Sequelize Error: Relation does not exist

Question

I am able to use sequelize.js to do an INSERT INTO command for a table in my development database, but not in my test database.

Despite researching thoroughly, I have not been able to resolve the issue.

A similar question has been posted here, though I have not been able to answer my question with the answers: sequelize with postgres database not working after migration from mysql

Here is my relevant migration file:

'use strict';
module.exports = {
  up: (queryInterface, Sequelize) => {
    return queryInterface.createTable('Trees', {
      id: {
        allowNull: false,
        autoIncrement: true,
        primaryKey: true,
        type: Sequelize.INTEGER
      },
      title: {
        type: Sequelize.STRING,
        allowNull: false
      },
      content: {
        type: Sequelize.STRING(10000),
        allowNull: false
      },
      createdAt: {
        allowNull: false,
        type: Sequelize.DATE
      },
      updatedAt: {
        allowNull: false,
        type: Sequelize.DATE
      }
    });
  },
  down: (queryInterface, Sequelize) => {
    return queryInterface.dropTable('Trees');
  }
};

Here is the model file:

'use strict';
module.exports = (sequelize, DataTypes) => {
  var Tree = sequelize.define('Tree', {
    title: {
      type: DataTypes.STRING,
      allowNull: false
    },
    content: {
      type: DataTypes.STRING(10000),
      allowNull: false
    }
  }, {});
  Tree.associate = function(models) {
    // associations can be defined here
  };
  return Tree;
};

Here is the code that accesses the database:

const setTree = (treeVal, callback) => {
  console.log(`this would be the part`);
  Tree.create({
    title: 'Tree',
    content: JSON.stringify(treeVal)
  })
  .then((treeStr) => {
    let primaryTopics = JSON.parse(treeStr.content);
    callback(null, primaryTopics);
  })
  .catch((err) => {
    callback(err);
  });
}

This is exported in the module.exports method:

  callTree(callback) {
    return Tree.findOne({
      where: {
        title: 'Tree'
      }
    })
    .then((treeStr) => {
      if (treeStr === null) {
        return callback(`not defined yet`);
      }
      let primaryTopics = treeStr.content;
      primaryTopics = JSON.parse(primaryTopics);
      callback(null, primaryTopics);
    })
    .catch((err) => {
      callback(err);
    });
  }

And I'm pulling this method for an integration test here (the PrimaryTopic table is in the same database, and I receive no errors trying to run it):

  beforeEach((done) => {
    this.primaryTopic;
    sequelize.sync({force: true}).then((res) => {

      PrimaryTopic.create({
        title: 'Title: Hello World',
        content: '<p>Content: Hello World</p>'
      })
      .then((primaryTopic) => {
        this.primaryTopic = primaryTopic;
        treeQueries.buildTree((err, res) => {
          if (err) {
            console.error(err);
          }
        });
        done();
      })
      .catch((err) => {
        console.log(err);
        done();
      });

    });
  });

I've searched through all the code for possible errors, but haven't found anything yet.

I can use psql to access the Trees table in the test database, though it is empty.

I can use the same code to insert a value into the Trees table in the development database with no issues.

Here is the error I receive when I try to run a test (using jasmine.js for testing):

Answer 1

I know this is old but it could help somebody else facing same issue. I migrated from mysql to postgres and got same issue because the name of my table started with upper case ("Home") and I was trying to add a constraint with table name "home" which starts with lowercase.
