Re: Deciding on Database

2020-06-04 Thread RLM


Hello

I am a 25 year python dev working with Flask and Django experience and 
this is totally off topic but may I suggest you look at Hugo the static 
web site generator in the Go language.

It is easy to use, easier than some pythonic web site generators.

Easy to modify and update and is essentially ready to use and can be 
fully manipulated to do what you want. I used this system on AWS for a 
Australian national web site and find updating documents and comments is 
very simple, plus no one  can modify anything unless you grant express 
permissions. Plus you can decide whether it becomes public or private 
with the click of a checkbox.


Used in conjunction with AWS S3 buckets  it provides, for us, a very 
workable system. With AWS security the site is entirely safe.


My utmost apologies to the Python, Django community but sometimes other 
tools are worth looking at.

Hello everyone, Hope you are doing well.

I am building a website with django which will be used to view

The main viewer page will have a vertical nav bar with different 
chapters and sections. And the right side will be the content.


What I am trying to figure out is instead of doing a hardcoded HTML 
css static file, use the database to create a html file . What do you 
think is the best way to go about ir. I thought about it a lot and the 
problems I see is where there are lists/tables/images in content. I am 
having a hard time deciding what models should I create.

Re: open source advice needed

2020-02-06 Thread RLM

Hi Kimberley.
My daughter is a senior IT teacher in a school cluster of 4 schools. She
creates her learning, curriculum and tutorials on Moodle, she is very
good at using it.

She had much similar idea and concept as you describe below.
Being in Victoria Australia, the Education curriculum (IT) changes with
the wind so she uses tools the education department provides for. But
her preference is Moodle which her current school refuses to install.
I set up a server on AWS (Amazon Web Services) for her Moodle site and
the students found it easy to learn from. She found AWS more cost
effective that other ISPs.

Over the years we (she and I) have looked at a number of options but
Moodle has significantly matured and is a stand out system.

I hope this helps in some way.

Re: database migrations

2019-08-03 Thread RLM

Why try to avoid re populating the database? That's the easy part,
figuring what went wrong is more difficult.You don't need a lot of data
to get an app working, you just need to understand what you want and how
to achieve it.

When I was learning django I rebuilt my events database 20 times
sometimes using the original data and sometimes by starting afresh.
If you have valid working data consider writing the data tables to csv
then write that data into the new tables, it takes a couple of seconds
to recreate a table once you have the fields the same as the csv. I
found that when using a csv in spreadsheet it highlighted issues in the
data sets

When experimenting, I suggest use SQLite and simply rename the database
in the /dev app and start a new SQLite database by renaming it in the
config file. That way you have previous data and new data in the same
django application.

Also you could simply create new models in the current database and
repopulate only the fields you need in the new model.
In all the above the main trouble will be joins. Get one small fields
wrong and the join fails.

Cheers
Roger

Porting Django app

2019-05-16 Thread RLM

Hello all.
I eventually will need to put my dedicated Django app on another system
owned by a Public institution. The app correlates each data set of 26
million plus samples to a QR code for each.
Security is major so nothing can be web based, it must be in house and
disconnected from the external web.

A problem is I'm developing on Linux and Mac and much of the world uses
Windows 10 et al.

Installation of python3, Django, mysql and the app would rely on the IT
people at the institution who do not like installing software on secure
systems.
I would also point out that schools here also fall into the "will not
install that software" category significantly limiting student's ability
to learn modern systems.

I trialed compiling Python3 app to an .exe file, works ok, but am
concerned that P3/Django will not do so.

Bio: I'm in my 70's, been developing web apps for 25 years and do not
want to learn C and C++.

Can anyone advise me how to go about providing the system at minimum
problems for the IT sector of the institution.

Thanks in advance

Roger

Django issue with NoModuleError

2019-05-13 Thread RLM


Hi Everyone.
I have been away from Django for the past 18 months and am refreshing to 
use it for a complex samples storage project.


Python 3.7, Django 2.2 the LTS fails with too many errors.

Unfortunately I have had this particular error every time I try Django 
over the past 18 months which is why I had to resort to HuGo for a 
particular web site build.


I feel there is something I have forgotten to do and will appreciate 
help understanding why it occurs.


I have researched but no advice helps.
I have seen pages on PYTHONPATH and the like but problem is not solved 
and it seems to have been an issue for at least a year.


The project is called Storage, it's app is called samples.

The problem I have is the ModuleNotFoundError: No module named 'samples'.

Where samples is the only app.

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'samples',

root urls/py is:
urlpatterns = [
    path('admin/', admin.site.urls),
    path('samples/', include('samples.urls')),
]

samples/urls.py is:
from django.urls import path
from . import views

urlpatterns = [
    path('',views.index, name='index'),
]

There are no models.

samples/views.py is:
from django.shortcuts import render
from django.http import HttpResponse

def index(request):
    return HttpResponse("Hello from the RMH App")

Thanks for any help
Cheers

Re: Troubling installing Python 3 on my iMac

I guess you installed Python3.7.2 or similar

If so you can call it in a terminal with python3 not just python. Open a
terminal and type python3 it should start

python 7.n is the operating system version.
It is important to use pip3 and use virtualenv to create the python 3
environment.

use pip3 to install django in your environment.
When you look at tutorials in google or other specify python3 and >2018
so you don't get out of date tutorials of which there are hundreds.
