Use the RequestOptions
object to define filtering and sorting criteria for an endpoint, then pass the object to your endpoint as a parameter.
You can use the TSC library to filter and sort the following endpoints:
For the above endpoints, you can filter or sort on the following fields:
Important: Not all of the fields are available for all endpoints. For more information, see the REST API help.
FilteringTo filter on a field, you need to specify the field name, an operator criteria and a value criteria.
Note: Ampersands and commas in filters are not supported by the REST API as they are used as delimiters.
Operator criteriaThe operator that you want to use for that field. For example, you can use the Equals operator to get everything from the endpoint that matches exactly.
The operator can be any of the following:
The value that you want to filter on. This can be any valid string.
Filtering example - RequestOptionsThe following code displays only the workbooks where the name equals Superstore:
req_option = TSC.RequestOptions()
req_option.filter.add(TSC.Filter(TSC.RequestOptions.Field.Name,
TSC.RequestOptions.Operator.Equals,
'Superstore'))
matching_workbooks, pagination_item = server.workbooks.get(req_option)
print(matching_workbooks[0].owner_id)
Sorting
To sort on a field, you need to specify the field name and the direction criteria for the sort order.
Direction criteria - RequestOptionsThis can be either Asc
for ascending or Desc
for descending.
The following code sorts the workbooks in ascending order:
req_option = TSC.RequestOptions()
req_option.sort.add(TSC.Sort(TSC.RequestOptions.Field.Name,
TSC.RequestOptions.Direction.Asc))
matching_workbooks, pagination_item = server.workbooks.get(req_option)
for wb in matching_workbooks:
print(wb.name)
Django style filters and sorts Filtering examples - Django style
The following code displays only workbooks where the name equals Superstore:
all_workbooks = server.workbooks.filter(name='Superstore')
for workbook in all_workbooks:
print(workbook.owner_id)
Setting page size
Starting with version 0.32, you can set the page size for the request by using the page_size
keyword argument. The default page size is 100 if not provided.
superstore_workbooks = server.workbooks.filter(name='Superstore', page_size=10)
# or
all_workbooks = server.workbooks.all(page_size=1000)
Direction criteria - Django style
The field name can be input as normal for ascending or prefixed with -
for descending.
The following code sorts the workbooks in ascending order:
matching_workbooks = server.workbooks.order_by('name')
for wb in matching_workbooks:
print(wb.name)
Sort can take multiple args, with desc direction added as a (-) prefix
workbooks = workbooks.order_by("project_name", "-created_at")
Indexing and slicing
Querysets can be indexed and sliced like a list. The query is executed at when the queryset is indexed or sliced.
# Get the first item in the queryset
flow = server.flows.filter(owner_name="admin")[0]
# Get the last item in the queryset
flow = server.flows.filter(owner_name="admin")[-1]
# Get the most recent 10 runs from a flow
runs = server.flow_runs.filter(flow_id=flow.id, page_size=10).order_by("-created_at")[:10]
Supported endpoints
The following endpoints support the Django style filters and sorts:
# Return queryset with no filters
workbooks = server.workbooks.all()
# filters can be appended in new lines
workbooks = workbooks.filter(project_name=project_name)
# multiple filters can be added in a single line
workbooks = workbooks.filter(project_name=project_name, owner_name=owner_name, size__gte=1000)
# Multiple filters can be added through chaining.
workbooks = workbooks.filter(project_name=project_name).filter(owner_name=owner_name).filter(size__gte=1000)
# Find all views in a project, with a specific tag
views = server.views.filter(project_name=project_name, tags="stale")
# sort can take multiple args, with desc direction added as a (-) prefix
workbooks = workbooks.order_by("project_name", "-created_at")
# query is executed at time of iteration
for workbook in workbooks:
print(workbook)
# pagination item is still accessible
print(workbooks.total_available, workbooks.page_size, workbooks.page_number)
# methods can be chained
all_workbooks = server.workbooks.filter(project_name=project_name).order_by("-project_name")
# operators are implemented using dunderscore
all_workbooks = server.workbooks.filter(project_name__in=["Project A", "Project B"])
# How many items are in the queryset?
flows = server.flows.filter(owner_name="admin")
print(len(flows))
