Upload from mobile device using POST

[Matias Hernandez Arellano]

(sorry for my english)
(i open this thread cuase the other thread was for another question)

I have a mobile device application (iOS) and i want to upload an image to my 
django application

In my mobile application i create the POST request (and disable csrf in my 
django app) using this:

- (void)upload{
NSData *imageData = UIImageJPEGRepresentation(imageView.image,90);
NSString *urlString = @"http://190.91.43.241:8000/subir/1/;;
NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] 
init]autorelease];
[request setURL:[NSURL URLWithString:urlString]];
[request setHTTPMethod:@"POST"];

NSString *boundary = [NSString 
stringWithString:@"---14737809831466499882746641449"];
NSString *contentType=[NSString stringWithFormat:@"multipart/form-data; 
boundary=%@",boundary];
[request addValue:contentType forHTTPHeaderField:@"Content-Type"];

NSMutableData *body = [NSMutableData data];
[body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] 
dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithString:@"Content-Disposition: 
form-data; name=\"file\"; filename=\"file\"\r\n"] 
dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithString:@"Content-Type: 
application/octet-stream\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[NSData dataWithData:imageData]];
//[body appendData:[[NSString 
stringWithFormat:@"\r\n--%@--\r\n",boundary] 
dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithString:@"\r\n"] 
dataUsingEncoding:NSUTF8StringEncoding]];
// setting the body of the post to the reqeust
[request setHTTPBody:body];

// now lets make the connection to the web
NSData *returnData = [NSURLConnection sendSynchronousRequest:request 
returningResponse:nil error:nil];
NSString *returnString = [[NSString alloc] initWithData:returnData 
encoding:NSUTF8StringEncoding];
NSLog(@"%@",returnString);

}

And in my Djago app:
def upload_image(request):
if request.method == 'POST':
return request.FILES['file']
return "NO imagen subida"

def subir(request,imagen):
try:
#some functions ..
result =  upload_image(request)
return HttpResponse(result)
except Thrift.TException, tx:
print '%s' % (tx.message)


but i have a error 500 and if i see the logs i have this:
Exception Type: MultiValueDictKeyError
Exception Value:
"Key 'file' not found in "

Any idea?

thanks in advance..

Re: Upload image using GET

[Matias Hernandez Arellano]

Thrift: http://incubator.apache.org/thrift/

And if it's not possible use GET to pass the image data to the django 
application..
how can i pass de data from a mobile application (without user actions like a 
web form) to the django application, and upload, or copy de data into a new 
image??

Thanks in advance

Re: pyfacebook @facebook.require_login() not working

[Matias Aguirre]

I don't have the solution for your issue, didn't used pyfacebook, yet. But if
you are looking to register users using Facebook OAuth, then django-social-auth
may fit your needs:

http://github.com/omab/django-social-auth/

Then you can use any other Facebook API around to access users content and it
integrates with django auth system easily.

Also, not related with your work, but I'm glad to announce that it gained
Google OAuth2 support recently :-)

Matías

Re: acces to dict

[Matias Aguirre]

Hi

The problem is that django template system tries __getkey__ first and as you
are using a defaultdict get key call is creating a new entry with key "items"
and empty list as value.

Try passing dict(prod_pool) to your template.

Matías

Re: how can I filter related (foreign key) objects?

[Matias Aguirre]

Just refer to the field name, you don't need the class:

prev = self.bbb_set.filter(date__lt=date)

Take a look to field lookup rules:

So, it's a POST with an "action" fiend and a "data" field that looks like

Did you tried un-encoding the JSON, like this:

from django.utils.simplejson import simplejson

data = simplejson.loads(request.POST['data'])
id = data['id']

Re: django facebook authentication

[Matias Aguirre]

Hi,

Is your request.get_host() the same defined in Facebook app settings? (Web site
section if I can recall correctly), facebook doesn't accept 127.0.0.1 as
redirect url and might not accept localhost too.

Check social_auth/backends/facebook.py on 
https://github.com/omab/django-social-auth
for an example.

Matías

The '?' should be quoted as '%3F' (urllib.urlquote('?')) or it will be treated

Re: Too many items in my drowndown list

Yes, it's possible, define them in in your inline class.

Re: Need HELP urgently

[Matias Aguirre]

Don't see the need to use an ajax solution when a simple raw field makes the
work properly. Don't get me wrong, it's good to have several options, just that
I don't see the need.

Re: Help optimising database calls

[Matias Aguirre]

Try to reduce the queries on your view, select_related won't help a lot if
using Thread model, try to collect Pun values on your view first and group them
by thread, itertools.groupby could be handy in this case. Try something like:

threads = Thread.objects.select_related('user').filter(...)
thread_ids = [th.id for th in threads]
Pun.objects.select_related('thread', 'author').filter(thread__in=thread_ids)

Then group Pun by thread and use that on your template.

Makes sense?

Matías

Re: Need HELP urgently

[Matias Aguirre]

The given answers are correct, that's your issue without doubt, create an admin
class for your Priority model and setup a raw_id_field[1]:

class PriorityOptions(admin.ModelAdmin):
raw_id_fields = ('entry',)
register(Priority, PriorityOptions)

Re: GoFlow - anybody out there used it?

[Matias]

El 06/09/10 14:23, Steve Boyle escribió:

Hi,

I've been writing an application that requires a workflow component
and rather than build one from scratch looked around to see what was
already out there.

One app that was mentioned a number of times was "GoFlow" which
apparently is based on "OpenFlow" a Zope product.

It feels as though the project has died judging by the activity /
commits etc, and unfortunately my impression is that there is a *lot*
of tidy up required on the code&  docs.

Has anybody else actually used this project, and if so what are your
thoughts?

It might save me investing a load of time in something that could have
been better spent writing something from scratch.

Many thanks


Steve



Did you give a look to ProcessMaker? At the time I had to implement a 
workflow solution, processmaker and its API did the job for us.

filter users by full name

[Matias]

Hi,

What is the recommended way to get all the users whose full_name matches 
a given string?


I need to do something like:

User.objects.filter(get_full_name="John Test")

But that doesn't seem to work.

Is list comprehensions the only way to go?

[Offtopic] Design introduction

[Matias]

Sorry for this completely offtopic question.

I'm a systems administrator with programming experience (mostly python 
and C) and I love web applications design/programming and I'm pretty 
good with html, javascript, css, etc... but I have a really weak point 
when it comes to "images" desing. I mean, I'd love to learn how to do 
images like this:

http://www.freecsstemplates.org/previews/solutions/images/img01.gif

(from the template http://www.freecsstemplates.org/preview/solutions/)

I understand the basics, and I use quite frequently Gimp, but this is 
not like coding, when you code, most of the times it is easy to 
understand what is happenning (except if the code you are reading is 
perl :-P ) and thus, you can learn but I still can't "read" images I 
see out there, so, I guess there should be any learning path for this 
also or maybe is that just the creative half of my brain is missing.


Would you recommend any book? any website? or some other way to learn to 
do "nice 3d looking menus, buttons"..etc?


Thanks for your help, and sorry for the offtopic, but I didn't find a 
better place to ask this. (didn't look for a lot also...)



Thanks!

register model on different App

Is there any way to register a model on a different app so that on the

I've created a custom model, that I'd like to be shown on the "Auth" box 
instead of the default one (a box with my app's name).

ContentType and __unicode__ description

[Matias]

Hi,

I have a model like:

Class MyModel(models.Model):
content = content.ForeignKey(ContentType)

And in the admin interface I have a dropdown box showing all the content 
types I have. Works perfect.


The problem is that on that dropdown box, I have for each item there the 
"name" attribute of the content type. Is there any way to override this 
behaviour in order to get something like "name (app_name/model)" as the 
description so that the user can know to which application the model 
belongs to?




