我試圖添加一個新的設計模型。當我使用sign_up路徑時,我可以創建一個用戶,但在保存新用戶(醫生)後會拋出一個錯誤。這個錯誤並不是很有幫助,所以我希望有人能指出我正確的方向進行調試。Rails Devise PG :: SyntaxError:ERROR:零長度分隔標識符位於或接近「」「」
的錯誤是ActiveRecord::StatementInvalid in Devise::RegistrationsController#create
PG::SyntaxError: ERROR: zero-length delimited identifier at or near """" LINE 1: ...in_ip" = $4, "sign_in_count" = $5 WHERE "doctors"."" IS NULL^: UPDATE "doctors" SET "current_sign_in_at" = $1, "current_sign_in_ip" = $2, "last_sign_in_at" = $3, "last_sign_in_ip" = $4, "sign_in_count" = $5 WHERE "doctors"."" IS NULL
我的模式是
create_table "doctors", id: false, force: true do |t|
t.string "email", default: "", null: false
t.string "encrypted_password", default: "", null: false
t.string "reset_password_token"
t.datetime "reset_password_sent_at"
t.datetime "remember_created_at"
t.integer "sign_in_count", default: 0, null: false
t.datetime "current_sign_in_at"
t.datetime "last_sign_in_at"
t.string "current_sign_in_ip"
t.string "last_sign_in_ip"
end
add_index "doctors", ["email"], name: "index_doctors_on_email", unique: true, using: :btree
add_index "doctors", ["reset_password_token"], name: "index_doctors_on_reset_password_token", unique: true, using: :btree
我應該在哪裏尋找調試呢?我試圖調試設備控制器,但我找不到它。
謝謝。
生成的查詢' WHERE「醫生」。「」IS NULL「這是postgres中無效的語法。有關錯誤的說明,請參閱http://stackoverflow.com/questions/23165282/error-zero-length-delimited-identifier-at-or-near-line-1-delete-from-reg#comment35439475_23165282。 –
