How to restrict save function in Django admin

[Akshay Mukadam]

Hi,
I have developed application that loads CSV file, if the input received 
while parsing the CSV file in Django admin is wrong, it throws a 
stacktrace, to avoid stacktrace I have handled the exception and I am able 
to show the error message using the Message framework in django. 
But the problem is that when I save the data it shows the error that CSV 
data is incorrect, but it also show save message, how could I override 
this.???
Thank You

Re: Web and mobile app with Django? Kivy? sth else?

[Cal Leeming]

Hi Mariusz,

Short answer - Hack something together in the fastest way possible, don't
worry about it being clean, tidy or even tested. Because if you do, you'll
still be working on this project in 2 years time... Look at using something
like PhoneGap [8], just enjoy the experience and ship it :)

If you genuinely want to start learning this stuff, you need to ask
yourself what it is you want to work on? Do you want to do backend (e.g.
all the server stuff, nothing visual), or do you want to do frontend (all
the visual/pretty stuff the user sees), or both? Are you doing this for
immediate financial gain [7], or a spiritual journey of self discovery and
learning [6]? The world of web dev is changing almost every couple of
months, stay on top of your game by reading blog articles from other
developers and keeping on top of tech new. Personally I use Feedly [9] to
aggregate these feeds into one place. Consider getting an internship
somewhere with other good programmers, learning from inspirational people
will speed up your personal development massively (I wish someone had told
me this 8 years ago).

Long answer;

Responsive/adaptive design does not necessarily make a good mobile
experience, and rarely will you find a mobile app which has the same
workflow as the website. Ideally you need to storyboard each experience and
wireframe the UX accordingly. Likewise with the UI, colors and sizes which
work well on desktop often won't work very well on mobile/tablet
(especially if you are designing your desktop site mostly towards PC users,
due to the variations in color display).

There are tools out there now which allow you to package up your
HTML/JS/CSS/images into a native application bundle, meaning you don't have
to learn how to write native applications. There are a whole bunch of these
products out there [1], but most of them suck, here's why. Building a
client side JS application is *hard*, you have to understand the different
JS design patterns in order to write clean and stable code, whilst
understanding the importance of unit testing [3] and real browser testing
[4]. You also have to understand the impact of latency, if you don't
compile your assets into a local bundle (instead opting to just wrap a
browser window in an IOS app), then your app experience will lag between
clicks (because each click is a page load). To get around this you need to
build your client side app to be completely independent of the server side,
which includes maintaining a view state (e.g. changing/rendering the
display upon changes being made). Other libraries exist for doing this such
as Ember [5] and others, but they are still quite alpha and have
performance concerns too. Also in regards to bundling, there are very few
tools out there which will automate this entire process, for example
creating a spritesheet of UI images so you don't have to make multiple HTTP
asset requests, or embedding the images as base64 in your stylesheet
(although that has render performance concerns).

Then you also have the API, building a clean RESTful api is difficult and
in actual fact may be the wrong approach for your mobile app.. why? Because
each API call has a lot of overhead, and this usually results in UI latency
if the user has poor signal. There is some work being done to use
websockets instead of ajax calls, but this starts to get into quite deep
territory.

Gonna cut this short, as I try to limit myself to 30 minutes on any given
reply. Again don't worry too much about what I've put in the long answer,
that's just there to give you some insight into the things you'll start
thinking about as you get deeper into your journey.

Hope this helps dude

Beginner: Creating a form with variable number of checkboxes

[T Kwn]

I'm creating a page where the user can add other users to a group. I am 
able to dynamically fetch all users and list them on a template with 
checkboxes. I'm getting stuck creating a form for them however.

I read this post (among others)

http://stackoverflow.com/questions/19947538/django-form-with-unknown-number-of-checkbox-fields-and-multiple-actions

I don't understand what should be used to define "choices" in this example. 
He says fill it with a queryset but which one?

choices = queryset_of_valid_choices,

Would that be something like objects_list.all()?


Currently my form is defined as this:

class UpdateGroup(forms.Form):
non_member_checkboxes = forms.MultipleChoiceField(
widget  = forms.CheckboxSelectMultiple,
)

I know it's missing something because the form.is_valid is always False.

I'm guessing you should work around the problem by avoiding autofill for 
the moment and slugify in the model.save method.