Thanks a lot.

When you create a signal you can optionally assign a model to listen
too. Not doing that means it is called for all models.

Register signal on all objects

[Matias]

Is there any recommended way to attach a post_save signal to ALL models?

The best way I'm thinking of is maybe by using the ContentType class to 
get a list of all models and iterate over them registering the signal, 
but I'm not sure if this is the best way to do it...


Any comment appreciated... Thanks!!

Re: apache2+mod_wsgi: 403 Forbidden

[Matias]

I think you missed the allow directive in your apache conf.

Example from [1]

Alias /media/ /usr/local/django/mysite/media/


Order deny,allow
Allow from all


WSGIScriptAlias / /usr/local/django/mysite/apache/django.wsgi


Order deny,allow
Allow from all


[1] http://code.google.com/p/modwsgi/wiki/IntegrationWithDjango

Re: Outputing an integer value in a template, but with some calculation done on it

[Matias]

If you're using Pagination
http://docs.djangoproject.com/en/dev/topics/pagination/ you can get the
previous and next pages like this:
{{ current_page.previous_page_number }}

If not, check it out. It's a simple way to manage pagination issues.

Re: pyfacebook, No module named facebook.djangofb...

[Matias]

Where did you get the files?
if you go to the pyfacebook at google
http://code.google.com/p/pyfacebook/the project is now hosted in
github.
So if you downloaded from google it may be outdated.
The installation is much more simpler than what the tutorial says, so i
recommend to download from http://github.com/sciyoshi/pyfacebook/tree/master

How to tell if a fields was modified

[Matias]

Hi,

How can I tell which model fields have been modified (this is, the 
difference between the Model instance and the data originally retrieved 
from the database) from inside the model's save() method?


Any idea?

Thanks a lot!

Replying to myself, here is the solution:



class LimitedCustomUserAdmin(UserAdmin):
 inlines = [ProfileAdmin]
 form = forms.CustomUserChangeForm
 fieldsets = (
 (None, {'fields': ('username', 'password')}),
 ('Personal info', {'fields': ('first_name', 'last_name', 
'email')}),
 ('Permissions', {'fields': ('is_staff', 'is_active', 
'is_superuser')}),
 ('Important dates', {'fields': ('last_login', 'date_joined')}),
 ('Groups', {'fields': ('groups',)}),
 )



class CustomUserAdmin(LimitedCustomUserAdmin):
 fieldsets = (
 (None, {'fields': ('username', 'password')}),
 ('Personal info', {'fields': ('first_name', 'last_name', 
'email')}),
 ('Permissions', {'fields': ('is_staff', 'is_active', 
'is_superuser', 'user_permissions')}),
 ('Important dates', {'fields': ('last_login', 'date_joined')}),
 ('Groups', {'fields': ('groups',)}),
 )
 def __init__(self,*args,**kwargs):
 CustomUserAdmin.limited_user_admin = 
LimitedCustomUserAdmin(*args,**kwargs)
 return super(CustomUserAdmin,self).__init__(*args,**kwargs)

 def __call__(self, *args, **kwargs):
 if get_current_user().is_superuser:
 return super(CustomUserAdmin, self).__call__(*args, **kwargs)
 else:
 return CustomUserAdmin.limited_user_admin(*args,**kwargs)



This way, super_users can view/edit the fields defined in 
CustomUserAdmin and non super_users can view/edit the fields on 
LimitedCustomUserAdmin.


Note: You've to register only CustomUserAdmin with the User model.

Django is compatible with all javascript frameworks. Personally, I 
prefer JQuery.

Auto populate ModelAdmin

[Matias Surdi]

I've noticed that on the admin interface, if a model has for example a 
"name" attribute, if I access to the add form with an url like this:

http://localhost:8000/admin/mymodel/add?name=something

The name field is prepopulated with the parameter value.

Is this behaviour documented somewhere?

Is it possible to prepopulate this way inlines for the model?


