Ticket #13023: 13023_full_max_num_patch.diff

File 13023_full_max_num_patch.diff, 35.4 KB (added by Gabriel Hurley, 15 years ago)

Updated: Noticed another place in inlines.js that needed correction. Complete patch to make max_num default to None instead of 0, including tests and docs.

    653653Limiting the number of editable objects

     657
    656658As with regular formsets, you can use the ``max_num`` parameter to
    657 ``modelformset_factory`` to limit the number of forms displayed. With
    658 model formsets, this property limits the query to select only the maximum
    659 number of objects needed::
     659``modelformset_factory`` to limit the number of extra forms displayed.
    660660
     661``max_num`` does not prevent existing objects from being displayed::
     662
    661663    >>> Author.objects.order_by('name')
    662664    [<Author: Charles Baudelaire>, <Author: Paul Verlaine>, <Author: Walt Whitman>]
    663665
    664     >>> AuthorFormSet = modelformset_factory(Author, max_num=2, extra=1)
     666    >>> AuthorFormSet = modelformset_factory(Author, max_num=1)
    665667    >>> formset = AuthorFormSet(queryset=Author.objects.order_by('name'))
    666     >>> formset.initial
    667     [{'id': 1, 'name': u'Charles Baudelaire'}, {'id': 3, 'name': u'Paul Verlaine'}]
     668    >>> [x.name for x in formset.get_queryset()]
     669    [u'Charles Baudelaire', u'Paul Verlaine', u'Walt Whitman']
    668670
    669 If the value of ``max_num`` is higher than the number of objects returned, up to
    670 ``extra`` additional blank forms will be added to the formset, so long as the
    671 total number of forms does not exceed ``max_num``::
     671If the value of ``max_num`` is geater than the number of existing related
     672objects, up to ``extra`` additional blank forms will be added to the formset,
     673so long as the total number of forms does not exceed ``max_num``::
    672674
    673675    >>> AuthorFormSet = modelformset_factory(Author, max_num=4, extra=2)
    674676    >>> formset = AuthorFormSet(queryset=Author.objects.order_by('name'))
    … …  
    679681    <tr><th><label for="id_form-2-name">Name:</label></th><td><input id="id_form-2-name" type="text" name="form-2-name" value="Walt Whitman" maxlength="100" /><input type="hidden" name="form-2-id" value="2" id="id_form-2-id" /></td></tr>
    680682    <tr><th><label for="id_form-3-name">Name:</label></th><td><input id="id_form-3-name" type="text" name="form-3-name" maxlength="100" /><input type="hidden" name="form-3-id" id="id_form-3-id" /></td></tr>
    681683
     684.. versionchanged:: 1.2
     685
     686A ``max_num`` value of ``None`` (the default) puts no limit on the number of
     687forms displayed.
