Tou have not explained what sqlforms are or what they do, but going by the name 
alone that looks like django's modelforms: web forms autogenerated and backed 
by db models.

dhango class based views - Saving post data

[Shekar Tippur]

Hello,

I am trying to save post data and I get a error. I am trying to use enum 
field.

prefs' is an invalid keyword argument for this function

Request Method:POSTRequest URL:http://127.0.0.1:8000/setPrefs/Django 
Version:1.8.2Exception Type:TypeError

Here is my model

class UserPrefs(models.Model):

Preferences = (
('0','Likes'),
('1','Dislikes'),
('2','Shared'),
('3','Rejected'),
)
user = models.ForeignKey(AuthUser, related_name='Screens')
#user = models.ForeignKey(AuthUser)
address = models.ForeignKey(Address)
prefs = models.CharField(max_length=1,choices=Preferences)
class Meta:
#managed = False
db_table = 'user_pref'

def save(self, *args, **kwargs):
super(Screens, self).save(*args, **kwargs)


Appreciate if someone can shed some light on this.

Reuse jquery

[guettli]

I guess I am missing something.

Is there no way to load jquery only once per page?

Use case: I have two widgets which need jquery. I want to use
these widgets inside the admin interface and on custom pages.

The admin interface has its own jquery and in jquery.init.js this gets done:

var django = django || {};
django.jQuery = jQuery.noConflict(true);

Since jQuery gets removed from the namespace. This means I can't use
it in the js-files of my widgets. 

I really would like to load jquery only once per page.

Regards,
  Thomas Güttler

Why sqlite time is different from my settings.py TIME_ZONE?

[Hyunseo Yang]

I'm using Sqlite for my project database.
I need date and time in my model so i'm using this field.

date = models.DateTimeField()


On the result template (results.html), the time is correct (localtime 
or  TIME_ZONE in my settings.py)
The problem is, when i check the database on Django admin page and sqlite 
db file, it seems like my timezone setting is not applied.(so, maybe UTC)

what is the problem and how could i fix this?

I think the template's parameters are from view, so the timezone.now() is 
correct and passes the right time.
So my guess is that 'date=timezone.now()' passes to sqlite like this: 
'insert into table values (date=datetime('now'))'
and the timezone of sqlite is maybe set to UTC default. 
this is what i'm guessing. am i right? also i do not know how to set sqlite 
database timezone...

p.s On the other side, I also think when we set settings.py TIME_ZONE, 
django would manage all these things.
So don't know where to approach. Spending almost 2 days on this problem...

Re: Why sqlite time is different from my settings.py TIME_ZONE?

[Dan Tagg]

Hi Hyunseo Yang,

SQLite does not save the timezone in the database. If you pass it a
datetime with timezone encoding then it calculates the UTC time that that
time represents and stores that.

It is explained here:
https://www.sqlite.org/lang_datefunc.html

As far as I understand whatever database you are using, Django always
stores datetimes as UTC.

What version of Django are you using as timezone awareness is different for
different versions.

Graph theory ??

[Rafael E. Ferrero]

Hello everyone,

I think to do an app where i would save a directed graph.
The vertex and edges there must be dinamics.
The vertex can represent some Tag or Category... or something.
The edge who links the vertex can be N between two vertex and represent
some event or action... and let me explain here what i need to do:

Suppose you have Vertex1 and Vertex2 and are linked by edge1 from vertex1
to vertex2, edge1 have the action "Add if not exist" and mean that if the
user select the vertex1, the system, automatically add vertex2. Even
further, suppose you have a third vertex related to vertex1 by edge2 and
the action of that edge its "delete if exist" so if the user have,
previously, selected vertex3, when select vertex1, vertex3 would be deleted
by edge2.

Make a model to save the graph it's not a problem (save vertex and edges
and specify what action have every edge)... my problem its develop every
type of event or action for the edges, save that event on database and then
execute that event when needed.

Someone have a recommendation for me?
THANK YOU ALL!!!

Re: Graph theory ??

