screencasts | The translated captions of my screencasts | Functional Programming library

I have a "belongsToMany" eloquent relationship between users and roles . I am creating a CRUD system with capability to do bulk actions. I followed the Livewire Screencasts Bulk Export/Delete and Refactoring For Re-Usability. I have created a trait for the bulk actions, so I'm able to use it out of the box.

I need to detach the role from the user and then delete the user in bulk. I am unable to call roles relationship on a public method property and detach the same. This is how I detach the role for a single user $this->user->roles()->detach(); but I'm unable to do it with $this->selectedRowsQuery->roles()->detach(); in case of bulk user deletion.

I am making a component based data table I have a Table component:

I've been having issues with the layout of nodes. I copied this observable https://observablehq.com/@d3/clustered-bubbles and it works great for smaller nodes, but seems to get really distorted for bigger nodes.

I'm using this in a react app with typescript. I don't have a working snippet to use because the data is a large number.

These are some screencasts of the issues experiences: https://share.getcloudapp.com/lluJnbWl https://share.getcloudapp.com/jkuQYBpq

It doesn't force them into their groups properly and the animations don't work so good.

This is my code, if someone can see if I'm missing something to update/fix:

My website uses Facebook Page API to pull public content from a Facebook page, published by the page owner, to create a dynamic blog with a clear link to the Facebook page.

You can see it here in action: https://kc-hrubeho.cz (ctrl+F "Facebook"). Yellow button "Načíst další" works as an AJAX pagination. Sorry for the Czech language, this website unfortunately does not have an English version.

I'm using this URL to get JSON object of the page content: https://graph.facebook.com//feed?access_token=&limit=10&fields=message,link,attachments,created_time,full_picture,picture,timeline_visibility

Right now it works, but App review FAQ states this:

My app used to access public content on pages, am I affected by the v3.0 changes?

Yes. Apps that access content of public pages need to request Page Public Content Access feature and require review by Facebook.

Also, there is this notice:

In order to maintain your current API access, your app will need to be submitted for review by August 1, 2018.

I've filled out the form for review. One of the required items is "the screencast".

We need to see your app using Page Public Content Access so we can see that it doesn't violate our policies. Upload a video screencast walkthrough using any method, (even recording with your phone). You must show:

1. How a person logs in with Facebook
2. How a person sees this feature used in your app

More detailed instructions about the screencast state this however:

You do not need to submit your app if it will only be used by you or by a reduced number of people. Any account listed in the Roles tab in your App Dashboard, such as admins, developers and testers, can access all permissions and generate a user or page access token.

You can use any of these accounts to test your app and create a screencast.

This is incredibly confusing. My questions are:

1. If my code access the Pages API and shows the result on my website, is it "used by reduced number of people"?

2. If I do not need to create a screencast, how can I apply for a review? Do I even need it (meaning "will my token work after 1st August")?

3. If I do need a review with a screencast, what exactly should I record in my case? Should I just stitch a few screencasts of my code and the website to a single video? That, imho, sounds just bonkers. :)

4. Is there a different endpoint all together (which would not require a review or the screencast) that I should use, if I only need to read the data of my own page?

5. My old applications are working right now (not sure about August 1, see above). For applications with the same purpose (just to read public content of FB page owned by the owner of application) created after all the fuss with reviews, will there be the same rulset as is for the old ones?

Thanks in advance!

This is what I've heard from the group moderator of official FB support group Facebook Developer Community:

You can use an app in dev mode to retrieve the feed for pages you are admin of. [...] I don't know if August 1 will change the current behavior or if the current behavior is even the intended behavior. [...] Actually I never met a person that was able to predict what will happen in 90+ days ... most experts even fail to predict tomorrow's weather ;) Seriously, I don't know ...

Very frustrating, but so far the most specific answer I got.

I feel like this should be an easy thing to do in Rails, but all of the examples of nested forms in Rails do not take into account the fact that most nested forms also need to pass the current_user when creating new objects through a nested form.

The only way I can get this to work at the moment is by passing a hidden field such as <%= form.hidden_field :user_id, value: current_user.id %>.

For my specific example, I have a model called "Result" that has many "Lessons" and I'd like to create new lessons through the Result form without passing a hidden :user_id.

This seems unsafe because someone could edit that hidden field in the browser and then submit the form thus associating the submission with a different user. The current_user.id seems like the type of thing you don't want to embed in the html as a hidden field.

So how do you create the association between the nested objects and the current_user without putting that hidden field in the form?

FYI, I'm using the GoRails nested form with stimulus style javascript to add and remove lessons from the result form. (Here's the source code for that example.) Here are the relevant parts of my code:

I am looking at how to animate colors in react native and followed this tutorial https://codedaily.io/screencasts/8/Animate-Colors-with-React-Native-Interpolate

All I have done is first run react-native init then replace the code in my App.js with this

I am trying to learn to record X11 windows' contents to do game screencasts for Youtube. This should be a fairly trivial task, but it already ate a full evening. Now I have learned a bit about muxing and queueing (using gst-launch), but the problem remains: When I mux an audio and video into an avi, video plays several times faster than audio in the resultant file. This means that video ends soon and comes to still, while audio continues to babble in the background.

This is my filter chain that causes the issue:

Consider the code below from here and here.

My question:

• What is the benefit of arrange(desc(Median)) if there is an fct_reorder(Major, Median) beneath it?

I'm getting this error:
