【问题描述】：
我有两个架构 UserSchema 和 RoleTypeSchema 。在UserSchema 中，我添加了一个字段UserRoleType，即ref RoleTypeSchema。我要做的是在RoleTypeCollection 中创建roleType，然后当我在UserCollection 中创建UserObject 时，我可以在UserCollection 中看到UserRoleType 字段。
The error that i am getting is after i create the role and user, when i get an error validation:
THE ERROR
{"message":"userSchema validation failed: usersRoles: Path `usersRoles` is required."}
UserSchema
//requiring the mongoose module
const mongoose = require('mongoose');
// create the schema
var userSchema = new mongoose.Schema({
//creating the attributes/ data of the schema
username: {
type: String,
required: true
},
password: {
type: String,
required: true
},
usersRoles: {
type: mongoose.Schema.Types.ObjectId,
ref: 'usersRolesSchema',
required: true
}
});
const userDB = mongoose.model('userSchema', userSchema);
module.exports = userDB;
RoleTypeSchema
//requiring the mongoose module
const mongoose = require('mongoose');
var usersRolesSchema = new mongoose.Schema({
userRole: {
type: String,
required: true
}
})
const userRolesModel = mongoose.model('usersRolesSchema', usersRolesSchema);
module.exports = userRolesModel;
Create A User Controller
exports.createUser = (req, res, next) => {
console.log('Post CREATE User /create-user');
// getting the request body
const username = req.body.username;
const userRole = req.body.userRole;
const password = req.body.password;
const password2 = req.body.password2;
// check the body request by using express validator
req.checkBody('username', 'UserName is required').notEmpty();
req.checkBody('userRole', 'userRole is required').notEmpty();
req.checkBody('password', 'Password is required').notEmpty();
req.checkBody('password2', 'UserName is required').equals(req.body.password);
// get the error if there are any
let errors = req.validationErrors();
//validation for duplicate values
if (errors) {
userSchema.findOne({ username: req.body.username })
.then(user => { //that's will give us the user and then i want to check if
if (user) {
//if there is an error so rerinder the templet
res.render('users/create_user.ejs', {
errors: errors //pass along the errors
}, console.log(errors));
}
});
} else {
let newUser = new userSchema({
username: username, // first is the attribute NAME of the model , second is the name value tag in the html file
userRole: userRole,
password: password
});
bycrypt.genSalt(10, function(err, salt) {
bycrypt.hash(newUser.password, salt, function(err, hash) {
if (err) {
//ERROR PAGE
console.log(err);
}
/// Hashing the password
newUser.password = hash;
newUser.save()
.then(data => {
if (err) {
console.log(err);
return;
} else {
req.flash('success', 'You successfully registered')
res.redirect('/halalMunchies/all-users');
}
})
.catch(err => {
res.status(500).send({
message: err.message || "Some error occured while creating a create operation"
});
});
});
});
}
};
Showing All Users Data, which here it should show the userType also
exports.allUsers = (req, res, next) => {
console.log('GET CREATE USERS /all-users');
userSchema.find().populate('usersRoles', 'userRole')
.then(data => {
res.render('users/users.ejs', { usersList: data });
console.log();
})
.catch(err => {
console.log(err);
})
};
The creating userForm, in this form i will select the userRole and i can use req.body to that name tag so i can use it and save it like a username or password input
<label> User Type: </label>
<select class="form-control form-control-sm" id="roles" name="userRole">
<option value="" selected data-default> Select Role </option>
<% roles.forEach(function (role) {%>
<option> <%= role.userRole %> </option>
<%})%>
</select>
