Hi, first and foremost sorry for my english. I have a pbroblem trying to
built a search by data.
My view is a simple text_field:
<% form_tag ({:action =>'buscadata'},{:class => 'lgn'}) do%> <!--
cuando pulse el boton ira a buscadata de lgn -->
<%= stylesheet_link_tag "show" %>
<h1>Busqueda por fechas de LGN</h1>
<p>
<b><%='Introduzca Fecha inicial (DD/MM/AA)'%></b><br /> <!--para
introducir dia mes y año del inicio de la busqueda-->
<%= text_field_tag :dia, params[:dia_ini]%>
<%= text_field_tag :mes, params[:mes_ini]%>
<%= text_field_tag :any, params[:any_ini]%>
</p>
<p>
<b><%='Introduzca Fecha Final (DD/MM/AA)'%></b><br /> <!--para
introducir dia mes y año del inicio de la busqueda-->
<%= text_field_tag :dia, params[:dia_fin]%>
<%= text_field_tag :mes, params[:mes_fin]%>
<%= text_field_tag :any, params[:any_fin]%>
</p>
<%= submit_tag "Buscar entre las fechas seleccionadas", :name=>nil%>
<%end%>
-------------------------------------------
In the controller I search @lgns created between the two dates:
def buscadata
date1
=parse_date("#{params[:any_ini]}/#{params[:mes_ini]}/#{params[:dia_ini]}")
date2
=parse_date("#{params[:any_fin]}/#{params[:mes_fin]}/#{params[:dia_fin]}")
if date1 and date2
@lgns=Lgn.find(:all, :conditions => ['created_at >=? and
created_at <=?', date1, date2 ])
end
end
######################################################################################################
private
def parse_date(str, format='%Y/%m/%d')
begin
date = Date.parse(str, format) #strptime
return date
rescue ArgumentError
return false
end
end
----------------------------
Finally I show @lgns find, buscadata view it's the same that index view.
But I have a problem, @lgns it's a nil object. Somebody can help me?? I
cant see whats wrong :(