[Erik Cederstrand]

Hi Rafael,

Assuming you have a static and limited set of actions, and they can only be 
defined programmatically, I would do something like this:


class Vertex(models.Model):
 some_field = models.CharField()


class Edge(models.Model):
from = models.ForeignKey(Vertex, related_name='outgoing')
to = models.ForeignKey(Vertex, related_name='incoming')
action = models.CharField(choices=(('action1', 'action1'), ('action2', 
'action2'), ...))

def action1(self):
# Do something here
pass

def action2(self):
# Do something else here
pass

   def run_action(self):
  return getattr(self, self.action)()


When and where to call run_action() would depend on your requirements - either 
in the save() method on Edge, in a signal, or within a view.

If you were looking to define custom actions on the fly via a GUI, you would 
need to define a DSL containing the constructs you allow, create a view where 
the user can compose an AST using the constructs of the DSL, and store the 
resulting AST in the database. When you need to run the action, you would 
translate the AST to Python and run that.

You can also have a look at 
https://www.djangopackages.com/grids/g/trees-and-graphs/ 
 and see if anything 
suits your needs.

Re: Graph theory ??

[Rafael E. Ferrero]

Thanks Erik, Defining custom actions its what i try to do!! because, the
user can add some custom type of Action and he need to specify what to do
with.

With this, the user can perform his own graph and rules to control the
vertex.

For example, a Contact of the business can be a Provider or a Customer for
the business and, also, can be a Person or another Company but if is a
Company he can't be a Person... if is a Contact, and a Provider and a
Person he could be a Medic, but if is a Medic he can't be treated like a
simple Provider...
So, Contact, Provider, Customer, Person, Medic are the vertex and you need
actions to control the automation of the graph, and the actions can be
change from one implementation another.

Like you say, maybe usind DSL and AST i can execute custom actions using
Signal

THANKS A LOT!!

and now Do you think that this could be a good approach? or you suggest
something better ??

blank=True, null=True)
date_end_preview = models.DateField('Data Prevista Final', blank=True, 
null=True)
date_start = models.DateField('Data Real Inicial', blank=True, 
null=True)
date_end = models.DateField('Data Real Final', blank=True, null=True)

class Actions(models.Model):

date_start_preview = models.DateField('Data Prevista Inicial', 
blank=True)
date_end_preview = models.DateField('Data Prevista Final', blank=True)
date_start = models.DateField('Data Real Inicial', blank=True)
date_end = models.DateField('Data Real Final', blank=True)

actionplan = models.ForeignKey(Actionplan, verbose_name='Ações', 
related_name='actions')


---
and I want in admin do:

When the user create a action, the dates in actionplans update with the sum 
dates...


thx a lot...

Re: Reuse jquery

[guettli]

Hi,

we had a very strange problem with the ordering of the JS files.

the jquery.init.js from django removed the jquery from us which had 
jquery-ui loaded.

The problem is solved.

Reduce number of calls to database

[Cherie Pun]

Hi,

I am new to Django and I am performing some iteration on a queryset. When I 
use django_debug_toolbar to look at the SQL usage, I realised that Django 
is actually calling the database once in each iteration. Is there a way to 
make it call the database only once and somehow store it locally so that I 
can iterate on it?

Code:
for level_id in levels_id:
   levels.append(get_object_or_404(Level, id=level_id))


I am trying this modified code, but it seems that it's still calling the 
same number of times.

levels_dict = repr(Level.objects.values('id', 'name'))
for level_id in levels_id:
levels.append(levels_dict.get(id=level_id).get('name'))

I am trying to use this pattern in quite a few places, where I want to get 
some data from a list of objects retrieved from the database and iterate 
over them. 
I would be happy to provide any missing information.

Could anyone kindly help me out? Cheers!

Reduce number of sql calls to database

[Cherie Pun]

Hi,

I am new to Django and I am trying to reduce the number of calls to 
database as it's slowing down the app. I am performing iteration over the 
queryset and I used django_debug_toolbar to check the number of queries 
made, and the number is huge. It looks like django is making a query call 
to the db in each iteration. Is there a way to make it only send one query 
and then store the result locally and iterate over it?

Code:
for level_id in levels_id:
levels.append(get_object_or_404(Level, id=level_id))

I have been trying out this code, but it seems that the number of sql 
queries is still the same.
levels_dict = Level.objects.values('id', 'name')
for level_id in levels_id:
levels.append(levels_dict.get(id=level_id).get('name'))

I am using the same pattern in a few places to get data from each of the 
object in the queryset, is there a way to improve the performance? I am 
happy to provide any missing information. Cheers!

P.S. I tried to post just now but the post seems to be missing so I am 
trying again, hopefully I didn't post twice!

Re: Reduce number of calls to database

[Simon Charette]

Hi Cherie,

A `id__in` queryset lookup should issue a single query.

levels = Level.objects.filter(id__in=level_ids)

Cheers,
Simon

How about this:

Levels.objects.filter(id__in= levels_id)

Help needed for big django project (crm+shop+cms+autoresponder). What apps shall I build on?

[ThomasTheDjangoFan]

Hi guys,

I am planning on a bigger django project with a lot of functionality.

The thing is that I have NO experience with existing django-apps that might 
fit and definetly need your help.

Can you give me a hint which existing (and stable) django-apps I could use 
as a foundation for my project?

Those are the functions that I would like to implement (ordered by priority)
 1. *CRM* system
 -> client database
 -> ticket system (client communication including sending emails from 
backend)
 2. *Shop*
 -> calender booking system
 -> PDF billing generation
 3. email *autoresponder* system
 4. *CMS* functionality would also help

I would be really thankful if you could guide me to the right direction.
Which way shall I go?

Kind regards
Thomas

new to Django having models/views/templates question

[Chris Strasser]

Hi am plugging away at learning Django and have done well so far (thanks to 
great documentation and Stackoverflow) but I have run into a problem that i 
cant seem to figure out. 


I have a model that refers to another model that refers to another model. 

example :

Class ServiceOrder 
id -integer
   customer location = foreign key to location 

def __str__(self):
return self.stid

class Location:
   id -integer
   address -char
   customer- foreign key to customer

q= '%s %s %s %s ' %(self.addr1, self.addr2, self.city, self.country)
return unicode(q).encode('utf-8')

Class Customer
id=int
name- char
return unicode(self).encode('utf-8')

I have a template that lists the service orders view is below:


def serviceorder_list(request, status = 'Closed'):
ist = ServiceOrder.objects.filter(status = status, 
stid__lte=20239).select_related('customer_location__customer')
#stid__lte 20239 to fix database error ... i have existing data that has 
its own issues...
count = order_list.count()
context ={'list': sto_list, 'count': count}
  
return render(request, 'order/listview.html', context)


in my listview.html

{% for item  in list %}
{% if item.project %}
{{item.stid}}
{{item.project}}
{{item.customer_location.name}}  
-- 2 questions here  1) it throws an error on customer 
names that have accents etc ...  

{{item.notes}} 
 
2) i am confused about how to properly referenece the 
customer name or anything else that is not in the Service order  model. 
   
{{item.person_responsible}}
{{item.entrydate|date:'M-d-y'}}
  {{item.status}}
  {{item.billing}}  
  


I have read the docs many times and the more i read the more i know that i 
don't know ... any help would be appreciated


Thanks

Re: new to Django having models/views/templates question

Can you post the error and traceback? It sounds like you may have an
encoding issue.

Re: non DB related fiels in model to appear in a form

[Chris Strasser]

hi Reiner I think what you want to do is controlled in the view not the 
model. 

in your view do something like this:

context = {'form':form, 'infotext': "some informational text"}  
 return render(request,'form.html', context)


then in your template you can refer to it as follows:

{{form.name}}

{{ infotext}}

{{form.Ans1_OKH}} 
{{form.Ans2_OKH}} 
{{form.Ans3_OKH}} 

hope that helps ...

Re: dhango class based views - Saving post data

[James Schneider]

I just looked over your model again. Your save() override has a
super(Screens,...) reference, which doesn't match the model class.

That may explain why you are getting the invalid parameters error, since
you are probably calling the wrong save function from a different class.

I'd remove that save() override entirely.

-James

I get a error: {"prefs":["\"Likes\" is not a valid choice."]}

If I use

curl -H  "Authorization: Bearer $usertoken" -H "Content-Type:
application/json" -X POST -d '{"user":"foo1","stock":"XYZ","prefs":"1"}'
http://${endpoint}/addPrefs

I get the above trace.

James,

I have commented save in model code. I have also changed the prefs field to 
be char(20) for now.

