J’ai lu quelque part ici sur Discours, mais je ne parviens plus à le retrouver, un post où quelqu’un a écrit une métrique/statistique utile avec une requête SQL… Il y en a quelques-uns que j’aimerais utiliser…
It is possible to enter the ruby console and run ActiveRecord queries, if you feel more comfortable doing that.
But IMHO, the best way is to use the Data Explorer plugin.
it provides information about tables, fields, and field datatypes
it does only SELECT queries so it is inherently safer because it can not do anything destructive
has built in LIMIT so a poorly crafted query will not bog or crash your site
Some knowledge of the database architecture is still needed, especially for complex queries. But many (IMHO, most) times it is intuitive. eg.
it is clear that the posts table’s posts.topic_id field references the topics table’s topics.id field.
