I've come across an issue that I'm having difficulty solving. There are two issues both of which appear to be caused by race conditions.
1.) The drawPoll() function is getting executed before the this.poll.choices are done appending. I confirmed that this is the issue by manually adding a 3 second setTimeout(). How do I make sure the drawPoll() function only executes after the choices.ForEach() iteration is complete?
2.) When calling the vote(choiceId) function and decrementing a choice the firebaseService observable does not pick up the correct value for "votes" because the observable kicks in before the vote deletion has finished executing. How do I re-arrange my code so that the observable waits until the vote document deletion is complete?
I tried to wrap the choices.forEach iteration in a promise but had difficulty getting this to work. And I wasn't sure where to even start to do a promise chain for the decrementChoice() and getChoices() since the getChoices() function doesn't always rely on the decrementChoice or incrementChoice() function when it's initilaized. It only relies on those when a vote is casted. Attached is my component and firebase service. Any help would be greatly appreciated!

** UPDATE **
I was able to solve issue #2 by creating a separate subcription just for vote updates. The code feels rather cumberson but at-least now #2 is no longer an issue. I'm still encountering the same issue though with #1 where the drawPoll() function is getting executed before this.poll.choices are done iterating and appending. I updated the question to reflect my updated code.

I want to override a function in companyService but have no idea how to do it.
Here is the code in company_service.js and I want to override the start function.
/** #odoo-module **/
import { browser } from "#web/core/browser/browser";
import { registry } from "#web/core/registry";
import { symmetricalDifference } from "#web/core/utils/arrays";

You can use the patch utility
However, there are situations for which it is not sufficient. In those cases, we may need to modify an object or a class in place. To achieve that, Odoo provides the utility function patch. It is mostly useful to override/update the behavior of some other component/piece of code that one does not control.
Example:
/** #odoo-module **/
import { patch } from "#web/core/utils/patch";
import { companyService } from "#web/webclient/company_service";
patch(companyService, 'module_name.companyService', {
start(env, { user, router, cookie }) {
return this._super(env, { user, router, cookie });
}
});
I'm trying to make a test using jest with Vue.
the details below.
Problem:
Can't mount using shallowMount option.
Situation:
Run the test after mounting the component using shallowMount option that provides in Vue-test-utils.
Throw error "Cannot read property 'XXXX' of undefined
This is my test code.
import myComponent from '#/~';
import Vuex from 'vuex';
import Vuelidate from 'vuelidate';
import { shallowMount, createLocalVue } from '#vue/test-utils';
const localVue = createLocalVue();
localVue.use(Vuex);
localVue.use(Vuelidate);
describe('myComponent~', () => {
let store;
beforeEach(() => {
store = new Vuex.Store({
modules: {
user: {
namespaced: true,
getters: {
profile: () => {
const profile = { name: 'blahblah' };
return profile;
},
},
},
},
});
});
describe('profile.name is "blahblah"', () => {
it('return something~', () => {
const wrapper = shallowMount(myComponent, {
localVue,
store,
mocks: {
$api: {
options: {
testMethod() {
return new Promise((resolve, reject) => {
resolve('test');
});
},
},
},
$i18n: {
t() {
return {
EN: 'EN',
KO: 'KO',
JP: 'JA',
SC: 'zh-CN',
TC: 'tw-CN',
};
},
},
},
});
expect(wrapper.find('.profile').text()).toBe('blahblah');
});
I think the problem is that property isn't set as a specified value or an empty value like an array or object.
But I don't know how I set properly the properties in my logic.
For example,
when the error yields "Cannot read property 'images' of undefined",
I add to a wrapper in the relevant method like this.
exampleMethod() {
this.something = this.something.map(item => {
if (item.detailContent.images) { // <-- the added wrapper is here
~~~logic~~~~
}
})
}
But the undefined properties are so many, I also think this way is not proper.
How I do solve this problem?
added
These are details about the above example method:
exampleMethod() {
this.something = this.something.map(item => {
let passValidation = false;
let failValidation = false;
if (item.detailContent.images) {
if (this.detail.showLanguages.includes(item.code)) {
if (this.configId !== 'OPTION1') {
item.detailContent.images = item.detailContent.images.map(element => {
return {
...element,
required: true,
}
});
}
checkValidationPass = true;
} else {
if (this.configId !== 'OPTION1') {
item.detailContent.images = item.detailContent.images.map(element => {
return {
...element,
required: false,
}
});
}
checkValidationPass = false;
}
return {
...item,
required: passValidation,
warning: failValidation,
}
}
});
if (this.configId === 'OPTION2') {
this.checkOption2Validation();
} else if (this.configId === 'OPTION3') {
this.checkOption3Validation();
} else {
this.checkOption1Validation();
}
},
And this is 'this.something':
data() {
return {
something: []
}
}
The detailContent is set here.
setMethod() {
this.something = [
...this.otherthings,
];
this.something = this.something.map(item => {
let details1 = {};
if (this.configId === 'OPTION2') {
details1 = {
images: [
{ deviceType: 'PC', titleList: [null, null], imageType: 'IMAGE' },
{ deviceType: 'MOBILE', titleList: [null, null, null] }

};
} else if (this.configId === 'OPTION3') {
details1 = {
images: [
{ deviceType: 'PC' },
{ deviceType: 'MOBILE' }
],
links: { linkType: 'EMPTY' },
};
}
let details2 = {
mainTitle: {
content: null,
}
}
let checkValidation = false;
this.detail.detailLanguages.forEach(element => {
if (element.language === item.code) {
details1 = { ...element };
if (!!element.mainTitle) {
details2 = { ...element };
} else {
details2 = {
...details2,
...element
};
}
if (this.configId !== 'OPTION1') {
details1.images = details1.images.map(image => {
return {
...image,
required: true,
}
});
}
checkValidation = true;
}
});
return {
...item,
detailContent: this.configId !== 'OPTION1' ? details1 : details2,
required: false,
warning: false,
}
});
},
I'm trying to 'stub' a method via testdoubleJS to do a unit test for this method (doing npm test). It is the first time I'm doing this, so it is still hard to understand for me.
For my attempt - shown below - I do get the error TypeError: mediaAddImagePoint.run is not a function
This is how my method I want to test looks like:
import { ValidatedMethod } from 'meteor/mdg:validated-method'
import { LoggedInMixin } from 'meteor/tunifight:loggedin-mixin'
import { Media } from '/imports/api/media/collection.js'
const mediaAddImagePoint = new ValidatedMethod({
name: 'media.point.add',
mixins: [LoggedInMixin],
checkLoggedInError: { error: 'notLogged' },
validate: null,
run ({ id, x, y }) {
Media.update(
{ _id: id },
{
$push: {
'meta.points': {
id: Random.id(),
x,
y
}
}
}
)
}
})
And this is how I'm trying to test this method via testdouble:
import { expect } from 'chai'
import td from 'testdouble'
describe('media.point.add', function () {
describe('mediaAddImagePoint', function () {
let Media = td.object(['update'])
let ValidatedMethod = td.function()
let LoggedInMixin = td.function()
let mediaAddImagePoint
beforeEach(function () {
td.replace('meteor/mdg:validated-method', { ValidatedMethod })
td.replace('meteor/tunifight:loggedin-mixin', { LoggedInMixin })
td.replace('/imports/api/media/collection.js', { Media })
mediaAddImagePoint = require('../../imports/api/media/methods/imagePoints.js').mediaAddImagePoint
})
afterEach(function () {
td.reset()
})
it('should add image point', function () {
const query = { id: 'sampleID', x: 12, y: 34 }
mediaAddImagePoint.run(query)
td.verify(Media.update(query))
})
})
})
I'm trying to write a unit test for an init function and I'm getting an error where I am calling collectionReport.init() in the test....
TypeError: undefined is not an object
This is the code I am trying to test...
class CollectionsReport {
constructor({ editCollectionsId, hasCollections}) {
this.editCollectionsId = editCollectionsId;
this.hasCollections = hasCollections
}
init({ id, name }) {
this.id = id;
this.name = name;
// need to test this
if (this.hasCollections) {
this.collection = this.collections.find(c => c.staticId === 'CAR-COLLECTION');
}
}
And this is my test so far
describe('CollectionsReport', () => {
const collectionArgs = {
editCollectionsId: jasmine.createSpy(),
hasCollections: false,
};
const collections = [
{
id: 1,
name: 'foo',
staticId: 'CAR-COLLECTIONS',
},
{
id: 2,
name: 'bar',
staticId: 'TRUCK-COLLECTIONS',
},
];
let collectionReport;
beforeEach(() => {
collectionReport = new CollectionsReport(collectionArgs);
});
describe('.init()', () => {
it('should test hasCollections', () => {
collectionReport.init();
//test this.hasCollections here
});
});
});
I'm sure its a mess, so please comment on how to fix and improve it.
Not sure what is the purpose of the CollectionsReport class, but maybe this will lead you to the right direction:
class CollectionsReport {
constructor({ editCollectionsId, hasCollections}) {
this.editCollectionsId = editCollectionsId
this.hasCollections = hasCollections
}
init({ collections, staticId }) {
this.hasCollections = !!collections.find(c => c.staticId === staticId)
}
}
describe('CollectionsReport', () => {
const collectionArgs = {
editCollectionsId: jasmine.createSpy(), // Not really using it
hasCollections: false
}
const collections = [
{
id: 1,
name: 'foo',
staticId: 'CAR-COLLECTIONS'
}, {
id: 2,
name: 'bar',
staticId: 'TRUCK-COLLECTIONS'
}
]
describe('.init()', () => {
let collectionReport
beforeEach(() => {
collectionReport = new CollectionsReport(collectionArgs)
})
it('should test hasCollections', () => {
collectionReport.init({ collections, staticId: 'CAR-COLLECTIONS' })

I am trying to set up a mutation with modified code from the Relay Todo example.
