Add possibility to add schema to her model about her HOT 9 CLOSED

Can you describe what you exactly mean?
Normally, the API which Her connects to defines the schema/models and interacts with a database.

from her.

Not sure if that's what the OP meant but sometimes it's necessary to define attributes on which validation has to be performed.

I'm using the active_attr gem with her to achieve this.

from her.

I'm in the process of making Her compatible with ActiveModel (see the activemodel branch). I might add active_attr in it too!

from her.

We had the same problem. Our current solution (even if not optimal) is to make an API call via Her to get an empty object with all attributes where needed (mostly form building). This prevents us from defining attributes in every app that uses Her models.

The main goal was for validation indeed

from her.

Validation should be done by the API and not by the application using the API as this would lead code duplication.

from her.

When using rails it takes the model validation to return errors in forms and you don't goto the API until you know that your model is valid, but if HER is made compatible with ActiveModel then it should be sufficient as that also concludes validation

from her.

Hey guys, I just released her-0.5(.1) which adds an attributes method to model classes. With it, you can actually use ActiveModel::Validations and ActiveModel::Dirty modules (that are now included in all models):

class User
  include Her::Model

  attributes :fullname, :email
  validates :fullname, :presence => true
  validates :email, :presence => true
end

@user = User.new(:fullname => "Tobias Fünke")

@user.fullname_changed? # => true
@user.changes # => { :fullname => [nil, "Tobias Fünke"] }

@user.valid? # => false
@user.errors.full_messages # => ["Email can't be blank"]

@user.save
# POST /users&fullname=Tobias+Fünke will still be called, even if the user is not valid

I’m not a big fan of validating data on the client (since the API always has the last word before creating/updating resources) but it can be nice to manually validate the data before calling the API.

from her.

I’m gonna close this issue now since there’s now a way to add a schema to models (with the attributes method).
