kandi X-RAY | ribs Summary
The current ORM approaches for Ruby include ActiveRecord, DataMapper and RBatis. None of these have the versatility and power that Hibernate gives to any Java project. Ribs is a new interpretation of the idea ActiveHibernate, which was proposed in a blog post here[The original name didn’t really suit, though, since it was based on the ActiveRecord name, and Ribs will end up being something quite different. So what is Ribs? It’s a Ruby framework written for JRuby, that allows you to use Hibernate to persist your Ruby objects. There are many things planned for Ribs, but currently it only supports quite basic operations. Ribs is explicitly defined to solve several data access patterns for most Ruby development. In one end it means scaling down from something very much like ActiveRecord, but on the other end supports such things as Repository, Data Mapper, Unit of Work and Identity Map.

QUESTION
I am working on a project in which I need to post a new Course to my API. I tested this with POSTMAN and API works just fine, however when I try to post data using react fetch data is corrupted. While sending single strings like dishName: "pizza" works just fine and is shown in database I cannot manage to send an array of objects. I tried to do it in many ways like:
...ANSWER
Answered 2021-May-27 at 21:44You are setting the ingredients state as a string, so you are basically 'stringify' a string which will result in JSON SyntaxError. If you want to send an array that way you must specify the array bracket [ and ] in order to make it a valid array.
To solve it just change:

my first question, so please be patient with me...
I have this string:
"Create a script which will take a string and analyse it to produce the following stats. Spicy jalapeno bacon ipsum dolor amet kevin buffalo frankfurter, sausage jerky pork belly bacon.

QUESTION
When I set my browser window to a height of let's say 200px I have to scroll down to be able to see all the text in the left column of my page. I would like my background image to not only cover the viewport height, but to cover the complete page which has to be scrolled through, so that my layout does not break and the text is visible on top of the background image.
I'm doing an online course and it was explained that I can solve this problem by setting a min-height: 100vh. I've set this on .intro, .bg-image and .intro-content. My problem still occurs though.
Thanks in advance.
DEMO :
...ANSWER
Answered 2021-Apr-26 at 12:01As you already set your container .intro with height: 100vh;. You should just set on .bg-image, min-height: 100%; instead of 100vh;. This way the image will grow with a minimum height of your container.
The problem with putting always min-height:100vh; in a container with the same setting than you cannot add margin as you did because the block wont be contain by container anymore.
For the image to fit correctly with its sibling you should make the css as below.
otherwise the intro-content will be too long. I let you check the little change I made.

QUESTION
Not familiar with CSS Grid I'm trying to create a two column layout. Per reading tutorials it was suggested to use minmax() but for some reason I cannot figure out how to break column 1's full height that matches column 2, example:
ANSWER
Answered 2021-Apr-08 at 19:23You can't stop the columns being equal height but you can align the content of the columns so it does not achieve the default 100% height.
Note that the row will still have the same height but this has the visual appearance you seem to be after.
QUESTION
Fairly new to the world of Flutter and I've been searching for a built-in method that makes a partial match to one string value and an entire set of strings within a list. For example...
Let's say I am querying the string "Farmhouse Sides, Coleslaw".
...ANSWER
Answered 2021-Mar-23 at 07:37There are several ways to do this. One is very close to what you've done; however you need to call .toLowerCase() before matching the string. The other would be to use regex where you can tell it to ignore case.
Here's an example:

QUESTION
I have around 70 categories (it can be 20 or 30 also) and I want to be able to parallelize the process using ray but I get an error:
...ANSWER
Answered 2021-Feb-18 at 01:31This error is happening because of sending large objects to redis. merged_df is a large dataframe and since you are calling get_meal_category 10 times, Ray will attempt to serialize merged_df 10 times. Instead if you put merged_df into the Ray object store just once, and then pass along a reference to the object, this should work.
EDIT: Since the classifier is also large, do something similar for that as well.
Can you try something like this:
QUESTION
you're help is needed: the mystery is located in Method setupNumRibs.
In my test setup the table contains only one row.
...ANSWER
Answered 2021-Jan-31 at 17:30There is no mystery if you read the docs:
QSqlError QSqlQueryModel::lastError() const
Returns information about the last error that occurred on the database.
It is clearly indicated that lastError() indicates an error that happens when interacting with the database, but in your case it does not interact since the model first verifies that the QModelIndex is valid, and since yours is not valid then it returns immediately false without doing any transaction with the database.
On the other hand, don't complicate your problem by adding Singleton or other elements that are just noise. It would be recommended that for each question you create an MRE focused only on the problem and thus save us time to help you instead of having to eliminate silly code.
QUESTION
I'm scraping a website for product reviews. I can successfully get the JSON data, but I'm having an issue with the parsing. The levels of data are like this: payload -> reviews -> 22Y6N61W6TO2 -> customerReviews.
The data I want is in the "customerReviews level. However, the "6IYETQATGRMP" value will be different when looking at another item.
I don't want to have to use a different python script for each item to account for this one value. How do I use something like a wild card or something to get the data I'm after?
I'm using Python 3, requests, and JSON in my script.
My script looks like this:
