kandi X-RAY | Bitter Summary
The Bitter library extends all the basic Swift Int types with some useful methods for manipulating bits. The objective of the library is to make the code dealing with bits and bitwise operations more concise and readable, through the use of shorthand methods where they make sense. With Bitter you'll be able for example, to replace this:.

QUESTION
I have a problem when I try to update or delete data from my MongoDB Atlas database.
The thing is, it looks like the "updateOne" and "deleteOne" methods are being called but not in the right way.
Whenever I try to retrieve the operation the result is the following:

QUESTION
I have a Django app that I would like to package and offer the community through Pipy. Its only strong dependance is Django. It also integrates nicely with Django CMS and offers additional integration for Django CMS. I plan to offer this additional functionality only to projects with Django CMS installed. (This is what I call a weak dependency - will install and work without it, but work even bitter with it.) Specifically, some models are only defined if the base model CMSPlugin
from Django CMS is installed.
Is there a good/right way to manage migrations, though?
I cannot include migrations of models depending on CMSPlugin
in the package since users w/o a Django CMS installations will not be able to run it.
If I omit the migrations depending on CMSPlugin
users with Django CMS will create them on first installation. I fear, however, that on every update of the package those migrations will be lost on pip install upgrade
when the package is overwritten.
ANSWER
Answered 2021-May-02 at 11:43Since these models are not necessarily used in your package it is best to have them in another Django app, which can be a sub-app of your app or perhaps just one of the apps present in your package. If a user has installed CMSPlugin
then they can now simply add this extra app of yours to the INSTALLED_APPS
list to use it, this also comes with the benefit that your users now have the choice to use it or not.
This way you can also easily adapt your views if this app is installed or not by using the app registries is_installed
method [Django docs]:
QUESTION
I'm creating a simple survey using jQuery where if user rates 3 stars or below, one div is opened. But if user rating is 4 or 5 stars, another div opens.
Everything works fine if you make a direct rating, for example, you select 3 stars and click "Submit".
However, if you select 3 stars, but then change your mind and select 4 stars, both div's are shown.
It's like the browser is remembering my last choice. Is there any way to reset behavior after initial selection?

QUESTION
following are my files for html, .ts and json . As json data was very extensive therefore i have just added a few states and their cities. my 1st dropdown is showing all states. Now I want to match my 1st dropdown's selected value of state with a key "state" in "cities" object in my json file so i can populate 2nd dropdown with cities relevant to that state. and I want to do this in function "getCitiesForSelectedState". please help me find solution for this.
//.ts file
...ANSWER
Answered 2021-Apr-27 at 16:44You can do it with the $event
parameter.
Make sure to compare your values safely.
If your value is not in the right type or has spaces or unwanted chars, this c.state == val
might not work.
You can use the trim
function to compare your value safely:
c.state.trim() == val.trim()

Edit 2: Updated to take care of the problems from the dput output.
I don't know why the dput output is not working, so here is a roundabout way of sharing the data.
A simple zip file of the data can be downloaded from here: link to zip file
The following code should then represent the data I was trying to share. Note that you will need to replace the path name for the downloaded zip file, and that the parse_file function will create a temporary directory:

QUESTION
The purpose of this program is to accept two numbers from the user, and figure out the two inputted numbers' factors and if they have any factors that are squares.
When I try to run it, it throws an error on the function call of conclusionaryOutput()
:
[cquery] address of function 'listSquares' will always evaluate to 'true' [-Wpointer-bool-conversion]
and:
...use of undeclared identifier 'isASquare1'; did you mean 'listSquares'?
ANSWER
Answered 2021-Mar-08 at 23:34When you call your conclusionaryOutput
function (at the end of squareInquiry
) you must give it the names of actual variables in the calling module rather than use the names of the parameters given in the function's definition. (This may be a basic misunderstanding of function calling in C++ because, everywhere else in your code, you appear to use the same names for local variables and formal parameters.)
So, rather than:

I'm populating an object from an O365 REST call, then filtering using multi-select dropdowns in a SPfx FluentUI Detailslist app. My code is appending the results from any of the values from each of the dropdowns versus narrowing down the results to meet all the filter conditions.

...ANSWER
Answered 2021-Mar-04 at 18:37The issue is that each for loop you have is independent of the predicate used to filter out objects. To fix this you need to bring the predicates all into the same scope so that things that should be omitted do not get added in due to the scope of the current predicate. For example:
