Symfony 1.4
Doctrine
admin backend application
With this simplified schema:
Product:
columns:
code: { type: string(10) }
name: { type: string(100) }
DeliveryRow:
columns:
product_id: { type: integer , notnull: true }
qty: { type: decimal(8,2) }
relations:
Product: { onDelete: RESTRICT , local: product_id , foreign:
id, foreignAlias: DeliveryRows }
I need to have the product name field on the delivery row form, but
the user must not be able to change the product_id value.
I tried this in several ways, but none with the desired result.
1) If I do nothing, I get a product combo in the form. It correctly
shows the product name, but I cannot put the widget in readonly mode.
I can disable it, but this doesn't work, as the validation fails on
save... missing product_id.
2) I tried a readonly text input widget. That works quite well for the
created_at and updated_at fields... but not in this case. If I use it
for the product_id field, it will show the id, and not the product
name. I tried setting it on product_name, product and many other
variations, but it either doesn't work, or I haven't found the correct
way to use that... I just get an empty readonly text input field.
3) I tried a custom field _readonly_product_name, defined in the
generator.yml. I wrote a getReadonlyProductName method in the model.
Again, I just get an empty readonly text input field.
4) I tried using a partial template field. I read that partials gain
automatic access to the current object... so I tried referencing
something like $deliveryRow->getProduct()... $deliveryRow-
>getProduct()->getName()... and many others... I just got a bunch of
undefined variable errors.
5) As a last resort, I was thinking I could embed a special product
form in the delivery form, with just the product name field in
readonly. I haven't tried this one yet, as it seems a bit more
complicated... embedded forms just don't look too right, and I'd have
to work on it a bit to make it look like a field in delivery row main
form.
But I mostly think I just missed something... it wouldn't seem to be
that difficult. Any ideas or pointers (tutorials, howtos)?
TIA and regards,
