ANSWER
Answered 2021-Aug-14 at 16:28This means that rowContent[header] is undefined.
Inspect rowContent - e.g. by placing a console.log(rowContent); after const rowContent = .... this should give you some clues and maybe log the header value inside the for loop.

53So I thought about making a script that would collect all of the resources per project and sotre the resources in a directory labeled by the project name. So I thought about wrapping a for loop to make directories named after the project names. I have tried the following and they have not worked:

56none of them seem to really work and instead of incapsulating it in a string it doesn't work and instead still splits the names apart like Network Development becomes Network and Development. How can I get this to work so it will account for any whitespace that might exist within the project names.
ANSWER
Answered 2021-Aug-06 at 15:04So unfortunately I couldn't use the regular for-loop syntax to achieve this. Instead I had to use a while loop (many thanks to Jetchisel on helping me acheive this outcome). The following method worked for me:

62QUESTION
How to Account for White Space and Append Strings in Double Quotes in Bash Script
Asked 2021-Aug-05 at 20:43Hi so I have a task whereby which I need to move over projects from one cluster to another. The only way I can do that is if I re-create the projects. I have a script that works and gathers the listed projects within a running OpenStack cluster, but I need to be able to take the file I store out and use it to re-create the projects.
Here is the script that gathers the available projects:

76Some of the projects have white spaces. However, I thought that with a for loop this would be easy to re-create.

77However, this did not work as when I used $i it did not account for white space, so essentially any strings that had spaces in between accounted for two strings. This means that when I iterated over it and tried to re-create it, it would take Ansible Automation and try to make a project for both Ansible and Automation. To handle this I can place the strings in double quotes

QUESTION
"statistics unavailable at this time" when trying to print String Pool information?
Asked 2021-Jan-04 at 20:35I am following a udemy course on java performance management and I am coming across an issue that is preventing me from printing out information for the String pool. This is what I get when I attempt to add ten million String objects to the pool:
1E:\IntelliJ Projects\ExploringStrings\src>java -XX:+PrintStringTableStatistics Main

55So, my question is: Why can't I print out information for the String pool when I attempt to add 10 million objects, but my instructor can? I am failing to understand the reasoning as this is pretty beyond my level of Java programming. Thank you all.

144After waiting to exit, the statistics unavailable at this moment message is gone, and we get full statistics.
We do indeed see Number of literals jump from a few thousand to over ten million. Presumably this is due to our loop of ten million numbers turned into strings.
I tried to research this, to learn the documented behavior of the PrintStringTableStatistics switch. But I cannot find any documentation. I have no idea where to find documentation nowadays for the console tools java, javac, and so on.
If anyone has a link, please post.
QUESTION
How to combine array of data and make is more easy to use
Asked 2020-Dec-22 at 12:46I am working with a filter that I can use after the search so that way I created a table in the database and insert some category and its sub categories and now I want to combine all of the to make a tree like structure. But I am stuck with this
Now How can I achieve this?
1[
2 {
3 "parent_category": "Recruitment",
4 "category_name": "Job description"
5 },
6 {
7 "parent_category": "Recruitment",
8 "category_name": "Forms"
9 },
10 {
11 "parent_category": "Performance management system",
12 "category_name": "Job description"
13 },
14 {
15 "parent_category": "Exit",
16 "category_name": "Job description"
17 }
18 ]to this type of result :
1[
2 {
3 "parent_category": "Recruitment",
4 "category_name": "Job description"
5 },
6 {
7 "parent_category": "Recruitment",
8 "category_name": "Forms"
9 },
10 {
11 "parent_category": "Performance management system",
12 "category_name": "Job description"
13 },
14 {
15 "parent_category": "Exit",
16 "category_name": "Job description"
17 }
18 ][
19 {
20 "parent_category": "Recruitment",
21 "category_name": "Job description, Forms"
22 },
23 {
24 "parent_category": "Performance management system",
25 "category_name": "Job description"
26 },
27 {
28 "parent_category": "Exit",
29 "category_name": "Job description"
30 }
31 ]Without using a long type of for loop because it consume more time.

