Python wtforms中的字段字典

我想知道是否可以使用wtforms在表单中创建字段字典

原因是我有一个位置字典，我使用jinja将其呈现到一个表中。在使用wtforms之前，我可以轻松处理以下各项的输入：

{% for locKey, loc in locDict.iteritems() %}
<tr>
    <td>{{ loc['name'] }}</td>
    <td><input type="text" id="{{ locKey }}" name="locKey"></td>
</tr>
{% endfor %

采用2的方法，然后创建一个难看的手动脚本来创建html模板（即，使html模板显式地具有

{form.loclocOne}}

等。这是相当难看的，但迄今为止我能看到的唯一可行的解决方案

注意：正如您在上面的示例中所看到的，我需要在每个字段中看到不同的最大值

from wtforms.validators import NumberRange
from wtforms import Form, IntegerField

# dictionary of locations with certain attributes
locDict = {}
locDict['locOne'] = {'name': 'Location One', 'popn': 1000}
locDict['locTwo'] = {'name': 'Location Two', 'popn': 2000}
locDict['locThree'] = {'name': 'Location Three', 'popn': 3000}

class testForm(Form):
    # standard field
    normalField = IntegerField('Normal Field', validators=[NumberRange(min=0, max=100)])

    # initiate dictionary of fields
    locFields = {}
    for locKey, loc in locDict.iteritems():
        locFields[locKey] = IntegerField(loc['name'], validators=[NumberRange(min=0, max=loc['popn'])])

# test the form
testFormInstance = testForm()
print testFormInstance.normalField
print testFormInstance.locFields['locOne']
print testFormInstance.locFields['locTwo']
print testFormInstance.locFields['locThree']

# returns:
#<input id="normalField" name="normalField" type="text" value="">
#<UnboundField(IntegerField, ('Location One',), {'validators': [<wtforms.validators.NumberRange object at 0x7f8367970050>]})>
#<UnboundField(IntegerField, ('Location Two',), {'validators': [<wtforms.validators.NumberRange object at 0x7f8367963f90>]})>
#<UnboundField(IntegerField, ('Location Three',), {'validators': [<wtforms.validators.NumberRange object at 0x7f83679700d0>]})>

{% for locKey, loc in locDict.iteritems() %}
<tr>
    <td>{{ loc['name'] }}</td>
    <td>{{ form.loc{{ locKey }} }}</td>
</tr>
{% endfor %}
