Call a model method in a Controller

Question

I\'m have some difficulties here, I am unable to successfully call a method which belongs to a ProjectPage model in the ProjectPage contro

Three thing:

1.) When you want to create a class wide method thats not limited to an object of the class you need to define it like

def self.method_name
  ..
end

and not

def method_name
  ...
end

2.) This can be done using a scope with lambda these are really nice features. Like This in the model add:

scope :form_search, lambda{|q| where("amount > ?", q) }

Will enable you to call

Project.form_search(params[:price_min])

The secound step would be to add a scope to the ProjectPage model so everything is at the place it belongs to!

3.) When you call a Class method in the Controller you need to specifiy the Model like this:

Class.class_method
