Re: Class Base View Foreign key

This is what my code looks like and it now works :

see where it says "example of setting pk..." below:

if request.user.is_superuser:

   super_user = "superuser"

else:

if form.is_valid():

menu_id  = request.POST.get('menu_id', '')

menu_id  = menu_id.replace(" ", "")

menu_title   = request.POST.get('menu_title', '')

menu_notes   = request.POST.get('menu_notes', '')

menu_fb  = request.POST.get('menu_fb', '')

menu_link= request.POST.get('menu_link', '')

menu_align   = request.POST.get('menu_align', '')

menu_order   = request.POST.get('menu_order', '')

menu_status  = request.POST.get('menu_status', '')

menu_admin   = request.POST.get('menu_admin', '')

menu_image   = request.POST.get('menu_image', '')

#

# example of setting pk :

menu_dropdown = buttons.objects.get(pk=buttons_pk)

#

menu_new_window  = request.POST.get('menu_new_window', '')

menu_scope  = request.POST.get('menu_scope', '')

current_user = request.user

menu_user  = current_user


p = menuX(menu_id=menu_id, menu_title=menu_title,

try:

   p.save()

except:


   messages.error(request, "Menu ID is not unique. Please
specify a different Menu ID.")

   return render(request, 'dyn_menu.html', {'form': form})

return redirect("/theme/dyn_menu_list")

Re: IS it possible to debug Django with Apache and mod_wsgi

[Rob Wilkinson]

DEBUG=Yes in settings.py shows what you need even in Apache

Don’t run like that in prod!

Call for Comments from those who use mailing address models in Django

[Rob]

Do you use postal addresses (place locations) in one or more of your Django 
projects?

Have you used or considered using the open source package *django-address 
<https://github.com/furious-luke/django-address>*?

Are you an experienced Django package maintainer willing to mentor another 
maintainer? 

Hi, I'm one of the new maintainers of the project with not only a lovely 
namespace, but important function for many Django applications.

We're working to get this project updated and build on the author's past 
work.

To help kick things off, we're looking for community feedback.

If you deal with addresses regularly and especially if you have 
rolled-your-own address model architecture, we want to hear from you!

   - Here is an issue for offering comments on storing addresses 
   <https://github.com/furious-luke/django-address/issues/98> in Django 
   applications.
   - If you are an experienced maintainer of open source Django / Python 
   projects and would be willing to help advise / provide mentorship to a new 
   maintainer, please email me: r...@perchlive.com.

Thanks and in parting: I was going to make a postal address joke...but I 
just don't have the right delivery.

Rob

Re: Question about makemigrations

[Rob W]

"Migrate is basically the old syncdb but it takes into account all the 
migrations made by makemigrations. You should run the command -migrate- after 
adding a new app under the INSTALLED APPS section in the settings.py file in 
order to synchronize the database state with your current set of models.”

Re: could not connect to server: Connection refused Is the server running on host "localhost" (::1) and accepting TCP/IP connections on port 5432?

[Rob W]

First, you should not share your password to your server to anyone….thats very 
dangerous.  Now anyone can log in to your server with nefarious intentions.  
Be more careful.

But it sounds like something on the server is blocking your connection.

Need help with project

[Rob W]

There are a few of us in a group slack who are trying to build a working 
production django ap for reporting. 
We are looking for someone who really knows Django to guide us through this 
project.

We are all really hoping that someone will be kind enough to guide us and 
help us build this app.

it's simple, we are connecting to a remote mysql db, which i also setup in 
Azure for sync purposes.

so we are creating a login capability, reset, forgot password, etc.

then on the dashboard we simply want to generate reporting from this remote 
db.

I am hopeful someone will help us.

Yes you can.  I do it for an IOT device that we have using Django/python, many

Re: help with URLS.PY

[Rob W]

Sure.

Here is my urls.py

from django.conf.urls import url
from django.contrib import admin
from django.urls import path

from vr_reporting_app.views import HomeView
from vr_reporting_app.views import Local
from vr_reporting_app.views import User
from vr_reporting_app.views import School


urlpatterns = [
path('', HomeView.as_view(), name='home'),
path('User/', User.as_view(), name='user'),
path('Local/', Local.as_view(), name='local'),
path('School/', School.as_view(), name='school'),   
   
path('admin/', admin.site.urls),
]

Here is my view.py

from django.shortcuts import render
from django.views.generic.base import TemplateView

class HomeView(TemplateView):
template_name = 'dashboard.html'

class Local(TemplateView):
template_name = 'local.html'

class User(TemplateView):
template_name = 'user.html'

class School(TemplateView):
template_name = ‘schoolreporting.html'

Also had to add {% load staticfiles %} to my html pages
And added a tag to each css reference.

Can you send a copy of your models.py or a copy/paste of the class that shows 
the error?

problems with url and views - new to django

[Rob W]

setting up a new project.
all good, loaded up the project on localhost.

however, when creating a view then setting the url, it doesn't work.


