I have invoice/estimates django app, I need to write tests for it. Since
I'm a beginner with this, testing forms results hard for me.
This is the code - for models, form and admin:
# MODELS
class Invoice(models.Model):
subject = models.ForeignKey(
Subject,
verbose_name= _("Subject")
)
date = models.DateField(default=date.today())
tasks = models.ManyToManyField(
Task,
through='TaskCount',
)
discount = models.DecimalField(
max_digits=10,
decimal_places=2,
default=0
)
tip1 = models.BooleanField();
tip2 = models.BooleanField();
tax_a = models.BooleanField();
notes = models.CharField(max_length=500, blank=True)
expire = models.DateField(null=True, blank=True)
invoicenumber = models.IntegerField("Invoice number")
subtotal = models.DecimalField(max_digits=10, decimal_places=2,)
amount = models.DecimalField(max_digits=10, decimal_places=2,
default=0)
adi_start_date = models.DateField(null=True, blank=True)
adi_end_date = models.DateField(null=True, blank=True)
class People(models.Model):
first_name = models.CharField(
"First name",max_length=50, blank=True
)
last_name = models.CharField(
"Last name",max_length=50, blank=True
)
....
.... # other fields
def __unicode__(self):
return u"%s %s" % (self.first_name, self.last_name)
# model for inlines
class TaskCount(models.Model):
count_items = models.PositiveIntegerField("Qty", default=1)
task = models.ForeignKey(
'Task',
null=False)
estimate = models.ForeignKey(
'Estimate',
null=True,
blank=True
)
invoice = models.ForeignKey(
'Invoice',
related_name='task_count',
null=True,
blank=True
)
def __unicode__(self):
return u"%s" % (str(self.task.price))
class Task(models.Model):
label = models.CharField(
"Task name",
max_length=150
)
price = models.DecimalField(
"Price per session",
max_digits=10,
decimal_places=2,
default=0
)
is_adi = models.BooleanField(
default=False,
help_text=_("")
)
# FORMS
class InvoiceAdminForm(forms.ModelForm):
class Meta:
model = Invoice
def __init__(self, *args, **kwargs):
super(InvoiceAdminForm, self).__init__(*args, **kwargs)
....
# ADMIN
# inline
class TaskCountInline(admin.TabularInline):
model = TaskCount
extra = 0
fields = ('num_items', 'task')
def __init__(self, *args, **kwargs):
super(TaskCountInline, self).__init__(*args, **kwargs)
...
class InvoiceAdmin(admin.ModelAdmin):
list_display = ('subject', 'date', 'amount',
'discount', 'invoicenumber','get_pdf',
'edit_item', 'delete_item')
list_display_links = ('edit_item',)
filter_horizontal = ('tasks',)
search_fields = ['subject__first_name','subject__last_name']
actions = ['create_pdf']
inlines = (TaskCountInline,)
form = InvoiceAdminForm
fieldsets = (
.... # fieldsets ovverride
)
formfield_overrides = {
models.CharField: {'widget': forms.Textarea},
}
def get_pdf(self, obj):
opts = self.model._meta
return '<a href=%(reverse_url)s>' \
'<img src="/static/admin/img/blue-document-pdf.png"/>' \
'</a>' % {
'reverse_url':reverse(
'admin:%s_%s_pdf' % (
opts.app_label,
opts.object_name.lower()),
args=(obj.id,)
),
}
get_pdf.short_description = _("PDF")
get_pdf.allow_tags = True
def change_view(self, request, object_id, form_url='',
extra_context=None):
...
def get_urls(self):
urls = super(InvoiceAdmin, self).get_urls()
info = self.model._meta.app_label, self.model._meta.module_name
extra_urls = patterns('',
url(r'^(?P<object_id>\d+)/pdf/$',
self.admin_site.admin_view(self.pdf_view),
name='%s_%s_pdf' % info),
)
return extra_urls+urls
def pdf_view(self, request, object_id, extra_context=None):
"""
view for generating PDF objects
"""
....
def get_form(self, request, obj=None, **kwargs):
form = super(InvoiceAdmin, self).get_form(request, obj,
**kwargs)
form.base_fields['invoicenumber'].initial
=self.__get_last_invoice_nr_plus_one()
....
return form
def __get_last_invoice_nr_plus_one(self):
...
I'm trying to test the InvoiceAdminForm. this is the test code:
# FORM TESTS
class InvoiceAdminFormTestCase(TestCase):
def setUp(self):
self.subject = Preople.objects.create(
...
)
self.task1 = Task.objects.create(
...
)
self.task2 = Task.objects.create(
...
)
self.data = {
'subject':self.subject.id,
'csrfmiddlewaretoken':csrf._get_new_csrf_key(),
'tip1': 1,
'task_count-0-task': self.task1.id,
'subtotal': 67.00,
'amount': 69.68,
'_continue': 'Save and continue edit',
'task_count-0-id': '',
'task_count-__prefix__-task': '',
'notes': 'example notes',
'task_count-0-invoice':'',
'task_count-1-num_items': '1',
'invoicenumber': '4',
'task_count-__prefix__-invoice': '',
'adi_end_date': '',
'task_count-MAX_NUM_FORMS': '1000',
'discount': '0',
'dataìe': '25/11/2013',
'task_count-1-id': '',
'adi_start_date': '',
'task_count-1-invoice': '',
'task_count-0-num_items': '1',
'task_count-TOTAL_FORMS': '2',
'task_count-__prefix__-num_items': '1',
'task_count-__prefix__-id': '',
'task_count-INITIAL_FORMS': '0',
'task_count-1-task': self.task2.id,
'expire': ''
}
self.form = InvoiceAdminForm(data=self.data)
def test_valid_form(self):
self.assertTrue(self.form.is_valid(), msg=self.form.errors)
the test fails due to the lack of mandatory field 'tasks'. I can't explain
this. I've tried to save the form using admin interface, and it worked
without errors. Using ipdb debugger, I saved the data querydict and I used
it in the form case. So same data for populating the form, but different
results.
this is the traceback:
* # ./manage.py test gpf2*
* Creating test database for alias 'default'...*
* ======================================================================*
* FAIL: test_valid_form (gpf2.tests.test_forms.InvoiceAdminFormTestCase)*

Any help on that?
thanks
