Django (cache?) make some mistake with formset generated class

[Bastien Sevajol]

Hello, i don't know if it's a django or python problem. But i correct a 
strange bug and would know why my code was bugging and if it was django, 
python, or me. The situation (and solution) is exposed 
herebut
 i reproduce it here:

I've two page, each of one display a form and a formset. They have same 
code logic:

*views*

> from django.forms.models import inlineformset_factoryfrom 
> djStock.stock.models import MyAModelfrom djStock.stock.forms.MyAModelForm 
> import MyAModelFormfrom djStock.stock.models import MyBModelfrom 
> djStock.stock.forms.MyBModelForm import MyBModelForm
> def a_create(request):
>
>   form = MyAModelForm()
>   formset_factory = inlineformset_factory(MyAModel, MyAModel.things.through)
>   formset = formset_factory()
>   [...]
> def b_create(request):
>
>   form = MyBModelForm()
>   formset_factory = inlineformset_factory(MyBModel, MyBModel.things.through)
>   formset = formset_factory()
>   [...]
>
> (With this code, all work fine) So i made refactoring and write some class 
(i removed unecessary code for exemple):

*ModelFormsetManager*

> from django.forms.models import inlineformset_factory
> class ModelFormsetManager(object):
>
>   form = None
>   formsets = {}
>
>   def initialize_formset(self, name, entity, related_entity):
> self.formsets[name] = inlineformset_factory(entity, related_entity)
>
> # for debug at the end of question
> print self.formsets[name]
>
>   def __init__(self, request, form_class):
> if request.method == 'POST':
>   [...]
> else:
>   self.form = form_class()
>   for formset_name, formset in self.formsets.iteritems():
>
> # for debug at the end of question
> print formset
>
> self.formsets[formset_name] = formset()
>
> *
*

*MyAModelManager*

> from ..models import MyAModelfrom ..forms.MyAModelForm import 
> MyAModelFormfrom djStock.stock.managers.ModelFormsetManager import 
> ModelFormsetManager
> class MyAModelManager(ModelFormsetManager):
>
>   def __init__(self, request):
> self.initialize_formset('things', MyAModel, MyAModel.things.through)
> super(MyAModelManager, self).__init__(request, MyAModelForm)
>
> *MyBModelManager*

> from ..models import MyBModelfrom ..forms.MyBModelForm import 
> MyBModelFormfrom djStock.stock.managers.ModelFormsetManager import 
> ModelFormsetManager
> class MyBModelManager(ModelFormsetManager):
>
>   def __init__(self, request):
> self.initialize_formset('things', MyBModel, MyBModel.references.through
> super(MyBModelManager, self).__init__(request, MyBModelForm)
>
>
With this refactoring my views look like:

> def a_create(request):
>   a_manager = MyAModelManager(request=request)
>   [...]
> def b_create(request):
>   b_manager = MyBModelManager(request=request)
>   [...]
>
>  

Okay, now the strange bug (keep in mind one thing: actions order is 
important): 

   - When i load *a_create* view, all is displayed correctly (reloading 
   page to). 

Prints displays that:

>  'django.forms.formsets.MyAModelThingFormFormSet'>
>
>
   - I load *b_create* view, an error raised.

Prints displays that:

>  'django.forms.formsets.MyBModelThingFormFormSet'>
>
>
And error is:

> File

> *Important note*: At "formset()" django is trying to call My 
> *A*ModelThingFormFormSet whereas My 
*B* ModelThingFormFormSet (print confirm it showing 
MyBModelThingFormFormSet). That's one of strange point.

   - 
   
   If i reload *b_create* view, same error. If i reload *a_create* view 
   it's always working.
   - 
   
   I turn off *python manage.py runserver |...]* and run it again
   - 
   
   I load *b_create* view (previously rasing error), now it's *working*.
   
Prints displays that:

>  'django.forms.formsets.MyBModelThingFormFormSet'>
>
>
   - I load *a_create* view (previously working), now it is *not* working.

Using the periodic request client-side is what is mostly done.

My question was not clear enough,
Let's admit i have this template page :

/{% for elem in data %}//
////
//{{ elem.datetime }}//
//{{ elem.name <http://elem.name>
}} ://
//{{ elem.text }}//
////
//{% endfor %}//
//Text : /

and this view.py :

/def getchat(request)://
//template = loader.get_template('chat.html')//
//context  = RequestContext(request, { 'data': lines
})//# lines is an array with lines
//response = {'html' : template.render(context)}//
//return HttpResponse(json.dumps(response),
mimetype='application/json')/

and this javascript :

/function getchat()//
//{ //
//$.post('/getchat')//.done(function(data, textStatus,
jqXHR) //
//{//
//$("#chat").html(data["html"])//
//})//
//}

/Then whenever I call getchat() in javascript, the chat is
reloaded with all the old lines, this point is ok, but
 field is reseted too, which mean that if user was
typing, the content is erased.
I would say the solution is to create a second function in
view /getchatcontent/ that will send only the content so I do
not
update the whole thing. Do you think it is the right way ?

Thank you for your answer



There is nothing more in chat.html
there is a base.html template that contains

///
//{% load staticfiles %}//






//post//
///


appchat.js


/$(document).ready(function()//
//{//
//$("#addline").click(function()//
//{//
//addline($("#chatname")[0].value,
$("#chatinput")[0].value);//
//$("#chatinput")[0].value = "" //
//})//
//setInterval(function() { getchat() }, 1000);//
//})//
//
//function addline(name, text)//

//$.post('/addline', {"name":name, "text":text})//

//   $.post('/getchat')/
/

Now you have everything, does this seems the right way to do what
I want to achieve with django or is there a better way ?

html templates and dynamic loading

[Bastien Amiel]

Hi list,

I'm testing Django for a few days now and I have 2 questions.

I created for my tests a simple chat integrated in a base page (one 
template for the main page, and one for the chat).


I need to update the chat when an event come but :

1.
If I update my chat sub page, inputs are reset (seems logic since html 
is recreated).

Then what would be the good / best method to update only the chat content ?
(I have 2 ideas but they don't seems very Django'ic)

2.
For now, I update the content every XX ms with a periodic request client 
side.
Would it be possible / preferable to have a push from server when new 
data comes or is there a better way to update this kind of content ?

Re: Is it secure to have IDs show up in URLs?

[Bastien]

Sorry maybe my post was not very clear, I am talking about public content 
here, that should be accessed by anyone, even anonymous users not logged in.
For instance if we talk about photos, publicly available, the url would 
look something like /photos/1, /photos/2  1 and 2 being the pk of the 
object in the db. If someone wants to download or link to these photos in a 
totally uncontrollable way (without using an API), with that system we are 
making it very easy to do mass content leakage. I don't want to promote 
security by obscurity here, just want to know what people in the group 
think about it and what solutions can be implemented, or if it is relevant 
at all.

The idea of slug could do the trick, but wouldn't it require some sort of 
date or title or a combination of both in the url? Not the most convenient 
in this case.

Is it secure to have IDs show up in URLs?

[Bastien]

I am concerned about seeing the IDs of objects appearing in the URL and in 
a totally predictable manner. It is very convenient and clean to do all 
sorts of things but can be abused very easily to retrieve all the content 
of the site, ie: photos... 
Is it a good idea to try to change this behavior? Maybe with some sort of 
middleware? Is there any project doing it already? For instance the urls in 
Instagram seem to be encoded at least.

Re: apache + mod_python + svn

[Bastien]

ok my bad, I didn't realize that the structure of the project had
changed within the directory now that it is controlled by subversion
and of course at the root of the directory there is no settings file,
instead I have to go to the ultimate revision.

apache + mod_python + svn

[Bastien]

Hi,

I know this is slightly off topic but such a common situation that I
guess somebody has already run into it.

I have just deployed my project on a remote debian server with apache
and mod_python following the documentation and it just works very
well.

Now I need to use subversion to keep updating the project so I
installed it via 'apt-get install subversion' and 'apt-get install
libapache2-svn'. That's where I made a mistake because I'm only using
svn via ssh so I did not need that apache mod.

What happened is that when installing libapache2-svn my apache config
files were modified and I was asked to restart the server and suddenly
I was granted with a mod_python error instead of my home page.

If anybody can spot what is wrong or knows what files have been
changed so I can change them back that would be of great help. Here is
the error message if is of any relevance:

MOD_PYTHON ERROR

ProcessId:  23452

Re: How to custom render a checkbox list?

[Bastien]

Thank you Jashugan,

that's the way I went too but I thought there was a cleaner method,
right now it's working properly so I'll leave it alone but I'll have a
look later to see if I can improve that.

