Failing to configure Django correctlly (conflict in settings between models.py and manage.py usage).

Hi, I'm new to Django and having some trouble to configure it. I'm using Django 1.11.9 (1.11.5 at first but then upgraded with hopes it will solve the issue) and Python 2.7.12 from virtualenv. Here is my project structure (Please pay attention to upper/lower case letters - it is intentionally):

You may not need Django for this. You could just use Flask e.g. https://pythonspot.com/flask-web-forms/ and https://stackoverflow.com/questions/27379486/retrieving-html-form-data-and-storing-in-csv-with-flask-python but, as with all web frameworks, you need to look at the fundamentals of how Fl

Hi Alex, You shouldn't have anything regarding the settings in models.py. Remove: import os import django os.environ["DJANGO_SETTINGS_MODULE"] = "MY_DJANGO.MY_DJANGO.settings" django.setup() from your models.py file. You should never have any settings in the models.py file at all. Also, you shou

Hi Andréas, Thanks for your response. When I'm removing the lines you've talked about I'm having the following error: django.core.exceptions.ImproperlyConfigured: Requested setting DEFAULT_INDEX_TABLESPACE, but settings are not configured. You must either define the environment variable DJANGO

Re: Failing to configure Django correctlly (conflict in settings between models.py and manage.py usage).

Ok, So are you in the folder where the manage.py file resides when you run your commands? You have to be in that directory when running manage.py commands. Also - as long as you haven't done too much already - I would recommend starting fresh and looking into the tutorials in the django docs page

Re: Failing to configure Django correctlly (conflict in settings between models.py and manage.py usage).

Here is what I've done so far (it is a new project and I did followed the tutorial until it didn't worked for me any more). Here are the steps of how I created the project: 1. django-admin startproject MY_DGANGO 2. python manage.py startapp my_django 3. edited the models.py 4. python manage

Re: Failing to configure Django correctlly (conflict in settings between models.py and manage.py usage).

Hi. You probably want to create Django management command to ease up all settings and such. For more information see https://docs.djangoproject.com/en/2.0/howto/custom-management-commands/

Re: Failing to configure Django correctlly (conflict in settings between models.py and manage.py usage).

Ah, OK. Now it is a bit more clear. What you are doing is not supported by django. You don't use the django models OUTSIDE of the django project. That is not a supported usecase. You can probably set it up, so that you CAN do that, but I would not recommend it. What are you trying to accomplish

Re: How to make a place where you could type in data(number)?

Hi, You definitely can use Django for that. If you want to learn how to do that you can start by doing Django tutorial [1] first to get hang of components and how things tie together in Django. If you feel that official tutorial is too packed, Django Girls do have very in depth and excellent tuto

Re: Failing to configure Django correctlly (conflict in settings between models.py and manage.py usage).

The only thing I need from Django (at this point) is to have the ability to communicate with my DB. (person = models.Person.objects.filter(phone_number= phone_number) from my previous example) I'm planning to use the admin page and I might add a GUI in some point. Regards, Alex On Friday, Janua

Re: Failing to configure Django correctlly (conflict in settings between models.py and manage.py usage).

Hi. That is a bit misleading information. It is completely supported using models (and other Django stuff) from standalone scripts wihtout using manage.py It's even documented at https://docs.djangoproject.com/en/2.0/topics/settings/ And specially part: https://docs.djangoproject.com/en/2.0/top

Re: Failing to configure Django correctlly (conflict in settings between models.py and manage.py usage).

Hi, As I did few posts already, you can do it few ways. I would recommend using custom management command. It will wrap up things nicely under Django hood, you don't need to figure out how to apply settings and such which allows you just need to concentrate to make your code to work. You can cre

Re: How do you check if a template is included into another?

Hi Luna, Why not do something like: Have a base template that you will use for the basic editing, let's call it `base_content_edit.html`: {% extends whatever-you-use-as-base-template %} {% block editor %} {% endblock %} and then, when you need a rich editor, you have a new template, say `ric
