Problem with date

Rails
1

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 :frowning:

Sorry, the search is by date no by data

Now it shows me the view but with all the objects :frowning:

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?

Solved…(mounth/day/year).to_date it’s the correct form. Thanks a lot
