I'm developing a web app which is a kind of ecommerce. So I want to develop a kind of message board for every item that is on sale.
It would be something similar to that (http://netdna.webdesignerdepot.com/uploads7/building-a-threaded-comment-block-with-html5-and-css3/demo/), whit a section at the end for posting your own message (as Facebook, something similar to that: http://sportscommunity.com.au/wp-content/uploads/2012/12/fbcomments.jpg).
After the press of the button the page will be updated and your message will be shown.
The problem i'm facing is showing a message posted by another user meanwhile you're on the page.
When the page is loaded all the message related to the item are loaded too and showed automatically. Messages are stored into a NDB GAE database.
My question is: how can I update the content of the page when a new message (written by a user that's is not me, and related to the item's page i'm looking) is stored into the NDB GAE database?
Any suggestion?
I'm not looking for a chat, but something more similar to the comment section of a Facebook's post: not updated in real time, but in reasonable amount of time and automatically.
I hope I have explained my problem well
I would have recommended the Channel API, but I just discovered that it is being deprecated.
Instead, Google is recommending their Firebase Realtime Database.
With this or any other web channel, you will need to write some client-side code (probably in Javascript).

I am creating an ecommerce webapp and I want to update my admin page when user place order. After research i found out about Django signals, but it seems pretty confusing. The idea behind this is that, when a user places an order I want the admin page to be refreshed and show the latest updates. I tried ajax but javascript can only work with the current open page. Can anyone help me with usibg django signals this way?
I think you misunderstand a little, if your idea is that the admin page viewed by the user in a browser is to be refreshed. The page viewed by a site visitor is retrieved on demand of the browser. The user could refresh a page, or a page script may auto-refresh on a timer (this is not a very good solution, but it is easy).
Django can't make the browser update the page.
Signals can cause django to do something in the backend, but they can't solve the problem that the browser is in charge.
There is one technology designed to allow the server to push content to the browser: websockets.
If you use websockets (Django's fairly recent built-in support is called Channels (https://channels.readthedocs.io/en/stable/)), then you can push content to the browser, where a receiving script on the page will do something with it. This is a very powerful technique, but there is a learning curve of some hours if you are starting from scratch.
Recently I came across this front-end library which tries to make this easy as
far as the browser goes: https://htmx.org/docs/
But you still have to deal with running a websocket server and learning how to send messages to a websocket. You will however feel like a superhero at the end of it, so there's that.
Take a breath... it's a very specific question, not directly a bug.
(But I can't get an answer from Facebook, after thousands of FAQ pages I somehow landed in a chat with Facebook Advertisers Support, they told me to come here.)
Description of my app
I have a Facebook Page, on which I'm sharing events from some other Facebook Pages I'm cooperating with. Kind of an event aggregator. The main goal is to help people who are new in town to find all that interesting events and the groups and pages they are organized by.
As you can imagine, it's based on a server-side application, that collects the upcoming events through Graph API and posts on my own Facebook Page the day before the event.
Of course I had to give the server-side application the manage_pages and publish_pages right. This Facebook App will never be used by an end-user, I'm the only user and I'm only posting to my own Facebook Page.
The server-side application worked fine for more than a year.
I just started a Facebook Ad Campaign and poster and flyers are currently being printed. And now...
What broke
You all heard of Cambridge Analytica. Due to these bad guys Facebook is currently changing a lot. One change was this:
As we begin enhancing our new app review process and make changes to our platform, the Events, Groups, Pages and Instagram APIs will no longer be available to new developers. Testing of our more robust process starts today and the new process should resume in a few weeks, but apps currently accessing Events and Groups APIs will lose access today. Going forward, access to these APIs will require a formal app review and for apps using the Pages API, submission is required within 90 days once app review resumes or access will be removed.
(See https://developers.facebook.com/blog/post/2018/04/04/facebook-api-platform-product-changes)
Since nearly two weeks my server-application can't fetch events. Graph API is always returning an empty array data: [].
I have full understanding for this. Now I tried to follow these new requirements and had a look on how to submit my App for review. But that's where my struggles began:
The specific problem
The whole form for applying for review is aimed to Apps for end-users, not server-side bots.
I should provide details on why I'm using manage_pages or publish_pages. Well okay...
When selecting "automated posting" there immediatly a message pops up, telling me, that this is not allowed. Of course it is not - for applications that post in the name of persons without their knowing and aggreement. But my App is posting in the name of my own Facebook Page and I'm the only user and I'm knowing what's going to be posted. So I have to select "Other" and enter a custom description. No problem.
But at the end of the form there's asked for a Screencast! What should I make a movie of? Should I make a slideshow of my code? I can't save this form without that Screencast.
I want to be conform to the new Facebook processes, but I simply don't know how to become approved nor at least fill out for review...
I know this is not a programming question but Facebook directed me here.
So I hope I find a Facebook official or Facebook developer here. Thank you so far!
The start-up i currently work for is oriented around restaurant wait times. For our v1.25 specifications our clients -restaurants- that have Facebook pages want to be able to communicate to their app profile from their Facebook page.
