Removing Friends
A community user may desire to remove someone from his friend list. This can be easily implemented through the following Struts action and JSP template:
<form-bean name="friendshipForm" type="com.ndc.community.struts.actions.forms.FriendshipForm"/> <action path="/friendship/resign" name="friendshipForm" scope="request" type="com.ndc.community.struts.actions.friendship.ResignFriendship"> <forward name="error" path="/" /> <forward name="success" path="/" redirect="true" /> </action>
An example JSP template can be as follows:
<html:form action="/friendship/resign"> <community:user id="currentUser"/> <community:user id="targetUser" userId="${param.userId}"/> <html:hidden property="userId" value="${currentUser.id}"/> <html:hidden property="friendId" value="${targetUser.id}"/> <html:submit value="Remove"/> </html:form>
It may be desirable that the removed person does not get any notification of removal. A different Struts Action can be used to achieve this feature.
<form-bean name="friendshipForm" type="com.ndc.community.struts.actions.forms.FriendshipForm"/> <action path="/friendship/remove" name="friendshipForm" scope="request" type="com.ndc.community.struts.actions.friendship.RemoveFriendship"> <forward name="error" path="/" /> <forward name="success" path="/" redirect="true" /> </action>
The action expects the same set of form properties and thus, the same JSP template can be used with the name of the action.
<html:form action="/friendship/remove"> <community:user id="currentUser"/> <community:user id="targetUser" userId="${param.userId}"/> <html:hidden property="userId" value="${currentUser.id}"/> <html:hidden property="friendId" value="${targetUser.id}"/> <html:submit value="Remove"/> </html:form>
