A PloneFormGen Action Adapter for SQL storage

Project description


The goal for this package is:

  • to make SQL storage from PloneFormGen easy

  • to be usable with collective.megaphone

To achieve this, we create a new PloneFormGen action-adapter. This uses SQLAlchemy (collective.lead) to save the form data to the database. (SQLAlchemy should work on most SQL dialects.)

You could also save PFG data in SQL by using a Z SQL Method as an after-validation script, as described in the SQL-CRUD-tutorial. This works, but:



To install a complete development setup:

svn co sqlpfg-plone4
cd sqlpfg-plone4
./bin/buildout -c buildout-dvl.cfg

Or, for Plone 3:

svn co sqlpfg-plone3
cd sqlpfg-plone3
./bin/buildout -c buildout-dvl.cfg

If you use another buildout configuration, be sure to include the “Known good set” for for your version of Plone. In the case of Plone 3, you’ll also want to pin z3c.form to 1.9.0.


As a site admin, go to the “SQL Settings” in Plone’s control panel. You’ll be taken to “@@sqlpfg-controlpanel”. Here you can set your database connection settings.


To save a form’s data in the database, add an “SQL Storage” from the “Add new…” menu in the Form Folder. Give it a title and save it.

A database table will be created. Its name is generated (from the Form Folder’s id, among others), you can see it by viewing the adapter object. The table has an ‘id’ column, and a column for each form field.

That’s it! From now on, succesfully submitted forms will be stored in the database.

Usage with collective.megaphone

The product will work just as well with collective.megaphone. However, to be able to add the action adapter to an Action Letter or Megaphone Action, you have to add “SQLPFGAdapter” to the “Allowed content types” via the ZMI.

The product collective.megaphonesql can do this for you.


This product is under development. For now, we have major limitations:

  • Not all PloneFormGen fields work, notably:

    • file field

    • rating-scale field

  • Adding and removing fields, or changing their names, doesn’t change the database table. Field names for which there is no column will just be discarded.

Compatibility / Dependencies

Tested with:

  • Plone: 3.3.5, 4.0

  • PloneFormGen: 1.6.0b4, 1.6.0b5

  • megaphone: 1.4.1, 2.0b1

  • collective.lead 1.0, SQLAlchemy 0.4.8

  • SQL: MySQL 5.1.41

This product uses for its controlpanel. In order for it to work, use its “Known good set” (see section “Developers” above).
