Re: geocoding - getting latlng from JavaScript, send to server, store into MongoDB

[Markus Gattol]

Answering to my own question: this is what I ended up using 
http://dajaxproject.com/maps/ to send coordinates (latlng) back to the 
server (from the users browser) and then store it in MongoDB. I can then 
easily query MongoDB for near points, send the data back to the users 
browser and draw markers on the map. Good stuff!

custom500 page does not show up ?

[Nikhil Verma]

HI All

I have made a custom and a very simple 500.html page. However when i make
debug=False and some error come in website
still it show basic server error message.

"A server error has occurred.Please contact the administrator"

I want whenever there is some error it should show my custom 500 page.

I tried by making a custom function and then setting the handler500="path"
but still with no luck.

Anyone can help in this as to how can i resolve this problem?

Thanks

Re: Dumpdata and serialization issues

[natasha.ba...@utoronto.ca]

Hm, I think the functionality to do this -- at least if I understand 
correctly what I read 
here: 
http://stackoverflow.com/questions/1113096/django-dump-data-for-a-single-model

I'd be fine dumping the data for the entire app -- but the reason I did it 
this way is because when I do this, the category_id field is empty for all 
parts in the Part table. If I look at the database contents, it should not 
be blank -- so not sure why that's happening. So that's why I wanted to 
delve deeper...

So maybe my actual question should be why is the category_id many-to-many 
field showing up blank consistently when I do a dumpdata??

Re: Use regular expression to retrieve all image tags from a given content

It depends on what the OP is using it for.  If it's just for
extraction of images on the page to list them out, and such a tag
comes through, then the OP may be willing to let such
peculiarly-formed tags slide.  However, if the eventual purpose is
to prevent users from adding image tags to a text-area, then it's
perfectly valid (or at least widely accepted by multiple browsers).

And yet I keep coming up with those corner cases, as would any
attacker that wanted to inject an image into the page (again, if the
goal is preventing image injection).  We could still have tags like

  < img class="spoon" src="evil.gif">

and since the HTML spec is pretty lazy/sloppy regarding ignoring
unknown tags, one can even have garbage attributes introduced
anywhere you want:

  

> The point is that if you want nothing but the tags (stripped or
> matched), regular expressions can do the job just fine.

The level of concern varies radically depending on whether one just
wants to extract/gather the sane(ish) image tags from a source, or
if the purpose is to sanitize input.  A rough estimate for
extraction could be done something like the following untested regexp:

 r = re.compile(r"""
<# tag opening
\s*  # optional whitespace
img  # the tag
\b   # must end here
(?:  # one of these things:
 \s+  # whitespace
 (?:[a-z][a-z0-9]+:)? # an optional namespace
 src  # a "src" attribute
 \s*  # optional whitespace
 =# the equals sign
 \s*  # optional whitespace
 (# capture the value
  "[^"]*" # a double-quoted string
  |   # or
  '[^']*' # a single-quoted string
  |   # or
  [^-a-z0-9._:]*" # per HTML spec
  )   # end of the captured src
|# or something that's not src
 \s+  # whitespace
 (?:[a-z][a-z0-9]+:)? # an optional namespace
 [a-z0-9]+# the tag name
 (?:  # an optional value
  \s* # optional whitespace
  =   # an assignment
  \s* # optional whitespace
  (?:  # the value
   "[^"]*" # a double-quoted string
   |   # or
   '[^']*' # a single-quoted string
   |   # or
   [^-a-z0-9._:]*" # per HTML spec
   )   # end of the captured src
  )   # end of ignored attribute
 )*  # zero or more attributes
\s*  # optional whitespace
(?:/\s*) # an optional self-closing
># closing >
""", re.I | re.VERBOSE)

So, that said, I'm not sure it's much more complex to use a real
parsing library :-)

I'm not blithely dismissing them, just making sure that

1) the use case is understood (I haven't heard the OP chime in
beyond the simple code snippet in the first post)

2) the complexity of adequately catching a wide variety of
edge-cases one can encounter when using regexps, and

3) parsing HTML/XML is often better left to battle-tested libraries,
as I'm sure there are missing bits in the above regex...things like
the actual allowable character-sets for attribute names, and there
might yet be some sociopathic code that could slip by, but this
catches most of the cases that occur from my understanding of the
HTML spec.

THAT, I can't give you any grief about--I frequently use that
argument myself :-D

Re: Decoupling Urls

[Nikolas Stevenson-Molnar]

Sorry, I missed the second part of your first question. I would consider
'polls.urls' to be a full path from your project root. Depending on your
configuration, it may also be something like 'myproject.polls.urls'.

Re: Decoupling Urls

[Nikolas Stevenson-Molnar]

Hi Smaran,

Yes, by full path, I mean, for example, 'polls.urls'. And yes, it is a
string. Django interprets it as a module path when it builds up the
URLs. It's the same thing that happens in the polls.urls module when
mapping the URL patterns to functions. The functions are all quoted as
well (in the tutorial). In this case, you /don't/ need to give the full
path, since the 'polls.views' part is specified as the first argument of
patterns. For example, looking at the last code snippet on the page you
linked to, you could write the URL patterns in a few different ways:

1) as-is
2) with no 'prefix' given:
urlpatterns = patterns('',
url(r'^$', 'polls.views.index'),
...
)

3) with a partial prefix:
urlpatterns = patterns('polls',
url(r'^$', 'views.index'),
...
)

4) by passing in the function itself, rather than a string
from polls.views import index
...
urlpatterns = patterns('',
url(r'^$', index),
...
)

This notion of using strings instead of actual references is used
elsewhere too. For example, if you need to create a ForeignKey field in
one model that references a model defined later in the same file:
https://docs.djangoproject.com/en/dev/ref/models/fields/#foreignkey (see
first ForeignKey code example). It's also used in the settings file (all
the apps and middleware classes are provided as strings; typically
nothing is imported in the settings module).

Does that make sense at all? In short, in many places where Django
requires a function, class, or module, you can provide a direct
reference to it, or provide a string instead. You'll still get an error
if the module path in that string is not correct.

Hey Nik,

Thanks for the reply. When you say, provide full path for the lazy quoted
version, do you mean 'polls.url' ?
Is that not relative path?

Also having the path in quotes 'polls.url', is it not a string?

Re: Decoupling Urls

[Nikolas Stevenson-Molnar]

If I understand correctly, you're asking about the difference between
include('polls.urls') and include(admin.site.urls)? Django will often
let you reference modules, functions, and classes 'lazily', meaning you
don't need to import them first. You could use the unquoted version for
polls as well, it would look something like

import polls
...
url(r'^polls/', include(polls.urls))

/or/

from polls import urls as poll_urls
...
url(r'^polls/', include(poll_urls))

Note that if you're using the 'lazy', quoted version you always need to
provide the full path.

Super slow authentication

[Ali Mesdaq]

Hey everyone,

I got a situation where I have SUPER slow authentication like approx 5min
to authenticate with both LDAP and default authentication mechanisms. So
my issue is two parts first is why and how is my authentication so slow?
Second is now I am having some remote users timeout on their
authentication which was not happening before but is happening now. I have
not seen anything in the logs or error messages to help me track down the
cause of this issue. The system is centos 5 and is running apache + wsgi.
The django version is 1.3.

Decoupling Urls

[Smaran Harihar]

Hi Djangoers,

I just completed the tutorial 3 and got a little confused on the last
sectionof
the tutorial,

urlpatterns = patterns('',
url(r'^polls/', include('polls.urls')),
url(r'^admin/', include(admin.site.urls)),)

In this for the polls app, we are assigning the urls.py path in the quotes
'polls.urls'
but for admin we are not?

So what is the difference and being it quotes how does it still pick up the
path? Does django not consider it to be simply string.

Apparently there is. Stepping through their app I found that it calls
has_perm in contrib/auth/models.py, which calls has_perm in
contrib/auth/backends.py, and this controls what specific
functionality each user has access to.

Re: how to save response 's render file to server or email using httpresponse

[Min Hong Tan]

Thx nik,

I'm confused , your words has aroused me  from the word.
"You won't use HttpResponse at all, just EmailMessage (using
message.attach). "

problem solved by using below:



from io import BytesIO



buffer = BytesIO()
book.save(buffer)
excel = buffer.getvalue()
buffer.close()

and just

mail.attach(filename="testing.xls",content=excel,mimetype="application/ms-excel")

mail.send()

and mission accomplished!!

I think that you have to dumdata one or both of the models at the ends
of the many to many,
and the join table will come along for free.

Re: values() and order_by()

[Bill Freeman]

First, I think that you're going about last_visit in the wrong way.
timezone.now() is evaluated once, when the module is imported,
rather than when the user visits.  DateTimeField's auto_now=True
option is tailor made for this kind of situation.

Next, since you have the user id, I'm going to assume that you have
an actual user object.  In the code below I'll presume that it's
request.user .

visits_qs = Visit.objects.filter(user=request.user)
total_visits_count = visits_qs.count()
latest_visit = visits_qs.order_by('-last_visit')[0]

Yes, this is two database queries, but unless you are seeing a performance
issue that you've traced to the fact that this is more than one query, this
code is a heck of a lot more maintainable than trying to make it happen
in one.

Re: how to save response 's render file to server or email using httpresponse

[Nikolas Stevenson-Molnar]

You'll need to use EmailMessage:
https://docs.djangoproject.com/en/dev/topics/email/?from=olddocs/#django.core.mail.EmailMessage

You won't use HttpResponse at all, just EmailMessage (using message.attach).

Re: Conditionals in Templates

[Bill Freeman]

The obvious ways are:

1. Provide a model method that returns a string representing the type
of the instance, compare against that
2. Decorate the instance with an attribute giving the name of the type
as a string...

Can't change the instance (I really think you can still decorate it in
the view, python is flexible that way, but), instead of rows of
instances, return rows of wrapper objects that have the type name as
above, and the original instance as another attribute.

Re: Conditionals in Templates

[Russ Abbott]

Here's a workaround I came up with.

I defined a class:

class TableValue:
def __init__(self, value):
self.value = value
self.is_list = isinstance(value, list)

Then in the Template I wrote


{% for row in rows %}

{% for cell in row %}

{% if cell.is_list %}

{% for element in cell.value %}
{{ element }}
{% endfor %}

{% else %}
{{ cell.value }}
{% endif %}

{% endfor %}

{% endfor %}


Is that considered decent Django?

Re: how to save response 's render file to server or email using httpresponse

dateutil relativedelta compare - strange results

[Cal Leeming [Simplicity Media Ltd]]

Hi all,

Just spent about an hour figuring out what the hell was going on with
dateutil comparisons, and thought I'd share with the group.

Essentially, when trying to compare relativedelta to each other, we were
getting very strange results.

In the end, it was due to the fact 'calendar' needed to be imported -
without this, it seems to do strange things.

Hope this is useful to something else in the future - as we use dateutil
heavily in all our webapps, and this is the first time I'd ever come across
this.

Cal



Proof of concept:

>>> from dateutil.relativedelta import *
>>> relativedelta(years=+2) > relativedelta(days=+7)
True
>>> import datetime
>>> relativedelta(years=+2) > relativedelta(days=+7)
False
>>> import calendar
>>> relativedelta(years=+2) > relativedelta(days=+7)
True
>>>

Conditionals in Templates

[Russ Abbott]

I'm generating a table. I want the cells to be different depending on the 
type of the content. How do I test for the type of the content? I'd like to 
do something like this.


{% for row in rows %}

{% for cell in row %}

{% if isinstance( {{ cell }}, list) %}

{% for element in cell %}
{{  element  }}
{% endfor %}

{% else %}
{{ cell }}
{% endif %}

{% endfor %}

{% endfor %}


But "{% if isinstance( {{ cell }}, list) %}" is not allowed. Apparently I 
can't call a function in an {% if ...  %} tag.  Is there another way to do 
this?

Thanks.

Re: Still need help with the 405....please

[Nikolas Stevenson-Molnar]

Looking at the soaplib source, it looks like it required requests to be
made using POST. If you're loading this in a web browser to test, then
you're making a GET request. Try making a POST request (using something
like Fiddler) instead.

Dumpdata and serialization issues

[natasha.ba...@utoronto.ca]

Hi All,

I'm trying to dump the contents of a table which is the mapping for a
many-to-many field.

The table is called Part and it has a ManytoManyField called
category_id.

When I run python manage.py dumpdata store.part_category_id >
file.json

I get the error Error: Unable to serialize database: Category matching
query does not exist.

I have validated that all values in the table are valid.

The table is defined as follows --> id: integer PRIMARY KEY
unipart_id: integer category_id: integer

Also, when I run dumpdata on the table (python manage.py dumpdata
store.part > file.json), the data is dumped without an error message
but the category_id field is consistently empty in the output.

Any thoughts on what I'm doing wrong?

Thanks,
Natasha

Raise 404

[Smaran Harihar]

Hey Djangoers,

I am on my tutorial 3 and I was on this
topic
.

And now if I try to access http://localhost:8000/polls/1/ it gives me the
same error page, which it gives for other errors.

I know the error is because I have not yet created the detail.html page but
is this the output for 'raise Http404' ?

r'<[Ii][Mm][Gg][^>]+[Ss][Rr][Cc]=[^>]+>' will leave very few corner
cases. The point is that if you want nothing but the tags (stripped or
matched), regular expressions can do the job just fine. It's actually
more complex to do this with parsers, as you have to deal with syntax
errors, keep state and rejoin the tags with the attributes for SAX based
parsers and the only advantageous parser is a DOM tree, which has a
large memory footprint on complex/large documents.
It's a trade-off you should make a decision on, not just blatantly
dismiss regular expressions when a document contains tags or call them
complex when they contain more then two characters. The call can even be
swayed in favor for either by the "I want to learn (regex|XML parsing)"
argument.

def index(request):
latest_poll_list = Poll.objects.all().order_by('-pub_date')[:5]
output = ', '.join([p.question for p in latest_poll_list])
return HttpResponse(output)
What I did not understand, was why did we state,
order_by('-pub_date'), what does that '-' mean before 'pub_date' ?

The reason for using a true parser is to avoid obscure edge cases.
Your example fails on both

  

and

  <  img ... >

Also, depending on the use-case (such as stripping them out of
validated code), a use-case such as

  

could get part stripped out and leave the evil  tag in the text.

Re: Tutorial three '-pub_date'

'-' reverses the ordering of that field. So it will order the most recently

Thanks for the reply.  Removing that did not change the result.  Just
an FYI, but I copied the code verbatim from the snippet.  that's why I
cannot understand what's going on.  I continually get the 405 method
not allowed error regardless.

Oh, and HttpResponse is intended to send data back to a web browser. I

Re: how to save response 's render file to server or email using httpresponse

[Nikolas Stevenson-Molnar]

The content is already rendered when you pass it to your HttpResponse
object. Therefore, I would just write it out prior to creating/returning
the response object. E.g., if you're using a template:

t = get_template("foo.html")
c = Context({...})
content = t.render(c)
f = open('somefile.txt', 'w')
f.write(content)
f.close()
return HttpResponse(content)

However, from the error you mention, it sounds like your either a)
treating an integer like a string somewhere, or b) you are passing an
integer to a function which is expecting a string. Somewhere, something
like this is happening:

a = 5
a.lower() #<-- error

Re: Looking for common practice suggestion.

An intermediate approach would be to generate an initial_data.json/yaml file 
and place it in your project's fixtures directory.  This at least should be 
database independent.

Re: Looking for common practice suggestion.

Well, I guess the user will have to specify the domain and name in the
config file.
I was hoping the information could be provided in the settings file. Only
other way is the
admin system which isn't necessary for an otherwise completely automated
process.

That, and re.match is bound to the start of the string. See:
http://docs.python.org/release/2.7.2/library/re.html#search-vs-match

What you're looking for is:
prog = re.compile(r'')
matches = re.search(prog)

print match

This isn't complex. The email validator in django is complex. Using an
XML parser for this is quite overkill. If you need several elements
based on their nesting and/or sister elements, then an XML parser makes
more sense, or better xpath queries. This is simple stuff for regular
expressions and what they're made for.

