This variable is used by (newButton) to create a new object. This is correct. When, however, David wants to edit DB objects, then the +E/R prefix is right. But then the 'form' needs an object to be enabled. The key is to call the 'idObj' function in the form. Usually this is done in a header like ( NIL ( (: nm))) '' internally call 'idObj' which takes care of handling the DB objects. Another - more standard - way is to use 'idForm' (menu ,"Title" (idForm ,"Title" '(chocls) 'nr '+cls T '(may Delete) '((: nr) " -- " (: name)) ... ) ) ♪♫ Alex -- UNSUBSCRIBE: mailto:picolisp@software-lab.de?subject=Unsubscribe
GUI components are disabled
Hello list, I'm trying to create a registration form styled with pure.css but all the fields are disabled for some reason. Code snippets: (class +Person +Entity) (rel id (+Need +Key +Number)) # Unique ID. (rel name (+Need +Sn +Idx +String))# Name (rel email (+String)) # Email [de person-reg () (app) (action (html 0 "PicoLisp rules" *Css NIL (viewport-meta-element) ( 60) (top-nav) ( "content-wrapper" ( 'content ( 'pure-g ( "l-box-lrg pure-u-3-5 pure-u-md-2-5 pure-u-sm-1" #(get (default *ID (val *DB)) 'name) (form NIL (gui '(+E/R +TextField) '(name : home obj) 40 "Name") (gui '(+E/R +TextField) '(email : home obj) 40 "Email") (newButton T Dst '(+Person) 'name *Name 'email *Email) ] ### GUI ## [de top-nav () ( "header" ( "home-menu pure-menu pure-menu-horizontal pure-menu-fixed" ( 'a '((href . "!homepage") (class . "pure-menu-heading")) "Direct2Dr") ( "pure-menu-list" ( "pure-menu-item pure-menu-selected" ( 'a '((href . "!homepage") (class . "pure-menu-link")) "Home") ) ( "pure-menu-item" ( 'a '((href . "#") (class . "pure-menu-link")) "About") ) ( "pure-menu-item" ( 'a '((href . "#") (class . "pure-menu-link")) "Contact") ) ( "pure-menu-item" ( 'a '((href . "#") (class . "pure-menu-link")) "Privacy & Security"] [de footer () ( "footer l-box is-center" Word to our footer!) ] In the docs I see that gui is a front-end to new in a get request. What if I don't have anyone in the database yet? How can I create a form which will take basic info via gui and connect it to the db? I know I'm missing something really basic here, please point me in the right direction. Thank you all. -David Bloom