Thanks a lot.

django way to pass parameters to templates

[Matias Surdi]

Which is the correct or recommended way to accomplish what is described 
in the following url with django?

http://www.djangosnippets.org/snippets/11/



My question is, if I have a template like this:

{% for i in args %}{{ i }}{% endfor %}
{{ title }}
{{ name }}
args
{{ args }}
kwargs
{{ kwargs }}


I'd like to "include" it from several places but with different values 
for the variables each time.


Thanks a lot.

Re: Dynamic Form？[Newbie]

[Matias Surdi]

Hi Andrews,

Look at this:

http://www.b-list.org/weblog/2008/nov/09/dynamic-forms/

This helped me a lot a couple months ago when I had to do some dynamic 
forms. Those forms where generated from data entered by the user in a 
previous step.


It can be a bit "messy" if you don't take care, but works.

Re: Announcing Django Noob Group

[Matias Surdi]

I don't think it is really needed.

I think this list is perfectly OK for newbies and advanced users.There 
is not a clear line defining when you are a newbie and when you are an 
average user as well.

Now, we must search two archives instead of just a centralized one.

Problems with authentication login/logout

[Matias Surdi]

I've followed the documentation on users authentication and it's working 
fine except for one thing.

When a user logs out from the public views, it is also logged out from 
the admin site and when the user logs in in the public view, if it has 
staff permission it can access the admin site.So far, so good. *The 
problem is that when the user logs in directly to the admin interface is 
not being logged in into the public views*.

What could be happening here?

About django validation system

[Matias Surdi]

Shouldn't validation be defined in the modell instead of the forms?


Suppose I've a Model wich has some restrictions on the value a field can 
get, and then I've a custom form for this model for the admin interface 
and two other forms for the public interface.

Does this mean that I've to define my validation rules three times?

What is the logic behind  this?

Where is the correct place to code these custom validation rules in this 
scenario?

Should I post this message to django-devel?

What is the meaning of life? (well, you can ignore this last one :-) )

Thank you very much.

forms.BooleanField(widget=forms.widgets.HiddenInput,required=False)
 class Meta:
 model = IPAddress


class IPAddress(BaseModel):

Despite the widget of notification_sent is set to HiddenInput, the label

Yes, maybe it's just a problem with sqlite, which is te backend I'm 
using.I'll try with mysql later.

Is this a bug? should it be reported as a ticket?

Sorry, these quotes are a typo, the running code doesn't have them.

I've also tried with:

cursor.execute("select * from table where 
field=:value",{'value':'something'})

And I got the error:
"Type error: not all arguments converted during string formatting"


The curious thing here, is that the above query works perfect running it 
directly through sqlite3.

Raw SQL parameters

[Matias Surdi]

Hi,


I'm trying to run a sql query with parameters taken from a dict, here is 
the relevant part of the code:
query = "select * from table where name='%(name)s'"
parameters = {'name':'valueofname'}
 cursor = connection.cursor()
 data = cursor.execute(query,parameters)


The error I get is:

TypeError: format requires a mapping


But, as far as I know (from PEP249) this should be possible.
Basically, what I need, is to pass the parameters values in a dict, and 
not as a list or tuple as is shown in django docs.

Which is the correct way to accomplish this?

Thanks a lot.

hmm... Not really... from your point of view, think about this:  I want 
to edit the children from the parent admin view, and *not* assign 
parents to children from children's admin view

Do you see? the relation is the same, but from the other side.

I think I'm going to need a custom field/widget for this.

Thanks for your help.

ModelMultipleChoiceField in admin interface

[Matias Surdi]

Hi,

I've two models related by a ForeignKey field.

I'd like to have the possibility of adding child objects (side "One" of 
the relation) from the admin interface of the parent ("Many" side of the 
relation).

