I want to add "Weather: 24C" to the rental-listing component of the super-rentals tutorial app.
Where would be the "best-practices" place to put this ajax request?
Ember.$.getJSON(`http://api.openweathermap.org/data/2.5/weather?q=${location}&APPID=${apiKey}`)
.then(function(json) {
return JSON.parse(json).main.temp;
});
Do I need to add a component, add a model, add a service, add a second adapter, modify the existing adapter? Something else? All of these? Is the problem that the tutorial uses Mirage? I ask this because when I think I'm getting close, I get an error like this:
Mirage: Your Ember app tried to GET
'http://api.openweathermap.org/data/2.5/weather?q=london&APPID=5432',
but there was no route defined to handle this request.
Define a route that matches this path in your
mirage/config.js file. Did you forget to add your namespace?
You need to configure mirage to allow you making calls to outside in case mirage is active; what I mean is using this.passthrough function within mirage/config.js, that is explained in api documentation quite well.
Regarding your question about where to make the remote call is; it depends:
If you need the data from the server to arrive in case a route is about to open; you should prefer putting it within model hook of the corresponding route.
If you intend to develop a component that is to be reused from within different routes or even from within different applications with the same remote call over and over again; you can consider putting the ajax remote call to a component. Even if that is not a very common case usually; it might be the case that a component itself should be wrapped up to fetch the data and display it by itself for reusing in different places; there is nothing that prevents you to do so. However by usually applying data-down action-up principle; generally the remote calls fall into routes or controllers.
Whether using an ember-data model is another thing to consider. If you intend to use ember-data; you should not directly use Ember.$.ajax but rather be using store provided by ember-data and perhaps providing your custom adapter/serializer to convert data to the format ember-data accepts in case the server do not match to the formats that ember-data accepts. In summary; you do not need to use models if you use pure ajax as you do in this question.

I'm new to Laravel and I am handed an existing application that is composed of two parts:
1 - An admin backend built on Laravel and uses Vueify
2 - The frontend website built on next.js and uses react components
The admin part communicates with Laravel using the "web routes" but also uses the "api routes" as well since the vue components make AJAX requests using those "api routes".
I am now tasked with "connecting" the frontend part to the laravel app. The frontend part will be using AJAX as well to communicate with laravel but I was told I should not use the same "api route" that is used by the admin backend because that has a lot more privileges that should not be accessible by the frontend. Basically it's a security risk and that I should somehow separate the two.
I'm not actually sure which term to use.. I initially thought it was called "channel" but I see that channel is one of the 4 "ways" of connecting to laravel (the other 3 being web, api and console). So I think routes is the term to use and forgive me for the double-quotes.
I have made a simple diagram to show the structure I mean. What I need to know is is there a way to create a second api route that would be used exclusively by the frontend and would include only a limited set of priviledges. I imagine something like /frontapi/ or /webapi/ as opposed to /api/ which is used now by the backend.
Thanks a lot for your help and please correct me if I am using wrong terminology.
EDIT
Thank you all for answering the part regarding separating the route prefix and the api route files.
One part of the question that I realized late that I hadn't made clear was the importance of separating the API Keys for both APIs since I think that is the main security issue and what would really make then two individual API "Channels or ways". I think that is one reason why I was confusing about the terminology because "way" sounded to me more separate that just a "route". I've also edited the question to reflect that. Thank you again for taking the time to help.
You can decompose routes in as many files as you want, you can also give each file its own prefix (like how api.php routes start with /api)
The modification need to be done in App\Providers\RouteServiceProvider
//in map() add $this->mapApiTwoRoutes()
public function map()
{
$this->mapApiRoutes();
$this->mapApiTwoRoutes();//<---this one
$this->mapWebRoutes();
}
//now add the method mapApiTwoRoutes
protected function mapApiTwoRoutes()
{
Route::prefix('api2')//<-- prefix in the url
->middleware('api')//<-- api middleware (throttle and such check App\Http\Kernal.php)
->namespace('App\Http\Controllers') //<-- you can modify the namespace of the controllers
->group(base_path('routes/apiTwo.php'));//<-- file containing the routes
}
And that's it.
You need to define a new route file, firstly add a new entry $this->mapApi2Routes(); in the map() function in app\Providers\RouteServiceProvider.
Then add a new function in that file, basically copying the mapApiRoutes() function, call it mapApi2Routes(). You can use different middleware etc. for the new file.
The last step would be adding a new file api2.php in the routes folder.
I'm trying to use express-flash in a standard web express js app. I don't want to use session, because I want to do the app as stateless as possible, but when I try to use without session, the app show me this error:
req.flash() requires sessions
Can I use express-flash without session? Can I use other alternatives for this kind of messages?
Thanks.
Note: A flash message is a variable stored within a session that is only available once, for the next request. That is if we put a flash variable and renders a page, the flash variable is available but if we render the same (or other) page again the flash variable is not present (it is destroyed).
-- acanimal
Based on this premise, you need to have sessions to use message flashing.
One way I think you can accomplish what you want is to add an item to the request (req) object in your middleware, and then in your controller, check if the key exists. You can then pass a specific message to your template, assuming you're using a template engine or pass it as part of your response.
Hope this helps.
I am new to eventBus() function in SAPUI5.
I am using eventBus.publish() in Table.view.js controller to publish data & have used eventBus.subscribe() in MainPage.view.js controller. It is working fine.
But while I try to implement eventBus.subscribe() in another controller ("Feed.view.js"), it is not working. Why is it so?
The cause of you problem is likely one of the following:
You are not using the same EventBus in all cases (e.g. in one case
you use the sap.ui.getCore().getEventBus(), and in another case you
use your component's oComponent.getEventBus())
You are not using the same channel
You are not using the same event ID
Please check this, and if it doesn't help post more of your code.
I'm trying to build my Parse iOS project in a way that'll be more easy to migrate later on for the client should he desire it.
To that end, I'm trying to use the REST API instead of relying on PFUser and PFObjects.
But I love the PFLoginViewController-- it's such a time saver. Is there a way I can use that pre-built login/sign-up flow with the REST API instead of PFUser?
I don't think that u could use it without PFUser but u could create similar to that and time will be consumed.
Still One thing might work out, check this link and I hope you have already but this will show how to integrate the PFLoginViewcontroller so in that they have logInView which will provide you access to all component like loginButton, usernameTextField, passTextField and etc. So you could access to these component your own explicit component.
Like, you could create your own UIButton(namely, logInBtn with action selector and all) then access it to logInView.LogInButton = logInBtn(your own button) and in this button's action you could make Rest api calls for login, and similarly for other component which needs to be modified for your requirement.
I'm creating an external service of my rails app. This is always listening a rabbitmq queue and all their messages should be redirected to some methods of the rails controllers.
I've tried these approaches:
AMQP subscriber inside Rails app
What's the correct way to run one controller action from another controller action without an HTTP redirect?
http://www.misuse.org/science/2007/07/24/firing-rails-controller-actions-from-command-line-console/
The first one allowed me only to access the model (Anyway I suppose must be the base for what I want). The second one... never worked for me. And the last one doesn't works on rails 3 ( ActionController::Integration doesn't exists)
I think that the last approach still could be used if I figure out how the sessions are handled in rails 3. In any case, somebody had tried something similar before? Any suggestion will be appreciated.
Why not just send the request via an HTTP request? Your controller basically makes actions visible via URLs - simply making a request to the URL is essentially the same as calling the controller code, and it keeps your code working like a software service/API. You could even just use curl to do this if you want.
Otherwise, if the two files are in the same machine/folder, you could try to explicitly include the one controller code in the other, but that seems like maybe not the way to go. Depends on how you want the end result to work.
