Re: validation_helpers
OK, I've turned that into a method. And it works now. I thought it might have followed the *before_* situations that *Sinatra* follows. As well, is *Object.valid? *a alias for *Object.validate* as it's not apparent due to the *super*. The individual validates_ methods were fine. It was suggested that I include this plugin after *helpers* and before *models*. Thank you.

I don't see the *validation_helpers* plugin adding a *before_validation* class method: https://sequel.jeremyevans.net/rdoc-plugins/classes/Sequel/Plugins/ValidationHelpers.html You can see in the docs how this plugin only adds some *validates_** methods, which should be called inside the model's *validate* method.

validation_helpers
For some reason I can't get the validation_helpers to load: In the models loader: *Sequel::Model.plugin :validation_helpers* Models are loaded after helpers. Inside the class that's been working: *plugin :validation_helpers* Error: *undefined method `before_validation' for Carrier:Class* It seems like everything is in order, however it isn't loading. What should I be checking? Cheers -- You received this message because you are subscribed to the Google Groups "sequel-talk" group.

Alternative validation_helpers syntax feedback
I've got a working implementation for a plugin that allows an
alternative syntax for the validation_helpers plugin's methods (http://
pastie.org/662251.txt):
def validate
validates do
name do
presence
max_length 10
end
date do
format %r{\d\d/\d\d/\d\d\d\d}
end
number do
presence
integer
end
end
end
This syntax is a lot more verbose than the standard syntax, but I have
a fairly specific use case in mind. The project I'm working on
currently has a table with about 80-90 columns all with validation
requirements. Using the standard syntax, it's difficult to see what
validations apply to each column, since the validations are sorted by
type of validation (e.g. presence, max_length), not by column.
This type of syntax allows me to basically print out the validation
code, sit with project manager, and make sure all desired validations
are being enforced. I think it is more natural to think of all
validations for a given column, versus all columns with a certain
validation type.
Of course, if you only have a few columns, this syntax is just more
verbose. This syntax really only has an advantage when you have many
columns and it is difficult to look at your validate method and see
what validations are being applied to what columns.
Anyway, I'd like to get some feedback as to whether people think this
should be added to the plugins that ship with Sequel.
Also, I'd like to thank Rich Kilmer for the general idea of this type
of syntax. I got the idea from his LoneStar RubyConf presentation on
Encoding Domains.
