【问题描述】：
好的，这是我第一次使用表单集。我正在尝试创建一个表，我可以动态添加行并填写每一行，然后提交并让 Django 将它们全部放入数据库中。每次我提交它只添加第一个表单。
文件views.py：
@main_context_wrapper
def bacteriaForm2(request,context):
if not request.user.is_authenticated():
#If user isn't authenticated, then just redirect to login
return HttpResponseRedirect('/login/')
BacteriaFormSet = formset_factory(BacteriaForm)
if request.POST:
bacteriaformset = BacteriaFormSet(request.POST, request.FILES)
if bacteriaformset.is_valid():
context["error"] = ""
for form in bacteriaformset:
form.save()
return HttpResponseRedirect('/')
else:
context["error"] = "validation"
context["bacteriaformset"] = BacteriaFormSet
context.update(csrf(request))
return render_to_response('bacteriaForm.html', context)
else:
#The request was a GET, add the form to the context
context["bacteriaformset"] = BacteriaFormSet()
#Add all siteInfo objects to allow for dynamic site info drop down menus
siteInfo = SiteInfo.objects.all()
context["siteInfo"] = siteInfo
return render(request, "bacteriaForm.html", context)
模板：
{% extends "inherited/main.html" %}
{% block content %}
<h1> Bacteria Entry Form </h1>
<form action='/bacteriaForm/' method="post">{% csrf_token %}
{{bacteriaformset.management_form}}
{% if error == "validation" %}
<div class="alert alert-danger">
<p>
<strong>Error: </strong>Form not completed properly.
</p>
</div>
{% endif %}
<table id="id_forms_table">
<tr>
{% for field in bacteriaformset.forms.0 %}
{% if not field.is_hidden %}
<th>{{ field.label }}</th>
{% endif %}
{% endfor %}
</tr>
{% for f in bacteriaformset.management_form %}
{{ f }}
{% endfor %}
{% for f in bacteriaformset.forms %}
<tr id="{{ f.prefix }}-row" class="dynamic-form">
{% for field in f %}
{% if not field.is_hidden %}
<td>
{{ field.errors }}
{{ field }}
</td>
{% else %}
<td valign="bottom">{{ field }}</
{% endif %}
{% endfor %}
<td{% if forloop.first %} class="hidden"{% endif %}>
<a id="remove-{{ form.prefix }}-row" href="javascript:void(0)" class="delete-row">delete</a>
</td>
</tr>
{% endfor %}
<tr>
<td colspan="4"><a href="javascript:void(0)" class="add-row">add property</a></td>
</tr>
</table>
<div>
<input type="submit" value="submit" />
</div>
</form>
<script>
$(function () {
$('.add-row').click(function() {
return addForm(this, 'form');
});
$('.delete-row').click(function() {
return deleteForm(this, 'form');
});
});
function updateElementIndex(el, prefix, ndx) {
var id_regex = new RegExp('(' + prefix + '-\\d+)');
var replacement = prefix + '-' + ndx;
if ($(el).attr("for")) $(el).attr("for", $(el).attr("for").replace(id_regex, replacement));
if (el.id) el.id = el.id.replace(id_regex, replacement);
if (el.name) el.name = el.name.replace(id_regex, replacement);
}
function addForm(btn, prefix) {
var formCount = parseInt($('#id_' + prefix + '-TOTAL_FORMS').val());
var row = $('.dynamic-form:first').clone(true).get(0);
$(row).removeAttr('id').insertAfter($('.dynamic- form:last')).children('.hidden').removeClass('hidden');
$(row).children().not(':last').children().each(function() {
updateElementIndex(this, prefix, formCount);
$(this).val('');
});
$(row).find('.delete-row').click(function() {
deleteForm(this, prefix);
});
$('#id_' + prefix + '-TOTAL_FORMS').val(formCount + 1);
return false;
}
function deleteForm(btn, prefix) {
$(btn).parents('.dynamic-form').remove();
var forms = $('.dynamic-form');
$('#id_' + prefix + '-TOTAL_FORMS').val(forms.length);
for (var i=0, formCount=forms.length; i<formCount; i++) {
$(forms.get(i)).children().not(':last').children().each(function() {
updateElementIndex(this, prefix, i);
});
}
return false;
}
$("#id_date").datepicker();
</script>
{% endblock %}
文件 Models.py
class BacteriaEntry(models.Model):
"""

bacteria levels at a specific time. BacteriaEntry utilizes the
Djano model.
"""
siteNumber = models.IntegerField()
date = models.DateField()
sampleNumber = models.IntegerField(primary_key=True)
ecoliRawCount = models.IntegerField(null=True)
ecoli = models.DecimalField(decimal_places=10, max_digits=20, null=True)
ecoliException = models.IntegerField(null=True)

这是一些帖子数据
<QueryDict: {u'form-0-date': [u'02/24/2014'], u'form-0-comments': [u'65'], u'form- MAX_NUM_FORMS': [u'1000', u'1000'], u'form-0-coliformRawCount': [u'5'],

u'form-0-ecoli': [u'51'], u'form-0-siteNumber': [u'100']}>
我不确定我的问题出在哪里。我花了很多时间试图弄清楚这一点。我不确定出了什么问题。
