Django formset重複值

我使用jQuery.formsets在Django模板下動態創建更多表單。問題是我得到重複值輸入到數據庫。Django formset重複值

據我可以告訴由jQuery.formsets生成的ID是正確的，因爲當我打印出request.POST在視圖下它顯示正確的值。

在考慮中的值是 '觀察員一/二/三' 與點擊之前以下ID提交：

id_form-O-observed_by_0
形式-1- id_form-0-observed_by_0
形式-2- id_form-0-observed_by_0

request.POST：

<QueryDict: {u'form-1-form-INITIAL_FORMS': [u''], u'form-1-form-MAX_NUM_FORMS': [u''], u'commune': [u'Tartu'], u'additional_workgroups_view_0': [u''], u'form-0-observed_by_1': [u'3'], u'form-0-observed_by_0': [u'Observer ONE'], u'sample': [u''], u'remarks': [u''], u'access_edit': [u'private'], u'district': [u'Tartu'], u'country_1': [u'EE'], u'access_view': [u'public'], u'form-2-form-MAX_NUM_FORMS': [u''], u'substrate_1': [u''], u'substrate_0': [u''], u'geom': [u''], u'exact_date_and_time': [u''], u'latitude': [u'25.36698180'], u'csrfmiddlewaretoken': [u'AJTXFtEYQbX0pdBdvSe53443HKHN5dvg'], u'method': [u'MAP'], u'coordinate_uncertainty_in_meters': [u'200'], u'form-1-form-TOTAL_FORMS': [u''], u'elevation': [u''], u'country_0': [u'Estonia'], u'timespan_begin': [u'25-03-2013 11:08'], u'locality_text': [u'Ravila 19'], u'additional_users_view_0': [u''], u'timespan_end': [u''], u'form-TOTAL_FORMS': [u'3'], u'form-INITIAL_FORMS': [u'0'], u'form-2-form-INITIAL_FORMS': [u''], u'taxon_node_0': [u'Fungi'], u'taxon_node_1': [u'5'], u'district_ehak': [u''], u'form-2-observed_by_1': [u'3'], u'form-2-observed_by_0': [u'Observer THREE'], u'form-1-observed_by_0': [u'Observer TWO'], u'form-1-observed_by_1': [u'1'], u'form-2-form-TOTAL_FORMS': [u''], u'commune_ehak': [u''], u'additional_users_edit_0': [u''], u'form-MAX_NUM_FORMS': [u''], u'study': [u'2'], u'longitude': [u'15.69302410'], u'additional_workgroups_edit_0': [u''], u'remarks_sample': [u''], u'kingdom_helper': [u'5']}>

但是，當我打印出formset本身時，form0和form2的值似乎是重複的。

<input type="hidden" name="form-TOTAL_FORMS" value="3" id="id_form-TOTAL_FORMS" /> 
<input type="hidden" name="form-INITIAL_FORMS" value="0" id="id_form-INITIAL_FORMS" /> 
<input type="hidden" name="form-MAX_NUM_FORMS" id="id_form-MAX_NUM_FORMS"/> 
<tr> 
    <th> 
     <label for="id_form-0-observed_by_0"></label> 
    </th> 
    <td> 
     <input style="width: 200px" name="form-0-observed_by_0" required="True" value="Observer THREE" id="id_form-0-observed_by_0" data-selectable-type="text" data-selectable-allow-new="false" data-selectable-url="/selectable/agent-personlookup/" type="text" class="span12"/> 
     <input data-selectable-type="hidden" name="form-0-observed_by_1" id="id_form-0-observed_by_1" required="True" type="hidden" style="width: 200px" value="3" class="span12" /> 
    </td> 
    </tr> 
<tr> 
    <th> 
     <label for="id_form-1-observed_by_0"></label> 
    </th> 
    <td> 
     <input style="width: 200px" name="form-1-observed_by_0" required="True" value="Observer ONE" id="id_form-1-observed_by_0" data-selectable-type="text" data-selectable-allow-new="false" data-selectable-url="/selectable/agent-personlookup/" type="text" class="span12"/> 
     <input data-selectable-type="hidden" name="form-1-observed_by_1" id="id_form-1-observed_by_1" required="True" type="hidden" style="width: 200px" value="1" class="span12"/> 
    </td> 
</tr> 
<tr> 
    <th> 
     <label for="id_form-2-observed_by_0"></label> 
    </th> 
    <td> 
     <input style="width: 200px" name="form-2-observed_by_0" required="True" value="Observer THREE" id="id_form-2-observed_by_0" data-selectable-type="text" data-selectable-allow-new="false" data-selectable-url="/selectable/agent-personlookup/" type="text" class="span12"/> 
     <input data-selectable-type="hidden" name="form-2-observed_by_1" id="id_form-2-observed_by_1" required="True" type="hidden" style="width: 200px" value="3" class="span12"/> 
    </td> 
</tr>

查看：

def observation_add(request): 
if request.method == 'POST': 
    print 'REQUEST POST START' 
    print request.POST 
    print 'REQUEST POST END' 
    ObservedByFormset = formset_factory(ObservedByForm) 
    observed_by_formset = ObservedByFormset(request.POST) 
    print 'DEBUG: FORM BEFORE VALID:', observed_by_formset

我們需要查看您的查看代碼。 – 2013-03-25 09:50:57

你去那裏：=） – ObviousCat 2013-03-25 09:55:29

但是這不會把任何東西放到數據庫中。代碼是哪裏做的？ – 2013-03-25 09:59:11

原來這是正在改變隱藏字段的值，因此搞亂了後端jquery.dj.selectable.js。該腳本必須完全放在div和for循環之間。

{% for form in formset.forms %} 
<script type="text/javascript" src="/static/selectable/js/jquery.dj.selectable.js"></script> 
<div id="table_rel">
