La validation de Gif a échoué: aime: Cast to Array a échoué pour la valeur "1" au chemin "aime"

Question

Je rencontre des difficultés lors de l'enregistrement de certaines données dans la base de données mongoose. Vous pouvez trouver toutes les informations de mon modèle et contrôleur. Le problème est que je veux garder un tableau d'utilisateurs qui ont aimé un poste spécifique, donc je tiens leur ObjectId dans le tableau, plus j'ai spécifié dans le modèle comme [{ type: Schema.Types.ObjectId, ref: 'User' }].

je me connecte avant et après la manipulation des données et il me donne la sortie désirée:

The likes value of the found gif: [] 
Document Id is: 59c3122632af313ff3a9d962 
User not liked yet! 
New likes value: ["59c3122632af313ff3a9d962"] 

, il dit encore me donner l'erreur de validation suivant:

ValidationError: Gif validation failed: likes: Cast to Array failed for value "1" at path "likes" 

apprécierait si vous souligner ce qui ne va pas dans mon code. Meilleur!

Voici mon contrôleur:

export function handleLike(req, res) { 
    // We will need the uid of the liking user and cuid of the liked gif 
    Gif.findOne({ cuid: req.body.cuid }).exec((err, gif) => { 
    if (err) { 
     res.status(500).send(err) 
     console.log('Error while the gif is being found.') 
    } 
    console.log('The likes value of the found gif: ', gif.likes) 
    User.findOne({ uid: req.body.uid }).exec((e, user) => { 
     if (e) { 
     res.status(500).send(err) 
     console.log('Error while user is being found.') 
     } 
     const userDocumentId = user._id 
     console.log('Document Id is: ', userDocumentId) 
     const isUserLiked = gif.likes.includes(userDocumentId) 
     console.log('User not liked yet!') 
     if (isUserLiked) { 
     const newLikeArray = gif.likes.filter(like => like !== userDocumentId) 
     gif.set({ likes: newLikeArray }) 
     } else { 
     const newLikeArray = gif.likes.push(userDocumentId) 
     gif.set({ likes: newLikeArray }) 
     } 
     console.log('New likes value: ', gif.likes) 
     gif.save((error, newGif) => { 
     console.log(gif) 
     if (error) { 
      res.status(500).send(error) 
      console.log('Error while saving the gif.') 
      console.log(error) 
     } 
     res.send(newGif) 
     }) 
    }) 
    }) 
} 

Voici mon modèle:

const GifSchema = Schema({ 
    // In case there may occur a problem with Google Cloud Upload, make URL required! 
    id: { type: String, required: true }, 
    crop_start: { type: Number, required: true }, 
    crop_finish: { type: Number, required: true }, 
    meme: String, 
    tags: [String], 
    url: { type: String }, 
    cuid: { type: 'String' }, 
    uploaded: { type: Date, default: Date.now }, 
    disabled: { type: Boolean, default: false }, 
    likes: [{ type: Schema.Types.ObjectId, ref: 'User' }], 
    owner: { type: Schema.Types.ObjectId, ref: 'User' }, 
    customWidth: Number, 
    customHeight: Number, 
}) 

Et la sortie de la console et l'erreur est telle qu'indiquée ci-dessous:

The likes value of the found gif: [] 
Document Id is: 59c3122632af313ff3a9d962

Answer 1

Vous passez le mauvais argument, comme si vous utilisiez les réactions de setState:

gif.set({ likes: newLikeArray }) 

Selon le API, vous devriez passer le path et value séparément:

Document#set(path, val, [type], [options]) 

Sets the value of a path, or many paths.
Parameters:
path path or object of key/vals to set
val the value to set
[type] optionally specify a type for "on-the-fly" attributes
[options] optionally specify options that modify the behavior of the set

soit utiliser:

gif.set('likes', newLikeArray) 

ou:

gif.likes = newLikeArray
