generating a 'created date' field for web content

bjornl — Mon, 04 Jun 2007 19:32:58 GMT

Hi,I need to be able to produce listings of web content sorted on date, so it would be very useful to have the creation time of the generated xml file as a field in that generated file, like so;<mytype> <createdDate>2007-06-04</createdDate> <anothernode /></mytype>‍‍‍‍‍

Bjorn:

You can add a callout to your web form to generate the date field, and then return that as a read-only field.

Here's an example of how read-only fields (fixed fields) can be specified in your XSD. This works for both elements and attributes. Note that difference between default and fixed values, where default is a pre-set modifiable value populated at form instantiation, and where fixed is returned read-only:

<xs:element name="elements">
          <xs:complexType>
            <xs:sequence>
              <xs:element name="fixed_string" type="xs:normalizedString" fixed="fixed string element value"/>
              <xs:element name="default_string" type="xs:normalizedString" default="default string element value"/>
              <xs:element name="fixed_integer" type="xs:integer" fixed="3"/>
              <xs:element name="default_integer" type="xs:integer" default="3"/>
              <xs:element name="fixed_date" type="xs:date" fixed="1978-08-08"/>
              <xs:element name="default_date" type="xs:date" default="1978-08-08"/>
              <xs:element name="fixed_time" type="xs:time" fixed="14:45:00"/>
              <xs:element name="default_time" type="xs:time" default="14:45:00"/>
              <xs:element name="fixed_radio" type="five_string_values" fixed="three">
                <xs:annotation><xs:appinfo><alf:appearance>full</alf:appearance></xs:appinfo></xs:annotation>
              </xs:element>
              <xs:element name="default_radio" type="five_string_values" default="three">
                <xs:annotation><xs:appinfo><alf:appearance>full</alf:appearance></xs:appinfo></xs:annotation>
              </xs:element>
              <xs:element name="fixed_combobox" type="five_string_values" fixed="three">
                <xs:annotation><xs:appinfo><alf:appearance>minimal</alf:appearance></xs:appinfo></xs:annotation>
              </xs:element>
              <xs:element name="default_combobox" type="five_string_values" default="three">
                <xs:annotation><xs:appinfo><alf:appearance>minimal</alf:appearance></xs:appinfo></xs:annotation>
              </xs:element>
              <xs:element name="fixed_textarea" type="xs:string" fixed="fixed string value"/>
              <xs:element name="default_textarea" type="xs:string" default="default string value"/>
              <xs:element name="fixed_checkbox" type="xs:boolean" fixed="true"/>
              <xs:element name="default_checkbox" type="xs:boolean" default="true"/>
            </xs:sequence>
          </xs:complexType>
        </xs:element>

Yeah I get the simple part, the fixed attribute. But what do you mean by "making a callout to my webform"? Could you give an example?

Bjorn:

You can use an xs:include in your schema to reference a JSP contained within your web project to dynamically construct portions of the schema prior to our generating the XForm and rendering HTML form for the end-user to fill out. You reference the JSP as follows in your schema:


  <xs:include schemaLocation="/media/releases/get_company_footer_choices_simple_type.jsp"/>
‍‍‍

Note that the JSP page must be contained within your web project (if the form is subscribed to by a web project not having that JSP, it will not work. We do plan on supporting centralized callouts in the data dictionary at a future point in time.

The implementation in the JSP you can find here:


<jsp:root version="1.2"
          xmlns:jsp="http://java.sun.com/JSP/Page"
      xmlns:c="http://java.sun.com/jsp/jstl/core"
     xmlns:pr="http://www.alfresco.org/alfresco/pr">   
  <!– xmlns:pr is mapped to /WEB-INF/pr.tld by web.xml –>
  <jsp:directive.page language="java" contentType="text/html; charset=UTF-8"/>
  <jsp:directive.page isELIgnored="false"/>

  <!–
  The expected output is in the form:
  <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" 
             xmlns:alfresco="http://www.alfresco.org/alfresco"
        elementFormDefault="qualified">
    <xs:simpleType name="company_footer_choices">
      <xs:restriction base="xs:string">
        <xs:enumeration value="company_footer_1.xml">
     <xs:annotation>
       <xs:appinfo>
         <alfresco:label>Company Footer 1 Name</alfresco:label>
       </xs:appinfo>
     </xs:annotation>
        </xs:enumeration>
        <xs:enumeration value="company_footer_2.xml">
     <xs:annotation>
       <xs:appinfo>
         <alfresco:label>Company Footer 2 Name</alfresco:label>
       </xs:appinfo>
     </xs:annotation>
        </xs:enumeration>
      </xs:restriction>
    </xs:simpleType>
  </xs:schema>
  –>
  <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" 
             xmlns:alf="http://www.alfresco.org"
          elementFormDefault="qualified">
    <xs:simpleType name="company_footer_choices">
      <xs:restriction base="xs:normalizedString">
   <!– call into CompanyFooterBean to retrieve all company footers –>
        <c:forEach items="${pr:getCompanyFooterChoices(pageContext)}" var="companyFooter">
          <jsp:element name="xs:enumeration">
       <!– this is the file name of the company footer –>
       <jsp:attribute name="value"><c:out value="${companyFooter.fileName}"/></jsp:attribute>
            <jsp:body>
           <xs:annotation>
           <xs:appinfo>
        <!– this produces the label displayed in the combobox within the press release form –>
                  <alf:label><c:out value="${companyFooter.name}"/></alf:label>
      </xs:appinfo>
              </xs:annotation>
            </jsp:body>
     </jsp:element>
        </c:forEach>
      </xs:restriction>
    </xs:simpleType>
  </xs:schema>
</jsp:root>
