Upload file and primary key - double save
Hi all, I'm developing a site where the object Project is referenced by zero or more objects Image, say basically CODE class Projects(models.Model): pass class Image(models.Model): project = models.ForeignKey(Project) --- I would like to have all images served as 001.jpeg, 002.jpeg and so on, and I'd prefer to host them locally in a per-project subdirectory of my media storage path. I can implement a new save() to create a media subdirectory called with a name containing the Project PK. How can I move all images (previously saved in a directory specified in Image's upload_to parameter) to the new directory? Is the Project's save() the correct place to do this?

Re: Where is "base.html" that "templates/site_base.html" extends?
Hi Christos,
if you put
{% extends "somefile.html" %}
in your template, Django expects to find it in one of the directories
specified in your TEMPLATE_DIRS variable in settings.py.
They are considered in the order they are written, so the base.html you are
extending is the first you find in this sequence.
Hope this helps, feel free to reply

Testing: create db from scratch not working
Hi all,
I developed a Django application (named "manouche") using south. Thus
I have some migrations which build my database.
I want to setup a testing environment where I want to begin with a
clean db, create it with syncdb, migrate my application, load current
fixtures and run tests.
My installed applications are
INSTALLED_APPS = (
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.sites',
'django.contrib.flatpages',
'django.contrib.messages',
'django.contrib.staticfiles',
'django.contrib.admin',
'accounts',
'south',
'manouche',
)
But if I clean up the db and run "./manage.py syncdb" I get the following
Traceback (most recent call last):

Where "stargate" is the name of my project.
If I remove my "manouche" application everything works fine. Then I
put in my application, run "./manage.pty migrate manouche" and be
happy.
However I do not understand why it is not working when all
applications are present in settings.py and how I can automatically
get a complete install, without having to manually remove my
application from the settings.
Any help appreciated, thank you
Leo

Re: Testing: create db from scratch not working
Sure my application depends on the site app, I'm importing Site in my models.py.
But manouche is already at the bottom of the list, so this does not work.

Re: Testing: create db from scratch not working
This is very strange for me: even flatpages depends on Site
/usr/local/lib/python2.6/dist-packages/django/contrib/flatpages/models.py:from
django.contrib.sites.models import Site
but there is no problem in listing both in INSTALLED_APPS and to
syncdb them togheter.
My application depends on Site the same way
manouche/models.py:from django.contrib.sites.models import Site
but I cannot syncdb it with other applications.
No one can help?

Re: Testing: create db from scratch not working
Ok, solved. The problem was the following declaration in my models.py current_site = Site.objects.get_current() which tries to read the current site at registration time, before sites has been properly filled with values. I just replaced every use of current_site with a call to get_current() and everything works.

Forms with FileField - access file content
Hi all, I'm trying to implement a an application where the user creates a new object through a form. Up to here I'm fine. This time though the object creation involves loading a file and choosing some data from it (say choosing some lines, for examples). So I'm a little stuck here. How can I let the user load the file and show the file content in the form itself before submitting? Or is this behaviour wrong for a Web application?

Re: Forms with FileField - access file content
No, I think I didn't correctly explain the matter; say I have a Thing model with a list of strings in it. I want the user to be able to: 1. Access the Thing creation form 2. While editing the form loading a file and being presented with the full content 3. Choosing some lines from that content 4. Submit the form So I need to "modify" the view attaching fields which content comes from what the user uploads. 2011/10/20 Venkatraman S > > On Thu, Oct 20, 2011 at 1:32 PM, Leonardo Giordani < > giordani.leona...@gmail.com> wrote: > >> >> I'm trying to implement a an application where the user creates a new >> object through a form.

Radio button with nested widget
Hi all, I'm trying to implement the following form: a first ChoiceField with values "mode 1", "mode 2" or "manual". Depending on its value I need to show a FileUpload field (mode1 or mode2) or some CharFields (mode3). I'm trying to mimic a desktop GUI, where you can three radio button and each can contain something: a file upload the first two, some text fields the third. Some advices?

Re: Database management commands
This is a problem related to Innodb and MyISAM. Django uses this latter, while probably your imported DB is an Innodb one. Check here https://docs.djangoproject.com/en/dev/ref/databases/ Search Google for the matter too, you are not the only one experiencing it. I would suggest getting rid of the new tables you created, switching to InnoDB and migrating everything. Try and let me know.

Re: create object instance with ManyToManyField
The add() method of a ManyToMany field adds the indexes of the given objects to the field. If you add a list, each index in the list is added to the field. In the admin interface, when you edit a Company object, you see a convenient automagically-created menu which lists all Index object in your application, and there you can add or remove them. But you can add Indexes with the snipped I gave you; if you pass as "my_indices" some of the available Indexes and then edit the object through the admin interface you'll see the ones you added as selected (in blue). *Choices* in the admin interface are build through an automatic query; Django sees that you use a m2m field and populates it with TheTypeYouReference.objects.all() . But this is a service of the forms in the admin interface. Django objects have nothing to do with "choices", they simply know that you are attaching the index of some other object to the object you are creating. Feel free to ask again if the matter is not clear. 2011/10/28 Jaroslav Dobrek : > Hello Leonardo, > > thanks your your answer. > >> n = Company(name=my_name, country=my_country, isin=my_isin) >> n.save() >> n.indices.add(my_indices) > > This causes that the company object has all indices in my_indices > (such as Dow Jones S&P 100, Dax, ...) as *choices*.

Help in adding jQuery to my pages
Hi all,
I'm trying to add a bit of jQuery to a page in a Django site. It seems
that my jQuery scripts are simply not loaded, while JS scripts work
perfectly.
Evan Firebug does not see the jQuery file as loaded.
This is what I do in base.html
{% block javascript %}{% endblock %}
and in my page
{% block javascript %}
{% endblock %}
and my tabs.js is
$(document).ready(function() {
$('li').addClass("active");
}
If I edit jquery-1.6.4.js and add something as alert(), this works
perfectly. Other JS scripts work like a charm.
Any suggestion?
Thank you
Leo

Re: Help in adding jQuery to my pages
Hi, thank you for your detailed answer.
1. I'm on Django 1.3 (1.3.0-final). I'll take a look at staticfiles
for sure, thanks.
2. I'm getting no errors at all, other JS files in that directory load
perfectly. Firefox can reach them in source view.
3. I'll try it, but it seems to me strange not being able to load and
use jQuery as other JS scripts.
Is that jQuery file of mine (tabs.js) wrong? Is there some stupid
error I cannot spot?
No one is experiencing the problem?

Re: Help in adding jQuery to my pages
You are right, sorry.
jQuery is loaded, I can see it in Firefox and in Firebug.
If I write this statement
$(document).ready(function() {
}
in a working JS file, that file stops working, can be reached through
Firefox (it is loaded) but not by Firebug.

Re: Help in adding jQuery to my pages
Sorry Andy and thank for your patience,
as I though the problem is simply simply bad JQuery.
$(document).ready(function() {
$('li').addClass("active");
}
what about some ");" to close statements?

Re: CSS reference to Media folder
I think it is better for you to keep CSS images in /static folder too.
/media is better suited as a folder to host user-loaded content.
If you keep CSS and images in /static you can just refer to them with
a relative path.
I think that probably (but I'm not sure) CSS can only address relative
paths from their location.

Admin custom widget and add new button
Hi all, I'm trying to enhance a form in the admin site for a given model (Django 1.3). The relevant part of the model is the following class Project(models.Model): [...] icon = models.ForeignKey(Icon, null=True) [...] and the admin is a simple call to admin.site.register(). This way I get a very nice form with a drop down menu listing all the Icon object unicode() calls. I would like to replace the widget with an image drop down menu made with javascript, so I did the following class AdminImageSelectorWidget(forms.Select): pass class ProjectForm(forms.ModelForm): icon = forms.ChoiceField(widget=AdminImageSelectorWidget) class Meta: model = Project class ProjectAdmin(TranslationAdmin): form = ProjectForm which is basically just a wrap of the existing structure: by customizing the render() method of AdminImageSelectorWidget I think I should be able to get what I want. First question: is this the correct way to achieve a widget customization? Second question: by doing this I lose the useful "+" button near the drop down menu, which lets the users to add a new object. I found that the class behind this button is RelatedFieldWidgetWrapper, but I do not understand if I can use it on my widget and how. Someone can enlighten me?

