Re: Django production deployment on my VPS

hi Kamal,

I found this link as part of a django training I did in a udemy course (https://www.udemy.com/the-ultimate-beginners-guide-to-django-python-web-dev-website).

Link is:

https://www.digitalocean.com/community/tutorials/how-to-set-up-django-with-postgres-nginx-and-gunicorn-on-ubuntu-16-04

I hopes that helps you.

Gerardo.

Re: Database

Use whichever one you are more familiar with, unless there is a technical reason for your specific project to pick one over the other. Familiarity is important if you are just learning django, as you don't need too many learning curves at the same time. Sometimes, it is helpful to look at the tables that django creates to debug a problem. Knowing how to quickly access the db can be important. Or, sometimes injecting data into the db can help with debugging. At the end of the day, they are just tools, so use the one that you like the most. Personally, I prefer a left handed spanner the most....

Re: django windows apache tell if apache is working

I meant the tutorial at https://docs.djangoproject.com/en/2.0/intro/tutorial01/

That said, there's a few different ways you can actually deploy, but digitalocean has some good resources for starting out.

https://www.digitalocean.com/community/tutorials/how-to-serve-django-applications-with-apache-and-mod_wsgi-on-ubuntu-14-04

This one shows how to use apache on ubuntu, and you should be able to extrapolate to use wamp.

what I would do is just set up a simple view to return a http response saying "working", and map that to the root.  Something like 

app/views

def index(request):

    return HttpResponse("Working!")

app/urls

from app.views import index

urlpatterns = [

    path('', index), 

]

and hit localhost.  That'll be all you need.

Hi,

Thanks.

Yes, I went thru the Mozilla library tutorial on a fedora dev machine to the point where I realized I needed to do more with the last mile, so to speak working on setup of the production server part on Windows and wamp.

Seems most tuts end at manage.py runserver, or start into deployment from dev to production.  I can't seem to locate a good uptodate tut for wamp that shows how to test everything is working properly in a simple manner for the wsgi part.

I'm just trying to verify the plumbing (httpd.conf, settings.py wsgi.py) is working with apache, before spending too much more time building a site.

Re: Queryset calculation and then filter/exclude/limit data rendered

I figured it out.  Probably not the ideal solution, but it works for now.

I did not realize you could use an IF tag in the the template.  I then passed the fromDate and toDate into the template and used that to limit the records to only that particular month.

Hopefully as my skills increase I will find more elegant solutions.

I totally get what you are saying and thanks.  I tried a similar strategy.  I do qs = Check.objects.all()  and then I have to do the calculation as there is no balance in the model so I generate it on the fly in the for loop.  My hope was to then filter qs like you show.  It works, but my balance calculation is lost which is integral to the process.

my filter code looks like:

monthdata = check_list.filter(dater__gte=CalendarFromMonth, dater__lte=CalendarToMonth)

After some research that seemed like expected behavior where filter goes back thru the OCR where as I was hoping it would just filter on check_list and therefore retain the balance amount.

Thanks for your perspective, rod

Its not completely clear what you are doing.

You need to avoid logic in your template; but you say "excluding data from the the queryset in the for loop which is easy in other languages, but this also seemed to be a no go".  That is not the case if your logic is written in the correct way.

In my case I need to present a month-by-month view of orders; the UI displays day-by-day entries for the selected month (defaults to current month) with two "buttons" (hyperlinks) that are set to a +1 and -1 delta relative to the current month number so the user can jump back and forth easily.  The function in the views.py file accepts the month number as an argument and filters orders based on that month e.g. in your case you might do:

qs = Check.objects.all()

if selected_month:      qs = qs.filter(created__month=int(selected_month))

where selected_month would be a argument passed into your view.  You can then apply other calculation logic on the list.

I have a small checkbook application where I store transactions (expenses and income) amounts by date.  I render these to a template using python to add the cumulative balance prior to render.  This work fine for my little application, but not too sure how scalable it will be over time.

My goal is to have this displayed by month with the running balance.  I first researched custom pagination, but found nothing on date pagination by month and year.  I then started down the road of excluding data from the the queryset in the for loop which is easy in other languages, but this also seemed to be a no go.  My current thought is to exclude the data from the queryset in the for loop and move the data into a dictionary or list, or json.

Any advice for me?  Right now I need all objects from the Check model to get an accurate balance and then I need to filter that to limit the records by month.

Finally, I did tried to filter the check_list after the balance was added, but found out that does not work as the query goes back to the model and I loose the balance.

Here is my model

class Check(models.Model):

    """

    Model representing a checkbook transaction.

