QUESTION
I'm new to Yii2 and returning to PHP dev after a very long time. I have an extensive background in Java development. I stumbled onto this recommendation in the docs for ActiveRecord:
__construct()public methodDefined in: yii\base\BaseObject::__construct()
Constructor.
The default implementation does two things:
- Initializes the object with the given configuration
$config.- Call init().
If this method is overridden in a child class, it is recommended that
- the last parameter of the constructor is a configuration array, like
$confighere.- call the parent implementation at the end of the constructor.
My question is about the last sentence:
call the parent implementation at the end of the constructor.
As a Java dev, this advice seems very weird to me. In Java, not only is it recommended to call the parent constructor as the very first call from your overridden constructor, this is even enforced and it's actually impossible to do it any other way. Either your parent constructor is called first implicitly, or, if you make an explicit call, it MUST be the very first statement in your method. This is enforced by the compiler.
Theoretically, this makes a lot of sense to me. Because as long as you did not call the parent constructor, your parent class did not have the chance to initialize, so any code you write in the constructor before calling the parent constructor would be working with a half-initialized object.
Looking at some SO answers I found, they seem to be going against the advice in the official docs and call the parent::__construct before their own custom logic, as I would expect it. For example, the accepted answer in the question How can I create a constructor in a Yii2 model shows an example where they call the parent first:
ANSWER
Answered 2022-Apr-02 at 06:21@michal-hynčica correctly stated the reason for your ambiguity(Worthy of votUp).
But since you mentioned that the official reference, on the same page (BaseObject), this issue is explicitly stated: line
- In order to ensure the above life cycles, if a child class of BaseObject needs to override the constructor,
- ....
- of the constructor, and the parent implementation should be called at the end of the constructor.
According to the description of this link (similar to your question):
init () is called which further calls bootstrap () to run bootstrapping components.
As a result, this is done to ensure configuration.
The same process is done in the controller class and the main module.
Of course, there are many examples like this on the php site (depending on the need)
Also read lifecycles and entry script in yii. components and structure-applications. Good luck
QUESTION
I'm having trouble understanding how to write concurrent async code encapsulated in one single structure.
I'm not sure how to explain the problem exactly, so i'll try to do it with an example.
Let's say I have a UdpServer struct. This struct has multiple methods related to its behavior (e.g, handle_datagram, deserialize_datagram, etc)
If I want to make the code concurrent I will spawn tokio task, which requires closure provided to it to be static, which means that I can't call &self from within this task as long as &self is not static, which means that i can't call self.serialize_datagram().
I understand the problem (there is no guarantee the struct will outlive the thread), but can't see a proper way of solving it. I know it's possible to just move the function out of impl, but this doesn't look like a good solution to me.
Also, even if we assume for a moment that i could take &self as static, this code still doesn't look right to me for some reason (Not Rusty enough, i guess).
Another "solution" is to take self: Arc instead of &self, but this feels even worse.
So I'm assuming there is some pattern I'm not aware of. Can someone explain to me how should i refactor the whole thing?
Example code:
...ANSWER
Answered 2021-Nov-15 at 12:59Currently the only way to do it is to make self last arbitrarily long through the use of Arc. Since run() is a method on UdpServer, it requires the change to Arc, which you considered but rejected because it felt worse. Still, that's the way to do it:
QUESTION
I have two geodataframes: One containing sightings of animals of a specific species called bird_df (with location as points), and the other detailing the boundaries of each municipality within my state called map_df.
I want to use the geopandas method .contains(x) to count the number of animals that were found in each municipality and add that total to the boundaries dataframe so i can generate a choropleth.
My pandas is a bit rusty but I've tried things like
map_df[map_df["geometry"].contains(bird_df["geometry"]) == True]
I just don't know how to wrap my head around this problem. Some help would be appreciated.
Thanks

I need to verify if there is a line where these 2 matches are met in the respective .txt :
- Line of the file named
file1.txtthat is equal to the input string1"old apple". - Line of the file named
file2.txtthat is equal to the input string2"on the floor".
For example, file1.txt have these lines:
ANSWER
Answered 2022-Feb-28 at 08:37In your code you only check if the strings are present in the respective lists, you don't check if the corresponding line numbers match. But even if you would check, your code is likely to produce an erroneous output because of how .index works. To quote from here:
list.index(x[, start[, end]])Return zero-based index in the list of the first item whose value is equal to
x. Raises aValueErrorif there is no such item....
You only get the first index. So, if there's no line number match for the respective first finds, you'd be stuck.
If you're only interested in if there's a match then you could do something like this instead:

Is there a way to "inject" a default type for a template member function of a template class "after" the definition of said template member function?
Basically similar to this (which does not compile), so that I can specify NS::Default (the default type for Z) outside of the library in which template class S and its member function template are defined:

Very new/rusty with TCL here :-(. I am stuck with tcl 8.6 and can't take advantage of tcl 8.7 feature of getwithdefault on a dict.
Tried the following and get error saying "frameLen" is not part of the dict. But I thought the ternary operator should have skiped the part on [dict get $pktBlock frameLen]. What did I do wrong?
Thanks!
ANSWER
Answered 2021-Dec-22 at 18:26Turned out I had a wrong spelling. I intended to have dict exists $pktBlock frameLen but ended up using framelen.
Case is VERY important. Hope this could be a lesson for those who are stuck

Install Rusty
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.
