use python pandas to show csv to placeholder in web file

I have a csv file and need to convert it to view it in html. I know python pandas can do it with

df = pd.read_csv("myfile.csv")
df.to_html('output.html')'

but I don't want to show it in single web page, I have index.html file and I want to show it in there but in another section.

Advice for starting a Flask application

I'm going to create a flask-rest api for my iOS app. When I'm developing the API should I deploy on heroku and every time I make a change commit the code and test it, or should I run everything locally then deploy when I'm finished with the API? I just feel I should test it on production servers then just on my computer locally.

Apache with wSGI Configuration

I have installed Apache2.4.18 on my Ubuntu machine. I can access the 'Apache2 Ubuntu Default Page' from outside my home network, so Apache seems to be working.

I have a working Django website that I can access at my localhost (127.0.0.1:8000).

I need to configure Apache to serve my Django website instead of its Default page.

[Django's guide](https://docs.djangoproject.com/en/1.11/howto/deployment/wsgi/modwsgi/) says to edit Apache's 'httpd.conf' file, but no such file exists on my machine.

[This guide](https://www.thecodeship.com/deployment/deploy-django-apache-virtualenv-and-mod_wsgi/) walks me through the creation of a file that looks similar to what the Django guide is talking about, but there seems to be some major differences between the two.

I don't know where the 'httpd.conf' file should be located. I'm not sure whether the filename needs to be 'httpd.conf' or not. I don't know what information should be contained within 'httpd.conf'.

Thanks for any help in advance!

To use Turbolinks 5 with Django, how can I automate inclusion of the Turbolinks-Location header when using redirect()?

According to the Turbolinks 5 documentation for "Following Redirects" (https://github.com/turbolinks/turbolinks#following-redirects):

> When you visit location `/one` and the server redirects you to location
> `/two`, you expect the browser’s address bar to display the redirected
> URL.
>
> However, Turbolinks makes requests using `XMLHttpRequest`, which
> transparently follows redirects. There’s no way for Turbolinks to tell
> whether a request resulted in a redirect without additional
> cooperation from the server.

And the solution for this is to:

> send the `Turbolinks-Location` header in response to a visit that was
> redirected, and Turbolinks will replace the browser’s topmost history
> entry with the value you provide.

>The Turbolinks Rails engine performs this optimization automatically for non-GET XHR requests that redirect with the `redirect_to` helper.

I have a great interest in using Turbolinks on my Django (1.11) project and I'm wondering if anyone could point me in the right direction of how to create a new Django redirect() function or modify the existing one to always include the Turbolinks-Location header that is needed for redirects to function as expected. I definitely do not want to be manually setting this header every time I do a redirect.

There is a similar entry in the 'Redirecting After a Form Submission' section (https://github.com/turbolinks/turbolinks#redirecting-after-a-form-submission) I would also appreciate any help in understanding how to implement:

> If form submission results in a state change on the server that
> affects cached pages, consider clearing Turbolinks’ cache with
> `Turbolinks.clearCache()`.
>
> The Turbolinks Rails engine performs this optimization automatically
> for non-GET XHR requests that redirect with the `redirect_to` helper.

I did see there is a "Drop-in turbolinks implementation for Django" package on github but this is forked from turbolinks-classic and sourcecode has no mentions of the Turbolinks-Location header so I am sure this is not what I'm looking for.

Python Library for implementing Publish Subscribe model on Raspberry Pi

Hey, guys. Which python library, do you think is best for implementing a Publish-Subscribe architecture.

More specifically, i want to implement such an architecture for passing information between various sensors and actuators in an asynchronous way on a Raspberry Pi, instead of using the traditional infinite main loop approach.

Kindly advise

Revamping design decisions - worth doing now?

So it's been about 1.5 months since I started building a project with Django. Looking at a lot of my old code, unsurprisingly I did not follow best practices. This is especially true with the names of views and models - instead of having a simple model name like **Subscriber**, I'd have something like **UserPremiumSubscription**. There are also major design decisions that I made which were bad, like creating 2 models when I should have just made 1.

I suppose my question applies to not just using Django, but all programming in general - Is it worth going back and changing all the minor nuances to follow best practices? Or should I just keep going and follow best practices for all the code in the future, and go back and do a final fix right before launching the project for production?

It would make sense to go back and fix things now, but what I am worried about is having to go back a 2nd or 3rd time in the future after I become more experienced with Django.

Parsing 1,000,000 Lines of Shell Scripts in 6,000 lines of Python

I thought some people here may be interested in a fairly elaborate parser written in Python.

[OSH 0.2 - Parsing One Million Lines of Shell](http://www.oilshell.org/blog/2017/11/10.html)

Source code:

https://github.com/oilshell/oil

Most of the parser is in the `osh/` directory, and the rest of the shell is in the `core/` directory.

I may be moving away from Python in the near future for speed/size reasons [1], but right now the parser is 100% Python.

There is a good amount of detail on the parser in the blog [2]

Career Advice for an I.T. Field Consultant learning Python

I'm an I.T. field consultant based in NYC working for a MSP and learning Python to expand my skills and market myself for a new job in about a year. I don't have a degree but have managed to come a long way with my knowledge of networking, Linux, macOS, and Windows. I'm extremely calm and empathetic which is also one of my greatest professional skills along with my ability to solve computer problems. I'm learning Python3 and Django currently and I was just curious what job positions I should be looking at to market myself based on my current skill set.

Thanks so much.

Using a form to delete an object

I'm trying to delete an object using a form and DeleteView. What I have right now is giving me an error `Reverse for 'deleteblock' with arguments '('',)' not found. 1 pattern(s) tried: ['classroom/(?P<pk>[0-9]+)/deleteblock/$']` I get this error as soon as I load the template adjust.html.

models.py


class Classroom(models.Model):
BLOCK_NUMBER = (
('11', 'Block 1-1'),
('12', 'Block 1-2'),
('13', 'Block 1-3'),
('14', 'Block 1-4'),
('21', 'Block 2-1'),
('22', 'Block 2-2'),
('23', 'Block 2-3'),
('24', 'Block 2-4'),
)
class_list = models.TextField()
course_block = models.CharField(max_length=10, choices=BLOCK_NUMBER)

class DeleteForm(ModelForm):
class Meta:
model = Classroom
fields = ['course_block']

views.py


def adjust(request):
classroom = Classroom.objects.all()
if request.method == 'POST':
form = DeleteForm(request.POST)
if form.is_valid():
return render(request, 'classroom/adjust.html', {'form':form,'classroom':classroom})
else:
form = DeleteForm()

return render(request, 'classroom/adjust.html', {'form': form,'classroom': classroom})

class BlockDeleteView(DeleteView):
model = Classroom
slug_field = 'id'
success_url = reverse_lazy('classroom:classroom')

delete_block_view = BlockDeleteView.as_view()

urls.py


urlpatterns = [
url(r'^$', views.index, name='index'),
url(r'^classup/$', create_classroom_view, name='classroom'),
url(r'^(?P<pk>[0-9]+)/deleteblock/$', delete_block_view, name='deleteblock'),
url(r'^adjust/$', views.adjust, name='adjust'),
url(r'^random/$', views.block, name='random'),

template - adjust.html


<form action="{% url 'classroom:deleteblock' classroom.id %}" method="post">
{% csrf_token %}
{{ form }}
<input type="submit" value="submit" />
</form>


What I think should happen is the following. /adjust/ points to the adjust view. This view gets all of the Classroom objects and prepares DeleteView form. The modelform creats a choice list with course_block. I get a form with a list and I choose the course_block that I want to delete. When I click on the submit button, the chosen object's classroom.id matches a deleteblock url, which corresponds to the DeleteView for that object. The successful url from the DeleteView goes back to the classroom view.

For testing purposes, in the adjust view if I change the query to `classroom = Classroom.objects.all().first()`, I don't get an error and the form and form submission behave as expected - other than the fact that the form doesn't really do anything because it is classrooom.objects.all().first() that gets deleted.

I've read the documention on the djangoproject but I'm definitely missing something here.

Jupyter Notebook localhost servers...why so many running and how to shut them down...?


My Jupyter Notebook code modules have been running slower and slower...sometimes taking up to 2GB memory...sometimes locking up the system and causing a "Firefox not responding".

When the notebook was running... I used C:>jupyter notebook list...and I checked my Jupyter Notebook servers...

At one point there were 20 jupyter notebook servers listed...why so many...?

There was one localhost 8889 and the other 19 were localhost 8888. Also two severs had different "token" numbers on the same 8888 localhost.

I completely shut down my computer...with the hopes of stopping all the servers and start fresh...hoping to solve my slow programs and memory hog issues.

When I restarted my computer...before I ran any of my notebook programs...I immediately checked my C:>jupyter notebook list...and it showed 5 active jupyter notebook servers...and the Jupyter Notebook was not even running yet.

I did find and use "taskkill /PID 8889 /F" to try to close them...but it either didnt' find it...or...I got "Access Denied. Admin. permission needed (I am already logged on as Admin).

How is this possible that jupyter notebook servers are running before even I ran the jupyter notebook...and is there a way to close them all down to make sure they are not hogging resources...?

Here is the list of servers that came up...before I even ran jupyter notebook.

C:\Users\Robert2\jupyter notebook list

Currently running servers:

http://localhost:8889/ :: C:\Users\Robert2\A iPython Notebooks

http://localhost:8888/ :: C:\Users\Robert2\A iPython Notebooks

http://localhost:8888/ :: C:\Users\Robert2\A iPython Notebooks

Cannot view the image uploaded through admin panel.

Hi everyone, I added a new model in my app that will provide optional images in my blog articles. But I have a problem. My model looks like that:

class Photo(models.Model):
imagename = models.CharField(max_length=200)
aricleimage =
models.ImageField(upload_to=
'blog/static/photos/%Y/%m/%d',
blank=True)

def __str__(self):
return self.imagename

It doesn't look nice because I had to break a few lines to put this code in this post. But anyway, I am able to (after registering) add a photo through admin panel. It creates the directory in the static dir as intended and photo is there and everything seems okay.
But when I try to preview it by viewing this object and clicking at the image URL, I get a notification that the photo with ID:

„4/change/blog/static/photos/2017/11/11/d79yUgm.jpg”

Does not exists and perhaps it was deleted. Well, I know where's the problem but how can I set the django so that when dealing with images it will use the upload directory instead of adding this `4/change`prefix? Thanks.

Interacting with someone elses DRF API, making things easier?

I have limited experience with DRF itself, I work with a fair few other randomly written API's. All of those other ones I've had to write up classes to interact with them..etc. I'm hoping theres something easier for interacting with someone elses DRF.

I've looked into coreapi and I'm struggling with certain aspects, they say to run one command the output should be ... and I seem to get another response such as:

coreapi get http://127.0.0.1:8000
{
"users": "http://127.0.0.1:8000/users/",
"groups": "http://127.0.0.1:8000/groups/"
}

coreapi action list
No current document. Use `coreapi get` to fetch a document first.

coreapi action users list
No current document. Use `coreapi get` to fetch a document first.

What am I missing? This document it speaks of, seems to be something that needs to be done on the server side of things which doesn't help me since I have no control of that nor do they want to do anything for me.