    """

    check_type = (('CR', 'credit'),('DR', 'debit'),('SV', 'savings'),('DT', 'debt reduction'),)

    

    dater = models.DateField(help_text=' .the date of the transaction')

    type = models.CharField(max_length=2, choices=check_type, help_text=' .credit or debit')

    category = models.ForeignKey('Category', on_delete=models.SET_NULL, null=True)

    name = models.CharField(max_length=100, help_text=' .description')

    amount = models.IntegerField(default=0, help_text=' .amount')

    cleared = models.BooleanField(help_text=' .cleared with the bank?')

    created = models.DateTimeField(auto_now_add=True)

Here is my function view

def checkbookList(request):

    check_list = Check.objects.all()

    #checks = Check.objects.all()

   

    balance = 0

    #for chk in checks:

    for chk in check_list:

        balance += chk.amount

        chk.balance = balance

        if chk.cleared:

            chk.cleared = '\u221A'

        else:

            chk.cleared = '-'

    return render(request, 'checkbook/checkbook.html', {'checks': check_list})

Re: Can't access my django runserver

you're missing a comma at the end of 

 'DIRS': [os.path.join(BASE_DIR, 'templates')]

for future reference, if you want people to help you, give the information up front as well as context.  Your original posting showed minimal information, so there was nothing we could do until you posted the above.

You should also be using a text editor like atom, sublime, vscode, etc with a graphical linter so you can see syntax errors like the above more easily.

Re: Can't access my django runserver

You forgot to put 'comma' after DIRS': [os.path.join(BASE_DIR, 'templates')] in templates.

It should be DIRS': [os.path.join(BASE_DIR, 'templates')],

django windows apache tell if apache is working

Hi,

I'm new to this group, and also new to Python, and Django.  Seems like lots of good info for django on this group.

Sorry for long, detailed descriptions, below, but I am stuck trying to verify wamp, apache and django are working as a production server on a Windows 7, 32-bit machine.

I am hung on last mile part (way below), or how to see something in the browser using apache, not the dev runserver.  The dev server seems to work fine at this point showing default django startup page.

I'm not sure how to proceed with verifying apache is working as a production server.  If all is working, should apache show the same Python default start page as the dev server?  Or what simple web pages should I implement to verify the apache connection is actually working on the server?

Wamp is also working fine with it's own www directory and local webpages etc. using apache.

Wampserver 3.0.6 32bit, with apache2.4.23

---------------

PYTHON AND APACHE:

Python 3.6.5 32bit, with Django 2.0.6

Tried following Eastwood description for Django setup for Wamp

https://ericeastwood.com/blog/3/django-setup-for-wamp

---------------

MOD_WSGI:

Could not pip install mod_wsgi, and needed to download VisualStudio build tools and upgrade framework to 4.7.1.

Downloaded mod_wsgi-4.5.24+ap24vc14-cp36-cp36m-win32.whl

https://www.lfd.uci.edu/~gohlke/pythonlibs/

to work with apache 2.4.23, VC++14, and python3.6

then did >> pip install C:\Users\Administrator\Downloads\mod_wsgi-4.5.24+ap24vc14-cp36-cp36m-win32.whl.  Did not get mod_wsgi.so in apache modules folder, but did get a .pyd in: c:/users/administrator/appdata/local/programs/python/python36-32/lib/site-packages/mod_wsgi/server/mod_wsgi.cp36-win32.pyd

Could then run mod_wsgi-express.

From cmd prompt in apache bin dir used >httpd -t -D DUMP_MODULES to show wsgi_module (shared) is present.

---------------

VIRTUALENV:

Per Eastwood description (above), inside c:/wamp created a new directory www-src next to www which is where our other wamp sites are located. Inside c:\wamp\www-src ran >virtualenv django_project, then django_project\Scripts\activate.  See (django_project) as prefix to cmd prompt. With virtual environment active did >pip install django.  Then (django_project_ c:\wamp\www-src > django-admin.py startproject django_project .  to setup up project in current or www-src directory.

c:\wamp\www-src\django_project

c:\wamp\www-src\static

c:\wamp\www-src\db.sqlite3

c:\wamp\www-src\manage.py

and in c:\wamp\www-src\django_project have settings.py, urls.py, and wsgi.py, etc.

---------------

SETTINGS.PY

in settings.py change STATIC_URL to:

STATIC_ROOT = 'C:/wamp/www-src/static'

STATIC_URL = 'http://XXXmyipXXX/static/'

also added localhost, and my local IP to ALLOWED_HOSTS in settings.py

---------------

MIGRATIONS:

then from c:\wamp\www-src run

(django_project) c:\wamp\www-src >manage.py makemigrations

then

(django_project) c:\wamp\www-src >manage.py migrate

also ran >(django_project) c:\wamp\www-src >manage.py collectstatic

although static dir is empty at this point.

---------------

DEVELOPMENT SERVER:

(django_project) c:\wamp\www-src >manage.py runserver 0.0.0.0:8000

From the browser > http://localhost:8000 this initially caused windows firewall error to appear but an exception was added to allow it to continue.

Can see python default page, and also localhost:8000\admin too on Dev server.  Dev server can be seen by other machines on the network too.

----------------

CONFIGURE APACHE:

for production server using wamp instead of dev server.

using mod_wsgi-express settings in httpd.conf.

Apache httpd.conf is in:

C:\wamp\bin\apache\apache2.4.23\conf\httpd.conf

Apache httpd-vhosts.conf is in:

C:\wamp\bin\apache\apache2.4.23\conf\extra\httpd-vhosts.conf

added to httpd.conf:

LoadFile "c:/users/administrator/appdata/local/programs/python/python36-32/python36.dll"

LoadModule wsgi_module "c:/users/administrator/appdata/local/programs/python/python36-32/lib/site-packages/mod_wsgi/server/mod_wsgi.cp36-win32.pyd"

WSGIPythonHome "c:/users/administrator/appdata/local/programs/python/python36-32"

WSGIScriptAlias /django-project "C:/wamp/www-src/django_project/wsgi.py:C:/wamp/www-src/django_project/wsgi_app.py"

WSGIPythonPath "C:/wamp/www-src/django_project/:C:/wamp/www-src/django_project/Lib/site-packages"

<Directory "C:/wamp/www-src/django_project/">

    <Files wsgi.py>

        Order deny,allow

        Require all granted

    </Files>

    <Files wsgi_app.py>

        Order deny,allow

        Require all granted

    </Files>

</Directory>

added to httpd-vhosts.conf:

<VirtualHost *:80>

Alias /static c:/wamp/www-src/static

<Directory c:/wamp/www-src/static>

        Require all granted

    </Directory>

</VirtualHost>

...restarted apache

----------------------------

CONFUSED FROM HERE...or last mile to verify production server can run django from virtual environment.

If try localhost:8000 in browser see ERR_CONNECTION_REFUSED.

If try localhost/wsgi and have wsgi_app.py in django_project, see requested URL not found.

wsgi_app.py

def application(environ, start_response):

    status = '200 OK'

    output = 'Hello World from django_project!'

    response_headers = [('Content-type', 'text/plain'),

                        ('Content-Length', str(len(output)))]

    start_response(status, response_headers)

    return [output]

Re: Django Admin

Teja,

First, let me suggest you just copy and paste your models from models.py. People who use Django a lot may find it easier to read the code (because they are familiar with the syntax and layout) than your typed summary of the classes.

Second, Django by itself cannot do what you want it to do. Django just makes html pages from the models, views, and templates you define, or are found in the admin classes. Once a page is displayed, that is what you get until the page is re-loaded from the server. What you are trying to do is have the page change without a round trip to the server. For that, you need some form of Javascript talking to the server as well. You can change the contents of an html page based on a selection in a select box using some Javascript to detect the change in the page and then talks to a Django view; the view in Django gets the data you want from the database and returns that data to the script, which updates the html page; and an appropriate url for the script to talk to the view and for the view to listen to. That is just one way to accomplish what you want to do. There are also add-on django projectst that will do this for you. Google for django smart selects, django autocomplete, django ajax, and this page of projects - https://djangopackages.org/grids/g/auto-complete/.

Good luck!

Hi Team,

Company Model has : CMP1, CMP2, CMP3, CMP4, CMP5(Year is the foreign key in this model)

Department Model has : DEP1, DEP2,DEP3,DEP4,DEP5 (Company is the foreign key in this model)

Section Model has : SEC1, SEC2,SEC3,SEC4,SEC5 (Department is the foreign key in this model)

Employee Model has : EMP1,EMP2,EMP3,EMP4,EMP5 (Section is the foreign key in this model)

Now I have created 2 more models (class Details, Class Map)

Details Model Fields:

salary

Map Model Fields : 

Company ( foreign key Company Model)

Department (foreign key Department Model )

Section (foreign key section Model)

Employee (foreign key employee Model)

Details Model will Map salary for the employees

I need to show these two models in admin page ( class Map as the inline model for class Details)

=================================================================================

ADMIN PAGE looks as below :

Details 

select salary range

 (drop down)

MAP [ inline Model ] : Need to Map employees who come under the salary range

1.  select Company      select Department        select Section       select Employee
   

           (drop down)              (drop down)                   (drop down)           (drop down)

     2. select Company      select Department        select Section       select Employee

           (drop down)              (drop down)                   (drop down)           (drop down)

     3. select Company      select Department        select Section       select Employee

           (drop down)              (drop down)                   (drop down)           (drop down)

======================================================================================

=> On selecting a company, we should display only departments in that company.

=> On selecting Department, we should display only sections in that Department.

=> On selecting Section, we should display only employees in that Section.

 

I am messed with this implementation, Please help me out in this. If possible please brief me the steps to follow on this implementation

Thanks in Advance
