QUESTION

How to use TypeScript to make sure two objects have a same structure (without interface)?

Asked 2022-Apr-15 at 15:19

I'm currently working on a web project which heavily utilizes internationalization (i18n) and I have a hard time figuring out how to make sure all languages share exact same keys.

Here's a simple example of src/lang/en.ts file:

1export default {
2  title: "My Website Project",
3  description: "This is an example of a file which contains phrases and their keys",
4  hello: "Hello!",
5};
6

and here's a simple example of src/lang/id.ts file:

1export default {
2  title: "My Website Project",
3  description: "This is an example of a file which contains phrases and their keys",
4  hello: "Hello!",
5};
6export default {
7  title: "Proyek Website Saya",
8  description: "Ini adalah contoh dari sebuah file yang mengandung beberapa frasa beserta kata kuncinya",
9  hello: "Halo!",
10};
11

Now, I want TypeScript to make sure those files have same keys (not more, not less). So if I put cat property into src/lang/id.ts, then:

1export default {
2  title: "My Website Project",
3  description: "This is an example of a file which contains phrases and their keys",
4  hello: "Hello!",
5};
6export default {
7  title: "Proyek Website Saya",
8  description: "Ini adalah contoh dari sebuah file yang mengandung beberapa frasa beserta kata kuncinya",
9  hello: "Halo!",
10};
11export default {
12  title: "Proyek Website Saya",
13  description: "Ini adalah contoh dari sebuah file yang mengandung beberapa frasa beserta kata kuncinya",
14  hello: "Halo!",
15  cat: "Kucing", // <-- this must be error because "cat" doesn't exist in en.ts file!
16};
17

But I can't build an interface like this

1export default {
2  title: "My Website Project",
3  description: "This is an example of a file which contains phrases and their keys",
4  hello: "Hello!",
5};
6export default {
7  title: "Proyek Website Saya",
8  description: "Ini adalah contoh dari sebuah file yang mengandung beberapa frasa beserta kata kuncinya",
9  hello: "Halo!",
10};
11export default {
12  title: "Proyek Website Saya",
13  description: "Ini adalah contoh dari sebuah file yang mengandung beberapa frasa beserta kata kuncinya",
14  hello: "Halo!",
15  cat: "Kucing", // <-- this must be error because "cat" doesn't exist in en.ts file!
16};
17export default interface LanguageStruct {
18  title: string,
19  description: string,
20  hello: string,
21};
22

Because there's hundreds of phrases for each language in the real project and writing those keys one-by-one would be both time consuming and exhausting. I wonder if there's a trick to do with TypeScript for that problem, or at least there's some kind of automation to do that job.

ANSWER

Answered 2022-Apr-15 at 15:19

Use keyof typeof someObject to construct a type from the keys of an object (e.g. the first language strings). Then restrict your other object (the other languages) to have that type as key, and string as value using Record. So the type you're looking for is Record<keyof typeof someObject, string>. Example:

1export default {
2  title: &quot;My Website Project&quot;,
3  description: &quot;This is an example of a file which contains phrases and their keys&quot;,
4  hello: &quot;Hello!&quot;,
5};
6export default {
7  title: &quot;Proyek Website Saya&quot;,
8  description: &quot;Ini adalah contoh dari sebuah file yang mengandung beberapa frasa beserta kata kuncinya&quot;,
9  hello: &quot;Halo!&quot;,
10};
11export default {
12  title: &quot;Proyek Website Saya&quot;,
13  description: &quot;Ini adalah contoh dari sebuah file yang mengandung beberapa frasa beserta kata kuncinya&quot;,
14  hello: &quot;Halo!&quot;,
15  cat: &quot;Kucing&quot;, // &lt;-- this must be error because &quot;cat&quot; doesn't exist in en.ts file!
16};
17export default interface LanguageStruct {
18  title: string,
19  description: string,
20  hello: string,
21};
22const en = {
23  title: &quot;My Website Project&quot;,
24  description: &quot;This is an example of a file which contains phrases and their keys&quot;,
25  hello: &quot;Hello!&quot;,
26};
27
28const de: Record&lt;keyof typeof en, string&gt; = {
29  title: &quot;Proyek Website Saya&quot;,
30  description: &quot;Ini adalah contoh dari sebuah file yang mengandung beberapa frasa beserta kata kuncinya&quot;,
31  hello: &quot;Halo!&quot;,
32  cat: &quot;Kucing&quot;, // this is highlighted as an error
33};
34

