问题 I have Video model: module.exports = { attributes: { id: 'string', tags: 'array' }, } I want to find all videos with tags for example "Hello" or "World". I could easy get all videos like: Video.find({tags:"Hello"}). I saw examples where searching id: [1,2,3] but not when key(id => tags) is array. 回答1: Use the "in"-Statement in combination with "contains" Video.find({tags: { contains: ["some1","some2"]}}).exec(function(err,res){ console.log(res); }); See: https://github.com/balderdashy

问题 Are there a good way to get async data from an EJS file? Sails.js only have async methods to get data from a database. I have a collection of Pages with their associated content Values . In some cases I want to get a specific Value from another Page (e.g.: in a related page module, a navigation module...). And I need to do that server side , to keep the front-end part SEO friendly . The easier way should be to retrieve all the Pages and Values inside the controller, and then expose a function

问题 Newbie question here. According to https://github.com/balderdashy/waterline#indexing you cannot use a 'string' datatype as an index in Waterline due to issues with case insensitivity: There is currently an issue with adding indexes to string fields. Because Waterline performs its queries in a case insensitive manner, we are unable to use the index on a string attribute. There are some workarounds being discussed but nothing is implemented so far. This will be updated in the near future to

问题 Using waterline.js in sails.js (0.10.5): I would like to create a 'where' string out of a where option object. For example, I have: where = { updatedAt:{">":"2015-01-08T10:00:00.000Z","<=":"2015-01-08T20:00:00.000Z"} }; and I would like to have a generated string (similar to): "WHERE updatedAt > '2015-01-08T10:00:00.000Z' AND updatedAt <= '2015-01-08T20:00:00.000Z'" Is this possible? I have the feeling it should be... 回答1: You can do date range queries using the comparison operators. Model

问题 I have two models (user & agent). I then create a user and an agent. I am expecting to see the association when using the blueprint routes for BOTH /user and /agent. I am only seeing the user model is associated with an agent via the /agent blueprint. The /user blueprint does not have any reference/association to an Agent. The issue presents itself when I am trying to access the Agent via A userId with the following command: User.findOne(req.body.userId).populate('agent').exec(function(err,

问题 I'm trying to add some auditing capability to my sails.js app. The afterUpdate lifecycle callback will give me the proper place to do what I need, but I'm hoping to avoid modifying every model to reference my new code. Is there a way to specify an afterUpdate callback that will fire on all models? 回答1: Put your required overrides into config/models.js module.exports.models = { attributes: {}, afterUpdate: function (valuesToUpdate, cb) { // add your logic here... console.log('yep, updated');

问题 In sails.js, Models support lifecycle callbacks for validate, create, update and destroy. Is there support for callbacks for find() or query as well? Like beforeFind() and afterFind()? The idea is same. I would want to validate / modify parameters before the query is run or after the query is run. Any thoughts? 回答1: As of writing this it does NOT support these requests, however their is a pull request https://github.com/balderdashy/waterline/pull/525 You can use policies to do this in the

问题 Trying to delete a user model using: //Hard Delete User.destroy({id:userId}, function(err, res){ //Hard Delete }) I need to do a soft delete on User model and currently setting a flag isDeleted to true on delete and updating document: updateUser.isDeleted = true; User.update({id:userId}, updateUser, function(err, res){ Update project }) and while fetching documents I am doing a check If isDeleted - true or not. Is there any In-built feature provided by Sails or Waterline which I can configure

问题 Using Sails.js version 0.10.x , assume I have a model Dog , populated as follows (writtenout in yaml format for convenience, but in my case it's actually in a mongo database.) dogs: - breed: "wolf" name: "Fido" - breed: "wolf" name: "Roger" - breed: "dingo" name: "Nipper" - breed: "dingo" name: "Ernie" - breed: "corgi" name: "Bernadi" - breed: "corgi" name: "Queenie" - breed: "poodle" name: "Christopher" - breed: "poodle" name: "Tony" etc So now I want to create a list of the available breeds

问题 So I have a model with some fields like so: // ... slug: { type: 'string', required: true, alphanumeric: true, minLength: 3, maxLength: 16 }, loggedinAt: 'date', // ... I'm using the Sails blueprint structure so it automatically maps everything. However, sometimes I have fields like loggedinAt which are strictly internal and I don't want them to be able to be set by the user. As it stands if I make a post requests with the loggedinAt field it will set it. How can I restrict this? 回答1: You can
