Accessing and Manipulating Records
All content that is stored in Engine is stored in the form of records. This includes flow scripts, files, messages, users, executions and anything else you or the system create on the platform. All records can be accessed and manipulated with the same methods.
This section describes three methods for creating, accessing, manipulating, and deleting records. More detailed information can be found in the REST API documentation, and the Flow-API documentation.
Creating
Via the User Interface
- Press "+ Create" and select the type of record you like to create.
The create button
- The new record is opened in the main section.
Via the REST API
Send a POST
request to:
https://<your-workspace-name>.cloudomation.com/api/latest/<record-type>
The JSON payload should contain all fields you wish to set.
Via the Engine Flow-API
import flow_api
def handler(system: flow_api.System, this: flow_api.Execution, inputs: dict):
system.<record-type>('name of the new record').save()
# for example:
system.setting('my-new-setting').save()
# you can set fields of the new record:
system.setting('my-new-setting').save(value=42, description='some number')
Please note, that .save()
is necessary for the record to be created.
The save
method overwrites existing records with the same name and type, unless they're read-only. If that is not intended, you can first check for the existence
of a record with the same name and type, before calling the save
method.
Engine resource names must not start or end with a blank. Engine will implicitly remove any leading or trailing blanks from resource names.
Listing
Via the User Interface
- Switch to the workspace dashboard by clicking the Engine logo in the menu.
- Scroll down to the resource tabs.
Via the REST API
Send a GET
request to:
$ curl https://\<your-workspace-name>.cloudomation.com/api/latest/\<record-type>
You can use filter expressions:
$ curl 'https://\<your-workspace-name>.cloudomation.com/api/latest/\<record-type>?filter={"field":"name","op":"like","value":"my-%"}'
Via the Engine Flow-API
Listing via the Flow-API will return all records which exist when the listing starts. This means when records are created during the listing, they will not be included in a currently running listing. Also, when records are deleted during the listing, they are still returned. Make sure to handle the ResourceNotFoundError
while iterating over a listing result.
Use the following method:
import flow_api
def handler(system: flow_api.System, this: flow_api.Execution, inputs: dict):
# for record in system.<record-type>s():
# # do something with "record"
# for example:
this.log(all_webhooks=list(system.webhooks()))
# you can use filter expressions
this.log(all_enabled_webhooks=list(system.webhooks(filter_={
'field': 'is_enabled',
'op': 'eq',
'value': 'True',
})))
The maximum number of records that are returned with one call is 1000. Therefore, if you have more than 1000 records of a specific record type
you need to use multiple iterations combined with offset
and order
to list all records.
The parameters for system.<record-type>s
are as follows:
Parameter | Description | Default value |
---|---|---|
fields | Which fields to return (string of comma-separated field-names). | None |
limit | How many records to return. | 1000 |
offset | How many records to skip before returning records. | 0 |
filter_ | Filter to limit the results. | None |
order | How to order the records before applying limit and offset (string of comma-separated field-names). | None |
allow_normal | If to include normal records in the response (That is records which are not deleted). | True |
allow_deleted | If to include deleted records in the response. | False |
filter_
The filter can either be a basic filter, consisting of 3 key-value pairs:
field
: the field to match againstop
: the operation used for matching, possible values: eq, neq, like, notlike, lt, gt, lte, gte, set, unset, in, notinvalue
: match to this value, mutually exclusive withvalue_field
value_field
: match the field of this record, mutually exclusive withvalue
A value still needs to be specified when using the set
or unset
operation, even though it has no effect.
The field
can map to other records. The following syntax is used to map to another record:
<own field>--<other record>.<join field>:<filter field>
or it can contain a collection of filters using the and
or or
key:
and
: every filter provided in the list must beTrue
or
: at least one filter provided in the list must beTrue
Filter resources which were created by either of the two identities, given their name. Be aware that multiple identities can share the same name (executions for example) and that thus this example might include more records than anticipated.
{
"or": [
{
"field": "created_by--identity.id:name",
"op": "eq",
"value": "some-user"
},
{
"field": "created_by--identity.id:name",
"op": "eq",
"value": "some-other-user"
}
]
}
The previous example could also be rewritten using the in
operation:
{
{
"field": "created_by--identity.id:name",
"op": "in",
"value": ["some-user", "some-other-user"]
},
}
Reading
Via the User Interface
- Enter the name or parts of the name of the record in the quick search bar.
- Click on the record in the quick search results.
- The record is opened in the main section.
Via the REST API
Send a GET
request to
https://<your-workspace-name>.cloudomation.com/api/latest/<record-type>/<record-id>
You can also access resources by name:
Send a GET
request to:
https://<your-workspace-name>.cloudomation.com/api/latest/<resource-type>/<resource-name>?by=name
See the records reference to learn about the different resources and activities
You can specify the fields you are interested in:
https://<your-workspace-name>.cloudomation.com/api/latest/<record-type>/<record-id>?fields=id,name,description
Via the Engine Flow API
Use the following method:
import flow_api
def handler(system: flow_api.System, this: flow_api.Execution, inputs: dict):
system.<record-type>('name of the record').get('name of field to read')
# for example:
description = system.flow('my-flow').get('description')
# you can read several fields at once:
created_at, modified_at = system.flow('my-flow').get('created_at', 'modified_at')
Updating
Via the User Interface
- Open the record you want to modify.
- Change any field of the record.
- Press the "save" button.
Via the REST API
Send a PATCH
request to:
https://<your-workspace-name>.cloudomation.com/api/latest/<record-type>/<record-id>
The JSON payload should contain all fields you wish to update.
Via the Engine Flow API
Use the following method:
import flow_api
def handler(system: flow_api.System, this: flow_api.Execution, inputs: dict):
system.user('<my-user-name>').save(description='This is me')
Deleting
Refer to Trash (deleted records) for information on how to move to trash, permanently delete and restore records.
