Ruby how to get array with boolean?

Question

i would like to get a arrau of boats, but i would like that just show the boats with rent boolean set to true.

how can acomplish this?

i've added:

@boats = Boat.where(rent: true)

But did not worked

i even tried the method model

def rents
    self.class.where(rent: true)
  end

and did not worked either

Do you want an array of the names? or you you want a hash of objects? @boats = Boat.where(rent: true) should've worked if you have your tables setup properly for a set of objects. — bryanfeller

What do you mean by did not worked? Was there an error? What was the error message and how did the stack trace look like? Or did you receive an unexpected result? How did it look like? — spickermann

Your code seems OK, do you get an error when you try to execute the code? that might help. — chrisgeeq

@boats = Boat.where(rent: true) should work. Make sure that you actually have boats with rent = true — B-M

You can do something like this

<% @boats.where(:rent=>true).each do |t| %> 
 <%= t.name %>
<%end%>
<%= @boats.where(:rent=>true).all %>

or

<% if boats.where(:rent=>true).exists?  %>
 <%= t.name %>
<%end%>

or

def rents
 @boats.where(:rent=>true).all
end
