作爲類jinja2的形式

Question

我在Google App Engine中使用WTForm。我想作爲一個班級訪問我的表單。

這一點也適用djangoforms ...

class PostForm(djangoforms.ModelForm): 
    class Meta: 
    model = BlogPost 
    exclude = [ 'path', 'published', 'updated' ] 

我怎麼做WTforms相當。

class PostForm(model_form): 
    class Meta: 
    model = BlogPost 
    exclude = [ 'path', 'published', 'updated' ] 

我得到這個錯誤與回溯...

Answer 1

WTForms的model_form不採取任何元內部類的照顧。也許你可以覆蓋PostForm類的'__init__'方法。
