Validations erasing the form

Hi there
I have a for with a couple of text_fields. I’m doing some validation
via the model and when the validation “works” I get there was an error
on blah blah
the problem is the form is erased and I have to fill up the form again!
I saw that scaffold keeps the form filled when the validation “works”
but I dont know exactly what’s making it happen!
I would like to know how to make this work

Thanks in advance
Jorge

You need to have the model assigned to an instance variable that is
named the same as the model parameter that you pass into the text_field
helper. This way the variable is within scope of the view and can be
used by the text_field helper.

Controller

def create
@cheese = Cheese.new(params[:cheese])
if @cheese.save
#do whatever on success
else
render 'your_view
end
end

View

<%= text_field ‘cheese’, ‘name’ %>

Hi there an thanks for answer,
I have it just like that but still does not work here is my data
I dont know what i’m doing wrong

def ingresarUsuario
@usuario = Usuario.new
@cursoslist = Cursos.find(:all)
@tipo = Tipousuario.sacar
end

def agregadoUsuario
@cursoslist = Cursos.find(:all)
@tipo = Tipousuario.sacar
@uid = params[:usuarios][:strid]
@cur = params[:cursostomados]

#-------------------- insertamos el usuario primero -------
a = Usuario.randompass(8)

@k = {
	"strnombres"   =>  params[:usuarios][:strnombres],
	"strapellidos" =>  params[:usuarios][:strapellidos],
	"strid"	       =>  params[:usuarios][:strid],
	"stremail"     =>  params[:usuarios][:stremail],
	"inttipo"      =>  params[:usuarios][:inttipo],
	"strdireccion" =>  params[:usuarios][:strdireccion],
	"strtelefono"  =>  params[:usuarios][:strtelefono],
	"strlogin"     =>  params[:usuarios][:strlogin],
	"strclave"     =>  a
	}

	@usuario = Usuario.new(@k)
	#si el usuario crea, entonces lo agregamos a cursosxusuarios
	if @usuario.save
        usuario = 

Usuario.find_by_stremail(params[:usuarios][:stremail])
RegistroMail.deliver_bienvenido(usuario)
if @cur
@cur.each do |cursos_id, do_it|
if do_it == ‘1’
datas = Hash.new
datas = {“idusuario” => @uid,
“idcurso” => cursos_id
}
@cursosxusuario = Cursosxusuario.new(datas)
if @cursosxusuario.save
#agreguame un error en caso de que falle

 		      else
    	        flash[:notice] = "Error al matricular usuario al curso"
                render :action => 'buscarusuario'
 		      end
		   end
		  end
        end
        flash[:notice] = "Usuario Agregado al Sistema"
        redirect_to :action => 'ingresarUsuario'
	else
		flash[:notice] = "Hubo errores en la forma, Revisela e intente de 

nuevo"
render :action => ‘ingresarUsuario’
end

end
–and here is the view–
<% unless @usuario.errors.empty? %>


No se pudo proseguir:



    <% @usuario.errors.each_full do |msg| %>
  • <%= errortraductor(msg) %>


  • <% end %>


<% end %>
<%= start_form_tag :action => ‘agregadoUsuario’ %>

<%= flash[:notice] %>
<%= render :partial => ‘update’ %> <%= submit_tag("Agregar Usuario") %> <%= end_form_tag %>

I think I see your problem. Instead of doing
render :action => ‘ingresarUsuario’
replace this with
render ‘ingresarUsuario’ in the last part of the function where you deal
with errors.