You are using a @dataclass way of defining your model. I'm not aware that will work ... It should be:

1from django.shortcuts import render
2from django.http import HttpResponse
3from .models import Feature
4
5# Create your views here.
6def index(request):
7    features = Feature.objects.all()
8    return render(request, 'index.html', {'features' : features})
9from django.db import models
10
11# Create your models here.
12class Feature(models.Model):
13    name: models.CharField(max_length=100)

Also, have you run migrations? (I suspect not or I think you'd have seen an error here). You should run python manage.py makemigrations followed by python manage.py migrate when you create or amend a model definition - this is what creates/changes it in the DB, and without that there's not a lot to display in admin anyway ...

It's possible if you ran migrate it created an "empty" model maybe, since you were missing the = - I really don't know exactly what this code would do without testing it.

QUESTION

MQL4 WebRequest POST Json to Django API using Django rest framework, getting \x00 at the end of body

Asked 2022-Feb-17 at 08:16

I am using Django only for few weeks so there might be some mistakes.

I have an API using Django rest framework, which seems to work well. Using postman every thing is ok

I send data using WebRequest in Mql4 to the api

1string data = &quot;{ ... }“; 
2char post_data[];
3post_data = StringToCharArray(data, post_data, WHOLE_ARRAY);
4int r = WebRequest(&quot;POST&quot;, &quot;http://127.0.0.1/api/symbol/&quot;,&quot;Content-Type: application/json&quot;,5000, data,res_data, res_headers);
5

The data given to WebRequest is fine but the function add \x00 at the end of body.

Here is my post data when it arrive to Django rest framework

1string data = &quot;{ ... }“; 
2char post_data[];
3post_data = StringToCharArray(data, post_data, WHOLE_ARRAY);
4int r = WebRequest(&quot;POST&quot;, &quot;http://127.0.0.1/api/symbol/&quot;,&quot;Content-Type: application/json&quot;,5000, data,res_data, res_headers);

if a send the same data removing the \x00 with Postman every thing goes well.

Is there a misconfiguration client side with mql4 ?

Or can I remove the received data to remove this \x00 ?

I find my solution, when I converted my data string to post_Data object the length was not WHOLE_ARRAY, but StringLen.

QUESTION

Why my translations in django i18n don't work

Asked 2022-Feb-16 at 01:15

I've been following 3 different tutorials for text translation in django, and with none of them my translation has worked, however I was doing exactly the same steps as in the tutorials. Django just doesn't translate my text, it goes without any kind of error. My last try was with this course: https://www.youtube.com/watch?v=AlJ8cGbk8ps. But just to be sure I'm adding my code below

I think I should also mention that I use virtual environment, but when I switched it off it doesn't work either. Whether I switch LANGUAGE_CODE to es or pl it takes no effect. I've compiled them too.

QUESTION

How to insert a &lt;a&gt; tag or icon inside Vuetify internationalization?

Asked 2022-Feb-14 at 19:20

I'm currently working on a project based on Vuetify. I need to insert a <a> tag and icon inside an internationalization text. Generally, it is easy to insert a variable as below shows,

this.$vuetify.lang.$t('I'm {0}', varirable_name)

but in this way, I cannot insert <a> tag or an icon <v-icon>, how could I achieve it? Just like this,

1`this.$vuetify.lang.$t('Here is an icon {0} and a {1}', &lt;v-icon /&gt;, &lt;a&gt;link&lt;/a&gt;)`

ANSWER

Answered 2022-Feb-14 at 19:20

You can use v-html directive to output raw HTML. It will work for basic tags but won't work for Vuetify's v-tags (for example, v-icon).