Re: Need help figuring out why my { key:value } doesn't seem to be passed to my view by my javascript file.
If I correctly understand you are using jQuery.ajax(). Documentation says
"Data to be sent to the server. It is converted to a query string, if not
already a string. It's appended to the url for GET-requests." So I think
that the ajax() function is calling the URL "/pi/?pathID=somevalue". May
you perhaps check the devel server output?

Re: migrating from django 1.3.0 to 1.5.4, getting ImproperlyConfigured exceptions (AUTH_USER_MODEL refers to model 'auth.User' that has not been installed)
A question to better understand your problem: do you use a custom User
model in Django 1.3?
Did you perhaps set the AUTH_USER_MODEL=auth.User in your settings.py?
If you do not need a custom user model just drop the AUTH_USER_MODEL
setting variable. Otherwise subclassthe AbstractBaseUser and set your
application's user model in the settings.py file.
Let me know if I correctly understood your issue.

Re: Need help figuring out why my { key:value } doesn't seem to be passed to my view by my javascript file.
In Django key:value are sent the way you specify in your urls
configuration. E.g., say that you want to show an object that you can
extract from your DB with year=2013 and month=09 ('year' and 'month' are
here a primary key for that model if used together). The URL schema is
completely up to you, so you could implement the following solutions
basepath/2013/09/
basepath/2013_09/
basepath/?year=2013&month=09
etc, etc
You have just to implement the correct regular expressions in your URL
specification. (I would strongly adverse the second and the third example,
I used them only to exemplify what you can do).
This is what happens with standard GET requests in your views. POST
requests follow the same schema, but they encompass the form data in the
POST section of the HTTP request (that is available through
self.request.POST in your view).
So the problem you have to figure now is: what is jQuery.ajax() doing?
Sorry but I do not know jQuery AJAX, so I cannot help you on this topic.
Reading the documentation I understand that it is issuing a GET on
"/pi/?pathID=somevalue", so I would implement an URL pattern and a view to
catch this request.
Let me know what happens. Regards
Leo

Re: while loop in django
Harjot, with so little information is very difficult to help you, you should try to give a description of your models and exactly what you want to do. What are the "values" and the "job-id" you are talking about? And what about "differences"? About the while loop: in Python it is used this way http://anh.cs.luc.edu/python/hands-on/3.1/handsonHtml/whilestatements.html In Django views (being them Python) you can do the same. In the Django Template Language there is no while loop available. You can write a tag on your own, but I suggest you to try and clarify your issue, so that we can come up with a solution.

Re: migrating from django 1.3.0 to 1.5.4, getting ImproperlyConfigured exceptions (AUTH_USER_MODEL refers to model 'auth.User' that has not been installed)
The way you are creating the DB is quite complicated, but I suspect that you are not syncing the base Django applications before doing your magic stuff. That could be the reason why Django is complaining about the auth.User not being installed. I would do the following: * settings.py with the core apps * syncdb * inspectdb * schemamigration --auto * migrate I strongly feel that your problem has to do with Django processing your models BEFORE doing the base stuff. Can you try this?

Re: Django-cart. How to run method add_to_cart?

