[Help] Advanced tutorial: How to install my Python package with Virtualenv

[Aline C. R. Souza]

Hello Guys,

I need some help to install my Python package with virtualenv. I follow the 
'Advanced tutorial: How to write reusable apps' and moved the polls 
directory out of the project. Now I want to install my package using 
virtualenv and pip, but I don't know how.

Consider I am inside of my project diretory (where the manage.py is) and I 
am working on a virtual environment. What would be the right pip command to 
install my package, considering that the polls directory is out of the 
project.

Please help!

Re: [Help] Advanced tutorial: How to install my Python package with Virtualenv

[Aline C. R. Souza]

Hello ke1g and gary719_list1,

Thank you for your time.

I am using windows and the cmd terminal. I do not know what you mean by 
activate the virtual env. I created one virtual enviroment called 
'poll-tutorial' and used the command 'workon poll-tutorial' to work on this 
enviroment.

I think you didn't understand my doubt. I think I was not very clear. The 
thing is:

I followed this tutorial: 
https://docs.djangoproject.com/en/1.10/intro/reusable-apps/

At the 'Using your own package' step, there is a choice:  install 
django-polls as a user library or with virtualenv

The tutorial does not explain how to install with virtualenv, so I am 
trying to figure it out.

I saw on a blog post that I should use the pip command as installing a user 
library but whitout the '--user':

pip install django-polls/dist/django-polls-0.1.tar.gz

But did not work, it can not find the file.

I think I am using this command at the wrong directory.

So, suppose that I am at 'mysite' directory, working on the 'poll-tutorial' 
virtual environment. What would be the correct pip command to install my 
package that is inside the folder django-polls/dist outside 
of 'mysite' directory?

I think my problem maybe is just about localization of the files. I am 
little bit lost.

Re: [Help] Advanced tutorial: How to install my Python package with Virtualenv

[Aline C. R. Souza]

Hi everybody,

Pip was working, but I did not know how to use it. Now, I figured out. 

Inside the project directory: 

pip install ../django-polls/dist/django-polls-0.1.zip

Worked fine, the app is running.

Thank you, guys.

NoReverseMatch Error using Django + Haystack + Elasticsearch

[Aline C. R. Souza]

Hello everybody,

I am having a issue using Django + Haystack + Elasticsearch to perform a 
website search.

I made a question on StackOverflow, but I had no satisfatory answer.

The problem is in this line:

by {{ post.author 
}}

post.author.pk works well when called by several views, but it is not 
resolved when called by the search.

There is another way to get the pk of the author of the post?

The link of the StackOverflow question: 
http://stackoverflow.com/questions/40033039/noreversematch-error-using-haystack-elasticsearch

Can someone help me? Please explain in details, because I am new in Django, 
and in haystack, elasticsearch...

Re: NoReverseMatch Error using Django + Haystack + Elasticsearch

[Aline C. R. Souza]

Thank you for your time, Constantine. 

I gave up on following this path. 

I threw away everything that I did on this matter, and I followed the steps 
of this link: http://django-haystack.readthedocs.io/en/v2.5.0/tutorial.html

It took me some time to understand, but now it is working fine.

Thank you.

HELP - Django variable in style (width) attribute

[Aline C. R. Souza]

Hello Guys,

favorite 


Why the template tag call {% get_percentage question.pk choice.pk %} works 
inside the span tag, but doesn't work in style (width) attribute?

What is wrong?

 {% for choice in question.choice_set.all %}
{{ choice.choice_text }}
{% get_percentage question.pk choice.pk 
%}%



 {% endfor %}

I am using Python 3.5.2 and Django 1.10.2

PS: I did the same question on StackOverflow: 
http://stackoverflow.com/q/40065604/5498125, but I have no answers yet.

Re: HELP - Django variable in style (width) attribute

[Aline C. R. Souza]

Thank you both, Constantine and James. Thanks to your comments I could 
realize where the error was, and I could improvve performance assigning the 
returned value to a variable.

The error was in html, and not django. When I looked at the rendered html, 
I could see the error.

Deploy on Heroku Error

[Aline C. R. Souza]

Hello everybody,

I am catching an error on trying to deploy my app on heroku. This is the 
traceback:

  File "/app/.heroku/python/lib/python3.5/site-packages/polls/admin.py", 
line 3, in 
2016-10-20T18:42:46.734824+00:00 app[web.1]:   File

import_module

'models'

[8] [ERROR] Exception in worker process

The app runs normally on localhost.

That is what I tried to do: I went to my virtualenv directory at 
site-packages/polls/ and changed all the imports to polls.models instead of 
.models. Then, I cleaned the cache of the polls app and the cache of the 
blog app (blog app uses polls app). Built my app again and ran it locally. 
The app looks fine. So, I tried to push to heroku and run the app, but the 
same error occurs.

Any thoughts?

Re: Deploy on Heroku Error

Hello Antony,

This is the link to the Poll App: 
https://github.com/alinecrsouza/django-polls-app

The changes I made on the imports (change to polls.models instead of 
.models), I made directly on my virtualenv, I didn't change the polls app 
code. I was afraid of losing some of my previous work reinstalling the 
polls app.

Re: Deploy on Heroku Error

[Aline C. R. Souza]

Hello, Constantine,

I have already followed this article and using `heroku local` the app runs 
fine. However, some things I did different:

(i) I used psycopg2==2.6.2 instead of psycopg2==2.5.3, because the 2.5.3 
version do not works with Visual Studio Community 2015.
(ii) On my Procfile I put: 'web: python manage.py runserver 0.0.0.0:80' 
instead of 'web: python manage.py runserver 0.0.0.0:$PORT', because, for 
some reason, 0.0.0.0:$PORT catches an error of port not found, or something 
like that.

I think the problem occurs only with gunicorn server.

I was thinking in test the app on a linux virtual machine, using the 
gunicorn. However, I don't know how to migrate the virtual enviroment to 
the virtual machine.

So, I don't know if this would be a good approach to solve the problem.

Re: Deploy on Heroku Error

[Aline C. R. Souza]

Hi Constantine,

I did such changes because Gunicorn does not work on Windows, as the 
article itself states. And the psycopg2==2.5.3 does not work with Visual 
Studio Community 2015.
Your comment made me have an idea. I'll try to deploy with psycopg2 instead 
of gunicorn. It is a sample blog for my portfolio, not a real one. And I 
need this work ready this weekend, so if it run with psycopg2, it will be 
ok to me.

I will try it, and inform you if it works later.

Thank you.
