Guyz, How to retain form data while redirecting back to same page? i do not want to work with sessions option. Any other way ..? I mean i am creating a record and after hitting submit button one of my validation failed and the form redirects to the same page where i have to fill the form values again. But this time every text field value are gone.. Googled but no light.. :) -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

But this time every text field value are gone..Controllers typically do not redirect upon validation failures. If you simply render the page again your form data will be available and the Rails framework will kindly repopulate the form fields for you automatically. If you want to know what that code looks like just run a scaffold generator in new Rails project. Follow that pattern in your own controllers and you''ll save yourself a lot of headaches. That being said... a redirect is going to lose the context of the previous request. HTTP is a stateless protocol. This is the reason cookies and sessions exist, and a primary reason why frameworks, such as Rails, are needed. -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

I have a view that is a form in add.html.erb and in the create method in the controller I have validation check if everything in the form is set. If validation finds an error, I do render :action => :add and all the set values are lost. if I just do "render" or nothing, it defaults to the create view. Obviously redirect to add didn''t work either. More suggestions? -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

You may have to supply some code, as render :action => :add should work. Do the variables have the same names? Are there any variables set in the "add" action that aren''t getting set in the "create" action? Rendering an action does not run its controller code, only renders its view template.

I set a cookie but otherwise don''t really have any variables that
cross. I also have other forms that are even simpler (not even the
cookie) and they blank out as well. I also checked my views, no
variables are the same. Thanks for your help.

cookies[:code] = sCode
#determine if code is queriable or not
db = SetupDatabase.new(sCode, current_user.name)
bExist = db.newDatabase()

redirect_to :action => :query

redirect_to :action => :add
