Salesforce 自定义对象和附件

Question

Ok, I've been tasked with creating a custom salesforce object that saves some data. That's the easy part.

Where I'm struggling is adding a piece to upload files associated with the record created in the custom object.

The custom object is essentially a form with fields on it. But I also need to upload relevant files.

So I built the form part of the custom object. I used an Apex class and a VisualForce page for the "upload" part.

Unfortunately, in the course of testing, I keep getting errors on the VisualForce/Apex piece.

The errors I get are the following:

Parent: Parent ID: id value of incorrect type: 00590000000yBOmAAM

And my Apex class looks like this:

    public with sharing class FileToDocument {
    public Attachment attachment{
        get{
            if(attachment == null)
                attachment = new Attachment();
            return attachment;
        }
        set;
    }           

    public PageReference upload(){
        attachment.OwnerId = UserInfo.getUserId();
        attachment.ParentId = '00590000000yBOm';
        attachment.IsPrivate = false;

        try{
            insert attachment;
        }
        catch(DMLException e){
            ApexPages.addMessage(new ApexPages.message(ApexPages.severity.ERROR, 'Error Uploading Attachment'));
            return null;
        }
        finally{
            attachment = new Attachment();
        }

        ApexPages.addMessage(new ApexPages.message(ApexPages.severity.INFO, 'Attachment Uploaded Successfully'));

        return null;
    }
}

I am very much a novice at SalesForce. I think the problem is the ParentID line, but I don't know exactly how to fix it.

What I'm trying to do is to be able to upload/attach documents to a record, while I'm filling out the form for the record.

My VisualForce looks like this:

<apex:page controller="FileToDocument">
    <apex:form enctype="multipart/form-data">
        <apex:pageMessages />
        <apex:pageblock >
            <apex:pageBlockButtons >
                <apex:commandButton action="{!upload}" value="Attach"/>
            </apex:pageBlockButtons>

            <apex:pageBlockSection showHeader="false" columns="2" id="block1">
                <apex:pageBlockSectionItem >
                    <apex:outputLabel value="File Name" for="fileName"/>
                    <apex:inputText value="{!attachment.name}" id="fileName"/>
                </apex:pageBlockSectionItem>

                <apex:pageBlockSectionItem >
                    <apex:outputLabel value="File" for="file"/>
                    <apex:inputFile value="{!attachment.body}" filename="{!attachment.name}" id="file"/>
                </apex:pageBlockSectionItem>
            </apex:pageBlockSection>
        </apex:pageblock>
    </apex:form>
</apex:page>

So what could I be doing wrong? My other thought is that there's simply no way to upload appropriate files until after the record has been created. Even then, I think I'd still need to know how to associate it with the Parent ID.

Any help is greatly appreciated, as always.

This is no longer relevant. The project was reassigned to a different group.
