Hi, Michael--

Your doubt is justified. Just uploading the files is a bit of an
oversimplification. It would help if you gave some specifics about the
directory structure you're working with.

However, I can make a few general recommendations ...

1. Are you using version control? If not, you should - and it solves
part of your problem. I know it may seem like overkill to go through
all the steps of setting up a repo for just a little app, but if you
are at all serious about this Django development thing it will save
you a lot of work in the long run. I think these days Git is the most
popular version control system, but Mercurial (AKA hg) and Bazaar (AKA
bzr) are also very good (and both programmed in Python, yay!).

There is a good, concise tutorial online about setting up a Django
project to work with Git. I don't have a link for it, but I found it
very easily by Googling something like "Django version control."

So, assuming you have shell access (e.g., can log in via SSH) on your
web server, you would follow a procedure like this:

git push
DEV MACHINE --> GIT REPOSITORY

git pull
SERVER <--GIT REPOSITORY

That's *very* simplified. In reality, if you are trying to do
professional development, you need to at least have a test environment
online, so that you always test the code in conditions that are as
nearly identical as possible to your production server. But the above
will do if you're just experimenting. And if you don't have shell
access, someone else will have to help you with that.

Now, what files do you put under version control?

Let's say you follow the typical advice, and have a virtual
environment, with any Django projects/sites in separate directories.
For example, I'm using a setup like this (on Linux):

/srv/http/salixmedia.com/test/
pyenv/
[virtual environment with Django and other
required libraries]
my_site/
admin.py
settings.py
local_settings.py
models.py
wsgi.py

my_app/
admin.py
models.py
views.py

In this setup, all of 'my_app' would go under version control.
Likewise, all of 'my_site' *except* for local_settings.py - or
whichever file contains your secret keys and database password. You
need to guard that information closely, so it should never go into
version control.

Some people think you should put the virtual env (my 'pyenv'
directory) under version control too; I say no. You do want to ensure
that you have all the same libraries installed everywhere, but there's
another way to do that:

$ pip freeze > requirements.txt # on development box

$ pip install -r requirements.txt # on server

The requirements file lists all your installed packages, including
their versions. 'requirements.txt' should be under version control, so
you will have it on your server when you check out the code there. I'm
sure this approach is not totally foolproof, but I believe it is
fairly reliable, and will save you from cluttering your repo with a
great deal of third-party code that you will probably never modify.

Okay, so that takes care of all your python code and config files. You
also have to deal with your database. And honestly, I'm pretty new at
Django myself, and haven't completed figured out this aspect. When you
are setting up a site, you need to use commands such as

python manage.py syncdb

and

python manage.py migrate

If you're not familiar with those, I'd suggest you go through the
online documentation. These commands take care of your schemas (to
oversimplify, those represent your models in the database), but they
don't, by default, handle any site content that you may have created.
That's the part I'm not too sure about, but I'm sure others on this
list will have good advice.

Hope that helps a bit.

Re: How can I create models which only required during tests in Django 1.7c1?

Well as Yo-Yo Ma said, sometime the tests stand for testing django's inner 
working thus the real models are required.

For example this widget: http://i.imgur.com/ExaZt8l.png

And as you can see there are the history of previous inputs.

And i need to get rid of that.

Meaning: i don't want any history of previous inputs to be displayed.

Re: response to ajax (jquery) with variables

Hi again Antonio,

First of all, make sure you are using a good browser with debugging 
capabilities (I prefer Chrome), because you'll need it.


Secondly, I usually use the $.ajax request, instead of the post. 
Mainly because post is a wrapper around ajax and you can more finely 
change the settings of ajax.


So the post in your case would be:

$.ajax({
type: 'POST',   // Make sure you post
dataType: 'json',  // Use this so that you request json 
from the server

url: "/sitioweb/json/",
data: data,
success: function(data) {
// The data that is returned is your json data, already 
parser, so you don't have to parse it!
alert(data.array[0]); // Need to write "array" because 
that is what you are sending to the browser (your structure looks like 
that, check what the server is responding with)

},
error: function(xhr, textStatus, errorThrown) {
console.log('AJAX communication failed:', textStatus, 
errorThrown);// In case there is an error (for example a 500)

}
});

Now I can read data from  ajax to my def but I have not idea to
how send, for examle, an array to jquery and manage this from
javascript...

I tried:

def json_prueba(request):
arrg = [1,2,3,4]
if request.method == 'POST':
return HttpResponse(simplejson.dumps({'array': arrg}),
content_type="application/json")
return HttpResponse('FAIL!')

from the page side:

function updateDB(){
$.post("/sitioweb/json/", data, function(response){
if(response){
var data = JSON.parse(*response*); <- NOT
SURE IF THIS IS CORRECT
alert(data[0]); }  <- I´m trying
to put on an alert windows the first item of my array arrg
else{ alert('Error! :(');}
});
}

Hi Antonio,

That would do the trick. This is returned as JSON. Remember to
set the content_type, otherwise the client can get confused.

Hello,

i hope you can help me with this, I'm trying to send to an
ajax (jquery from my html template) a response but i would
like to send also a new variable.

in my html template I have:

$("#init_date").click(function(){
var some_date = {'init_date': init_date, 'end_date':
end_date};
$.post("/filter_dates/", some_date, function(response){
if(response === 'success'){
/MAKE SOMETHING//!!!/
else{ alert('error'); }
});
});

my django view look like:

def filter_date(request):
if request.method == 'POST':
example = ['A','B','C']
init_date = request.POST['init_date']
end_date = request.POST['end_date']
 MAKE SOMETHING!!
return HttpResponse('success') /AND HERE I WOULD LIKE
TO SEND THE example ARRAY.../
else:
return HttpResponse('error')

How can I send the array o some other variable as response?