*urls.py*

from django.contrib import admin
from django.urls import path

urlpatterns = [
path('admin/', admin.site.urls),
path('hello/', lct_app.site.urls),
   

*views.py*

from django.shortcuts import render

def hello(request):
   return render(request, "lct_app/templates/hello.html", {})

i comment out the path in urls.py, django comes back. what am i missing?

Re: How to properly use MySQL Generated Fields in Django

[Rob Schneider]

Thanks!

I’ll give this a try.

I did have “alpha” as a function in the model, but found I could not easily 
include that in queries as easily as a field in the db. so into the db it went. 
 I’ll try this, and see if I can get the data out as wanted.

thanks!

Re: Smiley in url triggers 500 error

Ok solution was simple. I had to add this in settings.py in the database 
section:
’OPTIONS’: {’charset’: ’utf8mb4’},

Smiley in url triggers 500 error

[Rob]

Somebody linked our site with a smiley in the url. The url looks like this:
myurl/nummer-333邏/
This results in a 500 error.

Because this page does not exist I expected a 404 error. The 500 error 
shows:
(1267, "Illegal mix of collations (latin1_swedish_ci,IMPLICIT) and 
(utf8_general_ci,COERCIBLE) for operation '='")

Because latin1 doesn't support smileys I converted my database and tables 
to utf8mb4_unicode_ci (I saw several site advising against using 
utf8_unicode_ci with mysql)

Then I got this error:
(1267, "Illegal mix of collations (utf8mb4_unicode_ci,IMPLICIT) and 
(utf8_general_ci,COERCIBLE) for operation '='")

So the database conversion worked (no other encoding problems with the 
site) but still the error. I changed my my.cnf to:
[mysqld]
local-infile=0
innodb_file_per_table
bind-address=127.0.0.1
character_set_server=utf8mb4
collation_server=utf8mb4_unicode_ci

[client]
socket=/usr/local/mysql/data/mysql.sock
default-character-set = utf8mb4

[mysql]
default-character-set = utf8mb4

But still the same error. Anybody an idea?

More info:
Database: mysql  Ver 15.1 Distrib 5.5.46-MariaDB, for Linux (x86_64) using 
readline 5.1
Django: 1.11.4
Python: 3.4.2

Django formset security and injecting PKs in formset hidden id fields

[Rob Ladd]

I've noticed something troubling in Django formsets:

Each formset.form has a hidden field with the id of the model being edited. 

All one would need to do is change this id and submit, and the default 
formset clean() or save() methods don't bat an eye.


I would think that it wouldn't be too complicated to keep track of which 
objects were in the original formset queryset, and compare them on save. 

Given all the other convenient security methods we have, I wonder why 
Django doesn't do this already?

Re: Django formset hidden id field

[Rob Ladd]

Carl Meyer said:

"Whatever queryset you pass to the model formset limits the 
available rows for editing. The end user can edit the PK to refer to any 
item in that queryset, but not any item in the table. "

That's not true, based on my observation. 
As long as the PK refers to any object of that type, it can be edited by 
monkeying with the hidden id field.
I think that's a pretty big gotcha, since we have conveniences like 
permission_required decorator, {% csrf_token %}, etc.

Re: Does anyone use Django on bluehost? "Cant find fcgi module" error on line 9 .

[Rob Groves]

I am using Django on bluehost.  I suspect that the issue you are seeing is 
that Django1.9 has stopped supporting fcgi.  I found that out when I tried 
to upgrade from 1.8 a while back.  I think you can probably copy over the 
fcgi module from the Django 1.8 release, but I haven't tried that.  I just 
stayed at 1.8, since it is still under support.  I figured I'd deal with it 
later when I have to move to 1.9.

Re: Binding model data to a formset without POST

[Rob Groves]

Thanks for the reply Collin, and thanks for the warning about this being 
more complicated than it seemed at first.  I later discovered that I needed 
to set the hidden fields that contain the foreign and instance keys as 
well.  For completeness, the below code is working for me given the fact 
that I only have simple fields.

# helper functions
def bind_formset(formset):
"""
Bind initial data to a formset
"""
if formset.is_bound:
# do nothing if the formset is already bound
return formset

bindData={}
# the formset.get_default_prefix() and form.add_prefix() methods add in 
the 
# dict keys that uniquely identify the various form fields with the 
individual 
# instance data

