Heroku gettext installation - django

I want to install gettext in Heroku. I have added: https://github.com/lexifdev/heroku-buildpack-gettext.git into the buildpacks section of my app. However, when I run
heroku run python manage.py compilemessages -l en
I get the error message: CommandError: Can't find msgfmt. Make sure you have GNU gettext tools 0.15 or newer installed.

Had the same problem my friend. Here's how I fixed it:
From the heroku dashboard, add the following buildpack: https://github.com/grauwoelfchen/heroku-buildpack-gettext.git
On your next deployment to heroku (e.g. a git push), it and any other buildpacks you have will be built and installed and all should work.

Here is how I did it
type the following commands
heroku buildpacks: add https://github.com/grauwoelfchen/heroku-buildpack-gettext
git push heroku master
Now, the gettext will be added

Heroku app crashes after pushing change with new dependencies

So I have a Django web app running on Heroku. I recently pushed an update where I added some API functionality via the Django Rest Framework. I installed this via pip. Now my Heroku app crashes. I assume I somehow need to install this dependency on Heroku? Here is the error message:
An error occurred in the application and your page could not be served. If you are the application owner, check your logs for details. You can do this from the Heroku CLI with the command
heroku logs --tail
I tried entering the Heroku CLI and typing pip install djangorestframework but and running Heroku restart but it still crashes.
Edit: some more details, I tried installing this dependency on my machine via git clone in addition to pip. When I pushed this code to Heroku, in the command line I see cannot stat '/tmp/build_5917e4123a7c/requirements.txt': No such file or directory
Edit2: Just to keep this post updated, I'm not trying to add a requirements.txt file to my project with this dependency in it. The file is in the root directory and the only text in it is:
djangorestframework==3.11.0
Edit3: I fixed it. See my answer
So I installed my dependency with pip install djangorestframework but I needed to use pipenv install djangorestframework. The Pipfile therefore never had this dependency added so Heroku wasn't able to see it since it seems Heroku checks the Pipfile. I guess requirements.txt is the old deprecated way to do this?

Install poppler onto Heroku Server django

I am trying to install poppler on my Heroku server because I am using pdf2image as a python package. However, I can't just run brew install poppler like I did on my Mac.
I have tried to add some heroku buildpacks off the internet but with no luck. Anytime pdf2image runs I get this error.
pdf2image.exceptions.PDFInfoNotInstalledError: Unable to get page count. Is poppler installed and in PATH?
Is there something I can do on the command line to get poppler installed while keeping heroku/python as my buildpack?
You can install APT packages with an experimental function on Heroku
Steps:
Add the buildpack to Heroku.
heroku buildpacks:add --index 1 heroku-community/apt
Make a file named Aptfile in your project folder and write poppler-utils inside.
Commit and push.
Is there something I can do on the command line to get poppler installed while keeping heroku/python as my buildpack?
Heroku lets you run multiple buildpacks. I haven't tried this buildpack, but I'd recommend adding this buildpack to your existing app:
heroku buildpacks:set heroku/python
heroku buildpacks:add --index 1 https://github.com/survantjames/heroku-buildpack-poppler.git
Then redeploy your application.

How to deploy Django on IIS with git hooks using virtenv on a remote Windows server?

