Database import / export Rake tasks
This Rake extension provides many ways to import / export data to / from database. At this time, the available tasks only deal with CSV format.
Available tasks are :
- db:import:csv - Import data from a CSV file right into the table associated to a given model
- db:export:csv - Export data from the given model table into a CSV file
- db:export:csv:all - It checks for presence, length, format and uniqueness. There is no guarantee that a validated email is real and deliverable.
In your Rails app root, use the following command-line:
cd lib/tasks git clone git://github.com/synbioz/database.rake.git database
Import data from a CSV file into given model table:
# Your CSV file has headers rake db:import:csv MODEL=my_model_to_fill CSV=path_to_csv_file.csv # You want to purge the table before importing data rake db:import:csv MODEL=my_model_to_fill CSV=path_to_csv_file.csv PURGE=boolean # Your CSV file has no headers, fieldnames can be deduce, you have to specify it rake db:import:csv MODEL=my_model_to_fill CSV=path_to_csv_file.csv FIELDS=field1_name,field2_name,...
Export given model data into CSV file:
# Data will be written to a file having the same name as the given model rake db:export:csv MODEL=model_name # Data will be written to the specified file rake db:export:csv MODEL=model_name CSV=path_for_the_generated_csv_file.csv
Export all models data into many CSV files:
