What is this?

This is a continuation

[Python + heroku] From the state without Python to displaying something on heroku (Part 1) http://qiita.com/it_ks/items/afd1bdb792d41d0e1145

So far I deployed it on heroku and ran it as a sample <Imakoko

heroku update I forgot. It's a classic, isn't it? heroku update

>heroku update
Updating plugins... done. Updated 1 package.
heroku-cli: Updating... done.

It seems that heroku-cli was updated at this time, and it was updated.

virtualenv

to make

virtualenv venv-name It builds the immediate environment settings to switch and use. Venv-name is the environment name. Give it a name of your choice and run it. Here, we will make it orthodox with the name "venv".

>virtualenv venv
New python executable in venv\Scripts\python.exe
Installing setuptools, pip, wheel...done.

Then, now C: \ Users \ (...) \ python-getting-started I'm in, but a folder called venv is created directly under it. There are various Pythons (about 40MB) in it, This is a set of environments that can be polluted.

To enable.

There is an activate.bat, so use it. Then, the environment name will be added to the prompt (at the beginning of waiting for command line input).

`python`


>venv\Scripts\activate.bat
(venv) C:\Users\(Omitted)\python-getting-started>

Hereafter, it will be abbreviated as (venv)>

Edit hello / views.py

Follow the instructions and add the following to the beginning of views.py import requests

In addition, modify the index function

`python`


# Create your views here.
def index(request):
    # return HttpResponse('Hello from Python!')
    return render(request, 'index.html')

↓

`python`


def index(request):
    r = requests.get('http://httpbin.org/status/418')
    print r.text
    return HttpResponse('<pre>' + r.text + '</pre>')

Test locally

After rewriting the index function, test

(venv) >pip install -r requirements.txt
(venv) >heroku local
forego | starting web.1 on port 5000
web.1  | Traceback (most recent call last):

You can check the local environment by accessing http: // localhost: 5000.

git add

git add .

(Then warning: LF will be replaced by CRLF in〜〜 The file will have its original line endings in your working directory. A lot of logs about line feed code are returned. abridgement)

git commit

(venv) >git commit -m "Demo"

*** Please tell me who you are.

Run

  git config --global user.email "[email protected]"
  git config --global user.name "Your Name"

to set your account's default identity.
Omit --global to set the identity only in this repository.

fatal: unable to auto-detect email address (got '{user}@{machine}.(none)')

(venv) >

Hmm Excuse me.

(venv) >git config --global user.email "[email protected]"
(venv) >git config --global user.name "heroku user name"

And commit again.

Confirm with git push

It says git push heroku master, so follow it quietly

Uploading takes some time. About 2 minutes?

Edit the displayed contents

This is the production. This is the index function that I modified earlier,

`python`


    return HttpResponse('<pre>' + r.text + '</pre>')

This part will be the content that will be displayed when you access the index. You just need to give a string to HttpResponse () **.

For example

`python`


def index(request):
    return HttpResponse( str(dir()) )

Like.

(Oh, the commit comment looks like shit, but of course you should add a better poem)

result:

Add other than index

The ** index ** function is called when you access https://ancient-taiga-0000.herokuapp.com/, Then, for example, to make it accessible like https: // abbreviation / test.

Function addition

Add a return HttpResponse () function similar to index. Here, we have prepared a "test" function.

`python`


def test(request):
    return HttpResponse( '<strong>test view !!</strong>' )

Edit urls.py

It seems that you should edit ** urls.py ** directly under the getting started folder along with view.py. This on github,

https://github.com/heroku/python-getting-started/blob/master/gettingstarted/urls.py

`python`


urlpatterns = patterns('',
    # Examples:
    # url(r'^$', 'gettingstarted.views.home', name='home'),
    # url(r'^blog/', include('blog.urls')),

    url(r'^$', hello.views.index, name='index'),
    url(r'^db', hello.views.db, name='db'),
    url(r'^admin/', include(admin.site.urls)),
)

(▲) Because there is such a part

`python`


    url(r'^test', hello.views.test, name='test'),

I added it like this.

with this

You've reached your goal of displaying something, thank you.

Summary

――It was long up and down, but I didn't do much. The latter half is mainly below --Describe the process you want to display in views.py --Register in urls.py --I didn't mention "** env " or " postgrqsl **" in the original documentation. I don't know

It seems that you should prepare an HTML string as if you are using the strong tag in the final test view. Before that, write a process to communicate with an external service, It seems that you can format it and pass it to the HttpResponse function.

So I want to play around with ** external APIs **.