I successfully installed and setup Django (2.0.2) using Python 3.6.4 on IIS on a remote Windows Server 2012 R2 (in a VPN environment) accordingly to this instruction:
http://blog.mattwoodward.com/2016/07/running-django-application-on-windows.html
I'm using SQL Server as backend and I stored the sensitive data such as the DJANGO_SECRET_KEY, DATABASE_PASSWORD etc. as environment variables in the FastCGI Settings at the IIS (see the above link, section Configure FastCGI in IIS step 14)
At this point I asked me, how to deploy my apps and do all the necessary setps like install packages from requirements.txt, collectstatic, makemigrations etc.
With googleing I found a possible solution using git hooks, especially a post-receive hook accordingly to this post:
https://dylanwooters.wordpress.com/2015/02/21/one-command-deployments-to-iis-using-git/
So I successfully setup Bonobo Git Server on the same IIS accordingly to this instruction:
https://bonobogitserver.com/install/
My thought was to put all the required commands into this post-receive hook file as I would do in the development environment. I ended up with this file at location \inetpub\wwwroot\Bonobo.Git.Server\App_Data\Repositories\myapp-master\hooks\post-receive:
#!/bin/sh
DEPLOYDIR=/c/apps/myapp
VIRTENVDIR=/c/virtualenvs/myapp
GIT_WORK_TREE="$DEPLOYDIR" git checkout -f
cd $VIRTENVDIR
source Scripts/activate
cd $DEPLOYDIR
pip install -r requirements.txt
python manage.py collectstatic --noinput
python manage.py makemigrations
python manage.py migrate
I grant permission to the Scripts/activate file and I receive no erros during push from my development environment. But the current problem is that the command at line 6 doesn't activate the virtual environment and therefore no migrations etc. happens. Normally I would activate the virtual environment with the command line prompt using these commands:
cd C:\virtualenvs\myapp
Scripts\activate.bat
but I can't use this in the post-reveive file because it uses unix-based commands.
Can anyone help me or have a better idea how to deploy in a nicer way in a windows environment without going into the cloud?