I still get 

'prefs' is an invalid keyword argument for this function

Re: django-summernote WYSIWYG editor: mixing modelForm and model, problem with Images

[hemulin]

Hi,
not sure what I've done but I don't get the error anymore, instead I got 
nothing. No error, no image in the preview and no image after the saving 
and displaying the article.

To your questions, yes and yes. I can find the image in the server (under 
static/media/django-summernote/), and I can find the image 
in the DB.

Interestingly, while using the "load image from URL" option in the 
summernote dialog, the url is inserted well, both in the preview and in the 
displayed article ( tag with the url src in the right place in 
form.cleaned_data['text']).

Evidently the problem exists only when uploading a local image. Which leads 
me to the assumption that there is a problem with my media settings...

What I have is this:
STATIC_URL = '/static/'
MEDIA_ROOT = os.path.join(PROJECT_PATH, "static", "media")
MEDIA_URL = "media/"

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

I can access the uploaded images via 'media/' and browsing through the 
folders, so I thought it's set up well, no I'm not so sure.

Any idea what's going on here?

Wait, what does your serializer look like? I found this in the traceback:

ile "/Users//PycharmProjects///modelserializer.py" in create

  48. return Screens.objects.create(**validated_data)

Are you sure that you are referencing the right serializer and/or is the
serializer referencing the right model? I wouldn't assume that a create()
call would be made for Screens.

-James
James,

I have commented save in model code. I have also changed the prefs field to
be char(20) for now.

I still get

'prefs' is an invalid keyword argument for this function

Re: django-summernote WYSIWYG editor: mixing modelForm and model, problem with Images

[James Schneider]

Have you validated that the URL being generated in the final HTML (the
source HTML in the browser) is pointing to the right location? If not, I
would tend to agree with your assertion that the media settings need
tweaking.

Re: new to Django having models/views/templates question

[James Schneider]

Posting the actual model code will probably help.

Your template has this:

item.customer_location.name

But you specified the issue later as this:

item.customer_location.customer

The former won't work per your summarized model definitions. The Location
model has no attribute called 'name'.

The latter will work only if your __str__() function is encoding the data
correctly. The reason you are getting a recursion error is because of the
'unicode(self)' (which I'm assuming is part of your model's __str__()
definition). You need to change that to something like unicode(self.name).
I'm not even sure if the unicode() call is even necessary (haven't done a
ton of Python 3 yet).

As far as referring to the Customer name, you can do {{
item.customer_location.customer.name }}

Have you thought about tying in the customer directly to the service order?
It shouldn't be an issue to have a customer tied to both the location and
the service order. While it'll work the way you have it, your lookups will
become more complicated (and expensive from a processing perspective) since
you are forcing a lookup across multiple tables. It may not agree with your
business process, though. Just a thought.

Re: django-summernote WYSIWYG editor: mixing modelForm and model, problem with Images

[hemulin]

I'm not sure I understood your question.
If by "final HTML" you mean the rendered template which displays the 
article, then there's nothing interesting here. I'm just passing the 
article in the context to the template and in the template assigning in 
various tags the relevant content ({% article.title %}, {% article.text %}, 
etc.)

I'm more concerned (or lets say, suspicious) that even after the image 
dialog is closed (and the upload request is being processed and returned 
'200 ok', and the file is on the server) the image is not shown in the 
summernote editor.

Does the settings looks ok to you?

 (noob warning)

 I wanted to use summernote within a model but without using the default 
 modelForm.
 I ended up mixing the two like this (can't have widgets on model 
 field...):
 In models I have

 class Article(models.Model):
  """Represents a wiki article"""
  title = models.CharField(max_length=100)
  slug = models.SlugField(max_length=50, unique=True)
  text = models.TextField()
  author = models.ForeignKey(User)
  created_on = models.DateTimeField(auto_now_add=True)
  objects = models.Manager()
  tags = TaggableManager(through=TaggedArticle)

 class ArticleForm(forms.ModelForm):
  class Meta:
   model = Article
   fields = ['text']
   widgets = {
 'text': SummernoteWidget(),
   }

