You are writing message.text into the database inside the photo function. However, that function is only triggered for messages containing a photo. When the message contains a photo, message.text is None. Any caption the photo might have will be in message.caption.

How to get the data from a selected value in a view .NET Core API?

I'm creating an application where the user can post information and see the information posted, something like a forum. I created a list where the publications stored in the database are shown, so on the main page that list is shown with the title, description, date, etc. of each publication. Now, what I'm trying to do is select anyone of the posts in the list and then display the full information of the selected post in other view. I'm using a MVC view with its respective controller to consume the API.

QUESTION

How would you set up a database to handle comments for a blogging site?

Asked 2021-Jun-15 at 19:59

I'm a student learning about database design and currently learning about the relationships of - one-to-one, one-to-many, many-to-many. I understand the concept well enough, but feel like I'm lacking experience/information on how it would be implemented in a real production scenario.

My question is this

If I have a blog website with a Blog Post as an entity and comments for each blog post, how would you handle the comments in the database?`

Would you use a one-to-many relationship and just store all the comments in a single table. Then link those comments to each blog post and user who created it?

What if each comment had a sub-comment? Would you create a separate table for sub-comments and link it to a single comment? Would that cause too much overhead and confusion within the DB itself?

I get the concepts and all, but don't understand best practices for handling what seems like basic stuff.

Thanks in advance!

...

ANSWER

Answered 2021-Jun-15 at 16:06

The simplest solution is to stick with a one-to-many relationship. Use one table and store one comment per row, with references to the post and the comment author, and a timestamp so you can sort the comments chronologically.

You seem uncertain about whether you need a "threaded comment" hierarchy. This is more complex, so if you don't need it, don't bother.

If you do need to show comment threads, then you should learn about running recursive queries in MySQL 8.0: https://dev.mysql.com/doc/refman/8.0/en/with.html#common-table-expressions-recursive

You still only need one table. Don't create a second table for sub-comments. Just store comments like in your one-to-many example, but each comment may link to its "parent" comment when it is a reply.

Another solution that many sites use is to skip implementing their own comment system, and just embed a comment service like Disqus. That's likely to be much more reliable and safe than yours. But if you're doing this as a learning exercise, that's worthwhile too.

QUESTION

Is there a way to do conditional select statements in SQLite?

Asked 2021-Jun-15 at 19:54

I am trying to create an app in which the user has the option to query the database by entering information into one of two entry boxes. I want to be able to use a single select statement and conditionally query the database based on what box the user enter their information into. I currently am trying to use a CASE clause, but I believe that it is running into an error when I try to include a WHERE clause in the THEN argument. Here is what I am currently working with:

QUESTION

Managing nested Firebase realtime DB queries with await/async

Asked 2021-Jun-15 at 19:34

I'm writing a Firebase function (Gist) which

Queries a realtime database ref (events) in the following fashion:

await admin.database().ref('/events_geo').once('value').then(snapshots => {
Iterates through all the events

snapshots.forEach(snapshot => {
Events are filtered by a criteria for further processing
Several queries are fired off towards realtime DB to get details related to the event

await database().ref("/ratings").orderByChild('fk_event').equalTo(snapshot.key).once('value').then(snapshots => {
Data is prepared for SendGrid and the processing is finished

All of the data processing works perfectly fine but I can't get the outer await (point 1 in my list) to wait for the inner awaits (queries towards realtime DB) and thus when SendGrid should be called the data is empty. The data arrives a little while later. Example output from Firebase function logs can be seen below:

10:54:12.642 AM Function execution started

10:54:13.945 AM There are no emails to be sent in afterEventHostMailGoodRating

10:54:14.048 AM There are no emails to be sent in afterEventHostMailBadRating

10:54:14.052 AM Function execution took 1412 ms, finished with status: 'ok'

10:54:14.148 AM

Super hyggelig aften :)

super oplevelse, ... long string generated

Gist showing the function in question

I'm probably mixing up my async/awaits because of the awaits inside the await. But I don't see how else the code could be written without splitting it out into many atomic pieces but that would still require stitching a bunch of awaits together and make it harder to read.

So, two questions in total. Can this code work and what would be the ideal way to handle this pattern of making further processing on top of data fetched from Realtime DB?

Best regards, Simon

be aware I don't have a Windows machine against which to try this, so it's just "best effort"

As best I can tell, your problem is because you are trying to recreate the behavior of win_shell by "manually" invoking that improperly quoted cmd.exe /c business, ending up with cmd.exe /c "cmd.exe /c whatever"; dialing up the ansible verbosity -vv could confirm or deny that pattern

Also, the win_shell docs say to use win_command: unless you have a shell redirect need, which as written your task does not.

VBA - NULL values in Listview

Asked 2021-Jun-15 at 17:10

I've created a simple VBA interface to connect Excel to a MySQL DB. The VBA part acts as a preview of data for the user to choose what item he wants to import to the Excel sheet.

Until now I've work with a very complete set of data, but I got to a Table which (because of the nature of the items) some fields are NULL.

Now every time I try to check the values in the VBA I get the Run-time error 13 Type mismatch in the listview component. At first I though it was a field with DECIMAL typing, but after changing it to a DOUBLE (for testing) the problem persisted, and it was until I notice that if only checks columns with no NULL value, the problem disappears. Off course I can't omit this values.

I tried some .Tostring functions but with no success. And I failed to implement a IF to check for NULL in the obj.

This is my code:

If you don't want to add a IsNull-function in you SQL (as Nathan_Sav suggested as a comment): There is a IsNull-function in VBA. With that, you can create a simple function that returns for example an empty string (or a 0 or whatever you prefer):
