Below is some of my code. If you need more information please let me know.
models.py
```tags = TaggableManager()```
```forms.py
fields = ['title','content','snippet','thumbnail_image','tags']
widgets= {
'tags' : TagWidget(attrs={'data-role':'tagsinput','placeholder':'Add Tags','class':'form-control'}),
'title': forms.TextInput(attrs={'class':'form-control'}),
'snippet': forms.Textarea(attrs={'class':'form-control','rows':3}),
'thumbnail_image': forms.ClearableFileInput(attrs={'class':'form-control'})
}```
Here is an example of what I am trying to do.
```res = self.client.post(BLOG_CREATE_URL,
{'title': 'Greatest blog ever',
'content': "hahahahah nicuuu!!" ,
'thumbnail_image': 'blog/test/gibson-vintage.jpg',
'snippet': 'good snippet', 'tags': ?,
})```
The response code should should be 302 but it shows 200. So I tested the forms and it shows form is not valid.
I have no idea how to continue the test. I am new django. Can someone help me? Thank you in advance.
