I'm trying to run a .py file and in the file I have this import
from config.wsgi import *
import os
from django.template.loader import get_template
from weasyprint import HTML, CSS
from config import settings
The whole project works, if I set runserver, the project starts without any problem, but this file does not work. The structure of the project is as follows
NombreDelProyecto
--app
---config
----__init__.py
----asgi.py
----settings.py
----wsgy.py
----db.py
---core
----general
----login
----user
----archivodetest.py
the case as I say the project works, but in the views of the applications that I have been doing to put imports I get in red underlined but as I say it works for example:
from core.general.forms import ActividadForm
That comes out in red, if I put in front of the core, app.core as follows
from app.core.general.forms import ActividadForm
it does not show red but the project does not work and I get the following error
from app.core.general.forms import ActividadForm
ModuleNotFoundError: No module named 'app'
I understand that it is the routes or something I did wrong from the beginning, please could someone help me.
Thank you very much.
I tried adding the route, changing the app's route in settings, but to no avail.
You've named the file wsgy.py but it needs to be wsgi.py.
Rename your file in config and retry.
To your question, I think its because you're missing the __init__.py file in the general app.
If you haven't already go one, you'll likely need to have add the same again in your core app too.
You probably manually created all of these files and structures I suspect, and if that's the case, please take a look at the documentation regarding creating new apps inside a django project.
If you go a bit further up the page, it will also tell you how to create the initial django project structure with a command.
Thank you very much for the answer, I managed to solve it after a lot of testing.
There are two ways, open the project again from the app folder (I had it open in the ProjectName folder).
Or as a second option in pyCharm on the left where the project folders are, I went to the app folder (which is the root) and right clicked and in the menu, Mark Directorie as - Sources root. Then my problem is fixed.
I had all the arcvhiso init.py, and where I put the wrong name wsgi.py is that I wrote it wrong here but in the project it was right.
Thank you very much for the help.

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 am testing Google Cloud and first I wanted to develop something on my PC before I use in on google cloud.
I am using APACHE and configured it in that way, that when I am going to the page localhost/wsgi_app I see my page which physically is stored in folder /svc/http/webapp2. File wsgi_app.py which contains my app is stored in subfolder webapp2. All works fine. I provide this information just in case it might play any role.
The issue I have is with import from library.
I did it on Django and now try to move it to webapp2.
The first lines of my program look like this:
import webapp2
import MySQLdb
import json
I have file called test.py which contains some classess and funtions.
it is in the same folder as wsgi_app.py.
I want to include it, however this seems not to work:
import webapp2
import MySQLdb
import json
from test import *
my test.py contains definition of the class 'Quote', but when I call the page I see error
NameError: global name 'Quote' is not defined
When I put the inside of the file test.py in the file wsgi_app.py all works fine.
My goal is to separate the code into several files.
Any idea why :
from test import *
does not work ?
It worked on any other program I wrote, so why not here?
issue solved.
issue is not related to weapp2 but to WSGI and the path where python search for files.
Most simple solution is to add something like this ;
execfile("/srv/http/test.py")
it will import the file.
other than this here is quite good article

I'm having a weird problem with import views in Django project. I'm not sure whether it is a problem caused by PyCharm of Django. So PyCharm says that it can't import views.py file, but it works when I run the server.
Here is the picture:
Do you know where could be the problem?
EDIT:
According to Inlangers answer, I've tried to change import to from vlado_web.translations import views which did not helped, moreover, it raises
Exception Value:
No module named translations
When I have from translations import views there, it works correctly but PyCharm says that it can't be resolved.
PyCharm doesn't know where your source files are. Try this:
Right click on folder vlado_web (the folder that contains manage.py) within PyCharm. Go to Mark Directory As and choose Sources Root.
This will let PyCharm know that the vlado_web directory is the root folder for your source code, and will allow you to perform absolute imports from there, e.g.
from vlado_web.translations import views
Try from vlado_web.translations import views
I'm trying to deploy a django app to heroku.
I have several python libraries which are not on PyPi and so I can't just declare them in requirements.txt file
In local development I've used:
import sys
sys.path += [os.path.dirname(os.path.dirname(__file__))+"\\project-name\\lib"]
inside manage.py and it works fine there.
Obviously it doesn't work on heroku and I get import errors.
