KeyError on chained callback for dependent dropdowns in plotly-dash [Python]

Asked 2021-Apr-16 at 01:20

I'm trying to create a dependent dropdown in dash/plotly, based on the unique values from the column depending on what is selected in the first dropdown. I created a chained callback and visually, the graph is updating correctly and the dropdowns are populating correctly. However, I receive an KeyError for one of my fields (Category, which has nothing to do with the dropdowns, it simply colors the categories), after a fair amount of tinkering I still can't figure out what's causing it. Here's my layout, callbacks and the error I'm getting in the debug environment:

edit: callback graph is showing an unwanted callback, I don't want graph update to be triggered until the options are updated (i.e. the path on the right). is there any way I can prevent this? callback graph

ANSWER

Answered 2021-Apr-16 at 01:20

So I have a workaround, I'm sure there is a better solution but this is working as expected. I believe the graph update_graph function is being triggered after the game dropdown is updated, but before the options are updated, resulting in the filter on wrcombo_ producing a blank table. After the 2nd callback, the error was fixing itself as the platform is updated and the table can filter correctly. Introducing a check if the table is empty allows me to decide whether or not to refresh the graph, as below:

def update_graph(game_slct, plat_slct):

wrcombo_ = wrcombo.copy()
wrcombo_ = wrcombo_[wrcombo_['Game']==game_slct]
wrcombo_ = wrcombo_[wrcombo_['Platform']==plat_slct]

if len(wrcombo_) != 0:
    print(wrcombo_)
    wrfig = px.line(wrcombo_, x='Date', y='Time', color='Category', custom_data=['Runner', 'Game', 'Notes', 'Category'], height=600)
    wrfig.update_traces(
        mode="markers+lines", 
        hovertemplate='<b>%{customdata[0]}</b><br>Time: %{y|%H:%M:%S} <br>Achieved on: %{x|%e %b %Y} <br>Notes: %{customdata[2]}'
        )

    return wrfig
else:
    return dash.no_update

As I mentioned, not sure this is optimal, as I am still having to filter the table first - so please let me know if there is a better way to do this. There is no need for the 3rd callback to trigger until the second one has, so disabling that is probably the missing piece of the puzzle.

QUESTION

Center element on window using transform

Asked 2021-Feb-23 at 09:26

I'm trying to center a card element when it is clicked, to highlight it and separate if from the other cards, using CSS transforms. I know CSS transform is relative to the element's location, but I have to use transform and not top/left to avoid repositioning of the other cards. I've tried to calculate the correct offset using JavaScript, like so:

const cardRect = cardElement.getBoundingClientRect();

const offsetX = window.innerWidth / 2 - cardRect.x - cardRect.width / 2;
const offsetY = window.innerHeight / 2- cardRect.y - cardRect.height / 2;

However that did not work, because the bounding client rect changes all the time, as I have a scale(1.1) on card hover.

So how can I move the clicked card to the center, without offsetting all the other ones?

The cards are created like so in the HTML:

<div class='container'>

  <div class='movie'>
    <img :src='/images/1.png'>
    <h3>Harry Potter and the Sorcerer's Stone</h3>
  </div>

  <div class='movie'>
    <img :src='/images/2.png'>
    <h3>Harry Potter and the Chamber of Secrets</h3>
  </div>

  <div class='movie'>
    <img :src='/images/3.png'>
    <h3>Harry Potter and the Prisoner of Azkaban</h3>
  </div>
  
  etc...

</div>

And everything is styled like so:

.container {
  display: flex;
  flex-flow: row wrap;
}

.movie {
  width: min-content;
  flex: 1;
}

.movie:not(.selected-movie):hover { /* .selected-movie is a class applied to the clicked card */
  transform: scale(1.1);
  box-shadow: 10px 10px 32px 0px rgba(0,0,0,0.4),
              -10px -10px 32px 0px rgba(0,0,0,0.4);
}

.selected-movie {
  transform: translate(offsetX, offsetY); /* Here are the offsets needed */
  flex: 0;
  display: grid;
  grid-template-areas:
      'poster title'
      'poster description';
}

Here is a JSFiddle showing the problem: https://jsfiddle.net/u6tpbjna/5/

ANSWER

Answered 2021-Feb-22 at 23:15

Some of your other CSS styles for .selected-movie were throwing off the un-selected cards' styles when the clicked movie is selected, so I've temporarily commented out those styles. Regardless, I believe this should answer the question you're asking about the using those offsets in the CSS.

This is a great opportunity to use CSS variables, which you can set on pageload and window resize using JavaScript. From there, everything else can be done in CSS.

