radio buttons display form

Question

I have in my form 3 radio buttons, when i click on each one a form appears and a parameter of my backtesting change. The problem is that when i click on save buttons nothing is saved. Before I added the check of radio buttons the save buttons was working. The click on radio buttons change the strategy of parameters. The error is with the save function when i check the radio buttons but i don't know how to resolve it.

Answer 1

Add all 3 radio field in form tag like below and add value of each radio button different value.

<form action="{% url "backtest" %}" method='POST' role='form' id='form'>
            {% csrf_token %}
      <input type="radio" name="tabs" value="first" id="toggle-tab1"  checked="checked" />
               <label for="toggle-tab1">Long</label>

               <input type="radio" name="tabs" value="second" id="toggle-tab2"    />
               <label for="toggle-tab2">Short</label>

               <input type="radio" name="tabs" value="third"  id="toggle-tab3"   />
               <label for="toggle-tab3">Long and Short</label>

....

When you submit this form you will get "tabs" in request.POST with value, So follow below code in view.

 if form.is_valid():
    if 'save' in request.POST:
                            obj = form.save(commit= False)
                            obj.user = request.user
                            tab_value = request.POST.get('tabs')
                            if tab_value == 'first':
             obj.strategy="Long"
                            elif tab_value == 'second': 
                             obj.strategy="Short" 
                            else : 
                             obj.strategy="Long and Short
