QUESTION
I'm playing around with mock autospecs in Python. Here's a basic test case where I'm autospecing the Django User
class using create_autospec.
ANSWER
Answered 2021-Apr-25 at 22:30Consider mocking the int
class. int
is callable, like most classes, so a mock of the int
class should also be callable.
On the other hand, consider mocking an int
instance. Integers are not callable, so a mock of an integer should also not be callable.
The instance
argument lets you control which of these behaviors you get. create_autospec(int, instance=False)
returns a callable mock, while create_autospec(int, instance=True)
returns a non-callable mock. If you do

When you are using a GitHub action (you have uses:

do not support that.
What can you do?
As suggested in the borales/actions-yarn
REAME.md:
Please keep in mind that this Action was originally written for GitHub Actions beta (when Docker was the only way of doing things). Consider using actions/setup-node to work with Yarn. This repository will be mostly supporting the existing flows.
You can remove these actions and call yarn directly in run:

Answered 2021-Mar-21 at 17:02In the particular case you're asking about of why it might break Redux DevTools, there seems to be a section in the FAQ about this.
As with state, serializable actions enable several of Redux's defining features, such as time travel debugging, and recording and replaying actions. Using something like a Symbol for the type value or using instanceof checks for actions themselves would break that.

Answered 2021-Feb-25 at 15:40The setter and getter of Javascript are different from thos of Java. A typical pattern is that you define the instance variable with underscore _chaveDeAcesso
and after you allow access to that with setter and getter without the underscore like in the following code. These methods are on the prototype and are accessibile like that:
QUESTION
My website receives allows users to post a string that contains several Questions followed by multiple choice answers. There is an enforced style-guide that allows the results to be parsed by Regex and then Questions + MCQ choices are stored in a database, to be later returned in randomized practice exams.
I wanted to transition over to pyparsing, because the regex is not immediately readable and I feel a little locked in with it. I would like to have the option to easily expand functionality of my questionparser, and with Regex it feels very cumbersome.
User input is in the form of:

Answered 2021-Feb-10 at 06:51I think you were on the right track - I took a separate pass at your parser and came up with very similar constructs, but just a few differences.

Answered 2021-Jan-15 at 16:09You can totally have objects in state, and Redux Toolkit's use of Immer allows you to "mutate" those objects.
My answer in the other issue was pointing out that Date
objects are not inherently serializable, so you shouldn't be saving them in the Redux state.

QUESTION
I'm creating some kind of React layouting library that stores its current state in a Redux store. The library isn't just a styling thing, it has certain (for this question irrelevant) capabilities.
However, since it's a layouting library, the consumer of the library will provide what to render at certain locations.
The library would be exposed thru a single slice (with corresponding reducers, actions and selectors) that the consumer is supposed to simply inject into their root reducer.
π½ Current implementationCurrently, the way the library knows what to render is by the consumer providing the rendering function.
...ANSWER
Answered 2020-Nov-30 at 09:45The hint for the solution I've found is basically in the Redux documentation itself.
They suggest intercepting the unserializable data in the middleware and removing it from the action so that nothing unserializable ends up in the reducer.
In my case, it is totally fine if these rendering functions reside in the middleware.
The register
action will scrape the function, store it in the middleware and forward the action without it.
And since all the registers
should happen before the first render of the app anyway, it will work even with the redux devtools goodies.

Install style-guide
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.
