            There are two issues in your attempted code.

            One is a fatal error that wouldn't even let you get close to the @... names. Specifically, the context path $.[*] is invalid. What you need there is $[*]. Your top-level structure is an array, and the path must reflect that. There should be no period between $ and the array marker [*].

            The second is - and this answers your question - that the names with a leading at-sign must be enclosed in double-quotes.

The code has no problem, although when I attempt to run npm install or yarn install to get the node_modules and the yarn.lock I get a weird error and the packages don't work.

            After facing similar issues on some of our workstations, I would say that it definitely looks like a bug in Node 14.18.x on m1 Macs and/or Big Sur (even though node itself is compiled for x86_64). I suspect a linking issue with the zlib library, but this is a discussion for Node's issue tracker...

            So here's my suggestion: uninstall Node 14.18.x and try using Node 14.17.x instead.

            As a side note, you may find it useful to first install nvm. nvm allows to quickly install several versions of Node, and switch from one to the other. For example, you might do:

            QUESTION

            In ASP.NET Core how do you get a scoped service instance in a non-controller class?
            Asked 2022-Mar-18 at 05:05

            In an ASP.NET Core 3.1 website I am attempting to use constructor dependency injection in a class that is not a controller and it doesn't seem to work as expected. The MyService.cs doesn't seem to get the class instance and throws an error... which requires me to pass it from the controller instead of just doing dependency injection in the constructor as expected.

            Some notes to clarify: The MyService.cs is a collection of Business Rules and not a service I am trying to inject (aka a business service). All I am trying to do is access the DataAccessLayerInterface DataAccessLayerService instance that was declared in the Startup.cs. The problem is when I try to use dependency injection in the constructor it doesn't work and throws a compile error. If I do the same exact thing in a controller though it works which baffles me.

            Eventually I plan to build this out as a data layer but for now I am just passing a single string with the intent of building it out later. Below are the relevant parts I have been working on. For brevity I stripped out namespaces and using statements references. I am using Microsoft.Extensions.DependencyInjection where applicable though.

            Change the value of a dataframe column to the value of a second column conditional on the value of a third column in pandas
            Asked 2022-Mar-06 at 07:05

            I have data with current names of companies, old names, and the date of name changes. It looks like this:

            name former_name1 name_change_date1 ACMAT CORP nan NaT ACME ELECTRIC CORP nan NaT ACME UNITED CORP nan NaT COLUMBIA ACORN TRUST LIBERTY ACORN TRUST 2003-10-20 MULTIGRAPHICS INC AM INTERNATIONAL INC 1997-03-17 MILLER LLOYD I III nan NaT AFFILIATED COMPUTER SERVICES INC nan NaT ADAMS RESOURCES & ENERGY, INC. ADAMS RESOURCES & ENERGY INC 2005-04-01 BK Technologies Corp BK Technologies, Inc. 2019-03-28

            I want to figure out what the name of each company was at a particular date. Let's say I want to figure out the name of a company as of January 1st 2002. Then I could create a new column called say, edited_name, which would contain the current name of the company unless the company has changed names since 1/1/2002, in which case it would contain the historical name (i.e. former_name1) of the company. So the output should look something like this:

            name former_name1 name_change_date1 edited_name ACMAT CORP nan NaT ACMAT CORP ACME ELECTRIC CORP nan NaT ACME ELECTRIC CORP ACME UNITED CORP nan NaT ACME UNITED CORP COLUMBIA ACORN TRUST LIBERTY ACORN TRUST 2003-10-20 LIBERTY ACORN TRUST MULTIGRAPHICS INC AM INTERNATIONAL INC 1997-03-17 MULTIGRAPHICS INC MILLER LLOYD I III nan NaT MILLER LLOYD I III AFFILIATED COMPUTER SERVICES INC nan NaT AFFILIATED COMPUTER SERVICES INC ADAMS RESOURCES & ENERGY, INC.
