| carrierwaveの画像投稿で、画像データがDBに登録されない（インスタンス変数に代入されない） |
| ## 困っていること |
| carrierwave + mini_magick + deviseを用いてユーザー登録時にアバター画像を投稿できるようにしたいです。 |
| 長文となり恐れ入りますが、アドバイス頂ければ幸いです。よろしくお願いいたします。 |
| ## 課題に対するアクション |
| - binding.pryを用いたデバッグ |
| ① ストロングパラメーターのうち、[:avatar]のみインスタンス変数@profileに渡っていないように見える |
| ``` |
| [1] pry(#<Users::RegistrationsController>)> @profile |
| => #<Profile:0x00007fb1b7dd95a8 |
| id: nil, |
| phonenumber: "1118883333", |
| old: 21, |
| job: 1, |
| experience: 1, |
| practice_time: 1, |
| detail: "よろしく", |
| club: "ホゲホゲ", |
| avatar: nil, //問題点。なぜかnil |
| user_id: nil, |
| created_at: nil, |
| updated_at: nil> |
| ``` |
| ②ストロングパラメーターは適切なデータを受け取っていると考えられる |
| ``` |
| => <ActionController::Parameters {"phonenumber"=>"1118883333", "old"=>"21", "job"=>"1", "experience"=>"1", "practice_time"=>"1", "detail"=>"よろしく", "club"=>"ホゲホゲ", "avatar"=>#<ActionDispatch::Http::UploadedFile:0x00007fb1b7de7888 @tempfile=#<Tempfile:/var/folders/l9/g98ryfjs4730gx0slq67713r0000gn/T/RackMultipart20200718-27218-1f1z01b.png>, @original_filename="7071b4262c632dc0e7c7660f15459fba.png", @content_type="image/png", @headers="Content-Disposition: form-data; name=\"profile[avatar]\"; filename=\"7071b4262c632dc0e7c7660f15459fba.png\"\r\nContent-Type: image/png\r\n">} permitted: true> |
| ``` |
| ③@profile.avatarでは画像データが代入されている |
| ``` |
| => #<AvatarUploader:0x00007fb1b7dcaff8 |
| @cache_id="1595048033-27925243257579-0005-8319", |
| @cache_storage=#<CarrierWave::Storage::File:0x00007fb1b7dc2b28 @cache_called=nil, @uploader=#<AvatarUploader:0x00007fb1b7dcaff8 ...>>, |
| @file= |
| #<CarrierWave::SanitizedFile:0x00007fb1b7dc9b58 |
| @content=nil, |
| @content_type="image/png", |
| @file="/Users/teranishiyusuke/projects/badsuru/public/uploads/tmp/1595048033-27925243257579-0005-8319/7071b4262c632dc0e7c7660f15459fba.png", |
| @original_filename="7071b4262c632dc0e7c7660f15459fba.png">, |
| @filename="7071b4262c632dc0e7c7660f15459fba.png", |
| @identifier=nil, |
| @model= |
| #<Profile:0x00007fb1b7dd95a8 |
| id: nil, |
| phonenumber: "1118883333", |
| old: 21, |
| job: 1, |
| experience: 1, |
| practice_time: 1, |
| detail: "よろしく", |
| club: "ホゲホゲ", |
| avatar: nil, |
| user_id: nil, |
| created_at: nil, |
| updated_at: nil>, |
| @mounted_as=:avatar, |
| @original_filename="7071b4262c632dc0e7c7660f15459fba.png", |
| @staged=true, |
| @versions={}> |
| ``` |
| ④avatarがnilだからか、@user.save時に、avatarに対するSQL文が発行されていないように見える |
| ``` |