1`this.$vuetify.lang.$t('Here is an icon {0} and a {1}', &lt;v-icon /&gt;, &lt;a&gt;link&lt;/a&gt;)`
2new Vue({
3  vuetify: new Vuetify(),
4  data() {
5    return {
6      message: this.$vuetify.lang.t('Here is an bold {0} and a {1}', "&lt;strong&gt;text&lt;/strong&gt;", "&lt;a&gt;link&lt;/a&gt;")
7    }
8  }
9
10}).$mount('#app')
1`this.$vuetify.lang.$t('Here is an icon {0} and a {1}', &lt;v-icon /&gt;, &lt;a&gt;link&lt;/a&gt;)`
2new Vue({
3  vuetify: new Vuetify(),
4  data() {
5    return {
6      message: this.$vuetify.lang.t('Here is an bold {0} and a {1}', "&lt;strong&gt;text&lt;/strong&gt;", "&lt;a&gt;link&lt;/a&gt;")
7    }
8  }
9
10}).$mount('#app')&lt;link href="https://fonts.googleapis.com/css?family=Roboto:100,300,400,500,700,900" rel="stylesheet"&gt;
11&lt;link href="https://cdn.jsdelivr.net/npm/@mdi/font@6.x/css/materialdesignicons.min.css" rel="stylesheet"&gt;
12&lt;link href="https://cdn.jsdelivr.net/npm/vuetify@2.x/dist/vuetify.min.css" rel="stylesheet"&gt;
13
14
15&lt;div id="app"&gt;
16  &lt;v-app&gt;
17    &lt;v-main&gt;
18      &lt;v-container&gt;&lt;span v-html="message"&gt;&lt;/span &gt;&lt;/v-container&gt;
19      &lt;/v-main&gt;
20    &lt;/v-app&gt;
21  &lt;/div&gt;
22
23  &lt;script src="https://cdn.jsdelivr.net/npm/vue@2.x/dist/vue.js"&gt;&lt;/script&gt;
24  &lt;script src="https://cdn.jsdelivr.net/npm/vuetify@2.x/dist/vuetify.js"&gt;&lt;/script&gt;

I wouldn't recommend using Vuetify tags in composite format strings. Instead, translate the text inside of the tag.

1`this.$vuetify.lang.$t('Here is an icon {0} and a {1}', &lt;v-icon /&gt;, &lt;a&gt;link&lt;/a&gt;)`
2new Vue({
3  vuetify: new Vuetify(),

5    return {
6      message: this.$vuetify.lang.t('Here is an bold {0} and a {1}', "&lt;strong&gt;text&lt;/strong&gt;", "&lt;a&gt;link&lt;/a&gt;")

QUESTION

Show Two Languages at once

Asked 2022-Feb-07 at 10:23

Fisrt of all i am following this guide for localization which is the official guideline of flutter but at

1AppLocalizations.of(context)!.helloWorld
2

It gives error as null

I think this is maybe because I recently updated flutter to 2.10 please confirm if that is the case

I want to achieve this kind of results like English on right and Urdu Language of Left which i don't know how to do that because in samples and guides they just show how to change overall app language not just for some strings

enter image description here

Also for time being, I have used easy_localization: 3.0.0 but still the problem is how i support multiple language at once with this package

ANSWER

Answered 2022-Feb-07 at 10:23
  1. Don't use localization for this part - drawer widget - text items
  2. wrap drawer widget with Directionality widget to prevent it from mirroring and make text in the same place.
  3. pop the drawer after using switch widget.

