request body undefined, mongoose validation error on nested properties-CodePudding

I am working a nodejs/express/mongoose

My model:

const TodoSchema = new mongoose.Schema({
name: { type: String, required: ['Name is required'] },
},

});

Controller :

async function createTask(req, res) {
try {
    const task = new Todo({ name: req.body });
    console.log(req);
    console.log('Name check: ', req.name);
    const result = await task.save();
    console.log('check: ', task, result);
    // res.send('Task created: ', result);
    res.json({ msg: 'Task created', item: result });
} catch (error) {
    console.log('Task creation error:', error);
    return res.json({
        msg: error,
    });
}

}

My response in postman:

    "msg": {
    "errors": {
        "name": {
            "name": "ValidatorError",
            "message": "Name is required",
            "properties": {
                "message": "Name is required",
                "type": "required",
                "path": "name"
            },
            "kind": "required",
            "path": "name"
        }
    },
    "_message": "Todo validation failed",
    "name": "ValidationError",
    "message": "Todo validation failed: name: Name is required"
}

}

and for my logs, req.name is undefined, and req.body.

I saw the docs for mongoose validation, and the type keyword, and tried the recommendations, but nothing helped. What's up with my post endpoint?

CodePudding user response：

You have an error when You use required in Your mongoose Schema, You miss true argument. Here is my example =>

const mongoose = require("mongoose");

const TaskSchema = new mongoose.Schema({
  name: {
    type: String,
    required: [true, "You Must Provide name"],
    trim: true,
    maxlength: [23, "Maximum twenty characters"],
    minlength: [5, "Minimum four characters"],
  }
});

module.exports = mongoose.model("Task", TaskSchema);

CodePudding user response：

Maybe, you just don`t add middlewares to express.

app.use(express.json());
app.use(express.urlencoded({ extended: false }))
