java - Can I add value in a BindingResult before checking Errors in Spring? -


can add value in bindingresult before checking errors in spring?

@initbinder("memberrequest")     public void initmemberrequestbinder(webdatabinder binder) {         binder.setvalidator(new memberrequestvalidator());     }   @preauthorize("isauthenticated()")     @requestmapping(value = "/save", method = requestmethod.post)     public modelandview saverequest(@valid @modelattribute("memberrequest") memberrequest mr, bindingresult result, httpsession session) {          session.setattribute("phone", mr.getphonenumber());          mr.setwelfare((string)session.getattribute("welfare"));         mr.setschool((string)session.getattribute("school"));         mr.settitle((string)session.getattribute("title"));         mr.setdistrict((string)session.getattribute("district"));         mr.setname((string)session.getattribute("name"));         mr.setfile((string)session.getattribute("file"));         mr.setqueue((string)session.getattribute("queue"));         mr.setrequestor(getuser());         mr.setschool_id((string)session.getattribute("school_id"));         mr.setborough_id((string)session.getattribute("borough_id"));         mr.setretiree((string)session.getattribute("retiree"));           if (result.haserrors()) {             logger.debug("pages had errors on it... returning input page");             return new modelandview("w-question");         } else {

i have above code in spring controller issue need take values out of session , move them bindingresult (bean) before validator runs on it..

can done someone? issues of values keep in session.. please me know if can dont , how best way it..

in controler define method creating model atribute , annotate @modelattribute annotation. not modify binding result object validation target , can change validator behavior change binding result need. 

@modelattribute("memberrequest") public  memberrequest getmemberrequest(httpsession session) { memberrequest mr = new memberrequest();   mr.setwelfare((string)session.getattribute("welfare"));     mr.setschool((string)session.getattribute("school"));     mr.settitle((string)session.getattribute("title"));     mr.setdistrict((string)session.getattribute("district"));     mr.setname((string)session.getattribute("name"));     mr.setfile((string)session.getattribute("file"));     mr.setqueue((string)session.getattribute("queue"));     mr.setrequestor(getuser());     mr.setschool_id((string)session.getattribute("school_id"));     mr.setborough_id((string)session.getattribute("borough_id"));     mr.setretiree((string)session.getattribute("retiree")); return mr;  }

this method called before binding ocures, have in mind method called before each controler method wich using @modelattribute("memberrequest") parameter.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
