Re: Models as choices
If you're serializing as JSON, that primary key is literally just integer
then, and the foreign key relationship requires an instance of that foreign
key. So you'll need to fetch an instance of the object first.
I've had this issue before, that's how I resolved it.

Re: Cannot Redirect to other page
I did include example, the last sentence of the first paragraph.
You need to get rid of the inner function, I don't know why that was
written. I needs to look more
if request.method =="GET":
return the regular page
elif request.method == "POST":
process the answers that have been sent by the user
Basically follow this,
https://docs.djangoproject.com/en/3.0/topics/forms/#get-and-post
You'll need to make changes to;
1. Your template
2. Removing the inner function
3. Processing the form correctly
4. Handling the GET and POST differently

Re: Capture URL values in a CBV
Hey Tim
The bigger question is, what are you trying to achieve?
With the DetailView, fetching the object with the primary key is already
handled for you, as you've seen the object will already be available in the
template.
This website is very useful to know which functions are implemented in a
class-based view, and which variables are available.

Re: Cannot Redirect to other page
So the "return" inside the inner function won't automatically "trigger".
`redirect` is a shortcut function which constructs a HttpResponseRedirect.
At the moment, you're calling the function, and the HttpResponseRedirect
instance is returned from the function you're not actually doing anything
with it, you're throwing it away. You'd need to either `return verifyGame2`
or save the response `redirect_instance = verifyGame2` and then `return
redirect_instance`
But your flow in this function seems very odd. Your actions are exactly the
same regardless if it's a GET or POST. Your form's submit should be POST
and not a GET (since you're sending data). In that case; your code should
be looking at the request's method, if it's a GET, then render the
game2.html, if it's a POST, then you need fetch the POST data (the answer)
and do the processing as you've done.
It's quite unnecessary to have an inner function in this situation.
Quite a lot to improve on with this FBV.

Filtering Data Based On Foreign Key
Hi all,
I am having an issue dynamically populating form data based on the previous
selected field. In my case I have two models one which contains different
types of memberships associated to different clubs. Then I have another
model which handles registrations for individual clubs.
My problem - when the end-user is ready to sign up the form renders (I
already filter out members based on the club they originally selected) but
I need to filter the price based on the membership selected (foreign key)
of player model.
*Below is my model for the membership types:*
# Model to store clubs available memberships so members can select and
pay on registration page
class ClubMemberships(models.Model):
club_id = models.ForeignKey(ClubInfo, on_delete=models.CASCADE)
title = models.CharField(max_length=30, default='')
price = models.DecimalField(default=0.00, max_digits=6, decimal_places=2)
description = models.TextField()
def __str__(self):
return self.title
*Here is the model for the registration:*
# Model to store player information to be used for membership registration
class Player(models.Model):
club_id = models.ForeignKey(ClubInfo, on_delete=models.CASCADE)
membership_title = models.ForeignKey(ClubMemberships,
on_delete=models.CASCADE)
price = models.DecimalField(max_digits=10, decimal_places=2)
first_name = models.CharField(max_length=20)
last_name = models.CharField(max_length=20)
dob = models.DateField(max_length=8)
email = models.EmailField(max_length=50)
phone = models.CharField(max_length=12)
mobile = models.CharField(max_length=15)
emergency_contact_name = models.CharField(max_length=40)
emergency_contact_mobile = models.CharField(max_length=15)
address1 = models.CharField(max_length=30)
address2 = models.CharField(max_length=30, default='')
address3 = models.CharField(max_length=30, default='')
town = models.CharField(max_length=30)
county = models.CharField(max_length=30)
country = models.CharField(max_length=30)
def __str__(self):
return "%s %s" % (self.first_name, self.last_name)
*Form for player registration:*
# Form to accept details for members to register
class PlayerRegistrationForm(forms.ModelForm):
class Meta:
model = Player
fields = '__all__'
labels = {
'dob': 'Date of Birth'
}
widgets = {
'dob': forms.DateInput(attrs={'id': 'datepicker'})
}
def __init__(self, *args, **kwargs):
super(PlayerRegistrationForm, self).__init__(*args, **kwargs)
self.fields['club_id'].widget = forms.HiddenInput()
def load_price(self, request):
membership = request.GET.get('membership_title')
title = ClubMemberships.objects.filter(title=membership)
self.fields['price'].queryset =
ClubMemberships.objects.filter(price=title.price)
The load_price is an example of what I am trying to accomplish but cannot
get it working. I want the form to *check the membership selected* in the
*form* then *filter* the *price of that membership* and *display it in the
form*.
*Here is my form in the browser:*
[image: image.png]
Would really appreciate any help as I cannot incorporate PayPal until I can
correctly display the price.
Thanks
Gavin

