 Hi,

 I need to select form values horizontally but couldn't get it work.

 Following is the code:

 class HorizontalRadioRenderer(forms.RadioSelect.renderer):
   def render(self):
 return mark_safe(u'\n'.join([u'%s\n' % w for w in self]))

 class ResponseForm(models.ModelForm):
 class Meta:
 model = Response
 fields = ('interviewer', 'interviewee', 'conditions',
 'comments')
 def __init__(self, *args, **kwargs):
 # expects a survey object to be passed in initially
 survey = kwargs.pop('survey')
 self.survey = survey
 super(ResponseForm, self).__init__(*args, **kwargs)
 self.uuid = random_uuid = uuid.uuid4().hex
 # add a field for each survey question, corresponding to the
 question
 # type as appropriate.
 data = kwargs.get('data')
 for q in survey.questions():
 if q.question_type == Question.TEXT:
 self.fields["question_%d" % q.pk] =
 forms.CharField(label=q.text,
 widget=forms.Textarea)
 elif q.question_type == Question.RADIO:
 question_choices = q.get_choices()
 self.fields["question_%d" % q.pk] =
 forms.ChoiceField(label=q.text,
 widget=forms.RadioSelect(rende
 rer=HorizontalRadioRenderer),
 choices = question_choices)

 Error:

 class HorizontalRadioRenderer(forms.RadioSelect.renderer):
 AttributeError: type object 'RadioSelect' has no attribute 'renderer'

Dynamic Model ID cannot be called

[Shazia Nusrat]

Hi,

I have a simple model like below:

class Artists(models.Model):
   name = models.CharField(max_length=200)
   description = models.TextField()

   def __unicode__(self):
 return self.name

I am trying to call it in my view like below:

def artistdetail(request, id):
   artista = Artist.objects.get(id=id # this line is giving me
error.


Can someone explain me how to get the id in operational mode. I can call
IDs with filtering by name in shell. But how to set it up for the user who
uses it.


Regards,
Shazia

How to create reusable components in django

[Vivek]

Hello Guys
I am new to django. i am working on a web app and one of the requirements 
in the application is a dropdown list in the header that displays the 
number of users registered to a company that logins( The list is limited to 
just 10 users). so this list needs to be there for all the pages which the 
company has access to.

How do i make this list dynamic. Can i create a reusable component or 
plugin that will just display this in the layout when i call it.
Is there any other way of displaying this.

forms.Form.to_div ? and how override forms.Boundfield.label_tag?

[threesixright]

Hi All,

Just started a few weeks ago with (v1.11) *Django* (coming from Rails) and 
I *love* it! Kudos to all the dev's!

I'm fiddling with creating forms. What would be the best approach to add a 
*to_div* method to the *forms.Form* class ? many frameworks (bootstrap, 
semantic-ui, etc.)  are using:

 https://semantic-ui.com/modules/checkbox.html>">  I agree to the Terms and Conditions 


..to group fields (label + input). 

I understand I can make my own form template and just loop over the fields. 
But nicer would be (imo) if you can use a *to_div* method om the form. 

Another thing I ran into is the usage of the form label. Unlike the input 
fields that you can easily override via the widget html templates, the 
label you can not. This is implemented in the *Boundfield* *label_tag* 
method. What would be the best way to change its default behaviour?

Thanks!

Re: Dynamic Model ID cannot be called

[M Hashmi]

Nothing wrong with your function based view. Just try to fill data in DB
field. It will work. Because you don't have any record in DB. Try to use
'get_or_create' function.

Re: How to create reusable components in django

[Derek]

You can include a template snippet into the body of the main template that 
is rendering your current view.

That snippet in turn can either be passed data (such as a user count) from 
the view that calls the main template - see  
http://code.runnable.com/UpeQSkq7JxN6AANF/dynamic-content-in-a-template-in-django-for-python
 
(but imagine the datetime.datetime.now() function being replaced by your 
own)

You can also create your own "tag" which makes the results from a function 
readily available - this example:
https://stackoverflow.com/questions/40498091/how-do-i-register-a-dynamic-inclusion-tag-within-django
looks like it might help you.