How to custom render a checkbox list?

[Bastien]

Hi,

I have a list of checkboxes rendered automatically by django. It's a
list of the months of the year so the user can say when a shop is
opened. It works well but the design is not that great in the page so
instead of having all the checkboxes rendered as  I would like to
have the control of every checkbox the same way I can control the
fields of a form (that can be displayed as a  too but that can be
overridden).

so I have:

in my forms.py (a modelForm):
months_open = forms.MultipleChoiceField(choices = MONTH_LIST,
widget=forms.CheckboxSelectMultiple)

in my template:
{{ form.months_open }}

it is rendered as:

...

Do you think there is a way I can use something like
{{ form.months_open.month1 }} ?

thank you,
Bastien

best practice to have a list of mixed objects

[Bastien]

Hello,

I am trying to have a list of various types of objects, for example a
list mixed with users' profile, users' photo... to try to order all
these elements together by the amount of votes they received.

I use the list() function to store each query in a different variable
and then I extend() the list in only one variable.

I'm sure there's a better way to do that, if you have any idea you're
welcome to share it!

Thanks,

How to convert a unicode string into something that can call an object?

[Bastien]

Hi,

in one of my views I receive some unicode from javascript, namely I
receive a type of object and its pk. Then I do this:

object = request.POST['type'].objects.get(pk=int
(request.POST['id']))
and of course Django tells me that a unicode object has no attribute
'objects'. So how could I convert this request.POST to something
usable in this case?

thanks,

reverse url fails on existing url

[Bastien]

Hello,

I don't understand how this works, on my url without arguments I can
use the template tag {% url ... %} and it just works but as soon as I
have an argument like this one:

url(r'^users/(?P.+)/comments/$',
view=public_comments,
name='public_comments'),

and I call it via:

{% url public_comments args=user.username %}

then I get :

Caught an exception while rendering: Reverse for public_comments' with
arguments '()' and keyword arguments '{'args': u'my_name'}' not found.

anybody has an idea?

How to access a form subfield? form design?

[Bastien]

Hi,

I have a multi choice field to choose 1 or many months in checkboxes:

in forms.py:
months_open = forms.MultipleChoiceField(choices = MONTH_LIST,
widget=forms.CheckboxSelectMultiple)

then in my template I use {{ form.months_open }} to make the list
appear. Now that works but the list appears as a raw list without
style so I would like to change the order of the months but don't know
how to access them. I tried things like {{ form.months_open.1 }} or
{{ form.months_open[0] }} , I tried a for loop to get what's inside
but there's nothing I can do.

Anybody can tell me how this works?
Thanks.

passing variables to other views / initial function executed before every views

[Bastien]

Hi,

I need to use some kind of box (thickbox or other) popping up in front
of any page that a user is redirected to after successfully
registering a new account. The user gets redirected to the page she
initially opened before being sent to the registration form. So it
could be any page on the site. So I need a function that catches a
messages on every page. What I did is putting a reference to that
message in the base template that is inherited everywhere as such:
{{ pop_up_message }}. If there is nothing sent to that variable then
nothing happens and the page loads without popping anything. If there
is something in that variable then the corresponding pop_up box is
called via javascript.

Now it gives me 2 problems.

First, the variable {{ pop_up_message }} can only be filled if I
reload the same page and set it in the context. For example in the
registration process, if the form doesn't validate at the time of
sending it via POST the variable is set to display an error pop up
message and the template reloads with that message filled. But if the
registration process validates then a redirect occurs and I am unable
to set this variable in the context or pass it to the other views. Is
there a way to do that? right now I pass this message in the URL and
the javascript catches it just the same way but it's very ugly and I'm
sure there's another way.

Second, the person who wrote the javascript part of that system tells
me the part where we catch the message to know if a pop up box should
appear or not should be made with Django and not javascript. He tells
me there is a way to write a function that would be executed before
every views to catch this message without having to rewrite every
single view. It sounds really strange and not very Djangoish. Does
such a function exist? Doesn't catching a message on every page is
javascripts' job?

thanks for your light,
Bastien

Where should I do post form data processing?

[Bastien]

Hi,

I have a form where the user chooses her activity and then I
automatically fill the category field in the database according to her
activity. My question is where should live the code that do that? I
want it to be triggered once the user hits the submit button of the
form, I take the activity of the user, check in which category it is
and set the category field.

