Project Description

dolmen.widget.file is a package that walks hand-in-hand with dolmen.file. It provides a useable and pluggable way to render the dolmen.file.FileField in a z3c.form.Form, using Grok (through megrok.z3cform.base)

Example

We are going to develop here a small example, to demonstrate the use of dolmen.widget.file. First, we need to create a model content with a file field:

>>> import dolmen.file
>>> import grokcore.component as grok
>>> from zope.interface import Interface
>>> from zope.schema.fieldproperty import FieldProperty


>>> class ITravelMount(Interface):
...   luggage = dolmen.file.FileField(title=u'Luggages')


>>> class Mammoth(grok.Context):
...   grok.implements(ITravelMount)
...   luggage = FieldProperty(ITravelMount['luggage'])

We now have a travel mammoth on which we can add a luggage. Now, we need a form to edit the animal:

>>> from megrok.z3cform.base import EditForm
>>> class EditMammoth(EditForm):
...    grok.name('edit')
...    grok.context(ITravelMount)

>>> grok.testing.grok_component('edit', EditMammoth)
True

Let’s instanciate a Mammoth and try to call the form on it:

>>> from zope.component import getMultiAdapter
>>> from zope.publisher.browser import TestRequest

>>> manfred = Mammoth()
>>> request = TestRequest()

>>> form = getMultiAdapter((manfred, request), name='edit')
>>> form.updateWidgets()
>>> print form.widgets['luggage'].render()
<span id="form-widgets-luggage"
      class="file-widget required filefield-field">
<BLANKLINE>
<BLANKLINE>
<BLANKLINE>
    <input type="file" id="form-widgets-luggage-input"
           name="form.widgets.luggage" />
<BLANKLINE>
<BLANKLINE>
</span>
<BLANKLINE>

Now, let’s try with a value:

>>> manfred.luggage = "A nice data"
>>> form = getMultiAdapter((manfred, request), name='edit')
>>> form.updateWidgets()
>>> print form.widgets['luggage'].render()
<span id="form-widgets-luggage"
    class="file-widget required filefield-field">
<BLANKLINE>
  <div style="padding-top: 1em;">
  <input type="radio" value="nochange" checked="checked"
       class="noborder"
       name="form.widgets.luggage.nochange"
           onclick="document.getElementById('form-widgets-luggage-input').disabled=true"
           id="form-widgets-luggage-nochange" />
  <label for="form-widgets-luggage-nochange">Keep existing file</label>
    <br />
<BLANKLINE>
    <label for="form-widgets-luggage-delete">Delete existing file</label>
  <br />
  <input type="radio" value="" class="noborder"
         name="form.widgets.luggage.nochange"
         onclick="document.getElementById('form-widgets-luggage-input').disabled=false"
         id="form-widgets-luggage-replace" />
      <label for="form-widgets-luggage-replace">Replace with new file</label>
</div>
  <div style="padding-left: 1.5em; padding-top: 0.5em;">
  <input type="file" id="form-widgets-luggage-input"
           name="form.widgets.luggage" />
  <script type="text/javascript">document.getElementById('form-widgets-luggage-input').disabled=true;</script>
  </div>
</span>
<BLANKLINE>
