jacks | Jackson module for Scala | JSON Processing library

I'm a student coder. I would like to create a list of buttons. However there are too many buttons to fit onto a single screen. I have tried to incorporate a scrollbar, however the buttons do not go inside the textbox, even after setting the window to 'text'.

Here's what ive tried:

I've been at this problem for so long that I'm not even sure where I am with it. I've written the following management command which generates some JSON and saves it using a Django model. Later I have a view which retrieves this JSON and displays it in a URL.

The model is as follows:

I have a JS object array as :

In CoreData each instance of NSManagedObject is unique. This is why CoreData uses NSSet (and its ordered counterpart NSOrderedSet) to represent collections. However, I need a list that permits an item to appear more than once.

My intuition was to wrap each object in a ListItem entity, and use NSOrderedSet to generate the list. Since the list items themselves are unique, the objects can appear as many times as needed in the list. However this produces unexpected results.

In this example app, iFitnessRoutine, the user can select from a list of activities such as jumping jacks, sit-ups, and lunges. They can then construct a FitnessCircuit to create a list of activities and perform each for a certain duration. For example:

Morning Circuit:

1. Jumping Jacks: 60 seconds
2. Lunges: 60 seconds
3. Sit-ups: 60 seconds
4. Jumping Jacks: 60 seconds
5. Sit-ups: 60 seconds
6. Jumping Jacks: 60 seconds

In my implementation, each Activity is wrapped in a ListItem, however the result produces something like this:

Morning Circuit:

1. ListItem -> Jumping Jacks: 60 seconds
2. ListItem -> nil
3. ListItem -> Lunges: 60 seconds
4. ListItem -> Sit-ups: 60 seconds
5. ListItem -> nil
6. ListItem -> nil

I can add multiple list items, but duplicate activities are not being set.

My data model looks like this, with the listItems relationship defined as an NSOrderedSet. For CodeGen, I use class definition to have Core Data automatically generate the NSManagedObject subclasses.

I set up my Core Data stack as usual, and populate it with seed data if necessary.

I am trying to troubleshoot my data, and check whether a certain name appears in two different columns in the same row (same observation):

I want to join 2 tables and search value with like (only first 4 strings will be compared) in join. But the result should be only 1:1, I want to prevent multiple results for 1 entry in the main table.

tab1

tab2

Result

I get more than one result for each entry in tab1.

So I've got a string being sent to a class that is split by \n for format. I was wondering if it was possible to underline specific words of the string so it looks better?

Currently this is what is being passed

I am learning data mining from a book and I am trying to write my first script to gather info from Youtube's API and feed it into a new .csv file. For some reason, it isn't working. I tried inputting the script line by line in a CLI and the script will eventually create an empty .csv file, but the information is never fed in. Here is my code, it's basically copied line by line from the book:

My goal is to match address information based on 2 separate data frames. One data frame contains a unique value and the other dataframe does not. Id like to take the unique key from df1 and copy it to df2 based on how similar the fuzzy match is.

Here's an example:
