model save question

2011-08-16 Thread Mike Dewhirst


When using save() in a model, what is the difference between ...

save(self, force_insert=False, force_update=False) or
save(self, force_insert=False, force_update=False, **kwargs)
# whatever
super(Xyz, self).save(force_insert, force_update) or
super(Xyz, self).save(force_insert, force_update, **kwargs)

and

save(self, *arg, **kwargs)
# whatever
super(Xyz, self).save(*args, **kwargs)

I see the former in a fair bit of django example code around the place 
and the latter in the docs here


https://docs.djangoproject.com/en/dev/topics/db/models/#overriding-predefined-model-methods

..or hard-code relative links in your templates.
I was thinking about the file:/// un your urls; not the best idea but
they are absolute and will work on your local machine.

We know your template is rendering because

Were you using firefox before?  If yes, that security error should
have nothing to do with it.  My reasoning is
some, if not all of your file:/// urls are being used by FF -- since
the double-click event is being handled, and then the table appears.

Hmm the workaround MS suggests actually works, so I have a

There's no practical difference right now. The main reason for the (*args, 
**kwargs) format is for forwards compatibility: if Django introduces a new 
argument to `save` in future versions, your code might stop working if 
you've hard-coded the function to only pass two parameters.

[ANN]: FeinCMS v1.4.1 final

2011-08-16 Thread Matthias Kestenholz

Hello everyone

I failed big time when creating the v1.4.0 release and created the
package from the wrong version...

Anyway, we're back on track now. v1.4.1 is available at the usual
places with the contents v1.4.0 should have had.

I'm sorry for any problems caused by this blunder.


Best regards
Matthias

So, you don't state your django version.

I think either your template, or perhaps some combination of your
template and the admin templates, is loading the future version of the
url tag. The future version does not interpret a constant as the view
name, but as a context variable which it then resolves. I guess
'geocoding' doesn't correspond to a context variable, and hence the
error message.

Does it work if you quote the view name? Eg:

{% url "geocoding" %}

Cheers

Tom

Re: Convert dictionaries to django model (recursively)

The only piece of Django I can think of which would do that sort of
things is the serialization framework.

While it does not (as far as I know) expose any interface to
serializing objects as Python dicts and arrays, it does support
serializing to JSON (although the structure is a bit more complex
than what you show here as it stores the instance's model at a
higher level of the structure than the raw field values), it should
be a good start towards vivifying simple dicts into complete object
structures.

Therefore, I would recommend looking into serializers and how they're
coded, and maybe just rework your dict structure a bit and add a new
serializer to/from python dicts (I'm not sure how pluggable django's
serializers are, but considering there's a SERIALIZATION_MODULES[0]
settings key I'm guessing you can add pretty much anything you want,
and some googling leads me to think it's even possible to replace
the built-in serializers[1]).

Re: Use object (User and custom object) in a form

2011-08-16 Thread nicolas HERSOG

Oh I see,

I've just modified my code with new import but i still have problem to
submit my form. I don t have any errors but i can't pass the
form.is_valid().
It's my first form so i don t know how to do it. Can you (again) help me ?

Here it's my forms.py :

from django import forms
from django.contrib.auth.models import User
from myApp.models import Article

class CommentForms (forms.Form):
cf_comment = forms.CharField()
cf_writer = User()
cf_date = forms.DateField()
cf_video = Article()

my template :
(...)
 {% csrf_token %}






(...)

and my view.py :

def article(request, id):
article = Article.objects.get(id=id)
commentaires = Commentaire.objects.filter(video=video.id
).order_by("-dateComment")
#dateTime
date = datetime.datetime.now()

c = Context({
'article' : article,
'commentaires' : commentaires,
'now' : date,
})
 # preparation du formulaire de commentaire
if request.method == 'POST':
form = CommentForms(request.POST)
if form.is_valid(): #validation
cf_comment = form.cleaned_data['commentaire']
cf_date = form.cleaned_date['time']
cf_writer = form.cleaned_data['user']
cf_article = form.cleaned_date['article']
print 'IF'
else :
form = CommentForms()
print 'ELSE'


return render_to_response('myApp/article.html', c,
context_instance=RequestContext(request))


When i submit my form i can see via the python console that i m only in the
ELSE of the form.is_valid, and when i inspect via firebug what i submit in
my form i have :
commentaire test commentaire a2
csrfmiddlewaretoken c25f76451eba14ebb762bb4ed4795274
time 16
user username
vod Final

any idea ?
Great thx for your help :)

Re: Template html works when double clicked but empty when accessed through server

2011-08-16 Thread Konstantin Sushenko

you do not see anything because the style on your root element is set
to "display:none" and the browser does not run scripts because they
are loaded from local URLs. as it says: it is a insecure to execute
scripts from local URLs. suppose you publish this page on your
production server, where would your visitors get there scripts? they
are not on their machines in "d:/django-1.3...". basically, it is
unclear to me what you are trying to achieve.

You aren't rendering your Form, you are manually outputting a form.
For one thing, this means you won't see the validation messages from
your form.

If request.method != 'POST' then you don't create the Form object
(which might explain why you were rendering by hand).

Find out why the form validation fails and fix it.

Look at the how the manual describes how to create a form, use it in a
view, and render it in a template. Compare and contrast this with your
view, and how you handle and render your form.

https://docs.djangoproject.com/en/1.3/topics/forms/#using-a-form-in-a-view
https://docs.djangoproject.com/en/1.3/topics/forms/#displaying-a-form-using-a-template

Re: Weird hyperlink issue with Office and Django authentication

2011-08-16 Thread Konstantin Sushenko

as the article says, their sessions are independent of these used by
the web server. the cookies are not shared between office sessions and
web sessions. I think django has nothing to do with it.

M2M with self throught int. table, how to access related items?

2011-08-16 Thread Yaşar Arabacı

Hi,

I am not a django guru (yet) and I am having what I would guess a
trivial django question. Here is my table setup stripped:

class Post(models.Model):

relevancy =
models.ManyToManyField("self",through="Traffic",symmetrical=False,related_name="relevant",blank=True)

class Traffic(models.Model):
tfrom = models.ForeignKey(Post,related_name="tfrom")
tto = models.ForeignKey(Post,related_name="tto")
count = models.PositiveIntegerField(default=0)

This is to be a simple visitor tendency tool, which I keep records of
which link clicked on which post. I am confused about, getting related
items. For example, given a post, how to get set of posts which have
traffic from the post (post.tfrom_set ? ), or how to get post with a
max "count" which is trafficked to the post
( post.tto_set.max("count") ? ) etc.

PS: English is not my main language. Sorry if I wasn't clear

Re: model save question

2011-08-16 Thread Yaşar Arabacı

Absence of **kwargs would cause problems if for example save method is
called with "using" keyword argument. You could either list all the
available keyword arguments or use **kwargs.

By the way, is there any other kwarg for save?

Re: Weird hyperlink issue with Office and Django authentication

2011-08-16 Thread Michel30

Yes I agree, but if I understand it right then the article suggests
that the issue originates from the single sign-on mechanism, in this
case the Django authentication backend. This should be smart enough to
handle the multiple sessions.

Anyway I had a hard time finding anything related on the web including
a fix.
So for future reference, here it is.

httpresponse creates file in /tmp

2011-08-16 Thread sebastiaan

Hi,

currently I'm working on an application that serves PDF files using
HttpResponse:

f = open( pdfFileName, 'r' )

response = http.HttpResponse( f.read(), mimetype='application/
pdf' )
response['Content-Disposition'] = 'attachment; filename=%s' %
pdfFileName

f.close()

return response

Problem is that HttpResponse creates the served file in /tmp which is
not desirable.

Anyone have a suggestion?

PS: I've also tried with StringIO, same result.

I wasn't aware django buffered responses into TMPDIR, however...

HttpResponse either takes a string or a file-like object. When you
pass it a file-like object it reads it in chunks and outputs it in
chunks. You're passing it a string, but you could just pass it the
file handle, in which case it would output it in chunks*.

Cheers

Tom

Re: help error in form usage

2011-08-16 Thread Tom Evans

Your form is not a model form, and so you cannot pass instance=post.
Since it is just a regular form, you should pass a dictionary of
values, with the keys of the dictionary being the names of the fields.

If the form is representing a model, you should be using a model form.

https://docs.djangoproject.com/en/1.3/topics/forms/modelforms/

Cheers

Re: httpresponse creates file in /tmp

2011-08-16 Thread Landy Chapman

The example here:
https://docs.djangoproject.com/en/1.3/howto/outputting-pdf/

does not use a file; it uses the a file-like object: HttpResponse.
That is how my code does it. When I get back I will check if my pdf
report also creates a file in /tmp

Hi, another question from a Django beginner.

Re: Json serialization help

2011-08-16 Thread Nate

Thank you for the suggestion.
I actually ended up extending Django's json serializer.  Here is the
code in case you or someone else needs to do something like this.

from django.core.serializers.json import Serializer as JsonSerializer
from django.utils.encoding import is_protected_type
class DisplayNameJsonSerializer(JsonSerializer):

def handle_field(self, obj, field):
value = field._get_val_from_obj(obj)

#If the object has a get_field_display() method, use it.
display_method = "get_%s_display" % field.name
if hasattr(obj, display_method):
self._current[field.name] = getattr(obj, display_method)()

# Protected types (i.e., primitives like None, numbers, dates,
# and Decimals) are passed through as is. All other values are
# converted to string first.
elif is_protected_type(value):
self._current[field.name] = value
else:
self._current[field.name] = field.value_to_string(obj)

M2M with self throught int. table, how to access related items?