42QUESTION
How to use update method in viewsets in Django Rest Framework and perform some task(like sending mail) along with it?
Asked 2020-Jul-23 at 12:25I am working on a simple performance management system with react on frontend and django on the backend. They are supervisors who can give reviews to supervisees and supervisees can respond. I want all employees to receive email when they receive reviews from their supervisors and all the supervisors to receive email when their reviews are responded. For reviews and responses I am using two different serializers but same model.
Serializer for Response is:
1class ResponseSerializer(serializers.ModelSerializer):
2 supervisor_name = serializers.SerializerMethodField('get_supervisor_name')
3 supervisor_email = serializers.SerializerMethodField('get_supervisor_email')
4 supervisee_name = serializers.SerializerMethodField('get_supervisee_name')
5 supervisee_email = serializers.SerializerMethodField('get_supervisee_email')
6
7 class Meta:
8 model = Review
9 fields = (
10 'id', 'review_text', 'response_text', 'date_of_review', 'date_of_response', 'supervisor', 'supervisor_name',
11 'supervisor_email', 'supervisee', 'supervisee_name', 'supervisee_email')
12 read_only_fields = ('review_text', 'date_of_review', 'supervisor', 'supervisee')
13
14 def get_supervisor_name(self, obj):
15 return obj.supervisor.first_name + " " + obj.supervisor.last_name
16
17 def get_supervisor_email(self, obj):
18 return obj.supervisor.email
19
20 def get_supervisee_name(self, obj):
21 return obj.supervisee.first_name + " " + obj.supervisee.last_name
22
23 def get_supervisee_email(self, obj):
24 return obj.supervisee.email
25For sending mail I am using send_mail method from django.core And I am using Viewsets for Reviews and Responses.
Now Response operation will always be an update operation because Response will always be used to update existing Review object in which response_text field will be updated.
1class ResponseSerializer(serializers.ModelSerializer):
2 supervisor_name = serializers.SerializerMethodField('get_supervisor_name')
3 supervisor_email = serializers.SerializerMethodField('get_supervisor_email')
4 supervisee_name = serializers.SerializerMethodField('get_supervisee_name')
5 supervisee_email = serializers.SerializerMethodField('get_supervisee_email')
6
7 class Meta:
8 model = Review
9 fields = (
10 'id', 'review_text', 'response_text', 'date_of_review', 'date_of_response', 'supervisor', 'supervisor_name',
11 'supervisor_email', 'supervisee', 'supervisee_name', 'supervisee_email')
12 read_only_fields = ('review_text', 'date_of_review', 'supervisor', 'supervisee')
13
14 def get_supervisor_name(self, obj):
15 return obj.supervisor.first_name + " " + obj.supervisor.last_name
16
17 def get_supervisor_email(self, obj):
18 return obj.supervisor.email
19
20 def get_supervisee_name(self, obj):
21 return obj.supervisee.first_name + " " + obj.supervisee.last_name
22
23 def get_supervisee_email(self, obj):

66AttributeError: 'NoneType' object has no attribute 'first_name'
67So, what is happening is due to some reason, all the fields of that particular review are getting set to null as soon as I try to update and hence getting NoneType object has no attribute. I have checked in database table(MySQL), all the fields are getting set to null. Can anyone tell me why is this happening ? Where am I going wrong ? And what is the correct way to do it?
ANSWER
Answered 2020-Jul-23 at 12:25Finally I found my solution by changing the method update to partial_update. Apparently update method updates all the field while in above case I am attempting the field called response_text in the Review model which are setting other fields to null if they could be. Also after doing that I had to change the request from PUT to PATCH in frontend. Also I had to do some other minor coding changes like removing supervisor and supervisee fields from read_only_fields from ResponseSerializer. Updated code for ResponseViewset is shown below:
1class ResponseSerializer(serializers.ModelSerializer):
2 supervisor_name = serializers.SerializerMethodField('get_supervisor_name')
3 supervisor_email = serializers.SerializerMethodField('get_supervisor_email')
4 supervisee_name = serializers.SerializerMethodField('get_supervisee_name')
5 supervisee_email = serializers.SerializerMethodField('get_supervisee_email')

105QUESTION
Is using 'ref' or 'out' common practice in C#
Asked 2020-Jul-23 at 07:14I was sticking on Unity for a while, without knowing much about Computer Science/Performance management.
Now, I took some C++ experience, with some concerns on IO/performance/etc some "Computer Engineering" stuffs.
Then I got back to my old Unity project, which had no concern about those thing at all, and found out that there is ref(or out) keyword for call-by-reference, as I could do in my C++ project.
Is it common to use ref(for call-by-reference purpose) of C# on 'business level'?(maybe game companies with Unity?)
ANSWER
Answered 2020-Jul-23 at 07:08If you come from C++ then you have this thought in your head that you need to pass references, because if you don't, the whole object will be copied and most likely that is bad (tm).
In C#, types are either reference types or value types. Reference types are passed by reference automatically. If you pass a class, it can be null, so it must already be a reference to the actual class instance (or in C++ terminology a "pointer", because references in c++ cannot be null).
All classes are reference types. You don't need ref or out for performance reasons ever. If you find yourself using ref or out for performance reasons on a struct, that should be your clue that it should be a class instead.
So no, using ref or out is not common in C# at all. It is only used sparingly, in the places where you would not get the desired result without it. Those keywords are not meant for performance considerations.