But there's nothing inherently built into Django admin that supports

Yes, I have seen some very impressive admin media controls for websites

I have a client that asked me to add some new functionality to their

Looking for common practice suggestion.

[Robert Steckroth]

Hey Gang, I am writing a framework to install django projects to the cloud.
Currently I have the user specifying
the site domain and site name in a config file for the django.sites
framework and providing the site_id in settings.py.
Personally, I change the django.sites entries by issuing mysql commands to
the database.
Can any of you provide the most common/best way that the
django.sites object is created?
Is it usually provided in the settings.py file? Or is a database change
your current method?
The docs don't seem to get into how this object get created. Also, is this
object created with the syncdb command?
Much thanks to any help.

Re: Still need help with the 405....please

I'm not sure that this is the problem, but typically constructors should
not have a return value. Try removing the "return" from your
DjangoSoapApp constructor.

Inheriting template with a form into an existing template

[DF]

I have a simple note taking part of my application I'm trying to converge 
into one template. Currently, I have one template and view that renders and 
posts the form and another that displays the results. I'd like to 
amalgamate these into one where the form exists and the results are 
displayed on the same page.

This seems to be something that be achieved with template inheritance, but 
I'm not sure how to alter the views so that both of these results can 
appear in the same template. I've looked around for answers but can't seem 
to find what I need to achieve this. Any help that could also inform me on 
how to properly achieve this moving forward would be appreciated. This is 
one of those areas I've been anticipating learning but it's been more 
difficult that I assumed. The essential code is posted below:

Views for submitting and displaying notes:

@login_required
def submit_note(request):
if request.method == 'POST':
notes_form = NotesForm(request.POST, request.FILES)
if notes_form.is_valid():
new_note = notes_form.save(commit=False)
new_note.author = request.user
new_note.save()
return HttpResponseRedirect( "" )
else:
notes_form = NotesForm()
return render_to_response("write_note/notes.html", {'form': 
notes_form}, context_instance=RequestContext(request))

@login_required
def all_notes(request):
all_notes = Notes.objects.all().order_by('-date')
paginate = paginated_stories(request, all_notes)
return render_to_response("report/notes.html",
   {'notes': paginate},
context_instance=RequestContext(request))

Current basic templates to submit and display:

{% extends 'base.html' %}
{% block page_title %}Notebook{% endblock %}
{% block headline %}Notebook{% endblock %}
{% block content %}
Write and save notes, quotes and other story info



{% csrf_token %}
{{ form.as_p }}





{% endblock %}

{% extends 'base.html' %}
{% block page_title %}Notebook{% endblock %}
{% block headline %}Notebook{% endblock %}

{% block content %}


{% if notes %}
{% for note in user.notes.all reversed %}
{{ note.title }}
{{ note.date }}
{{ note.copy }}
{% endfor %}
 {% else %}
You have no notes stored.
 {% endif %}


{% endblock content %}

And the two urls:

url(r'^write_note/$', 'stentorian.report.views.submit_note', 
name='write_note'),
url(r'^notes/', 'stentorian.report.views.all_notes', name='all_notes')

get_or_create() race condition MySQL - second fix!

[Cal Leeming [Simplicity Media Ltd]]

Hi guys,

A while ago we released a monkey patch which resolved the get_or_create()
race condition when used in combination with READ COMMITED transaction
isolation.

However, this caused issues with legacy applications, so we have released a
new fix that works without READ COMMITED.

The code snippet can be found here, along with details:
https://code.djangoproject.com/ticket/18557

Thanks

Cal

Re: Advices on what web programming language used in template?

[Frankline]

Hi Yu,

Your question is not really clear. Perhaps take a look at this:
https://docs.djangoproject.com/en/dev/topics/templates/

Since you have mentioned JSP, I'm thinking you are looking at Python/Django
alternatives. If that is the case, then you have the following alternatives:

- Ruby on Rails
- PHP
- Java/JSP/Spring or Struts and even JSF

But then again, it would help if you were more clear on what you need. This
is 'mostly' a Django forum.

Frankline

Any chance pybbm started messing with the session storage backend and

Re: to add counter in the project

[Bharati Sharma]

sorry  kenneth ...but I have stored information(resume) of professors in
the database.
in models.py , i have taken fields like name, dob,
qualification,designation etc. then these are saved in the database of
every professor.
but the point is designation of professors vary(like there are professors,
assistant professors and associate professors).I want that it should count
 the no of   professors, assistant professors and associate
professors automatically and increments their value after I fill and save
the next resume in the database. Is there any logic like this...plz help
me. I shall be very thankfull.

if you want to know the number of assistant profs do a query like this:

no_of_asstprofs =
Faculty.objects.filter(job_title='AssistantProf').count()

do not store this in the database - call it when you need it. If you
have a counter, you need to maintain it - increment when adding, reduce
when deleting - which also means setting up signals to adjust the
counter when a model is changed. A huge waste of time and energy.

Re: to add counter in the project

[Jon Black]

It sounds like you have different user's (User) with different
roles (Group with permission set) that have a resume:

class Resume(models.Model):
  resume = models.FileField()
  date_uploaded = models.DateTimeField()

You can then query by aggregating across the group and
date_uploaded fields. That's one option.

values() and order_by()

[J. Javier Maestro]

Hi there!

I have the following model:

  class Visit(models.Model):
  user = models.ForeignKey(User)
  visitor = models.ForeignKey(User, related_name="visitor")
  last_visit = models.DateTimeField(default=timezone.now())
  count_visits = models.IntegerField(default=0)

I would like to make the following SQL query using the Django ORM:

  SELECT last_visit, SUM(count_visits) AS total_count_visits
  FROM core_visit
  WHERE user_id=42
  GROUP BY user_id
  ORDER BY last_visit DESC

So far, I haven't been able to do it. When I use values('user') and
order_by('-last_visit') the last_visit column is automatically added
to the GROUP BY clause. I've read in the Django doc that this is how
it's supposed to be but I can't seem to understand it. Why do I have
to group the results by whatever I choose as order? What am I missing?

Also, I know I can do a RawQuerySet but unfortunately, I would like to
be able to use a full QuerySet (this query goes into Tastypie and so
far, I haven't been successful in using it with anything but full
QuerySets, not even ValueQuerySets...)

All help and ideas would be greatly appreciated.

Thanks a lot in advanced,

Re: Deployment: Apache2, wsgi (Debian squeeze)

[Rohan]

If you change '/django' to '/' in your WSGIScriptAlias directive, then 
everything will be forwarded to django, but apache will no longer check 
in DocumentRoot since all url paths begin with a '/' and will be matched 
by your wsgi alias


This means you would need another way of handling static content that 
doesn't need to be rendered by django. I personally use an nginx proxy 
in front of apache which serves static content directly and forwards 
dynamic requests to apache.


In answer to your question of how you handle the same problem through 
urls.py, you can use the django static files app as explained in 
https://docs.djangoproject.com/en/dev/howto/static-files/


For example, having the following in urls.py

url(r'^media/(?P.*)$', 'django.views.static.serve', 
{'document_root': settings.MEDIA_ROOT,}),


lets django serve requests beginning with '/media' directly if your 
media files are located at MEDIA_ROOT simlar to how apache serves 
content from DocumentRoot. However, as the django documentation 
explains, this is highly inefficient, and NOT recommended for production 
since webservers do a better job of handling static content. As Kenneth 
suggested, setting up a virtual host in apache is an excellent way to 
start off.

I would suggest that you start with trying to understand the concept of
virtual host in Apache. Try to set up a virtual host serving static
content at the start and once you understand that, things will start
falling in place (I am from a similar background from you, and thats how
I did it.

If you want a counter in database, you can make it auto-increment.
Like I want job_no as a counter field in a table, then in models.py, add this :

job_no = models.AutoField(primary_key=True)

But if you want the counter in tables in the template file then add
{{forloop.counter}} as your table field.

Correct me if I am wrong anywhere.

Re: Can't figure out how to obtain organized list of my friends

[Jon Black]

I agree with Kenneth. Your models seem odd. Why not use a
ManyToManyField? The django docs even provides quite a nice example
(see:
https://docs.djangoproject.com/en/dev/ref/models/fields/#django.db.models.ManyToManyField.symmetrical):

  class Person(models.Model):
  friends = models.ManyToManyField("self")

You could adapt this to your UserProfile I suppose.

That's quite a vague requirement. You could override form_valid()

Re: Same virtual-env for all django projects

[Jon Black]

Bear in mind that you may want different packages in your
environments depending on the project. For example, you may have
a project that uses a maps app (from pip) which isn't required by
others. The general purpose of virtualenv is to setup clean,
self-contained environments. What would you do if one project had
a dependency that required a new version of another package that
another project can't use. :) Moreover, if you start using
virtualenvwrapper hooks (e.g. switch to the project directory
when 'workon' is called), it won't make sense anymore if you
share an environment.

Maybe I'm being a bit extreme, but it was a thought. Only you can
judge your needs.

I would suggest that you start with trying to understand the concept of
virtual host in Apache. Try to set up a virtual host serving static
content at the start and once you understand that, things will start
falling in place (I am from a similar background from you, and thats how
I did it.

Re: Difficulties deploying Satchmo store

[ionic drive]

and is there any good reason why you go for django version 1.1?

or do you only not bother about framework versions?

to get a list of friends of a particular user this may work:

first get the user:
me = Profile.objects.get(user = myuser)

then get the friend1
friends = me.fiiend1_set.all()

the confusing thing about your models is that it seems to me that your
Friendship model should be split into two models.

Re: Difficulties deploying Satchmo store

Dear Jonathan,

I know a lot of things about you... you are an Orthodox Christian
Author, your skills are Ajax, CGI, CMS, CSS, Django, HTML, IA, JSON,
JavaScript, LAMP, Linux, Perl, PHP, Python, SQL, UI, Unix, Usability,
UX, XHTML, XML,...
I know you only check the first results in search engines, I know you do
not investigate in alternative search terms...
This things I know, because you investigate a lot to tell us.

But I have no clue what you are going to achieve.
You do not ask specific questions.
I have no clue what servers you try to run. Apache, NGINX, Caudium,
Goron, Zope...

I did not tell you that this link will solve all your problems, it only
should help you to start going.

Jonathan my friend, this is not an easy task, you will need to
investigate more time in search engines and reading than in your
signature.
Sorry, but this are the hard facts.

Again good luck
io

Deployment: Apache2, wsgi (Debian squeeze)

[Matt Smith]

Hi,

I made a multi choice quiz using django and was able to deploy it at:

http://mattsmith.org.nz/django/test

Thanks to the community for making these tools available.

I am a self-taught programmer, this is the first time I have tried any 
web development so please be patient. I always find these groups 
intimidating but I really feel I have made a decent RTFM effort before 
making this post.


Here are some things I know nothing about:

Apache configuration.
How http actually works.

Up until now I've been serving non-dynamic content the usual way. I 
apt-got installed apache2, worked out /var/www was the root, followed 
the index.html convention and that worked fine. Now I feel I'm stuck 
between that old way of doing things and the django/wsgi way which I 
can't get my head around even after reading the docs. The development 
server experience hasn't helped me much when it comes to deployment.


I wanted to connect the quiz to http://mattsmith.org.nz/test instead of 
http://mattsmith.org.nz/django/test but I couldn't see how to do that.


I also want to convert the whole site to django so I can use child 
templates, but I cant work this out either.


I guess my main question is this:

Under the old scheme if someone types just my domain into their browser 
they get $DOCUMENT_ROOT/index.html, simple. What is the equivalent for 
the django/wsgi setup.? What do you put in urls.py?


After reading the docs (they all say different things) I ended up with 
the following setup:


/var/www/{oldStuff}
/var/django/dogscience/apache/django.wsgi

To help you help me you can see the following files from my system at 
http://mattsmith.org.nz/pleasehelp


/etc/apache2/httpd.conf
/var/django/dogscience/settings.py
/var/django/dogscience/urls.py
/var/django/dogscience/apache/django.wsgi

Thank you,
