How do I contribute new files to the KhanAcademy Github? - khan-academy

How do I commit new files to the khan-api repository? I created a simple MVC PHP example client (As the current php test client was quite confusing).
e.g. This is how it looks now:
if (isset($_GET['login']) && $_GET['login']) {
$this->login();
}
elseif (isset($_GET['oauth_token']) && $_GET['oauth_token']) {
$this->doOathAuthentication();
}
elseif (isset($_GET['logged_in']) && $_GET['logged_in']) {
$this->mainPage();
}
else {
$this->defaultPage();
}
Which makes it a bit easier to understand :-)

We're happy to accept pull requests on Github! We don't use PHP much so I'm not sure how quickly we'll be able to review it, but if you make sure to mention exactly what you're improving over the existing client, that will help us evaluate the pull request.

Why is my dynamic Gatsby page not working

I'm trying to create dynamic pages based on a database that grows by the minute. Therefor it isn't an option to use createPage and build several times a day.
I'm using onCreatePage here to create pages which works fine for my first route, but when I try to make an English route somehow it doesn't work.
gatby-node.js:
exports.onCreatePage = async ({ page, actions: { createPage } }) => {
if (page.path.match(/^\/listing/)) {
page.matchPath = '/listing/:id'
createPage(page)
}
if (page.path.match(/^\/en\/listing/)) {
page.matchPath = '/en/listing/:id'
createPage(page)
}
}
What I'm trying to achieve here is getting 2 dynamic routes like:
localhost:8000/listing/123 (this one works)
localhost:8000/en/listing/123 (this one doesn't work)
My pages folder looks like this:
pages
---listing.tsx
---en/
------listing.tsx
Can anyone see what I'm doing wrong here?
--
P.S. I want to use SSR (available since Gatsby v4) by using the getServerData() in the templates for these pages. Will that work together with pages created dynamically with onCreatePage or is there a better approach?
According to what we've discussed in the comment section: the fact that the /en/ path is never created, hence is not entering the following condition:
if (page.path.match(/^\/en\/listing/)) {
page.matchPath = '/en/listing/:id'
createPage(page)
}
Points me to think that the issue is on your createPages API rather than onCreatePage, which means that your english page is not even created.
Keep in mind that onCreatePage API is a callback called when a page is created, so it's triggered after createPages.
If you add a console.log(page.path) you shouldn't see the English page in the IDE/text editor console so try debugging how are you creating the /en/ route because it seems that onCreatePage doesn't have any problem.

How to create a static website generator in React

Tech stack - Node.js, MongoDB for the database, Strapi CMS for editing and API, React - my application.
I have a database with a long list of entries and a ready-to-use application that allows users to read data from the database. I need to be able to generate a simple website with a single entity from my database as a source to fill the template.
Mockup
Here is a mock-up. Hopefully, it will make things a bit clearer.
Clarification
After a day of thinking about the task, I believe I need something like a simplest static website generator - an application that will allow me to select a single bit of data from the list and generate a small website filled with it. The end goal is to get a website in some subfolder of my application where I can get it and use it however I need.
A bit more about specifics:
It will be used locally
Security can be neglected
Running always in development is not a problem (just in case, thinking about additional question #2)
Few additional questions:
Is it possible to run NPM scripts from the application (like npm build)
Is there any way to show one component in development mode, but replace it with another during building for production?
App.js
//...
function App() {
if() {
return <AdminUI /> // This one is to be shown in development mode
} else {
return <Website /> // This one is to be used instead of AdminUI in the build
}
UPDATE
Well, I'm digging a path to create a site generator and so far I come up with the following basic plan:
Get my template ready
Create a new directory for my website
Copy a template to the new folder
Get an HTML file, parse it to a string to modify
Swap some bits with my data
Save to a file from the modified string
repeat if needed for other files.
If that works as expected, the whole process probably might be improved by moving from a fixed template to a component, that will be prepared with a JavaScript bundler and started with the help of something like node-cmd (to run shell commands from my application)...
What you want could be achievable, but if it's just a string and little else, I'd say it's much simpler to fetch the data at startup from a given file, and populate from there. You can put a JSON file under the public folder (together with other static data, like images) and have the file being your configuration.
In the App.js file, write an async componentDidMount() and you can do an await axios.get("") with your configuration.
So App.js would look like (code written on the fly, didn't check in an IDE):
export class App extends React.App {
constructor(props) {
super(props);
this.state = { loading: true, };
}
async componentDidMount() {
const response = await axios.get("your/data.json");
this.setState({ loading: false, ... whatever})
}
render = () => (
<>
(this.state.loading && <div>Still loading...</div>)
(this.state.adminData && <AdminUI data={this.state.admingData} />)
(this.state.devData && <Website data={this.state.devData} />)
</>
)
}
If you don't care about security, wouldn't be much simpler like this? And if you use TypeScript you'll have a much much simpler life in handling the data too.
Maybe it's worth doing an AdminUI to generate the JSON, and the another UI which reads the JSON, so you end up doing two UIs. The template-generated UI could even ask for a JSON file to bootstrap directly to the user, if it simplifies... In general, an approach based on simple JSON sounds a lost simpler than going for a CI/CD pipeline.

