Sequelize :: Limit and Order INSIDE an Include[] construct

由 可紊 提交于 2019-12-06 22:55:54
问题 I have the following model hierarchy: User.hasMany(Child); Child.hasMany(Profile); Once I have a User object loaded, I need to load its Children and their associated Profiles according to the following logic: Load all Children for the User , sorted by name . For each Child , load the first three Profiles reverse sorted by id . Is there a way to limit and sort the eager-loaded Profiles ? I can limit and sort the Children but not the Profiles . user.getChildren({ limit: 10, order: [['name',

Remove constraints in sequelize migration

由 为君一笑 提交于 2019-12-06 19:30:01
问题 I'm adding a unique constraint in a migration via the migrations.changeColumn function. Adding the constraint works, but since you need to provide a “backwards migration“, removing it the same way does not. It doesn't give any errors when migrating backwards, but again applying the forward migration results in Possibly unhandled SequelizeDatabaseError: relation "myAttribute_unique_idx" already exists . (The used database is postgres) module.exports = { up: function (migration, DataTypes, done

Sequelize belongsToMany additional attributes in join table

由 最后都变了- 提交于 2019-12-06 15:05:22
I'm having problem with an additional attribute in the join table of the belongsToMany relation. In the set or add method this attribute is not being passed to mysql. I'm following the documentation pass as "through" the attribute within the set method, but it is not working. Would anyone know what could be wrong since following the documentation is not working? Note: The registration and update of the join is correct, only the additional attribute that is not being passed to the table.

Sequelize - How to get a list of nested table entries (Project -> Task through Milestones)?

由 自作多情 提交于 2019-12-06 14:37:34
Lets say I have the tables User, Project, Milestone, Task User.belongsToMany(Project, {through: ProjectUser}) Project.belongsToMany(User, {through: ProjectUser}) Project.hasMany(Milestone) Milestone.belongsTo(Project) Milestone.hasMany(Task) Task.belongsTo(Milestone) Now I can easily get all Milestones in a Project where a User belongs to: User.findAll({ include: [{ model: Project, include: [{ model: Milestone include: [ Task ] }] }] Now I would like to get the Tasks not inside the Milestones. Instead I would like to get the Tasks parallel to Milestones. Like this: User.findAll({ include: [{

问题 I am attempting to create an instance and multiple related instances with a many to many relation using a junction table. While creating the multiple related instances, I need to add a value to a property on the junction table as well. I don't know if it is my lack of knowledge of sequelize or promises that is causing my problem. The code I am using is below. This code does add the items to the database, but I need to redirect after the operation has completed, which is not working. Basically

问题 I'm using Sequelize with MySQL. When I run this code: usuarioService.getAll = function () { Usuario.findAll().then(function (users) { //return users; console.dir(users); }); } Instead of get the user, I get: http://i.stack.imgur.com/uLhmN.png Help me, please!
