Django没有为表示booleanfield的html选择列表生成“selected ='selected'”

请原谅长代码,但问题本身很短。

在MySQL 2.5上使用带有MySQL服务器版本的Django 1.2.1:5.1.37和mysqldb 1.2.2

对于模型

QUALIFICATION_TYPE_CHOICES = ((1, 'WGH'), (2, 'PQR'))
class Qualification(models.Model):
    name = models.CharField(max_length=50)
    qualification_type = models.PositiveSmallIntegerField(choices=QUALIFICATION_TYPE_CHOICES)
    is_active = models.BooleanField("Item status",db_index=True,help_text="Only active items are visible on rest of this website")
    def __unicode__(self):
        return u'%s' % (self.name)
    class Meta:
        ordering = ['qualification_type', 'name']
        unique_together = (("qualification_type", "name"),)

使用自定义模型

STATUS_CHOICES = ((0, 'Inactive'), (1, 'Active'))
class EditQualificationForm(forms.ModelForm):
    name = forms.CharField(label='* Unique Name', max_length=50,help_text="(Required, max 50 characters)",widget=forms.TextInput(attrs={'class':'textInput',}))
    qualification_type = forms.TypedChoiceField(label='Type',coerce=int,empty_value=None,choices=QUALIFICATION_TYPE_CHOICES,widget=forms.Select(attrs={'class':'selectInput',}))
    is_active = forms.TypedChoiceField(label='* Is this Qualification active?',help_text="xyz",coerce=int,empty_value=0, choices=STATUS_CHOICES,widget=forms.Select(attrs={'class':'selectInput',}))
    class Meta:
        model = Qualification

模板代码

{% if form.non_field_errors %}
    <div class="error">
    {% for error in form.non_field_errors %}
        <p class="errorField"><strong>{{ error }}</strong></p>
    {% endfor %}
    </div>
{% endif %}

{% for field in form.visible_fields %}
    {% if field.errors %}
        <div class="ctrlHolder error">
        {% for error in field.errors %}
            <p class="errorField"><strong>{{ error }}</strong></p>
        {% endfor %}
    {% else %}
        <div class="ctrlHolder">
    {% endif %}
        {{ field.label_tag }}
        {{ field }}
        <p class="formHint">{{ field.help_text }}</p>
        </div>
{% endfor %}

{% for hidden in form.hidden_fields %}
    {{ hidden }}
{% endfor %}

正在生成以下输出

<div class="ctrlHolder">
    <label for="id_qualification_type">Type</label>
    <select id="id_qualification_type" class="selectInput" name="qualification_type">
        <option value="1" selected="selected">WGH</option>
        <option value="2">PQR</option>
    </select>
    <p class="formHint"></p>
</div>

<div class="ctrlHolder">
    <label for="id_is_active">* Is this Qualification active?</label>
    <select id="id_is_active" class="selectInput" name="is_active">
        <option value="0">Inactive</option>
        <option value="1">Active</option>
    </select>
    <p class="formHint">xyz</p>
</div>

所以qualified_type的html选择列表正在获得正确的<option value="1" selected="selected">WGH</option>,但is_active的正确选项未被选中(生成的html中没有selected="selected" for_active)。

这曾经比较早。我已经将布尔选择映射到0和1,它与mysql和python非常吻合。我在某种程度上错过了注意到什么时候停止生成正确的html。但我很肯定它在Django-1.2.1之前工作。

我猜这与empty_value表单字段中不必要的is_active有关。

好的,我找到了。我已经阅读了几次发行说明,所以我真的不知道我是如何错过它的。
