今回はdivで作成したbox自体にリンクをつけたい場合
link_to
<% @wants.each do |want| %>
<%= link_to(want) do%>
<div class="box">
<div class="back_img">
<%= image_tag want.image.variant(resize_to_limit: [200, 200])%>
<p class="under_text">¥<%= want.money %></p>
</div>
<%= want.name %>
<small><%= want.category.name %></small><br>
<small><%= want.created_at %></small>
</div>
<% end %>
aタグを使う方法
<% @wants.each do |want| %>
<a href="<%= want_url(want) %>">
<div class="box">
<div class="back_img">
<%= image_tag want.image.variant(resize_to_limit: [200, 200])%>
<p class="under_text">¥<%= want.money %></p>
</div>
<%= want.name %>
<small><%= want.category.name %></small><br>
<small><%= want.created_at %></small>
</div>
</a>
<% end %>
