kandi X-RAY | goop Summary
The Goop (Go Object-Oriented Programming) package provides support for dynamic object-oriented programming constructs in Go, much like those that appear in various scripting languages. The goal is to integrate fast, native-Go objects and slower but more flexible Goop objects within the same program.

QUESTION
There are a number of questions related to parent/child and many-to-many relationships, but I couldn't quite find one that seemed to make sense for my needs.
I have a database of "samples", let's just consider it some kind of goop in a bucket. Each sample has an associated ID. What I'd like to capture is that any given sample can have a parent (i.e. one sample can be split into multiple new samples by pouring the bucket into a bunch of smaller jars). Additionally, one sample could have multiple parent samples; create a new jar by combining multiple parent samples. The key here is that the child and parent samples represent the same thing (a sample) and should thus be members of the same table.
I started with a samples
table, where the columns are id
, date
, project
and parent
. The id
is an alphanumeric ID (i.e. A0001
, A0002
) and the parent
is an array of ID's that should refer back to the list of samples. In other words, the parent must be a member of samples
.
I wasn't able to set a foreign key relationship between id
and the list of id
s in parent
.
Is there a way to do this?
I thought about creating a parents
table, but then I might have something like:

Answered 2021-Jan-17 at 09:23Often when talking about relationships, a child has only one parent -- even though this is not quite the way that human relationships work. The canonical example is a tree structure.
You seem to just want a directed graph. That suggests two tables:
samples
sample_id date project A0001 2020/11/01 alpha A0002 2020/11/01 beta A0003 2020/11/05 gamma A0004 2020/11/05 gammaAnd
relationships:
parent_sample_id child_sample_id A0001 A0003 A0002 A0003 A0002 A0004- edit * I've fixed the missing
0
in thechild_sample_id
table above.
QUESTION
I am making a SSR react contentful application and after I hydrate the app correctly I am getting an error related to the data I got correctly from the server. It thinks the key I am passing to the contentful API does not exist but it did for the server request. I can't quite figure out why it would throw this error this way. Has anyone run into this the code is here minus the keys for obvious reasons.

Answered 2020-Oct-13 at 16:00The problem is that while the server-side rendered tree passes siteInfo
to , the clientside bundle's
index.js
does not. If you were running a development build of React, you'd probably see errors related to the hydrated tree differing from the DOM. You'll need to pass the initial props to the client somehow - one popular trick is to inject them into a global variable and pass that, for example:

Answered 2020-Oct-08 at 16:20Instead of rotating, could you just redraw it based on a horizontal/vertical orientation?
I created two bound functions below to return x, y, width, height, and radius values based on the orientation.
Every 2 seconds it will render in alternating orientation.
Edit: I cleaned up the code to self-document all the variables and even applied an overall background fill.
QUESTION
I've googled for a while now but I'm unable to find any solution for this.
So I have a bunch of files in a folder, and in this folder I have subfolders.
I want to move those files to the subfolders if they match any of these.
Like this:
- some random text yellow bananas more text.txt -> \yellow bananas
- some other text red apples this is text.txt -> \red apples
Example - files:
- Propulsion_mål_2020.jpg
- Axevalla Vivid Wise As Goop.jpg
- Dagens stjärna Cyber Lane.jpg
- 640px Elian Web heat.jpg
- ...
Example - directories:
- Propulsion
- Vivid Wise As
- Cyber Lane
- Vitruvio
- ...
Target:
- 1st file goes to 1st directory
- 2nd file goes to 2nd directory
- 3rd file goes to 3rd directory
- 4th file match no directory and goes nowhere
Is it doable?
Btw, it's possible that more than one subfolder matches the filename. If so, it doesn't matter which subfolder the file is moved to.

Answered 2020-Jul-24 at 21:46here's one way to do the job ... [grin] there is nearly zero error checking or handling, so you may need to add that. nor is there any record of what was done/not-done.
what it does ...
- sets the constants
all one of them. [grin] - creates the files & dirs to work with
when you are ready to work with your own data, remove the entire#region/#endregion
block. - gets a list of the dirs in the target location
- creates a regex OR of the names of those dirs
- gets a list of files in the target dir
- iterates thru those files
- tests for a match of the
.BaseName
property of each file against the dir name regex from earlier - if YES, creates a full dir name & moves the file
- if NO, writes a warning to the warning stream
that is on by default, so you otta see it when such a file is found. - finishes iterating thru the file list