# add formset management form data
bindData[formset.get_default_prefix()+"-TOTAL_FORMS"]=str(formset.
management_form['TOTAL_FORMS'].value())
bindData[formset.get_default_prefix()+"-INITIAL_FORMS"]=str(formset.
management_form['INITIAL_FORMS'].value())
bindData[formset.get_default_prefix()+"-MIN_NUM_FORMS"]=str(formset.
management_form['MIN_NUM_FORMS'].value())
bindData[formset.get_default_prefix()+"-MAX_NUM_FORMS"]=str(formset.
management_form['MAX_NUM_FORMS'].value())
for form in formset:
if form.instance:
# field data, get these values from the instance
for fieldName,fieldValue in form.fields.iteritems():
try:
bindData[form.add_prefix(fieldName)]=getattr(form.
instance,
 fieldName)
except AttributeError:
# this is an added field (i.e. DELETE), not derived 
from the
# model, do nothing with it, since we are only binding 
instance
# data to the form
pass
# hidden field data, get these from the field initial values set
# when the form was created
for field in form.hidden_fields():
bindData[form.add_prefix(field.name)]=field.field.initial
# create a new bound formset by passing in the bindData dict, this looks

Binding model data to a formset without POST

[Rob Groves]

Hi All,
I am new to Django and am enjoying it very much.  Excellent documentation, 
tutorials, and general environment to work in.  Good job Django developers!

I have a question on binding data to a ModelFormset.  I have looked 
extensively and not seen this particular issue covered before.

I have a ModelFormset that I send to a template for custom rendering so I 
can present the fields in a controlled tabular format.  The ultimate goal 
is to use CSS to create a red bounding box around any fields with 
validation errors and to set the "title" attribute of those input fields so 
that the user can see what errors were generated  by hovering over the red 
bounded field.  This presents a nice clean interface when there are 
errors.  It all works great, with one annoyance if the model data starts 
out with values that will generate validation errors (i.e. missing required 
data).  

I initially call the view with a GET, which creates the forms and populates 
the form fields.  Since the data is not bound to forms at this point, I 
can't validate and set the errors.  In order to validate the fields and set 
the table error borders, I have to submit the form using POST to bind the 
data, validate the form and generate the errors which ultimately set an 
error_class for styling the table.  This means that I have to "save" the 
from from my form page to get the table style I want.

What I really want is to instantiate a ModelFormset, setting the instance, 
but then to bind the data present in the instance and set errors by sending 
is_valid() to the formset before rendering (i.e. on initial page rendering 
with the GET, so no POST data).  It seemed to me that there should simply 
be a bind_instance() function for all ModelFormsets that contain an 
instance.  I looked and didn't find that.  Eventually, I just decided to 
bind the data myself manually using the following helper function:

# helper functions
def bind_formset(formset):
bindData={}
# add management form data
bindData[formset.get_default_prefix()+"-TOTAL_FORMS"]=str(formset.
management_form['TOTAL_FORMS'].value())
bindData[formset.get_default_prefix()+"-INITIAL_FORMS"]=str(formset.
management_form['INITIAL_FORMS'].value())
bindData[formset.get_default_prefix()+"-MIN_NUM_FORMS"]=str(formset.
management_form['MIN_NUM_FORMS'].value())
bindData[formset.get_default_prefix()+"-MAX_NUM_FORMS"]=str(formset.
management_form['MAX_NUM_FORMS'].value())
for form in formset:
if form.instance:
for fieldName,fieldValue in form.fields.iteritems():
try:
bindData[form.add_prefix(fieldName)]=getattr(form.
instance,fieldName)
except:
# this is an added field, not derived from the model
pass
newFormset=formset.__class__(bindData,instance=formset.instance,
  queryset=formset.queryset, error_class=
formset.error_class)
return newFormset

This works!  My question... Is this a reasonable approach?  Or did I just 
miss the obvious way of doing this?

Thanks for any help!

Ok.  Tell the designer to google "chrome accessibility tester

It will then flag the places where the Web Content Accessibility Guidelines

I'm not a designer.  I can't make good suggestions on how to improve 
things, since I would most definitely make it worse.

Clearly.  My audit extension flags 47 contrast problems on the home page

I hate to be "that guy" but this is not really an improvement other than it

How do I start with this project with django

[Rob L]

Hi, 

I hope this is a right place to ask, not very sure where to post on 
internet.
It's about planning a django project, maybe a similar django package has 
been already there, if it's true, I hope someone can tell me which it is.

The feature list of the project I am wishing to do is:

   - Let users upload some images(a folder contains image files)
   - Backend generates static htmls to present those images, basically as 
   a gallery, via an generated url
   - User can select from default themes(templates)
  - The template I am talking about here is not django template, they 
  are a bunch of xhtml, css and js files can be choose from default or 
  uploaded by user. 
   - User can upload and use their customized templates
  - I made a local Python program that can work for the purpose 
  here: https://github.com/viewplatgh/pgal, maybe can help you understand 
the 
  feature I am trying to implement on the django project
   - The workflow is quite similar to http://codepen.io, but what user 
   inputs are images, optionally templates, css and js files, rather than html 
   file itself. The htmls are generated by django app, and create a short url 
   for people who uploaded/built their resources to view the gallery.

I know this app don't have to be implemented by using django. I 
choose django because Python is the language I'm familiar with and it's the 
framework I have a little experience with, but to implement such a site I 
have so many questions and don't know where to start. I don't expect an 
exact answer to this post, but just hope to collect more helpful 
information, resources and ideas from experienced programmers to help me 
kick my project off...

