我正在制作一个锻炼日历网站,用户可以在其中添加不同数量的电梯,套装和代表等的锻炼。因此,我需要一个在用户点击按钮时添加字段的表单。我已经制作了一个模板和一些javascript来描述我想要实现的目标:
URL:
url(r'^add/(?P<year>[0-9]+)/(?P<month>[0-9]+)/(?P<day>[0-9]+)/$', views.add_workout, name = 'add_workout')
模板:
{% block hidden %}
{% include "workoutcal/liftrow.html" %} {# To be used by Javascript #}
{% include "workoutcal/cardiorow.html" %}
{% endblock %}
<form action="{% url 'add_workout' date.year date.month date.day %}" method="post">
<div class="row">
<div class="col-xs-2">
<p id="date">{{ date.year }}-{{ date.month }}-{{ date.day }}</p>
<input type="hidden" name="date" value="{{ date }}">
</div>
</div>
<h2 class="col-xs-12">Lifts</h2>
<div id="liftrows">
{% for i in range %}
{% include "workoutcal/liftrow.html" %}
{% endblock %}
</div>
<div class="row">
<div class="col-xs-0"></div>
<label class="col-xs-2"><button type="button" id="addliftbutton">One more lift</button></label>
</div>
<h2 class="col-xs-12">Cardio</h2>
<div id="cardiorows">
{% include "workoutcal/cardiorow.html" %}
</div>
<div class="row">
<label class="col-xs-2"><button type="button" id="addcardiobutton">One more cardio</button></label>
</div>
<div class="row">
<div class="col-xs-10"></div>
<label class="col-xs-2"><input type="submit" id="submitbutton" value="Save Workout"></label>
</div>
</form>
的javascript:
//Adding onclick to buttons
document.getElementById('addliftbutton').onclick = addLiftRow;
document.getElementById('addcardiobutton').onclick = addCardioRow;
for (var i=0; i<setsBoxes.length; i++){
setsBox = setsBoxes[i];
setsBox.onchange = insertRepFields;
}
function addLiftRow(){
var liftRowElements = document.getElementById('liftrows');
var hidden_liftrow = document.getElementById('hidden').getElementsByClassName('lift')[0];
var new_liftrow = hidden_liftrow.cloneNode(true);
liftRowElements.appendChild(new_liftrow);
}
function addCardioRow(){
var cardiorows = document.getElementById('cardiorows');
var hidden_cardiorow = document.getElementById('hidden').getElementsByClassName('cardio')[0];
var new_cardiorow = hidden_cardiorow.cloneNode(true);
cardiorows.appendChild(new_cardiorow);
}
function insertRepFields(){} // big function that inserts as many input fields as the number inside the box whose event called the function.
2个问题: 1.在Django中有更好的方法吗? 2.如果这是最好的方法,我如何将我的大型表格的数据发送回django?由于我不确切知道会有多少字段,因此我不知道如何创建一个接受不同字段和字段内字段的表单。
以下是填写表单的外观:
答案 0 :(得分:1)
实现这一目标的最佳方法是插入具有相同名称的输入,然后在Django中将所有这些输入作为列表获取:
def view(request):
inputs = request.POST.getlist('your_input_name')
for i in inputs:
Model.objects.create() # Save your model