Re: Django-cart. How to run method add_to_cart?
Ricardo,
I think the example on the django-cart site are somehow incorrect: since
you are going to change the database you shall use a POST view and not a
GET.
However, putting apart HTTP verbs for a moment, let's look at how you call
views from URLs. If you write something like the following in your views.py
(or whatever file you mapped in your urls.py)
from django.conf.urls import patterns, url
from django.shortcuts import render_to_response
def my_view(request, product_id, quantity):
[do something with product_id and quantity]
return render_to_response('template.html')
urlpatterns = patterns('',
url(r'^(?P\d+)/(?P\d+)/$',
my_view
)
you can browse to http://yoursite/path/1234/56 and have the Python function
my_view(product_id=1234, quantity=56) called.
Try and implement something like the above code and see if it works.
As for the django_cart: when you modify the DB always use POST views and
not GET, then you are right, you have to return a template rendering in
your add_to_cart() view.
Let me know if it comes to life =)

Leo

Re: Django-cart. How to run method add_to_cart?
Hi Ricardo,
well this is a question that needs a good explanation. I try to give you
some hints about what you need to research about:
a. You need to send data to the Django server through a POST view. This is
a HTTP "verb", that is one of many different ways the browser has to
communicate with your server. In particular, POST views in Django work just
like standard views (i.e. GET views), but the request object has a POST
attribute which encompasses the data sent by the browser.
b. To create a POST HTTP request in your browser you need to create a form,
and Django can help you with a very very rich API.
So the general roadmap to achieve what you want is:
1. Set up a POST view that processes the incoming data
2. Link the POST view to an URL
3. Create an HTML template which shows a form to the user and sends data
back to the server.
The 3rd point is obviously needed only if you have to show the user a form
to collect the input he or she enters. You can also call POST views
directly, e.g. including some JS that performs the request, but this is an
advanced topic.
Start by looking at this video
tutorial<http://www.youtube.com/watch?v=gQe_8Q4YUpg>and reading the
docs on Django
Forms <https://docs.djangoproject.com/en/dev/topics/forms/>
I'd suggest you to also check the following resources to understand the
previous two matters:
http://www.w3schools.com/tags/ref_httpmethods.asp
https://docs.djangoproject.com/en/dev/ref/request-response/
http://en.wikipedia.org/wiki/Hypertext_Transfer_Protocol
https://docs.djangoproject.com/en/dev/ref/forms/api/
Feel free to ask more if you need help.
Cheers,
Leo

Re: Custom Filter: Filter output based on a Python list
Ok, now I get the point. I STRONGLY suggest to avoid performing big
computations while rendering templates, so I think it is better for you to
try something like
def results_page(request):
context = {}
context.update(locals())
context['periods'] = {}
for period in ['DECEMBER 2011', 'MAY 2011', 'DECEMBER 2010']:
context['periods'][period] = Results.objects.all().filter(\
reg_number =
'DBA/20020/82/DU').filter()
return render_to_response('results.html', context, context_instance =
RequestContext(request))
and in template
{% for period,results in periods.items %}
[...]
Here you can use {{period}}, which is in turn 'DECEMBER 2011', 'MAY
2011', and so on, and
{{result}} that encompasses the values extracted from the DB.
[...]
{% endfor %}
I included a filter() since I do not know the
models, so I do not know how you can filter out by examination period.
Please note that I would not pass the whole locals() dict to the view, but
carefully select what I need in the template.
Speaking about your filter
@register.filter
def periodofexamination(periodofexam):
periodofexam = ['DECEMBER 2011', 'MAY 2011', 'DECEMBER 2010']
for period in periodofexam:
return period
I think you misunderstood the filter role, which is, indeed, to filter,
things. Here, the input periodofexam variable is not filtered, but
overwritten. Furthermore, you use return in a for loop, so the result of
your filter is 'DECEMBER 2011' irrespective of the input value.
Please check the above code, I wrote it directly in the mail composer, so
bugs are certainly lurking.
Let me know if you succeed in solving the problem

Re: uptodate Account_balance
Maurice,
please remember not everyone on this ML knows finance and noone knows your
application but you.
Moreover, people on ML cannot spend hours trying to figure out what is your
problem: sometimes just solving the problem needs a lot of work, so make
things easy.
You posted your models, but I think you are implementing some views or at
least using them in some code.
Can you give some details about the procedure you are implementing and the
exact issue tou are facing?
Cheers,

