Django - 复选框数组
我想在我的一个模板中取消多个复选框,但无法使其工作。
我试图在我的表单中传递一个包含 forms.BooleanField() 的数组,如下所示:
class ProjetSettingsForm(forms.Form):
## A bunch of form fields of no interest
arrayCheck = []
cb1 = forms.BooleanField()
cb2 = forms.BooleanField()
arrayCheck.append(cb1)
arrayCheck.append(cb2)
并在我的模板中像这样输出
{% for a in form.arrayCheck %}
{{ a }}
{% endfor %}
我的表单由视图调用:
def settings(request):
if request.method == "POST" and (request.POST.get("settings_task_type", "") == "Enregistrer Task Type"):
form = ProjetSettingsForm(request.POST, proj_id=request.session['proj'])
if form.is_valid():
settings = form.save_task_type()
c = {'proj':proj, 'form':form, 'settings':settings}
return render_to_response('projet/settings.html', c, context_instance=RequestContext(request))
else:
form = ProjetSettingsForm(proj_id=request.session['proj'])
settings = ""
c = {'proj':proj, 'form':form, 'settings':settings}
return render_to_response('projet/settings.html', c, context_instance=RequestContext(request))
但它显示:
<django.forms.fields.BooleanField object at 0xb595a2ec> <django.forms.fields.BooleanField object at 0xb595a22c>
如何让它正确显示复选框?
我需要将复选框作为数组而不是一一传递的原因是,它们会很多,而且我不会提前知道它们的确切数量,这取决于 sql 查询。
编辑:
如果有人看到这篇文章,我找到了解决方案。当我需要传递一系列复选框时,我不使用表单。
我直接从视图发送数组,在模板中创建复选框并在 request.POST.getlist('my_array')
中获取结果
I would like to out a number of checkboxes in one of my templates and I can't get it to work.
I'm trying to pass an array containing forms.BooleanField() in my form like :
class ProjetSettingsForm(forms.Form):
## A bunch of form fields of no interest
arrayCheck = []
cb1 = forms.BooleanField()
cb2 = forms.BooleanField()
arrayCheck.append(cb1)
arrayCheck.append(cb2)
and output it like this in my template
{% for a in form.arrayCheck %}
{{ a }}
{% endfor %}
My form is called by a view :
def settings(request):
if request.method == "POST" and (request.POST.get("settings_task_type", "") == "Enregistrer Task Type"):
form = ProjetSettingsForm(request.POST, proj_id=request.session['proj'])
if form.is_valid():
settings = form.save_task_type()
c = {'proj':proj, 'form':form, 'settings':settings}
return render_to_response('projet/settings.html', c, context_instance=RequestContext(request))
else:
form = ProjetSettingsForm(proj_id=request.session['proj'])
settings = ""
c = {'proj':proj, 'form':form, 'settings':settings}
return render_to_response('projet/settings.html', c, context_instance=RequestContext(request))
But it displays :
<django.forms.fields.BooleanField object at 0xb595a2ec> <django.forms.fields.BooleanField object at 0xb595a22c>
How can I get it to display the checkboxes correctly ?
The reason I need to pass the checkboxes as an array and not one by one is that there will be many of them and I won't know in advance their exact number, it depends on a sql query.
EDIT:
If someone comes across this post, i found a solution. I don't use a form when I need to pass an array of checkboxes.
I send the array directly from my view, create the checkboxes in the template and get the results in request.POST.getlist('my_array')

不要在表单之外使用表单字段。他们不是那样工作的。创建一个带有 MultipleChoiceField 的表单。
Don't use form fields outside a form. They don't work like that. Create a form with a MultipleChoiceField.
