JavaScript Retrieving Entries from a Table

findAll is not a function.

Hello,

I tried to implement this in an application I'm building myself but seemed to have run into an issue. I'm trying to retrieve all vacancies in my database. There is 1 in there.

In my routing file, I have:

    const Vacancy = require("../models/vacancy");

// GET /vacancies
app.route("/vacancies").get((req, res) => {
    Vacancy.findAll().then(vacancies => {
        res.render("vacancies", { vacancies: vacancies });
    });
});

In my model file:

"use strict";

module.exports = (sequelize, DataTypes) => {
    const Vacancy = sequelize.define("Vacancy", {
        title: DataTypes.STRING,
        description: DataTypes.STRING,
        releaseDate: DataTypes.DATE,
        isActive: DataTypes.BOOLEAN,
        weWant: DataTypes.STRING,
        weSearch: DataTypes.STRING,
        applicationEmail: DataTypes.STRING,
    }, {});

    Vacancy.associate = models => {
        Vacancy.belongsTo(models.Company, {
            foreignKey: {
                name: "companyId",
            },
        });

        Vacancy.belongsTo(models.STA_JobType, {
            foreignKey: {
                name: "jobTypeId",
            },
        });

        Vacancy.belongsTo(models.STA_Industry, {
            foreignKey: {
                name: "industryId",
            },
        });

        Vacancy.belongsTo(models.STA_ExperienceRange, {
            foreignKey: {
                name: "experienceRangeId",
            },
        });

        Vacancy.belongsTo(models.STA_Workspace, {
            foreignKey: {
                name: "workspaceId",
            },
        });

        Vacancy.belongsToMany(models.Location, {
            through: "VacancyLocation",
            foreignKey: {
                name: "locationId",
            },
        });
    };

    return Vacancy;
};

When going to the route, I receive this error:

   {"err":"TypeError occured. See the stack for more information.","stack":["TypeError: Vacancy.findAll is not a function","    at app.route.get (C:\\ST\\CJ\\server\\routes\\index.js:39:11)"," ...

Might you have a clue?

Thanks.

In your routing file, is your require statement closed properly? in your shared snippet, it looks like you left off the closing bits.

    const Vacancy = require("../models/vaca  // notice here the lack of closing quotes or parentheses

// GET /vacancies
app.route("/vacancies").get((req, res) => {
    Vacancy.findAll().then(vacancies => {
        res.render("vacancies", { vacancies: vacancies });
    });
});

Joseph Wasden Sorry, mate. Unfortunately that's a copy paste mistake into here. :D It's actually like this in my file:

const Vacancy = require("../models/vacancy");

You probably found a solution already, but could it be that your require statement does not have the Vacancy method appended to it? i.e.

const Vacancy = require("../models/vacancy").Vacancy;

Since findAll() is a built in ORM classMethod, it should work with your implementation.

I'm just going by what we've seen so far with this course, in there we have

var Article = require("../models").Article;
