QUESTION
This is my first attempt at parsing nested JSON with Ruby. I need to go through the JSON to pull out specific values for "_id", "name", and "type" for instance. I then need to create a reference table so that I can refer to each "_id" and associated information. I also need to combine information from multiple JSON responses. I've been able to get basic information and have tried a few things I've found online. I just need a little assistance with a starting point. If anyone has any ideas of where to start with this I'd really appreciate it.
Devices JSON response hash. Each device starts with _id.

I have a problem sending a picture to a server, that's like the default approach, but it does not seem to work.

Answered 2020-Nov-03 at 06:24In Formdata when you pass files, you need to pass 3 parameters where
- key expected from the backend (in your case
image). - It will be an object which has three properties named
name,type, anduriwhere type is themime type(ex:image/jpeg). - name of the file
Eg:
data.append("FilePath",{ name:"image.png", type:"image/png", uri:"content://com.camera/image.png" },image.png)

I am reading about implementation of state machines using variants. I try to create a construction that take a variant parameter to initialize the state. However whent the constructor is defined , I get a warning that this is recognized as function declaration.
Moreover when I try to define a setter for the state, compiler error is generated when try to call this
Here is the code

I would like construct a class composition that includes a function set_props for setting the instance variables of components.
The application for this is in defining new objects for drawing in matplotlib. One example is that I would like to have a function drawMyArrow that draws an arrow with possibly different colors (and other specifications) for its head, tail, and arc. I would like to be able to pass various specifications for the head, tail, and arc via keyword arguments in drawMyArrow. I haven't worked with classes before, but reading up on this online, I believe that the best way to solve my problem is to define a class MyArrow that is a composition of some classes ArrowHead and ArrowArc.
To illustrate my problem, I am using a toy example (that I also used for a previous question here). Let's define a class Room that is a composition of the classes wall, window, and door.

I have two dataframes of different row and column sizes. I want to compare the two and create new columns in df2 based on whether values exist in df1. First for an example (I think you can copy/paste this text into a .csv to import), df1 looks like this:

Answered 2018-Aug-11 at 19:28You can do this by using melt on df1 and merge.

QUESTION
I'm struggling with quite a specific issue. I have two pandas dataframes of different lengths with different indexes. For each item contained in df1, I want to look into df2 and take a couple of columns (not contained in df1), where the values of one of the df2 columns are equal to those in df1. Example:
...ANSWER
Answered 2017-Sep-16 at 07:49You can outer merge the data by renaming the column and then rename the columns with your desired column names and then fill the nan of produced_values with dropped and drop the nans. At last set the df1 index.
QUESTION
I'm using javaxsmartcardio at the moment but I don't know how this library works. I have an acr122u reader/writer and I only want to use it as writer so that I can write cards and read them on my RFID doorlock project with rdm6300 card reader. So far I've managed to read 2 cards which both were written to be used in social utilities. That's why I've written my arduino code according to 1 card is autherized and the other is not. But I want to write my own cards and put my own specific password so only the cards I give autherization will unlock the door. I'm all set with the doorlock part but I'cant write my own cards.Please help me out. Thanks in advance.
...ANSWER
Answered 2017-Jun-08 at 17:13Mifare uses 13.56 MHz. The RDM6300 is 125 KHz.
You'll need to replace one to be compatible with the other for your project.
