If the statement is in rails

Question

I am trying to study rails while doing some lab work in railsforzombies, I am in lab3 (if statements).

It has two tables:

• Zombies {id, name, cemetery}
• Tweets {id, status, zombie_id}

Target In each block, if Zombie has more than 1 tweet, print SMART ZOMBIE

<% zombies = Zombie.all %> <ul> <% zombies.each do |zombie| %> <li> <%= zombie.name %> # add if statement here </li> <% end %> </ul> 

I tried some solutions, but I'm wrong.

Answer 1

 <% if zombie.tweets.size > 1 %> Smart Zombie! <% end %> 

Answer 2

<%= 'SMART ZOMBIE' if zombie.tweets.size > 1 %>

Note: count / length / size are all subtly different .

Edit: more than 1.

Answer 3

It works!!

 <% zombies = Zombie.all %> <ul> <% zombies.each do |zombie| %> <li> <%= zombie.name %> <%= 'SMART ZOMBIE' if zombie.tweets.count > 1 %> </li> <% end %> </ul> 

Answer 4

This should work:

 <ul> <% zombies.each do |zombie| %> <li> <%= link_to zombie.name, edit_zombie_path(zombie) %> <%= 'Smart Zombie' if zombie.tweets.count > 1 %> </li> <% end %> </ul>