Example:

class Child(models.Model):
name = models.CharField(max_length=10)

class Parent(models.Model):
   name = models.CharField(max_length=10)
   childs = models.ForeignKey(Child)


In this example, a dropdown is shown on the admin that let's me choose 
just one child or create another if the one I need doesn't exist.

The point is, how can I have a list that lets me choose more than one 
child and create them as needed?

This is not a Many to Many relation, because every child belongs just to 
one parent, but the widget I need is like the one from that kind of 
relation in the admin interface (ie: Groups selection in the User edit 
admin view).


Thanks you very much.

Re: Iterate over model database fields

[Matias Surdi]

Great!!

I think that the _meta attribute will be enough. I think that if I 
define a method on the base model of all my models something like 
get_fields() it could then return a list of the fields by accessing 
self._meta.fields, and this get_fields should be accessible from 
templates,shouldn't it?.

Thanks for your help :-)

Iterate over model database fields

[Matias Surdi]

Is there any way to iterate over all the fields in a model instance on a 
template?

I'd like to have a "default" template which iterates over whatever model 
yo give it and prints all its field on a table.


Any help will be appreciated.

Run sql query as read only user

[Matias Surdi]

Hi,

For some reports, I need to allow the users to enter a sql query.It is 
required for this query (a sql SELECT) to be run as a read only database 
user.


Any idea how to implement this with django?


Thank you very much.

custom field value representation

[Matias Surdi]

Hi,

Suppose I have the following model:

class Document(BaseModel):
 name = models.CharField(max_length=150,blank=True)
 description = models.TextField(blank=True)
 file = 
Models.FileField(upload_to="data/documentation/document/%Y/%m/%d",blank=True)


And suppose I've a model I created through the admin interface and 
uploaded a file named "document1.pdf"

Then, when modifying this database entry (in admin->change_form) I see 
the previous value as data/documentation/document/2009/01/03/document1.pdf"

Is there any way to get this value shown as just "document1.pdf" without 
the relative path?.. What i want, is to hide to the end user the 
filesystem location of the uploaded file.

I've accomplished this in the change_list by defining a custom method on 
the model that returns just the file name.

Thank you very much.

saving unicode data in file

[Matias Surdi]

Hi, I'm trying to save on a FileField some generated data (a text file 
obtained from a template):

The relevant code is:

 out = Template(open("/path/to/template").read())
 context = Context({})
 if request.POST["name"] != "":
 name = request.POST["name"]
 else:
 name = "GeneratedDocument_%i" % obj.id
 data = out.render(context)
 obj.file.save("file",ContentFile(data))


the problem arises with ContentFile(data), if data is just a string like 
"a simple string" the everything is correct, but the actual data content 
is an unicode string, so raw binary data is saved to the resulting file 
instead of the actual text.

Simplifying, what I want is to save the output of a rendered template to 
a FileField.

Any help will be very appreciated.


Thanks a lot.

Re: login_required redirects always to LOGIN_REDIRECT_URL?

[Matias]

Hello,

You can add a hidden input named "next" where you put the value of next in
the GET variable.
Like this






Or you can change the action variable of the form to include the current GET
variables. like this





If your view that handles GET and POST aren't the same you must add the
"next" var in the action field on your own.


The latter is the best IMHO.

Hope that helps!

Regards,
Matias.

Re: login problem

[Matias]

Hello,

You should show the login if the method != "POST".
By calling render_to_response(...) it will render your template, so that is
what the view must return.

I think you want something like this:

def my_view(request):
  if request.method == "POST" :
  username = request.POST['username']
 password = request.POST['password']
 user =  authenticate(username=username, password=password)

 if user is not None:
if user.is_active:
   login(request,user)
   return render_to_response('success.html',
{'username':username})
else:
   return HttpResponse('disabled account')
 else:
return HttpResponse('invalid login')
   else:
 *return render_to_response* ('login.html', {'username': username,
'password' : password})

Regards,
Matias.

Re: login problem

[Matias]

Hello,

You should check by which method was called your view.
something like

if request.method == "POST":
#now you can use request.POST
else:
#just show the template


Hope that helps,

Matias.

