Question

我有动态表格：

class CollectionRequestParamForm(Form):
    param_human_name = StringField(validators=[DataRequired()])
    param_request_name = StringField()


class CollectionRequestParamCombinedForm(FlaskForm):
    params = FieldList(FormField(CollectionRequestParamForm), min_entries=1)
    submit = SubmitField('Submit')

用户发送表单后，我在我的收藏中添加这样的dict（我使用MongoDB）：

example_form = {
    'Имя': 'name',
    'Возраст': 'age'
}

当然，如果需要我可以改变我的数据结构，例如：

example_form = [
    {'param_human_name': 'Имя', 'param_request_name': 'name'},
    {'param_human_name': 'Возраст', 'param_request_name': 'age'},
]

现在，我如何用我的dict中的数据填充表单？我累了：

collection_request_params_form = CollectionRequestParamCombinedForm()
i = 0
for key, value in example_form.items():
    collection_request_params_form.params.data[i]['param_human_name'] = key
    collection_request_params_form.params.data[i]['param_request_name'] = value
    ## Or...
    collection_request_params_form.data['params'][i]['param_human_name'] = key
    collection_request_params_form.data['params'][i]['param_request_name'] = value
    i += 1

这不起作用:(

你可以试试这个，我不确定这是否有效。

i=0
for ex in example_form:
  for key,value in ex.items():
    collection_request_params_form.params.data[i]['param_human_name'] = key
    collection_request_params_form.params.data[i]['param_request_name'] = value
     ## Or...
    collection_request_params_form.data['params'][i]['param_human_name'] = key
    collection_request_params_form.data['params'][i]['param_request_name'] = value
    i+=1

如果这不起作用，您能解释下一行的数据吗？

collection_request_params_form.params.data[i]['param_human_name'] = key