ImportError: Couldn't import Django

I've already configured virtualenv in pycharm, when using the python manage.py command, this is error shown:
E:\video course\Python\code\web_worker\MxOnline>python manage.py runserver
Traceback (most recent call last):
File "manage.py", line 17, in <module>
"Couldn't import Django. Are you sure it's installed and "
ImportError: Couldn't import Django. Are you sure it's installed and available on your PYTHONPATH environment variable? Did you forget to activate a virtual environment?
How should I fix it, I've installed django.
I think the best way to use django is with virtualenv it's safe and you can install many apps in virtualenv which does not affect any outer space of the system
vitualenv uses the default version of python which is same as in your system
to install virtualenv
sudo pip install virtualenv
or for python3
sudo pip3 install virtualenv
and then in your dir
mkdir ~/newproject
cd ~/newproject
Now, create a virtual environment within the project directory by typing
virtualenv newenv
To install packages into the isolated environment, you must activate it by typing:
source newenv/bin/activate
now install here with
pip install django
You can verify the installation by typing:
django-admin --version
To leave your virtual environment, you need to issue the deactivate command from anywhere on the system:
deactivate
When you install Django on your computer all things go fine but when you install a Virtual environment it gets separated from all things. You will know it's importance when you will make a final project and deploy it to any cloud or hosting.
Just reinstall Django in the virtual environment and baam:
pip install Django
and then just run the command for testing:
python manage.py runsever
and you are all done.
You need to install Django, this error is giving because django is not installed.
pip install django
You need to use both commands:
pip install django and pip3 install django
that worked for me
Check that you have installed Django; by executing import django in python.
you mustn't see ModuleNotFoundError if everything's ok.
Check that you have installed virtualenv; by executing virtualenv --version.
you must see the version number if everything's ok.
Check that you have enabled virtualenv; there's got to be the name of your virtualenv in your command prompt starting line. enable it by
source bin/activate. also, remember to deactivate it every time your job is
finished with the virtualenv.
Check that your virtualenv includes django. a virtualenv by default
has no modules installed. you either have to install django in your
virtualenv (even if you have it in your machine already) or use
virtualenv --system-site-packages when creating a virtualenv to
include system site packages in the virtualenv.
Add django to your path. open python, import django, then run
django to see django's path. then add it to your ~/.bashrc (or
~/.zshrc if you're using zsh). more info in here
Install django-admin by running pip install django-admin
find your django parent dir path and add it to PYTHONPATH
In my case, my django parent dir path is /Library/Python/3.7/site-packages,add this line into ~/.bash_profile
export PYTHONPATH=/Library/Python/3.7/site-packages
else if you have PYTHONPATH already, just append it like this
export PYTHONPATH=${PYTHONPATH}:/Library/Python/3.7/site-packages
then
source ~/.bash_profile
I was having great difficulties with this but I have solved my issue. I am on Windows 10 using Vagrant ssh in my virtualenv environment, the box I have installed is ubuntu/xenial64, Django version 2.1, python==3.6.
When I was installing packages I was using pip3 but most importantly I was using sudo and the -H flag to install these packages. When I ran sudo pip3 freeze my packages would come up, but when I ran a plain pip3 freeze there would be no packages.
Then I tried the python3 manage.py startapp <YOUR APP NAME> and it did not work same error as you.
I finally thought to try sudo python3 manage.py startapp <YOUR APP NAME> it finally worked!
Hope this was help :)
I faced the same issue, and in my case it was because I had multiple python versions on my machine, in addition to the Anaconda ones.
In my case django didn't worked well with my anaconda python.
I knew that when I run import django on each python terminal for all versions I have.
As a summary here are the steps I made to get this solved:
Run the CMD as Admin
Create a project folder.
Create a new ENV for this new project INSIDE THE PROJECT Folder...
pip install virtualenv >> virtualenv new_env`
Activate it:
.\new_env\Scripts\activate`
After the env activation ⇒ Install Django:
python -m pip install Django
The python version you used here in step 5 will determine which python will to work with this installed Django.
If you are working on a machine where it doesn't have permissions to all the files and moreover you have two versions such as default 2.7 & latest 3.6 then while running the command use the python version with the command. If the latest python is installed with sudo then run the command with sudo.
exp:
sudo python3.6 manage.py runserver
after activating virtual env that error raises up on ubuntu.
and I solve this issue just by typing again :
pip3 install Django
inside the directory which is I want to create a new app.
You can use python3 to run file, if you don't want to use virtualenv.python3 manage.py runserver
To install python3 look at this page
Make sure you have Django installed by writing this command :
python -m django --version
if it's not installed you can install it by writing this command :
pip install django
I solved this problem in a completely different way.
Package installer = Conda (Miniconda)
List of available envs = base, djenv(Django environment created for keeping project related modules).
When I was using the command line to activate the djenv using conda activate djenv, the base environment was already activated. I did not notice that and when djenv was activated, (djenv) was being displayed at the beginning of the prompt on the command line. When i tired executing , python manage.py migrate, this happened.
ImportError: Couldn't import Django. Are you sure it's installed and available on your PYTHONPATH environment variable? Did you forget to activate a virtual environment?
I deactivated the current environment, i.e conda deactivate. This deactivated djenv. Then, i deactivated the base environment.
After that, I again activated djenv. And the command worked like a charm!!
If someone is facing a similar issue, I hope you should consider trying this as well. Maybe it helps.
Instead of creating a new virtual environment, you just have to access to your initially created virtual environment when you started the project.
You just have to do the following in your command line:
1)pipenv shell to access the backend virtual environment that you have initially created.
2) Then, python manage.py runserver
