how to get url for a tab using apex (in the vf controller)?
I'm overriding "delete" on std object Asset, pointing it to a vf page whose controller should either delete the asset or (if it has related custom objects) redirect to a vf page which warns the user that these relationships will be broken, dispays the related list, and offers a "delete anyway" button.
Following delete of the asset, I want to emulate standard salesforce behavior, that is, display the Products tab home page.
How can I determine the url of the Products page within my apex controller?
Hi TLF,
The info you need is actually in my additional posts above, but a bit scattered. Here's some code that should work:
Map<String, Schema.SObjectType> gd = Schema.getGlobalDescribe(); Map<String,String> prefixKeyMap = new Map<String,String>{}; for(String sObj : gd.keySet()){ Schema.DescribeSObjectResult r = gd.get(sObj).getDescribe(); prefixKeyMap.put(r.getName(), r.getKeyPrefix()); } String threeLetterCode = prefixKeyMap.get('Asset'); PageReference pageRef = new PageReference(threeLetterCode); system.debug( pageRef.getUrl() );

In the process of development, my code operates in a different way, and has no need to display that tab.
However, I think that you can just do new ApexPages and set partial-url to '/three-letter-code' for any object that has a tab (including all standard objects). The three letter code for Product2 is 01t. But I don't recommend you hard-code it. Instead, steal a small bit of the code shown below to dynamically determine this code.
I wanted a list of all three letter codes, and I extracted them with this combination of apex and some manipulation in my text editor:
Map<String, Schema.SObjectType> gd = Schema.getGlobalDescribe();
Map<String,String> keyPrefixMap = new Map<String,String>{};
Set<String> keyPrefixSet = gd.keySet();
for(String sObj : keyPrefixSet){
Schema.DescribeSObjectResult r = gd.get(sObj).getDescribe();
String tempName = r.getName();
String tempPrefix = r.getKeyPrefix();
System.debug('Processing Object['+tempName + '] with Prefix ['+ tempPrefix+']');
keyPrefixMap.put(tempPrefix,tempName);
}
for (String foo : keyPrefixMap.keySet()) {
system.debug( foo + ' ' + keyPrefixMap.get(foo));
}
// Run the above somewhere that you can snag the debug output
//(workbench, or system log, or exec anonymous in IDE or TextMate).
//
// then do the following steps in editor or shell
//
// replace .* ([a-zA-Z0-9]{3} [a-zA-Z0-9_]+)$ with $1
// sort

Ah, thanks. I knew that I could provide the three character id of the tab to render the tab, the part that I was unclear on was how to dynamically determine the id of a tab. I'll try your suggestion.
Friend,
Did you got any solution for this issue, I am also having a requirement like, Dynamically get the "web tab url" on apex controller in order to redirect to another "web tab" page. without hardcode the web tab url, if any solution should be thanks full.
Hi TLF,
The info you need is actually in my additional posts above, but a bit scattered. Here's some code that should work:
Map<String, Schema.SObjectType> gd = Schema.getGlobalDescribe(); Map<String,String> prefixKeyMap = new Map<String,String>{}; for(String sObj : gd.keySet()){ Schema.DescribeSObjectResult r = gd.get(sObj).getDescribe(); prefixKeyMap.put(r.getName(), r.getKeyPrefix()); } String threeLetterCode = prefixKeyMap.get('Asset'); PageReference pageRef = new PageReference(threeLetterCode); system.debug( pageRef.getUrl() );
There is a much more straightforward solution, using URLFOR, here.
Salesforce: Please, please, please document the uses and arguments of URLFOR! We shouldn't have to hunt so much!
I would be reluctant to hardcode the 3 character keys even for standard objects. I agree they probably will never change. Rather than do a global describe for the whole org and throwing away 99% of the information returned I would suggest the following in your VF controller.
String ObjectPrefix = {Insert Object Name Here}.sObjectType.getDescribe().getKeyPrefix(); PageReference p = new PageReference('/'+ObjectPrefix); p.setRedirect(true); return p;This way you are only retrieving what you need and it works for custom objects....across your different orgs.
Cheers!
Thank you Shikibu!!
Even though you can get this value through a $URLFOR call, your utility method works great when you want to redirect as a result of an action method. For example, in the save() method in a custom controller that has a RichText field or an apex:inputFile in the VF page. In this scenario you can't get away with using oncomplete since this is not allowed (along with rerender) in combination with RichEdit or inputFile.
So now I can use the straightforward:
<apex:commandButton value="Save" action="{!save}"/>with my modified version of your code in my controller:
public PageReference save() { PageReference retVal = getURL(); ... return retVal; } private PageReference getURL() { // Get describe info and populate prefix map Map<String, Schema.SObjectType> gd = Schema.getGlobalDescribe(); Map<String,String> prefixKeyMap = new Map<String,String>{}; for(String sObj : gd.keySet()) { Schema.DescribeSObjectResult r = gd.get(sObj).getDescribe(); prefixKeyMap.put(r.getName(), r.getKeyPrefix()); } // Get prefex for MyCustomObject__c String threeLetterCode = prefixKeyMap.get('MyCustomObject__c'); // Create pageRef from prefix PageReference pageRef = new PageReference('/' + threeLetterCode + '/o'); // Return page MyCustomObject__c.Tab return pageRef; }Thanks again!! Much appreciated.

return new PageReference('/'+Account.sObjectType.getDescribe().getKeyPrefix()+'/o');Here Account can be replaced with the Object name of your choice