Here is some questions in my mind currently:

   - Would django allow me to write a bunch of files at backend? 
   - Unlike php, django's urls don't map to server's folders. But I need 
   that feature to let user view the generated statics. How do I work through 
   this. Should I generate django templates?
   - How to prevent user from uploading malicious stuff to backend...

Any suggestions, ideas would be appreciated. Thanks! 

Thanks
Rob L

Re: problem with deploying django using mod wsgi

[Rob Ladd]

It may be looking in html because it isn't getting the definition from the 
view method or class, so it's going with the default.
Try importing everything in views:
from webapp import views *

How to update a form in formwizard

[Rob]

I have a problem with formwizard. In step 3 of the wizard I use a filtered 
query which depends on choices from step 1 and 2. My wizard works fine when 
moving forward, but when a user presses previous, or changes the choices of 
step 1 and 2, things go wrong (validation error or filters won't work).

Here is my forms.py:
class BoekForm3(forms.Form):
Activiteit = forms.ModelChoiceField(queryset=Activiteit.objects.all(), 
empty_label="(Nothing)")

If I use queryset Activiteit.objects.none() in forms.py the correct fields 
in step3 of the wizard show up right, but the step3 always give a 
validation error.

If I use queryset Activiteit.object.all() in forms.py the correct 
(filtered) fields show up in step3 when going forward, and the form 
validates. However when a user presses previous in step4 the filter is 
gone, and all choices are available.

I think that the fields are updated moving to step3, but the form isn't. I 
have included my views.py below.

class BoekingWizard(SessionWizardView):
def get_template_names(self):
return [TEMPLATES[self.steps.current]]

def get_context_data(self, form, **kwargs):
plaatjes = Activiteitsgroepen.objects.all()
context = super(BoekingWizard, self).get_context_data(form=form, 
**kwargs)
if self.steps.current == 'step1':
context.update({'plaatjes': plaatjes})
return context

def get_form(self, step=None, data=None, files=None):
form = super(BoekingWizard, self).get_form(step, data, files)
if step == 'step3':
x = self.get_cleaned_data_for_step('step1') or {}
filter1 = x['Type_activiteit'].Groep
y = self.get_cleaned_data_for_step('step2') or {}
if y['Aantal_personen'] < 76:
filter2 = 'kleinere groepen'
elif y['Aantal_personen'] > 76:
filter2 = 'grotere groepen'
else:
filter2 = 'geen selectie'
reeks = ['1','2','3']
if y['Dagdeel'] in reeks:
filter3 = 'Dagdeel'
elif y['Dagdeel'] == '4':
filter3 = 'Hele dag'
elif y['Dagdeel'] == '5':
filter3 = 'Middag + Avond'
elif y['Dagdeel'] == '6':
filter3 = 'Dag + Avond'
form.fields['Activiteit'].queryset = 
Activiteit.objects.filter(Soort__Groep = filter1).filter(Grootte__Naam = 
filter2).filter(Dag__Omschrijving = filter3)
return form

I asked a similar question a few days back, but now it is much clearer to 
me were the problem must be, so I did a rephrase of my question.

Any help would be highly appreciated.

Rob

Re: get_form in formwizard gives validation error

[Rob]

I am a bit further now. When I use the default widget in forms.py the 
validation error disappears. BoekForm3 becomes:
Activiteit = forms.ModelChoiceField(queryset=Activiteit.objects.all(), 
empty_label="(Nothing)")

I ran into another issue however (below is my complete view):
I use get_form to make a custom query. When I go forward in the wizard it 
runs as it should, all filters are applied. However when I use the previous 
step button, the filters won't work, and the user can select all options.

def get_form(self, step=None, data=None, files=None):
form = super(BoekingWizard, self).get_form(step, data, files)
if step == 'step3':
x = self.get_cleaned_data_for_step('step1') or {}
filter1 = x['Type_activiteit'].Groep
y = self.get_cleaned_data_for_step('step2') or {}
if y['Aantal_personen'] < 76:
filter2 = 'kleinere groepen'
elif y['Aantal_personen'] > 76:
filter2 = 'grotere groepen'
else:
filter2 = 'geen selectie'
reeks = ['1','2','3']
if y['Dagdeel'] in reeks:
filter3 = 'Dagdeel'
elif y['Dagdeel'] == '4':
filter3 = 'Hele dag'
elif y['Dagdeel'] == '5':
filter3 = 'Middag + Avond'
elif y['Dagdeel'] == '6':
filter3 = 'Dag + Avond'
form.fields['Activiteit'].queryset = 
Activiteit.objects.filter(Soort__Groep = filter1).filter(Grootte__Naam = 
filter2).filter(Dag__Omschrijving = filter3)
return form

get_form in formwizard gives validation error

[Rob]

In a formwizard I want to use a custom query, based on previous choices. 
The form renders well, but when the step is submitted I get an "Select a 
valid choice. That choice is not one of the available choices." error

Here is the get_form part in my views.py (simplified):

def get_form(self, step=None, data=None, files=None):
form = super(BoekingWizard, self).get_form(step, data, files)
if step == 'step3':
form.fields['Activiteit'].queryset = Activiteit.objects.all()
   return form

Here is the part from my forms.py:

class BoekForm3(forms.Form):
Activiteit = forms.ModelChoiceField(queryset=Activiteit.objects.none(), 
widget=forms.RadioSelect, empty_label=None)

Anybody an idea about this?