Or maybe that library where field AutoSlug comes from isn't
compatible
with your version of Django?

 FK the UserProfile to those tables, not the other way around. That will 
leave them untouched/unmodified.

Look at the regex for the results path match, you have a lowercase ell 
where there should be a question mark.

As long as the class based view doesn't require you to be logged in you can
achive that by doing:

def dispatch(self, request, *args, **kwargs):
if not request.user.is_authenticated():
return HttpResponseRedirect(reverse("url_name_to_redirect_to"))

# Continue with other dispatch functionality

This has nothing to do with the decorator. You need to *call* the as_view

Well, this is a basic programming issue, and nothing to do with Python or 
Django.

Each time through your loop, you re-assign `tableC_QuerySet` to a new 
value. So, naturally, the value that it has at the end of the loop is 
whatever it had in the last iteration. If you want to get all the elements 
from each iteration, you'll need to put them into a list. For example:

values = []
for x in tableB_QuerySet:
values.extend(list(models.TableC.objects.filter(tableC_id = 
x.)))

In addition, there is almost certainly a more efficient way to do it, 
rather than doing a separate query for each tableB item, but without seeing 
more details of your models it's impossible to help further.

Re: Multiple levels of user in django application

[Anju SB]

We can't modify the 5 user details tables, because the other applications 
are associated with that table. It is required to map these table with user 
table.  But using the foreign key relationship we can only relate to one 
table. How can I design models without affecting the 5 tables mentioned.

ANN: eGenix mxODBC Connect 2.1.2 - Python Database Interface

[eGenix Team: M.-A. Lemburg]

ANNOUNCING
  eGenix.com mxODBC Connect

  Python Database Interface

Version 2.1.2


 mxODBC Connect is our commercially supported client-server product for
   connecting Python applications to relational databases
 in a truly platform independent way.


This announcement is also available on our web-site for online reading:
http://www.egenix.com/company/news/eGenix-mxODBC-Connect-2.1.2-GA.html


INTRODUCTION

The mxODBC Connect Database Interface for Python allows users to
easily connect Python applications to all major databases on the
market today in a highly portable, convenient and secure way.

Python Database Connectivity the Easy Way
-

Unlike our mxODBC Python extension, mxODBC Connect is designed as
client-server application, so you no longer need to find production
quality ODBC drivers for all the platforms you target with your Python
application.

Instead you use an easy to install royalty-free Python client library
which connects directly to the mxODBC Connect database server over the
network.

This makes mxODBC Connect a great basis for writing cross-platform
multi-tier database applications and utilities in Python, especially
if you run applications that need to communicate with databases such
as MS SQL Server and MS Access, Oracle Database, IBM DB2 and Informix,
Sybase ASE and Sybase Anywhere, MySQL, PostgreSQL, SAP MaxDB and many
more, that run on Windows or Linux machines.

Ideal for Database Driven Client Applications
-

By removing the need to install and configure ODBC drivers on the
client side and dealing with complicated network setups for each set
of drivers, mxODBC Connect greatly simplifies deployment of database
driven client applications, while at the same time making the network
communication between client and database server more efficient and
more secure.

For more information, please have a look at the mxODBC Connect product
page, in particular, the full list of available features.

For more information, please see the product page:

NEWS

mxODBC Connect 2.1.2 is a patch level release of our successful mxODBC
Connect product.

In the last patch level release 2.1.1, we had put a lot of emphasis on
enhancing the TLS/SSL setup of the mxODBC Connect product:

https://cms.egenix.com/company/news/eGenix-mxODBC-Connect-2.1.1-GA.html

In this release, we are fixing a pip installation problem, that
occurred with the mxODBC Connect Client on a few platforms, as well as
a some other minor issues we found:

Security Enhancements
-

 * OpenSSL cipher string list updated to explicitly disallow use of
   low security or export ciphers.

mxODBC Connect Enhancements
---

 * Fixed a problem that could cause the mxODBC Connect Client to not
   install correctly with pip.

 * Successfully tested against Python 2.7.9, which will come with a
   new ssl module.

 * Fixed the package version number to show the correct release
   version.

 * Fixed OpenSSL warnings in the Unix installer and scripts.

For the full set of changes, including those of the 2.1 series of
mxODBC Connect, please check the mxODBC Connect change log:
