kandi X-RAY | pry Summary
Pry is fairly flexible and allows significant user [customization] It is trivial to read from any object that has a readline method and write to any object that has a puts method. Many other aspects of Pry are also configurable, making it a good choice for implementing custom shells. Pry comes with an executable so it can be invoked at the command line. Just enter pry to start. A pryrc file in $XDG_CONFIG_HOME/pry/ or the user’s home directory will be loaded if it exists. Type pry --help at the command line for more information.

Using conccurrent-ruby, how can I execute a set of promises and then get the results?

QUESTION
I'am trying to load the iex.iexs
file when debugging a test. I created an alias
in Mix.exs
that tries to import it.
ANSWER
Answered 2022-Mar-15 at 19:58Note the file name should be .iex.exs
. As you have noticed, running tests does not start an IEx
session, so the file is not loaded. Instead, it might be better to do whatever setups you need for tests inside your tests/test_helper.exs
file. If you really need to re-use the settings/shortcuts in your .iex.exs
file, you can include it from your test_helper.exs
file something like this:
QUESTION
When I decrypt my string with the correct password following this simple guide on the library's website I get a correct string response. When I change the final w to an e to get an invalid key, I get a padding bytes error like this stemming from:
lib/python3.8/site-packages/cryptography/hazmat/primitives/padding.py", line 101, in _byte_unpadding_check
Which is then followed by the cryptography.fernet.InvalidToken error I was expecting.
ValueError: Invalid padding bytes.
During handling of the above exception, another exception occurred:
cryptography.fernet.InvalidToken
I've read Stackoverflow and can only find one example of this but it didn't seem to apply when this is just the actual example from their site.
What am I missing?
...ANSWER
Answered 2022-Mar-03 at 19:56Details about the structure of the Fernet key, the Fernet token and the algorithms involved can be found here.
The Fernet key consists of the concatenation of a 16 bytes signing key and a 16 bytes encryption key, Base64url encoded.
For the posted valid Fernet key is:
QUESTION
Can anyone please explain to me why my code doesn't run when I have my second elsif
statement in. I'm sure it's something simple but I've been over it a few times, wrote out the code again and still can't work out the bug. It only bugs when line 25 to 30 are in and says
undefined method`[]' on line 35
but this error will change to something else if I run it again.
So this is affecting line_three
as a test I am trying "Southern Cross" for the starting location and "Windsor" for the destination.
This is an error message I receive:
...ANSWER
Answered 2022-Feb-10 at 11:59In your line_three
Array, you have forgotten the comma between 'Prahran'
and 'Windsor'
. As such, Ruby parses this as a string continuation and adds a single element as 'PrahranWindsor'
here.
With that, none of your if
or elsif
conditions match. Consequently, note of the variables you set on any of the branches will be set and instead will be implicitly initialized as nil
. As you assume these variables to be set later in your program, things break.
To fix this, you should at first fix the definition of your line_three
array.
You should also add code to handle the case that none of your queries matched. Here, you could add a final else
branch which e.g. shows an error message and asks the user to try again.

QUESTION
I use ransack gem and I have a select field event_id
which can be either a string or an array, eg: 90 or [ 145, 147, 148 ]
The code I have, returns an error when an array is passed in:
...ANSWER
Answered 2021-Nov-18 at 12:15If you look over Ransack's Search Matchers you will see one with *_in - match any values in array
, which is what you need if you want to search in arrays.
Because your event_ids
can come in either as a string or an array and *_in
requires and array, we have to make sure we always feed it an array.