2011-08-16 Thread Yaşar Arabacı

Hi,

I have tried to sent this e-mail before, but I guess it didn't make its way
to the groups so I am trying to resent it, if this is a double post, I am
sorry. I am having trouble understanding m2m relation to self with a
intermediary table. Here is my table setup stripped:

   class Post(models.Model):

   relevancy =
models.ManyToManyField("self",
through="Traffic",symmetrical=False,related_name="relevant",blank=True)

   class Traffic(models.Model):
   tfrom = models.ForeignKey(Post,related_name="tfrom")
   tto = models.ForeignKey(Post,related_name="tto")
   count = models.PositiveIntegerField(default=0)

This is to be a simple visitor tendency tool, which I keep records of
which link clicked on which post. I am confused about, getting related
items. For example, given a post, how to get set of posts which have
traffic from the post (post.tfrom_set ? ), or how to get post with a
max "count" which is trafficked to the post
( post.tto_set.max("count") ? ) etc.

And also, what is the recommended way of getting, for example, given a post,
which is the post with max "count" value from this post. Like, get a list of
traffics where tfrom is given post, and get a Traffic object with max
"count" and get tto post of that traffic.

PS: English is not my main language. Sorry if I wasn't clear

Re: For loop problem in template..Is this correct

2011-08-16 Thread victorkendy

Hi

The for tag iterates over the elements of the list you are using so
your code should be

$(function() {
var data = [];
var i = something();
   {% for x in content %}
data[i] =
{
roll_no: {{x.roll_no}},
cell_no: {{x.cell_no}},
nationality:{{x.nationality}},
e_mail:{{x.e_mail}}
};
{% endfor %}

grid = new Slick.Grid("#myGrid", data, columns, options);

$("#myGrid").show();
})

Re: search with a optional value

2011-08-16 Thread Nan


Filters can be applied in multiple statements, and querysets are
evaluated lazily, so the following would work and would only run a
single query, when you finally output or otherwise check the contents
of the results variable:

def get_results(...):
...
results =
MyThing.objects.filter(required_field=somevalue).filter(other_required_field=othervalue)
if optional_value_submitted:
results = results.filter(optional_field=optional_value)
if other_optional_value:
results =
results.filter(other_optional_field=other_optional_value)
return results

Have you tried:

class Post(models.Model):
  ...
  def posts_with_traffic_from_here(self):
return Post.objects.filter(tto__tfrom=self)

Re: Json serialization help

2011-08-16 Thread Andre Terra

Thank you a lot for this snippet!

I've wondered about how to export objects to excel in a "more natural way"
and this seems to be a great approach, considering all the different
gotchas.

Thank you for taking the time to write this.. I've been postponing this
little bit of research for the longest time.


Cheers,

Re: How to Layout a Django Application?

2011-08-16 Thread Andre Terra

There are no particular layouts, but sometimes writing an inclusion tag[1]
can help with abstracting some of the logic from the template (especially in
the case of side columns that can vary based on context).

What I usually do:

Write a base.html file with some "default" data, including dummy content
text wrapped around something like a context block, eg.

{% block content %}
  No content yet.
{% endblock %}

{% extends 'base.html' %}

{% block content %}
  My content
{% endbock %}

I also have blocks for javascript, styles and extrahead, which usually are
called with {{ block.super }} in a specific template, so that I can append
more scripts to a section of the site rather than having to rewrite the
entire block.

Let us know if you need more help!

Cheers,
AT

I highly recommend Datatable... It's not to hard to do either.

Thanks .. the "using" kw hadn't occurred to me but I don't know of any
others. I'm happy now. I figure the force_* kwargs were probably the
only ones then and it wasn't too difficult for example code to mention
them. I prefer the *args, **kwargs version anyway. It hides the gory
detail from me.

Cheers

Mike

By the way, is there any other kwarg for save?

2011/8/16 Mike Dewhirst >

When using save() in a model, what is the difference between ...

save(self, force_insert=False, force_update=False) or
save(self, force_insert=False, force_update=False, **kwargs)
# whatever
super(Xyz, self).save(force_insert, force_update) or
super(Xyz, self).save(force_insert, force_update, **kwargs)

and

save(self, *arg, **kwargs)
# whatever
super(Xyz, self).save(*args, **kwargs)

I see the former in a fair bit of django example code around the
place and the latter in the docs here

https://docs.djangoproject.com/en/dev/topics/db/models/#overriding-predefined-model-methods

Thanks for any insights
