Uses length validation to hide add link when you reach maximum # of nested objects

[michaelglass]

no tests yet, but this should work.

continued to implement #46, adding prototype and a few small changes:

by default, using length validators will not be used.

use length validatiors globally with

config.nested_form.use_length_validators = true

in your application.rb

use length validations on a per-association level by passing the :check_maximum option

f.link_to_add :tasks, check_maximum: true

if check_maximum is passed in but a validator can't be chosen (either because there are none or more than 1) link_to_add will raise an NestedForm::UnresolvedLengthValidator error

if you just want to set a maximum without checking a length validator, pass it in

f.link_to_add :tasks, maximum: 5

this will override any length validators

... so Sebastian's thread had some activity, but here there have been crickets.

If I more thoroughly test this feature, will it get merged in?

I would be very interested in this feature. Hope it gets merged in. It'd be great if there was a 'minimum' check as well.

[robertwbradford]

+1 for this. Any update?

assuming this is dead. closing.