When I try to compile I get the following error:

I have duplicated the Todo code so I don't know why the Todo mutation is working correctly but my new Campaign test isn't.
This is my database.js file, I have removed the Todo related items to make the document easier to read:
export class Campaign {}
export class User {}
// Mock authenticated ID
const VIEWER_ID = 'me';
// Mock user data
const viewer = new User();
viewer.id = VIEWER_ID;
const usersById = {
[VIEWER_ID]: viewer,
};
// Mock campaign data
const campaignsById = {};
const campaignIdsByUser = {
[VIEWER_ID]: [],
};
let nextCampaignId = 0;
addCampaign('Campaign1');
addCampaign('Campaign2');
addCampaign('Campaign3');
addCampaign('Campaign4');
export function addCampaign(text) {
const campaign = new Campaign();
//campaign.complete = !!complete;
campaign.id = `${nextCampaignId++}`;
campaign.text = text;
campaignsById[campaign.id] = campaign;
campaignIdsByUser[VIEWER_ID].push(campaign.id);
return campaign.id;
}
export function getCampaign(id) {
return campaignsById[id];
}
export function getCampaigns(status = 'any') {
const campaigns = campaignIdsByUser[VIEWER_ID].map(id => campaignsById[id]);
if (status === 'any') {
return campaigns;
}
return campaigns.filter(campaign => campaign.complete === (status === 'completed'));
}
This is my schema.js file, again I have removed the Todo related items to make the document easier to read:

const GraphQLUser = new GraphQLObjectType({

This is my AddCampaignMutation.js file:
import Relay from 'react-relay';
export default class AddCampaignMutation extends Relay.Mutation {
static fragments = {
viewer: () => Relay.QL`
fragment on User {
id,
totalCount,
}
`,
};
getMutation() {
console.log('getMutation');
return Relay.QL`mutation{addCampaign}`;
}
getFatQuery() {
console.log('getFatQuery');
return Relay.QL`
fragment on AddCampaignPayload #relay(pattern: true) {
campaignEdge,
viewer {
campaigns,
},
}
`;
}
getConfigs() {
console.log('getConfigs');
return [{
type: 'RANGE_ADD',
parentName: 'viewer',
parentID: this.props.viewer.id,
connectionName: 'campaigns',
edgeName: 'campaignEdge',
rangeBehaviors: ({orderby}) => {
if (orderby === 'newest') {
return 'prepend';
} else {
return 'append';
}
},
//rangeBehaviors: ({status}) => {
// if (status === 'completed') {
// return 'ignore';
// } else {
// return 'append';
// }
//},
}];
}
getVariables() {
console.log('getVariables');
return {
text: this.props.text,
};
}
getOptimisticResponse() {
console.log('getOptimisticResponse');
return {
// FIXME: totalCount gets updated optimistically, but this edge does not
// get added until the server responds
campaignEdge: {
node: {
text: this.props.text,
},
},
viewer: {
id: this.props.viewer.id,
totalCount: this.props.viewer.totalCount + 1,
},
};
}
}
And finally this is the app file that contains my text input and the call to AddCampaignMutation:
import AddTodoMutation from '../mutations/AddTodoMutation';
import AddCampaignMutation from '../mutations/AddCampaignMutation';
import TodoListFooter from './TodoListFooter';
import TodoTextInput from './TodoTextInput';
import React from 'react';
import Relay from 'react-relay';
class TodoApp extends React.Component {
_handleTextInputSave = (text) => {
debugger;
this.props.relay.commitUpdate(
new AddTodoMutation({text, viewer: this.props.viewer})
);
};
_campaignHandleTextInputSave = (text) => {
debugger;
this.props.relay.commitUpdate(
new AddCampaignMutation({text, viewer: this.props.viewer})
);
};
render() {
const hasTodos = this.props.viewer.totalCount > 0;
return (
<div>
<section className="todoapp">
<header className="header">
<TodoTextInput
autoFocus={true}
className="new-campaign"
onSave={this._campaignHandleTextInputSave}
placeholder="Campaign name"
/>
<h1>
todos
</h1>
<TodoTextInput
autoFocus={true}
className="new-todo"
onSave={this._handleTextInputSave}
placeholder="What needs to be done?"
/>
</header>
{this.props.children}
{hasTodos &&
<TodoListFooter
todos={this.props.viewer.todos}
viewer={this.props.viewer}
/>
}
</section>
</div>
);
}
}
export default Relay.createContainer(TodoApp, {
fragments: {
viewer: () => Relay.QL`
fragment on User {
totalCount,
${AddTodoMutation.getFragment('viewer')},
${AddCampaignMutation.getFragment('viewer')},
${TodoListFooter.getFragment('viewer')},
}
`,
},
});
Well I feel a bit silly but I found out what the problem was. I didn't realise that my schema.json file was not updating!
If anyone has a similar problem make sure that the schema.json file is up to date by running the following command to rebuild it:
npm run-script update-schema
