# Data Modelling CLI Tool

## Requirements
This package requires Python >=3.8

## Installing
To install this CLI tool you can run the below command
```sh
$ pip3 install dm-cli
```

Alternatively, you clone this repo and then run this command from within the repository folder
```sh
$ pip3 install .
```

Both the above commands would install the package globally and `dm` will be available on your system.

## Usage

```sh
$ dm --help
Usage: python -m dm [OPTIONS] COMMAND [ARGS]...

Options:
  -t, --token TEXT  Token for authentication against DMSS.
  -u, --url TEXT    URL to the Data Modelling Storage Service (DMSS).
  -h, --help        Show this message and exit.

Commands:
  create-lookup  Create a named Ui-/StorageRecipe-lookup-table from all...
  ds     Subcommand for working with data sources
  init   Initialize the data sources and import all packages.
  pkg    Subcommand for working with packages
  reset  Reset all data sources (deletes and reuploads packages)
```

For each of the `commands` listed above, you can run `dm <COMMAND> --help` to see subcommand-specific help messages, e.g. `dm ds import --help` or `dm pkg --help`

### Expected directory structure
Certain commands expect a specific directory structure, such as the commands `dm reset`, `dm init`, and `dm ds reset`.
For these commands, the `path` argument must be the path to a directory with two subdirectories, `data_sources` and `data`.

```sh
$ tree app
app
├── data
│   └── DemoApplicationDataSource
│       ├── instances
│       │   └── demoApplication.json
│       └── models
│           └── DemoApplication.json
└── data_sources
    └── DemoApplicationDataSource.json
```

To add meta information to a package (for example to the models root package), a file with name "package.json" can be placed inside the folder.


### Supported reference syntax
The CLI tool will understand and resolve these kind of type reference schemas during import.
All values with one of these keys; `("type", "attributeType", "extends", "_blueprintPath_")` will be evaluated for resolution.

```bash
# URI - Full absolute path prefixed with protocol
dmss://datasource/package/entity
dmss://datasource/package/subfolder/entity

# Alias - Require dependencies to be defined somewhere in the source tree
ALIAS:packge/entity
ALIAS:entity

# Data Source - Relative from the destination data source
/package/entity
/package/subfolder/entity

# Package - Relative from the source package
entity
subfolder/entity

# Dotted - Relative from the file (UNIX directory traversal)
./../entity
../subfolder/entity
../../subfolder/entity
```

### General
Initialize the data sources

*i.e. import datasources and their packages*

```sh
$ dm init [<path>]
# By default, the `PATH` argument is set to the current working directory
$ dm init
# Optionally specify a path to the directory containing data sources and data
$ dm init app/
```

Reset all data sources

*i.e. delete all datasources and packages, before reuploading them*

```sh
# Reset all datasources and their packages
$ dm reset [<path>]
# By default, the `path` argument is set to the current working directory
$ dm reset
# Optionally specify a path to the directory containing data sources and data
$ dm reset app/
```

### Datasources
Import a datasource

```sh
# Import a datasource, where <path> is the path to a data source definition (JSON)
$ dm ds import <path>
$ dm ds import app/data_sources/DemoApplicationDataSource.json
```

Import all datasources

```sh
# Import all datasources found in the directory given by 'path'
$ dm ds import-all <path>
$ dm ds import-all app/data_sources
```

Reset a datasource

*i.e. reset the given data source, deleting all packages and reuploading them*

```sh
$ dm ds reset <data_source> [<path>]
# By default, the `path` argument is set to the current working directory
$ dm ds reset DemoApplicationDataSource
# Optionally specify a path to the directory containing data sources and data
$ dm ds reset DemoApplicationDataSource app/
```

### Packages
Import a package
> Note that importing a package will delete any preexisting package with the same name, if present in DMSS

```sh
# Import the package <path> to the given data source
$ dm pkg import <path> <data_source>
# Import the package 'models' from app/data/DemoApplicationDataSource'
$ dm pkg import app/data/DemoApplicationDataSource/models DemoApplicationDataSource
```

Import all packages

```sh
# Import all packages found in the directory given by <path>
$ dm pkg import-all <path> <data_source>
# Import all packages in 'app/data/DemoApplicationDataSource'
$ dm pkg import-all app/data/DemoApplicationDataSource DemoApplicationDataSource
```

Delete a package

```sh
# Delete the package from the datasource in DMSS
$ dm pkg delete <data_source> <package_name>
# Delete the package 'models' from 'DemoApplicationDataSource'
$ dm pkg delete DemoApplicationDataSource models
```

Delete all packages
> Note that this will only delete packages which are present in the directory <path>, so any package present in DMSS but absent in the given directory will not be removed.

```sh
# Delete all packages found in the directory given by <path>
$ dm pkg delete-all <data_source> <path>
$ dm pkg delete-all DemoApplicationDataSource app/data/DemoApplicationDataSource
```

### Recipe Lookup
Create a named Ui-/StorageRecipe Lookup table from a package. Tell DMSS to look through a package,
gather all RecipeLinks, and create a named lookup from that. The lookup can be used to associate recipes with an application.

```sh
dm create-lookup myApplicationName path/To/A/Package/With/RecipeLinks
```

## Development
> You need to have DMSS running locally.

```sh
$ python3 -m venv .venv
$ source .venv/bin/activate
$ pip3 install -e .
$ dm init
```

### Generating the DMSS API client
The DMSS API client, found in [`dm_cli/dmss_api/`](./dm_cli/dmss_api/), can be regenerated by running the script [`generate-dmss-api.sh`](./generate-dmss-api.sh). Note that an instance of DMSS must be running locally prior to executing the script.

```bash
./generate-dmss-api.sh
```

> NB: Due to incorrect import paths in the generated API client, you must do a search and replace after generating the new client. Replace all occurrences of '`from dmss_api`' with '`from dm_cli.dmss_api`' in all files under `dm_cli/dmss_api/`

### Testing

1. Install the dependencies: `pip3 install -r requirements.txt`
2. Install the dev dependencies: `pip3 install -r dev-requirements.txt`
3. Run the tests: `pytest`