Example:

1AppLocalizations.of(context)!.helloWorld
2import 'package:flutter/material.dart' as ltr;
3
4
5drawer: Directionality(
6    textDirection: ltr.TextDirection.ltr,

8      color: Colors.lightGreen,
9      child: Column(

ERRORS: inside.UserProfile.user: (fields.E301) Field defines a relation with the model 'auth.User', which has been swapped out

Asked 2022-Jan-28 at 18:37

I am a beginner in Django. I am trying to build an app with user authentication. However I want extra fields like country and phone number, and I don't want any username field (I want the phone number to act as the username), so I built a custom user class. There are questions that have already been asked that have the same error, but they are not exactly relevant to my use case and the solutions don't work for me.

You are defining a relationship to the default User Model, which you are not using anymore as you have created a custom user model. Remove the one_to_one_field to avoid this error And to further errors you have to create a custom manager

Note: As you are using uid as your username field, you have to write a custom authentication backend so that you can use the phone number to authenticate the user, otherwise you have to use the phone number as a username field if you don't want to create a custom authentication backend.

QUESTION

is runtime language translation possible with angular (@angular/localize)?

Asked 2022-Jan-26 at 03:20

I am trying to learn and add angular internationalization in a project. I can understand only compile time translation from angular documents (https://angular.io/guide/i18n-overview).

I need some thing like this https://stackblitz.com/github/ngx-translate/example which is third party library 'ngx-translate'.

Can't we achieve the same runtime translation just with angular library without any third party library ?

Please guide me if runtime translation is possible with angular library.

ANSWER

Answered 2022-Jan-26 at 03:20

no solutions for runtime with i18n from angular box. Only use ngx-translate. Angular team still only talks about "we will do it in next version", but no success. I work under big project and we use ngx-translate from angular version 4 or 6. u can trust this fird party library. i18n can only build app for some baseHref like:

https://your.domain/en/...

https://your.domain/de/...

When u need to compile a lot of app for work with i18n. ngx-translate - only 1 app, and translations can be splitted by modules where this translations is need.

My advice - use ngx-translate and when angular team will make runtime language reload - rewrite project part for translation

QUESTION

How to generate dynamic paths for non-default locales in Next.js?

Asked 2022-Jan-22 at 16:29

I am building a Next.js app with internationalization using next-i18next. Pages are generated for all the pages of my site for both English and French, except for pages with dynamic routes: (i.e., blog/[id]/[blog-title]). For pages with dynamic routes, pages are generated for English, but not for French.

I should note that the blog entries are the same in both languages. So if the user click on a blog entry in the list, they will get the same blog entry.

When a French language user goes to a page with a dynamic route they get a 404. I am new to React and Next so I could be doing something dumb here.

1// next-i18next.config.js
2module.exports = {
3  i18n: {
4    locales: ['en', 'fr'],
5    defaultLocale: 'en',

ANSWER

Answered 2022-Jan-07 at 20:56

For dynamic routes, you have to explicitly return the locales you want to be pre-generated from the getStaticPaths function. If you don't, Next.js will only generate pages for the default locale.

From Internationalized Routing documentation:

For pages using getStaticProps with Dynamic Routes, all locale variants of the page desired to be prerendered need to be returned from getStaticPaths. Along with the params object returned for paths, you can also return a locale field specifying which locale you want to render.

This can be achieved by modifying your getStaticPaths function to generate a path for each slug/locale combination.

1// next-i18next.config.js
2module.exports = {
3  i18n: {
4    locales: ['en', 'fr'],

QUESTION

Is my django post method even being called?

Asked 2022-Jan-22 at 04:07

I am trying to make a trading log app in Django but I have run into a few snags. It feels like my post method might night be being called when the submit button is clicked. I have tried printing and logging and neither ever fire in the post() method. The logging works fine in the get() method. Additionally I keep being routed back to my base index page even though I am rendering trading_log/add-order.html. I have also tried using a HTTPResponseRedirect. Both to no avail. I am really not sure what I am doing wrong at this point.
