Simple Schema

Un package qui va vraiment vous faciliter la vie !!!

En résumer, simple-schema vous permet de définir la structure de chaque Collection ou d'un simple formulaire.

Mais le plus important est que la validation est utilisable autant coté client que coté serveur.

Exemple:

BookSchema = new SimpleSchema({
  title: {
    type: String,
    label: "Title",
    max: 200
  },
  author: {
    type: String,
    label: "Author"
  },
  copies: {
    type: Number,
    label: "Number of copies",
    min: 0
  },
  lastCheckedOut: {
    type: Date,
    label: "Last date this book was checked out",
    optional: true
  },
  summary: {
    type: String,
    label: "Brief summary",
    optional: true,
    max: 1000
  }
});

SimpleSchema.extendOptions({
  editable: Match.Optional(Boolean)

MessageSchema = new SimpleSchema({
  body: {
    type: String,
    editable: true
  },
  createdAt: {
    type: Date
  },
  userId: {
    type: String
  }
});

var whitelist = _.filter(_.keys(MessageSchema), function (property) {
  return MessageSchema[property].editable;
});

Messages.allow({
  update: function (userId, doc, fields, modifier) {
    if (userId && doc.userId === userId && _.difference(fields, whitelist).length === 0) {
      return true;
    }
  }
});
