Project Description

megrok.z3cform.layout provides generic templates that can be used out-of-the-box with megrok.z3cform.base. These templates are totally independent from the megrok.z3cform.base library, meaning you can simply swap or override them.

Getting started

We import the base components to test our form layout:

>>> from megrok.z3cform.base import DisplayForm, EditForm, Fields
>>> from grokcore.component import context, implements
>>> from grokcore.component.testing import grok, grok_component

Let’s start with a simple example. We create a person object:

>>> from zope.interface import Interface, implements
>>> from zope.schema import TextLine

The Interface of our Object:

>>> class IPerson(Interface):
...   name = TextLine(title = u'Name')
...   age = TextLine(title = u'Age')

The class of our Object:

>>> class Person(object):
...   implements(IPerson)
...   name = u""
...   age = u""

And our instance:

>>> peter = Person()
>>> peter
<megrok.z3cform.base.ftests.Person object at ...>
>>> IPerson.providedBy(peter)
True

Rendering forms

For now, megrok.z3cform.layout provides only one template that works for all the different kinds of forms:

>>> class Edit(EditForm):
...   context(Interface)
...   fields = Fields(IPerson)

>>> grok_component('edit', Edit)
True

>>> from zope.component import getMultiAdapter
>>> from zope.publisher.browser import TestRequest
>>> request = TestRequest()

>>> edit = getMultiAdapter((peter, request), name="edit")
>>> print edit()
<form action="http://127.0.0.1" method="post"
      enctype="multipart/form-data" class="form-edit">
  <div class="errors">
  </div>
  <p class="documentDescription"></p>
  <input type="hidden" name="camefrom" />
    <div id="edition-fields">
    <div class="field ">
      <label for="form-widgets-name">
        <span>Name</span>
        <span class="fieldRequired" title="Required">
          <span class="textual-info">(Required)</span>
        </span>
      </label>
      <div class="widget">
    <input id="form-widgets-name" name="form.widgets.name"
           class="text-widget required textline-field"
           value="" type="text" />
</div>
    </div>
    <div class="field ">
      <label for="form-widgets-age">
        <span>Age</span>
        <span class="fieldRequired" title="Required">
          <span class="textual-info">(Required)</span>
        </span>
      </label>
      <div class="widget">
    <input id="form-widgets-age" name="form.widgets.age"
           class="text-widget required textline-field"
           value="" type="text" />
</div>
    </div>
    </div>
    <div id="actionsView">
      <span class="actionButtons">
<input id="form-buttons-apply" name="form.buttons.apply"
       class="submit-widget button-field" value="Apply"
       type="submit" />
      </span>
    </div>
</form>

It works the same for a form with no actions:

>>> class Display(DisplayForm):
...   context(Interface)
...   fields = Fields(IPerson)

>>> grok_component('display', Display)
True

>>> view = getMultiAdapter((peter, request), name="display")
>>> print view()
<form action="http://127.0.0.1" method="post"
      enctype="multipart/form-data" class="form-display">
   <div class="errors">
   </div>
   <p class="documentDescription"></p>
   <input type="hidden" name="camefrom" />
     <div id="edition-fields">
       <div class="field ">
         <label for="form-widgets-name">
           <span>Name</span>
           <span class="fieldRequired" title="Required">
             <span class="textual-info">(Required)</span>
           </span>
         </label>
         <div class="widget">
           <span id="form-widgets-name"
                 class="text-widget required textline-field"></span>
         </div>
      </div>
      <div class="field ">
        <label for="form-widgets-age">
          <span>Age</span>
          <span class="fieldRequired" title="Required">
            <span class="textual-info">(Required)</span>
          </span>
        </label>
        <div class="widget">
          <span id="form-widgets-age"
                class="text-widget required textline-field"></span>
        </div>
      </div>
    </div>
 </form>
