Django 1.7 – makemigrations not detecting changes

As the title says, I can"t seem to get migrations working.

The app was originally under 1.6, so I understand that migrations won"t be there initially, and indeed if I run python manage.py migrate I get:

Operations to perform:
  Synchronize unmigrated apps: myapp
  Apply all migrations: admin, contenttypes, auth, sessions
Synchronizing apps without migrations:
  Creating tables...
  Installing custom SQL...
  Installing indexes...
Running migrations:
  No migrations to apply.

If I make a change to any models in myapp, it still says unmigrated, as expected.

But if I run python manage.py makemigrations myapp I get:

No changes detected in app "myapp"

Doesn"t seem to matter what or how I run the command, it"s never detecting the app as having changes, nor is it adding any migration files to the app.

Is there any way to force an app onto migrations and essentially say "This is my base to work with" or anything? Or am I missing something?

My database is a PostgreSQL one if that helps at all.

How can I make a time delay in Python?

5 answers

I would like to know how to put a time delay in a Python script.

Answer #1

import time
time.sleep(5)   # Delays for 5 seconds. You can also use a float value.

Here is another example where something is run approximately once a minute:

import time
while True:
    print("This prints once a minute.")
    time.sleep(60) # Delay for 1 minute (60 seconds).

Answer #2

You can use the sleep() function in the time module. It can take a float argument for sub-second resolution.

from time import sleep
sleep(0.1) # Time in seconds

Simply put and clear. Thank you for sharing. Django 1.7 – makemigrations not detecting changes and other issues with tty Python module was always my weak point 😁. Will get back tomorrow with feedback

tty Python module is always a bit confusing 😭 Django 1.7 – makemigrations not detecting changes is not the only problem I encountered. I just hope that will not emerge anymore

I was preparing for my coding interview, thanks for clarifying this - Django 1.7 – makemigrations not detecting changes in Python is not the simplest one. Will use it in my bachelor thesis