Suggested model structure to achieve users selection of services/package
I am building an application that offers different services, a user can
select and purchase specific needed packages. I want to know the best way
to create the model so that our users can select and once paid it sets the
service to active. I have one model that holds information about each
individual services which includes (Package Title / Description / Price ).
I need another model to handle what services are associated to each user
but I am unsure how to go about this.
I have created two models as shown below but unsure how I can accomplish
the above as I believe there is a better was to accomplish this.
# Model to store club information on what clubs have access to what packages
class ClubPackages(models.Model):
club_id = models.ForeignKey(ClubInfo, on_delete=models.CASCADE)
PACKAGE_STATUS = (
('0', 'Active'),
('1', 'Not Active')
)
player_register_package = models.CharField(default='1',
max_length=1, choices=PACKAGE_STATUS)
player_register_price = models.DecimalField(default=100.00,
max_digits=8, decimal_places=2)
player_register_expiry = models.DateField(default=timezone.now)
roster_package = models.CharField(default='1', max_length=1,
choices=PACKAGE_STATUS)
roster_price = models.DecimalField(default=50.00, max_digits=8,
decimal_places=2)
roster_expiry = models.DateField(default=timezone.now)
rent_a_pitch_package = models.CharField(default='1', max_length=1,
choices=PACKAGE_STATUS)
rent_a_pitch_price = models.DecimalField(default=100.00,
max_digits=8, decimal_places=2)
rent_a_pitch_expiry = models.DateField(default=timezone.now)
shop_package = models.CharField(default='1', max_length=1,

shop_price = models.DecimalField(default=50.00, max_digits=8,
decimal_places=2)
shop_expiry = models.DateField(default=timezone.now)

Filtering choices in a form based on previous field selection
Hi all,
Just quickly to summarize I have an app, which allows clubs to sign up and
carry out different tasks. One of the features is a scheduling / rosters.
Currently I have a form to add times to the roster. The club pages work off
a session key based on the initially selected club.
My form consists of:
*club_id* - which I have hidden and initialized based on the logged in user.
*pitch_id - *which is currently displaying all pitches associated to all
clubs but I need this to *only show pitches based on the foreign key for
the club_id *
Would appreciate any help.
Please see code below:
*form.py *

Using sessions key variables as a url argument
Hi all,
I am not sure if this is possible as I could find nothing online but would
appreciate any alternative solution.
- In my view I obtain a pk which is set as a session key
- I need to pass that session key variable into the url argument.
e.g. http://127.0.0.1:8000/club_home//teams/
Code below, any other samples of code needed let me know
Thanks
Gav
*Main Urls*
urlpatterns = [
url('admin/', admin.site.urls),
url(r'^club_home/', include('clubkit.clubs.urls'), name='clubs'),
]
*Urls.py*
urlpatterns = [
path('', views.club_home, name='club_home'),
path('teams/', views.TeamInfo.as_view(), name='teams'),
path('pitches/', views.PitchInfo.as_view(), name='pitches'),
]
*View.py:*
def club_home(request, pk=None):
if pk:
request.session['pk'] = pk
club = ClubInfo.objects.filter(pk=pk)
club_posts = ClubPosts.objects.filter(club_id=club[0])
else:
club_pk = request.session.get('pk')
club = ClubInfo.objects.filter(pk=club_pk)
club_posts = ClubPosts.objects.filter(club_id=club[0])
args = {'club': club,
'club_posts': club_posts
}
return render(request, 'club_home_page.html', args)

Using signals to populate another model based on new registered user
Hi all,
I am new to working with signals and triggers, what I am trying to
accomplish is:
1. When a new user registers, I have another model to deal with
subscriptions.
2. I want to create an instance for that subscription model with all the
default values based on the new user.
3. Otherwise no object is created in this model and it has to be done
via a form.
Would appreciate any help and if any other code is needed let me know.
*See code below:*

club_name = self.cleaned_data['club_name']
if ClubInfo.objects.filter(club_name=club_name).exists():
raise ValidationError(_("Club already exists"))
return club_name

Re: Working with pk arguments within an included URL
Hi Simon,
That’s a great idea, I’ve only ever worked with built in sessions for
logging in. Would you have a link to some documentation or an example that
would help me as I’m relatively new to Django and this has been holding me
back months now.
Thanks

Hi Pooya,
Once I’ve done the include, how can I then pass that PK into the view of
the included urls?

Writing your first Django app, part 5 Testing
Hi,
I'm on part 5 of the polls tutorial
(https://docs.djangoproject.com/en/1.7/intro/tutorial05/) and I am running
Django 1.7 and Python 3.4 on Windows 8. Just want to make sure I'm on the
right track.
For the following part of tutorial:
>>> # get a response from '/'>>> response = client.get('/')>>> # we should
>>> expect a 404 from that address>>> response.status_code404>>> # on the other

>>> # If the following doesn't work, you probably omitted the call to>>> #

>>> response.context['latest_question_list'][>> Beatle?>] *Seeing What's up? here too*
Instead of getting '\n\n\nNo polls are available.\n\n' , the What's
up poll is coming up i.e. b'r\n\t\r\n\t\r\n\t\tWhat'se up?\r\n\t\r\n\t\r\n? The rest of the
code works fine as in adding the Beatles question but the What's up? question
is also coming up along with the Beatles question. Is this ok? Any help would
be greatly appreciated.
Thanks,
Gavin

