I am no longer actively developing this code base. Please continue to submit bugs and I'll do my best to tackle them.
PyCap is a python module exposing the REDCap API through some helpful abstractions. Information about the REDCap project can be found at http://project-redcap.org/.
Available under the MIT license.
Canonical documentation can be found on ReadTheDocs.
Currently, these API calls are available:
- Export Records
- Export Metadata
- Delete Records
- Import Records
- Export File
- Import File
- Delete File
- Export Users
- Export Form Event Mappings
Events and Arms are automatically exported for longitudinal projects (see below).
requests (>= 1.0.0)
$ pip install requests
>>> import redcap
# Init the project with the api url and your specific api key
>>> project = redcap.Project(api_url, api_key)
# Export all data
>>> all_data = project.export_records()
# import data
>>> data = [{'subjid': i, 'age':a} for i, a in zip(range(1,6), range(7, 13))]
>>> num_processed = project.import_records(data)
# For longitudinal projects, project already contains events, arm numbers
# and arm names
>>> print project.events
...
>>> print project.arm_nums
...
>>> print project.arm_names
...
# Import files
>>> fname = 'your_file_to_upload.txt'
>>> with open(fname, 'r') as fobj:
... project.import_file('1', 'file_field', fname, fobj)
# Export files
>>> file_contents, headers = project.export_file('1', 'file_field')
>>> with open('other_file.txt', 'w') as f:
... f.write(file_contents)
# Delete files
>>> try:
... project.delete_file('1', 'file_field')
... except redcap.RedcapError:
... # This throws if an error occured on the server
... except ValueError:
... # This throws if you made a bad request, e.g. tried to delete a field
... # that isn't a file
# Delete record
>>> response = project.delete_record('1')
# Export form event mappings
>>> fem = project.export_fem()
...
