问题 I am using sequelize as my backend ORM. Now i wish to do some where operations on a Date. More Speceficly i want to get all data where a date is from now and 7 days back.

问题 This is one thing that really annoys me! I have to write 2 different functions for almost the same query! Say I've got an API that returns posts that are associated to a particular typeId and cityId . To get ALL posts that are associated to typeId 1 OR 2, OR 3 and cityId 1 I would parse the following to my sequelize findAll query: $or: [{typeId: 1}, {typeId: 2}, {typeId: 3}] cityId: 1 But say I want to get all post where cityId = 1 andOr typeId = 1,2,3,4,5,6,7,8,9,10,etc... I cannot do

问题 I have a given database with long, cumbersome columnnames. Isn't there any way to map the tablenames to shorter and more descriptive propertyNames in the model ? something like var Employee = sql.define('Employee', { id : {type : Sequelize.INTEGER , primaryKey: true, map : "veryLongNameForJustTheId"} },{ tableName: 'cumbersomeTableName', timestamps: false });; 回答1: id : { field: 'some_long_name_that_is_terrible_thanks_dba_guy', type : Sequelize.INTEGER , primaryKey: true } Specify a 'field'
