Example

Here’s a complete example of how to use the redcaplite package:

import redcaplite

# Create an instance of RedcapClient
r = redcaplite.RedcapClient('https://redcap.vumc.org/api/', 'your_token')

# Get arms
arms = r.get_arms()
print("Arms:", arms)

# Delete specific arms
r.delete_arms(arms=[3])
print("Arm 3 deleted successfully.")

Improved CSV Export with pd_read_csv_kwargs

We've added a new feature to our export_records and get_report methods to give you more control over the CSV export process. With the pd_read_csv_kwargs parameter, you can now specify additional keyword arguments to pass to pandas.read_csv, allowing you to customize the data types of your exported data.

Handling Data Types with dtype

One common use case for pd_read_csv_kwargs is to specify the data type of specific columns in your exported data. For example, you may want to ensure that a column like participant_study_id is exported as a string, rather than being automatically converted to a numeric type. Here's an example of how you can use pd_read_csv_kwargs to achieve this:

export_records(pd_read_csv_kwargs={'dtype':{'participant_study_id': str}})

In this example, we're passing a dictionary to pd_read_csv_kwargs with a single key-value pair: dtype. The value of dtype is another dictionary that specifies the data type for the participant_study_id column. By setting this to str, we ensure that the values in this column are exported as strings, rather than being converted to a numeric type.

Benefits of using pd_read_csv_kwargs

By using pd_read_csv_kwargs to customize the CSV export process, you can:

• Ensure that sensitive data, like participant IDs, are exported in a format that preserves their original data type
• Avoid issues with automatic data type conversion, which can lead to errors or unexpected behavior downstream
• Take advantage of pandas' robust data type handling capabilities to fine-tune your exported data

We hope this new feature helps you to work more efficiently and effectively with your REDCap data!
