A PloneFormGen adapter that will save the data from a form to an actual content type. This way you can still use permissions, workflows, etc on the form data.
This product provides a dynamic content type to store PloneFormGen form data into. It leverages schemaextenders ability to dynamically add extra fields on a content type so that you essentially get a persistent copy of your form.
The product adds a “Save Data to Content Adapter” item to the “Add new..” drop down for the PloneFormGen Form. Once enabled, when a user submits a form, a new content item is created with that data and located in the adapter.
Upon save data adapter creation, user can choose to use any content type that has ‘uwosh.pfg.d2c’ configured as the ‘product’ in the FTI, to store the form submission.
So besides the original FormSaveData2ContentEntry, its clone types can also be used to store form data - whether added to types tool via code, genericsetup profile or by manually copying the FormSaveData2ContentEntry FTI in portal_types tool (and then renaming it appropriately).
The type names can be translated simply by adding them to plone.po in the language-specific locale/LC_MESSAGES subdirectory.
Upgrading to 2.0
You must run the upgrade step in the add/remove product control panel in order for you to successfully upgrade to 2.0 otherwise, your data adapter will not display it’s contents properly.
Don’t forget to enable the adapter after it is added to the form!
It is often very useful to assign a placeful workflow onto a save data content type. Normally, this is rather cumbersome to do; however, d2c now provides a nice widget to make this sort of action automatic(automatically create missing workflow policy).
Compatible with versions of PloneFormGen >= 1.2.2 and Plone 3.x -> 4.x.
Version 1.0 derives the new D2C saved data adapter from the BTree folder class. This allows Plone 3.x sites to handle larger numbers of content items inside the D2C objects. There is an upgrade step that allows pre-1.0 D2C objects to get migrated to BTree storage. Version 1.0 also works with Plone 4. However, if you have a Plone 3.x site that uses pre-1.0 D2C and you upgrade to Plone 4 and only then upgrade to 1.0+ D2C, the upgrade step that migrates D2C storage to BTree storage may not work. We recommend that you first upgrade to 1.0+ D2C then upgrade to Plone 4.
D2C Form Images
Since D2C 2.1, there has been the ability for PFG file fields to behave like plone image fields with scales. Just select the ‘Is Image’ checkbox in the PFG file field settings.
To access scales for an image, you must construct a url like:
or for original
Upgrade old should-be d2c images
First, make sure you select that the field is an image in the corresponding ploneformgen form.
Then, go to the zmi, portal_setup, upgrades tab, select uwosh.pfg.d2c:default, click to show old and select the image-scales upgrade to run.
In order for this to work, you’ll need to disable the schemaextender cache:
archetypes.schemaextender\archetypes\schemaextender\extender.py line 113 disable CACHE_ENABLED
Finding created d2c object on request
Sometimes you need to know what object you just created was to redirect or perhaps do extra processing. D2C sets values on the request environ so you can get that information:
Content object methods
- getValue(fieldid, default=None)
- get the value of a field
- setValue(fieldid, value)
- set the value for a field
- get connected pfg form
- get connected pfg content adapter
