acts-as-taggable-on: rechercher des balises portant le nom LIKE, trier par tag_counts?

Question

Salut J'utilise le plugin rails acts-as-taggable-on et j'essaie de trouver les 5 balises les plus utilisées dont les noms correspondent et correspondent partiellement à une requête donnée.

Quand je User.skill_counts.order('count DESC').limit(5).where('name LIKE ?', params[:query])

Ce retour l'erreur suivante:

ActiveRecord::StatementInvalid: SQLite3::SQLException: ambiguous column name: name: SELECT  tags.*, COUNT(*) AS count FROM  "tags" INNER JOIN users ON users.id = taggings.taggable_id LEFT OUTER JOIN taggings ON tags.id = taggings.tag_id AND taggings.context = 'skills' WHERE  (taggings.taggable_type = 'User') AND (taggings.taggable_id IN(SELECT  users.id FROM  "users")) AND (name LIKE 'asd') GROUP BY tags.id, tags.name HAVING COUNT(*) > 0 ORDER BY count DESC LIMIT 5 

Mais quand je fais User.skill_counts.first.name

ce retour

"alliteration" 

J'apprécierais toute aide cette question.

Answer 1

tour de requête devrait ressembler à ceci

SELECT tags.*, COUNT(*) AS count FROM "tags" 
     INNER JOIN users ON users.id = taggings.taggable_id 
     LEFT OUTER JOIN taggings ON tags.id = taggings.tag_id AND taggings.context = 'skills' 
     WHERE (taggings.taggable_type = 'User') AND 
       (taggings.taggable_id IN(SELECT users.id FROM "users")) AND 
       (tags.name LIKE 'asd') 
     GROUP BY tags.id, tags.name HAVING COUNT(*) > 0 
     ORDER BY count DESC 
     LIMIT 5 

Pour cette Essayez suivante

User.skill_counts.order('count DESC').limit(5).where('tags.name LIKE ?', params[:query])
