POMongoose: extending schemas
text
Body
copied!<p>Currently I have two almost identical schemas:</p> <pre><code>var userSchema = mongoose.Schema({ email: {type: String, unique: true, required: true, validate: emailValidator}, passwordHash: {type: String, required: true}, firstname: {type: String, validate: firstnameValidator}, lastname: {type: String, validate: lastnameValidator}, phone: {type: String, validate: phoneValidator}, }); </code></pre> <p>And</p> <pre><code>var adminSchema = mongoose.Schema({ email: {type: String, unique: true, required: true, validate: emailValidator}, passwordHash: {type: String, required: true}, firstname: {type: String, validate: firstnameValidator, required: true}, lastname: {type: String, validate: lastnameValidator, required: true}, phone: {type: String, validate: phoneValidator, required: true}, }); </code></pre> <p>Their only difference is in validation: Users do not need a firstname, lastname or phone. Admins however must have these properties defined.</p> <p>Unfortunately the above code is not very DRY, as they're almost identical. Therefore I am wondering if it is possible to build an <code>adminSchema</code> based on the <code>userSchema</code>. E.g.:</p> <pre><code>var adminSchema = mongoose.Schema(userSchema); adminSchema.change('firstname', {required: true}); adminSchema.change('lastname', {required: true}); adminSchema.change('phone', {required: true}); </code></pre> <p>Obviously that's just pseudocode. Is something like this possible?</p> <p>Another very similar question is if it is possible to create a new schema based on another, and add some more properties to it. For example:</p> <pre><code>var adminSchema = mongoose.Schema(userSchema); adminSchema.add(adminPower: Number); </code></pre>
