{{=db.publicaciones.descripcion.represent(tipo_3.descripcion,tipo_3}}

I do not think you want the extra =.

 Hello,

 I need to truncate a field that contains HTML content. 

 Now i'm using htmltruncate  in 
 a controller that return a SQLFORM.smartgrid and it works perfect:
  
 def noticias():
 
 db.noticias.cuerpo.represent = lambda field,row: 
 XML(htmltruncate.truncate(field, 100))
 grid = SQLFORM.smartgrid(db.noticias, 
 linked_tables=['adjuntos_noticia'])

 return dict(grid =grid)


 But when I try to implement a in a controller in this way:

 def index():
 db.publicaciones.descripcion.represent = lambda field, row: 
 XML(htmltruncate.truncate(field, 10))
 tipo_3 = db(db.publicaciones.tipo == 3).select().last()

 return dict(tipo_3 = tipo_3)


 It doesn't work


 The module is inside the "modules" folder of the app and it's imported 
 via:
 import htmltruncate


 any help is welcome!

 Best!

[villas]

I end up doing something like this:

{{=db.publicaciones.descripcion.represent(=tipo_3.descripcion,tipo_3)}}

I hope that helps,  but maybe there is a better way?

Hi Massimo,

Sorry for my poor explanation.

What I don't get is in the view when i call the field value 
{{=tipo_3.descripcion}}  I get the whole text and not the truncated one 
like in the SQLFORM.grid case.

What does it mean it does not work? Can you import it? Can you import it 
from python?