See below:

const cards = Array.from(document.querySelectorAll('.movie'));

const setCardOffsets = () => {
  for (card of cards) {
    const cardRect = card.getBoundingClientRect();
    const cardOffsetX = window.innerWidth / 2 - cardRect.x - cardRect.width / 2;
    const cardOffsetY = window.innerHeight / 2- cardRect.y - cardRect.height / 2;
    card.style.setProperty('--offset-x', cardOffsetX + "px");
    card.style.setProperty('--offset-y', cardOffsetY + "px");
  }
}
setCardOffsets();
window.onresize = setCardOffsets;

document.addEventListener('click', e => {
  if (e.target && e.target?.matches('.movie, .movie *')) {
    const clickedCard = e.target.matches('.movie') ? e.target : e.target.closest('.movie');
    if (clickedCard.classList.contains('selected-movie')) {
      clickedCard.classList.remove('selected-movie');
      return;
    }
    cards.forEach(card => card.classList.remove('selected-movie'));
    clickedCard.classList.add('selected-movie');
  }
});

.container {
  display: flex;
  flex-flow: row wrap;
}

.movie {
  transform: scale(1) translate(0px, 0px);
  width: min-content;
  flex: 1;
  position: relative;
  transition: all 0.2s ease-out;
}

.movie:not(.selected-movie):hover {
  transform: scale(1.1) translate(0px, 0px);
  box-shadow: 10px 10px 32px 0px rgba(0,0,0,0.4),
              -10px -10px 32px 0px rgba(0,0,0,0.4);
  z-index: 2;
}

.selected-movie {
  transform: scale(1.1) translate(var(--offset-x), var(--offset-y));
  /*flex: 0;
  display: grid;
  grid-template-areas:
      'poster title'
      'poster description';*/
  z-index: 1;
}

<div class='container'>

  <div class='movie'>
    <img src='/images/1.png'>
    <h3>Harry Potter and the Sorcerer's Stone</h3>
  </div>

  <div class='movie'>
    <img src='/images/2.png'>
    <h3>Harry Potter and the Chamber of Secrets</h3>
  </div>

  <div class='movie'>
    <img src='/images/3.png'>
    <h3>Harry Potter and the Prisoner of Azkaban</h3>
  </div>

</div>

I hope this helps! Let me know if you have any questions about my implementation of this.

ANSWER

Answered 2020-Dec-31 at 02:33

It looks like you are 90% of the way there already.

All you need to do is replace your paragraph with a table that's organized how you want, then you need to update multiple table cells every time you click the button instead of just updating the one paragraph.

How you update the table cells depends on how the data is stored.

For example, if you had all the titles in one array and all the directors in another array and the years in a third array, you'd have to update one cell with titlesArray[randomNumber] and another cell with directorsArray[randomNumber] and another with yearsArray[randomNumber] — and you'd have to make sure the movies were in order in each array and nothing was missing anywhere.

However, if at all possible, the easier solution is to store each movie's data as an object. This is a perfect use case.

Your array of strings would simply become an array of objects. You would get a new random number for the index of the array, then you'd reference the properties of the object at that index for the particulars of that movie.

Simple example here that you can build on:

const movies = [
  {
    title: 'Star Wars Episode IV: A New Hope',
    director: 'George Lucas',
    year: '1977',
  },
  {
    title: 'Mission: Impossible III',
    director: 'J. J. Abrams',
    year: '2006',
  },
  {
    title: 'Spider-Man 2',
    director: 'Sam Raimi',
    year: '2004',
  }
];

const titleCell = document.getElementById('newMovieTitle');
const directorCell = document.getElementById('newMovieDirector');
const yearCell = document.getElementById('newMovieYear');

function getMovie() {
    const randomNumber = Math.floor(Math.random() * movies.length);
    const newMovie = movies[randomNumber];
    titleCell.textContent = newMovie.title;
    directorCell.textContent = newMovie.director;
    yearCell.textContent = newMovie.year;
}

<table>
  <thead>
    <tr>
      <th>Title</th>
      <th>Director</th>
      <th>Year</th>
    </tr>
  </thead>

JAVA - Difficulty scanning in a TXT file containign a mix of different information

Asked 2020-Dec-07 at 21:33

I have a text file containing a list of names and a list of books in this form:

5
Prisoner Azkaban
J. k. Rowling
Eragon
Christopher Paolini
Ulysses
James Joyce
Of mice and men
John Steinbeck
War and peace
Leo Tolstoy
4
Craig David
Isabel Campbell
Lee Rinaldo
Bethany Waters

The numbers tell you how many"objects" come after the number, starting with a cycle of book name > author, then this pattern stops repeating for the users section where user names are listed.

Here is my attempt at the code:

 Scanner inFile = new Scanner(new FileReader("C:\\Users\\finla\\IdeaProjects\\Untitled1\\src\\books2.txt"));
    
    int numberOfBooks = inFile.nextInt();


    for (int i= 0; i <= numberOfBooks; i++){
        String bookName =  inFile.nextLine();
        System.out.println("Book name: " + bookName);
        String bookAuthor = inFile.nextLine();
        System.out.println("Book author: " + bookAuthor);
    }
    int numberOfUsers = inFile.nextInt();
    for (int i= 0; i <= numberOfUsers; i++){
        String userName =  inFile.nextLine();
        System.out.println("User name: " + userName);

    }

Here is the output:

Book name:

Book name: J. k. Rowling
Book author: Eragon
Book name: Christopher Paolini

Book name: Leo Tolstoy
Book author: 4

The book author label i in the wrong place. The loop shouldn't print out the 4 at the end. I would like to be able to read in the list of people at the end. Do you have any suggestions as to why my code won't work? I've tried using next() as opposed to nextline(), but this doesn't solve the problem and only takes the first string from each line.

You want your for loops to go from 0 to < the count or else from 1 to the count as in:

for (int i= 0; i < numberOfBooks; i++){
}

You had <=, which means you consumed 1 line too many.

QUESTION

Is it possible to remove cascading CTEs in this query when trying to add ROW_NUMBER

Asked 2020-Oct-22 at 17:01

I have a reading list in a database. I use this as a base for personal training It has grown in functionality over time, so please forgive the odd structure.

I'm trying to add paging to this query but I'm having an issue trying to add the ROW_NUMBER method because of how I implemented "Ord" in my query.

I was able to get this working utilizing cascading Common Table Expressions but feel there must be a better way.

Here is what the output should do when displaying all books by an author:

Display completed books from oldest completed to newest
Then display the currently defined reading list controlled by the "Status" column
Then display any other books by that author not already listed

Setup

CREATE TABLE #books(
    ID int,
    Author nvarchar(100),
    Title nvarchar(100),
    Series nvarchar(100),
    BookNumber int,
    DateCompleted smalldatetime,
    [Status] int
)
INSERT INTO #books (ID, Author, Title, Series, BookNumber, DateCompleted, Status) VALUES 
(1004,'J. K. Rowling','Harry Potter and the Chamber of Secrets','Harry Potter',2,'1-Mar-2020',1),
(1045,'J. K. Rowling','Harry Potter and the Prisoner of Azkaban','Harry Potter',3,NULL,2),
(1047,'J. K. Rowling','Harry Potter and the Goblet of Fire','Harry Potter',4,NULL,3),
(1048,'J. K. Rowling','Harry Potter and the Order of the Pheonix','Harry Potter',5,NULL,4),
(1049,'J. K. Rowling','Harry Potter and the Half Blood Prince','Harry Potter',6,NULL,NULL),
(1051,'J. K. Rowling','Harry Potter and the Deathly Hallows','Harry Potter',7,NULL,NULL),
(1185,'J. K. Rowling','Harry Potter and the Sorcerer''s Stone','Harry Potter',1,'1-Jan2020',NULL)

DECLARE @Author nVarChar(100) = 'J. K. Rowling'
DECLARE @Year nVarChar(5) = ''
DECLARE @PageNum INT = 1;
DECLARE @PageSize INT = 10;

Original Query

SELECT b.ID,
       b.Title,
       b.Series,
       b.BookNumber,
       ISNULL(b.Series, '') + ISNULL(' (book ' + LTRIM(STR(b.BookNumber)) + ')','') as SeriesDesc,
       b.Author,
       Case
            When b.[Status] = 1 Then 'Completed'
            When b.[Status] = 2 Then 'Reading'
            When b.[Status] > 2 Then 'Next'
       End as StatusDesc,
       b.[Status],
       b.DateCompleted,
       CASE 
         WHEN b.DateCompleted is not NULL THEN 0
         WHEN b.[Status] is not NULL THEN 5
         WHEN b.[Status] is NULL THEN 9
       END as Ord
FROM #books b
WHERE (((b.Author = @Author OR @Author = '') AND b.DateCompleted is not NULL) AND
      (Year(b.DateCompleted) = @Year OR @Year = ''))
      OR
      (b.Author = @Author AND b.DateCompleted is NULL AND @Year = '')
ORDER BY Ord, [Status], DateCompleted, Series, BookNumber

This is the only way I've been able to get this to work as expected.

;WITH Step1 AS
(SELECT b.ID,
       b.Title,
       b.Series,
       b.BookNumber,
       ISNULL(b.Series, '') + ISNULL(' (book ' + LTRIM(STR(b.BookNumber)) + ')','') as SeriesDesc,
       b.Author,
       Case
            When b.[Status] = 1 Then 'Completed'
            When b.[Status] = 2 Then 'Reading'
            When b.[Status] > 2 Then 'Next'
       End as StatusDesc,

      (Year(b.DateCompleted) = @Year OR @Year = ''))
      OR

),
Step2 AS
(SELECT ID, Title, Series, BookNumber, SeriesDesc, Author, StatusDesc, [Status], DateCompleted, Ord,
ROW_NUMBER() OVER (ORDER BY Ord, [Status], DateCompleted, Series, BookNumber) as RowNum
FROM Step1)

SELECT
    ID, Title, Series, BookNumber, SeriesDesc, Author, StatusDesc, [Status], DateCompleted, Ord, RowNum
FROM Step2
WHERE @PageNum = 0 OR (RowNum BETWEEN (@PageNum - 1) * @PageSize + 1 
                       AND @PageNum * @PageSize)
ORDER BY RowNum

There is only 1 join for author_id = 2, and it's on series_id = "2-1":

insert into series_id VALUES (2, "2-1",  "Harry Potter", 8, 1997);
insert into series (series_id, name_book) VALUES("2-1", "Harry Potter and the Philosopher's Stone");

It looks like you are cramming multiple things into series_id, namely an actual series_id and a sequence within the series. I suggest you create separate columns for each concept.

See First Normal Form - Columns should contain only 1 value.