Re: Custom Filter: Filter output based on a Python list
Emmanuel,
for examperiod I'd simply write
[...]
for period in ['DECEMBER 2011', 'MAY 2011', 'DECEMBER 2010']:
context['periods'][period] = Results.objects.all().filter(\
reg_number = 'DBA/20020/82/DU').filter(examperiod=period)
[...]
Just be careful when dealing with such comparisons since values must be
exactly the same; to state it clearly: this works always if the period
strings ("DECEMBER 2011", ...) are machine-generated and do not come from a
form (user input).
However, check this
page<https://docs.djangoproject.com/en/dev/topics/db/queries/>which
contains a very detailed analysis of Django query system.
Speaking about the templates: first of all do not take my code as the
source of the truth, things can be done in several ways.
Given that, I try to give you a bigger picture that hopefully helps you
understanding how to step further.
When introducing Django I always stress the separation between views and
templates, which is the base concept of the whole framework (MVT -
Model/View/Template).
Views are Python functions. Their purpose is to produce data and to return
data, just like any function in this world =)
Jokes apart, views are MOST OF THE TIME used to fetch data from the DB
through models and to return templates rendered in HTTP responses, so that
a browser can show them.
So, putting it simply: views extract data, templates show them (this is
somehow simplistic, but is a good starting point).
Templates are text files that are joined with a dictionary through the
Django template language. Most notably you can insert in the template
elements of the dictionary just inserting "{{ key }}" where "key" is the
dictionary key you want to fetch. If the value you get from the dictionary
is an object or another dictionary, you can use the dotted notation to
access its attributes or keys. So if you write in a template {{ obj }} the
template expects you to pass a dictionary which contains the key 'obj' and
some value that can be printed. If you write {{ obj.name }} the template
expects you to pass a dictionary that contains the key 'obj', which in turn
is something that can be accessed through the 'name' attribute lookup; for
example, a Python object with a 'name' attribute.
Context is the dictionary that the view passes to the template when calling
render_to_response().
So my advice was to select what you pass in the context, since passing
locals() is overkill; you pass the template every variable you have, and
this can result in passing a very big dictionary! Moreover, it is not clear
to another programmer (that is you in a month) what the template really
needs. If you template is made to represent a set of objects in table just
extract the set of objects and pass them to the view. To give you an
example:
*MODEL*
class Exam(models.Model):
label = models.CharField(max_length=30)
*VIEW*
def someview(request):
my_list_of_objects = Exam.objects.filter(label='somelabel')
context = {'objects':my_list_of_objects}
return render_to_response('results.html', context, context_instance =
RequestContext(request))
*TEMPLATE*
[...]
{% for obj in objects %}
{{obj.label}}
{% endfor %}
[...]
This can also be written (and is perfectly correct):
*VIEW*
def someview(request):
my_list_of_objects = *[exam.label for exam
in*Exam.objects.filter(label='somelabel')
*]*
context = {'object':my_list_of_object}
return render_to_response('results.html', context, context_instance =
RequestContext(request))
*TEMPLATE*
[...]
{% for obj in objects %}
{{obj}}
{% endfor %}
[...]
(Please note that in the second example I left the previous nomenclature
for clarity's sake - in a real case I'd call the values 'labels' and not
'objects')
Hope this helps you. Regards,
Leo

Are you sure that your DB contains only one entry with that name? Try printing it in the view you use to render that template and check the output of the development server.

Re: Django query from database
I think that you have to perform a query for each Code, extracting the list of Word matching that Code and then merging all the lists. Since I don't know your models, I'll give you some general code, let me know if you understand how to implement it exactly on your models. Assuming that the CodeTable is the representation of a Word model: B = [] for code in A: words = Word.objects.filter(code=code) B.extend(words) This is the basic algorithm. You can then make all sorts of Python magic tricks to shorten it or make it faster, but if you are not dealing with billions of data I do suggest you to keep it simple and readable.

