Current User

[RolandS]

Hi Guys,
Im alittle confused by this one.
Im calling the a5ws_getcurrentuser() as the default in a text field.
After log in through a browser i get the user name as expected. But when used through a mobile app built with cordova i get nothing.

Ive also tried using some code that was provided in some docs to call the user name or show "no logged in user"
again through a browser i get the username but through the app (which does have a login component) i get no user.

any help would be great. Im totally stumped.

Thanks
Roland

Not sure if this is the Alpha preferred way or if someone has a better way, but I always just set a local storage variable upon login and read from it if I need the current user.

[RolandS]

Thanks for the Reply Rusty. Could you please give me a idea of how you set the variable on login.

[RustyB]

Sure. If you are using the Alpha method for logging in, you may have used the Persistent Login template. In which case you likely have an XBasic function called xbLogin as c (e as p). In it you will see where the user name gets set

username = e.datasubmitted.userid

Then at the very end of this function, you will see a section where you can create a Javascript response to send back to the client. You can use code similar to the following.

jsOut = jsOut + "localStorage.setItem('userid', '" + js_escape(userName) + "');"

You can then read the local storage variable anytime in your app

localStorage.getItem('userid')

Hope this is helpful.

Thanks Rusty,
I am using the persistent login in template.
Altho in the xbasic functions tab i have nothing. Or an i look in the wrong place

Thanks

ok ive found the onLogin xbasic function on the server side events (Sorry its late, really should have know that) I am missing something tho.
I have added the code
jsOut = jsOut + "localStorage.setItem('userid', '" + js_escape(userName) + "');"

but i get an error (userName) variable not found

[RustyB]

It should be there

Interesting. When I do a brand new ux it is there for me. Perhaps you chose another template when you set up your security initially

Well, regardless you can do something similar, but it would have to be on the Client-side afterLogin. For example

{dialog.object}.setValue('userID', e.userNameFriendly, false);

For this to work, I believe you would have to set the Server-side onLogin userrNameFriendly

e.userNameFriendly = e.username

[RolandS]

yes you are correct. Turns out i had used the Non persistent template and had just turned on the options in properties.
Thanks for the help Rusty, Ill get some sleep and come back to tackle it again in the morning. Alpha and no sleep don't seem to mix very well :)

[CharlesParker]

wait till you start dreaming about your application and what you can do to fix something or that new thing your working on...sleep is when your brain has a chance to catalog all that stuff your trying to remember!

[RolandS]

Yes Charles that has been an issue in the past. its not all bad tho

[RolandS]

ok so for some reason im still struggling with this and it really should be this hard.
I have put the code into the xbasic function on the login component

Then in the on render completed event i have add just something basic that should pull the local storage and fill the Field 'GuardUser' with the userId

But it does nothing and the field stay black.

What have i missed?

[RustyB]

It might be a timing issue. When does onRenderComplete fire. If you aren't sure, put a console log to be sure it is actually firing when you think it is.

You can put any Javascript in the jsOut of xbLogin. Why not just do

jsOut = jsOut + "{dialog.object}.setValue('GuardUser', '" + js_escape(userName) + "');"