Q about wizard.form.forms

[Rob Slotboom]

Hi,

Django’s documentation shows a sample form wizard template.
In that template there is a conditional tag: {% if wizard.form.forms %}{% 
else %}
I can’t figure out when this condition will ever by met.

Does sombody have a clue?

Cheers and happy coding,

Rob

Re: Custum save on Foreignkey in Admin

[Rob van Dam | Camping het Wieskamp]

Hi Pankaj,

I tested the code at it works perfectly. Thanks again!

I have one question out of curiosity (I don't need this for this 
project). When a ticketitem is deleted, def save_formset is called, but 
no instance is made, hence an error message "instance referenced before 
assignment"


What is the correct way to deal with this?

I don't need this for my current project, so if you don't answer it, it 
is no problem at all.


Regards,

Rob

Button with save and custom action in Admin

[Rob]

In Django 1.4 I am working on a small mailing app, and in the admin change 
page I would like to add a button called "send mailing". When the user 
presses the button the model should be saved first, en then redirected to a 
custom page to view and confirm the mailing before send.

I saw lots of snippets, custom actions etc. etc. but I cannot get it 
working. 

I have add a custom change_form.html in /templates/admin/myapp and 
succesfully added a button. But how do I "tell" Django to do the two 
actions?

When I add name="_save" to the button the model is saved after pressing the 
custom button, but now I need a redirect to a custom page using the currect 
model.

Re: Difficulties using generic views (Tutorial 4, Django 1.4)

[Rob]

Sometimes the browser cache is making trouble too. Especially with Firefox 
I occasionally have this kind of problems. Clear the browser cache, or test 
with a different browser mostly helps.

Re: Validation error with formwizard and formset

[Rob]

The validation error i got was due to a custom view i wrote, and had 
nothing todo my my template etc etc. I switched back to the default example 
view provided by the Django site, and everything works.

Validation error with formwizard and formset

[Rob]

I have a basic formwizard example from the Django 1.4 documentation:
https://docs.djangoproject.com/en/1.4/ref/contrib/formtools/form-wizard/

When I replace the forms with a modelform and a formset i keep getting 
validation errors: 
(ManagementForm data is missing or has been tampered with)

The documentation says:
WizardView supports 
*ModelForms*and 
*ModelFormSets*.
 
Additionally to 
initial_dict,
 
the as_view() method takes an instance_dict argument that should contain 
instances of ModelForm and ModelFormSet. Similarly to 
initial_dict,
 
these dictionary key values should be equal to the step number in the form 
list.

Could anybody provide me with an example? Does the validation error have 
something to do with the instance_dict?

Let say i have these forms:
class Address(models.Model):
street = models.CharField(max_length=20)

class AddressForm(ModelForm):
class Meta:
model = Address

class OrderForm(forms.Form):
Order = forms.ModelChoiceField(queryset=Article.objects.all())

OrderFormset = modelformset_factory(Order)

Redirect form after post, and download pdf

[Rob]

This is probably very easy, but i cannot get this working (Django
1.2).

I want to generate a pdf based on the values of a form, and redirect
the form to a thanks page.

Generating the pdf is no problem, but first generate the pdf to
download, and after that redirect the form the the thanks page doesn't
work at all (because the view "stops" after the return).

Any idea?

Thanks for the reply.

I read the part about the "lazy" querysets and therefore I suspected
the database not to be hit. This also doesn't count for querysets from
a cache. Perhaps I should turn of caching for the menu (are only a few
items)

Unfortunately template caching is no option for me, because the menu
items depend on a session.

filter cache output

[Rob]

I have setup caching with memcached for my site. This works well
except from this part of my view. My idea was to store all menu items
in the cache, and apply a filter later on to decide if they belong to
the left or top menu.


menu = cache.get(menu_cache_key)
if menu:
menu_left = menu.filter(menu_left = True)
menu_top = menu.filter(menu_top = True)

I thought that apply the .filter() on the menu would not cause a query
on the database, but it does. So the menu is retrieved from the cache,
and after that the menu items are retrieved from the database (which
makes the caching useless). I found out about this because changes in
the menu are applied immediately on the webpage.

Is this normal behaviour, and should I make multiple entries into the
cache for the left- and topmenu, or is there a way to get this
working?

Re: Seeking a Django 1.3 and syslog configuration example

[Rob]

Well that worked but I'm not happy about it.  I have the following:

from logging.handlers import SysLogHandler

...

'syslog':{
'level':'DEBUG',
'class': 'logging.handlers.SysLogHandler',
'formatter': 'verbose',
'facility': SysLogHandler.LOG_LOCAL2,
},

If I specify 'class' as SysLogHandler instead of
'logging.handlers.SysLogHandler' I get an error:

ValueError: Unable to configure handler 'syslog': class SysLogHandler
has no attribute 'split'

If I just import logging and use
logging.handlers.SysLogHandler.LOG_LOCAL2 I get another error:

AttributeError: 'module' object has no attribute 'handlers'

Very bizarre behaviour all around but I'm up and running.  Thanks for
everybody's help!

Thanks, but this doesn't help at all.  I have no problem getting the
RotatingFileHandler working, it is documented albeit poorly, but the
SysLogHandler isn't documented at all and doesn't work the same way.

The SysLogHandler actually has to connect to syslogd and log to a
syslog facility (eg. LOG_USER or LOG_LOCAL0).  How do I configure
those
options?

Re: Our new startup site build on Django and GAE is now live!

[Rob]

I spent a few seconds looking for the X to close the sign up panel
before
seeing this:

"LOCQL is a social Q service, so we need you to sign in instead of
browse anonymously."

But I *always* browse anonymously first to see if a site is something
I want to use and/or trust with any info about me; if I like it I
will sign up.

I'd like to provide feedback but the first thing you want me to do,
before even looking at the site, is give you my facebook info?
Ummm ... no.  So the only feedback I have is get rid of that "*we're*
social so *you* have to share" attitude.

Seeking a Django 1.3 and syslog configuration example

[Rob]

I'm having no luck finding any information on setting up syslog
logging with Django 1.3 dictionary configuration. The Django documents
don't cover syslog and the python documentation is less than clear and
doesn’t cover dictionary config at all. I've started with the
following but I'm stuck on how to configure the SysLogHandler.

LOGGING = {
'version': 1,
'disable_existing_loggers': True,
'formatters': {
'verbose': {
'format': '%(levelname)s %(asctime)s %(module)s %
(process)d %(thread)d %(message)s'
},
'simple': {
'format': '%(levelname)s %(message)s'
},
},
'handlers': {
'syslog':{
'level':'DEBUG',
'class':'logging.handlers.SysLogHandler',
'formatter': 'verbose'
},

},
'loggers': {
'django': {
'handlers':['syslog'],
'propagate': True,
'level':'INFO',
},
'myapp': {
'handlers': ['syslog'],

Re: Example uses of Celery

[Rob]

I use celery for the following:

1. Expensive tasks that you don't want the user waiting on.  For
example: sending messages;
   we have triggers for SMS, Email and iPhone APN messages.  I don't
want the request/response
   waiting around while I do all of that.
2. Tasks that could fail and need to be retried.  For example:
updating settings on
   the backend, you don't need complicated retry logic.
3. Replacement for cron.  The biggest issue with cron is that it is
single server.
   Once I switched to celery I don't care which processing server
launches the task.

HTML size confusion.

[Rob]

Hi there,

In my ModelForm I have a fields like this:

argument= models.CharField (max_length=50, blank=True)
media   = models.CharField (max_length=50, choices =
getChoices ('media'))

For the 'media' field, the max_length results in a HTML select such
as:


  -
  monkey.png
  shu-eumura-lcd.mpg


The problem here is that the max_length attribute has been passed to
the  size, which results in a very large select control. If
max_length specifies the database storage size, why is it also used as
the size attribute to ?  (Or rather: what am I doing wrong
here?)

I'm using django 1.2.1.

Cheers!

Rob

Re: File Uploads Form Field "title" Questions

[Rob McQueen]

I think this is trivial considering that the example does not use
request.POST['title'] They must of just forgot to use the title field in the
view?

One practical example could be to use the title as the filename which you
intend to store in your filesystem. You can do this by changing the filename
of the file object to the "title" string you stored in the request. This
would be done in a view method.

Thanks for the reply.

The Problem is that I want to fetch a list of categories from the
database, so the amount of categories could vary. I could add them
manually to urls.py but that's not my preferred way.

So if a user enters mydomain.com/main1/page1 --> check if main1 exists
in the database --> render a menu of all pages which are linked to
main1 --> show page1

main categories in menu

[Rob]

I want to make main categories on my site like:
/main1/page1
/main2/page2
/main3/page3

I would like to make those categories dynamically with a m2m . In that
case I can assign pages to one or more main categories.

I have a problem now with urls.py As far as I know I can only "catch"
one variable like:
(r'^main1/(.*)/$', view), In this way I have to add every main
category manually to urls.py

Is there a way to do something like: (r'^(.*)/(.*)/$', view), (I know
this doesn't work)

Or should I catch everything from the url and try to split the url in
the view?
(r'^(.*)$', view),

A consideration I have that I will end up having double content (which
is bad for Google). Is it also an option to remember the choice made
in a session, and render the menu on page load (through middleware)?

