Does Django detect changes in models Meta ?

[termopro]

Hi there,

I am using Django 1.7 RC2.
I have created models and have run all the migrations so Django created 
tables in database.
Now i decided to change database table names and have added Meta class to 
models containing table name:

class SomeModel(models.Model):
   ...
   class Meta:
  db_table = 'newname'

Now when i run "makemigrations" Django doesn't detect any changes in models:
"No changes detected in app 'blabla'."
As far as i understand the logic, Django should change table names from 
'appname_somemodel" to "newname".

Is this an expected behavior or i am missing something?

Creating a QuerySet where the presence of a row is dependent on other rows in the result

[Dave Cole]

I have a problem where I need to define a QuerySet where the conditions for 
including one row depend on evaluating values in one or more other rows in 
the QuerySet.

Is there a way to manually construct a QuerySet by iterating over rows from 
another QuerySet and individually adding them to the new QuerySet?

Re: Does Django detect changes in models Meta ?

[Norman Bird]

I am new, just completed the tutorials, but from my understanding you run 
"python manage.py syncdb" and that rebuilds the tables etc.

Re: Handling temporary file storage with WizardView

[zubair alam]

although this post older, you might have found a solution for your

I think if file path is set to something where you want to save it finally 
would be much better than cleaning tmp directory.
destination folder can be specified to FileSystemStorage

No, syncdb only create tables that do not exist. It does not alter any
existing tables.

First app using mouse click event

[ASHISH KUMAR GUPTA]

Hi,

I am very new to web development and started learning django few days back 
as I really like and enjoy Python. I have done the first tutorial and I 
understand some of the basic concepts. I want to develop an app where I 
need to record mouse clicks from the user, can someone please guide me to a 
simple example which can explain how to do this?

Many thanks,
Ashish

Re: Comments in real time

If you need to save the comments, take a look to django-angular.
Its an integration of angularJS into django.
Where you can save the model via javascript, i really recommend you Angular for 
this.

trouble logging in to post ticket for django documentation

[Steve]

Total noob here.  I'm working through the (very helpful) django tutorials. 
 I'd like to enter a suggestion ticket.  I've created a github account and 
logged into it, yet I still receive the following error message from 
code.djangoproject.com:

You are currently not logged in. You may want to do so 
 now.
Error: Forbidden

TICKET_CREATE privileges are required to perform this operation. You don't 
have the required permissions.

I try to login again via the "do so" link above; I enter my new github 
username and password but instead of logging in I'm stuck in an infinite 
loop whereby I'm asked for my login credentials forever.  What gives? 
 Cheers.

Preparing virtualenvwrapper for Django 1.6 development

[Sithembewena Lloyd Dube]

Hi everyone,

I am developing on a Windows 8.1 machine and wold like to setup
virtualenvironment via virtualenvwrapper so as to have a properly set up
Python development environment.

I am referring to Jeff Knupp's guide at
http://www.jeffknupp.com/blog/2013/12/18/starting-a-django-16-project-the-right-way/

After installation of virtualenvwrapper via pip, the guide says:
"
After it's installed, add the following lines to your shell's start-up file
(.zshrc, .bashrc, .profile, etc).

export WORKON_HOME=$HOME/.virtualenvs
export PROJECT_HOME=$HOME/directory-you-do-development-in
source /usr/local/bin/virtualenvwrapper.sh
"

My issue is, I do not understand what these lines are doing (I have a vague
idea but assumptions can be deadly). Moreover, it is clear that the
instructions were authored with a UNIX environment in mind.

Would anyone be so kind as to translate this to Windows speak, as well as
perhaps pointing out what file this would go into in a Windows environment?

Thanks in advance :)

Kind regards,
Sithu.

How to set response headers in DetailView

[Lucas Simon Rodrigues Magalhaes]

Hello,

I see this tutorial [1] to control the response header and caching of pages 
in django. 

So I'm trying to enable this response header in a generic class DetailView. 
I did a search and found this code [2] at the end of the page and also the 
source code [3] of View. 

But are confused and do not know about which method to override correctly. 
Does anyone have any tips or example to send me?

Re: Creating a QuerySet where the presence of a row is dependent on other rows in the result

No. At it's core, QuerySet is a wrapper around a relational database, and a
relational database uses relational algebra to do what it does. That isn't
an iterative activity. If you can't express membership of a queryset as a
set of conditions on a single row (where that single row might involve
joins on other tables, including itself).

However, you *can* iterate over the results of a queryset. Get an initial
candidate set via filter(), then iterate over the results to generate
(either by removing unwanted elements, or selecting and inserting elements)
a final result set. The output of this process won't be a queryset, but it
will be an iterable, and in many cases that will be enough.

Yours,
Russ Magee %-)

Thanks Russ.  Everything's peachy.

I poked around enough before posting my message that I ought have put that 
together myself.  Sorry to have bothered you.  Cheers.

Re: Preparing virtualenvwrapper for Django 1.6 development

[Mike Dewhirst]

On 23/08/2014 7:23 AM, Sithembewena Lloyd Dube wrote:

Hi everyone,

I am developing on a Windows 8.1 machine and wold like to setup
virtualenvironment via virtualenvwrapper so as to have a properly set up
Python development environment.

I am referring to Jeff Knupp's guide atÂ
http://www.jeffknupp.com/blog/2013/12/18/starting-a-django-16-project-the-right-way/

After installation of virtualenvwrapper via pip,


I'm not sure this gives you the windows version. I don't use it on 
Windows 8.1. I somehow thought it wasn't available for Windows and wrote 
my own set of batch files instead. But it appears there is a 
virtualenv-win ...


https://github.com/davidmarble/virtualenvwrapper-win

... in which it appears there is a powershell caveat - which is a 
mystery to me.


Good luck

Mike

the guide says:

"
After it's installed, add the following lines to your shell's start-up
file (.zshrc, .bashrc, .profile, etc).

export WORKON_HOME=$HOME/.virtualenvs
export PROJECT_HOME=$HOME/directory-you-do-development-in
source /usr/local/bin/virtualenvwrapper.sh
"

My issue is, I do not understand what these lines are doing (I have a
vague idea but assumptions can be deadly). Moreover, it is clear that
the instructions were authored with a UNIX environment in mind.

Would anyone be so kind as to translate this to Windows speak, as well
as perhaps pointing out what file this would go into in a Windows
environment?

Thanks in advance :)

Kind regards,
Sithu.
