value of checkbox aren't saved in the form

[farah_...@hotmail.com]

i am a beginner with Django. I don''t know what the problem with the value of checkbox. When i enter to the saved form the value of checkbox aren't save.The image is here . Please I need your help, I loose too much time on this.

This is my forms.py:

class BacktestForm(forms.ModelForm):

period_start = forms.DateField(initial=datetime.datetime.today().date() - datetime.timedelta(days=365+16), widget=forms.widgets.DateInput(format="%Y/%m/%d"), input_formats=["%Y/%m/%d"])

period_end = forms.DateField(initial=datetime.datetime.today().date() - datetime.timedelta(days=16), widget=forms.widgets.DateInput(format="%Y/%m/%d"), input_formats=["%Y/%m/%d"])

        

        market = forms.MultipleChoiceField(required=False,widget=CheckboxSelectMultiple, choices=MARKET_CHOICES)

        sector = forms.MultipleChoiceField(required=False,widget=CheckboxSelectMultiple, choices= MEDIA_CHOICES)

class Meta:

model = Parameters

This is my models.py:

class Parameters(models.Model):

user = models.ForeignKey(User)

title = models.CharField('title', max_length=100, default='', blank=True, help_text='Use an indicative name, related to the chosen parameters')

type = models.CharField('forecast type', choices=FORECAST_TYPES, max_length=20, default="backtest")

#input characteristics

price_1_min = models.FloatField('1. Price, min', default=0.1, validators=[MinValueValidator(0.1), MaxValueValidator(20000)])

def get_backtest_url(self):

return reverse('saved_backtest', kwargs={'pk': self.pk})

The save function in views.py:

 

        if request.method == 'POST':

if form.is_valid():

if 'save' in request.POST:

obj = form.save(commit= False)

obj.user = request.user

obj.type = "backtest"

obj.save()

messages.info(request, 'Saved!')

return redirect(obj.get_backtest_url())

The template for the saved form is :

 <div> {% if user.is_authenticated %}

{% if user.profile.is_active %}

                                     &nbsp; Saved from "Backtesting"

<ul>

{% for param in user.parameters_set.all %}

{% if param.type == "backtest" %}

                                                         <table style="width:100%">

                                                          <tr>

                                                           <th> Saved File </th>

                                                           <th> Created at </th>

                                                           

                                                          <tr> 

 

                                                           <td> <a href='{{param.get_backtest_url}}'>{{param.title}}  </a> </td>

  <td> {{param.created_at}} </td>

                                                           

         </tr>

        </table>

{% endif %}

{% endfor %}

</ul>

Your checkbox fields on the form are "market" and "sector", but your
"Parameters" model doesn't have fields with those names, and you
aren't doing anything with the values from the form in your save()
method.

Where were you expecting those checkboxes to be saved?

Cheers
