如何在 Rails 上的 Ruby 中将两个参数从 controller 传递到 model？

Question

I want to pass two params that I am introducing in an input en the index view. This is what i have in the index (the style doesn´t matter):

<form action="/cars" method="GET">
      <input type="text" name="from" placeholder="From" value="<%= @from %>"/>
      <input type="text" name="to" placeholder="To" value="<%= @to %>"/>
      <input style="color:white; border-radius: 2px; padding: 10px; margin-right: 20px; font-family: 'Montserrat', sans-serif; background-color: black; " type="submit", value="SUBMIT" />
</form>

After this, in the cars_controller I have the following:

if params[:from] && params[:to]
      @cars = @cars.filter(params[:from, :to])
end

Finally in my model, i have my function that works with The:from and:to params in a specific way to filter the cars, it doesn´t matter what´s inside. My method is like the following:

def filter(from, to)
end

So the problem comes when, in the index view, I introduce the:from ant:to params by hand, press teh submit button and it returns me "wrong number of arguments (given 2, expected 1)"

Answer 1

 @cars = @cars.filter(params[:from] , params[:to])