Foreign Key Chicken/Egg Inline Fu
Hi-
I'm new to Django, but so far I think it is the bee's knees.
I could use some insight into a problem I'm working on.
Given the following...
-
# models.py
from django.db import models
class Team(models.Model):
name = models.CharField(max_length=30)
# captain is a player- but there can only be one captain per team.
# null and blank are true to allow the team to be saved despite
not having a captain
captain = models.ForeignKey('Player', related_name='team_captain',
null=True, blank=True)
def __unicode__(self):
return u'{0}'.format(self.name)
class Player(models.Model):
first_name = models.CharField(max_length=20)
last_name = models.CharField(max_length=30)
team = models.ForeignKey('Team')
def __unicode__(self):
return u'{0} {1}'.format(self.first_name, self.last_name)
# admin.py
from league.models import *
from django.contrib import admin
class PlayerInline(admin.TabularInline):
model = Player
extra = 8
class TeamAdmin(admin.ModelAdmin):
inlines = [PlayerInline]
list_display = ('name', 'captain')
-
As is, when I create a new team in the admin interface I can add the
players inline, but I have to leave the team captain blank, save the
team, and then go back and change the team and set the captain to one
of the players added previously. This is kind of a drag though.
Is there a way that I can make the team captain be automatically set
to the first player entered inline when the team is saved the first
time?
I 've thought about adding a boolean field to the Player model called
"is_captain", but I want to enforce only one captain per team. If I
were to go this route, is there a way I could make the is_captain
field default to True for the first inline entry but false for the
rest?
Thanks,
-Patrick

Re: Invalid block tag: render_comment_form
Florian,
I've found the following link to be helpful:
http://code.djangoproject.com/wiki/UsingFreeComment
For Django 1.0, you should replaces all instances of "free_comment*" with
just comment*, in both files and function names.
However, I'll add that I'm stuck on a similar problem.
The document asks you to use the following code to display the comment form:
{% comment_form for blog.entry object.id %}
It fails in a very similar way to what you describe. However, if you replace
'comment_form' with 'render_comment_form' you no longer get the error and
you don't get the form either.
Maybe you'll progress further than I have,
-Gavin

Re: Error in django.contrib.comments with {% comment_form_target %}
I'm having exactly the same problem as Brandon above, only I haven't upgraded from .96 to 1.0. This is occurring with a fresh install of 1.0. I've tried all of the suggestions above as well as those in the linked django ticket #8571. Any insights?

Re: specifying a model with a field computed from other fields

Re: specifying a model with a field computed from other fields
You're absolutely right, I could simply compute those values as required. I also confess to not having very much dbase design experience so your commentary is valuable. My question was also partly motivated by the documentation on the _pre_save method, which seemed to suggest it might serve my purpose. My motivation here is there are tables other than Reimburse that will do very similar things, but require some unique attributes. So I was looking for a way to assess expenditures in one place, rather than inspecting multiple tables. Of course I realise common things like count and price belong in expenditures, bit I'm still faced with the issue of needing to associate that expenditure with an Account. And that means if I want to determine the status of an account I need to look at all tables in which expenditures are being made. Modifying Russell's model, I'll add a Order table and put price and count into Expenditure: -- model -- class Account(Model): owner = CharField() class Order(Model): catalogid = IntegerField() vendor = CharField() account = ForeignKey(Account) expenditure = ForeignKey(Expenditure) # diff class Reimburse(Model): account = ForeignKey(Account) reimburse_for = CharField() expenditure = ForeignKey(Expenditure) # diff class Expenditure(Model): price = FloatField() count = IntegerField() account = ForeignKey(Account) I can compute these values by inspecting both the Orders and Reimburse tables. Is that the best way? Comments appreciated. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: specifying a model with a field computed from other fields
thanks for the reply, let me modify your example. class Account(Model): owner = CharField() class Reimburse(Model): price = FloatField() count = IntegerField() account = ForeignKey(Account) expenditure = ForeignKey(Expenditure) # diff class Expenditure(Model): cost = FloatField() account = ForeignKey(Account) the only diff is Reimburse now has a field called expenditure. so how would the creation code work now? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: specifying a model with a field computed from other fields
Thanks for your response and sorry about the cryptic nature of the query. In my model I have a table class (Reimburse) that records an items' unit price, the number of items bought and an account (a ForeignKey) from which the cost (unit price * number of items) will be recorded against. I want to be able to record this transaction in an expenditures table - recording the cost and account. I want expenditures to be a ForeignKey, but I want to create it based on values entered (num_units * unit_cost, account). My question: How can I create a foreign key based on the values entered for other fields? I hope that is clearer. cheers, g --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

specifying a model with a field computed from other fields
Hi, I have a model in which there is a foreign key that I want created using values from other fields. For example, I have a table `A`, with fields `a`, `b` and foreign key `C`. I want to specify a final foreign key field using the product `a`*`b` and value of `C`. I'm aiming at being able to get between tables `A` and `C`. What's a good way of doing this? any thoughts much appreciated. cheers, g --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.
