Pony is an advanced object-relational mapper. The most interesting feature of Pony is its ability to write queries to the database using Python generator expressions and lambdas. Pony analyzes the abstract syntax tree of the expression and translates it into a SQL query.

QUESTION
I am having trouble bounding my ListView in QML.
I have taken the example provided by Qt (slightly modified but the exact code from the Qt example has the same issue), and tried to integrate it into my window.
As you can see in the image below, the ListView is supposed to be the size on the white Rectangle in the middle, yet the section headers are always visible, and the list elements are visible until completely out of the container Rectangle ("Guinea Pig" and "Tiger" are completely visible, although one would expect them to be only half visible)
I am sure the error is trivial, but i have tried all sorts of anchors and container types, but can't resolve this issue.
Here is the code :
...ANSWER
Answered 2022-Mar-04 at 18:37You are simply missing the clip property. That tells the object to prevent child objects from drawing outside of its borders. clip is set to false by default because most of the time its not needed and has a little bit of a performance hit.
QUESTION
I'm using g-s-i a npm package to make calls to google images.
I'm unable to make this API call and, just after, render the application. I'm aware this has to do with async, but I have no idea how to use it here. I have tried many things with the function imageSearch, but nothing has worked.
I thank if someone can show me a solution to my problem.
My MWE:
HTML:
...ANSWER
Answered 2022-Jan-14 at 17:33Your imageSearch function calls gis() which doesn't successfully create the response object until the callback passed as the second parameter to gis() is called. However, you're immediately returning the empty response array.
Instead, pass a callback in to imageSearch that gets called when gis() returns, something like this:

I tried to cluster my dataset using K-mean, but there is a categorical data in column 9; so when I ran k-mean it had an error like this:
...ANSWER
Answered 2021-Dec-17 at 17:31To solve your specific issue, you can generate dummy variables to run your desired clustering.
One way to do it is using the dummy_columns() function from the fastDummies package.
QUESTION
I ran multiple imputation to impute missing data for 2 variables of a data frame, then I got a new data frame (with 2 columns for 2 imputed variables).
Now, I want to replace the 2 columns in the original data frame with the two newly imputed columns from my new dataframe. What should I do?
Original data frame new data frame for imputed variables
This is the code I used. Only 2 columns in this data frame are missing data, so I only imputed those two. Is that ok? Can you please suggest me a better way?
...ANSWER
Answered 2021-Dec-14 at 22:53Updated
As @dcarlson recommended, you can run mice on the entire dataframe, then you can use complete to get the whole output dataframe. Then, you can join the new data with your original dataframe.
QUESTION
Eventually, when I am in a debug session, the current file is named "". What I would expect to see is the name of the module where the debugger is currently on.
The same happens on the traceback:
...ANSWER
Answered 2021-Nov-12 at 14:11It means that the code came from something that was not a file, but a string. My guess would be an exec() call, but maybe there are other ways of getting the same effect. The previous stack frame might give some clues.

Answered 2021-Oct-28 at 20:03The Entity.to_dict function has a related_objects keyword argument.
You can use it to include the objects in the dicts.
If you want the to-many relationships too, you also need the with_collections argument.
QUESTION
I have a working function which is around 250 lines, a simplified version:
...ANSWER
Answered 2021-Oct-28 at 12:59This entire concept is flawed. R is a (largely) functional programming language, and users don't expect side effects, particularly (over)writing objects in the calling environment. A far better idea is to have your function return a list of data frames.
Lists are better than directly writing to the calling environment for a number of reasons. They avoid cluttering the global workspace, they can be iterated over, their elements can be named or unnamed, they can be nested, they can be converted into environments, and they can act as a container to allow a function to return multiple objects - just as in your example.
The standard R way to use a function like yours would be something like this:

Below is a minimal example of my code.
I have a grouped pd.Series with Multiindices and can access single elements using grouped["stallion", "london"], but when using grouped.get(["stallion", "london"]) the result is None (or -1 when a default value is given).
ANSWER
Answered 2021-Oct-19 at 15:14You have to use tuple to get values because your index contains tuples (this is not a MultiIndex)
QUESTION
(forgive me for spamming, I should have adjusted the original question, but it felt like I ran into a new hurdle when solving the problem)
I set a goal of running a web server with ansible: figured I'd sit it inside a tmux session. I quickly ran into ansible play hanging forever due to tmux dropping into it's own shell, but with community's help got halfway to the goal. I can run my server, but there's no tmux session to be found on the box.
the playbook's task is this:
...ANSWER
Answered 2021-Aug-25 at 17:03Not really an answer, but fleshing out some background as to how tmux works.
When you run tmux, it tries to connect to (or create if necessary) a server running on a particular Unix socket. By default, the path to that socket is something like /tmp/tmux-$USERID/default. You can change the directory using the -L option or the TMUX_TMPDIR environment variable. You can ignore both those using -S to specify an exact path your self.
For example,

Install pony
You can use pony like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
