如何向SQL查询添加AND条件

我试图添加一个AND条件，其中

active=true

也包含在rails内部的SQL查询中

Schema.rb

...
create_table 'relationships', force: :cascade do |t|
    t.integer  'follower_id'
    t.integer  'followed_id'
    t.datetime 'created_at',                 null: false
    t.datetime 'updated_at',                 null: false
    t.boolean  'active', default: true
    t.index ['followed_id'], name: 'index_relationships_on_followed_id'
    t.index %w[follower_id followed_id], name: 'index_relationships_on_follower_id_and_followed_id', unique: true
    t.index ['follower_id'], name: 'index_relationships_on_follower_id'
  end
...

...
def feed
 following_ids = "SELECT followed_id FROM relationships
                  WHERE follower_id = :user_id AND active = true"
                     
  View.where("user_id IN (#{following_ids})
         OR user_id = :user_id", user_id: id).includes(:user)
 end
...

user.rb

...
create_table 'relationships', force: :cascade do |t|
    t.integer  'follower_id'
    t.integer  'followed_id'
    t.datetime 'created_at',                 null: false
    t.datetime 'updated_at',                 null: false
    t.boolean  'active', default: true
    t.index ['followed_id'], name: 'index_relationships_on_followed_id'
    t.index %w[follower_id followed_id], name: 'index_relationships_on_follower_id_and_followed_id', unique: true
    t.index ['follower_id'], name: 'index_relationships_on_follower_id'
  end
...

...
def feed
 following_ids = "SELECT followed_id FROM relationships
                  WHERE follower_id = :user_id AND active = true"
                     
  View.where("user_id IN (#{following_ids})
         OR user_id = :user_id", user_id: id).includes(:user)
 end
...

但是，添加

和active=TRUE

似乎无法将

跟随id

和

跟随id

作为

self

，其中

active

布尔值为

TRUE

通过在查询中分配

active

来解决它

...
def feed
 following_ids = "SELECT followed_id FROM relationships
                  WHERE follower_id = :user_id AND active = :active"
                     
  View.where("user_id IN (#{following_ids})
         OR user_id = :user_id", user_id: id, active: true).includes(:user)
 end
...
