And this is the code of the relation:



$crud->set_relation_n_n('grupo','nombre_grupo_has_usuarios','nombre_grupo','usuarios_idUsuario','nombre_grupo_idgrupo','nombre_g');


Just in case, the fields:



$crud->fields('idUsuario','nombre','apellido','direccion','fijo','celular','email','grupo');


Thank you for your help, i had been trying this all day but omg. :unsure:

I've similar problem when using "varchar" field as primary key
Can you make sure that all of your primary key table is "integer" and "auto-increment"?

And, for relation_n_n, have you check this documentation: http://www.grocerycrud.com/documentation/options_functions/set_relation_n_n