 After having the right display while serving the template, I attempt to 
 save the Article like this:
 in views, a part of the saving method:

 form = ArticleForm(request.POST or None)
 if form.is_valid():
 #import pdb; pdb.set_trace()
 article = Article()
 article.text = form.cleaned_data['text'] # THIS IS MY HACKISH WAY OF 
 FETCHING THE CONTENT
 article.author = request.user
 article.title = request.POST['title']
 article.save()
 if request.POST.has_key('tags'): #add relevant ones
   article_tags = request.POST.getlist('tags')
   article_tags = [tag for tag in article_tags]
   article.tags.add(*article_tags)
 return HttpResponse("Article saved successfully")

 1) I have everything configured (MEDIA_ROOT, MEDIA_URL, summernote url 
 as described in the setup)
 2) The widget is displayed well within iframe
 3) When uploading an image I get the "mime interpreted as text blah 
 blah blah" error
 4) After saving, when displaying the article, the text is displayed 
 well with all the markup but no image is displayed
 5) For every image I try to add to an article, the image appear in 
 django-summernote//.

 Finally, how would you suggest me to solve the problem and having the 
 images uploaded and displayed correctly in the resulted article text?

 Cheers.

Re: Trouble w. Setting Up Virtual Env.

[Mike Dewhirst]

Steve

If you have uninstalled and reinstalled virtualenv exactly the way the 
virtualenv docs require for Windows and you still get the same problem I 
think your environment must be blocking things.


Maybe there is a virtualenv mailing list you could join and get some 
help from virtualenv experts. I use it but I installed it some time ago 
and it just works for me.


It will be well worth your time and effort to keep trying.

Good luck

You are right. I am able to get past that issue.
The next stumbling block is with 

null value in column "address_id" violates not-null constraint
DETAIL:  Failing row contains (10, Likes, null, null).

Here is my curl

curl -H  "Authorization: Bearer $usertoken" -H "Content-Type:

How do I pass the address name so that it gets translated to an id in the

Re: django-summernote WYSIWYG editor: mixing modelForm and model, problem with Images

[James Schneider]

Sorry about that. What I meant was what do the URL's look like after the
template rendering completes (ie what does the browser see as the value for
your  tags). Since it is breaking while editing the
document, that question is now moot.

Your media settings are probably OK (however I'm smashing together paths in
my head, so I can't say for sure), but you'll need to verify that
summernote is properly generating the URL's. After uploading the photo, you
should see the 200 response for the file upload request. I then assume that
another piece of JS fires off to pull down the image that was just uploaded
so that it can be displayed in the editor. Do you immediately see another
GET request after the file upload for the image file completes? If so, does
the URL that is being requested appear correct, and if so, what is the
server response? If you are receiving a 200 response to pull down the
picture, or if you can manually copy/paste that image path in another
browser tab and pull down the picture yourself, then there is something
going on with the Summernote JS and you'll need to take that up with them.
If it is using the wrong URL, then you should check the upload settings
within Summernote (seems like there are a fair number of them), and if that
fails to bear any fruit, you'll probably need to open a request with them
on how to troubleshoot.

Given that you can see the files on the server via the browser manually,
and the uploader appears to be working correctly, I think you can narrow
down the issue to something within Summernote. I saw that you opened a
ticket on GitHub with them.

HTH,

-James

Re: Update dates in models auto

[Lachlan Musicman]

Over ride the save() method on teh Actions:

class Actions(models.Model):

date_start_preview = models.DateField('Data Prevista Inicial',
blank=True)
date_end_preview = models.DateField('Data Prevista Final', blank=True)
date_start = models.DateField('Data Real Inicial', blank=True)
date_end = models.DateField('Data Real Final', blank=True)

actionplan = models.ForeignKey(Actionplan, verbose_name='Ações',
related_name='actions')

def save(self, *args, **kwargs):
   # if you want the time "now"
   self.actionplan.date_start = datetime.datetime.now()
   # OR if you want the time to be the same as in the action:
   # self.actionplan.date_start = self.date_start
   # etc etc, do same for each var
   super(Actions, self).save(*args, **kwargs)


(check syntax if you need Timezones:
https://docs.djangoproject.com/en/1.8/topics/i18n/timezones/ , and here are
the docs on method overriding:
https://docs.djangoproject.com/en/1.8/topics/db/models/#overriding-predefined-model-methods
)

Re: i have got a forbidden error in my project plz help for solve it

[Lachlan Musicman]

DHaval,

Attachments wont cut it.