Re: Django query from database
Sorry, I forgot the User part of your question. Let me understand the exact relationship between codes, words and users: do those words or codes come from a form? Or are saved in the DB for each user? I ask this because I want to understand if you are trying to get a relationship that already exists on the DB (so it is a problem of doing good queries and building smart Python structures) or if you are trying to manage some new data the user enters in your site. If you find the time to better describe the exact flow of your application I hope I can help you find a good solution for your problem.

Re: Django query from database
Ok, I think I got the point.
So, correct me if I didn't get it right, you have to get users which have
first_name, last_name, or other fields equal to the words in your list B.
This can be accomplished by looking at each field for each keyword. I would
also compile a dictionary keeping reference of what field matches the search
Continuing the code I wrote above:
users = {}
for field in ['first_name', 'last_name']:
# build something like {'first_name__in', ['David', 'Henry', 'Ostro', '
Henroo']}
filter_dict = {field + '__in': B}
# find all users that match
results = User.objects.filter(**filter_dict)
# store each user and the list of its fields that match the search
for user in results:
try:
users[user].append(field)
except KeyError:
users[user] = [field]
This is perhaps the worst Python code I ever wrote, but I hope you can
tolerate it. Also beware that it is written directly in the mail composer
(so indentation is wrong and code is untested).
Now I realize that the "__in" trick can be used also for the first code I
wrote, try it.
As for the template, you can pass the users dict in the context. In the
template loop over the key/values with
{% for user,fields in users.iteritems %}
{% endfor %}
inside this loop you can further loop over fields with
{% for field in fields %}
{% endfor %}
I am not sure if inside this last loop you can write something like
{{ user.field }}
since I have to check if the template attribute retrieving syntax also
performs getattr. if this does not work you have to store tuples as values
of the users dict, instead of fields, each tuple being (field,
getattr(user, field)).
Try to give a sense to all this stuff and let me know!
Cheers,
Leo

Re: View for creating, listing, and deleting
Hi, you are submitting two different problems, if I correctly understand your question. The first is about Create Read Update Delete objects, the second is about code reuse. 1. CRUD >From the user's point of view you should create a page with the list of objects, then provide a way to selectively delete some of them, and a way to create a new object. For example you could have a button near each object that deletes it, and a general button that creates a new object. The create button shall perform a GET on a page with a form, which in turn, when saved, shall perform a POST. This is done by a view (CreateView, if you want to use class based generic views). The delete button shall perform a POST, and this is usually done by hiding a prefilled form and submitting it through JS when pressing the delete button. 2. Code reuse Since class-based generic views get a model as a parameter, I'd create a Factory, i.e. a class that returns a class. You can then loop over your models and call the Factory, generating urls on-th-fly. Does this make sense for you? Let me know Cheers, Leo Leonardo Giordani Author of The Digital Cat <http://lgiordani.github.com> My profile on About.me <http://about.me/leonardo.giordani> - My GitHub page<https://github.com/lgiordani>- My Coderwall profile <https://coderwall.com/lgiordani> 2013/10/12 > I'm working on a project in which on a certain page I want to have a list > of objects as well as the ability to delete and create them.

Re: AttributeError: 'module' object has no attribute '_handlerList'
As I suspected, there is a problem with the logging module, which is
probably shadowed, i.e. when Django performs "import logging" it imports a
different module.
Try the following: exactly where you execute the manage.py open an
interactive Python shell and do
>>> import logging
>>> print logging.__file__
This should hopefully show us what logging is working behind the scenes.
Try and post the results

