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'' %>
Cheers

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

render :action => ''ingresarUsuario''
end
end
--and here is the view--
<% unless @usuario.errors.empty? %>
<div class="errors">
<p>No se pudo proseguir:</p>
<ul>
<% @usuario.errors.each_full do |msg| %>
<li><%= errortraductor(msg) %></li>
<!-- agregar un traductor como traducir(msg) y
lo ponga lindo, OJALA UN HELPER -->
<% end %>
</ul>
</div>
<% end %>
<%= start_form_tag :action => ''agregadoUsuario'' %>
<br><b><center><%= flash[:notice]
%></b></center>
<%= render :partial => ''update'' %>
<center> <%= submit_tag("Agregar Usuario")

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.