Crispy forms not showing bootstrap and save/submit button

[Gabriel - Iulian Dumbrava]

Maybe it's because you have instructed crispy to not generate the form tag and 
you have not added it yourself in the HTML code.

Django Group Models

[yingi keme]

What will be the best approach to designing a database schema that groups users 
in a collection of 4?

How will you create a model for lets say in an online game setting such that 
you want only 4 players in a single group based on thesame criteria amongst 
players?

Creating this model is problematic for me.

return reverse("accounting:invoices:detail", kwargs={"pk": self.pk})


The 'their_company' field I think is whats giving the error. I think it is 
because it is trying to convert that field to an int but its not something 
that can be converted to an int. I'm new to django and I know I have 
something configured wrong somewhere but not sure where. 

Thanks for your help

Re: Django Group Models

[threesixright]

Very roughly.

Something along the lines of this
I would create a Player (players) and a Match (matches) tables. 
The match table contains 4 keys (player1, player2, player3, player4) and some 
extra fields (created, status, etc.)
For each player you store some type of a skill (number) and a status 
(offline,lobby, playing, available), then alias, ping, etc.
The match-making logic could search for players within a certain skill range

The problem lies in this line:

For some reason last_invoice_num is an invalid value to pass to
int().  You'd have to check what that actual value is that you're
passing to the function.  The error message *should* specify what
that value is:

>>> int("x")
Traceback (most recent call last):
  File "", line 1, in 
ValueError: invalid literal for int() with base 10: 'x'
>>> int("")
Traceback (most recent call last):
  File "", line 1, in 
ValueError: invalid literal for int() with base 10: ''

but you seem to have truncated it so it's a little hard to tell from
the error message.  It's not None as that produces a different
message:

>>> int(None)
Traceback (most recent call last):
  File "", line 1, in 
TypeError: int() argument must be a string, a bytes-like object or a
number, not 'NoneType'

[Alexander Joseph]

Hi, thanks for the reply, however when I take out the 'their_company' field 
altogether everything works fine. Also in the error it references the 
their_company field. The entire error is  *"invalid literal for int() with 
base 10: 'NewCor'"* NewCor is a company in the contacts table. Thanks

I'm using {{ form.as_p }} in my template and would like to be able to use

in the init method of your form do something like this:

self.fields['verification_date'].widget.attrs["placeholder"] = 'date'

Re: ValueError: invalid literal for int() with base 10:

[Alexander Joseph]

The problem was I had records in the database from before I changed the 
'their_company' field to a ForeignKey. Before it was a CharField so some of 
the records had actual company names in them. I deleted those records since 
there wasnt any real data in there anyways, just dummy data. Everything 
works the way its supposed to now.

If you can do it in the model that is where it should be done.

I could be wrong but I believe fundamental business rules should be 
built into the model as well.


So I override the model.save() method to do the auto-fill and override 
the model.clean() method for business rules. The model clean() method 
gets called by form.is_valid() automatically on saving in the browser 
and can raise an exception if for example some perfectly valid data 
violates a business rule.


https://docs.djangoproject.com/en/1.10/ref/models/instances/#validating-objects

Consider that down the track you wish to make a phone app with access to 
your database. The only reasonable way to do that is via the model API. 
That means you have to do the work in your phone app that you did in 
your web form. It is likely easier to just call the model.full_clean() 
method before model.save() in the API.

Django is very comprehensively documented and almost any question you
can think up is only a google search away. Typically a search will
reveal a Django doc reference and StackOverflow answers. I must say
looking up the docs is very valuable because you learn so much else
besides your original quest.

Books are another good source. My preferred one is Two Scoops of
Django.
