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%\>   
\<%= stylesheet\_link\_tag “show” %\>

# Busqueda por fechas de LGN

**\<%='Introduzca Fecha inicial (DD/MM/AA)'%\>**  
 \<%= text\_field\_tag :dia, params[:dia\_ini]%\> \<%= text\_field\_tag :mes, params[:mes\_ini]%\> \<%= text\_field\_tag :any, params[:any\_ini]%\>

**\<%='Introduzca Fecha Final (DD/MM/AA)'%\>**  
 \<%= text\_field\_tag :dia, params[:dia\_fin]%\> \<%= text\_field\_tag :mes, params[:mes\_fin]%\> \<%= text\_field\_tag :any, params[:any\_fin]%\>

\<%= 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 ☹

Sorry, the search is by date no by data

</div>

Now it shows me the view but with all the objects ☹

My new code:

CONTROLLER:  
def buscadata  
date1  
=parse\_date("#{params[:dia\_ini]}/#{params[:mes\_ini]}/#{params[:any\_ini]}")  
date2  
=parse\_date("#{params[:dia\_fin]}/#{params[:mes\_fin]}/#{params[:any\_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 =str.to\_date #Date.parse(str, format)  
#strptime  
return date  
rescue ArgumentError  
return false  
end  
end

the view when I introduce the date:  
\<% form\_tag ({:action =\>‘buscadata’},{:class =\> ‘lgn’}) do%\>   
\<%= stylesheet\_link\_tag “show” %\>

# Busqueda por fechas de LGN

**\<%='Introduzca Fecha inicial (DD/MM/AA)'%\>**  
 \<%= text\_field\_tag :dia\_ini, params[:dia\_ini]%\> \<%= text\_field\_tag :mes\_ini, params[:mes\_ini]%\> \<%= text\_field\_tag :any\_ini, params[:any\_ini]%\>

**\<%='Introduzca Fecha Final (DD/MM/AA)'%\>**  
 \<%= text\_field\_tag :dia\_fin, params[:dia\_fin]%\> \<%= text\_field\_tag :mes\_fin, params[:mes\_fin]%\> \<%= text\_field\_tag :any\_fin, params[:any\_fin]%\>

\<%= submit\_tag “Buscar entre las fechas seleccionadas”, :name=\>nil%\>

\<%end%\>

the view when I show the results it’s like the index view

Have you checked whether your parse\_date function is creating the  
correct dates?
