I have a django model for which I want to add custom actions. Where in this action I need to add one intermediate page with choice form (drop-down selection). I used below code to get this.
The Model Class:
class VerificationAdmin(admin.ModelAdmin):
list_display = ('id','asset_code', 'scan_time','credential','status','operator','location','auth_code','product_details')
list_filter = ('status','operator','location')
ordering = ('-scan_time',)
search_fields = ('asset_code',)
actions = ['set_interval']
class AddScanningIntervalForm(forms.Form):
_selected_action = forms.CharField(widget=forms.MultipleHiddenInput)
period_choice=["4 hrs","6 hrs","8 hrs","10 hrs","12 hrs"]
interval = forms.ChoiceField(choices=[(x, x) for x in period_choice])
@csrf_exempt
def set_interval(self, request, queryset):
print "before action"
form = None
if 'apply' in request.POST:
form = self.AddScanningIntervalForm(request.POST)
print "action taken"
if form.is_valid():
interval = form.cleaned_data['interval']
print interval
count = 0
for vObj in queryset:
print vObj.asset_code,vObj.status,interval
at=AlertTable(asset_code=vObj.asset_code,
status=vObj.status,interval=interval)
at.save()
count += 1
self.message_user(request, "Scanning Policy Successfully added to %s assets %s." %count)
return HttpResponseRedirect(request.get_full_path())
if not form:
form = self.AddScanningIntervalForm(initial={'_selected_action': request.POST.getlist(admin.ACTION_CHECKBOX_NAME)})
return render_to_response('admin/set_alert.html', {'verifications': queryset,'tag_form': form},context_instance=RequestContext(request))
set_interval.short_description = "Add Periodic Scanning Policy"
Add the template part:
<!DOCTYPE html>
{% extends "admin/base_site.html" %}
{% block content %}
<p>Select tag to apply:</p>
<form action="" method="post">
{{ tag_form }}
{% csrf_token %}
<p>The scanning policy will be applied to:</p>
<ul>{{ verifications|unordered_list }}</ul>
<input type="hidden" name="action" value="add_tag" />
<input type="submit" name="apply" value="Set Interval" />
</form>
{% endblock %}
It's working fine up to Intermediate page, but after selecting one of the alert choice in form at intermediate page and clicking on set Interval button I am getting result "no action selected"

This question is a bit old but for any future reference; make sure the 'action' input property in the intermediate form matches the admin function name. In this case 'set_interval' instead of 'add_tag'.
Also the POST context must contain '_selected_action' values which should match the selected items pks.
