Error de principiante con el scaffold

Community ES
1

Hace varias semanas que no podia hacer nada en RoR y lo tengo un poco
atascado.

hoy con un poquito de tiempo me he puesto otra vez comenzando un
proyecto desde cero:

creo una bd y una tabla en mysql

luego
c:\rails rails rana

edito el archivo de configuracion de la BD
y creo el scaffold

c:\rails\rana\ ruby script/generate scaffold empleados empleados

los archivos se crean correctamente,

arranco el WEBrick

y en el explorador pongo
http://localhost:3000/empleados/ pero me da un extraño error:

uninitialized constant Empleado

RAILS_ROOT: ./script/…/config/…

`require’
script/server:3

This error occured while loading the following files:
empleado.rb

y no se poq porq ante siempre me funciono bien, ¿sera que no hago bien
el scaffold?

lo curioso es que
http://localhost:3000/empleados/new

funciona y guarda correctamente en la BD

seguro que es una tonteria, alguien me ayuda?

2

Creo que los modelos tienen que ir en singular. Prueba a generar el
scaffold
con empleado, en vez de empleados.

3

gracias entonces como seria?

ruby script/generate scaffold empleado empleados

el primero es el modelo y el segundo el controlador?

ya no lo recuerdo, pues hace unos mese que lo mire.

4

Ah, ni me había fijado en que habías puesto dos veces empleados. Yo te
decía
“ruby script/generate scaffold empleado”.

Ahora me surge una duda, ¿iría en mayúscula?

5

Hola lamacarena, sería:

ruby script/generate scaffold Empleado

o sea, el nombre del modelo en singular.

Saludos,
Jaime

En principio es en mayúscula, pero creo que da igual.

Con “ruby script/generate scaffold Empleado” te generará el controlador
“empleados”. Pero puedes especificar otro nombre para el controlador,
por ejemplo “ruby script/generate scaffold Empleado TrabajoBasura”
