关于<apex:inputfile>组件上传文件:
a.用Document对象来接：
*需要为document指定一个folderId
Page:
<apex:page controller="PersonalUploadFileController">
<apex:apexMessages />
<apex:form >
<apex:pageBlock >
<apex:inputFile value="{!document.body}" fileName="{!document.name}" />
<apex:commandButton value="Upload" action="{!upload}"/>
</apex:pageBlock>
</apex:form>
</apex:page>
Controller:
public class PersonalUploadFileController{
private Document document = new Document();
public Document getDocument(){
return document;
}
public void setDocument(Document document){
this.document = document;
}
public PersonalUploadFileController(){
//Document document = new Document();
}
public void upload(){
System.debug('name:' + document.name);
document.folderId = UserInfo.getUserId();
try{
insert document;
ApexPages.addMessage(new ApexPages.Message(ApexPages.severity.INFO, 'Upload Success!'));
}catch(Exception e){
ApexPages.addMessage(new ApexPages.Message(ApexPages.severity.INFO, 'Upload Fail!'));
System.debug(e);
}
}
}
b.用Attachment对象来接：
*需要为attach指定一个parentId
Page:
<apex:page controller="PersonalAttachmentController">
<apex:form >
<apex:pageBlock >
<apex:inputFile value="{!attach.Body}" fileName="{!attach.Name}" />
<apex:commandButton value="attach" action="{!attach}"/>
</apex:pageBlock>
</apex:form>
</apex:page>
Controller:
public class PersonalAttachmentController{
private Attachment attach = new Attachment();
public Attachment getAttach(){
return attach;
}
public void setAttach(Attachment attach){
this.attach = attach;
}
public PersonalAttachmentController(){
}
public void attach(){
System.debug(attach.Name);
try{
insert attach;
ApexPages.addMessage(new ApexPages.Message(ApexPages.severity.INFO, 'Upload Success!'));
}catch(Exception e){
System.debug(e);
ApexPages.addMessage(new ApexPages.Message(ApexPages.severity.INFO, 'Upload Fail!'));
}
}
}
c.用content对象来接：
<apex:page>
<apex:pageBlock>
<apex:inputFile fileName="{!content.PathOnClient}" value="{!content.VersionDat a}"/>
<apex:commandButton value="upload" action="{!upload}"/> </apex:pageBlock>
</apex:page>
*content<===>ContentVersion
此对象可以手动创建，VersionData字段，必须指定。PathOnClient字段跟另外一字段二选一指定。
ContentWorkspace 与 ContentWorkspaceDoc

Select Id, IsOwner, CreatedDate, ContentWorkspace.Id, ContentWorkspace.Name From ContentWorkspaceDoc
父类中查子类：
不支持。
ContentDocument 与 ContentWorkspaceDoc
father son

ContentDocument 与 ContentVersion
father son
子类中查父类：
Select Id, VersionNumber, Title, Description, FileType, ContentSize, IsLatest From ContentVersion
父类中查子类：
Select Id, Title, (Select VersionNumber, Title, Description From ContentVersions) From ContentDocument c
Opportunity 与 ContentVersion
father son
子类中查父类
Select VersionNumber, Title, Description, ReasonForChange, OwnerId, TagCsv, FileType, ContentSize, Opportunity__r.Name From ContentVersion
父类中查子类
Select o.Name, (Select VersionNumber, Title, Description, ReasonForChange, OwnerId, TagCsv, FileType, ContentSize From Content__r) From Opportunity o
ContentWorkspace:
Select c.TagModel, c.SystemModstamp, c.Name, c.LastModifiedDate, c.LastModifiedById, c.IsRestrictLinkedContentTypes, c.IsRestrictContentTypes, c.Id, c.Description, c.DefaultRecordTypeId, c.CreatedDate, c.CreatedById From ContentWorkspace c
创建ContentWorkspaceDoc对象时（为当前content指定存放library.），需要ContentDocumentId, ContentDocumentId两个Required Fields.
ContentWorkspaceDoc contentDoc = new ContentWorkspaceDoc();
contentDoc.ContentDocumentId = '06990000000nwlKAAQ';
contentDoc.ContentDocumentId = '05890000000ctNxAAI';
insert contentDoc;
在一个新的环境中，用content等对象：Set up ==> Build ==> Customize ==> Salesforce CRM Content ==> Settings，先设置。再在User对象中的Receive Salesforce CRM Content Email Alerts, Receive Salesforce CRM Content Alerts as Daily Diges三个复选框，设置为true状态。