Re: def altword_list(self, request, word_id):
Well, I tried to understand the code. Correct me if I did not understand it:
* you are calling AltwordlistView from r'^altword_list/(?P\d+)/$
* being a DetailedView on Altword, AltwordlistView extracts the Altword
with the given pk with a query like Altword.objects.get(pk=pk)
* you set the context you send to the template, in the get_context_data
There, in get_context_data() you have to initialize all the keywords you
are going to use in the template. In this case poll_list.
Note that you define a get_queryset() method in AltwordlistView, but I
think it is not called in a DetailedView, only ListView uses it.
So I'd fix the whole thing this way:
* get rid of get_queryset()
* get rid of the altword_list() function view
* put something like context['poll_list'] =
Altword.objects.filter(word__pk=word_id).order_by('-votes') in
get_context_data()
If you are trying to show a list of objects, however, I suggest you to try
and use a ListView, where you can define your queryset, as you tried to do
with the get_queryset() method.
Try and let me know if something starts to work. Feel free to ask further
if the matter is not clear.
Cheers,
Leo

Re: How to handle values_list?
Andrew, I think that the view is missing something:
def enter_name(request):
my_number = request.user.number
name = Name.objects.filter(pk=my_number).values_list('city', flat=True)
*data = {...}
*
*return render_to_response('template.html', data,
context_instance=RequestContext(request))*
where data is a dictionary with the values you want to be available in your
template. So, for the template you posted, you could write
data = {'name':name[0]}
Here, you need to decide what you need to pass: why do you use filter()
instead of get()? Do you need just one value or multiple?
If you need to pass a list to the template just fill the dictionary
accordingly, but follow Daniel's advice when rendering the list in the
template.

Leo

Re: set-up and usage of mysql in django
What is your exact problem? If you need to use a MySQL server you just need to put the server address and credentials in your settings.py file, then run manage.py syncdb, just like you do with the development server. Everything you did in the tutorial (you did it, right?) is still valid, thanks to the layer called ORM, which maps the DB to Python objects. As for the management you can issue standard SQL commands through the mysql command line tool. I suggest you to use Fabric ( http://docs.fabfile.org/en/1.8/) to automate the process. Feel free to post a more detailed question.

Re: Customizing your project's templates
I think that you are missing the absolute path part of the code comment
*# Don't forget to use absolute paths, not relative paths.
*
This means that you cannot use 'lotus/...'
Usually you use code like
ABSOLUTE_PATH = '%s/'
%(os.path.abspath(os.path.dirname(locals()['__file__'])).replace('\\', '/'))
at the beginning of your settings.py file. Then you can write
TEMPLATE_DIRS = (
*os.path.join(ABSOLUTE_PATH, 'lotus/pollapp/mysite/polls/**templates'),*
# Put strings here, like "/home/html/django_templates" or
"C:/www/django/templates".
# Always use forward slashes, even on Windows.
# Don't forget to use absolute paths, not relative paths.
)
Remember that settings.py is a Python module, so you can use any valid
Python code.
Let me know if you succeed.

Leo

Re: variable in django template
Hi, everything you need in a template can be prepared in a view, so if you need a specific value just pass a context key with that very value. Otherwise, if you need a list of integers, just pass a range(N) list. There is a plenty of builtin filters and tags you can then use to manage it. If you can better clarify what you want to accomplish, I can perhaps be more specific.

Re: formating
I think that the extra space between "floatformat:" and "2" is confusing

Re: formating
What is foundation?
You said that
{{form.valor_ultimacompra}}
works. What about
{{form.valor_ultimacompra|foundation}}
?

Re:
Hi, please include the relevant part of the models and the views when asking such questions, otherwise it is very difficult for people to help you. I'd say that the problem is in the query extracting the values you are showing. You say you do not want number 22 to appear twice: if there are two entries with the same number it is clearly not a primary key, so probably you are filtering on the wrong column.

Re: TypeError: can't subtract offset-naive and offset-aware datetimes
Take a look at
https://docs.djangoproject.com/en/dev/topics/i18n/timezones/#naive-and-aware-datetime-objects
Basically you need to fix datetime objects adding a timezone.