Re: inheriting User class

[Rob]

Probably most of us are using the separate profile model, as
recommended.

I actually have multiple models associated with users on one project:

User (from auth)
UserInfo (things rarely accessed such as address, emergency contact
info, etc.)
UserProfile (my application specific profile)

I'm going to break UserProfile into EmployeeProfile and StudentProfile
at some point or keep UserProfile add the other two profile types.
Depends on how looking into Django model polymorphism goes :-)

I prefer the separation of profile and login in my case.  Many
students do not want or need logins to the system.

form model def save question

[Rob B (uk)]

Been struggling over at 
http://stackoverflow.com/questions/3652585/simple-django-form-model-save-question
to get a solution.

I want the inuse field to update to to True when LocationForm is
saved.  For example there would be a list of locations added by the
admin (London, New York and Paris) all with inuse of False.  The user
would select London and submit the form and the inuse field for London
would become True.

Models and forms:

class Location(models.Model):
place = models.CharField(max_length=100)
inuse = models.BooleanField()
class Meta:
ordering = ('place', 'id')

def __unicode__(self):
return self.place

class LocationForm(ModelForm):
class Meta:
model = Location

class Booking(models.Model):
name = models.CharField(max_length=100, verbose_name="Your
name*:")
place = models.ManyToManyField(Location, blank=True, null=True)

def __unicode__(self):
return self.name

class BookingForm(ModelForm):

class Meta:
model = Booking

def save(self, commit=True):
booking = super(BookingForm, self).save(commit=False)
if commit:
booking.save()
for location in booking.place.all():
location.inuse = True
location.save()


Code saves fine but the location.inuse field is not saved to True.
Any ideas where I'm going wrong?

Best intranet solution for a small digital agency?

[Rob B (uk)]

I work for a small digital agency (10-15 employees).  We design and
build websites (using php and Django).  Are we better off building our
own intranet using django or going for a pre built (free or paid for)
solution?

Key features needed:

 - Project management (basecamp clone)
 - Time reporting
 - Local and external file sharing (dropbox clone)

override a form field, to allow usernames with '@'

[Rob]

Hi,

I'm trying to allow usernames that have '@' in them, so they can just
be email addresses.  Maybe this is a bad idea.  ...  But putting that
aside for a second... The admin user forms don't validate with '@' in
usernames, so I thought I'd try this, which I copied from an older
post in this group.

from django.contrib.auth.admin import User, UserChangeForm,
UserCreationForm, UserAdmin

class OurUserChangeForm(UserChangeForm):
username = forms.EmailField

class OurUserCreationForm(UserCreationForm):
username = forms.EmailField

admin.site.unregister(User)
UserAdmin.form = OurUserChangeForm
UserAdmin.add_form = OurUserCreationForm
admin.site.register(User, UserAdmin)

But it doesn't work.  The user form is still validating with the
'username' from the superclass, which is a RegexField.  Is this
working as designed?  Are you not allowed to override a field?

thanks,
Rob

Re: OS X install, not in home directory?

[Rob]

Doh!  Problem solved...  I had created a ~/.pydistutils.cfg file a
couple weeks ago, for some stupid reason I can't remember.  I forgot
to delete that file.  It's contents were:

[install]
install_lib = ~/Library/Python/$py_version_short/site-packages
install_scripts = ~/bin

So it was overriding the normal setup.py behavior.

Re: Getting a Blog included in the Django community aggregator

Re: OS X install, not in home directory?

[Rob]

Thanks, but none of those suggestions seem to work.  I'm not going to
worry about this since I've got too many other things to do, (plus I'm
in China and so to read a google group I have to use a proxy/tunnel),
but for the record here's some more info...

I think I'm using the system python...

RobsMac-2 Django-1.1.1 $ which python
/Library/Frameworks/Python.framework/Versions/2.6/bin/python

--prefix is having no effect, but I'm not sure what to set it to given
the OS X directories...

RobsMac-2 Django-1.1.1 $ sudo python setup.py install --prefix=/
Library/Frameworks/Python.framework/Versions/2.6
running install
...
Removing /Users/rob/Library/Python/2.6/site-packages/Django-1.1.1-
py2.6.egg-info
Writing /Users/rob/Library/Python/2.6/site-packages/Django-1.1.1-
py2.6.egg-info

So it put in my home dir.  Same with --prefix=/Library/Python/2.6.

Using --install-base does produce this error...

RobsMac-2 Django-1.1.1 $ sudo python setup.py install --install-base=/
Library/Python/2.6
running install
error: install-base or install-platbase supplied, but installation
scheme is incomplete

PYTHONPATH is nothing.

OS X install, not in home directory?