Let me know if it works for you or not.
To create a virtual environment for your project, open a new command prompt, navigate to the folder where you want to create your project and then enter the following:
py -m venv project-name
This will create a folder called ‘project-name’ if it does not already exist and setup the virtual environment. To activate the environment, run:
project-name\Scripts\activate.bat**
The virtual environment will be activated and you’ll see “(project-name)” next to the command prompt to designate that. Each time you start a new command prompt, you’ll need to activate the environment again.
Install Django
Django can be installed easily using pip within your virtual environment.
In the command prompt, ensure your virtual environment is active, and execute the following command:
py -m pip install Django
In case you have virtual env activated, django installed, django-admin --version prints the valid version - check if there is no circular import in the file you are executing.
I faced the same problem when I was doing it on windows 10. The problem could be that the path is not defined for manage.py in the environment variables. I did the following steps and it worked out for me!
Go to Start menu and search for manage.py.
Right click on it and select "copy full path".
Go to your "My Computer" or "This PC".
Right click and select "Properties".
Select Advanced settings.
Select "Environment Variables."
In the lower window, find "Path", click on it and click edit.
Finally, click on "Add New".
Paste the copied path with CTRL-V.
Click OK and then restart you CMD with Administrator privileges.
I really hope it works!
Looks like you have not activated your virtualenv when using the runserver command.
Windows: <virtualenv dir>\Scripts\activate.bat
Linux: source <virtualenv dir>\bin\activate
You should see (name of virtualenv) as a prefix to your current directory:
(virtualenv) E:\video course\Python\code\web_worker\MxOnline>python manage.py runserver
windows :
(virtualenv dir)\Scripts\activate # this step to activate virtualenv
you should be in the dir of (project name)
python manage.py runserver
you need to go to the root directory
and run the below command
source bin/activate
Once the above command is executed, you will be able to create custom apps
I also face the same problem in windows 10 with anaconda
For me anaconda3\Scripts>activate
it's working good. What you have to do you just need to go to anaconda home
AppData\Local\Continuum\anaconda3\Scripts
and you need to open a cmd prompt and type activate.
It will activate the venv for you.
if you don't want to deactivate or activate the already installed venv just ensure you have set the pythonpath set
set pythonpath=C:\software\venv\include;C:\software\venv\lib;C:\software\venv\scripts;C:\software\venv\tcl;C:\software\venv\Lib\site-packages;
and then execute
"%pythonpath%" %venvpath%Scripts\mytestsite\manage.py runserver "%ipaddress%":8000
The problem is related to this error: Execution Policy Change
Start virtualenv by running the following command:
Command Line
C: \ Users \ Name \ yourdjangofilesname > myvenv \ Scripts \ activate
NOTE: On Windows 10, you may receive an error by Windows PowerShell that the implementation of these scenarios is disabled on this system. In this case, open another Windows PowerShell with the "Run as Administrator" option. After that, try typing the following commands before starting your virtual environment:
C:\WINDOWS\system32> set-executionpolicy remotesigned
Execution Policy Change:
The execution policy helps protect you from scripts that you do not trust. Changing the execution policy might expose you to the security risks described in the about_Execution_Policies help topic at http://go.microsoft.com/fwlink/?LinkID=135170.
Do you want to change the execution policy? [Y] Yes [A] Yes to All [N] No [L] No to All [S] Suspend [?] Help (default is "N"): A
After selection Y(es), close the Powershell admin window, and then go back to the Powershell Window(where you got the error) and run the command again.
> myenv\Scripts\activate and then python manage.py runserver 8085 ,
(8085 or any number if you want to change its default port to work on otherwise you dont need to point out anything. )
I had same problem, I installed all dependencies with root access :
In your case:
sudo pip install django
In my case, I had all dependencies in requirements.txt, So:
sudo pip3 install -r requirements.txt
Just sync your pipenv environment with:
pipenv sync
I had this problem with Django 3.
On manage.py detail the execute_from_command_line import.
You should have:
from django.core.management import execute_from_command_line
Instead of
from django import execute_from_command_line
I had the same problem and my solution was not posted here:
How I got the error
My error came whenever I was installation the requirements.txt file with pip (let's say from cloning a git repository).
Solution
I manually installed each of the modules in the requirements.txt + any other module needed for the installation of those modules (e.g: I got errors and some modules where missing to install other modules so I had to add them too).
If there is anyone who faced with the same problem when using virtual environment and running on MacOS, just try
sudo python manage.py startapp <project_name>
instead of
python manage.py startapp <project_name>
It will solve the problem suprisingly!
I had to install django using the virtual environment pip3 executable directly:
cd [virtual environment folder]/bin
sudo ./pip3 install django
If you already installed Django / configured virtualenv and you still having the error:
ImportError: Couldn't import Django. Are you sure it's installed and
available on your PYTHONPATH environment variable?
Try to run the command pipenv shell before start the server with py manage.py runserver

Django Twilio module is not getting installed on Heroku

I tried below 2 methods to install django_twilio module on Heroku
1) Ran 'heroku run pip install django-twilio'
2) Added 'twilio==3.6.3' to requirements.txt and start the server on heroku.
When I run 'heroku run pip freeze' I can see the twilio entry. But when I go into python and run 'import django_twilio' I get a module not found error.
Please suggest how to fix this on heroku. Same steps worked fine on my local machine.
You didn't add the proper requirement, you only installed the twilio library. Your requirements.txt should include the following line:
django-twilio==0.4
Which will include all the other dependencies you'll need. The full pip freeze, after installing django-twilio looks like this:
Django==1.5.5
django-twilio==0.4
httplib2==0.8
six==1.4.1
twilio==3.6.3
unittest2==0.5.1
As a rule of thumb, always run pip freeze > requirements.txt before pushing an update to Heroku (assuming new dependencies were installed), to make sure you have a complete snapshot of your environment.
