Different behavior of “each” method in development and production
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}
I have table in my ERB-template. Like this:
<table>
<% @users.each do |user| %>
<tr>
<td><%= user.id %></td>
<td><%= user.name %></td>
</tr>
<% end %>
</table>
It works fine. Suppose I have 2 users.
Table will be like this:
1 | foo
2 | bar
But for example, I decide to edit user with id1.
In development it will be correct. Like this:
1 | oof
2 | bar
But in production it will be:
2 | bar
1 | oof
After editing user always jumps to the end of table.
I think it because I use SQLite in local but Heroku uses PostgreSQL.
I'm newbie, so I can be wrong.
 
My question is: how should I change my code to make the code work correctly everywhere?

Explicitly specify order in your controller. If the order is unspecified, PostgreSQL does not guarantee any order, so assume it will be randomized.
@users = User.order(:id)#.limit/pagination
I would also advise you to have the same databases in development and production, if you take some time to setup PostgreSQL locally, it will pay off.
