basic validations and .valid?

#21

I would love to see some (super-basic) validations support to replace the hacks I've come up with for the moment.

What I am doing now is just making an array of fields I wish to be present, then on before(:create) doing a check like this:

def validate_essentials check = ['name', 'email', 'timezone', 'password'] check.clone.each do |c|

check.delete_if {|x| x == c } if !self[c].blank?

end if check.blank?

return true

else

raise RuntimeError, check.first

end end

That gives me basic validations and a way to pass the missing field around, but as you can see it's not very elegant. It would be nice to be able to set some "required fields" once per class, then have a .valid? method to see if they were all satisfied, hooked into the official save method.

What do you think? Outside the scope of CouchRest? Or useful? : )

thanks for your excellent library btw, it's a pleasure to work with.

sorry, should have checked formatting before posting. Not that the code was particularly valuable, but still ..

Let me give it another shot:

@@@def validate_essentials check = ['name', 'email', 'timezone', 'password'] check.clone.each do |c|
```
check.delete_if {|x| x == c } if !self[c].blank?
```
end if check.blank?
```
return true
```
else
```
raise RuntimeError, check.first
```
end end@@@

So it seems the code formatting just does not work at all. Cool.

Here's a patch for a super-simple implementation of this. All it does is define a number of fields you want to check, eg.

validate :name, :email

And then refuse to save (returns false) if they're not there. Also gives you .valid? and an .invalid_fields method.

Not sure if it's really the kind of thing you have in mind, but works for me :)