What is the recommended way to add libraries like that on heroku?
Thanks.
One way to do it is include the libraries in the repository itself, from which you can import them. That means simply moving the actual folder for each library into your main Django project folder.
- DjangoProject
- AppFolder1
- AppFolder2 ...
- python-library1
- python-library2
When the repository is pushed to Heroku your libraries will be pushed as part of the project.
From here, your imports of these libraries within a view/model etc within any app's folder would
import python-library1
from python-library2 import a_function, a_class
The reason why I suggest the directory structure above is that, most likely, you would not have go back and change any import codes.
If you have a large number of libraries and would like to keep the direcory structure simpler, simply create a folder with a name such as "importables" in the main DjangoProject folder and change the import statements to something such as...
from importables import python-library1
from importables.python-library2 import a_function, a_class
It's not exactly beautiful, but a quick way to get the job done. If you aren't sure where the libraries you'd like to include are located, there's a few ways to quickly see their location using Python (How do I find the location of Python module sources?).
I know this question has already been asked multiple times but I still can't seem to find a solution that works for me. My Django project folder looks like this:
my_project
__init__.py
manage.py
my_first_app
my_second_app
core
Now the "core" folder looks like this:
__init__.py
some_other_stuff.py
settings
__init__.py
prod.py
dev.py
local.py -> dev.py
local.py is a symbolic link pointing to the right settings file, dev.py on my machine, prod.py in production.
Here's my problem: when I try to use manage.py, I get a weird error ImproperlyConfigured: The SECRET_KEY setting must not be empty. When I pass the path to the settings file local.py as an argument (--settings=core.settings.local) it runs fine. I figured the problem was that Django didn't know where to look for the settings file. How can I tell him (her?) where to look?
I already tried exporting the path to the env (export DJANGO_SETTINGS_MODULE=core.settings.local) and setting the PYTHONPATH to the parent directory, to no avail.
The primary use of __init__.py is to initialize Python packages. The easiest way to demonstrate this is to take a look at the structure of a standard Python module.
package/
__init__.py
file1.py
file2.py
As you can see in the structure above the inclusion of the __init__.py file in a directory indicates to the Python interpreter that the directory should be treated like a Python package
__init__.py can be an empty file but it is often used to perform setup needed for the package(import things, load things into path, etc).
One common thing to do in your __init__.py is to import selected Classes, functions, etc into the package level so they can be convieniently imported from the package.
In our example above we can say that file.py has the Class File. So without anything in our __init__.py you would import with this syntax:
from package.file import File
However you can import File into your __init__.py to make it available at the package level:
# in your __init__.py
from file1 import File
# now import File from package
from package import File
Source
So for conclusion, when you call import in __init__.py in a package mypackage, it's like you use package as a simple python file, that's what my solution do:
from .local import * in __init__.py
I haven't use this before in the settings case but I use it when I wanna to subdivide my models in a Django app, models.py --> models package, ./manage syndb doesn't discover my models declared, I found so this solution that's similar. You can find more details here
Last thing, I'm sure there's others solution to your problem, but this can be the most simple.
Good luck
You are in import hell somewhere. Had this problem too one time. The only way to find out where the root of your problem is, might be to disable all apps, try starting the server, enable the first app, start the server, enable the next etc.
BTW: your project layout should not be used from Django 1.4 onward. https://docs.djangoproject.com/en/dev/releases/1.4/#updated-default-project-layout-and-manage-py
I'd try to use the new layout and hope that it 'just works'.
I think you need to change the name of the file that the manage.py is looking for.
try:
imp.find_module('settings') # Assumed to be in the same directory.
except ImportError:
import sys
sys.stderr.write("Error: Can't find the file 'settings.py' in the directory containing %r. It appears you've customized things.\nYou'll have to run django-admin.py, passing it your settings module.\n" % __file__)
sys.exit(1)
If you had the settings.py file in the same directory simple changing the 'settings' to 'local' would have worked.
But, since you have it in a different directory, I think you need to configure the settings. Refer to this: https://docs.djangoproject.com/en/dev/topics/settings/#using-settings-without-setting-django-settings-module
from django.conf import settings
settings.configure(DEBUG=True, TEMPLATE_DEBUG=True,
TEMPLATE_DIRS=('/home/web-apps/myapp', '/home/web-apps/base'))
Hope that helps.