The closest i have came to answering this question is the Graph API. However, the Graph API only allows us to read and write data to FB pages. So, is there a way for a restaurants FB page to write to its app profile? Secondly, Loso, whom we have modeled some of our designs from has this ability, does anyone have an idea as to how they have done it?

Here is an option that you can consider...
When you are designing the app you can also develop a page tab to go with it...
You will find this option in the basic settings of the app.
You can make it to install for all first time users of your app, by getting a list of all his pages he created using that profile then install it on the one he selects.
This page tab when installed on a page will appears just where other tabs on the page appers(e.g. events, notes etc. occurs)
You can provide your required functionality on this tab as you like.
Thus the user can just select that tab on the page and use its functionality to post on the profile page of the app.
Hope this works for you... and also u can check out the jobcaster app it does something like that!
I'm developing an app which publishes actions to the timeline.
On the app settings, I've created the action "post" and use the built in object type "article".
Although my graph actions have not been approved by facebook, that should not be a problem, because I am logged in as the developer of the app.
My article URLs pass facebook's linter with warnings, but no errors.
When my app notifies facebook of the the post action, it appears to succeed. Facebook returns an ID representing the action.
When I use facebook's graph explorer to view that ID, the data appears to be correct, showing the correct action type and object data. (If there's a URL to browse the action on facebook, instead of the graph explorer, I do not know what it is).
Still, with all the above apparently working without errors, I never see the action on my timeline. Whether I browse my own timeline, or when logged in as a friend and another developer of the app, I never see any indication on facebook.com that the action was performed.
What am I missing to make my custom action appear on my timeline page?
I had a similar problem. I was using OG and I could post everything successfully, but the posts didn't appear in timeline, but only in the activity log in Facebook.
I just went to the settings of the action and set "Explicitly Shared: This action can specify the user explicitly shared an action." to ON.
Then in my piece of code I put "true" to the key "fb:explicitly_shared" while creating the OG object.
If no error is being returned it sounds as if there is an issue in your public page that is preventing Facebook from knowing what to post.
Have you double checked your OG: meta tags through Facebook's validation tool [ https://developers.facebook.com/tools/debug ]. While you need all of the values to be filled in, the type bit is the most overlooked and must be setup properly to link to your particular application and corresponding action.
If your OG: data is correct and validating you should also check the detail settings for your action and aggregations. If the phrase / tense bits are not filled in Facebook may be uncertain how to make your post appear back to on the timeline.
Discoverd the problem....
My article page include an article:author tag. The URL in that tag was not visible to anonymous users. So, I'm guessing, facebook visited that author URL and received a HTTP 403.
When I removed the article:author tag, the items started appearing on my timeline.
So be careful with all tags and put all urls through facebook's debug tool.
Hmmm Interesting
Was having the same issue...
Using the XFBML, fb:like with all required og meta tags validating on the linter.
Last month when I liked a 'product' on my website, the post was published on my fb timeline wall no worries. Nice, perfect!
Today after clicking Like, I noticed it wasn't publishing to my timeline wall at all... but was logged in the Activity Feed.
It did however post to my wall if I commented on the Like Button flyout comment section.
Then I found this
"Pages of type article do not have publishing rights, and will not show up on user's profiles because they are not real world objects."
https://developers.facebook.com/docs/opengraphprotocol/#types
I've been getting the same issue with a feed dialog post. The posts can be navigated to directly, but doesn't show on timeline. More details here:
Actions not appearing on timeline
I had a similar problem, but everything was actually working correctly. If you get a returned ID and your article appears in your RECENT ACTIVITY, then all should be good.
The perceived issue, your post not appearing in your timeline, is actually the correct behavior. Your post doesn't appear in your timeline because it should appear in your friends' timeline as an activity that you completed. Once they comment or like it, then it should reappear on your timeline.
For me the issue was the posts doesn't show on timeline for all users except me also it was public !, i fixed it by make turn on application as online to be available to all users
I recently put a django project of mine into its beta stages and would really like to integrate more with social media, particularly facebook.
Now there are so many facebook integrations out there... I don't know where to start but, I'll tell you what I am after.
My sites publishes content with photos and also user related data (which site doesn't)
on each individual page I already have a facebook like button that basically has the absolute url of that page
so for instance:
http://my-site.com/url-1
http://my-site.com/url-345345
http://my-site.com/url-456456456
When a user likes this particular url I would like them to become a Fan on my facebook site/page as well.
I also added the FB opengraph tool which is a bit more informative once a user likes it. But it still does not publish any statistics to my page.
Can someone give me a bit of an understanding on what the best option is for this type of integration?
As a security option for the user, Facebook has never allowed third party access to "become a fan."
If you want to record locally when someone presses the "Like" button, you'll have to implement it locally (copy the presentation, and query Facebook yourself), so you can intercept the event. I've done that; it's not too hard.
I suggest you review the Connect Terms of Service to see what it is you're allowed to do: http://developers.facebook.com/policy/
