QUESTION
I have translated a program from javascript to python 3.9 and I am only missing sorting the result, but I just can't get any further.
The list consists of dicts that has an id "components", which is itself a list.

QUESTION
I am currently creating class diagrams in UML for a movie test domain. I would like to know if I am doing it right. Well, I have two alternatives (the first version in the first picture, the second in the second - I think the first one is better). I'm wondering if I've established the so-called "relationship owner" correctly, that is, from which class to which direction the relationships go. I also don't know if I didn't get multiplicity wrong (one to one, one to many etc.).
So on my domain I would like to have movies of course, the actors starring in those movies and directors. I wonder if the class name "Character" is good in this case, because I mean all the characters that take part in a movie - it can be director, actor but also for example "Batman". Maybe I should make a distinction here between "Movie Character" and then "Human", "Monster", whatever. But I don't know how to do it elegantly, will I then inherit from the Character class? I'm also wondering if I shouldn't put classes like City or Country together in one class called Address - but I wanted the classes to take attributes like in this case, that one is Master and the other is detail - and the relationship set in the right direction. I use only relations such as Inheritance and Dependency, I do not know if I should change something in this case.

Thanks in advance for any suggestions or advice!
...ANSWER
Answered 2021-Jun-15 at 11:58Use inheritance very carefully. Prefer association over inheritance whenever your inheritance is not a permanent truth from the birth to the death of an object. ANd keep in mind that dependencies between classes do not make any promises about objects of those classes.
Some more explanationsSome clarifications on the UML syntax:
- I understand that your plain thick lines ended with a small hollow triangle represent a specialization/generalization relationship (aka inheritance). If this is correct, the triangle should be larger to avoid visual confusion. Moreover multiplicity makes no sense with inheritance and should be removed.
- I understand that with the dotted line you intend to represent an association with multiplicity. If this is correct:
- the association should be plain lines, because dotted lines are for dependencies, and multiplicity would make no sense.
- the meaning you give to the arrow head would be unclear. Do you use them to document navigability? In case of doubt, remove them. If you want to document ownership of the association end, use the dot notation instead. (we cannot say if it’s right or wrong, since it’s a decision on how your model sees the associations)
In view of your comments and the third model linked therein, there are some key UML semantics you need to keep in mind:
- Inheritance is an ultra-strong relationship which means "is (always) a". In your example, you may say that an
Actoris always aPerson, and hence, everything you say about aPersonis also true for anActor. By the way, you should avoid repeating inherited properties or methods, since it could create some ambiguity. - Inheritance is not a substitute for aggregation, composition or association. You can for example not say that a
CrewMember(one person) is always aCrew(a group of persons). ACrewMemberbelongs to aCrewbut there are things that the crew can do together that the individual member can't. - Inheritance is not suitable if it's not always true. A
Characterfor example may often be aPerson. But not always;: you can have ghost characters, comic characters, robot characters, or animals. - Association means that there is some structural relation between some instances of the associated classes. For example, that one ore several persons live in one city, seems a very relevant assocaition.
- Dependency means that a class is dependent on another, i.e. without the other class it would not work or something would be missing. It's a statement about the classes and not the objects. I.e. If you meant to say that
Personis dependent onCityyou just say that the class Person would not work without knowing about City (for example, because the operationsendPostCardFrom(city: City)needs an argument of that type) but you do not say anything about persons X, Y and Z. If you want that X, Y and Z are related to city a, b, and c, you need an association.
About the model content, I'll not decide for you and there is no single truth. I therefore prefer to draw your attention at potential issues. I raise them in form of a question, up-to you to adjust the model based on your own answer:
Common issues between the both variants:
- Are
ActorandDirectorreallyPersons? In this case, what with the Persons that are Actors and Directors at the same time (g.g. Clint Eastwood) ? Or areActorandDirectorjust roles that aPersonstakes for a givenMovie? - Is a
Characterreally related only to 1Movie? What to do with Indiana Jones, where the same character appears in several movies? - In a similar way, I wonder if there's really a single
Personwho lives in aCityor if this should not be a many-to-many association?
- Are
Issues regarding the differences: `
- Is a
Personin version 1 aCharacter(inheritance) ? Or is aCharactera representation of aPerson(association: represents) ? - Is a
Characterin version 2 really anActorand by transitivity also aPerson(inheritance)? Or is theCharacteronly associated with anActor(association: plays) ?
- Is a
It's up to you to decide, but wherever I asked a question about association or inheritance, you should better think twice before using inheritance (i.e. prefer association/composition over inheritance)
QUESTION
I'm gathering text in form using textarea and I plan to render that text using .innerHTML so that the user can make the content bold, italic and underlined. I might decide to increase the flexibility to allow coloured text using style attribute as well.
I have considered using regex to match the text but I'm hoping for a more elegant solution.
This is what I currently have ...ANSWER
Answered 2021-Jun-15 at 10:22One approach is to convert all elements to text and whitelist elements you want to allow. With innerText the browser converts all html entities to their code. Then you can read actual code with innerHTML and replace whitelisted elements.
QUESTION
Sorting data from huge lists with two levels of keys is helpful for interpreting dataset and calling by couple or one level of keys some slice of data, especially when creating plots.
I use a very naive and, I guess, inefficient way to create from a 2D-list of data a dict of dicts (two levels of keys) that returns a list of data. How to make this code more elegant, possibly faster and more readable? I guess using collection module but I didn't find a smart way.

QUESTION
I am looking for some help concerning WordPress plugin development. My plugin queries an API which requires an Authentication Token, that token is fetched via a Token delivery APi. The token expire every 3600 seconds.
I would like to store the Token, in a persistent way (for all sessions , like server side caching) and update it only when needed. Multiple Api call could be done with the same token. The problem is, if I store the token in a global variable, it gets reset each time a user reload a page which uses my plugin. https://wordpress.stackexchange.com/questions/89263/how-to-set-and-use-global-variables-or-why-not-to-use-them-at-all
After looking for answer I found:
-WP_CACHE , but it is not persistent.
-I know I can store the token in the Database, but a Token in Database is not a use case I found elegant
-Tool such as Redis Object Cache for PHP but I found it to be really complicated , installing etc...
Is there any good practice or easy way of doing this? I only need to keep a string for an hour and access it within the plugin in PHP.
Thank you.
