无法添加外键约束errno：1215 sequlize / mysql

如何解决无法添加外键约束errno：1215 sequlize / mysql

所以。我正在创建表，并且在迁移时遇到错误：

无法添加外键约束

errno: 1215
sqlState: 'HY000',sqlMessage: 'Cannot add foreign key constraint',sql: 'CREATE TABLE IF NOT EXISTS users_questionnaire_contact\n' +
  "    (   user_id int(10) unsigned NOT NULL DEFAULT '0',\n" +
  "        del int(10) unsigned NOT NULL DEFAULT '0',\n" +
  "        id_questionnaire int(10) unsigned NOT NULL DEFAULT '0',\n" +
  "        contact char(1) COLLATE 'utf8_general_ci' NOT NULL DEFAULT '1',\n" +
  '        createdAt datetime NOT NULL DEFAULT CURRENT_TIMESTAMP,\n' +
  '        updatedAt datetime NOT NULL DEFAULT CURRENT_TIMESTAMP,\n' +
  '        CONSTRAINT FK_UQContactUser FOREIGN KEY (user_id) REFERENCES users(id) ON DELETE CASCADE,\n' +
  '        FOREIGN KEY (id_questionnaire) REFERENCES questionnaires(id),\n' +
  '        PRIMARY KEY (user_id,id_questionnaire)\n' +
  '    ) ENGINE=InnoDB DEFAULT CHARSET=utf8;'

}，

我正在使用sequlize.js orm和sequlize：cli进行迁移。这是我出现错误的模型表格。

module.exports = function(sequelize,DataTypes) {
  return sequelize.define('UserQuestionnaireContact',{
    user_id: {
      type: DataTypes.INTEGER(10).UNSIGNED,allowNull: false,defaultValue: '0',primaryKey: true
    },id_questionnaire: {
      type: DataTypes.INTEGER(10).UNSIGNED,contact: {
      type: DataTypes.CHAR(1),defaultValue: '1'
    }
  },{
    tableName: 'users_questionnaire_contact',defaultScope: { attributes: { exclude: [ 'id'] } }
  });
};

我的用户模型：

  module.exports = function(sequelize,DataTypes) {
  const Model = sequelize.define('User',{
      company_id: {
        type: DataTypes.INTEGER(10).UNSIGNED,references: {
          model: 'Company',key: 'id'
        }
      },first_name: {
        type: DataTypes.STRING(512),allowNull: false
      },last_name: {
        type: DataTypes.STRING(250),allowNull: true
      },career_category_id: {
        type: DataTypes.INTEGER(10),training_course_id: {
        type: DataTypes.INTEGER(11),country_id: {
        type: DataTypes.INTEGER(11),currency_id: {
        type: DataTypes.INTEGER(11),},{
      tableName: 'users'
    });

    Model.associate = models => {
      Model.belongsTo(models.Currency,{foreignKey: 'currency_id',as: 'curr'});
      Model.belongsTo(models.Country,{foreignKey: 'country_id',as: 'country'});
      Model.belongsTo(models.CareerCategory,{foreignKey: 'career_category_id',as: 'career'});
      Model.belongsTo(models.TrainingCourse,{foreignKey: 'training_course_id',as: 'training_course'});
      Model.belongsTo(models.Company,{foreignKey: 'company_id',as: 'company'});
      Model.hasMany(models.Attempt,{foreignKey: 'user_id',as: 'attempts'});
      Model.hasMany(models.UserQuestionnaireContact,as: 'u_q_contact'});
      Model.hasMany(models.UsersQuestionnaireAttemptLimit,as: 'u_q_limit'});
    };

  return Model;
};

与我有关的问题表：

 const Model = sequelize.define('Questionnaire',{
    type: {
      type: DataTypes.INTEGER(10).UNSIGNED,allowNull: true,defaultValue: '0'
    },{
    tableName: 'questionnaires'
  });

  Model.associate = models => {
    Model.belongsToMany(models.Company,{
      as: 'questCompanies',foreignKey: 'questionnaire_id',otherKey: 'company_id',through: 'company_questionnaire_maps'});
    Model.hasMany(models.Attempt,{foreignKey: 'questionnaire_id',as: 'q_attempts'});
    Model.hasMany(models.QuestionGroup,as: 'q_groups'});
    Model.hasMany(models.CompanyQuestionnaireMap,as: 'company_questionnaire_maps'});
  };

有人知道如何解决此问题吗？预先感谢。
