionCondition">
        <param name="permission">admin</param>
    </condition>
    <condition class="com.atlassian.jira.plugin.webfragment.conditions.UserHasVisibleProjectsCondition">
        <param name="permission">project</param>
    </condition>
</conditions>

NOTE: In versions before JIRA 3.7, the second class is called com.atlassian.jira.plugin.web.conditions.UserHasProjectsCondition

Example

Here is an example atlassian-plugin.xml file containing a single web section, using a condition that will be available in JIRA:

1
2
<atlassian-plugin name="Hello World Plugin" key="example.plugin.helloworld" plugins-version="2">
    <plugin-info>
        <description>A basic web section module test</description>
        <vendor name="Atlassian Software Systems" url="http://www.atlassian.com"/>
        <version>1.0</version>
    </plugin-info>

    <web-section key="usersgroups" name="Users and Groups Section" location="system.admin" weight="110">
        <label key="admin.menu.usersandgroups.users.and.groups" />
        <condition class="com.atlassian.jira.plugin.webfragment.conditions.UserIsAdminCondition" />
    </web-section>
</atlassian-plugin>

NOTE: In versions before JIRA 3.7, this class is called com.atlassian.jira.plugin.web.conditions.UserIsAdminCondition
