kandi X-RAY | Nest Summary
Nest is a PHP class that lets you easily get and set values in nested arrays and objects without worrying about errors or missing data. You don't have to check if keys, properties or functions exist. It's all designed to fail gracefully. Need a value from an array that is returned by a function that requires parameters on an object which is stored in an array? Nest will get it for you, or return a default value if the one you want isn't there. Easy. You can get and set nested values. You can iterate over them with foreach. The only limitation is that you can't set the value returned by a function because, well, it's obvious. ####When you could do this?. You don't have to worry about any key checks, or checking if things are set... Just fetch the value. You can specify a default value (null by default) to use in case the one you want isn't there. Focus on building great apps instead of validating data. ####Use a string as the path parameter. ####We're going two levels in this time, so use an array for the path. ####What if we try to get something that isn't there? Does it error?. ####Or we can specify our own default in case of error.

QUESTION
I'm attempting to write a scraper that will download attachments from an outlook account when I specify the path to folder to download from. I have working code but the folder locations are hardcoded as below:-

Answered 2021-Jun-15 at 20:37You can do this as a reduction over foldernames using getattr to dynamically get the next attribute.
QUESTION
I simply want to surface an Exception message as a bad response in DRF.
The Exception can come from anywhere in the request. So for example, some nested function can have:
raise Exception('Something went wrong at this particular point')
And then in my view handler, i'd simply catch the Exception and raise it:

A typical way to use group_by and then nest is to estimate a series of models--

Answered 2021-Jun-15 at 19:23We can add ungroup in between as the nest_by returns with rowwise attribute which clashes with the map

I am querying a database for an item using R2DBC and Spring Integration. I want to extend the transaction boundary a bit to include a handler - if the handler fails I want to roll back the database operation. But I'm having difficulty even establishing transactionality explicitly in my integration flow. The flow is defined as
...ANSWER
Answered 2021-Jun-15 at 18:32Well, it's indeed not possible that declarative way since we don't have hook for injecting to the reactive type in the middle on that level.
Try to look into a TransactionalOperator and its usage from the Java DSL's fluxTransform():
QUESTION
I am trying to create scatter plots of all the combinations for the columns: insulin, sspg, glucose (mclust, diabetes dataset, in R) with class as the colo(u)r. By that I mean insulin with sspg, insulin with glucose and sspg with glucose.
And I would like to do that with tidyverse, purrr, mappings and pipe operations. I can't quite get it to work, since I'm relatively new to R and functional programming.
When I load the data I've got the columns: class, glucose, insulin and sspg. I also used pivot_longer to get the columns: attr and value but I was not able to plot it and don't know how to create the combinations.
I assume that there will be an iwalk() or map2() function at the end and that I might have to use group_by() and nest() and maybe combn(., m=2) for the combinations or something like that. But it will probably have some way simpler solution that I can not see myself.
My attempts have amounted to this:

So I have this object which has other objects and array nested inside it. I want to create a function that lists all the elements in this object and its nested objects.

QUESTION
I have two tables:
- Car_company which has the attributes of: C_id (primary key), C_name
- Car_model which has the attributes of: Com_id (referenced to C_id of Car_company), Model_year Warranty
I wish to access both of these tables individually and also I would like to perform a join operation on them and display all of the car_models along with their car_company name. I tried using both JPQL and native query but nothing worked. I also made sure to use the OneToMany and ManyToOne associations but I ended up getting infinite nesting,i.e, the models have car_company as field, this inturn has car_models as a list, and this keeps going. Please help me with entity classes and DAOs.

Install Nest
PHP requires the Visual C runtime (CRT). The Microsoft Visual C++ Redistributable for Visual Studio 2019 is suitable for all these PHP versions, see visualstudio.microsoft.com. You MUST download the x86 CRT for PHP x86 builds and the x64 CRT for PHP x64 builds. The CRT installer supports the /quiet and /norestart command-line switches, so you can also script it.
