fluent | Fluent mapping driver for Doctrine2

kandi X-RAY | fluent Summary
This mapping driver allows you to manage your mappings in an Object Oriented approach, separating your entities from your mapping configuration without the need for configuration files like XML or YAML. This is done by implementing the LaravelDoctrine\Fluent\Mapping interface, or extending the abstract classes provided with this package for an easier use: LaravelDoctrine\Fluent\EntityMapping, LaravelDoctrine\Fluent\EmbeddableMapping or MappedSuperClassMapping. This package provides a fluent Builder over Doctrine's ClassMetadataBuilder, aimed at easing usage of Doctrine's mapping concepts in Laravel. The builder adds syntax sugar and implements the same grammar that you might use in Laravel migrations.

QUESTION
I'm having issues with understanding Fluent API when it comes to multiple entities owning one class.
Error:
...ANSWER
Answered 2021-Jun-14 at 15:07- Why do you need to derive from Entity? these are POCO classes.
- User and City have one-to-many relationship, right? then City needs to have list of Users.
- In one-to-many entities it is typical to have ID field in addition to object itself. So, City would have CountryId.
Probably, put your DbContext class as well. And "Entity is just a parent with an ID". Huh? and how this ID will be generated - in addition to CityID, CountryID, etc.? You are really asking for trouble
Advice. I usually create a database with all the tables and foreign keys - and then run scaffolding to get the baseline of objects. Simplifies a lot!
Then start with that model, and make the needed changes, if any. Based on your code, I am not even sure that you will need any changes!

I am trying to use Fluent Assertions on C# outside of test frameworks. Is there any way I could cast an FA check to bool? For example I need to achieve something like:
...ANSWER
Answered 2021-Jun-10 at 19:57Fluent Assertions is designed to throw exceptions that testing frameworks catch, not to return values.
About the best you can do is to create a method that accepts an action, and that catches the exception when the action throws. In the catch
you'd return false

QUESTION
Simply put: I want to list the last N packages I've installed with Homebrew.
What is the best (and possibly fastest) way to accomplish this?
Note that I'm not fluent in Ruby, so any suggestions to 'hack the Homebrew code to do what you want' would get me nervous...
What I tried so far- Read man pages, documentation, the Homebrew website, StackOverflow, googled with all sorts of variant questions, etc. No luck so far.
brew info [formula|cask]
will actually tell the date when a formula/cask has been poured (which I assume means 'installed' outside the Homebrewosphere). So that value must be written somewhere — a database? a log?- Maybe there is an option to extract the poured date information via the JSON API? But the truth is that with Homebrew 3.1.9-121-g654c78c, I couldn't get any
poured-date
or similar element on the JSON output... the only dates that I get are related togit
(presumably because they're more useful for Homebrew's internal workings). This would, in theory, be able to tell me what are the 'newest' versions of the formulae I have installed, but not the order I have installed them — in other words, I could have installed a year-old version yesterday, and I don't need to know that it's one year old, I only want to know I've installed it yesterday!
Although I couldn't figure out how to retrieve that information, I'm sure it is there, since brew info ...
will give the correct day a particular formula was poured. Thus, one possible solution would be to capture all the information from brew info
and then do a grep
on it; thus, something like brew info | grep Poured
should give me what I want. Needless to say, this takes eternities to run (in fact, I never managed to complete it — I gave up after several minutes).
Of course, I found out that there is a brew info --installed
option — but currently, it only works with JSON output. And since JSON output will not tell the poured date, this isn't useful.
A possibility would be to do it in the following way:
- Extract all installed package names with
brew info --installed --json=v1 | jq "map(.name)" > inst.json
- Parse the result so that it becomes a single line, e.g.
cat inst.json | tr -d '\n\r\[\]\"\,'
- Now run
brew info --formula
(treat everything as a formula to avoid warnings) with that single line, pipe the result in another file (e.g.all-installed.txt
) - Go through that file, extract the line with the formula name and the date, and format it using something like
cat all-installed.txt | sed -E 's/([[:alnum:]]+):? stable.*\n(.*\n){3,7}^ Poured from bottle on (.*)$/\1 -- \3\\n/g' | sort | tail -40
— the idea is to have lines just with the date and the formula name, so that it can get easily sorted [note: I'm aware that the regex shown doesn't work, it was just part of a failed attempt before I gave up this approach]
Messy. It also takes a lot of time to process everything. You can put it all in a single line and avoid the intermediary files, if you're prepared to stare at a blank screen and wait for several minutes.
The quick and dirty approachI was trying to look for a) installation logs; b) some sort of database where brew
would store the information I was trying to extract (and that brew info
has access to). Most of the 'logs' I found were actually related to patching individual packages (so that if something goes wrong, you can presumably email the maintainer). However, by sheer chance, I also noticed that every package has an INSTALL_RECEIPT.json
inside /usr/local/Cellar/
, which seems to have the output of brew info --json=v1 package-name
. Whatever the purpose of this file, it has a precious bit of information: it has been created on the date that this package was installed!
That was quite a bit of luck for me, because now I could simply stat
this file and get its creation timestamp. Because the formula directories are quite well-formed and easy to parse, I could do something very simple, just using stat
and some formatting things which took me an eternity to figure out (mostly because stat
under BSD-inspired Unixes has different options than those popular with the SysV-inspired Linux).
For example, to get the last 40 installed formulae:

Answered 2021-Jun-06 at 05:31The "brew list" command has a -t option:
Sort formulae and/or casks by time modified, listing most recently modified first.
Thus to get the most recent 40, you could write:

QUESTION
This is my first post here so please be forgiving :)
Just at the beginning, I'm not fluent in any programming language, but I mostly use SQL, very rarely VBA. I'm mainly RPA Developer with Kofax Kapow RPA software.
So I have a SQL query that I need to run to get some results that gonna be later used in RPA bot. There is a built in functionality to run SQL within RPA software but this functionality is very poor and doesn't allow me to use many functions that are embedded in my SQL query (like regex,listagg, exc.)
So what I would like to do is to run quickly VBA code without opening any SQL sotware. The best option for me would be to create kind of .exe file from for example MS SQL Server oraz Oracle SQL where this exe would result in creating a separate file (xls,XML,csv or any other) with the results
I know that sometimes like this is possible within a Excel VBA macro but I have some problems with excel macros within RPA software, since sometimes there is a yellow bar popping up at the top of the file and you need to "enable content" to run the macro. When I switched it and this bar doesn't appear, the macro didn't work too. This bar and things like this make a RPA bots less stable
So, hopefully I have described the issue here pretty well :)
Do you know how I may make this things (this file) happened ?
...ANSWER
Answered 2021-Jun-04 at 08:18Unfortunately you are not very clear in your problem description, but I go from what I can understand.
So you must run an SQL query and you must first construct this query?
You can use VBA to construct a query string in which you use VBA to embed the parameters into the string. For example, the parameters are in the Excel sheet, and you create one query string from each row.
Then you can either print these strings to a text file that you then can use in your SQL environment, or you use ODBC in Excel VBA to connect to your database, run each query, retrieve each query's result and print them or place in an Excel sheet.
Does any of these possibilities help you?

QUESTION
I want to turn off ALL (or at least most of) conventions in Entity Framework Core (and I am talking about EF Core 5 or above) and then build the whole model "by hands".
One may wonder why.
Here is why: I have a task to migrate several large legacy databases from Entity Framework 6 (EF
) to Entity Framework Core 5 (EFC
). This involves many hundreds of tables and several databases. Some of these databases are created using a Code First approach and some are just third party databases, which we need to query and update from C# code. For the latter databases we must match their schema exactly.
Due to the size of the problem both EF
and EFC
flavors of the code must coexist for, let's say, several months. This can be easily achieved by using conditional compilation (see below).
Most likely anything that is not supported or is inconveniently supported in EFC
in comparison to EF
(or was "hacked" into EF
models), like spatial indexes, multi-column KeyAttribute
PKs, multi-column ForeignKeyAttribute
FKs, self-referencing multiple times tables, multiple indexes defined on the same columns (some are filters and some are just regular indexes), and so on and so forth is there.
That's fine. I can easily deal with EFC
inability to deal with that by "overriding" the attributes using conditional compilation, e.g.

Install fluent
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.