Re: Error while deploying django with mod wsgi
Hi Sebastian, it seems that you are experiencing a name clash or similar. email.quoprimime is included in Python 2.6 (see here http://hg.python.org/cpython/file/3edf679917ba/Lib/email) so if you find it in /usr/lib/python2.6/email/quoprimime.py then you are probably masking the name "email" with something different, perhaps a local Python file. Moreover, you say that you are using a virtual environment, but your traceback refers to /usr/lib/python2.6, so I think that something there is not working as you expected too. May you check your paths? How are you running the deployed package?

it is not really clear to me what you are trying to accomplish. That HTML

Re: order_by result of sum of fields computed from an annotate
Well, indeed the matter is not simple =)
I looked at the raw SQL for your queries and the results are the following
(just print queryset.query to show SQL).
The SQL query for
Author.objects.extra(select={'average_delay':
"Avg('all_books__published_date')-Avg('all_books__added_date')"})
is
SELECT (Avg('all_books__published_date')-Avg('all_books__added_date')) AS
"average_delay", "prova_author"."id", "prova_author"."name" FROM
"prova_author"
so you see that it cannot work, as you stated. Django does not recognize
that extra is working on a joined table, and this because the string passed
to select in extra are unparsed. Documentation states that "Django inserts
the given SQL snippet directly into the SELECT statement".
The other solution you tried is
Author.objects.annotate(first_date=Avg('all_books__published_date'),
last_date=Avg('all_books__added_date')).extra(select={'average_delay':
"last_date - first_date"})
that produces the following SQL
SELECT (last_date - first_date) AS "average_delay", "prova_author"."id",
"prova_author"."name", AVG("prova_book"."added_date") AS "last_date",
AVG("prova_book"."published_date") AS "first_date" FROM "prova_author" LEFT
OUTER JOIN "prova_book_authors" ON ("prova_author"."id" =
"prova_book_authors"."author_id") LEFT OUTER JOIN "prova_book" ON
("prova_book_authors"."book_id" = "prova_book"."id") GROUP BY
"prova_author"."id", "prova_author"."name", (last_date - first_date)
If I correctly remember SQL (not my forte) you cannot refer in the SELECT
clause to aliases that you define in the SELECT itself.
There is some onging work in Django to allow F() objects in annotations so
this perhaps will solve such issues.
Until then I'd suggest you to do the following: the difference of averages
is the average of the differences (in this case, since the number of object
is the same for the first and the second average), so you can store in your
object the difference between published and insertion date, overriding the
save() method. Then you annotate and filter on the Avg() of this new field.
Try and let me know if it works. Regards

Re: Filtering by month doesn't work
Are you sure that filtering using a string is the same as filtering using
an int? I think that Django doesn't automatically convert it. So the
condition
events = Event.objects.filter(end__month='11')
should be
events = Event.objects.filter(end__month=11)
Indeed
documentation<https://docs.djangoproject.com/en/dev/ref/models/querysets/#year>does
things this way. I see that you succeded in filtering with
filter(end_start='2013')
perhaps end__startswith? In that case you are treating it as a string.
May you please check this and let me know?
Cheers,
Leo

Re: OneToOne? Inheritance? Another solution for nested model relationships?
Daniele, I usually solve such issues with Inheritance. I feel comfortable with it because it lets me (in your example) to manage both ResearchStudent and ResearchStaff independently, while keeping the Researcher parent model available to deal with "global" queries and data interaction. As always with inheritance, I suggest to think twice before implementing it, but in this case I'd say that it fits perfectly.

Re: Django get queryset year month day
If I correctly understand you issue is to get part of the date for each
item in a list of datetime.datetime or datetime.date objects.
To do this you can process the list after the query
new_list = [item.year for item in item]
But if your need is to extract fields from the objects in the result list
you may use
values()<https://docs.djangoproject.com/en/1.2/ref/models/querysets/#values>or
values_list()<https://docs.djangoproject.com/en/1.2/ref/models/querysets/#values-list>
.
Let me know if this answers your question.

Re: OneToOne? Inheritance? Another solution for nested model relationships?
I see your point. In this case I'd recommend giving Researcher two foreign keys, one towards a Student model and one towards a Staff one, then add some logic to the model to easily check the actual specialization or to convert it among them. Basically you get a Researcher that "owns" a Student or a Staff role. Does this fit better?
