[英]Django: Testing the 'clean' method of a custom ModelForm using Model-Mommy
======= Update ======= ======= 更新 =======
@JF brought forward a brilliant perspective for the use of model mommy in ModelForms. @JF提出了在ModelForms中使用模型妈妈的出色观点。
With the following code, I managed to automatically generate random data for all the fields of the model, except for the ones I would like to manipulate. 通过以下代码,我设法为模型的所有字段自动生成随机数据,但我想操纵的数据除外。
tests.py: tests.py:
from django.test import TestCase
from houses.forms import ManForm
from houses.models import Man
class ModelsTest(TestCase):
def test_Man(self):
man = mommy.make('Man', age=20)
data = {each_field.name: getattr(man, each_field.name) for each_field in man._meta.fields}
data.update({'age_verification': 20})
form = ManForm(data)
self.assertTrue (form.is_valid())
models.py models.py
from django.db import models
class Man(models.Model):
name = models.CharField(max_length = 12)
age = models.PositiveSmallIntegerField()
forms.py: forms.py:
from my_app.models import Man
from django import forms
from django.core.exceptions import ValidationError
class ManForm(forms.ModelForm):
age_verification = forms.IntegerField()
def clean(self):
if not self.cleaned_data['age'] == self.cleaned_data['age_verification']:
raise ValidationError("Is this a LIE?")
class Meta:
model = Man
fields = ['name', 'age', 'age_verification']
For the time being, I test it like this: 目前,我这样测试:
tests.py: tests.py:
from django.test import TestCase
from houses.forms import ManForm
class ModelsTest(TestCase):
def test_Man(self):
data = {
'name' = 'John',
'age' = 20,
'ege_verification' = 20,
}
form = ManForm(data)
Is there a tool that provides random data for Forms? 是否有提供表格随机数据的工具? Or ... can I use the available tools for models for this purpose?
或者...我可以为此目的使用可用的模型工具吗? Searching the docs of those supporting Python 3, I did not understand how this could be achieved.
在搜索那些支持Python 3的文档时,我不知道该如何实现。
The only one that clearly provides such a service is Django-Whatever which is not python3 compatible. 唯一明显提供这种服务的是Django-Whatever ,它与python3不兼容。
If you don't want to type the name of each attribute, you can do this: 如果您不想键入每个属性的名称,则可以执行以下操作:
from model_mommy import mommy
from django.forms import model_to_dict
class ModelsTest(TestCase):
def test_Man(self):
man = mommy.make('Man')
data = model_to_dict(man)
form = ManForm(data)
You could do something like this: 您可以执行以下操作:
from model_mommy import mommy
class ModelsTest(TestCase):
def test_Man(self):
man = mommy.make('Man', _fill_optional=True)
data = {
'name': man.name,
'age': man.age,
'age_verification': man.age_verification,
}
form = ManForm(data)