Windows.UI.Popups.MessageDialog does not work for Windows 10 IoT

await new Windows.UI.Popups.MessageDialog("Test").ShowAsync();
Has anyone else noticed this? Is there an easy work around ?
I have the some problem and I did't found any trick. I made myself a MessageDialog with a and It's not so hard to build it. Try do take a look this http://bitaware.altervista.org/messagedialog-for-iot/
The unique problem is that it do not work across platforms. If you would this behavior you have to get a condition
string platform = AnalyticsInfo.VersionInfo.DeviceFamily;
if (platform == "Windows.IoT")
{
//Your code for IoT
}
else
{
//Your code for other devices
}
I know is not elegant but I think we have no other choice.
I hope it was helpful

symfony2 get firewall name on login page

I'd want to use a login page to access different firewalls, so I need to get information about the firewall I'm logging in.
In my controller I'd use
$this->container->get('security.context')->getToken()->getProviderKey()
but as an anonymous user I don't have access to getProviderKey method.
I could also parse
_security.xxx.target_path
to get xxx firewall but I'm looking for a more general solution if it exists at all.
Any idea?
As of symfony 3.2, you can now get the current firewall configuration using the following:
public function indexAction(Request $request)
{
$firewall = $this->container
->get('security.firewall.map')
->getFirewallConfig($request)
->getName();
}
Ref: http://symfony.com/blog/new-in-symfony-3-2-firewall-config-class-and-profiler
For Symfony 3.4 I wrote this to avoid referencing the non-public "security.firewall.map" service:
$firewallName = null;
if (($firewallContext = trim($request->attributes->get("_firewall_context", null))) && (false !== ($firewallContextNameSplit = strrpos($firewallContext, ".")))) {
$firewallName = substr($firewallContext, $firewallContextNameSplit + 1);
}
(Referencing "security.firewall.map" on 3.4 will throw an exception.)
Edit: This will not work in a custom exception controller function.
I was doing a little research on this myself recently so that I could send this information in an XACML request as part of the environment.
As far as I can tell from GitHub issues like this one:
https://github.com/symfony/symfony/issues/14435
There is currently no way to reliably get the information out of Symfony except the dirty compiler pass hack suggested on the linked issue. It does appear from the conversation on these issues, they are working on making this available, however, the status is still open, so we will have to be patient and wait for it to be provided.
#Adambean's answer is pretty elegant, but I'd write it as a one-liner:
$firewallName = array_slice(explode('.', trim($request->attributes->get('_firewall_context'))), -1)[0];
The difference is that $firewallName will always be a string (which may be empty).
Also, please note that this answer (like #Adambean's) doesn't work for a firewall with a dot in its name.

Drupal - Security check all site paths by role

I'm writing this in the forlorn hope that someone has already done something similar. I would have posted on drupal.org - but that site is about as user-friendly as a kick in the tomatoes.
I don't know about you, but when I develop I leave all my Drupal paths with open access, and then think about locking them down with access permissions at the end.
What would be be really useful is a module which parses all the paths available (by basically deconstructing the contents of the menu_router table) and then trying them (curl?) in turn whilst logged-in as a given user with a given set of roles.
The output would be a simple html page saying which paths are accessible and which are not.
I'm almost resigned to doing this myself, but if anyone knows of anything vaguely similar I'd be more than grateful to hear about it.
Cheers
UPDATE
Following a great idea from Yorirou, I knocked together a simple module to provide the output I was looking for.
You can get the code here: http://github.com/hymanroth/Path-Lockdown
My first attempt would be a function like this:
function check_paths($uid) {
global $user;
$origuser = $user;
$user = user_load($uid);
$paths = array();
foreach(array_keys(module_invoke_all('menu')) as $path) {
$result = menu_execute_active_handler($path);
if($result != MENU_ACCESS_DENIED && $result != MENU_NOT_FOUND) {
$paths[$path] = TRUE;
}
else {
$paths[$path] = FALSE;
}
}
$user = $origuser;
return $paths;
}
This is good for a first time, but it can't handle wildcard paths (% in the menu path). Loading all possible values can be an option, but it doesn't work in all cases. For instance, if you have %node for example, then you can use node_load, but if you have just %, then you have no idea what to load. Also, it is a common practice to omit the last argument, which is a variable, in order to correctly handle if no argument is given (eg. display all elements).
Also, it might be a good idea to integrate this solution with the Drupal's testing system.
I did a bit of research and wasn't able to find anything. Though I'm inclined to think there is a way to check path access through Drupal API as opposed to CURL - but please keep me updated on your progress / let me know if you would like help developing. This would a great addition to the Drupal modules.
