showing the checked item alone without check box

问题

forms.py

PERSON_ACTIONS = (
    ('1', '01.Allowed to rest and returned to class'),
    ('2', '02.Contacted parents /guardians'),
    ('3', '02a.- Unable to Contact'),
    ('4', '02b.Unavailable - left message'),)

class PersonActionsForm(forms.ModelForm):
   action = forms.MultipleChoiceField(widget=forms.CheckboxSelectMultiple(), choices=PERSON_ACTIONS, required=False, label= u"Actions")

models.py

class Actions(models.Model):
    report = models.ForeignKey(Report)
    action =  models.IntegerField('Action type')

print.html

{{ actionform.as_p}}

The PersonActionsForm contains the items with multichoice checkbox. In report registration page,the user can select any one or more item.The checked items are saved in models as integer values.

Since i am rendering the whole form it is showing the entire form with checked and unchecked item.

In print page,i want to show only the checked item alone without checkbox.

How to do this in django.

Thanks

Based on James's answer. You can move PERSON_ACTIONS to your model and import it in form.

models.py:

PERSON_ACTIONS = (
    ('1', '01.Allowed to rest and returned to class'),
    ('2', '02.Contacted parents /guardians'),
    ('3', '02a.- Unable to Contact'),
    ('4', '02b.Unavailable - left message'),
)
PERSON_ACTIONS_DICT = dict(PERSON_ACTIONS)

class Actions(models.Model):
    report = models.ForeignKey(Report)
    action =  models.IntegerField('Action type')

    def action_as_text(self):
        return PERSON_ACTIONS_DICT.get(str(self.action), None)

forms.py:

from .models import PERSON_ACTIONS

class PersonActionsForm(forms.ModelForm):
    action = forms.MultipleChoiceField(
        widget=forms.CheckboxSelectMultiple(), 
        choices=PERSON_ACTIONS, 
        required=False, 
        label= u"Actions"
    )

Get the actions in views.py:

actions = Actions.objects.filter(....)
return render(request, 'your_template.html', {
    .....
    'actions': actions   
})

... and render it in template:

{% for action in actions %}
    {{ action.action_as_text }}
{% endfor %}

Hope this helps.

You shouldn't be using forms for non-edit display purposes. Instead, make a method on your class:

from forms import PERSON_ACTIONS
PERSON_ACTIONS_DICT = dict(PERSON_ACTIONS)

class Actions(models.Model):
    report = models.ForeignKey(Report)
    action =  models.IntegerField('Action type')

    def action_as_text(self):
        return PERSON_ACTIONS_DICT.get(str(self.action), None)

Then you can just do {{ obj.action_as_text }} in a template and get the text you want. Note that it would probably be more common to use integers in the PERSON_ACTIONS array (then you don't need the str call in action_as_text.)
