Self-aware conditions

[asiniy]

Why we need to pass second argument in block? Maybe, it will be better to fetch self object from object through other way, like:

  protect do |user|
    if user
      if model.try(:id) == user.id   # Checks belonging keeping possible nil in mind
        can :update, %w(title text)         # Allow authors to modify posts
      end
    end
  end

instead of current

  protect do |user, article|
    if user
      if article.try(:user_id) == user.id   # Checks belonging keeping possible nil in mind
        can :update, %w(title text)         # Allow authors to modify posts
      end
    end
  end

i.e. carrierwave have a method naming model which can be used in their processing blocks

I can't see any purpose to break the BC. It's just a matter of taste and I'd rather stay with what we currently have.

How can I make a restriction for smth.like that:

    @contractor = Contractor.restrict!(current_user).find(params[:id])

How can I work with restriction to this product?

What exactly are you trying to achieve?

[asiniy]

I want to restrict user access to some contractors.

[inossidabile]

Ok. Use the code that you provided. Read README for better examples. Can you please explain what you want explicitly? How is it even connected to the way we use to reference entity?

I can't read your mind.

There is a controller:

@contractor = Contractor.restrict!(current_accreditation).find(params[:contractor_id])
@contractor.accreditations.create!(options)

So, I want to restrict Contractor accreditation based on contractor itself.

For now, works something like that:

@contractor = Contractor.restrict!(current_accreditation, Contractor.find(:contractor_id)).find(params[:contractor_id])
@contractor.accreditations.create!(options)

ЗЫ. Можно мне по-русски, я по-английски не очень?

[asiniy]

Is anybody here?

[inossidabile]

restrict! does not accept second argument. It appears automatically during the restriction of a single entiy. Just use it.

[asiniy]

Yes, I understood it for now. Regards!
