You'll need to use some undocumented APIs for this, but here's one way:
from django.db
import connections
from django.db.migrations.loader
import MigrationLoader
loader = MigrationLoader(connections['default'])
loader.load_disk()
If you want only the ones that have been applied:
from django.db.migrations.recorder

One notable example where customizing migrations is required is when renaming a property. For example, if you rename a property from Name
to FullName
, EF Core will generate the following migration:
migrationBuilder.DropColumn(
name: "Name",
table: "Customers");
migrationBuilder.AddColumn<string>(
name: "FullName",
table: "Customers",
nullable: true);
EF Core is generally unable to know when the intention is to drop a column and create a new one (two separate changes), and when a column should be renamed. If the above migration is applied as-is, all your customer names will be lost. To rename a column, replace the above generated migration with the following:
migrationBuilder.RenameColumn(
name: "Name",
table: "Customers",
newName: "FullName");
dotnet ef migrations remove
If you want to learn a lot about how migrations work internally, and how Django figures out what migrations you have and which are applied, check out the source code of the manage.py migrate command.,I had run makemigrations and after that migrate to apply the migration,How to find out models in boards from command line?,After this, loader.disk_migrations will be a dictionary whose keys are (app_name, migration_name) tuples, and whose values are the Migration objects. So iterating loader.disk_migrations.keys() will give you a list close to what you want, and you can just format it as desired.

01 How to list applied migrations from command line? ,If you want to learn a lot about how migrations work internally, and how Django figures out what migrations you have and which are applied, check out the source code of the manage.py migrate command.,Python is one of the programming languages with wide range of uses especially among scientific computations, machine learning, data science, web application development and many other fields. It's also one of the most in-demand languages out there. In this post you'll find answers to common python language queries that arise while working with python code.,After this, loader.disk_migrations will be a dictionary whose keys are (app_name, migration_name) tuples, and whose values are the Migration objects. So iterating loader.disk_migrations.keys() will give you a list close to what you want, and you can just format it as desired.
You'll need to use some undocumented APIs for this, but here's one way:

The resulting file will be named migration-list and will be placed in the /usr/local/psa/var/modules/panel-migrator/sessions/migration-session/ directory. The migration list is a list of objects (customer and reseller accounts, service plans, domains, and so on) to be migrated., Run the following command to begin the migration: /usr/local/psa/admin/sbin/modules/panel-migrator/plesk-migrator transfer-accounts ,The resulting file will be named migration-list and placed in the <PLESK_DATA_DIRECTORY>\var\modules\panel-migrator\sessions\migration-session\ directory.

The Flyway command-line tool is a standalone Flyway distribution. It runs on Windows, macOS and Linux and it is primarily meant for users who wish to migrate their database from the command-line without having to integrate Flyway into their applications nor having to install a build tool.,The Flyway Command-line tool distribution ships with all editions of Flyway. It auto-detects which edition to run based on any license keys you configure, however it can easily be configured to run the paid editions specifically.,The Flyway command-line tool has been carefully designed to load and override configuration in a sensible order.,It is also possible to point Flyway at one or more additional config files. This is achieved by supplying the command line parameter -configFiles= as follows:
Linux
$ wget - qO - https: //repo1.maven.org/maven2/org/flywaydb/flyway-commandline/9.1.2/flyway-commandline-9.1.2-linux-x64.tar.gz | tar xvz && sudo ln -s `pwd`/flyway-9.1.2/flyway /usr/local/bin
Docker
$ sudo sh - c 'echo "docker run --rm flyway/flyway:9.1.2 $*" > /usr/local/bin/flyway && chmod +x /usr/local/bin/flyway'
$ sudo sh -c 'echo "docker run --rm flyway/flyway:9.1.2 $*" > /usr/local/bin/flyway && chmod +x /usr/local/bin/flyway'
> docker pull flyway / flyway: 9.1 .2
Linux
$ wget - qO - https: //download.red-gate.com/maven/release/org/flywaydb/enterprise/flyway-commandline/9.1.2/flyway-commandline-9.1.2-linux-x64.tar.gz | tar xvz && sudo ln -s `pwd`/flyway-9.1.2/flyway /usr/local/bin

$ sudo sh - c 'echo "docker run --rm redgate/flyway:9.1.2 $*" > /usr/local/bin/flyway && chmod +x /usr/local/bin/flyway'
$ sudo sh -c 'echo "docker run --rm redgate/flyway:9.1.2 $*" > /usr/local/bin/flyway && chmod +x /usr/local/bin/flyway'

> docker pull flyway / flyway: 9.1 .2
The Flyway download, once extracted, now becomes a directory with the following structure:
flyway - 9.1 .2
conf
flyway.conf configuration file
drivers JDBC drivers
jars Java - based migrations(as jars)
jre
lib
licenses
sql SQL migrations
