I have two sets of dataframe, one is the "gold" one which means that I need to keep all the rows for the gold one after merging. The other one is reference one. Below is a sneak peek of that two dataframe.
...ANSWER
Answered 2022-Feb-17 at 08:59I have the answer you want here. It generates an "output.csv" which you can read with pandas as a dataframe to give you the expected result.
Here is my "output.csv". The results look odd because your sample input (reference.csv and gold.csv) were a small subset. If you test on your full large input CSVs, you will get a proper output:

QUESTION
While save data in database got exception Cannot handle managed/back reference 'defaultReference': back reference type not compatible with managed type
. I got exception while persist data. I think problem is in @JsonManagedReference
or @JsonBackReference
annotation but can't findout the problem.
Here down is code:
Entity
...ANSWER
Answered 2022-Jan-19 at 08:43@JsonManagedReference
together with @JsonBackReference
are supposed to be used in bidirectional relationships of OneToMany
in one side and ManyToOne
on the other side, or when both sides are of type OneToOne
.
If you inspect closely the JsonBackReference Doc you will understand this
Value type of the property must be a bean: it can not be a Collection, Map, Array or enumeration. Linkage is handled such that the property annotated with this annotation is not serialized; and during deserialization, its value is set to instance that has the "managed" (forward) link.
In your case you have bidirectional ManyToMany
which means that in both sides there is a reference to a collection. So there is not a single compatible property on the side that you have @JsonBackReference
.
There are 2 solutions in your problem with ManyToMany
relationship
- Remove both
@JsonManagedReference
and@JsonBackReference
. Pick a side where you want the collection to be serialized and deserialized. Go to the other side where you don't want the other collection to be serialized and deserialized and use the annotation@JsonIgnore
. - Use custom Dtos which do not have circular dependencies and let your controller use those Dtos instead of plain entities.
Also you have another problem as well

QUESTION
I've recently been teaching myself python and instead of diving right into courses I decided to think of some script ideas I could research and work through myself. The first I decided to make after seeing something similar referenced in a video was a web scraper to grab articles from sites, such as the New York Times. (I'd like to preface the post by stating that I understand some sites might have varying TOS regarding this and I want to make it clear I'm only doing this to learn the aspects of code and do not have any other motive -- I also have an account to NYT and have not done this on websites where I do not possess an account)
I've gained a bit of an understanding of the python required to perform this as well as began utilizing some BeautifulSoup commands and some of it works well! I've found the specific elements that refer to parts of the article in F12 inspect and am able to successfully grab just the text from these parts.
When it comes to the body of the article, however, the elements are set up in such a way that I'm having troubling grabbing all of the text and not bringing some tags along with it.
Where I'm at so far:
