globalize | Rails plugin designed to support | Application Framework library

Generally speaking, in your .where method you should use the real table name, not the relationship's name between your models, so try with:

Redeclaring a variable in an inner scope creates a new variable.

I found a solution to handle pagination button count globally

Assuming in your parent component you're correctly initializing FormGroup in controller and using it correctly in template, you have two main errors in your component.

First, as Belle Zaid says, you should remove ngModel from you custom datepicker's .

Second, you are binding doInput() to (input), but it will fire only if you type in your input field, same for (change). You should bind to (bsValueChange) that's an output event exposed by BsDatepicker and it's safer, unless you plan to update value on user's input.

The resulting template will look like this:

You can probably use the techniques described here: Insert variable into global namespace from within a function?

I'd imagine it will require some bookkeeping in the __enter__ and __exit__ functions in order to clean up after itself. This isn't really something standard, so there my be some other foot-guns that I'm overlooking.

Since you tell that value can change for different process you just use properties

There are a number of layers that are used in the communication process and depending where you tap into that stack will depend what coding you need to do. The other complication is that BlueZ (the Bluetooth stack on linux) changed how it works over recent times leaving a lot of out of date information on the internet and easy for people to get confused.

With two Bluetooth devices, they need to establish a pairng. This is typically a one off provisioning step. This can be done with tools like Blueman or on the command line with bluetoothctl. Once you have a pairing established between your RPi and the M5Stack Stick, you shouldn't need to discover nearby devices again. Your script should just be able to connect if you tell it which device to connect to.

The M5Stack stick is advertising as having a Serial Port Profile (SPP). This is a layer on top of rfcomm.

There is a blog post about how this type of connection can be done with the standard Python3 installation: http://blog.kevindoran.co/bluetooth-programming-with-python-3/

My expectation is that you will only have to do the client.py on your RPi as the M5Stack Stick is the server. You will need to know its address and which port to connect on. Might be some trial and error on the port number (1 and 3 seem to be common).

Another library that I find helpful for SPP, is bluedot as it abstracts away some of the boilerplate code: https://bluedot.readthedocs.io/en/latest/btcommapi.html#bluetoothclient

So in summary, my recommendation is to use the standard Python Socket library or Bluedot. This will allow you to specify the address of the device you wish to connect to in your code and the underlying libraries will take care of making the connection and setting up the serial port (as long as you have already paired the two devices).

Example of what the above might look like with Bluedot

For anyone else bumping into this, the multi_fetch_fragments gem has been merged into rails 5 itself and so the line

You wouldn't normally convert a string to a function name directly, even if with Python just about anything's possible. However, functions are just objects so just use a dict:
