## Installation

## Documentation

### Quickstart

[A detailed example with best practices is given here.](doc-users.md)

### User guide

Note: the following user guide focuses on standard actions.

However, is often preferable to use shortcuts, when available, instead of standard actions. Many shortcuts are given in the quickstart example.

#### API documentation

To get a detailed documentation of the API, you may [directly connect to VBP backend](https://data.openergy.fr/api/v2) with your browser, log in, and navigate using the proposed links. On each page, you will find a ? on the upper right, you may click on it to view the documentation.

#### The client

The central object is the client. It contains: - the target url - the authentication credentials - a list of all available endpoints (see bellow, chapter endpoints) - shortcuts to access some records easily (get_organization, get_project, …)

To initialize, your must provide credentials :

Prepare auth file:

login password

Initialize client:

from ovbpclient import Client

# first method (see above for auth file content) client = Client(auth_path)

Instead of a path, you can give a buffer, which may be useful in some cases:

with open(auth_path) as f:

client = Client(f)

#### Endpoints

Endpoints are the entry points to resources (comparable to tables in a relational database). They are attached to the client. For example : - projects: client.projects - organizations: client.organizations - gates: client.gates - …

Each endpoint contains: - standard actions - shortcuts to easily perform custom actions (varies for each endpoint)

Standard endpoint actions:

list(start=0, limit=200, filter_by=None): returns a list of records (paginated).

Starting from {start} record, in the limit of {limit} (the backend paginates records). You may filter these records if you provide a dictionary {filter_by} (filter_variable=filter_value, …). Available filters are described in the backend API.

Example:

client.projects.list(filter_by=dict(organization=organization_id), limit=10)

iter(filter_by=None): return an iterator of record elements.

If you iter the reruned iterator, the client will automatically perform paginated querries until all the table has been exhausted. This may for example be usefull if you want to iter records until you find one matching a specific condition, then stop (which is more efficient than downloading all records). The filter system is available.

Example:

for project in client.projects.iter():

if “energy” in project.name:

break

list_all(filter_by=None): returns a list of all records.

The client performs multiple paginated requests, until all table has been exhausted. Should only be used when you known that there are not too many records. Filter system is available.

Example:

projects = client.projects.list_all(filter_by=dict(organization=organization_id))

create(**data): creates and returns a record.

You must provide data containing record info.

Example:

project = client.project.create(organization=organization_id, name=”project_name”, comment=”my comment”)

Note: it is easyier here to use the following shortcut: organization = client.get_organization(“organization_name”) project = organization.create_project(“project_name”, comment=”my comment”)

retrieve(record_id): retrieves a record.

You must provide record id.

Example:

project = client.project.retrieve(“project_id”)

Note: it may be easyier here to use a shortcut (although less efficient in terms of number of requests). organization = client.get_organization(“organization_name”) project = organization.get_project(“project_name”)

list_action(http_method, action_name, params=None, data=None, return_json=True, send_json=True): performs a custom action on enpoint

This is an expert use of client, normally using proposed shortcuts should be sufficient. The available list actions are given in the backend API documentation.

#### Records

Records are the objects that are returned by endpoints queries.

A record contains: - its data (stored in a dictionary: record.data). The content of this dictionary is also available using getattr syntax (project.name for example, instead of project.data[“name”]) - standard record actions - shortcuts

Standard record actions:

reload(): performs a request to reload data from api

Example: series.reload()

update(**data): updates record data

Example: project.update(comment=”new comment”)

delete(): deletes record

Example: unitcleaner.delete()

detail_action(http_method, action_name, params=None, data=None, return_json=True, send_json=True): performs a custom action on record

This is an expert use of client, normally using proposed shortcuts should be sufficient. The available detail actions are given in the backend API documentation.
