I got a Django project and its model, this module imported:
from push_notifications.models import BareDevice
I have installed push_notification library successfully but the problem is, this library don't have any function or class named BareDevice
Can anyone know about this? I just stuck with this project only for this BareDevice

to sum up my circumstances:
I am running everything locally
I am using flask in the backend within a virtual environment
Goal: build a socket connection between Flask Backend and JS Frontend
PROBLEM: the problem is in the Frontend which is based on JS where I can't import the modules I got with npm
I am importing the modules as follows:
import { io } from "socket.io-client"
import { Hands } from "/#mediapipe/hands"
I also tried different import variants such as import * as io from "socket.io-client" and I also tried importing directly files as follows: import {io} from "socket.io-client/dist/socket.io", but all without success as these lead to "not found" errors.
I am sure that I installed them correctly with npm as I can see them in the folder structure, but the es6 imports are throwing an error as follows:
Failed to resolve module specifier "socket.io-client". Relative references must start with either "/", "./", or "../" - To solve this I tried adding slashes to different places like in the html tag where I include the script I tried transforming "type="module"" to "type="/module"" as recommended somewhere online, but without success. Also building direct references in the imports like "./node_modules/socket.io-client" do not work as it states that the file/folder is not found.
The problem must be the usage of the imports as everything works when I use Content Delivery Networks which also lets me assume that the version of the packages is not the problem as the version I get from the CDN is the same, but still the versions I use:
socket.io-client: 4.6.0
#mediapipe/hands: 0.4.1675469240
Flask: 2.2.3
Flask-SocketIO: 5.3.2
npm: 8.19.3
node: 16.19.1
My folder structure is as follows:
venv
main.py
templates
index.html
static
node_modules (includes socket.io-client and #mediapipe/hands)
js
main.js (the js file where the problem occurs)
package.json
I read a few times that the usage of "Webpack" is recommended, but I would like to skip that currently as I am not very familiar with that, so one question would also be: is it necessary to use it?
What can I possibly do wrong or how can I track my problem when it is about the import of es6 modules?
I would appreciate any help. Thanks in advance!
I could solve my problem for the socket.io-client package:
For the socket.io-client I imported a specific file directly although I do not really know why it worked as follows:
import { io } from './node_modules/socket.io-client/dist/socket.io.esm.min.js'
For the mediapipe package I still could not import the module in my js file directly and I am still relying on CDN. I tried the same thing in the same way by using:
import * as Hands from './node_modules/#mediapipe/hands/hands.js'
This, at least, does not result in an error, but the usage of "Hands" in this case is unclear to me as there is also no documentation for this use case in the mediapipe-js documentation. I could not directly import the {Hands} function as it resulted in an error saying "there is no function Hands in that path"
I am developing multiple websites in angular with similar content and have therefore decided to extract common components and functionality into a separate angular 14 library.
I have previously successfully used the JSZip library in one of these websites with Angular 12, but have then decided to move this implementation into the library.
Even though the code did not change, it stopped working.
If I try to call the method that uses JSZip from the library it now throws the following TypeError
ERROR TypeError: (jszip__WEBPACK_IMPORTED_MODULE_1___namespace_cache || jszip__WEBPACK_IMPORTED_MODULE_1___namespace_cache) is not a constructor
Import library like this
import * as JSZip from 'jszip';
create a new JSZip instance like this
const zip = new JSZip();
Both the library and the website projects build correctly but throw this error at runtime, so I don't think it is a problem with dependencies.
Has someone encountered a similar problem before? What should I try to solve this?

I saw similar post like this
I'm currently building a minimalist app following this CMake architecture:
-root
--QmlModule
---Component1.qml
---Component2.qml
--App1
---main.cpp
---main.qml
--App2
---main.cpp
---main.qml
I use "qt6_add_qml_module" to create a QML module at "QmlModule" level as a STATIC library.
qt_add_library(myComponentTarget STATIC)
qt6_add_qml_module(myComponentTarget
URI QmlModule
VERSION 1.0
QML_FILES
Component1.qml
Component2.qml
RESOURCES
logo.png)
Then, at App1 (and App2) level, a link to the module is done using "target_link_libraries". "qt6_add_qml_module" does some work behind the scenes in order to expose the module trough an automatically generated plugin named "your_component_URIplugin". More details about this here.
