Question

我的node.js api使用sequelize.js时出现问题。在特定的端点，我试图在一个表中插入一行，似乎一切正常但是一段时间（1小时-24小时后），当我试图创建行时，我收到错误：

错误：ER_NO_DEFAULT_FOR_FIELD：字段＆＃39; user_id＆＃39;没有默认值

原因是生成的查询尝试插入空值 insert into company_users (user_id,company_id)values()。我检查了我试图插入断点的数据，一切都很好。如果我重新启动api所有似乎都工作正常，但几个小时后再次出现相同的问题。我想提一下，问题只出现在这个端点，此端点也创建用户，添加用户分支，添加用户设置，adduser角色，最后在公司用户处添加用户。

router.post('/Users',jsonParser, function(req,res,next){

var newData = req.body;
if(newData.username){
    newData.username=null;
}
if(newData.password||newData.password!==""){
    newData.password = crypto.createHash('md5').update(newData.password).digest('hex');
}else{
    delete newData.password;
}
models[req.domainURL].sequelize.transaction(function (t) {
    var created_userID;
        return DB.createUser(req.domainURL, newData).then(function(results){
        created_userID=results.ID;
         var userbranchIds=newData.branchIDs.map(function(branchID){
             var userbranch={
                userID:created_userID,
                branchID:branchID
            };
            return userbranch;

      });

      return DB.addUserBranches(req.domainURL,userbranchIds);
  }).then(function(results){
        var usersettings = newData.userSettings.map(function(userSetting){

            var usersetting={
                settingID : userSetting.settingID,
                settingValue: userSetting.value,
                 userID:created_userID

         };


        return usersetting;

      });
      return DB.addUserUserSettings(req.domainURL,usersettings);

  }).then(function(results){
  return DB.addUserRole(req.domainURL,newData.RoleId,created_userID);


}).then(function(results){

///here there is the problem
      return DB.addCompanyUser(req.domainURL,req.decoded.companyId,created_userID);
  });
}).then(function(results){
res.send();


}).catch(function(error){

Errors.handleError(new Errors.SequelizeErrorWrapper(error,'User'),res);
 });


});



var CompanyUsers = sequelize.define('CompanyUsers',{
    companyID:
    {
        type: DataTypes.INTEGER(10).UNSIGNED, primaryKey: true, allowNull: false, field: 'company_id'
    },
    userID:
    {
        type: DataTypes.INTEGER(10).UNSIGNED, primaryKey: true, allowNull: false, field: 'user_id' 
    }
},
{
classMethods: {
    associate: function(models) {
        CompanyUsers.belongsTo(models.Companies, {foreignKey: 'companyID', targetKey: 'ID'});
        CompanyUsers.belongsTo(models.Users, {foreignKey: 'userID', targetKey: 'ID'});
    }
},
timestamps:false,
tableName: 'company_users',
freezeTableName: true
});
};


addCompanyUser: function(domain,company_id,created_user_id){
    var data={
            companyID:company_id,
            userID:created_user_id
        };

    return models[domain].CompanyUsers.create(data);
}

sequelize create（）生成无效的sql
