Question

Use acts-as-taggable-on for tagging. Based previous questions in SO i read that i must minimize logic in the view and create a helper for conditions in the view template. Here’s my code so far. (newby rails)

Routes:

resources :appartments do
  collection do
    get ':tag', to: 'appartments#index', as: :tag
    end

My controller:

def index
    if params[:tag]
            @apartments = Appartment.tagged_with(params[:tag])
            else
            @apartments = Appartment.all
            end
    end

Application helper:

def render_partials_conditionally
        if @apartments.include?("family")
            render :partial => 'familie'
            if @apartments.include?("groups")
            render :partial => 'groups'
        end
    end
end

The idea (i assume) is that i check if the value “familie” exist in the @apartments array with the include? method

Apartment index view

 = render_partials_conditionally   

When i go to apartments/family the partial _family must showed, but nothing happens…no error, no partails

What am i doing wrong?

Answer 1

If Appartment is a model, @apartments should be an array of objects, so @apartments.include?("family") and @apartments.include?("groups") will never be true.
Instead, the code could be like this:

@apartments.any? { |apartment| apartments.some_field == "groups" }

However I think it is still not good enough. A better approach could be that the helper only return the name of the partial, and then render the partial in view.
