sails-hook-parsequery
A helper to parse request queries and params based on Sails Blueprints actions.
How to use
- Parse a filter from query and params (inputs).
- Process an action with the processed filter.
Filter
Action:
- 'add',
- 'create'
- 'destroy'
- 'find'
- 'findOne'
- 'populate'
- 'remove'
- 'replace'
- 'update'
// api/controllers/some/action.js
...
fn: function(inputs, exits) {
const model = 'user';
const action = 'find';
const filter = sails.helpers.parse.query(model, action, this.req.query, inputs);
// ...
}
Action
// api/controllers/some/action.js
...
fn: function(inputs, exits) {
const model = 'user';
const action = 'find';
const filter = sails.helpers.parse.query(model, action, this.req.query, inputs);
const res = sails.helpers.actions[action](filter);
return this.res.ok({list: res.list, count: res.count});
}
Error Handler
Use intercept/tolerate:
// api/controllers/some/action.js
...
fn: function(inputs, exits) {
const model = 'user';
const action = 'find';
const filter = sails.helpers.parse.query(model, action, this.req.query, inputs)
.intercept('badRequest', 'badRequest')
.intercept('notFound', 'notFound');
const res = sails.helpers.actions[action](filter)
.intercept('notFound', 'notFound');
return this.res.ok({list: res.list, count: res.count});
}
or use try/catch:
// api/controllers/some/action.js
...
fn: function(inputs, exits) {
const model = 'user';
const action = 'find';
try {
const filter = sails.helpers.parse.query(model, action, this.req.query, inputs);
const res = sails.helpers.actions[action](filter);
return this.res.ok({list: res.list, count: res.count});
} catch (err) {
sails.log.error(err);
throw 'badRequest';
}
}
