如何在django formset中显示隐藏的autofield [英] How to show hidden autofield in django formset

问题描述

默认情况下，隐藏使用表单集显示的Django自动域。什么是最好的方式显示？

A Django autofield when displayed using a formset is hidden by default. What would be the best way to show it?

目前，该模型被声明为，

At the moment, the model is declared as,

class MyModel:
   locid = models.AutoField(primary_key=True)
   ...

当使用Django表单呈现时，

When this is rendered using Django formsets,

class MyModelForm(ModelForm):
  class Meta:
    model = MyModel
    fields = ('locid', 'name')

它显示在页面上，

<input id="id_form-0-locid" type="hidden" value="707" name="form-0-locid"/>

感谢。

编辑

我创建了这样的表单 -

I create the formset like this -

LocFormSet = modelformset_factory(MyModel) 
pformset = LocFormSet(request.POST, request.FILES, queryset=MyModel.objects.order_by('name')) 

---

第二次修改

看起来我没有使用我在那里定义的自定义表单类，所以问题需要稍微修改。

Looks like I'm not using the custom form class I defined there, so the question needs slight modification..

如何从自定义表单（将显示隐藏字段）以及使用自定义查询器创建表单？

此刻，我可以从BaseModelFormSet类继承，并使用自定义查询集，也可以使用ModelForm类将自定义字段添加到表单。有没有办法做一个表单？

At the moment, I can either inherit from a BaseModelFormSet class and use a custom query set, or I can use the ModelForm class to add a custom field to a form. Is there a way to do both with a formset?

第三次修改

我正在使用

class MyModelForm(ModelForm):
  def __init__(self, *args, **kwargs):
    super(MyModelForm, self).__init__(*args, **kwargs)
    locid = forms.IntegerField(min_value = 1, required=True)
    self.fields['locid'].widget.attrs["type"] = 'visible'
    self.queryset = MyModel.objects.order_by('name')
  class Meta:
    model = MyModel
    fields = ('locid', 'name')

LocFormSet = modelformset_factory(MyModel, form = MyModelForm)
pformset = LocFormSet()

但这仍然不是

• 显示locid


• 使用指定的自定义查询。

推荐答案

好的，上面的方法都没有为我工作。我从模板方面解决了这个问题，最后。

Okay, none of the approaches above worked for me. I solved this issue from the template side, finally.

• 有一张机票（ http://code.djangoproject.com/ticket/10427 ），它为模板变量添加了一个值选项形成。例如，它允许

• There is a ticket filed (http://code.djangoproject.com/ticket/10427), which adds a "value" option to a template variable for a form. For instance, it allows,

{{form.locid.value}}

{{form.locid.value}}

被显示。这可以作为补丁来使用，可以使用patch -p0 file.patch安装在SVN版本的django中。

to be shown. This is available as a patch, which can be installed in the SVN version of django using "patch -p0 file.patch"

• 请记住，{{form.locid.value}}变量将使用结合与不可见表单 - 否则，表单集的提交和保存操作将崩溃。

• Remember, the {{form.locid.value}} variable will be used in conjunction with the invisible form - otherwise, the submit and save operations for the formset will crash.

这是与{{form.locid.data}}相同的不，如上述票证中所述。

This is Not the same as {{form.locid.data}} - as is explained in the ticket referred to above.
