[flexcoders] Re: storing login data from a cfquery for use throught flex app
wow this seems to work but never used singleton before. jeremy, care to explain how staff works in detail? or maybe stinasius may understand what is being done here. if so please share with a flex newbie.
[flexcoders] Re: storing login data from a cfquery for use throught flex app
sorry john, i have never used singletons before either. i have a static class and would like to know how to get it store the result of the query. otherwise i have not made any progress at all. am thinking if someone can work out for me a solid flex/cf/access login(authentication) system and well commented that i can use in my projects i am prepared to pay for it.
[flexcoders] Re: storing login data from a cfquery for use throught flex app
hi, may be i will try to put the question this way, in my cfc i have to return
a Boolean value true or false because in my result handler on the login page
i test to see if the result returned is true or false then make a decision to
accept login or not. this is my result handler on the login page
private function login_result(event:ResultEvent):void
{
// login successful, remember the user.
if( event.result == true || event.result == TRUE ||
event.result == 1 || event.result == 1 )
{
this.dispatchEvent( new
Event('loginSuccessful') );
}
else
{
// login didn't work. show message
errorMessage(Login unsuccessful);
}
}
but if i set the cfc to return a query result in this case
checkAuthentication nothing happens. so is there a way of returning a query
result and have the result handler check against the returned result in order
to make a decision to authenticate or not?
RE: [flexcoders] Re: storing login data from a cfquery for use throught flex app
What I do is to use xml. I wrap all of my return server data in a status
node, like this successful login:
callstatus status=success statusDescription=User authenticated
userInfo first=John last=Smith email...@gmail.com ./
/callstatus
If the login fails, I return:
callstatus status=fail statusDescription=credentials are not valid /
In the handler I do:
var xmlResult:XML = XML(event.result); //musy have resultFormat=e4x
if (xmlresu...@status == success) {
UserInfo.first = xmlresult.userin...@first;
.
}
else {
Alert.show(Login Failed: +xmlresu...@statusdescription )
}

[flexcoders] Re: storing login data from a cfquery for use throught flex app
i have also had the same problem with login authentication in flex and coldfusion. this is not well addressed especially for beginners like me.i wish someone could come up with a tutorial that does login authentication through database and cfc remote object calls and then shows how to store login info for use through out the application. so far i have to say i am where stinasius is and failed to progress.
[flexcoders] Re: storing login data from a cfquery for use throught flex app
give this a try , the problem may be the return type, struct for successful
and boolean for unsuccessful
cffunction name=loginUser access=remote returntype=struct
//do your stuff
cfset returnValue = structnew()
cfset returnValue.success = false
cfset returnValue.lastResult =
cfif checkAuthentication.recordCount EQ 1
cfset returnValue.success = true
cfset returnValue.lastResult = checkAuthentication
/cfif
cfreturn returnValue/
/cffunction
private function login_result(event:ResultEvent):void
{
if(Number(event.result.success) == 1 ||
String(event.result.success).toLowerCase() == true)
{
this.dispatchEvent( new Event('loginSuccessful') );
var store:ArrayCollection = new
ArrayCollection(ArrayUtil.toArray(event.result.lastResult))

[flexcoders] Re: storing login data from a cfquery for use throught flex app
Valdhor, i think what stinasius is asking abt has nothing to do with the links you provided. bruce phillip's example is about login in flex with coldfusion backend. the problem is not the login, the problem is how to store the result of the login query in the static class for use throughout the flex example. say the user wants to edit his info like username, email, date of birth etc he/she has to first login and then edit the info returned by the cfc query.
[flexcoders] Re: storing login data from a cfquery for use throught flex app
Which is just an extension of the examples at the links I provided. By using Bruce Phillips example; The CRUD example at http://flexcf.com/tutorials; and the Ben Forta Adobe TV presentation at http://www.adobe.com/devnet/coldfusion/articles/adobetv_cfpwrdflex.html, anyone should have a good idea at how to do what stinasius wants. All it requires is creating a value object in Flex with username and password; Sending that object to coldfusion and receiving a userinfo value object back containing authentication info and, if authenticated, all the users details. With my extremely limited knowledge of ColdFusion I could probably have something that works in about four hours. If someone wants to pay me for my time I would be happy to put together an example ;-} --- In flexcoders@yahoogroups.com, johndoematrix johndoemat...@... wrote: Valdhor, i think what stinasius is asking abt has nothing to do with the links you provided. bruce phillip's example is about login in flex with coldfusion backend. the problem is not the login, the problem is how to store the result of the login query in the static class for use throughout the flex example. say the user wants to edit his info like username, email, date of birth etc he/she has to first login and then edit the info returned by the cfc query.

hi how do i assign the properties of UserInfo in the result handler?
[flexcoders] Re: storing login data from a cfquery for use throught flex app
This can be done fairly simply using an oop approach.
With out going into to much detail. You can create a single instance of a
storage class that gets/sets the data that you are looking for.
Here is a really basic example:
package com.login{
// do some imports
public class myLogin{
private var username:string = new String();
private var email:string = new String();
public function myLogin(){
// do some constructor stuff here
}
public function getUsername():String{
return username;
}
public function getEmail():String{
return email;
}
public function setUsername(username:string):void{
// set your username
}
public function setEmail(email:string):void{
// set your email
}
}
}
So when you first instantiate your class you set the username/email. Then all
you will need to do is use getUsername/getEmail to retrieve the data that you
are looking for.
One last point make sure you that only instantiate the myLogin class once.
