获取 SQL 个不同的数据书架模型
Get SQL distinct data Bookshelf Model
我正在尝试通过书架模型从 MySQL 数据库中获取不同的数据。
部门主管:
Department.distinct('departmentName').fetchAll().then((result) => {
return res.send({
status: '204',
message: 'Data is Fetched',
error: false,
data: result
})
}
部门模型:
Bookshelf.model('Department' , {
tableName:'departments',
hasSecurePassword: true,
hasTimestamps : ['created_at' , 'updated_at'],
softDelete: true,
hidden: ['deleted_at'],
parse: function(response){
if(response.allowUseOfMyContactInformation != null)
response.allowUseOfMyContactInformation = !!+response.allowUseOfMyContactInformation;
return response;
}
})
有人请帮助我遇到错误"Department.distinct is not a function"
问题是您正在尝试对模型而不是 Department 模型的对象进行查询。
对您的部门控制器进行更改
首先,您需要在部门控制器中导入部门模型
const Department = require('your Department model path');
const department = new Department();
department.distinct('departmentName').fetchAll().then((result) => {
return res.send({
status: '204',
message: 'Data is Fetched',
error: false,
data: result
})
希望对您有所帮助。如果您有任何问题,请告诉我。
经过漫长的google。我发现查询 groupBy 救了我的命:
dashboard_department = (req, res) => {
try {
Department.query({
groupBy: 'departmentName'
}).fetchAll().then((result) => {
return res.send({
status: '204',
message: 'Data is Fetched',
error: false,
data: result
})
}).catch((error) => {
return res.send({
status: '404',
message: 'Data is not fetched',
error: true,
data: {}
})
})
} catch (e) {
return res.send({
status: '404',
message: 'Internal Server Error',
error: true,
data: {}
})
}
}
