为什么我的排除字段仍然以这种Django形式出现? [英] Why does my excluded field still appear in this Django form?

问题描述

我在表单的Meta类中使用 exclude 从表单中排除要以编程方式填写的字段，但该字段仍显示在表单中.

I'm using exclude in my form's Meta class to exclude a field from my form that I want to fill in programatically, but it's still showing up in the form.

以下是代码摘录:

# Model
class Info(models.Model):
    completed_by = models.ForeignKey(User, related_name='+')

# Form
class InfoForm(forms.ModelForm):
    class Meta:
        model = Info
        exclude = ('created_by',)  #ETA: added comma to make this a tuple
        widgets = {
            'some_other_field': forms.HiddenInput(),
            'some_other_field2': forms.DateInput(attrs={'readonly': True}),
        }

# View
form = InfoForm(initial={'some_other_field': value}, 
                          prefix='info', instance=info)
return direct_to_template(request, 'myapp/info.html', locals())

# Template
<form class='uniForm' method='POST'>
{% csrf_token %}
<fieldset class='inlineLabels'>{{ form|as_uni_form }}</fieldset>
<input type='submit' name='action' value='Save' />
</form>

这似乎应该非常简单，而且我知道我之前已经成功完成了.为了确保这不是一个因素，我已经删除/重新创建了数据库并清除了浏览器缓存.我还尝试将其设置为 HiddenInput 字段，就像 some_other_field (也是 ForeignKey 字段)一样，但它仍显示在表单上

This seems like it should be pretty simple, and I know I've done it successfully before. I've deleted/recreated my DB and cleared my browser cache, just to be sure that's not a factor. I also tried making it a HiddenInput field, just like some_other_field (which is a ForeignKey field also), but it still shows up on the form.

这里缺少什么吗?uni_form是否以某种方式覆盖设置?如果没有，关于我可能在调试中寻找什么的任何建议，以查看发生的原因/原因?

Is there something here I'm missing? Is uni_form overriding the setting somehow? If not, any advice as to what I might look for in debug to see where/why this is happening?

(使用Django版本1.2.7)

推荐答案

排除需要一个元组，所以您需要

exclude needs a tuple, so you need

# note the extra comma
exclude = ('created_by',)

django遍历 exclude ，并且由于字符串是可迭代的(返回每个字符)，因此不会引发错误

django iterates through the exclude, and since strings are iterable (return each character) this doesn't throw an error
