# Migration `20201029214206-rejig-schema`

This migration has been generated by Kurt Hutten at 10/30/2020, 8:42:06 AM.
You can check out the [state of the schema](./schema.prisma) after the migration.

# explanation

The previous schema was really just thrown together to progress with parts of the client.
No relations had been included so this change in reality can be consider the initial schema.

## Database Steps

```sql
CREATE TABLE "PartReaction" (
    "emote" TEXT NOT NULL,
    "userId" TEXT NOT NULL,
    "partId" TEXT NOT NULL,
    "createdAt" DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP,
    "updatedAt" DATETIME NOT NULL,

    FOREIGN KEY ("userId") REFERENCES "User"("userName") ON DELETE CASCADE ON UPDATE CASCADE,
    FOREIGN KEY ("partId") REFERENCES "Part"("id") ON DELETE CASCADE ON UPDATE CASCADE
)

CREATE TABLE "Comment" (
    "id" TEXT NOT NULL,
    "text" TEXT NOT NULL,
    "createdAt" DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP,
    "updatedAt" DATETIME NOT NULL,

    FOREIGN KEY ("id") REFERENCES "User"("userName") ON DELETE CASCADE ON UPDATE CASCADE,
    FOREIGN KEY ("id") REFERENCES "Part"("id") ON DELETE CASCADE ON UPDATE CASCADE,
PRIMARY KEY ("id")
)

PRAGMA foreign_keys=OFF;
CREATE TABLE "new_Part" (
    "id" TEXT NOT NULL,
    "title" TEXT NOT NULL,
    "description" TEXT,
    "code" TEXT,
    "mainImage" TEXT,
    "createdAt" DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP,
    "updatedAt" DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP,
    "authorUserName" TEXT NOT NULL DEFAULT 'irevdev',

    FOREIGN KEY ("authorUserName") REFERENCES "User"("userName") ON DELETE CASCADE ON UPDATE CASCADE,
PRIMARY KEY ("title","authorUserName")
);
INSERT INTO "new_Part" ("id", "title", "description", "mainImage", "createdAt", "code") SELECT "id", "title", "description", "mainImage", "createdAt", "code" FROM "Part";
DROP TABLE "Part";
ALTER TABLE "new_Part" RENAME TO "Part";
CREATE UNIQUE INDEX "Part.id_unique" ON "Part"("id");
CREATE UNIQUE INDEX "Part.title_authorUserName_unique" ON "Part"("title", "authorUserName");
CREATE TABLE "new_User" (
    "userName" TEXT NOT NULL DEFAULT 'irevdev',
    "email" TEXT NOT NULL,
    "createdAt" DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP,
    "updatedAt" DATETIME NOT NULL,
    "image" TEXT,
    "bio" TEXT,
PRIMARY KEY ("userName")
);
INSERT INTO "new_User" ("email", "createdAt", "updatedAt", "image", "bio") SELECT "email", "createdAt", "updatedAt", "image", "bio" FROM "User";
DROP TABLE "User";
ALTER TABLE "new_User" RENAME TO "User";
CREATE UNIQUE INDEX "User.email_unique" ON "User"("email");
PRAGMA foreign_key_check;
PRAGMA foreign_keys=ON

CREATE UNIQUE INDEX "PartReaction.emote_userId_partId_unique" ON "PartReaction"("emote", "userId", "partId")

PRAGMA foreign_keys=off;
DROP TABLE "Post";
PRAGMA foreign_keys=on

PRAGMA foreign_keys=off;
DROP TABLE "Contact";
PRAGMA foreign_keys=on
```
