I had the following idea: my page at example.org serves classic HTML from the server. Besides, EmberJS is loaded, too, and waiting to come into action:
as soon as somebody hits an ember route then, for example example.org/#/login, the current should be replaced by what the view renders for it. From then, the whole app should serve as one-page-app.
Is that a good idea? Anyway, I don't know how to get that started. Overriding View's appendTo method or setting the rootElement property as in http://emberjs.com/guides/configuring-ember/embedding-applications/ does not suffice because if that were the body, the view output is just appended there…
If your entire Ember application requires a user to be logged in, it is valid to have two separate "apps":
A regular non single-page application (server-side using rails, PHP or C#) with a sign up and login pages
A single-page application (i.e. Ember) send as soon as the user hits the login button in your regular app
You will have 2 index.html pages, one for each application (and it's okay to do that!). The URL of the Ember App could be under example.org/app/.... You will need to configure the router of the regular application to server your Ember App for all URLs starting with /app/.
Does that help? :)

Is there a way in django to update the same page with the response without totally rendering it. I am trying to create a code editor to test. But when I am returning the results my contents are removed. I understand it is because I am rendering the page . I need the contents to retain. How can I do it using redirect? I am including the render statement I used and a screenshot of how it looks here:
Steps:
Handle post request
Program execution code
Save the result in a variable called "message". Then I used
return render(request, 'editor.html', {'message': message})
I want to redirect the message to the same page without rendering a new page.

Any help will be appreciated. Thank you.
it is possible. using ajax in front-end and render or render_to_string in back-end(Django). using ajax you're able to call a url (with/without data you want to send), then in the views.py you can do anything needed and return render(request,'template.html, context). then in ajax you have success: function (res) { $('#id_of_element').append(res)}. this function in ajax will append the recived response which is a rendered HTML template to the target element.
For that, you have to switch to a different web software paradigm called "single page application", which implies that both, backend and frontend, are functional software components on their own, instead of having a "dumb" HTML frontend that only displays what the backend renders.
In a regular web application, the front end is served from a backend with all the information that is going to display. In a Single Page Application, the front end is served by a server independent of the backend server, and the frontend and backend interact through an API served by the backend.
With this architecture, the frontend component is responsible for requesting and providing data from and to the backend, as well as for displaying the data and getting user's interaction, and the mean for interchanging data with the backend is called an ajax, that is an asynchronous request.
The only language accepted by web browsers is javascript, but there are many frameworks and second level languages that can render a javascript application, like React, Angular, Vue, and many others.
Folks,
I am pretty sure I am not the first one to stumble on this problem. But somehow I am unable to find any relevant resources out there.
Here is my issue, I have a backend in Django and my front completely written in Reactjs- React Router - Redux (nice combo right).
when entering the url webhost.com/, django provides me with a page with links to a bundle that is my whole react application and different stylesheets
The problem arise when I want to refresh a page, the browser still tries to query the server even though a route exists in my react-router configuration.
I had a look at the answer here (catch-all option) React-router urls don't work when refreshing or writting manually , but I don't quite understand it and I am afraid to have a new redux state everytime Django will provide the user with a new page.
You can setup up a wildcard url pattern that will render the same view that gets rendered when a request is sent to webhost.com. I don't know if that's going to retain your store though.
This is a pretty newbie question. However, in EmberJS, I've found that both of the methods work for linking to the blog page in my application.
<p>{{#link-to 'posts'}} See my blog{{/link-to}}</p>
See my blog
Is it better to use {{link-to}} in EmberJS? How come?
The difference is that the {{link-to}} component will navigate to the specified route within the current running Ember application, while <a href="posts"> will do a new browser request to that location and re-start your Ember app at that route. You should use {{link-to}} since you'll be using the Ember internals to navigate within your single-page application and it will be a smoother user experience.
While they both can work, watch your browser closely and you'll see the anchor tag will give you a page refresh and re-launch your Ember app (though in the right location). Using a {{link-to}} will feel faster since Ember is presenting the new page via javascript rather than restarting after a page refresh. It's the difference between navigating within a single-page application, and jumping into a SPA from an external page.
While Ember does render an anchor tag in place of the {{link-to}} at run-time, it interjects to stop the default anchor tag behaviour. The docs explain it like so:
By default the {{link-to}} component prevents the default browser
action by calling preventDefault() as this sort of action bubbling is
normally handled internally and we do not want to take the browser to
a new URL (for example).
(from https://emberjs.com/api/classes/Ember.Templates.helpers.html#toc_allowing-default-action)
Also, with the {{link-to}} component you can pass a model directly into the route. This is a bit more advanced, but the Ember guides have some good examples.
https://guides.emberjs.com/v2.13.0/templates/links/
I've done some example apps in Ember, and now I'm ready for using it in existing application. Its traditional web application (request-response, full reload and some ajax loaded content, no rest/api things)
So lets assume I've few page (urls) like
1 abc.com/home.php
2. abc.com/support.php ,
3. abc.com/support.php?call=meeting
and so on..
so is it possible to use just one url with ember app and rest leave as such untill its ready?
PS: I did try for support.php as this.route("support",{path:"/support.php"}) and have SupportController and support.hbs template but its not working. I'm not sure how to put it in jsfiddle.
Thanks
Include your ember app only on the page that needs it, so only on abc.com/support.php
As far as ember can see, when you go to abc.com/support.php you are on the index page (of the ember app), and you will need to use the index.hbs tempate.
I'm using ember1.0-rc3, i want to change hashbang urls into normal url format (ie, www.site.com/admin#/page1 to www.site.com/admin/page1).In order to make this change,i use location: "history" in app router.
But when i reload a page or bookmark a page doesn't works, it redirects to home page only.I want the options reload and bookmark in my app, without changing redirect urls in .htaccess file.Is there any way for it?Thanks in advance
In order to use HTML5 history with a single page app like ember, your server must be have the behavior of rendering your main index.html file for any URL. The Ember router has the logic to look at the URL when it loads and go to the correct route.