add_executable(App1Exe
main.cpp)
qt6_add_qml_module(App1Exe
URI App1
VERSION 1.0
QML_FILES
main.qml)
target_link_libraries(App1Exe
PRIVATE
myComponentURIplugin)
At Root level, I overload QML_IMPORT_PATH in order to link to the build folder and add all subdirectories.
set(QML_IMPORT_PATH ${CMAKE_CURRENT_SOURCE_DIR}/qmlModule)
add_subdirectory(QmlModule)
add_subdirectory(App1)
add_subdirectory(App2)
I run CMake without any errors, and open App1/main.qml file.
On my import QmlModule, the module can't be found:
module "lupinComponentsplugin" is not installed
How to make my module visible from my Apps ?
What step am I missing ?
I'm currently doing something similar.
I have created a demo app where I import modules. The modules provide QML and C++ items to the main app. Check the comments in the CMAKE files to find out how this works.
Here is the link:
https://gitlab.com/basic53/DemoApp
Feel free to comment on this.
Another tip: If qt_add_qml_module is not working properly, sometimes it is necessary to remove the whole build folder and update the QML code model. You can check the generated files to see, if your plugin has been created with all its types.
CMake itself was fine, this was a runtime error and not a link error.
This issue was raised because the QQmlApplicationEngine wasn't finding path towards my module's QMLDIR.
In the end, the only thing missing was an additional import path ":/" in QQmlEngine:
QQmlApplicationEngine engine;
engine.addImportPath(":/");
I'm trying to add django-messages to my app but I'm getting this error when I add it to my installed apps
ImportError: cannot import name 'python_2_unicode_compatible' from 'django.utils.encoding' (C:\Users\Acer\AppData\Local\Programs\Python\Python38-32\lib\site-packages\django\utils\encoding.py)
I've looked up this error and apparently it's caused by this line in Django-Messages models.py
from django.utils.encoding import python_2_unicode_compatible
To fix it I should change it to
from django.utils.six import python_2_unicode_compatible
As this is a third party app, how should I change this line?
Should I copy the file structure into my own project (creating a django-messages folder among my apps then a models.py file inside it) and copy/paste the entire models.py into there and then change the line? This seems wrong, but I don't know how else to fix it.
Or does the fact that it's using an outdated import signify that the app isn't maintained and therefore shouldn't be used at all?
Thank you.
I can suggest two options. First, you can clone it on GitHub (i.e. download all the files) and then paste this into your project folder (along with your other apps). And then you can make any changes you wish. Of course it remains to be seen whether it will work then, as there might be other issues. It seems to be compatible with Django 1.11 - 2.2. But I would think that it's a better option than doing this all yourself. Unless you can find a different app that suits your needs.
Second, assuming you are using a virtual environment, you can navigate to where all your packages are installed. I'm not sure where this will be located for you, but it should be something like envs\<name of env>\Lib\site-packages. And there you can make any changes you wish - just search for the relevant file.
Hope this helps.
I have to write automation scripts using python and Robot framework. I have installed python, Robotframework, RIDE, wxpython. I have installed sikuli library but when I import it in my project, library is not imported. I have tried 'Import Library Spec XML'. My question is from where do I import this .xml or how do I create it?
You might need to declare the Pythonpath on RIDE preferences (Tools>Preferences>Importing), you must add there your libraries location, it helped me with suds library.
I have added there:
C:\Python27\lib\site-packages\robot\libraries
(This could be little different for you if you have installed your python at different location)
Edit:
This could be an issue on the way you are trying to import your library, or you need to download a specific sikuli library that work with robot.
Please check then if you are loading your library like this:
*** Settings ***
Library SikuliLibrary
got it from: https://github.com/rainmanwy/robotframework-SikuliLibrary
First check whether Sikuli is installed in python directory's \Lib\site-packages.
Robot test should contain as below:
* Settings *
Documentation Sikuli Library Demo
Library SikuliLibrary mode=NEW
* Test Cases *
Sample_Sikuli_Test
blabh blabh etc