Please paste the code into your email or into http://dpaste.com/

Also, a pyc file isn't a file that is readable by humans - you will need to
send the code from the py file.

You will need to also send the exact error.

Cheers

Re: dhango class based views - Saving post data

Here is my view. 

request.data has the 2 fields I am passing however serializer.validated_data 
has only prefs.


class AddToUserProfile(generics.CreateAPIView):
permission_classes = 
(permissions.IsAuthenticatedOrReadOnly,IsOwnerOrReadOnly)
serializer_class = UserPrefSerializer
queryset = UserPrefs.objects.all()
lookup_field = 'user_id'

#def create(self,request,*args, **kwargs):

serializer = UserPrefSerializer(data=request.data)
print (repr(serializer))
#user=request.user
if serializer.is_valid():
print ("validated_data")
print (serializer.validated_data)  ## Here i get only prefs - 
ItemsView(OrderedDict([('prefs', 'Likes')]))
print (request.data) ## Here I see both address as well as prefs 
{'address': 'XYZ', 'prefs': 'Likes'}

Re: dhango class based views - Saving post data

[James Schneider]

The 'address' field is an FK to the Address model (hence the reference to
'address_id'), and you'll either need to 1) add null=True to the address
field definition in UserPrefs and update your migrations and allow a
UserPref model to not be connected to an Address model, 2) find the right
Address model within your various create/save() method calls and include it
when creating a UserPref object, or 3) Create a new Address object, save
it, and then pass it in when creating the UserPref object.

Sounds like option 3 is the way you want to go since you are including a
string that can be used to create an Address object. That would probably be
best in your create() call so that a new Address object isn't created
whenever you update your UserPref object.

Just keep in mind that you are creating two objects in this view, one
UserPref, and an Address that gets attached to your UserPref. Simply
setting userpref.address to "XYZ" is incorrect.

Re: dhango class based views - Saving post data

address table already has a record of name xyz. Request object has a address

As I am initializing serialize with request.data, why is it that I don't see it 
in validated_data?
Do I need to add address_id to validated_data in my view?

Django session key collision

[Greg]

I've noticed a number of apparent session collisions (i.e., two or more 
users getting the same session key and therefore each others session data) 
on a site I manage. The site is on django 1.3.7, which shouldn't have any 
issues with session key collisions (there were some in earlier django 
versions) but I don't know whether it's entirely thread safe?

How would I go about debugging this? I can't reproduce the bug so at a bit 
of a loss as to how to fix it.

Re: dhango class based views - Saving post data

[James Schneider]

No, it looks like you need to set a model in the Meta class as part of your
ModelSerializer class.

http://www.django-rest-framework.org/api-guide/serializers/#modelserializer

Is "XYZ" a valid slug to retrieve that Address object? You probably need to
provide the PK value for the 'address' rather than some other field,
otherwise you'll be doing some crazy overriding to pull the right Address
object.

Your submitted data dictionary is probably going to look something like
this:

{"address":"14","prefs":"0"}'

Where 14 is the PK of the Address object you want to use.

I'm a little out in the weeds here since I don't have a DRF setup of my
own, so please make sure you read through the docs.

Typically, you won't be submitting the "human readable" version of related
(foreign key) field via POST, it will almost always be a PK. The same rule
applies for any field that has a 'choices' attribute, you would submit the
key value, not the display value. In the case of 'prefs', this would be
"1", "3", etc. rather than "Likes" or "Dislikes", per your Preferences
list.

API's are made for computers to communicate with other computers, not for
people.

Re: dhango class based views - Saving post data

[Shekar Tippur]

James,

I was able to get thro with the save operation. It was quite a bit of 
learning.

Meta section on the model existed but I was not populating validated_data 
properly. I was under the assumption that 

when I did

serializer=UserPrefSerializer(data=request.data)

seriazer object will be populated with post request data.

I had to resort to

 address_obj=Stock.objects.get(symbol=request.data['address'])

 user_obj=User.objects.get(username=request.user)

serializer.validated_data['stock_id']=address_obj.id

serializer.validated_data['user_id']=user_obj.id

I am not sure if this is the optimal way to do it but this seem to have 
done the trick.

Heartfelt thanks for handholding me through this.

- Shekar
