is this (online tutorial) code calling a view from a view?

[Andrew Taylor]

Hi,

I've been following an online tutorial but been debugging. I've traced my 
issue to this line in the view function below:

return category(request, category_name_url)


Is this view effectively calling another view directly without going via 
the urls file (in the exception case)? If so can you advise me if this is 
good or bad practice?

Thanks,


Andy



from rango.forms import PageForm
def add_page(request, category_name_url):
context = RequestContext(request)

category_name = decode_url(category_name_url)
if request.method == 'POST':
form = PageForm(request.POST)

if form.is_valid():
# This time we cannot commit straight away.
# Not all fields are automatically populated!
page = form.save(commit=False)

# Retrieve the associated Category object so we can add it.
# Wrap the code in a try block - check if the category actually 
exists!
try:
cat = Category.objects.get(name=category_name)
page.category = cat
except Category.DoesNotExist:
# If we get here, the category does not exist.
# We render the add_page.html template without a context 
dictionary.
# This will trigger the red text to appear in the template!
return render_to_response('rango/add_page.html', {}, context)

# Also, create a default value for the number of views.
page.views = 0

# With this, we can then save our new model instance.
page.save()

# Now that the page is saved, display the category instead.
return category(request, category_name_url)
else:
print form.errors
else:
form = PageForm()

return render_to_response( 'rango/add_page.html',
{'category_name_url': category_name_url,
 'category_name': category_name, 'form': form},
 context)

Form that includes one2many relation

[ctm7]

Hello Users,

I am currently developing my get to know django project an Invoicing 
application. I currently developing my forms and I'm trying to figure out 
how to make a form that allows you to create an invoice *and* at the same 
time make invoice lines. My invoice line model has a foreign key relation 
to my invoice model.

This *is* possible within the Admin interface and is as simple as adding an 
inline view to my InvoiceAdmin model.

Any suggestion for which direction to go in?

Many thanks,

T

Python-requests call within view hangs LiveServerTestCase

[Ashwin Raju]

I have implemented a REST api using django rest framework. I am now 
implementing a website to prove consumption of the rest api. So in my view 
code, I validate the form input then use python-requests to call the api. 
This is so that in the future, mobile clients can directly consume the api.

I have a functional test for this using LiveServerTestCase and Selenium. 
When I do the scenario manually, it works correctly. However, the 
functional test hangs on the python-requests call. I've used a POST in this 
example, but GET using the python-requests api has the same effect.

My sample code is in this stackoverflow 
question: 
http://stackoverflow.com/questions/21690718/liveservertestcase-hangs-at-python-requests-post-call-in-django-view
 

One thing that is interesting about this pattern is that the web server 
will receive a second request from within the first request. I don't think 
this is a db lock issue since LiveServerTestCase derives from 
TransactionTestCase, which doesn't take any transaction locks. So why does 
this scenario fail with LiveServerTestCase when it passes with manage.py 
runserver?

Thanks,
Ashwin

Re: Question about the send of file versus the django server

[simone monteleone]

Hi Russ,

My goal is to load the csv file directly in the database.

So my idea is define a script containing the follow pseudo-code:

 while(1) and receive_csv():

value1, value2 = read_csv()
   
MyModel.objects.create(field1=value1, field2=value2) 

The script run on the server, ex http://127.0.0.1:8000/admin

At this point it's possible using the script reported?







*import requestsurl = 'http://127.0.0.1:8000/admin'files = {'file': 
open('log', 'rb')}r = requests.post(url, files=files)*

I don't understand where send the file respect the Django server.

Thanks very much.

SM

Not exactly, Aptana does have PyDev as part of it (might be optional).
Which gets you about the same as Eclipse+Pydev. For those that don't
know Aptana is a custom variant of Eclipse oriented to web development.

Pydev is django aware and virtualenv capable. If you have pydev
installed you'll notice that you can start a new Django project from the
Eclipse menus.

Look for information about Pydev and Django it should be relevant to Aptana.

The steps I would take, make new django project in the IDE. git init,
add, commit and push this structure to your github repo. Make sure to
gitignore the file you store your database password in.

Enjoy,
Alex

First tutorial - 404

[Steve Booth]

I've been Googling on this for several hours.  Time to ask.

I'm just trying to run through the very first tutorial, and frankly, it's 
been a nightmare. Running under Fedora 18, Python 2.7, Django version is 
1.4.5.

So, I got the 1.4 tutorial up, created the site.. all works fine.  Fire up 
the server -- looks great.  Browse to http://127.0.0.1:800..

And I do NOT get the nice, blue Django page, I get a Page Not Found 404 
error telling me the URLconf in mysite.urls does not match '^admin/'

Well... YEA!  So either the 1.4 tutorial doc's are wrong, or the default 
site doesnt work, or I dont know what I'm doing.

Any help would be greatly appreciated. 

I shouldn't have to be asking this ... it should just work.

Re: Newbie Question - Where to store application constants?

[Camilo Torres]

To round this, for the price of gold, and if you are using the 
django.contrib.admin interface, you can use Django Solo or similar 
singleton model. That way you can edit your "business properties" within 
the admin interface:
https://pypi.python.org/pypi/django-solo

1. createdb is a Postgres utility for the command line. May be you don't 
have Postgres propertly installed or configured in your system.
2. ogrinfo is an utility from the GDAL project:

may be you don't have it properly installed or configured

Re: or-ing to QuerySets turns INNER into LEFT OUTER joins?

That is not a MySQL issue with outher joins, nor any other RDBMS issue with 
outher join. That depends so much in the way you wrote your query and the 
conditions for joining you are putting in; you can be doing a full table 
scan or cartesian product of two (or more) relations. The index are used 
whenever possible or whenever the RDBMS is able to use them.

Carsten's manual optimization seems better than that of the ORM for this 
case.

Re: Question about the send of file versus the django server

Do you want the *file*, or the *data contained in the file*?

Based on the script you've provided, you want the *data*. If so, you don't
run a script like this at a URL. You run it at a Python prompt.

When you went through the Django tutorial, the first steps were all done at
a prompt. Those commands let you inspect the data that was in the database.
You can also use the prompt to *create* data in the database - that's what
your script needs to do.

You don't need to upload the script to the server, or write any view code -
you're writing a set of commands that you will run at a prompt to open a
file, read some data, and write to the database. Then you can start your
Django server, and see that data *on* your server.

Is that more clear?

Yours
Russ Magee %-)

Re: First tutorial - 404

[yati sagade]

The tutorial for 1.4 can be found here:
https://docs.djangoproject.com/en/1.4/intro/tutorial01/ (For other
versions, just change the 1.4 in that URL to the version you'd like). I am
curious, is there a reason you want to continue learning with 1.4, like you
are stuck with it for some reason? If not, why not just upgrade? (I'm sure
you'd have thought about this, but as I said, I'm curious :))
