Fields, Widgets and Constraints for Grok

Project Description

megrok.form is a helper package that provides some useful fields, widgets and constraints for Grok.

Fields

  • Email, a TextLine field with a default contraint
  • HTML, a Text field that uses z3c.widget.tiny
  • File, from collective.namedfile
  • Image, from collective.namedfile
  • BlobFile, from collective.namedblobfile
  • BlobImage, from collective.namedblobfile

Widgets

megrok.form overrides the default widgets for:

  • zope.interface.schema.Date (using zc.datetimewidget.widget.DateWidget)
  • zope.interface.schema.Datetime (using zc.datetimewidget.widget.DatetimeWidget)

And add new widgets for Image and File (from collective.namedfile).

Validators / Constraints

megrok.form add constraints for:

  • SSN
  • US Phone Numbers
  • International Phone Numbers
  • Zip Code
  • URL
  • Email

Installation

To use megrok.form under Grok all you need is to install megrok.form as an egg and include it’s zcml. The best place to do this is to make megrok.form a dependency of your application by adding it to your install_requires list in setup.cfg. If you used grokprojet to create your application setup.cfg is located in the project root. It should look something like this:

install_requires=['setuptools',
                  'grok',
                  'megrok.form',
                  # Add extra requirements here
                  ],

Then include megrok.form in your configure.zcml. If you used grokproject to create your application it’s at src/<projectname>/configure.zcml. Add the include line after the include line for grok, but before the grokking of the current package. It should look something like this:

<include package="grok" />
<include package="megrok.form" />
<grok:grok package="." />

Then run bin/buildout again. You should now see buildout saying something like:

Getting distribution for 'megrok.form'.
Got megrok.form 0.2.2.

That’s all.

Using Blob Storage

To use blob storage you need to change zodb definition in your parts/zopectl/zope.conf like this:

<zodb>
  <blobstorage>
    <filestorage>
      path /path_to_your_app/parts/data/Data.fs
    </filestorage>
    blob-dir /path_to_your_app/parts/data/blobs
  </blobstorage>
</zodb>

The blob-dir specifies where you want to store blobs.