Re: Question about field/widget relationship

[Matias]

Hello,

The widget kw can be either a class or an instance. You can do
xField(widget=xWidget(choices=mychoices))
Or you can create your xField with your xWidget as default widget and let
the field to accept the choices kw.

Re: exclude on ModelForm doesn't work

[Matias]

Hi,

How do you register the model in the admin site?
You should register your model using a ModelAdmin subclass.

Here is some docs that may help you
http://docs.djangoproject.com/en/dev/ref/contrib/admin/

The ModelForms are ment to be used in your applications rather than the
admin site.

Hope that helps

Best way to modify admin css

[Matias Surdi]

Hi,

Which is the best/recommended way to modify admin css ?

I know I can copy the admin templates to my templates dir and modify 
them as I wish, but that could be a problem in the future if these 
templates are updated in a new version and I want to switch to that version.

Thanks in advance.

I want to have on the admin interface a dropdown box and let the user 
choose one of several options.Then, depending on this selection, update

Could anyone give me some guidelines or documentation about how is the

Re: profiles not saving....just not seeing problem

[Matias]

Hello,

ModelMultipleChoiceField fields cleaned data are lists, so you are trying to
create an object with a list of ids as id. Also I think you want to retrive
the object, in that case you have to use the get function of the model
manager (e.g.  Object.objects.get(id=someid). )
If you need to get all the options of a multiple choice field, you must use
a ManyToMany relationship instead of a ForeingKey.

Regards,
Matias.

Django with non-sql database

[Matias Surdi]

Hi,

I'm trying to figure out how to use django models without an SQL-capable 
database. The database I'm trying to use are mainly simple plaint text 
configuration files.

I think the way to go is creating a custom manager. Is that correct?
Any better idea?

Thanks.

help with limit_choices_to

[Matias Surdi]

Hi.

I've the following model:

class ExamAttributeCalification(models.Model):
exam_result = models.ForeignKey(ExamResult, 
edit_inline=models.TABULAR, num_in_admin=1)
exam_attribute = 
models.ForeignKey(ExamAttribute,limit_choices_to={"exam__id":1})
 calification = models.IntegerField(core=True)


As you can see, in the last line I've a hardcoded "1". This id should be 
taken dynamically from exam_result.exam.id model attribute.

How could I accomplish this?

Thanks for your help.

Despite the typo, I'm still having the same problem.

What I want to do, is not to have a "public" download url I want to 
check user's permissions before a download is started. So, I want to 
change the behaviour of get__url so that it returns a custom view 
instead of the public url.

I think I'm isolating the problem, I think it's related to the field's

override get_file_url()

[Matias Surdi]

Hi.

I'm trying to upload files to a directory that is not under the web 
server root, for security reasons.

I wonder if is it possible to override the model's "get_FOO_url()" 
method so that It will return some form of encoded url.

I've already achieved this by defining in my model's class a 
_get_FIELD_url(self,field) method, but I'm not sure that is the correct 
way to do this.


Thanks a lot.

I think what I was looking for is this:

Could this cause any problem? Is this the correct way to do this?

newforms initial value

[Matias Surdi]

Hi.

How can I pass an initial value to a newforms form's widget?

I know that there is an "initial" parameter for widgets, but what if I 
don't know that parameter's value beforehand?

What I'm trying to do is to be able to make a request to an url and 
depending on some url parameters generate a form wich will take its 
initial values from those url parameters.

Any idea?

Thanks a lot.

Custom tag keword arguments

[Matias Surdi]

Hi,
Is it possible to pass keyword arguments to a custom inclusion tag?


example:


@register.inclusion_tag('shared/form.html')
def form(form, action="",method="POST"):
 return {"form": form,
 "action": action,
 "method": method}


I'd like to call this from a template, using something like this:

{{ form myform,method="POST"}}

What is the correct way to do this?


Thanks.
