How to restore fields ("validates_presence_of")

Rails
1

Hi all,
I am using “validates_presence_of” for validating all fields of my
registration form. It is working fine and generating custom error
message as mentioned.
Also clearing all fields. How can restore those fields which are already
filled.
Problem is “validates_presence_of” clearing (blank) field if it fails,
instead of restoring fields which are already filled.
Help.

Thanks

I believe reloading fields is handled in the controller action for
create, scaffolding builds a create method like:
create
@request = Request.new(params[:request])
if @request.save
flash[:notice] = ‘Request was successfully created.’
redirect_to :action => ‘list’
else
render :action => ‘new’
end
end

the line
@request = Request.new(params[:request])
should reload the submitted values.

should reload the submitted values.

Yes, I am doing in same way, but can not happen. User has to again, fill
all fields, Please suggest if any thing wrong goes.
my controller
##############
def create
#@met = Met.new(@params[‘met’])
@met = Met.new(params[:met])
if @met.save
session[:user] = @met.id
redirect_to :controller =>‘project’, :action => ‘proj’, :id =>
@met.id
else
render_action ‘new’
end
end

Thanks,

Same code works for update module, and restore the fields.
########################
def update
@met = Met.find(params[:id])
@met.save
if @met.update_attributes(params[:met])
redirect_to :controller =>‘project’, :action => ‘proj’, :id =>
@met.id
else
render_action ‘edit’
end
end