[Rob]

Hi,

Maybe this is more of a general python question, but when I run `sudo
python setup.py install` it insists on putting the django package in ~/
Library/Python/2.6/site-packages.  I want to install it in the system
site-packages, so it get's picked up by apache and mod_wsgi.  For now
I'll hand copy the files, but there must be a way with setup.py.  ?

thanks,
Rob

Template translation

[Rob Charlwood]

Hello all,

I'm a little stuck working with some template filters in django in a
multi-lingual site.
Basically some of our content in an Arabic version is not being
translated and so we need some of template filters to just output in
English. However they continue to output in Arabic.

The main template filters I am having problems with is
'filesizeformat' and 'date'. Now I totally understand why Django
inherits this behavoiur and it makes sense to me. However our clients
are keen to have the filters not translated. So my question is, is
there a way to force template tags not to translate?

Something like
{{doc.download|filesizeformat|no_trans}}

If not is there any other way to force certain template tags not to
translate?

Many thanks in advance.

Count number of objects with no ManyToMany connections

[Rob Carlson]

I want to find how many Resources in my dataset have no Widgets associated with 
them.  Resources and Widgets have a ManyToMany relationship:

class Resource(models.Model):
   widgets = models.ManyToManyField(Widget, null=True, blank=True)

I finally settled on the code below, but I was wondering if there was a better 
way to express this:

print "No widgets", 
Resource.objects.exclude(widgets__in=Widget.objects.all()).count()

Thanks!

Re: Check if django is getting a page from memcache

[Rob Hudson]

You can telnet to memcached and run the `stats` command.  That'll tell
you overall hits and misses (plus other info).  If you're using
Django's page caching middleware, you'll see 2 hits per page because
Django caches both headers and page content.  The page load you should
see 2 misses.  Then all subsequent page loads you should see the hits
counter increase.

Re: django-debug-toolbar and 404's

Can you test it by disabling the debug toolbar middleware?  I've
duplicated your exact settings as much as I can and it's working for
me.  If disabling the middleware makes the admin appear, then it would
seem something in the toolbar is causing the problem.

And you are right... those settings you refer to are optional.

Re: django-debug-toolbar with runserver not running on localhost

[Rob Hudson]

Or use the SHOW_TOOLBAR_CALLBACK to customize when you want the
toolbar displayed... I simply ship with what I consider reasonably
safe defaults.  For example:

# Always show the toolbar

DEBUG_TOOLBAR_CONFIG = {
'SHOW_TOOLBAR_CALLBACK: lambda req: True,
}

# Only show toolbar for super user

def custom_show_toolbar(request):
if request.user.is_superuser:
return True
return False

DEBUG_TOOLBAR_CONFIG = {
'SHOW_TOOLBAR_CALLBACK': custom_show_toolbar,
}

Django or CMS.

[Rob B (uk)]

The design agency I work for are looking into CMS options.  Being a
Django man myself I'm hoping to convince them to build one using
Django.

Requirements are roughly:

Page control (creation/drafts/published/withdrawn/deletion)
Page revisions
View draft pages on site for testing
In-place editing for simple text updates
Categories
Editable Navigation
Wysiwyg editors
Image upload (mass select)
Tagging (pages, images, clients)
Smart site search
Limiting user publishing rights

I can't seem to find a decent CMS that would fit the criteria.  What
are people's opinions / experiences with CMS'?  What would you
recommend?  Thanks

problems getting the development version running on Leopard

[Rob Slotboom]

I followed all instructions regarding the intallation of the
development version of Django on Leopard.
I’ve created the symbolic links but I keep getting two error messages:

The first one trying to rum django-admin.py  >>>> command not found
The seccond trying to import django in the python shell   >>>>  No
module named django.core

I can see the symbolic links in finder and the show the content the
should give.

Some time ago I used exactly the same procedure on FreeBSD and all
went fine.

Do I have to something special to get this running on Leopard?

Cheers,

Rob

Re: debug toolbar problem

[Rob Hudson]

It's looking like you have DEBUG=False and rely on
request.user.is_superuser to enable the toolbar.  Which mostly works,
except...

The Django Debug Toolbar monkey patches the CursorDebugWrapper class
to collect its data about what SQL queries are being executed:
http://github.com/robhudson/django-debug-toolbar/blob/master/debug_toolbar/panels/sql.py#L130

And this only gets used as a database cursor within Django when
settings.DEBUG=True:
http://code.djangoproject.com/browser/django/trunk/django/db/backends/__init__.py#L82

So when DEBUG=False, it uses a normal cursor which doesn't track SQL
queries.

models.Manager error

[Rob B (uk)]

Model: http://dpaste.com/96349/

View:
def game_list(request):
return render_to_response('games/game_list.html',
  { 'object_list':
GameList.objects.published.all().order_by('position')})


Template error:
AttributeError at /games/
'Manager' object has no attribute 'published'

Would seem my view doesn't like my new manager very much?
