Django Model to Gorm Struct

Install using: pip install git+https://github.com/ranedk/djangorm Tool converts django models to Gorm struct

Usage

Put djangorm in INSTALLED_APPS

Then run python manage.py d2g --apps=<app-name> --lang=go Currently supports go and java

You can remove validation tags by using: python manage.py d2g --apps=<app-name> --lang=go --valid

You can remove gorm tags by using: python manage.py d2g --apps=<app-name> --lang=go --orm

You can remove gorm and validation by using: python manage.py d2g --apps=<app-name> --lang=go --orm --valid

e.g.

sampleproject/sampleapp/models.py

from django.db import models


class Author(models.Model):
    name = models.CharField(max_length=100, blank=True, null=True)
    email = models.EmailField()
    description = models.TextField()
    softcopy = models.FileField()
    softcopy_path = models.FilePathField()
    slug = models.SlugField()
    url = models.URLField()
    at_time = models.TimeField()
    uuid = models.UUIDField()

class AuthorProfile(models.Model):
    author = models.OneToOneField(Author, null=True, on_delete=models.SET_NULL)
    color = models.CharField(max_length=10, null=True)


class Book(models.Model):
    name = models.CharField(max_length=100, blank=True, null=True)
    email = models.CharField(max_length=100, unique=True)
    age = models.PositiveIntegerField(db_index=True)
    birthday = models.DateTimeField()
    member_number = models.CharField(max_length=100,null=True)
    activated_at = models.DateTimeField(null=True)
    created_at = models.DateTimeField()
    updated_at = models.DateTimeField()
    title = models.CharField(max_length=255)
    rating = models.IntegerField()
    author = models.ForeignKey(Author, on_delete=models.CASCADE)
    is_good = models.NullBooleanField()
    is_bad = models.BooleanField(default=True)


class Page(models.Model):
    book = models.ForeignKey(Book, null=True, on_delete=models.SET_NULL)
    number = models.IntegerField()
    authors = models.ManyToManyField(Author)

Running the command python manage.py d2g --apps=sampleapp --lang=go