I couldn't find a place for that code, in the forms.py the
clean_category(self): is triggered at the right moment but it's not
intended to do that, is it? I tried but it only works when there is
actually a category entered. If not, I get a 'local variable
'category' referenced before assignment'. May be it's better to use
signals here?

Migrating (importing) SQL dump for one model

[Bastien]

Hi,

I have a running Django project with users, and a profile app for the
users to fill in info on their profile. This model is quite simple
with only a few fields, I want to replace it. I have a preexisting
database dump that contains data about existing users of a different
proforject with different fields that I'd like to import and replace
the existing Django model with.

The database I'm using is PostgreSQL and the database dump I'd like to
import is also PostgreSQL. Is there a simple way to do that? Is there
a tool to import an SQL dump directly into Django and that creates the
model? Or is there a more complex way to do it?

prepopulate file fields in forms after validation errors

[Bastien]

Hi,

When I have some validation errors in my forms they automatically get
reloaded after POST with all the fields already filled with what the
user already introduced before POST and she only has to change
whatever was wrong in the first place. But for files or images, the
path disappears and the user has to choose again which image she wants
to upload. I'd like these fields to appear populated along the others.

I thought sending form = Form(request.POST, request.FILES) to the
template was enough. Is there something I missed or do these fields
need to be populated in another way?

Global date format in fields

[Bastien]

Hi,

I needed to change the date format the user sees in a field and I used
'input_formats'. But I was wondering if there was a setting to change
it for the whole project, kind of a locale for dates. I tried to add
DATE_FORMAT / DATETIME_FORMAT to the settings file but it did not
change the behavior of the DateFields or DateTimeFields of my forms.

Thanks,
Bastien

i18n of words that switch place in a sentence

[Bastien]

Hi,

I'm sure this is in the doc but I can't find it. Is there a way to
change a word's place in a sentence according to the language setting?

What I need is to translate the term 'ago' from english to a few other
languages that place it in front of the time, an example will explain
it better:

english : 'user x commented 18 minutes ago' would translate to spanish
as :
'usuario x ha comentado *hace* 18 minutos'

and of course I would like to keep using the '18 minutes' part as a
variable so I can't just translate the whole sentence.

anyone?

Re: autofilling select boxes

[Bastien]

Hi,

I have just done it, using jquery, and I'm also new to this but it was
very easy. The logic I used is as follow:
I had a preexisting view where a user selects various criteria to add
to a blog entry like theme, geographical zone, tags... a jquery script
tracks the user inputs and for each change sends a POST to a view that
I wrote to search for related items that returns back a json list that
jquery reads to populate an html select multiple with the blog
entries' id in the value so when the user saves the blog entry, it
passes all the info as POST again to another view including the id of
0 or more other blog entries that might be related and have been
selected by the user.

I hope it's understandable and helps,
Bastien

restrict choice of recursive many to many relation

[Bastien]

Hi,

This is quite new to me, I have done a recursive (self) many to many
relation between blog entries so they can be linked together if the
user thinks they are semantically related. It works but I would like
to restrict the choices I can see in the admin list box: right now I
can see every blog entry but I would like to see only the blog entries
that belong to a given category. Can I refine the query?

That's what I have for now:
related_entries  = models.ManyToManyField('self', blank=True,
symmetrical=False, related_name='original_entries')

Thanks,
Bastien

count the number of times an object / class has been instantiated

Hi,

Just for curiosity, anyone knows about a way to count how many times
an object or a class has been instantiated? I could add a simple
counter as a method of the class but what would trigger it?

Login redirect url truncated

[Bastien]

Hi,

I'm trying to get Django to do the following:

A user must be logged in to comment on a content. If the user is not
logged in then I provide a link to the login page and use the 'next'
function to take her back to the content page where the comment box
will be waiting for her to fill it.

It almost works, the only thing is that the comment box can be quite
far away down the page if there are lots of comments and I would like
to go to it directly adding a '#comment_form' at the end the 'next'
url. That's what I do, I call a url that looks like this:
http://mysite.com/accounts/login/?next=/content/#comment_form but the
url returned by the login is a stripped down version that doesn't
contain the trailing part with the '#comment_form'.

Any idea on what I missed?

thanks,
Bastien

How to get request.user inside a model method?

The last thread about that is quite old, I was wondering if there is

I wrote a method in a model that requires the current user and I use
this method in a template so I guess I can't pass any argument, can I?

You're right Dougal, I *should* do that I have various apps already

Models Aliases

[Bastien]

Hi,

I searched the doc but couldn't find anything about this: I have a
model for a blog entry that contains a foreign key to user and is
named author. But that would be really convenient for me if the object
would respond to the keyword 'user' as well: entry.user doesn't exist
in the model but I would like it to return what entry.author usually
returns, just like an alias. Does anything like that exists in Django?
is it considered good practice? I could just use the author key or
rename it to user but what happens is that I have various applications
that already work with either object.user or object.author and I don't
want to rewrite them all. Thanks.

timesince template tag filter format

[Bastien]

Hi,

I'm using the timesince filter in a template where I print a list of
users along with some info about these users. Among this info I print
the user's age which I get from the user's birthdate and I return the
result of {{ user.get_profile.birthdate|timesince }} to get the age.
Everything works fine but the format returned is of the type 'year,
month' and I just want to print the year. I tried to format this with |
date or with |time or to find some doc about this but I can't get
nowhere.

Anybody has an idea? Thanks!

[Bastien]

Hi,

I'm trying to retrieve a list of users belonging  to a given group but
don't understand how to do it. It must be a sort of many to many query
but I can't get it to work.

I would like to do something like this:

basic_users_list = User.objects.filter(groups__in=Group.objects.get
(name='basic'))

but django tells me that:

'Group' object is not iterable

If there is another way to do some actions on a given group then I
would be as happy.

thanks for your guidance.

Re: Process multiple html forms in the same view

[Bastien]

Thank you Karen, that's exactly what I need "To give each Form its own
namespace".

Process multiple html forms in the same view

[Bastien]

I have a classic user profile page where the user fills a form with
various field about her profile (name, address, about me...). On the
same page I have another form that is very similar to a blog post
entry (title, body...) that represents a message that the user can
optionaly fill if she wants to. I can only have one submit button for
the whole page and thus the 2 forms. They both submit the POST data to
the same URL (user_ profile) and in the view I process both forms.
Everything runs quite smoothly since the validation process
automatically uses the POST data that it needs and leaves the rest
(ie: validating user profile only uses the form values like name,
address, about me... and leaves things like title, body... for later
use). But my problem is that I have a few form fields in common in
both forms: zone (which is a list of geographical zones relevant to
the website), theme (another list) and the tags field. The view in its
current form is unabled to tell apart which one is from which form,
ie: it receives tags from both the user profile and the user optional
message and can't tell them apart. So my question is how could the
view know which POST data belongs to which form or how can I change
the form fields name like the profile tags and post tags would become
tags_profile and tags_post respectively?

Thank you very much James, I couldn't get a better answer. I will try
this right away and hopefully get back on the right path!

Re: Django-Registration help

[Bastien]

I will answer my own question since I found the answer, may be it can
help someone:

in the views add this line:
from registration.forms import RegistrationFormTermsOfService

and then in the register function change form_class from
RegistrationForm to RegistrationFormTermsOfService

in the template registration_form you can now use the {{ form.tos }}

It's only a matter of form subclassing and is explained here
(somewhere down the page):
http://docs.djangoproject.com/en/dev/ref/forms/api/#ref-forms-api

Django-Registration help

[Bastien]

Hi,

I'd like to use the available functionality "terms of service" in
Django-Registration but have no clue about how I do that. I already
have the basic thing running on my project.

thanks

Thanks Dougal, I think you're right about django-cms supporting this
feature, I'm going to dive in their code.

Localize URLs

[Bastien]

Hello Django users,

I've been scratching my head trying to find a solution to have URLs
translated in various languages. So the typical 'about' would be
translated in 'a propos' in french and whatever other languages, like
all the static content. I also need to provide the user a way to write
flatpages (and other types of dynamic content) with a unique URL so
something like 'http://www.mysite.com/news/christmas_party' would
translate to 'http://www.mysite.com/nouvelles/fete_de_noel' in french.
I think you see what I mean.

I couldn't find anything googling and although I understand the
readability argument I don't know if it's a good idea technically
speaking. Any help, point of view, documentation, already exisiting
app would be welcome.

Thanks
